Auxiliary instrument for hemorrhoid cutting surgical operation

Abstract

The invention discloses an auxiliary instrument for a hemorrhoid cutting surgical operation. The auxiliary instrument comprises an anal dilatation cylinder main body; an elastic sleeve is fixedly connected to the outer side of the anal dilatation cylinder main body; one end of the anal dilatation cylinder main body is fixedly connected with an annular elastic bag; and the end, away from the anal dilatation cylinder main body, of the annular elastic bag is fixedly connected with an dilatation cylinder; a guide rod movably penetrates through the dilatation cylinder; a plurality of lubricating liquid passages are formed on the side wall of the anal dilatation cylinder main body in the axial direction; the dilatation cylinder is fixedly connected with an insertion rod movably inserted into an extending groove; and the end, extending into the extending groove, of the insertion rod is fixedly connected with a first power-on block. According to the invention, during use, through the arrangement of the elastic sleeve, a lubricating liquid baffle and other structures, lubricating liquid can only flow out of the lubricating liquid passage entering the anus so as to avoid the situation that the lubricating liquid flows out of an anus dilatation cylinder outside a human body and drips on an operating table; and through the arrangement of an electric heating rod, a branch power-on plate and other structures, the lubricating liquid is heated so as to reduce discomfort of a patient and the operation difficulty.

Description

technical field [0001] The invention relates to the field of anorectal medical technology, in particular to an auxiliary instrument for cutting hemorrhoid surgery. Background technique [0002] With the increase of life pressure and the optimization of office technology, people sit for a long time, and hemorrhoids have gradually become a common and frequently-occurring disease. Before hemorrhoid surgery, it is necessary to lubricate the anus to ensure that surgical instruments can enter the anus smoothly and reduce Surgical instruments cause unnecessary damage to the anus. [0003] In the prior art, the application number is "202010464490.6", a lubricating device for anorectal surgery, which includes a base and anal expansion cylinder, a deceleration mechanism is connected to one end of the anal expansion cylinder, and a syringe filled with lubricating fluid is connected to the base , the input end of the syringe is connected to the deceleration mechanism, the anus expansio...

AI Technical Summary

Problems solved by technology

[0004] But the prior art still has many deficiencies, such as: 1. In order to achieve a good lubricating effect, it is necessary to provide multiple liquid outlets on the anus expansion tube, and the multiple liquid outlets discharge liquid simultaneously during the anal expansion tube advancement process, As a result, the liquid outlet on the anal expansion tube that does not enter the anus also flows out of the lubricating fluid and drips on the operating table, causing pollution to the operating table and causing unnecessary waste; 2. When the anal expansion tube enters the anus, The cold lubricating fluid flowing into the anus will cause discomfort to the human body, causing the contraction of the external sphincter and increasing the difficulty of advancing the anal dilator
