Abstract
The utility model relates to a pouch forming pliers for realizing staggered clamping, which comprises a left piece, a right piece, a left clamping head and a right clamping head, wherein the left clamping head is fixed at the end part of the left piece, the right clamping head is fixed at the end part of the right piece, the left clamping head and the right clamping head are respectively provided with wavy clamp teeth which are arranged in a staggered mode along the direction vertical to a clamping surface, and the wavy clamp teeth of the left clamping head are meshed with the wavy clamp teeth of the right clamping head. When the pouch forming forceps for realizing staggered clamping is adopted, when a cut or a tissue stub is clamped, the tissue can be extruded into gaps between the teeth by utilizing the wavy teeth which are staggered on the clamping end surfaces, folds which are more suitable for suturing are formed, empty needles and missed needles are avoided when the pouch is sutured, and the pouch suturing quality can be obviously improved.
Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to the field of surgical medical instruments, and specifically relates to a purse-string forceps for realizing staggered clamping.
Background
The purse-string suture method is a common surgical suture method, is simple to operate, and the sutured wound is also beneficial to healing. Purse string sutures are often used for closure of small incisions or pin eyes in the gastrointestinal tract, for embedding of appendiceal stumps, and for suturing fistulae tubes for fixation of organs. In a surgical operation, when performing purse string suture, a clinician sometimes uses a purse string forming forceps to clamp a tissue, so as to help the purse string forming and reduce the difficulty of the purse string suture.
When the pouch forming forceps are used for assisting pouch stitching, the pouch forming forceps are generally used for clamping an incision or a tissue stub, a fold is formed by utilizing a gap between clamping end faces of the pouch forming forceps, a pouch stitching needle penetrates through the fold through a through hole at the clamping end of the pouch forming forceps, and a pouch is formed after the pouch forming forceps are loosened. The gaps of the clamping end surfaces of the traditional purse string forming forceps are symmetrical gaps, natural folds are formed by tissue elasticity during clamping, empty needles and missed needles are easy to form during purse string suturing, and the purse string suturing quality is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide the purse forming forceps which have the advantages of simple structure, convenience in operation and wider application range and can realize staggered clamping.
In order to achieve the above object, the purse-string forming forceps for realizing staggered clamping of the utility model is as follows:
the lotus bag forming pliers capable of achieving staggered clamping is mainly characterized by comprising a left piece, a right piece, a left clamping head and a right clamping head, wherein the left clamping head is fixed at the end of the left piece, the right clamping head is fixed at the end of the right piece, the left clamping head and the right clamping head are respectively provided with wavy clamp teeth which are distributed in a staggered mode in the direction perpendicular to a clamping surface, and the wavy clamp teeth of the left clamping head are meshed with the wavy clamp teeth of the right clamping head.
Preferably, the left clamping head and the right clamping head are respectively provided with a left suture groove and a right suture groove along a direction perpendicular to the wavy teeth, and the left suture groove and the right suture groove are meshed to form a circular through hole in a closed state of the left clamping head and the right clamping head.
Preferably, the left clamping head and the left piece form a bending angle, and the right clamping head and the right piece form a bending angle.
Preferably, the left piece and the right piece are connected through a hinge, and a hinge shaft is arranged at the joint of the left piece and the right piece.
Preferably, the hinge shaft is a cylindrical pin.
When the pouch forming forceps for realizing staggered clamping is adopted, when a cut or a tissue stub is clamped, the tissue can be extruded into gaps between the teeth by utilizing the wavy teeth which are staggered on the clamping end surfaces, folds which are more suitable for suturing are formed, empty needles and missed needles are avoided when the pouch is sutured, and the pouch suturing quality can be obviously improved.
