Medical anus expanding device

Abstract

The invention relates to the field of general surgery department medical auxiliary equipment and in particular to a medical anus expanding device. The medical anus expanding device comprises a main body, a guiding cap, a binding ring and a sphincter relaxation mechanism for controlling the main body to be rhythmically expanded and shrunk. The main body can be formed by multiple floating strip plates by which a cylindrical shape is surrounded together. One end of the floating strip plate is hinged to the guiding cap, and the other end is slidably installed on the binding ring. The middle of thefloating strip plate is further provided with an operating window. The sphincter relaxation mechanism comprises a shrinking unit and an expanding unit. The shrinking unit is a shrinking film sleeve sheathed outside the main body and the guiding cap. The expanding unit comprises a support ring and a rotating shaft. The rotating shaft is provided with a first lug boss. The inner sides of the floating strip plates are provided with second lug bosses. The first lug boss can successively and intermittently contact and cooperate with all of the second lug bosses along with continuous rotation of the rotating shaft. The medical anus expanding device is capable of relieving pain in an anus expanding process and reducing injury to an anus sphincter generated by the anus expanding device itself inexamination, treatment or operation processes.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment for general surgery, in particular to a medical anal dilator. Background technique [0002] Anal dilator is a commonly used auxiliary device in general anorectal department. important role in surgery. [0003] The anal dilator in the prior art generally includes a straight cylindrical body and a tapered guide cap arranged at the end of the body. When in use, the main body of the anal expander is slowly inserted into the anus from the guide cap at the front end until the anal canal, and then inspection and treatment instruments are arranged in the inner cavity of the main body, or an operation space is formed by the inner cavity of the main body. This type of anal expander has the following problems: on the one hand, because the diameter of the anal expander body is usually relatively large, even if there is a guiding effect of the guide cap, its body part is still not easy to enter the...

AI Technical Summary

Problems solved by technology

This type of anal expander has the following problems: on the one hand, because the diameter of the anal expander body is usually relatively large, even if there is a guiding effect of the guide cap, its body part is still not easy to enter the anus smoothly, causing severe pain to the patient during the insertion process. Pain

During some anal expansion operations, the medical staff will even use fingers to open the anus first, and then insert the anal expander as a whole, which will cause excessive force on the sphincter muscle instantaneously, resulting in tearing of the sphincter muscle, which is not conducive to postoperative recovery

On the other hand, the anal dilator in the prior art is all close to the inner wall of the anal canal during inspection, treatment or operation, and the fixed support form of the anal dilator in the prior art prevents the anal position sphincter from breathing or breathing with the patient. Contraction and relaxation driven by other muscle groups, long-term rigid fixation can easily lead to chronic damage to the sphincter, leading to postoperative fecal incontinence and prolonging the recovery period of the disease
