Locating assembly for tubal interstitium for push surgery

Abstract

The invention discloses a positioning assembly for the interstitial part of the fallopian tube provided by the invention for PUSH operation, which belongs to the field of medical devices. The PUSH operation is a diffuse uterine lesion excision and hysteroplasty operation developed by Peking University Shenzhen Hospital; It includes a clip, a head tube and a metal guide wire; the front end of the metal guide wire is used to insert the head tube into the fallopian tube lumen through the opening of the umbrella end of the fallopian tube, and then pass through the ampulla, isthmus, and interstitial lumen of the fallopian tube in turn. Into the uterine cavity, the clip is used to clamp the front end of the metal guide wire extending into the uterus to restrict the metal guide wire from exiting the uterus; It can prevent accidental injury to the interstitial part of the fallopian tube when the lesion area in the myometrium of the uterine wall is removed; reduce and eliminate the risk of infertility caused by damage to the interstitial part of the fallopian tube during PUSH operation.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a positioning assembly for the interstitial part of fallopian tubes for PUSH operation. Background technique [0002] Common diffuse uterine lesions include diffuse adenomyosis and diffuse uterine fibroids. Adenomyosis is a diffuse or limited lesion in which endometrial glands and stroma invade the myometrium. Like endometriosis, it is a common and difficult disease in gynecology. Adenomyosis mostly occurs in multiparous women between the ages of 30 and 50, but it can also be seen in young nulliparous women. [0003] Diffuse fibroids are a rare type of uterine fibroids. Its characteristics are: the myometrium of the patient is covered with fibroids like pebbles, the number ranging from dozens to hundreds, which is difficult to remove. The conventional surgical method for diffuse uterine lesions is to directly remove the entire uterus, but this direct removal method will make...

AI Technical Summary

Problems solved by technology

The conventional operation method for diffuse uterine lesions is to directly remove the entire uterus, but this direct method will cause the patient to be infertile; then there is a birth-preserving PUSH operation, and the PUSH operation is performed by Peking University Shenzhen Hospital (PekingUniversity Shenzhen Hospital, PUSH) developed diffuse uterine lesion resection and hysteroplasty surgery, which does not need to remove the patient's uterus; only the myometrium of the uterine wall and diffuse lesions are completely removed; the patient still has fertility after surgery

[0004] During the operation, it is necessary to cut the uterus and remove the myometrial lesion area of ​​the uterine wall; however, the interstitial part of the fallopian tube is the part of the fallopian tube running in the myometrium of the uterine wall, so it is easy to accidentally injure or Cut off the interstitial part of the fallopian tube, resulting in truncation between the fallopian tube and the uterine cavity, resulting in tubal infertility after surgery
