Assembly for oviduct intervention recanalization surgery

Abstract

The invention discloses an assembly for an oviduct intervention recanalization surgery. The assembly comprises an outer sleeve and a guide wire arranged in the outer sleeve. The outer sleeve comprises a handheld part, an insertion part and a guide tube head, wherein the handheld part, the insertion part and the guide tube head are sequentially connected from the tail end to the head end. The handheld part comprises a horizontal through tube and an operating handle arranged on the horizontal through tube, the horizontal through tube is a hard tube, the insertion part and the guide tube head are both hoses, the hardness of the guide tube head is smaller than that of the insertion part, and the insertion part comprises a horizontal insertion section and a slant insertion section which are connected. The guide wire comprises a guide wire body and an arc guide head arranged at the front end of the guide wire body, the arc guide head is a soft wire, the guide wire is inserted into the outer sleeve, and the tail end of the guide wire is detachably connected with the tail end of the outer sleeve through a fixing device. Compared with the prior art, the assembly has the advantages that one person can conveniently carry out operation, operation efficiency is improved, surgery time is shortened, and the surgery success rate is increased.

Description

technical field [0001] The invention relates to a medical device, in particular to a kit for interventional recanalization of fallopian tubes. Background technique [0002] With the development of society, the incidence of female infertility is increasing year by year, and tubal factors account for the highest proportion (more than 45%) in female infertility. Abortion, uterine cavity and pelvic inflammation often lead to tubal obstruction, and non-invasive tubal interventional recanalization is an important treatment method. At present, interventional devices for tubal recanalization widely used clinically are generally composed of an overtube, a guide wire, a microcatheter and a microguide wire. The basic operation method is: dilating the vagina with duckbill forceps, exposing the cervix, inserting the overtube into the uterus through the cervix under the guidance of the guide wire, fixing the head of the overtube at the opening of the fallopian tube, withdrawing the guide...

AI Technical Summary

Problems solved by technology

[0003] However, due to the softness of the existing overtube itself, small outer diameter, poor torsion force, and the large space outside the cervix and vagina, the supporting force is insufficient, the overtube is easy to bend, and the guidance of the overtube becomes poor. It often takes repeated operations to successfully insert the outer tube into the opening of the fallopian tube. Multiple operations increase the damage to the endometrium, and in actual operation, at least two people are often needed to cooperate to proceed smoothly. At the same time, the material of the outer tube is Hard plastic, which will cause more pain to the patient when probing into the patient's fallopian tube opening

The head of the current guide wire is designed in a barb shape. The barb-shaped guide wire can effectively prevent blood vessels from being punctured when dredging human blood vessels. When the site is penetrated, the barb-shaped guide wire is easily formed into a circular arc after being blocked, making it difficult to penetrate into a narrower part; and because the head of the guide wire is designed as the barb shape, the guide wire can only be guided from the head of the outer cannula. Insert in the direction of the tail. When the guide is not in place, the guide wire cannot be inserted forward from the tail of the overtube. Instead, the overtube can only be taken out again and inserted into the guide wire, and then reinserted into the patient's uterine cavity. More pain, reduced operation efficiency, and inconvenience

In addition, because tubal interventional recanalization is carried out under the supervision of X-ray equipment, X-rays have certain damage to the human body, so the longer the operation time, it means that patients and doctors will receive more radiation doses
