Anal dilator for pediatric general surgery department

Abstract

The present invention discloses an anal dilator for the pediatric general surgery department. The anal dilator comprises a shell, a dilation block, a guide head, a tail handle and an air guide pipe, three strip-shaped grooves are evenly distributed in the circumferential surface of the shell, the guide head is installed at one end of the outer portion of the shell, a supporting column is arranged on the inner side of the shell, a second air bag is installed on the outer side of the supporting column, three expansion blocks are arranged on the outer side of the second air bag and in the three strip-shaped grooves, the tail handle is installed at the other end of the shell, the air inlet of the second air bag is connected with the air guide pipe, and an on-off valve is installed at the other end of the air guide pipe. The anal dilator is simple in structure and convenient to use, can relieve the physiological pain of a child patient, enables the three expansion blocks to be in different expansion states by changing the amount of gas filled in the second air bag, is simple, practical and easy to operate, reduces the labor intensity of medical staff, and has high application and popularization value.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anal dilator for general surgery of children. Background technique [0002] At present, it is known that in the course of clinical medical treatment, anal reconstruction surgery is performed on infants with congenital anus. After the reconstruction anus surgery, anal dilators of different diameters need to be used every day to expand the contraction ability of the anus. The dilator is composed of a group of round rods with different diameters. When using it, use the smaller diameter round rod first, insert it into the reconstructed anus, pull it out after a period of time, and then insert a thicker round rod, and so on until the The round rod with the thickest diameter is drawn out as a course of treatment. This technology will cause great pain to the child when inserting and pulling out the round rod, and the operation requires experienced medical staff to operate...
