Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, the current common irrigation mode is to connect an irrigation rod with a medicine supply device and then insert the irrigation rod directly into the vagina to irrigate the vagina. Although the vagina can be flushed to a certain extent by the flushing mode, the problems of vaginal stenosis, vaginal closure and the like caused by local vaginal adhesion and contracture often occur for long-term patients who suffer from cervical cancer radiotherapy, and at the moment, if the flushing rod is forcibly plugged into the vagina, secondary damage can be undoubtedly caused to the vagina, and meanwhile, the vaginal wall of the narrow vagina can be completely attached to the surface of the flushing rod, so that the flushing rod is not beneficial to flushing the vagina.

Implementation mode one

In order to solve the above problem, in one embodiment of the present application, there is provided a gynecological radiotherapy flusher, as shown in fig. 1 and 2, including: the device comprises a shell 1, a sliding sleeve 2, a flushing rod 3, an expansion mechanism 4 and a driving device 5.

In the present embodiment, as shown in fig. 1 and 2, first, the housing 1 includes, in the preset axial direction: a top side 11, a bottom side 12 opposite the top side 11. Next, the housing 1 is provided with a slide 13 from the top side 11 towards the bottom side 12. In addition, as shown in fig. 3, the sliding sleeve 2 includes, around a predetermined axis direction: set up the inner cover body 21 in the slide 13, with the outer jacket body 22 of the coaxial setting of inner cover body 21, connect the annular connecting portion 23 of the inner cover body 21 and outer jacket body 22, and, the whole slidable along predetermineeing the axis direction of sliding sleeve 2, simultaneously, still form between the inner cover body 21 and the outer jacket body 22 and can be by casing 1 male annular 25, and wash excellent 3 along predetermineeing the axis direction and set up in the top of the inner cover body 21, make sliding sleeve 2 when sliding along predetermineeing the axis direction, can drive and wash excellent 3 concerted movement.

In addition, in the present embodiment, as shown in fig. 1 and 2, the expanding mechanism 4 includes: a plurality of supporting petals 41 arranged around the preset axial direction and a connecting rod 42 uniquely corresponding to each supporting petal 41. Wherein each support flap 41 has: a root 411 rotatably connected with the outer casing 22, and a head 412 far away from the root 411, wherein each support petal 41 encloses a containing space 43 capable of containing the flushing rod 3 around the preset axial direction. One end of each link 42 is rotatably connected to the housing 1, and the other end of the link 42 is rotatably connected to the support flap 41.

In addition, in the present embodiment, as shown in fig. 1 and 2, the driving device 5 is connected to the inner sheath 21 of the sliding sleeve 2, so that the driving device 5 can be used to drive the sliding sleeve 2 to slide along the preset axial direction.

In practical applications, when the driving device 5 drives the sliding sleeve 2 to slide along the predetermined axial direction, the outer casing 22 of the sliding sleeve 2 can also synchronously drive the supporting flaps 41 to turn over relative to the washing rod 3. Specifically, when each supporting flap 41 is turned away from the flushing rod 3, as shown in fig. 2, the flushing rod 3 can gradually extend out of the accommodating space 43 along the predetermined axial direction. When the supporting flaps 41 are turned over toward the washing rod 3, as shown in fig. 1, the washing rod 3 can gradually enter the accommodating space 43 along the predetermined axial direction. Meanwhile, as shown in fig. 1 and 2, the outer casing 22 is further provided with a kidney-shaped hole 221 corresponding to each connecting rod 42 along the preset axial direction, and the connecting rod 42 can directly penetrate through the outer casing 22 through the kidney-shaped hole 221, so that the two ends of the connecting rod 42 can be respectively rotatably connected with the casing 1 and the support flaps 41, and the swinging of the connecting rod 42 can be realized through each kidney-shaped hole 221 when each support flap 41 is turned over relative to the wash rod 3, thereby avoiding the blocking phenomenon of the support flaps 41 during the turning over process.

It can be seen from the above that, in practical use, medical staff can drive the sliding sleeve 2 to perform linear motion along the preset axis direction by controlling the driving device 5 through the driving device 5, so that the sliding sleeve 2 can drive each supporting flap 41 of the expanding mechanism 4 to turn over relative to the direction of the flushing rod 3 during motion, and thus each supporting flap 41 can gradually expand the vaginal wall from outside to inside, thereby expanding the narrow space of the vagina. In addition, because each supporting petal 41 is opening the vaginal wall, the rinsing rod 3 can also gradually extend out of the accommodating space 43 enclosed by each supporting petal 41 along the preset axis direction, so that the rinsing rod 3 can not cause damage to the vaginal wall due to local adhesion of the vaginal wall or vaginal stenosis when extending into the accommodating space 43 and entering the vagina, meanwhile, in the rinsing process, because each supporting petal 41 of the expanding mechanism 4 fully expands the vagina, the vaginal wall can be prevented from being attached to the surface of the rinsing rod 3, and the rinsing effect of the rinsing rod 3 on the vagina is better. In addition, as can be easily found from fig. 1, in the process that the supporting petals 41 are turned back towards the position far away from the flushing rod 3, the flushing rod 3 can gradually extend out of the accommodating space 43 under the driving of the sliding sleeve 2, so that when the flushing rod 3 flushes the vaginal wall, the supporting petals 41 cannot interfere with the flushing of the flushing rod 3, and therefore, the flushing effect on the vaginal wall can be further improved.

Specifically, in the present embodiment, as shown in fig. 1 and 2, the supporting petals 41 are formed by bending and extending the entire body from the root 411 to the head 412 in a direction away from the irrigation rod 3, so that the outer surface of the entire supporting petals 41 forms a circular arc curved surface, which ensures that the supporting petals 41 can better adhere to the vaginal wall when the vaginal wall is expanded, and effectively prevents the supporting petals 41 from damaging the vaginal wall when the vaginal wall is expanded. However, as shown in fig. 1 and fig. 2, preferably, the head 412 of each supporting flap 41 is further bent and extended toward the direction of the wash rod 3, so that when each supporting flap 41 is turned to the limit position in the direction toward the wash rod 3, as shown in fig. 2, the head 412 of each supporting flap 41 can be tightly attached to each other, and at this time, the whole accommodating space 43 is a closed space, so that the wash rod 3 can be effectively prevented from being contaminated by foreign matters entering the accommodating space 43.

In addition, it is worth mentioning that in the present embodiment, as shown in fig. 1 and 2, the washing rod 3 is detachably connected to the top of the inner sheath 21, for example: as shown in fig. 3 and 4, the outer surface of the washing rod 3 is provided with an external thread 35, and the top of the inner sleeve 21 is provided with a threaded hole 26, so that the washing rod 3 and the inner sleeve 21 can be connected by threads, thereby ensuring that the washing rod 3 in the embodiment can be replaced at any time, avoiding cross infection and adopting different types of washing rods 3 according to the requirements of different patients. For example, the present embodiment can use the irrigation rod 3 with different outer diameters to irrigate the vaginal wall according to the different vaginal dilation degrees. For example, the irrigation rod 3 may comprise a threaded section and a body section coaxially connected to the threaded section, wherein the threaded section is of a standard size to be threadedly connected to the threaded hole 26 at the top of the inner sheath 21, and the outer diameter of the body section may have various sizes depending on the degree of dilation of the vaginal wall. Alternatively, the flushing rod 3 can also adopt flushing rods 3 with different flushing hole structures to flush the vaginal wall according to different flushing requirements. For example, in some embodiments, the structure of the wash rod 3 is as shown in fig. 4, the wash rod 3 has an inner surface 31 and an outer surface 32 opposite to the inner surface 31 around a predetermined axis direction, wherein the inner surface 31 surrounds and forms a spray channel 33 around the predetermined axis direction, and a plurality of wash holes 34 communicating with the spray channel 33 are distributed in the direction from the outer surface 32 to the inner surface 31 of the wash rod 3, each wash hole 34 is distributed in an equidistantly surrounding manner along the predetermined axis direction, and the axis of each wash hole 34 forms an angle with the predetermined axis. However, as a preferred embodiment, the included angle between the axis of each circle of the irrigation holes 34 arranged around and the preset axis is different, for example, as shown in fig. 4, the included angle between the axis of each circle of the irrigation holes 34 arranged around and the preset axis is gradually increased from top to bottom, so that the irrigation rod 3 can perform no dead angle irrigation on the vaginal wall, and the irrigation effect of the irrigation rod 3 on the vaginal wall is further improved. However, it should be noted that, in the practical application, the included angle between the axis of each flushing hole 34 and the preset axis may be the same, and this is not particularly limited in this embodiment. In addition, it should be noted that the aperture of each flushing hole 34 can be completely different, for example, the aperture of each circle of flushing holes 34 is gradually increased towards the direction away from the inner sheath 21, so that the flow rate of each flushing hole 34 close to the inner sheath 21 is substantially the same as the flow rate of each flushing hole 34 away from the inner sheath 21, thereby further improving the flushing effect of the flushing rod 3 on the vaginal wall.

In addition, in order to enable the driving device 5 to drive the sliding sleeve 2 to perform linear motion along the preset axial direction, in the present embodiment, as shown in fig. 5, the housing 1 is opened with an insertion hole 14 communicating with the slideway 13 from the bottom side 12 to the top side 11 along the preset axial direction, and the inner diameter of the insertion hole 14 is smaller than that of the slideway 13, so that a supporting surface (not shown) abutting against the inner sleeve body 21 is formed between the slideway 13 and the insertion hole 14. Meanwhile, as shown in fig. 1 and 2, the driving device 5 includes: a transmission rod 51, a driven gear 52, a driving gear 53 and a motor 54. As shown in fig. 5, the driving rod 51 sequentially includes, along the preset axis direction: a threaded section 511 arranged in the slideway 13, a smooth section 512 arranged in the insertion hole 14, and a part of the smooth section 512 penetrates out of the bottom side 12 of the shell 1 and is exposed outside the shell 1. In addition, the driven gear 52 is coaxially connected with the smooth section 512 and meshed with the driving gear 53, and simultaneously, the main shaft of the motor 54 is coaxially fixed with the driving gear 53. In addition, it should be noted that the inner side wall surface of the inner sleeve 21 is provided with an internal thread (not shown) screwed with the threaded section 511 of the transmission rod 51, and the outer sleeve 22 is slidably connected with the housing 1 along a predetermined axial direction.

It will be understood that in practical applications, as shown in fig. 1 and 2, the driving gear 53 and, therefore, the driven gear 52 may be driven by the motor 54 to rotate, and the driven gear 52 may be driven to rotate, while the driving gear 51 may follow the driven gear 52 to rotate synchronously by virtue of the coaxial connection with the smooth section 512 of the driving rod 51. In addition, since the inner sleeve 21 of the sliding sleeve 2 is connected with the threaded section 511 of the transmission rod 51 in a threaded manner, and meanwhile, the outer sleeve 22 of the sliding sleeve 2 is connected with the housing 1 in a sliding manner along the preset axial direction, when the transmission rod 51 rotates, as shown in the combination 5, the sliding sleeve 2 can change the rotation motion of the transmission rod 51 into a linear sliding motion along the preset axial direction, so that the flushing rod 3 can extend out of or enter the accommodating space 43 under the sliding action of the sliding sleeve 2. Meanwhile, each supporting flap 41 can also be turned over relative to the irrigation rod under the sliding action of the sliding sleeve 2 by taking the connecting end of the root 411 and the outer sleeve 22 as a pivot point and under the supporting and limiting action of the connecting rod 42, so as to realize the supporting and expanding of the vaginal wall.

Moreover, it should be noted that, in the present embodiment, in order to enable the outer sleeve 22 of the sliding sleeve 2 to be slidably connected with the housing 1, as shown in fig. 3, a plurality of sliding slots 15 are distributed on the outer surface of the housing 1 along the preset axial direction, and at the same time, a plurality of sliding blocks 24 are further disposed on the inner side wall surface of the outer sleeve 22, and the number of the sliding blocks 24 is the same as the number of the sliding slots 15 and uniquely corresponds to the number of the sliding slots 15, and each sliding block 24 is respectively embedded into the uniquely corresponding sliding slot 15, so that each sliding block 24 can slide along the length direction of the uniquely corresponding sliding slot 15, thereby it is not difficult to see that, in combination with fig. 5, when the transmission rod 51 rotates, the sliding sleeve 2 can effectively avoid the rotational movement of the sliding sleeve 2, so that the sliding sleeve 2 at this time can slide only along the preset axial direction by means of the threaded engagement with the threaded section 511 of the transmission rod 51, thereby achieving the up-and-down movement of the rinse rod 3.

Meanwhile, it is worth noting that in order to avoid friction between the transmission rod 51 and the housing 1 when the transmission rod 51 rotates, as shown in fig. 5, the bearing sleeves 6 are respectively arranged at two ends of the insertion hole 14 along the preset axial direction, the outer ring 61 of the bearing sleeve 6 is fixedly connected with the housing 1, the inner ring 62 of the bearing sleeve 6 is fixedly connected with the transmission rod 51, the transmission rod 51 can be prevented from being in hard contact with the housing 1 when the transmission rod 51 rotates through the bearing sleeves 6, and the rotation performance of the transmission rod 51 is improved while the friction coefficient is reduced. In addition, as a preferable aspect, the radiotherapy flusher for gynecology of the present embodiment further includes: the torque sensor is used for detecting the torque of the motor, and meanwhile, as shown in fig. 6, the torque sensor and the motor 54 are both in communication connection with the remote terminal, and the remote terminal is used for acquiring a torque value detected by the torque sensor and controlling the motor 54 in real time according to the acquired torque value. For example, when the vagina of the patient is gradually expanded by each supporting flap 41, the counterforce exerted on each supporting flap 41 by the vaginal wall is gradually increased, and then the torque of the motor 54 is increased, so as to avoid the transition expansion of the vagina by each supporting flap 41 and prevent the vaginal wall from being torn, the medical staff can firstly use the remote terminal to set the torque value of the motor 54, and when the torque value acquired by the remote terminal reaches the preset value, the motor 54 is controlled to stop working, so that the vaginal wall of the patient can be protected from being torn while the vagina is expanded.

In addition, as shown in fig. 1, 2 and 5, the transmission rod 51 is further provided with a channel 513 communicating with the slideway along the preset axial direction, and the gynecological radiotherapy flusher of the present embodiment further includes: a water supply pipe 7 and a water passing connecting piece 8. Wherein the water supply pipe 7 is inserted into the passage 513 in a preset axial direction, and the water supply pipe 7 has: the water supply device comprises a water inlet end 71 and a water outlet end 72 opposite to the water inlet end 71, meanwhile, the water supply pipe 7 and the transmission rod 51 can rotate relative to each other around the direction of a preset axis, and in order to realize the relative rotation of the water supply pipe 7 and the transmission rod 51, a matching mode similar to that between the transmission rod 51 and the shell 1 can be adopted between the water supply pipe 7 and the transmission rod 51, specifically, as shown in fig. 5, bearing sleeves 9 for fixing the water supply pipe 7 are respectively arranged at two ends of a channel 513 of the transmission rod 51 along the direction of the preset axis, an outer ring 91 of each bearing sleeve 9 is fixedly connected with the inner side wall surface of the transmission rod 51, an inner ring 92 of each bearing sleeve 9 is fixedly connected with the water supply pipe 7, and the transmission rod 51 can be prevented from being in hard contact with the water supply pipe 7 during rotation through the bearing sleeves 9, so that the phenomenon that the water supply pipe 7 is prevented from being twisted effectively. In addition, in the present embodiment, as shown in fig. 1 and 2, the water passing connector 8 includes: a flexible tube 81, a first connecting piece 82 arranged at one end of the flexible tube 81, and a second connecting piece 83 arranged at the other end of the flexible tube 81, wherein the first connecting piece 82 is connected with the water inlet side 811 of the flexible tube 81, and the second connecting piece 83 is connected with the water inlet side of the flushing rod 3. Therefore, in practical application, the water inlet end 71 of the water supply pipe 7 can be externally connected with a medicine supply device, so that the medicine supply device can supply medicine liquid into the flushing rod 3 through the flexible pipe 81 by means of the water supply pipe 7, and flushing of the flushing rod 3 on the vaginal wall is realized. And, when the sliding sleeve 2 drives the flushing rod 3 to do linear motion along the preset axis direction, the flexible pipe 81 can also realize stretching in different degrees according to the motion position of the flushing rod 3, and the motion of the flushing rod 3 cannot be influenced while the medicine supply is ensured. In this embodiment, the flexible tube 81 may be a spring tube, and the flexible tube may satisfy the requirement that the flushing rod 3 is freely stretched during movement due to the telescopic property of the spring tube.

The second embodiment of the present application provides a gynecological radiation therapy irrigator, which is a further improvement on the basis of the first embodiment, and the main improvement thereof is that, when the vaginal of a patient is irrigated, the radiotherapy irrigator of the present embodiment needs to be realized by means of the support expansion of the support petals 41 on the vaginal wall, so that the support petals 41 must be always attached to the vaginal wall, which inevitably causes the secretion on the vaginal wall to be attached to the support petals 41, and in order to avoid cross infection of the irrigator during use, the use cost of the irrigator can be reduced, as shown in fig. 7, the gynecological radiation therapy irrigator of the present embodiment further comprises: a stop ring 10 detachably arranged on the top side 11 of the housing 1, and each sliding slot 15 on the housing 1 is unclosed on the top side 11 of the housing 1, i.e. each sliding slot 15 directly penetrates the top side 11 of the housing 1. Meanwhile, the detachable connection mode can be adopted between one end of the connecting rod 42 rotatably connected with the supporting valve 41 and the supporting valve 41.

Specifically, in the present embodiment, in order to realize the detachable connection of the limiting ring 10 and the housing 1, as shown in fig. 7 and 8, a part of the top side 11 of the housing 1 protrudes along the predetermined axial direction to form an external thread section 16, and at the same time, the inner surface of the limiting ring 10 is provided with an internal thread section 101 screwed with the external thread section 16, the limiting ring 10 can be fixed on the top side 11 of the housing 1 by the threaded engagement of the internal thread section 101 of the limiting ring 10 and the external thread section 16 of the housing 1, the sliding distance of the sliding sleeve 2 can be limited by the limiting ring 10, and the sliding sleeve 2 is prevented from being separated from the transmission rod 51 when sliding.

In addition, in order to realize the detachable connection between the connecting rod 42 and the supporting petals 41, as shown in fig. 9, a shaft body 44 may be embedded in the inner side surface of each supporting petal 41, and a sleeve 46 rotatably connected with the shaft body 44 is disposed at one end of the connecting rod 42 rotatably connected with the supporting petal 41, so that the connecting rod 43 can be reversely rotated by taking the axis of the sleeve 46 as a pivot axis, and at the same time, the sleeve 46 and the connecting rod 42 are directly detachably connected, for example: and is screwed so that the sleeve 46 can be detached from the connecting rod 42, thereby achieving the detachable connection between the connecting rod 42 and the support flap 41. Note that, the separation between the boss 46 and the link 42 is avoided. As shown in fig. 9, the bushing 46 in the present embodiment includes: the main sleeve 461 rotatably connected to the shaft 44 and the sub-sleeve 462 threadedly connected to the link 42 are coaxially disposed, and the sub-sleeve 462 and the main sleeve 461 are rotatably connected in the coaxial direction, so that when the sub-sleeve 462 is released from the threaded connection with the link 44, the main sleeve 461 does not interfere with the rotation of the sub-sleeve 462.

Therefore, it is easy to see that, since the connection between each link 42 and each support flap 41 and the connection between the stop collar 10 and the housing 1 are detachable, when the stop collar 10 is removed from the top side 11 of the housing 1, the sliding sleeve 2 can be driven by the transmission rod 51, and by means of the sliding fit between each sliding block 24 and each sliding slot 15 on the housing 1, the sliding sleeve 2 can be detached from the top side of the housing 1, and after the sliding sleeve 2 is detached, the connection relationship between each link 42 and the shaft sleeve 46 is released, so that the whole sliding sleeve 2 and each support flap 41 can be directly detached from the top side of the housing 1, thereby realizing the replacement of each support flap 41, and therefore, the radiotherapy flusher of the present embodiment can avoid cross infection during use, and can also reduce the use cost of the flusher.

In addition, because each support flap 41 can be removed from the housing through the sliding sleeve 2, in practical application, the sliding sleeve 2 and each support flap 41 can be taken as an independent module, so that in the present embodiment, the support flaps 41 can have different structural characteristics according to practical use requirements, so as to meet the expansion requirements of different patients. For example, the curvature of the arc of the outer surface of the expansion lobes 41 can be of various types to meet different expansion requirements.

Moreover, as a preferable scheme, a protective layer (not shown) may be further disposed on the outer surface of each supporting flap 41, and the protective layer is made of a flexible skin-friendly material, so that when each supporting flap 41 supports and expands the vaginal wall, discomfort of the patient can be greatly reduced.

Third embodiment

The third embodiment of the present application provides a gynecological radiotherapy flusher, which is a further improvement on the first and second embodiments, and the main improvement is that, as shown in fig. 10, the gynecological radiotherapy flusher of the present embodiment further includes: the flexible expansion sheet 20, and as shown in fig. 12, the flexible expansion sheet 20 has, around a predetermined axial direction: lateral side 201, and medial side 202 opposite lateral side 201. Wherein, the inner side ring 202 of the flexible expansion sheet 20 is sleeved on the outer casing 22 of the sliding sleeve 2 and is fixedly connected with the outer surface of the outer casing 22, and meanwhile, the outer side 201 of the flexible expansion sheet 20 is fixedly connected with the inner surface of each supporting flap 41.

In actual use, when each supporting flap 41 is turned away from the flushing rod 3, as shown in fig. 11, the flexible expansion sheet 20 is pulled by each supporting flap 41 and can be gradually expanded by each supporting flap 41. When the supporting flaps 41 are turned in the direction of the wash rod 3, as shown in fig. 10, the flexible expansion sheet 20 is less pulled by the supporting flaps 41, so that it can be gradually contracted.

It can be seen from the above that, after the supporting flaps 41 complete the vaginal dilation, the flexible dilation sheet 20 can be stretched to approximate to an annular structure, and at this time, most of the liquid medicine ejected from the washing rod 3 can not directly flow out of the vagina after the vaginal wall is washed, but can be blocked by the flexible dilation sheet 20, so that the liquid medicine stays on the upper surface of the flexible dilation sheet 20, thereby effectively prolonging the contact time between the liquid medicine and the vaginal wall, enabling the medicine to better penetrate into the vaginal wall, and further improving the washing effect on the vaginal wall.

Specifically, in the present embodiment, as shown in fig. 10, 11 and 12, the flexible expansion sheet 20 has a plurality of annular folded portions 203 connected in series in the direction from the outer side surface 201 to the inner side surface 202, so that when the support flaps 41 are turned in the direction away from the wash rod 3, the annular folded portions 203 of the flexible expansion sheet 20 are sequentially folded open, so that the entire flexible expansion sheet 20 can be gradually extended as shown in fig. 11. When the supporting flaps 41 are turned toward the direction of the washing rod 3, the annular folded portions 203 of the flexible expansion sheet 20 are sequentially overlapped, as shown in fig. 10, so that the entire flexible expansion sheet 20 can be gradually contracted.

In addition, it should be noted that, when each supporting flap 41 and the sliding sleeve 2 are taken as a separate module, it is preferable that a part of the flexible expansion piece 20 is covered on the top side of the outer casing 22 from the inner side surface 202 to the outer side surface 201 of the flexible expansion piece 20, and the flexible expansion piece 20 and the top side of the outer casing 22 are locked and fixed by the locking member, so that the flexible expansion piece 20 and the outer casing 22 can be fixed by adopting a detachable connection manner, therefore, when the supporting flaps 41 need to be replaced, the flexible expansion piece 20 can be connected with each supporting flap 41 and removed from the top side 11 of the housing 1 together, thereby realizing the replacement of the flexible expansion piece 20.

Finally, it should be noted that those skilled in the art will appreciate that embodiments of the present application present many technical details for the purpose of enabling the reader to better understand the present application. However, the technical solutions claimed in the claims of the present application can be basically implemented without these technical details and various changes and modifications based on the above-described embodiments. Accordingly, in actual practice, various changes in form and detail may be made to the above-described embodiments without departing from the spirit and scope of the present application.
