Anal dilatation device for department of pediatrics

Abstract

An anal dilatation device for the department of pediatrics comprises a handle, a center rod, a sliding sleeve assembly and an arc-shaped dilatation plate. The center rod is fixedly arranged at the front end of the handle. The sliding sleeve assembly is arranged on the center rod in a sliding mode. A plurality of arc-shaped expansion plates are rotatably arranged around the center rod, front connecting rods and rear connecting rods are rotatably arranged on the arc-shaped expansion plates, the inner ends of the front connecting rods are rotatably arranged on the center rod, and the inner ends of the rear connecting rods are rotatably arranged at the front end of the sliding sleeve assembly. A guide seat is fixedly arranged on the center rod, and the rear end of the arc-shaped expansion plate is arranged in the guide seat in a sliding mode. A trigger is rotatably arranged on the handle, and the upper end of the trigger is rotatably arranged on the sliding sleeve assembly. The anal dilatation device has the advantages that the diameter can be adjusted step by step without pulling out the anus dilatation device, anus dilatation is achieved step by step, manpower and material resources are saved, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pediatric anal expansion device. Background technique [0002] In pediatrics, infants and young children who are congenitally without anus need to undergo surgery to reconstruct the anus. The newly created anus needs to be expanded with different anus expanders every day to exercise the contraction ability of the anus. When expanding the anus, the child suffers a lot and the sphincter is not enough Relaxation, the anal expansion action should be gentle, and the anus should not be opened violently and quickly, otherwise it will easily cause multiple tears of the mucous membrane and anal canal, and symptoms of anal canal tearing will also occur. The currently used anal dilator is composed of a group of metal round rods with different diameters. The disadvantage of this anal dilator is that the round rods need to be replaced many times. Caused greater pain and...

The currently used anal dilator is composed of a group of metal round rods with different diameters. The disadvantage of this anal dilator is that the round rods need to be replaced many times. caused more pain and harm to patients

There are also inflatable anal expanders, but the effect of the inflatable anal expander is not ideal. When the anus is forced to contract, it is easy to squeeze and deform the inflatable anal expander, and the effect of anal expansion cannot be achieved.
