Vagina snooping instrument for gynaecology and obstetrics examination

Abstract

The invention discloses a vagina snooping instrument for gynaecology and obstetrics examination, and belongs to the technical field of gynaecology and obstetrics instruments. The vagina snooping instrument for gynaecology and obstetrics examination comprises an expansion tube in a hollow column shape, the top end of the expansion tube is provided with an insertion end, and the insertion end is provided with an arc-shaped surface. When a fish-eye lens is moved left and right, shifting pieces on the left side and the right side are operated, rotating blocks at the two ends of a rotating rod rotate in a hollow cylindrical sleeve, a torsion spring generates elasticity, and therefore, it can be guaranteed that the fish-eye lens on a matched sliding block rotates transversely. Then, the fish-eye lens rotates by 270 degrees towards the two sides with the top of the vagina inner cavity as the middle point, and it can be guaranteed that the vagina inner cavity is comprehensively scanned. The fish-eye lens is adjusted in four directions, it can be guaranteed that the fish-eye lens achieves comprehensive detection on one station, the detection range is ensured, and the detection efficiency can be improved. The detection operation can be realized without externally adjusting the position of the fish-eye lens, and the problem of uncomfortable feeling generated in the existing detection process is solved.

Description

technical field [0001] The invention belongs to the technical field of obstetrics and gynecology instruments, in particular to a vaginal speculum instrument for obstetrics and gynecology examinations. Background technique [0002] The vaginal speculum for obstetrics and gynecology examination is a device used to detect the patient's vagina. The common way of use is to expand the patient's vagina with a vaginal dilator, and then insert the detector from the inner cavity of the vaginal dilator. The detection image sampling end is detected in the vaginal cavity, so as to help doctors better understand the condition of the patient's vagina. [0003] There are defects in the existing vaginal voyeuristic instruments when in use. Firstly, the whole vagina of the patient is supported by the vaginal dilator, and the duckbill of the vaginal dilator is attached to the inner wall of the vagina, so that it is very accurate when detecting the inner wall of the vagina. Inconvenient, if th...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the vaginal wall is not easy to detect and the vaginal cavity detection process requires the doctor to swing the detection rod in a large range when the existing vaginal voyeurometer is in use, which will cause the patient's pain to deepen
