a stapler

Abstract

The invention provides a suture device. The suture device comprises a fixed handle, a trigger handle, a component clamping plate, a staple pushing plate and a slide pin. The trigger handle is capable of rotating relative to the fixed handle, the component clamping plate is connected with the trigger handle, and the slide pin is provided with a slide pin protrusion. Inner walls of two sides of the fixed handle are provided with opposite rail grooves, and bottom walls of the rail grooves are provided with inclined surfaces which are identical in size and inclination angle but opposite in inclination direction. The component clamping plate is provided with a clamping plate protrusion which is provided with a slide groove, the slide pin penetrating through the slide groove is capable of axially moving in the slide groove, and two ends of the slide pin are arranged in the opposite rail grooves respectively. The staple pushing plate is provided with a limiting protrusion, and the limiting protrusion can be matched with the slide pin protrusion to limit movement of the staple pushing plate. The suture device has the advantage that false triggering caused by violent movement during transport is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a stapler. Background technique [0002] In medical and surgical operations, since the first staple products appeared in the 1960s, medical staplers have become an indispensable medical device to assist in the process of knife-edge suturing. With the development of medicine and the research and development of new products, more and more multifunctional staple products are used in clinical practice. The scope of application has been involved in various fields such as gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, obstetrics and gynecology, and has become one of the indispensable tools for doctors. The use of staplers and staples for suturing has many advantages such as less intraoperative bleeding, shorter operation time, using instruments instead of manual operations to reduce errors caused by manual operations, avoiding infection, and fa...

Problems solved by technology

[0004] When this stapler product is in the process of transportation or storage, the initial state of the instrument is the unfired state, and the staple cartridge is fixed, but when the instrument is subjected to severe external force impact, the pusher plate may move to the distal end due to inertia, thus Push out the staples in the staple cartridge, causing accidental firing, and then push the nail plate to bend the staples, causing the instrument to not work normally
