Selectable adjustable pudendum expansion device for obstetrical and gynecological operation

Abstract

The invention discloses a selectable pudendum adjustable expansion device for obstetrical and gynecological operations, relates to the technical field of medical instruments, and solves the problems that an existing device is generally of a manual supporting structure, is generally only used for lesion observation, is generally not provided with a structure capable of expanding and supporting in four directions, is poor in supporting and expansion effect, and is inconvenient to use. The problems that an existing device cannot fix an expansion structure for a long time, and a long-time operation is not facilitated are solved. A selectable adjustable pudendum expansion device for obstetrical and gynecological operations comprises a guide rail. The two sides of the top face of the guide rail are fixedly connected with screw holes through casting. The top of the guide rail is fixedly connected with a protruding block through casting. A sliding block is arranged at the top of the guide rail in a sliding connection manner; the top of the sliding block is provided with a control handle in a hinged mode. The curved side surface of the control handle is connected with an expansion control key through a molded surface; by arranging the four sets of electric push rods which are annularly distributed at equal intervals, the controller controls the electric push rods to operate through electric signals, the stainless steel fins expand outwards, expansion supporting in four directions can be achieved, and the supporting effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a selectable adjustable genital dilation device for obstetrics and gynecology operations. Background technique [0002] A vaginal dilator is a tool used by gynecologists to examine a patient's vagina, or uterus. The use of the dilator is to protect the patient's uterus from harm, and it is used to check whether there is any lesion in the patient's vagina, or to check whether there is any similar tumor in the uterus. Some vaginal operations also require this dilator. In vaginal surgery, gynecological duckbill-shaped vaginal dilators have been used to expand the vagina, but the outer opening of the dilator cannot be enlarged or reduced at will. [0003] After retrieval, for example, the patent No. CN106264435A discloses a disposable vaginal dilator, including an upper expansion piece and a lower expansion piece, the upper expansion piece and the lower expansion piece are p...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a selectable genital dilation device for obstetrics and gynecology surgery, to solve the problem that the existing device proposed in the above background technology is generally a manual support structure, and the support fins of the existing vaginal dilator are generally There are two slices up and down, which are generally only used for lesion observation. Generally, there is no structure that can be expanded and supported in four directions, up, down, left, and right. The expansion structure is fixed for a long time. Gynecological surgery generally requires surgery on patients who are in the lying position such as lithotomy. Surgery needs to be performed on the patient's hip, and lighting in the horizontal direction is required. The existing device is not convenient for incisions. Illumination does not provide multi-directional supplementary light, and the line of sight is easily blocked by shadows during the operation, which is not conducive to the problem of long-term operation
