Self-locking gynecologic examination device

Abstract

The invention relates to medical instruments, particularly to a self-locking gynecologic examination device. The self-locking gynecologic examination device comprises an upper extending supporting arm and a lower extending supporting arm, the upper extending supporting arm and the lower extending supporting arm are hinged together, the front ends of the upper extending supporting arm and the lower extending supporting arm are in the shape of a semicircle tube, a front supporting ring and a rear supporting ring are hinged between the upper extending supporting arm and the lower extending supporting arm, the front supporting ring and the rear supporting ring are ring-shaped bodies, the upper ends and the rear ends of the front supporting ring and the rear supporting ring are respectively connected onto the inner wall of the upper extending supporting arm and the lower extending supporting arm through shaft seats, and torsional springs are arranged on at least one shaft seat. The self-locking gynecologic examination device is reasonable in structure, large in expansionary force, balanced in extending supporting arms, not easy to be distorted or broken and capable of being locked in an expansionary state automatically without external force operation and facilitating examination or operation of medical staff.

Description

technical field [0001] The invention relates to a medical device, in particular to a self-locking gynecological examination device. Background technique [0002] The gynecological examination device is also called endoscope, which is a commonly used medical device in obstetrics and gynecology. The existing duckbill endoscope is mainly composed of upper and lower semicircular expansion arms. By pressing the handle, the expansion arm expands. Open for easy observation of internal lesions. This kind of endoscope cannot lock the position of the expansion arm when in use, must be pressed on the handle with hand all the time, can't use other inspection or treatment instruments simultaneously, and operation is inconvenient. Chinese patent 2012204694925 discloses a "Gynecological Examiner with a Locking Mechanism", the main structure of which is still composed of an expansion arm and a handle, but a fastening bolt is arranged on the hinge shaft between the expansion arm and the han...

AI Technical Summary

Problems solved by technology

However, in actual use, it is found that the handle-type expansion mechanism is laborious to expand, the wall thickness of the expansion arm is small, and it is easy to deform or even break; the expansion resistance is large, and the resilience is also large, and the smaller bolts cannot achieve the purpose of locking. Larger bolts take up a lot of space and easily obstruct observation
