Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to an improved oviduct radiography catheter.
Background
Infertility refers to the fact that the female is not contraception after wedding, and has normal life of a couple, and the female is not pregnant for 1 year. In infertility couples, female factors account for about 60%, while oviduct factors of the important channels and sites for conception account for 20% -40% of female infertility factors. Tubal infertility is one of the major factors responsible for female infertility. Among the treatment methods for infertility caused by oviduct factors, oviduct interventional therapy has been widely used in clinic as a safe, high-success rate, simple-to-operate, atraumatic treatment method, and specific operation methods include selective oviduct radiography (SELECTIVE SALPINGOGRAPHY, SSG), oviduct recanalization (Fallopian tube recanalization, FTR), oviduct embolization (Fallopian tube embolization, FTE).
Selective imaging of the fallopian tube is a necessary procedure, whether it be tubal recanalization or tubal embolization. However, a gap exists between the currently used uterus radiography sheath catheter and the contrast catheter, and after the contrast agent is injected, the pressure in the uterine cavity is large, the contrast agent overflows, the contrast agent in the uterine cavity is poor in filling, the interpretation of the oviduct radiography result is affected, and even a false negative result appears.
Disclosure of utility model
The utility model aims to solve the technical problem of providing an improved oviduct radiography catheter which can effectively solve the problems in the background technology.
In order to solve the problems, the utility model adopts the following technical scheme: the improved oviduct radiography catheter comprises an outer sheath pipe and a connecting pipe, wherein the connecting pipe is communicated with the outer sheath pipe, and is characterized by further comprising an anti-reflux valve and a three-way joint; the outer sheath tube is located at one end far away from the anti-reflux valve and provided with a bending part, and the outer diameter of the bending part gradually expands outwards from the front end to the rear end.
Preferably, the bending angle of the bending part is 20-30 degrees.
Preferably, one end of the outer sheath tube, which is close to the anti-reflux valve, is provided with a fixing wing.
Preferably, the outer diameter of the outer sheath tube is 4mm-6mm, and the length of the outer sheath tube is 130mm-360mm.
Compared with the prior art, the utility model provides an improved oviduct radiography catheter, which has the following beneficial effects:
According to the utility model, by adding the backflow prevention valve at the tail end of the sheath tube, contrast agent backflow can be avoided, and the uterine cavity is filled well; the outer diameter of the bending part on the outer sheath tube gradually expands from the front end to the rear end from small to large, so that the cervical canal is easy to enter the uterine cavity, the spasm of the cervical orifice is reduced, and the stimulation to the cervical canal is reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic view of a part of the structure of the present utility model.
Wherein: 1. the sheath tube is sleeved with the sheath tube 11, the bending part 12, the fixing wing 2, the connecting pipe 3, the anti-reflux valve 4 and the three-way joint.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-2, the utility model provides an improved oviduct radiography catheter, which comprises an outer sheath tube 1 and a connecting tube 2, wherein the connecting tube 2 is communicated with the outer sheath tube 1, and is characterized by further comprising an anti-reflux valve 3 and a three-way joint 4, one end of the outer sheath tube 1 is connected with the anti-reflux valve 3, one end of the connecting tube 2 is connected with the anti-reflux valve 3, and the other end is connected with the three-way joint 4; the outer sheath tube 1 is provided with a bending part 11 at one end far away from the anti-reflux valve 3, and the outer diameter of the bending part 11 gradually expands outwards from the front end to the rear end.
The bent part 11 at the head end of the sheath tube 1 is designed, so that oviduct selection can be better performed.
Preferably, the bending angle of the bending portion 11 is 20-30 degrees;
The bending angle of the bending part 11 is preferably 30 degrees, which accords with most physiological anatomical characteristics of uterine uterus corners, and is convenient for further selective oviduct radiography.
Preferably, a fixing wing 12 is arranged at one end of the outer sheath tube 1 close to the anti-reflux valve 3; after the outer sheath 1 is inserted into the cervical orifice, the fixing wings 12 are fixed on the surgical drape to prevent the outer sheath 1 from falling out and moving.
Preferably, the outer diameter of the outer sheath tube 1 is 4mm-6mm, and the length is 130mm-360mm.
As a specific embodiment of the present utility model:
During selective oviduct radiography operation, firstly, the patient is supine and a bladder lithotomy position is taken; then conventionally disinfecting the vulva and the vagina, and paving a sterile surgical towel; then placing the vaginoscope to expose the external cervical orifice, sterilizing the vagina and cervix; the cervical clamp clamps the cervical to fix the cervical, and the probe probes the uterine cavity position if necessary; finally, after the cervical clamp is fixed at the uterine position, the outer sheath tube 1 is placed at the opening of the uterine horn oviduct, the head end of the outer sheath tube 1 is inserted into the interstitial part of the oviduct under perspective monitoring, and then a contrast agent is injected, and the development condition of the oviduct is observed.
The tail end of the original sheath tube 1 is designed to be open, and contrast agent can be extravasated through a gap between the outer sheath tube and the contrast catheter during contrast, so that the reflux-preventing valve is additionally arranged at the tail end of the sheath tube 1, reflux of the contrast agent is avoided, and the uterine cavity is filled well; contrast observation can be directly carried out by injecting contrast medium through the three-way joint 4 and the connecting pipe 2 without withdrawing a contrast catheter and a guide wire; the outer diameter of the bending part 11 on the outer sheath sleeve is gradually expanded from the front end to the rear end from small to large, so that the cervical canal is easy to enter the uterine cavity, the spasm of the cervical orifice is reduced, and the stimulation to the cervical canal is reduced; the contrast catheter and the guide wire do not need to withdraw the guide wire when in oviduct embolism or recanalization, and the intrauterine condition can be observed through contrast, so that the operation is convenient, the operation time is saved, and the radiation exposure time of a patient is reduced.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
