Description

Anti-adhesion uterus support

Technical Field

The invention relates to the field of medical consumables, in particular to a sac type uterine cavity bracket for preventing postoperative uterine wall adhesion.

Background

The pathological phenomenon of partial or complete adhesion of the uterine cavity wall after the intrauterine membrane is damaged, namely, the intrauterine adhesion, is often caused. Intrauterine adhesions can often cause menstrual abnormalities such as hypomenorrhea, amenorrhea, and the like. Patients with intrauterine adhesions are prone to miscarriage, premature labor, ectopic pregnancy, intrauterine death, placental implantation, placental adhesions, even infertility, etc. The current treatment approach for patients suffering from severe intrauterine adhesions is to perform surgical separation, but re-adhesions are very likely to occur due to slow or poor regeneration of the endometrium after surgery.

At present, a Foley balloon catheter or a balloon uterine stent is usually placed immediately after operation in clinic for physical separation to prevent (re) adhesion. The balloon stent which is more in use in the market at present has the shape similar to the shape of uterus, has better anti-adhesion effect and can also play a role in hemostasis. However, the bag wall is pressed on the inner wall of the uterine cavity because of the sufficient contact with the inner wall of the uterine cavity, thereby affecting the convection of the intrauterine liquid, preventing the effect of intrauterine drainage liquid, and being unfavorable for the discharge of intrauterine effusion/blood stasis (or blood seepage) and the blood circulation of the uterine wall and the healing of the operation wound surface.

Disclosure of Invention

In order to solve the problems of the prior saccule support in use, the invention provides an anti-adhesion uterine support which not only has the function of preventing uterine cavity adhesion, but also has better capacity of draining intrauterine liquid, so that intrauterine effusion/congestion can be timely discharged, and the healing of uterine wound surfaces is facilitated.

The technical scheme adopted for solving the technical problems is as follows: an anti-adhesion uterus support comprises a balloon, a catheter connected with the balloon, a tube balloon arranged on the outer wall of the balloon and a balloon knot arranged at the junction of the balloon and the catheter, wherein a cavity is formed between the balloon knot and a wall body opposite to the balloon.

The catheter is provided with a pipeline which is respectively communicated with the sacculus cavity, the sacculus cavity of the pipe sacculus and the cavity.

The tubular bladder, when inflated, can form a drainage channel that can communicate directly or indirectly with the uterine cavity and extends into the cavity at its ends.

When only the balloon is inflated, the wall of the tube balloon can be stretched along with inflation of the balloon, and the wall of the tube balloon can be always clung to the outer wall surface of the balloon. When the balloon is inflated to a certain extent and liquid or gas is required to be injected into the tube balloon to expand the tube balloon, the balloon wall of the tube balloon can be further stretched to form an outwards protruding structure relative to the balloon along with the increase of the injection amount of the liquid or the gas.

The inflation and the shrinkage of the balloon can be independently controlled through the pipeline communicated with the balloon cavity of the balloon, and the inflation and the shrinkage of the tube balloon can be independently controlled through the pipeline communicated with the balloon cavity of the tube balloon, so that the stent can be selected to mainly play the purpose of hemostasis treatment according to the treatment process, or the purpose of diversion treatment and the purpose of improving the blood circulation condition of the uterine cavity are required to be properly carried out, and the inflation state and the inflation degree of the balloon, and the inflation state and the inflation degree of the tube balloon are respectively regulated and controlled.

In some embodiments of this patent, the balloon is coated with an absorbable drug, such as an antibacterial drug, an ablative drug, or the like, on its exterior. Both the balloon and the tube balloon are made of absorbable materials.

Further, in order to ensure that the inner wall of the balloon knot, i.e. the inner wall of the cavity is smooth and flat, wrinkles of stagnant fluid/blood are avoided, the balloon knot is provided with a balloon cavity, the balloon cavity is communicated with the balloon cavity of the tube balloon, or a branch pipeline is independently arranged on the catheter and communicated with the balloon cavity of the balloon knot, and the branch pipeline is used for injecting liquid or gas into the balloon cavity of the balloon knot to control the inflation and retraction states of the balloon knot.

The balloon knot is provided in a structure form with a balloon cavity, so that the radial distance (formed by the outer wall of the balloon) of the cavity can be better controlled, and the effusion/blood stasis can be smoothly discharged from the cavity.

In particular operation, when the balloon cavity of the balloon knot is fully inflated, the inflation degree of the balloon cavity of the balloon can be relatively weakened so as to promote the sufficient spacing of the cavity relative to the balloon.

If the balloon knot does not have a balloon cavity structure, the inflation degree of the balloon can only be controlled to regulate and control the size of the interval formed by the cavity relative to the outer wall of the balloon.

Further, the balloon knot can be inflated to enable the port of the cavity to be annular, and the inner wall of the cavity can be kept at a distance from the inflated outer wall of the balloon. After the balloon knot is inflated, the port of the cavity is annular and corresponds to the lower part of the balloon at intervals, so that effusion/blood stasis can be drained from the wall body of the balloon into the cavity more quickly and omnidirectionally. The drainage effect can be better when the drainage device is matched with the implementation means of arranging a plurality of tube bags.

Further, a plurality of tube bags which are distributed at intervals are arranged on the outer wall of the balloon, and each tube bag respectively extends into the cavity around the periphery of the outer wall of the balloon and two end parts of the tube bag. When a plurality of tube bags are arranged, drainage channels can be formed on at least part of the tube bags. The residual other tube bags can be provided with or without a drainage channel, and when the drainage channel can be formed, a needle hole is arranged on the bag wall forming the drainage channel, if the tube bag is used for inputting medicines (such as antibacterial medicines, ablative medicines or hormones), the medicines can permeate into the bag cavity from the inflated needle hole and rapidly diffuse onto the wall of the uterine cavity by means of the drainage channel, after the medicine is conveyed, the tube bag is contracted to the original state, the needle hole is contracted and sealed in the bag wall forming the drainage channel, and the entry of effusion/congestion can be effectively prevented. Preferably, a tube bag is arranged in the middle of the side surface of the balloon, and at least one tube bag is arranged on the upper end surface and the lower end surface of the balloon respectively by taking the tube bag as a boundary. The distance between the tube bags arranged on the two end surfaces and the tube bag arranged in the middle of the side surface gradually increases from one end of the balloon, which is far away from the balloon knot, to one end of the balloon knot.

When a plurality of tube bags are arranged, a unit tube can be respectively arranged for each tube bag, and liquid or gas is injected or pumped back into each tube bag through each unit tube to control the expanding and contracting states of each tube bag. The multiple tube bags can be divided into multiple groups according to the arrangement function of the tube bags, each group is independently provided with a unit tube, liquid or gas is injected or pumped into each group of tube bags through each unit tube, so that the inflation and contraction states of each group of tube bags are controlled, and the bag cavities among the tube bags of the same group are communicated with each other. For example, if a certain group of tube bags is used for injecting therapeutic drugs into uterine cavities of uterus, needle holes can be arranged on the bag walls of the reorganized tube bags, the needle holes can be unfolded enough to exude the drugs outwards after the tube bags are inflated, and the needle holes are tightly closed after the tube bags are contracted to an initial state (when liquid or gas in the bag cavities are emptied), so that liquid such as effusion/blood stasis can hardly flow into the reorganized tube bags through the needle holes. Under the multi-balloon structure, the utility of the separate-arranged balloons is convenient, which creates implementation conditions for diversified implementation of treatment means and postoperative secondary treatment, and is helpful for faster and better postoperative healing and recovery.

Further, a side branch is provided on the catheter and communicates with the lumen. The side branch pipe is communicated with the cavity, a reliable channel is created for the mini-type inspection instrument or therapeutic instrument or drug administration instrument to be inserted in the postoperative recovery process, and the size of the void space in the uterine cavity can be controlled by controlling the relative expansion degree among the balloon cavity of the balloon, the balloon cavity of the tube balloon and/or the balloon cavity of the balloon knot. The structure is preferably implemented in combination with a scheme with a plurality of tubular sacs, because the tubular sacs can form a net-shaped support in the uterine cavity, the inner wall of the uterine cavity is better separated, a large enough void space is formed in the uterine cavity, and a large enough wall surface of the uterine cavity is exposed, so that the examination, treatment and administration operations are conveniently and effectively implemented, and the accuracy and the comprehensiveness of the examination, treatment and administration are better ensured. It is also preferable to implement the balloon knot with a balloon lumen structure, because such a mating structure allows for easier access to the micro-instruments/devices from the lumen formed at the balloon knot.

Further, the drainage channel is arranged on the side surface of the tubular sac and/or the end surface of the tubular sac. When a plurality of tube bags are arranged, the structure selection of the drainage channel is properly determined according to the positions of the tube bags on the wall surface of the balloon, and the drainage channel can be selected in different forms.

Further, the wall surface is an arc surface after the tube bag is inflated, the drainage channel is formed in the bag tube, and the outer wall of the bag tube is provided with a drainage hole communicated with the drainage channel. The plurality of diversion holes are distributed at intervals along the surrounding direction of the tubular sac. The arrangement can ensure that convection channels are arranged in the uterine cavity along the transverse direction and the longitudinal direction, the flowing capacity of liquid in the uterine cavity is improved, a good convection state is kept, and effusion/blood stasis can be discharged in time.

In some embodiments, when the notch of the drainage channel is in an open form, particularly when the drainage channel is disposed on the side of the tubular bladder, and the notch faces outwards, it is preferable to dispose the diversion holes penetrating through the two end surfaces (in which case the diversion holes disposed on the two end surfaces are opposite) or penetrating from the end surfaces into the drainage channel (in which case the diversion holes disposed on the two end surfaces are desirably staggered), and the diversion holes are still alternately disposed along the circumferential direction of the tubular bladder.

The beneficial effects are that:

the uterus support provided by the patent not only has the function of preventing the adhesion of the uterine cavity, but also creates a drainage structure outside between the saccule and the uterine cavity by singly controlling the expansion and retraction states and degrees of the tubular saccule arranged on the outer wall of the saccule, effectively promotes the flow of the effusion/blood stasis in the uterine cavity, rapidly discharges the effusion/blood stasis outside by means of the formed drainage structure, can also control the compression state and compression degree of the uterine cavity wall, improves the blood circulation condition of the inner wall of the uterine cavity, and creates a more suitable environment for healing of the wound surface of the uterine cavity.

In the early stage of putting the support into the uterine cavity, the main aim is to stop bleeding by pressing the wall surface of the uterine cavity by means of the balloon, at the moment, the balloon wall of the tube balloon can be tightly attached to the outer wall of the balloon, and the pressing of the balloon to the uterine interior cannot be influenced, because the balloon wall of the tube balloon can be quite thin along with the inflation of the balloon, and obvious protrusions cannot be formed on the inflated balloon outer wall.

When the tube bag is provided with a plurality of tube bags, conditions can be created for post-operation supplementary treatment, and the recovery and healing progress of severe patients can be quickened. The reticular support formed by the plurality of tubular sacs can prop up the uterine cavity, and most of the wall surface of the uterine cavity is exposed, thereby being beneficial to checking the recovery degree by means of a micro instrument penetrating into the uterine cavity and implementing post-operation supplementary treatment, such as cleaning or drug administration, on the wound surface. If the device is designed to be an implementation mode capable of controlling the inflation and retraction states and degrees of all the tube bags (or all groups of tube bags) through independent pipelines, part of the tube bags (or a certain group of tube bags) are inflated successively conveniently and switchably according to the specific positions of examination and the specific positions of wound surfaces needing supplementary treatment.

Also, the terms such as "upper", "lower", "front", "rear", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the invention for which the invention may be practiced or for which the relative relationships may be altered or modified without materially altering the technical context.

The anti-adhesion uterine stent shown in fig. 1 to 9 comprises a balloon 1, a tube balloon 2 arranged on the outer wall of the balloon 1, a catheter 3 connected with the balloon 1 and a balloon knot 7 arranged at the junction of the balloon 1 and the catheter 3, wherein a cavity is formed between the balloon knot 7 and the opposite wall body of the balloon 1.

The catheter is provided with a pipeline which is respectively communicated with the balloon cavity of the balloon 1, the balloon cavity of the tube balloon 2 and the cavity, and is respectively corresponding to a first branch pipe 4, a second branch pipe 5 and a third branch pipe 6, as shown in figures 1, 3, 5 and 8-9. The first branch pipe 4 can be used for injecting liquid (such as physiological saline and the like) or gas into the balloon 1 so that the balloon 1 is inflated to form a support for the uterine cavity and play a role in preventing the adhesion of the inner wall of the uterine cavity. The second branch pipe 5 can be used for injecting liquid (such as normal saline, medicines and the like) or gas into the tubular sac 2 to expand the tubular sac 2, and the balloon 1 which can be expanded relatively protrudes outwards, at this time, a certain gap is formed between the outer wall of the balloon 1 and the inner wall of the uterine cavity at the position on the balloon 1, the gap size can be distinguished according to the expansion degree of the balloon and/or the expansion degree of the tubular sac, a low-pressure area is formed in the uterine cavity at the gap, and the accumulation of liquid (such as blood stasis, secretion and the like) in the uterine cavity is facilitated to be converged towards the gap. A communication between the uterine cavity and the outside is established via the communication between the third branch 6 and the cavity.

The tubular bladder 2, when inflated, can form a drainage channel 22, which drainage channel 22 can communicate directly or indirectly with the uterine cavity and extend end-wise into said cavity. The design of the drainage channel 22 helps to guide the fluid accumulation in the uterine cavity to said cavity and to drain to the outside via the third branch 6.

As in the embodiment shown in fig. 1, 2, 5, 8, the catheter 3 is a coaxial multi-lumen structure comprising an outer tube, an intermediate tube and an inner tube. The first branch pipe 4 is communicated with a cavity formed between the middle pipe and the inner pipe, the tail end of the middle pipe extends into the balloon cavity of the balloon 1, and a hole is formed in the side wall of the section (middle pipe) positioned in the balloon cavity (balloon 1) so that the cavity is communicated with the balloon cavity of the balloon 1. The second branch pipe 5 is communicated with the lumen of the inner pipe, and the tail end of the inner pipe extends to the end of the balloon 1 opposite to the end where the balloon knot 7 is arranged and is communicated with the balloon lumen 21 of the catheter balloon 2. The third branch tube 6 communicates with a lumen formed between the outer tube and the intermediate tube and the end of the outer tube extends to the balloon junction 7 so that the lumen communicates with the lumen (formed between the balloon junction and the opposite face of the balloon).

As in the embodiment shown in fig. 3, the catheter 3 is still a coaxial multi-lumen structure comprising an outer tube, an intermediate tube and an inner tube, the lumen of the inner tube being the central tube 31, the lumen between the inner tube and the intermediate tube being the intermediate tube 32, the lumen between the intermediate tube and the outer tube being the outer tube 33. The end of the inner tube extends into the balloon cavity of the balloon 1, the end of the intermediate tube extends to the balloon knot 7 or just into the balloon 1 and is provided with a wall hole 321 in the side wall communicating with the balloon cavity 21 of the tube balloon 2, the end of the outer tube extends to the balloon knot 7 so that the outer tube 33 communicates with the cavity (formed between the balloon knot and the opposite face of the balloon) or with the drainage channel 22. The first branch pipe 4 is communicated with the central pipeline 31, and can inject liquid into the balloon 1 to expand the balloon to support the uterine cavity of the uterus, so that postoperative adhesion is prevented. The second branch pipe 5 is communicated with the middle pipeline 32, can be filled with liquid into the pipe bag 2 through the wall hole 321 to expand to form an outward protruding structure relative to the balloon 1, establishes a gap between the inner wall of the uterine cavity and the outer wall of the balloon to form a negative pressure area, promotes the accumulation of liquid/blood stasis in the uterine cavity to the area and sends the liquid/blood stasis to the cavity through the drainage channel 22, and finally is discharged to the outside through the third branch pipe 6 along the outer pipeline 33.

The embodiment shown in fig. 9 with respect to the catheter 3 can be seen with reference to fig. 3, and additionally a conduit is provided in communication with the central branch 8, which conduit extends into the lumen at its end. In the embodiment shown in the figures, the outer wall of the conduit is formed with a transfer chamber, to which the side branch 8 is connected, the radial dimension of one side of the outer conduit 33 facing upwards of the transfer chamber being increased relative to the other side. The transfer chamber is provided with a one-way closing plate (the cover on the closing plate can only open towards the transfer chamber, i.e. can be pushed open only when the guiding hose 91 is inserted into the transfer chamber through the side branch pipe 8, and cannot be pushed open in the opposite direction) to prevent effusion from flowing into the side branch pipe 8.

As in the embodiments shown in fig. 1 to 4 and 9, the tube balloon 2 is provided on the side of the balloon 1 (the balloon 1 is designed to simulate the shape of the uterine cavity) in the middle (the middle in thickness) and surrounds the side wall of the balloon 1 for one circle (the outline projection of the tube balloon 2 after inflation is similar to the outline projection of the balloon). The drainage channel 22 formed in the cuff 2 opens outwards (arrow a) and has a cross-sectional shape similar to (i.e. comparable to) that of fig. 6 (6.1). The effusion in the uterine cavity is converged into the drainage channel 22 along the outer wall of the balloon 1 towards the tubular balloon 2, flows to the uterine cavity along the drainage channel 22, and finally is discharged to the outside of the body through the third branch pipe 6.

In the embodiment shown in fig. 5, two tubular bags 2 are provided, the distribution surfaces of which are relatively vertical (including the similar vertical situation, such as that the distribution surfaces of the two are crossed into an X shape), all encircle the outer wall of the balloon 1, and convergence is formed at the end part of the balloon 1 (a hole channel for injecting liquid or gas into the two tubular bags is formed at the convergence position). Drainage channels 22 arranged on the tubular sac 2 are formed inside the tubular sac 2, and drainage holes 23 distributed on the tubular sac 2 at intervals are communicated with the uterine cavity of the uterus. The cross-sectional shape of the drainage channel 22 is similar to (i.e., can be referred to as) 6.2 in fig. 6, and the tubular bladder body of the tubular bladder 2 is provided with tubular bladder holes 25, and when the tubular bladder 2 is inflated by injecting liquid/gas, the tubular bladder holes 25 are inflated synchronously to support the channels 251 which communicate with the drainage channel 22. The arrangement can ensure that convection channels are arranged in the uterine cavity along the transverse direction and the longitudinal direction, the flowing capacity of liquid in the uterine cavity is improved, a good convection state is kept, and effusion/blood stasis can be discharged in time. In the embodiment of fig. 1, the notch of the drainage channel 22 is in an open form, and is arranged on the side surface of the tubular bag 2, the notch faces outwards (indicated by an arrow a), and the drainage holes penetrating through the two end surfaces of the tubular bag (the drainage holes arranged on the two end surfaces are opposite) or penetrating from the end surfaces into the drainage channel (the drainage holes arranged on the two end surfaces are wanted to be staggered), and the drainage holes are still arranged alternately along the surrounding direction of the tubular bag (the same as shown in fig. 5). The scheme of fig. 1 is improved to ensure that convection channels are formed in the uterine cavity along the transverse direction and the longitudinal direction, so that the flowing capacity of liquid in the uterine cavity is further improved, a good convection state is maintained, and accumulated liquid/congestion can be discharged in time.

As in the embodiment shown in fig. 7, the tube balloon 2 is provided on the side of the balloon 1 (the balloon 1 is designed to simulate the shape of the uterine cavity) in the middle (the middle in thickness) and around the side wall of the balloon 1 for one revolution (the outline projection of the inflated tube balloon 2 is similar to the outline projection of the balloon). A drainage channel 22 provided on the tubular bag 2 is formed on the end face of the tubular bag 2, and communication channels 24 communicated with the cavity are provided at the two ends of the drainage channel 22 extending to the cavity. The cross-sectional shape of the drainage channel 22 is similar (i.e. can be referred to) to that of fig. 6 (6.3).

As shown in the embodiment of fig. 8, a plurality of tube bags 2 are arranged on the outer wall of the balloon 1 and are distributed at intervals, and each tube bag 2 is wound around the outer wall of the balloon 1 at one circle and both ends extend into the cavity. As shown in the figure, a tubular balloon 2 is provided in the middle of the side surface of the balloon 1, and the tubular balloon 2 is also provided on the upper and lower end surfaces of the balloon 1 with the tubular balloon 2 as a boundary. The distance between the tube bag 2 arranged on the two end surfaces and the tube bag 2 arranged in the middle of the side surface gradually increases from one end of the balloon 1 far away from the balloon knot 7 to one end provided with the balloon knot 7. In some embodiments, at least one ring of tube (on the end) may be provided inside the tube (on the end) on the end of the balloon 1.

It should be noted that, when there are a plurality of tube bags provided on the balloon, the structure of the drainage channel formed on each tube bag may be one or more of three forms shown in fig. 6.

The plurality of tube bags 2 are arranged, so that negative pressure areas in a plurality of directions can be formed between opposite surfaces of the uterine cavity and the sacculus in a supporting way, on one hand, effusion/congestion can be discharged, infection is avoided, more favorable conditions are created for postoperative recovery of the uterine cavity, and wound healing is quickened; on the other hand, the size of the contact surface between the saccule and the uterine cavity can be selectively reduced, the compression situation of the saccule on the uterine cavity is controlled, the blood circulation condition of the uterus is improved, the postoperative recovery process is further promoted, and the wound healing is further accelerated.

With a plurality of the tube bags 2, a drainage channel 22 can be formed on at least part of the tube bags 2. The remaining other tube bags 2 can be formed with or without drainage channels, and when the drainage channels can be formed, pinholes are arranged on the formed drainage channel bag walls, if a part of the tube bags are used for inputting medicines, the medicines can permeate into the uterine cavity from the swelled pinholes and rapidly diffuse to the uterine cavity walls by means of the drainage channels, after the medicine is conveyed, the part of the tube bags shrink back to the original state, the pinholes shrink and are covered in the bag walls forming the drainage channels, so that the liquid accumulation/blood stasis can be effectively prevented, and the cross section of the drainage channels on the tube bags is preferably the structure shown in (6.1) and (6.2) in fig. 6, and can be further optimized so as to be more beneficial to the rapid and uniform diffusion of the medicines.

As shown in fig. 1, 3, 8 and 9, each of the above-mentioned tubular bags continuously surrounds the balloon outer wall for one turn, and the end face of the inflated outer wall is a smooth curved surface. In some specific embodiments, a plurality of grooves are formed on the end face of the inflated tubular bag, the grooves are alternately arranged along the surrounding direction of the tubular bag, the outer ports of the grooves extend to the outer ports (the ports pointed by a) of the drainage channels, so that accumulated liquid/congestion can flow to the drainage channels faster along the grooves and be discharged in time, and better conditions are created for healing of wound surfaces of uterine cavities.

In particular, the balloon knot 7 can have a balloon cavity structure, and the balloon cavity of the balloon knot 7 is communicated with the balloon cavity of the tube balloon 2, so that the balloon knot can be inflated at the same time. Alternatively, the balloon knot 7 may have a balloon lumen structure, the inflated state of which can be controlled individually (in this case, it is necessary to provide a channel structure on the catheter 3, which is in separate communication with the balloon knot 7). Through setting up the sac knot 7 that has the sac chamber structure, can form bearing structure in the junction position of palace chamber and cervical, push away sacculus 1 to the palace intracavity better, help reinforcing sacculus to the oppression effect of palace chamber, play the effect of hemostasis by compression better.

When the tube bags 2 are provided with a plurality of tube bags, part of the tube bags can be selected so that the bag cavities of the tube bags are communicated with the bag cavity structures of the bag junctions 7, or the bag cavities of all the tube bags 2 are communicated with the bag cavity structures of the bag junctions 7.

When the plurality of tube bags 2 are provided, one communicating tube (the free ends of the plurality of communicating tubes extend from the ports of the second branch tube) may be provided for each tube bag 2, or one communicating tube may be provided for each of the part of the tube bags, and one communicating tube may be provided for the rest of the tube bags. At this time, pinholes are provided on the wall of a part of the balloon (the pinholes can be inflated after the balloon is inflated, and the pinholes are almost closed before the balloon is not inflated), and particularly, the balloon 2 of the communicating tube is separately provided, and the part of the balloon tube 2 is used for injecting medicine into the uterine cavity so as to better promote recovery or implement treatment.

The balloon knot 7 can enable the port of the cavity to be annular after being inflated, and the inner wall of the cavity can keep a distance relative to the outer wall of the inflated balloon 1, so that drainage of accumulated liquid/blood stasis is facilitated. If the balloon knot 7 has a balloon cavity structure, an outward turned edge opening can be formed at the port after the balloon knot 7 is inflated, an outward turned edge opening is formed at the port similar to the bowl opening, and a support is formed near the position where the uterine cavity and the cervix are combined by means of the outward turned edge, so that the effusion/blood stasis is prevented from entering the cervix, and is more fully discharged to the outside through the cavity by the third branch pipe 6, and the infection is better avoided.

As shown in fig. 9, the catheter 3 is provided with a side branch 8, and the side branch 8 communicates with the lumen. By means of the side branch pipe 8, an inspection instrument can be inserted into the uterine cavity of the uterus or directional administration can be performed, so that the recovery condition of the uterine wound surface can be inspected or supplementary treatment can be implemented. The guiding and controlling hose 91 with miniature monitoring instrument (ultrasonic detector, camera, etc.) and/or medicine feeding instrument and/or therapeutic instrument is connected with the monitor 9, and the action and orientation of the end of the guiding and controlling hose 91 can be controlled by the monitor 9, and the real-time picture in the uterine cavity can be displayed on the display thereof, so that the condition in the uterus and the action of the end of the guiding and controlling hose 91 can be observed better.

After the balloon knot 7 is inflated, the port of the cavity is fully opened, and the end head of the guiding hose 91 is easily controlled to extend into the uterine cavity through the port. The guiding hose 91 is internally provided with a tensile wire and a data cable (the prior art can solve the problem, and many application scenarios are not repeated).

When the guiding and controlling hose 91 is fed into the uterine cavity, the tubular bag 2 is controlled to expand to a certain extent, at this time, the pump 92 connected with the second branch pipe 5 can be arranged, the pump 92 is controlled by the monitor 9, the second branch pipe 5 is provided with the pressure gauge 51, and the pressure gauge 51 is preferably connected with the monitor 9, so that the monitor 9 can control the working state (pumping-in or pumping-out) of the pump 92 in real time according to the fed-back pressure value. Under this embodiment, by means of the control of the monitor 9 on the pump 92, the pump can be automatically started-stopped at a certain time interval, and the pump can be circularly pumped and pumped (the pumping quantity can be set by the detector each time) at a certain frequency in a certain starting operation time, so that the tube bag has continuous expansion and contraction change state, thereby promoting the flow of the fluid/blood stasis in the uterine cavity, further improving the drainage effect and facilitating the discharge of the fluid/blood stasis.

In some operations, the balloon may be inflated to some extent and then inflated to a relatively greater extent as the tube balloon 2 is inflated. The specific requirement is selected according to the purpose and the actual requirement.

If the balloon knot 7 has a separate balloon lumen structure and the inflated state can be controlled individually, it is also possible to control only the inflation of the balloon knot 7 to a certain extent, whereas the lumen formed between the balloons 1 is first accessed from the balloon knot 7 into the pilot hose 91.

The side branch pipe 8 is provided for extending the guiding and controlling hose 91 into the uterine cavity, and the number of the tube bags 2 is preferably a plurality, so that the uterine cavity can be better supported by the tube bags 2, the wall surface of the uterine cavity is separated from the balloon, a larger movable space is created for the end part of the guiding and controlling hose 91, and the examination or treatment operation is convenient to implement. Preferably, in such an embodiment, inflation of each tube bladder 2 can be controlled separately (i.e., the tube bladders are not in communication with each other).

The wall surface is the cambered surface after the tube bag is inflated, the drainage channel is formed in the bag tube, and the outer wall of the bag tube is provided with a diversion hole 23 communicated with the drainage channel.

In the application of the patent scheme, the main function of the balloon 1 is compression hemostasis and support anti-adhesion. The main function of the tube bag and the bag knot is to create a drainage channel so as to timely and fully discharge the accumulated liquid/congestion in the uterine cavity to the outside of the body, thereby creating better conditions for the healing recovery of the uterine cavity after operation and avoiding infection. Therefore, in general, the balloon and the tube balloon are not simultaneously in the inflated state for a long time, more often the balloon is kept in the inflated state, and the tube balloon is intermittently inflated to form a protruding structure relative to the balloon, so that an automatic controller is preferably arranged for controlling the inflation and retraction of the tube balloon. When the tubular saccule is inflated, the inflation degree of the saccule is relatively weakened so as to play the role of supporting and anti-adhesion, promote the effusion/congestion drainage effect and improve the blood circulation condition of the uterine wall, and ensure better and faster healing and recovery of wounds.

As shown in fig. 4, only when the balloon 1 is inflated, the wall of the tube balloon 2 is tightly attached to the outer wall of the balloon 1 (the balloon 1 is inflated simultaneously with inflation, but the lumen of the tube balloon is not inflated-that is, the lumen walls of the tube balloon are tightly attached to each other). After the balloon 1 is inflated, liquid or gas is injected into the tubular balloon 2 to inflate the tubular balloon, and the tubular balloon 2 can form an outwardly protruding structure relative to the outer wall of the balloon 1. In the case of a balloon 1 that is completely uninflated, it is preferable to only inflate the tubular balloon 2 to form a protruding support structure, with limited drainage and support effects, either for short periods of time or for special purposes only.

The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. The present invention is capable of modifications in the foregoing embodiments, as obvious to those skilled in the art, without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
