Medical stitch taking-out pincers for operation

Abstract

The invention discloses a pair of medical stitch taking-out pincers for an operation. The tail end of an upper pincers head and the tail end of a lower pincers head are connected with the front ends of pincers handles through annular hinges, and pincers grips are arranged at the tail ends of the pincers handles. The back of a blade of the lower pincers head is provided with a suture line stably clamping face, and a reset spring is arranged at the position, close to the hinged position, of the rear end of each pincers handle. The tail portion of each pincers handle is provided with a finger ring used for holding. A clamping protruding block is arranged on the inner side of the end of the upper pincers head. A concave arc is formed in the inner side of the end of the lower pincers head. The clamping block and the concave arc are matched with each other. The outer surface of the upper pincers head and the outer surface of the lower pincers head are provided with seams in a penetrating mode. A cutting knife is hinged to the head portion of the upper pincers head. A blade of the cutting knife is located in the seams. The clamping face enables the lower pincers head to be kept away from the clamping force by a certain distance. The clamping protruding block and the concave arc are matched with each other, and therefore the clamping stability is achieved. When the pair of medical stitch taking-out pincers for the operation is used, a user firstly holds the pincers grips, moves a knife handle of the cutting knife and rotates the blade of the cutting knife in the seams so as to clamp cut off wound stitches, operation is quite convenient, and work efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a medical stitch ripper for operation. Background technique [0002] In the process of medical care, medical staff will use different tools during their operations. In some medical operations that require suture trimming, medical wire cutters are often used. Due to the limited mechanical structure of existing wire cutters, it is easy to affect the patient's wound when cutting the thread, causing secondary injury to the patient, increasing the pain of the patient, and increasing the workload of the medical staff. The size of the gap generated when the jaws of the existing medical stitch rippers are closed produces an unstable state, and because the sutures used in the operation have several specifications in diameter and thickness, the known structures are often limited in use A standard suture, and when the suture with a small diameter is pulled out, the ...

The size of the gap generated when the jaws of the existing medical stitch rippers are closed produces an unstable state, and because the sutures used in the operation have several specifications in diameter and thickness, the known structures are often limited in use A standard suture, and when pulling out a suture with a thinner diameter, it will often cause off-line phenomenon due to the instability of the gap gap when closing
