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 directi

Embodiment Construction

[0017] In order to further clarify the technical solutions of the present invention, specific implementations will be described in detail below.

[0018] like figure 1 As shown, the fixed-angle needle holder of the present invention is made of medical stainless steel or other medical hard metal materials. Hand-held operating handle 8. The handle 8 is similar to the handle of a traditional scissors-type needle holder. It is a ring handle that can be opened and closed on the left and right, and is very suitable for smart use; an inverted sawtooth bar 9 that can be used as a stop is respectively provided at the intersection of the two handle ends. After the teeth mesh, they can only move in one direction, so that the handle 8 can only be closed inwards and cannot be opened outwards, so as to maintain the force of the needle clamp and prevent the needle from accidentally falling off or dislocation, and it is also beneficial to the operator to make more adjustments.

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...
