Uterine lifter

Abstract

The invention provides a uterine lifter. The uterine lifter comprises the following parts: a lifting pad which is feasible for slight deformation, a frame which is fixed on the whole circumferential edge of the lifting pad, and a plurality of rings which are arranged on the frame. The uterine lifter is curable, and can automatically expand from curled state to tile state without external force. The uterine lifter provided by the scheme is capable of performing effective fixing and lifting on the uterine during operation, so that visual fields of the rectum and the like can be exposed so as tohave pelvic operation space expanded; and thus, the operation is facilitated. Moreover, the uterine lifter can be curled, so that entering of the uterine lifter into the abdominal cavity in a relatively small volume is allowed; and the uterine lifter can automatically expand after being placed into the abdominal cavity, so that the uterine lifter is relatively large in lifting area and capable ofof performing more complete lifting on the uterine so as to protect the uterine from shear stress damage during lifting process as well as prevent the uterine from falling during the lifting process.In addition, the structure is capable of fixing the uterine at any suitable height by lifting rings, such as surgical line in vitro and the like, so that fixing height of the uterine becomes more convenient and flexible.

Description

technical field [0001] Embodiments of the present disclosure generally relate to auxiliary instruments in female bowel operations, and more specifically, relate to a uterine lifter for lifting a female uterus during operations. Background technique [0002] Rectal cancer, located between the sigmoid-colorectal junction and the dentate line, is one of the common malignant tumors of the digestive tract. In 2013, the incidence rate of male rectal cancer in my country ranked 4th among malignant tumors, and the mortality rate ranked 5th, while the incidence rate of female rectal cancer ranked 3rd, and the mortality rate ranked 4th. Laparotomy has always been the main method for the treatment of rectal cancer. In recent years, laparoscopic rectal cancer surgery has developed rapidly due to its small damage and fast recovery. Laparoscopic surgery has the characteristics of less trauma and faster recovery. The use of ultrasonic scalpel effectively reduces intraoperative blood loss....

AI Technical Summary

Problems solved by technology

However, due to the small operating space in the female pelvis, the position of the uterus often affects the field of view under the laparoscope, and affects the dissociation of blood vessels and lymph node dissection during the operation.
