Abstract

The utility model relates to a cavity suture knotter, which is provided with a handle, a support block and a clamp rod, wherein the handle and the support block are hinged, and are hinged with a rocker arm, the rocker arm and a pull rod seat are hinged on a point, the pull rod seat is connected with a pull rod sleeved in the inner portion of the clamp rod, the top end of the pull rod and the top end of the clamp rod are hinged with a moving clamp head, the moving clamp head is of a bended hook shape, and is provided with a needle clamping area and a knotting area, and the top end of the clamp rod is further stretched with a fixed clamping head. The cavity suture knotter has the advantages that when the moving clamping head of the cavity suture knotter is in the biggest opening state, an included angle of the needle clamping area and the clamp rod is 90-105 degrees, thereby being capable of accurately pulling a suture line to knot through the back surface of the needle clamping area to support the suture line and being not easy to loose lines, and not needing auxiliary of other surgical instruments. Simultaneously, the suture line is firmly bitten by the clamping head of the cavity suture knotter, a needle is not easy to roll, and a coil arranged on the tail portion of a suture line which is made in advance is hooked by the knotting area, thereby leading knotting to be convenient and rapid, being not easy to loose knots, and being excellent in suture effect.

Description

A kind of intracavity stitching knotter

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically, is a kind of intracavity stitching knotter.

Background technology

In human abdominal cavity videoendoscopic surgery process, need sew up operative incision, need stitching thread be tied a knot in the stitching.Present sewing method clinically is to clamp sewing needle by the binding clip of needle holder to sew up, and relends multiple operating theater instruments such as helping needle holder, holding forceps during knotting and cooperatively interacts, and makes a call to earlier a stauros, makes a call to a slip-knot ending with method.There is following drawback in this kind method: it is not firm that (1) needle forceps occurs holding pin easily, and as easy as rolling off a log needle roller, the sewing needle of causing comes off; When (2) utilizing the knotting of needle holder traction stitching thread, stitching thread is easy to come off or untwisting occurs; (3) operating theater instruments that needs is many, and complicated operation causes trouble for the medical operating personnel, and is higher to the specification requirement of operation; (4) operating time is long, influences pneumoperitoneum, can bring misery to patient.

Chinese patent document CN 200820082076.3 on October 22 2008 day for announcing, discloses a kind of folder needle pliering that is used for the intraperitoneal suture operation; This folder needle pliering comprises handle, pull bar, claw beam, fixed pliers head and movable binding clip, also is provided with rocking arm, draw-bar seat, guide pad and rest pad, and an end of rocking arm is fixed on the handle; The other end is fixed on the draw-bar seat; Draw-bar seat is connected with described pull bar, and guide pipe is fixed on the rest pad, and rest pad and described handle are fixed.Though it is better, wear-resistant that this folder needle pliering is held the pin effect, its movable binding clip is the block structure of rectangle, in operative process, still causes sutural coming off when using its back side traction stitching thread knotting easily.Therefore, need badly and a kind ofly can accurately draw stitching thread, guarantee that stitching thread does not come off and then shortens the intracavity stitching knotter of the operating time of tiing a knot.But also do not appear in the newspapers about this type wire twister at present.

Summary of the invention
