Vaginal dilator for gynecological operation

Abstract

The vaginal dilation instrument comprises vaginal dilation pieces and a limiting frame, the vaginal dilation pieces are movably installed on the two sides of the interior of the limiting frame, fixing blocks are slidably installed on the inner sides of the vaginal dilation pieces, angle transmission mechanisms are fixedly installed at the bottoms of the back faces of the fixing blocks, and shaft pins are movably installed on one sides of the fixing blocks; a sleeve block is fixedly mounted on the surface of the shaft pin, and a supporting rod is fixedly connected to the side, away from the fixing block, of the sleeve block. The vaginal dilator can combine structures to facilitate observation and can assist in vaginal dilation piece inner cavity operation so as to solve the problems that most structures of an existing vaginal dilator are concentrated at an opening, the sight lines of many medical workers are affected, meanwhile, the surgical operation convenience of doctors is affected, the hand operable space is narrower, an inner cavity auxiliary operation structure is not arranged, and operation is inconvenient. In the operation process, the body position of a doctor is limited, and personnel participating in the operation are limited, so that the operation intensity is increased, and the operation efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of vaginal expanders, in particular to a vaginal expander for gynecological surgery. Background technique [0002] In gynecological surgery, there will be vaginal dilation. The currently commonly used vaginal dilator, similar to the duckbill, first requires magic lubricant during operation, and then the doctor slowly pushes the vaginal dilator into the vagina and maintains the vaginal dilator in an open state for surgical operation. [0003] In the prior art, the structure of the vaginal expander is mostly concentrated at the opening, which affects the sight of many medical staff, and at the same time affects the convenience of the doctor's surgical operation, making the operating space of the hand narrower, and does not have the ability to assist the operation of the inner cavity. Due to the structure, the doctor's position is limited during the operation, and the number of personnel who can participate in...
