Anal dilatation instrument for gastrointestinal surgery

Abstract

The anus dilatation instrument comprises a mounting box, an anus medicine injection assembly is mounted on the outer wall of the top of the mounting box, a linkage anus dilatation assembly is arranged on the outer wall of the bottom of the mounting box, a video observation assembly is arranged on the outer wall of one side of the mounting box, and the anus medicine injection assembly comprises a syringe mounted at the top of the mounting box in an embedded mode; side handles are symmetrically fixed to the outer walls of the two sides of the top end of the syringe, a guide column is fixed to the center of the inner wall of the bottom of the syringe, a piston sleeves the outer wall of the guide column, and a pull pipe is connected to the outer wall of the top of the piston and sleeves the guide column; through the arrangement of the linkage anal dilatation assembly, a user presses a pressing block again to drive a movable column to move in a guide hole, the movable column drives a double-face rack to move, dilatation plates on the two sides of the end are driven to be oppositely unfolded under matched transmission of the double-face rack and a half gear, and therefore anal dilatation half cylinders on the two sides are driven to be unfolded, and anal dilatation operation is achieved; and the operation is relatively simple.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anal expansion instrument for gastrointestinal surgery. Background technique [0002] In the work of gastrointestinal surgery, it is necessary to frequently check the patient's anorectal outlet. During the treatment and inspection process, anal expansion is often required. Anal expansion is also called anal canal expansion. It is a method of expanding the anus with fingers or instruments; anal expansion is often used for anorectal diseases. Examination, treatment and postoperative recovery; anal expansion instrument is often used in the process of anal expansion; [0003] The existing anal expansion instruments on the market are relatively simple in structure, and need to be operated by medical personnel during use. The operation is inconvenient, and the size of the anal expansion cannot be adjusted step by step, and the anus cannot be visually observed in real time ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the inability of the anal expansion instrument in the prior art to adjust the size of the anus step by step. During the operation of the anal expansion, it is impossible to visually observe the anus in real time, which is not convenient for the user to operate independently, and does not have the ability to apply medicine. In order to solve the above-mentioned technical problems
