Microscale ovarian tissue biopsy device

Abstract

The invention relates to the field of medical instruments, in particular to a microscale ovarian tissue biopsy device. The microscale ovarian tissue biopsy device comprises a puncture cannula, a biopsy forceps rod cannula, a biopsy forceps rod, a biopsy forceps cannula, biopsy forceps, a puncture cannula seat, a bidirectional damping sleeve, an auxiliary connector, a biopsy forceps rod seat, a pressing head and a spring. According to the microscale ovarian tissue biopsy device, the bidirectional damping sleeve in the biopsy forceps rod seat can perform bidirectional sudden stop limiting on the biopsy forceps rod cannula, the internal air tightness can also be ensured, the situations of liquid leakage and the like are prevented, and the stability of the device in the using process is ensured. An elastic pressing structure at the rear end of the biopsy forceps rod cannula can enable the biopsy forceps to be in a folded state without external force, compared with a conventional state that the biopsy forceps are in an open state, the device can be pulled back and forth so that hand folding control of a doctor can be liberated conveniently, the operation efficiency is improved, and meanwhile physical output of the doctor is reduced.

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.
