Positioning assembly of fallopian tube interstitial part for PUSH operation

Abstract

The invention discloses a positioning assembly of a fallopian tube interstitial part for a PUSH operation, and belongs to the field of medical apparatuses and instruments, and the PUSH operation is a diffuse uterine lesion focus resection and uterine plasty operation developed by Shenzhen Hospital of Beijing University; the positioning assembly comprises a clamp, a head tube and a metal guide wire; and the front end of the metal guide wire is used for being inserted into a tube cavity of the fallopian tube from the head tube through an opening in the fimbriated extremity of the fallopian tube and then sequentially penetrates through the ampulla, the isthmus and the interstitial part of the fallopian tube to stretch into a uterine cavity, and the clamp is used for clamping the front end of the metal guide wire stretching into the uterus and limiting the metal guide wire from exiting from the uterus. Compared with the prior art, in the PUSH operation, the position of the interstitial part of the fallopian tube can be judged through walking of the metal guide wire, and the situation that the interstitial part of the fallopian tube is accidentally injured when a focus area in a uterine wall muscle layer is cut off is prevented; and the risk of infertility caused by injury of the interstitial part of the fallopian tube in the PUSH operation is reduced and eliminated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a positioning component for the interstitium of the fallopian tube used in PUSH operations. Background technique [0002] Common diffuse uterine lesions include diffuse adenomyosis and diffuse uterine fibroids. Adenomyosis is a diffuse or localized 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 aged 30 to 50, but it can also be seen in young nulliparous women. [0003] Diffuse fibroids are a relatively rare type of uterine fibroids. Its characteristic is: the patient's uterine myometrium is covered with fibroids like pebbles, ranging from dozens to hundreds of fibroids, which are difficult to remove. The conventional operation method for diffuse uterine lesions is to directly remove the entire uterus, but this direct method will cause the p...

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
