Micro ovarian tissue biopsy device

Abstract

The present invention relates to the field of medical instruments, in particular to a micro-ovarian tissue biopsy device, comprising: a puncture sleeve, a biopsy forceps rod sleeve, a biopsy forceps rod, a biopsy forceps sleeve, a biopsy forceps, a puncture sleeve seat, a two-way damping sleeve, Auxiliary connector, biopsy forceps rod seat, pressing head, spring. In the micro-ovarian tissue biopsy device of the present invention, the bidirectional damping sleeve inside the biopsy forceps rod seat can not only perform two-way emergency stop and limit the biopsy forceps rod casing, but also ensure internal air tightness, prevent liquid leakage, etc., and ensure The stability of the device during use. The elastic pressing structure at the back end of the sleeve of the biopsy forceps can make the biopsy forceps in a retracted state when there is no external force. Compared with the normal state of the biopsy forceps in the open state, this device can be pulled back and forth to liberate the doctor's hand retraction control , Improve the efficiency of the operation while reducing the physical exertion of the doctor.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a micro-volume ovarian tissue biopsy device. Background technique [0002] Ovarian tumor is a common gynecological tumor. Because the ovary is located in the deep part of the pelvic cavity, it is difficult to find early lesions. Once symptoms appear, they are mostly late, so we should be highly vigilant. The composition of ovarian tissue is very complex, and there are great differences in the histological structure and biological behavior of different types of ovarian tumors. According to histological classification, ovarian tumors are divided into epithelial tumors, germ cell tumors, sex cord stromal tumors, and secondary tumors. According to the nature of the tumor, it is divided into benign, borderline and malignant tumors. [0003] In view of the fact that ovarian tumors are usually asymptomatic in the early stage and the tumor mass is small, they are often discovered occa...

AI Technical Summary

Problems solved by technology

The common methods are multi-point biopsy of ovarian tissue under laparotomy or laparoscopy, and aspirating peritoneal fluid for cytological examination. However, less than 30% of patients with epithelial ovarian cancer are found to have tumors confined to the ovary during surgery, and most of them have spread to the pelvic and abdominal cavity. organs, so early diagnosis is a big problem

[0004] First, ovarian tissue damage is relatively large, and laparotomy or laparoscopic surgery is traumatic. Biopsy forceps are likely to damage the surrounding normal ovarian tissue during ovarian biopsy and affect ovarian function, especially for young patients with fertility requirements.
