Fixed angle type needle holder

Abstract

The present invention provides an angle fixing type needle holder for surgical operation, relating to medical instruments field, the needle holder comprises a needle holding body at front end and a hand-held operating handle (8) at rear end, the needle holding body comprises a couple of chucks (1) and (2) moving coaxially along a straight line, occlusal surfaces matching each other are provided between the chuck (1) and (2); an slope angle is formed between the occlusal surfaces and the principal axis of the needle holder; the chuck (2) is fixed on bottom of a hollow external tube (3), the chuck (1) is fixed on bottom of a pull rod (4) sleeved into the external tube (3) and movably connected to the external tube (3). According to the invention, the angle fixing type needle holder may alter holding angle of the needle in certain range such that the needle is hard to slidably drop or rotate in condition of small notch on body surface; and the needle holder may reliably suturing at deep position without damnifying tissue around.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a fixed-angle needle holder for surgical operations. Background technique [0002] The needle holder is an indispensable instrument for suturing wounds in surgical operations. The main shape of the needle holders currently used clinically is a scissor structure, that is, two clamping units are hinged and connected in the form of scissors, such as the shape of a needle-nose tool pliers. Only smaller and longer. The needle clamping of this scissor-type needle holder is realized through the left and right opening and closing of the scissor-type needle holder. The insertion and extraction of the sewing needle are carried out alternately during the suture process, and the opening and closing of the needle holder also travels along the suture edge. On the one hand, it is easy to accidentally injure the surrounding soft tissues. It is necessary to reserve a larger surgical incision...

AI Technical Summary

Problems solved by technology

In this way, if the suture needle is perpendicular to the suture edge when suturing the suture edge parallel to the main axis of the needle holder, the suture operation will be more convenient; and if the suture edge is perpendicular to the long axis of the needle holder, the suture needle and If the suturing edges are parallel, the suturing operation will be very difficult; generally doctors have to constantly change the position of the handle to adjust the direction and angle of the needle holder; The movable space of the handle of the device is often limited, and in many cases it can only be continued by obliquely clamping the sewing needle; but the angle of the oblique clamp should not be too large, on the one hand because of the difficulty in operation, on the other hand, the seam after obliquely clamping The needle is easy to change the angle. At present, there is no needle holder that is convenient for oblique needles.
