multifunctional hernia needle

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and particularly relates to a multifunctional hernia needle. The multifunctional hernia needle comprises an outer needle, an inner core and a valve, and the outer needle and the inner core are each of a hollow structure; the hernia needle further comprises an inner core spring front fixing screw, a spring, a sleeve and a double-groove spring fixing screw; the tail end of the outer needle is provided with a spring cavity, the inner core is arranged in the outer needle, the front end of the inner core is provided with a blunt body with an arc-shaped protection face, the side face, close to the blunt body end, of the inner core is provided with a round empty concave groove, and a spring outer baffle is fixed at the tail end of the inner core; the double-groove spring fixing screw is connected to the tail end of the outer needle in a threaded mode, the inner wall of the double-groove spring fixing screw is correspondingly provided with a groove in the length direction, and the groove is matched with a tooth-shaped locating block arranged on the rear middle portion of the inner core; the spring is installed between the inner core spring front fixing screw and the double-groove spring fixing screw. Components are easy to disassemble and assemble and convenient to disinfect, and assembling modes needed by different functions are met.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a multifunctional hernia needle. Background technique [0002] Veress needle is a surgical instrument used in laparoscopic surgery to judge whether the needle insertion position is correct and to inflate carbon dioxide gas to form pneumoperitoneum. Laparoscopic surgery is performed using laparoscope and related instruments. It is a newly developed minimally invasive method. Compared with traditional surgery, laparoscopic surgery has the characteristics of less trauma, faster recovery, and smaller scars. Minimally invasive surgery It is the general trend and pursuit goal of surgical development. Generally speaking, most general surgery operations can be performed laparoscopically. At present, laparoscopic surgery is also used in the treatment of inguinal hernia in children. When performing laparoscopic inguinal hernia hernia sac high ligation in children, it is neces...

AI Technical Summary

Problems solved by technology

It can be used not only as a Veress needle, but also as a Hernia needle, but its disadvantages are as follows: 1. The material used is plastic, which is a disposable product, which increases the medical cost; 2. The structure is fixed, especially the position of the spring is fixed, so it cannot Make full use of the mechanical characteristics of the spring; 3. When used as a hernia needle, the purpose of hiding the hook-shaped gap is achieved by rotating the outer needle joint, instead of using the elasticity of the spring to expand the inner core to expose the hook-shaped gap of the inner core. The thread rotation stability is slightly poor, and the thread may be cut during the rotation process, affecting the texture of the thread
