Surgical scissor type needle holder

Abstract

The invention relates to a surgical scissor type needle holder, comprising two bodies (4) connected by two scissor-shaped hinges (3), wherein the front ends of the bodies (4) are holding parts (1) with antiskid diamond teeth-shaped jaw surfaces (2) for holding a suture needle, the back ends of the bodies (4) are hand-held parts (6), one hand-held part (6) of one of the two bodies (4) is provided with a thumb ring (7), the hand-held part (6) of the other body (4) is provided with a closing ring (8) for the middle finger, ring finger and little finger, and matched teeth (5) are arranged on the inner sides of the two hand-held parts (6). According to the surgical scissor type needle holder, a ring structure of a hand-held part of the traditional needle holder is enlarged into a scissors-shaped ring, the stability and accuracy in suturing tissues by holding a needle holder are compromised in use, and also the needle holder is more comfortable, flexible and labor-saving when opened and closed, thereby facilitating operation and effectively improving the operation efficiency.

Description

technical field [0001] The invention relates to a surgical operation tool, which is a scissors-type needle holder for surgical operations. Background technique [0002] At present, the needle holder used for suturing tissue in clinical practice is a commonly used instrument in surgical operations. The forceps ring is close to the thenar muscle of the right hand. The thumb, middle finger, ring finger and little finger are pressed on the handle of the forceps respectively. The fish muscle and metacarpophalangeal joints are moved and advanced, the toothed buckle on the handle ring of the needle-holding forceps is opened, the toothed buckle is released, and the opening size of the needle-holding forceps is controlled to hold the needle. However, in the actual clinical application of this traditional manipulation method, the thenar muscle and the metacarpophalangeal joint work together when loosening the jaws. Since there is no effective fulcrum, loosening the jaws is very labor...

AI Technical Summary

Problems solved by technology

However, in the actual clinical application of this traditional grasping operation method, the thenar muscles and the metacarpophalangeal joints are used to loosen the jaws. Since there is no effective fulcrum, it is very laborious to loosen the jaws, which is unstable and easy. The sutured tissue at the front end is pulled and shaken, and it is difficult to expand the opening of the needle holder, especially young surgeons are very uncomfortable, and it takes a long time to practice before they can master this method proficiently
