A needle holder for automatic suturing

Abstract

The invention discloses a needle forceps for automatic stitching, which comprises a binding clip fixed shaft, an upper binding clip, a lower binding clip, a push rod assembly and a suture needle. The upper binding clip and the lower binding clip are mutually superimposed to be connected with the binding clip fixed shaft via a binding pin. The push rod assembly is arranged in an X-direction hollow space of the binding clip fixed shaft. The suture needle is arranged in a Z-direction needle hole of the upper binding clip and the lower binding clip in the Z-direction. Through controlling a handle and adjusting the fore-and-aft movement distance of an upper ejector rod, a push rod and a lower ejector rod along the X-direction, the upper binding clip and the lower binding clip are opened and closed in the form of the reciprocating movement. In this way, the stitching purpose of feeding a needle, withdrawing the needle and leading a wire is realized under the manual control effect of the linear suture needle. The needle forceps has the features of simple structure, convenient disassembly and flexible operation. By means of the needle forceps, operating steps are greatly simplified and the operation difficulty is lowered. Therefore, the needle forceps has an important significance on the suture of wounds.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a needle-holding forceps which can automatically change needles and is used for automatic suturing. Background technique [0002] Needle-holding pliers are used in the operation, which is a commonly used medical instrument for clamping medical sutures and suturing wounds of patients. The medical needle-holding forceps in the prior art need Relatively large operating space and high requirements for the operator's technical proficiency make suturing difficult, and the medical needle holders of the prior art are only suitable for suturing wounds on the human body surface, and the suture needs to be located in the human body. For deep wounds, it is necessary to make a large enough incision on the human body surface and free the tissues in the body to provide the space required for suturing with needle-holding forceps. The operation is difficult, takes a long time, and causes great...
