Medical gynecological examination device with locking mechanism

Abstract

The invention relates to medical instruments, in particular to a medical gynecological examination device with a locking mechanism. The medical gynecological examination device comprises an upper extending arm and a lower extending arm which are mutually hinged, the front end of the upper extending arm and the front end of the lower extending arm are each shaped like a semicircle pipe, a front supporting ring and a rear supporting ring are hinged to the portion between the upper extending arm and the lower extending arm, the front supporting ring and the rear supporting ring are circular ring bodies, the upper ends and the lower ends of the front supporting ring and the rear supporting ring are connected to the inner wall of the upper extending arm and the inner wall of the lower extending arm through shaft seats respectively, and a torsional spring is installed on at least one shaft seat. The gynecological examination device is reasonable in structure, large in expansionary force, balanced in extending arms and not prone to deformation or breaking, the extension state can be automatically locked without operation of external force, and medical staff can conduct examination or operation conveniently.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a medical gynecological examiner with a locking mechanism. 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 ar...

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
