Problems solved by technology

[0003]In order to realize machine operation and replace manual operation, some special appliances or instruments have begun to appear in the prior art to assist doctors to complete this process, but the existing The structure of this device is usually relatively simple, and the functions it realizes are also relatively single, especially the combined structure of expanding diameter and rotating massage cannot be realized, and if the dual functions of expanding diameter and rotating massage can be realized, this process will become easier and simple, and achieve better results

Abstract

The invention provides an instrument for anorectal surgery operation and a using method of the instrument. The anorectal surgery operation is a very important medical treatment branch, an anus part often needs to be expanded in the process of treating anal fissure diseases in the anorectal surgery operation, and the most traditional mode lies in that a doctor completes the process through fingers. The instrument structurally comprises an extending body, a supporting and connecting structure, a diameter expanding structure and a rotary driving assembly. Through the arrangement of the diameter expanding structure, the diameter expanding effect on the anus part can be achieved through the expanding effect of a sheet body structure, and besides, through the driving effect of a rotating motor, the whole diameter expanding structure, especially the sheet body structure, forms the slow rotating effect, so that the better diameter expanding effect is achieved. In addition, through the arrangement of inclined bent driving grooves, the driving effect on a driving head and sliding plates is achieved in the rotating process.

Description

technical field [0001] The invention relates to an instrument structure for medical operation, in particular to an instrument for anorectal surgery and its use method. Background technique [0002] Anorectal surgery is a very important branch of medical treatment. In the process of treating anal fissures in anorectal surgery, it is often necessary to expand the anus, and the most traditional way is for doctors to complete this process with their fingers. And it is necessary to add some lubricating fluid and massage properly, and then gradually complete the expansion of the anal area. [0003] In order to replace manual operation with machined operation, some special appliances or instruments have appeared in the prior art to assist doctors to complete this process. However, the existing devices are usually relatively simple in structure, and their functions are relatively single. In particular, the combined structure of diameter expansion and rotary massage cannot be realiz...
