Automatic microscopic suturing instrument for self-retaining laryngoscope

Abstract

The invention discloses an automatic microscopic suturing instrument for a self-retaining laryngoscope, and particularly relates to the technical field of medical instruments, the automatic microscopic suturing instrument comprises a first lantern ring support plate, a second lantern ring support plate is mounted below the first lantern ring support plate, and a superposition linkage mechanism is embedded in one side of the first lantern ring support plate; the stacking linkage mechanism comprises a first transmission screw which is arranged on one side of the first lantern ring support plate and installed in an embedded mode, the outer wall of the first transmission screw is connected with a first transmission ring block, and a downward-moving driving motor is installed at the top end of the first transmission ring block. A superposition linkage mechanism is adopted, the second lantern ring support plate moves rightwards, the left side mucous membrane layer and the right side mucous membrane layer are placed in a superposition mode, in this way, superposition suturing can be conveniently achieved during suturing, suturing firmness is better, even if the hand shakes, the two sides are vertically clamped and carried, falling is avoided, and firmness is better.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more particularly, to an automatic microsuturing device for supporting a laryngoscope. Background technique [0002] Support laryngoscope surgery is generally the surgical resection of the mucosal lesions of the laryngeal cavity. After the operation, the residual mucosa may need to be sutured. Usually, the operator needs to hold a small suture needle in one hand with a special needle holder under the support laryngoscope. , pass through the mucosa to be sutured, and then use another supporting laryngoscope clamp with the other hand to catch the small fine needle that passes through the mucosa, and pull the needle and thread out of the tissue, after a certain length of suture , use a clamp in one hand to wrap the needle tape thread into a 360-degree circle, and pull the end of the thread through the circle with the other hand to tie the knot.

AI Technical Summary

Problems solved by technology

[0004] Based on the above-mentioned patents, there are two techniques of manual and automatic stitching when stitching, but stitching requires one needle for stitching, and it is impossible to form dislocation superimposed stitching, so the firmness of stitching is low when stitching. And the suture efficiency is poor, once the hand shakes, it will cause suture misalignment, so the suture effect is poor
