The fallopian tube directional catheter of the present utility model is described below in connection with fig. 1-4.
As shown in FIG. 1, in one embodiment, a qualitative tubal catheter includes a main catheter 110, a guide post 120, and a branch catheter 130.
The main conduit 110 has an axially extending liquid flow passage.
Specifically, the main conduit 110 is a hollow conduit, and the hollow space is a liquid flow channel.
The guide post 120 is disposed at the top of the main guide tube 110 along the axial direction of the main guide tube 110.
Specifically, the guide post 120 is smoothly connected to the main guide tube 110, and may be integrally formed. The top of the guide post 120 is round and may be hemispherical.
The branch conduit 130 has a liquid passage, one end of which is connected to the top of the main conduit 110, and the other end of which extends in a curved manner away from the guide post 120.
Wherein, the liquid channel of the branch conduit 130 is communicated with the liquid channel of the main conduit 110, and the length of the branch conduit 130 is longer than that of the guide post 120. The branch duct 130 is a flexible tube such as a rubber tube.
Specifically, the lengths of the guide post 120 and the branch guide tube 130, and the angle between the branch guide tube after bending and extending and the guide post 120 are set according to the positional relationship between the bottom of the female uterine cavity and the oviduct opening.
After the oviduct directional catheter of the embodiment stretches into the uterine cavity, the bottom of the guide pillar 120 is propped against the uterine bottom, and the main catheter 110 is rotated to finely adjust the branch catheter 130, so that the branch catheter 130 stretches into the oviduct, the operation is simple, the success rate is high, more discomfort brought to a patient by multiple attempts is avoided, and the operation difficulty of doctors is reduced.
As shown in fig. 2, in one embodiment, the oviduct directional catheter further includes a telescopic balloon 140, the telescopic balloon 140 is wrapped on the wall of the end of the branch catheter 130 far away from the main catheter 110, and the telescopic balloon 140 is connected with an air path, and the air path extends to the bottom of the main catheter 110.
Specifically, in the process of extending into the uterine cavity, the telescopic airbag 140 is in a contracted state, when the top of the guide pillar 120 is abutted against the uterine bottom and the branch catheter 130 extends into the uterine tube, the telescopic airbag 140 is inflated and swelled through the air passage ventilation, the inflated telescopic airbag 140 is matched with the guide pillar 120 to enable the branch catheter 130 to be more stable and not to move, and meanwhile, in the process of delivering liquid to the uterine tube, the backflow of the liquid can be prevented, as shown in fig. 4. The normal saline with bubbles can be directionally conveyed, so that the smoothness of the oviduct can be monitored by ultrasound, and sperms can be directionally conveyed, so that the fertilized implantation of the ovum is facilitated.
In this embodiment, the cross-sectional area of the telescoping balloon 140 near the free end of the branch catheter 130 is less than the maximum cross-sectional area of the balloon. The bellows 140 is transparent. The shape of the telescopic air bag can be designed according to the shape of the junction of the oviduct and the uterine cavity, so that the front end of the telescopic air bag 140 stretches into the oviduct more, the rear section blocks the oviduct, the branch guide pipe 130 can be more stable, and the branch guide pipe is not easy to move in the process of conveying liquid. The oviduct directional catheter of this embodiment can also inflate and expand the telescopic airbag 140 after stretching into the uterine cavity, on the one hand, the inflated telescopic airbag 140 improves the comfort level in the process of searching for the oviduct opening, on the other hand, the shape design of the telescopic airbag 140 can also play a certain guiding role, which is helpful for more rapidly searching for the oviduct opening.
In this embodiment, the main conduit 110 includes an inner tube 112 and an outer tube 114 with a gap between the inner tube 112 and the outer tube 114. The guide post 120 is attached to the top of the outer tube 114 and the inner tube 112 is attached to the branch tube 130. The liquid flow passage extends along the axial direction of the inner tube 112 to communicate with the liquid passage of the branch duct 130, and the gas path extends to the bottom of the main duct 110 via the gap.
The branch catheter 130 is sleeved with an air duct 150, one end of the air duct 150 is connected with the telescopic air bag 140, and the other end is connected with the outer tube 114. The liquid flow channel of the inner tube 112 and the liquid channel of the branch conduit 130 are used for flowing when liquid is injected, and are mutually independent and not interfered with the air channel formed by the telescopic air bag 140, the air duct 150 and the outer tube 114.
As shown in fig. 3, in one embodiment, the end of the main conduit 110 facing away from the guide post 120 has a plurality of graduations 160. The end of the main conduit 110 facing away from the guide post 120 is sleeved with a measuring ring 170 which can slide along the wall of the main conduit 110.
Specifically, the graduation marks 160 are marked with the top end of the guide post as zero graduation, and when the guide post extends to the bottom of the uterine cavity, the measuring ring 170 moves to a corresponding position by the resistance of the outer side of the uterine cavity, so that the depth of the uterine cavity is measured, and the depth is shown in fig. 4.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
