Pneumoperitoneum-free transvaginal laparoscopic surgery vaginal fornix incision expanding, fixing and exposing device

Abstract

The invention discloses a pneumoperitoneum-free transvaginal laparoscopic surgery vaginal fornix incision expanding, fixing and exposing device which comprises an inner ring, a connecting rod and an outer ring, the inner ring and the outer ring are made of shape memory alloy, the inner ring and the outer ring are in a semi-wrinkled ring shape in a low-temperature static state, and the corresponding positions of the inner ring and the outer ring are connected through a plurality of pull rods, an inner ring and outer ring semi-corrugated cylinder grid shape is formed, the memory state starts to be recovered when the temperature is above 30 DEG C, and the memory state is completely recovered when the temperature is close to the temperature of a human body, so that an expanded cylindrical grid structure is formed. The device can well assist in completing pneumoperitoneum-free transvaginal laparoscopic surgery and has the advantages of being simple in structure, convenient to use, low.

Description

technical field [0001] The invention relates to a gynecological medical instrument, in particular to a pneumoperitoneum-free transvaginal laparoscopic surgery vaginal fornix incision expansion and fixation revealer with memory function. Background technique [0002] With the development of laparoscopic minimally invasive technology, many benefits have been brought to patients, from conventional transabdominal multi-hole to transumbilical single-hole, and then to transvaginal gynecological laparoscopic surgery; from minimally invasive abdominal multiple small incisions to minimally invasive Single hidden incision through the umbilicus, and then minimally invasive transvaginal abdominal incision, less surgical trauma and pain, faster recovery. Transvaginal gynecological laparoscopic surgery can solve the problems of conventional transvaginal gynecological surgery, such as small field of view, inability to explore the upper abdomen, inability to separate pelvic-abdominal adhesi...

AI Technical Summary

Problems solved by technology

Due to the use of CO2 gas in pneumoperitoneum, postoperative complications such as shoulder, back and chest pain, subcutaneous emphysema, etc. may occur, and it will have a certain impact on cardiopulmonary function, so some elderly patients or patients with poor cardiopulmonary function should use this type of minimally invasive surgery with caution. To some extent, the scope of application of this type of operation is limited

In response to the above problems, some scholars have begun to try pneumoperitoneum-free transvaginal laparoscopic gynecological surgery. So far, there is still a lack of special supporting medical devices for the expansion and fixation of vaginal vault incisions in pneumoperitoneum-free transvaginal laparoscopic surgery.
