A kind of skin stapler with staple cartridge in front

Abstract

The invention discloses a skin stitching instrument with a front-arranged nail bin plate. The skin stitching instrument comprises an outer handle, an inner handle, a nail pushing piece, a reset spring, the nail bin plate, a nail storage box and a nail conveying mechanism. The outer handle and the inner handle are rotationally connected. The nail bin plate comprises a connection limiting piece, a sliding nail connecting piece, a skin suction part, a nail blocking part and a nail outlet, wherein the connection limiting piece and the sliding nail connecting piece are integrally arranged. The skin suction part comprises an arc groove and wing plates symmetrically arranged on the two sides of the arc groove, and the arc groove is used for sucking the skin to be stitched. By means of the structure, on one hand, the lever principle of human mechanics is utilized, stitching nails can perpendicularly enter the skin with the nail outlet as a fulcrum, and the stitching effect is better; on the other hand, the nail bin plate is arranged on the front part, and the connection limiting piece and the sliding nail connecting piece are integrally arranged so that processing or installation errors can be effectively eliminated, the forming quality of the stitching nails can be high, and the two nail pins of each stitching nail can be exactly perpendicular to the surface of the skin; besides, the stitching instrument is low in manufacturing cost, high in attaching degree with the skin and good in stitching quality.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a skin stapler with a staple cartridge in front. Background technique [0002] After many years of clinical application in general surgery, orthopedics, obstetrics and gynecology, burns, emergency, cardiothoracic surgery, neurosurgery and other surgical departments, the skin stapler has been proved to be effective in suturing the epidermis or grafting skin islands in 10-30cm long wounds. The advantages of quickness and simplicity; it is a major reform of suture technology, it is a good assistant for surgeons, and it is a medical product worthy of popularization and application. [0003] The skin stapler used clinically in the hospital needs to suture the skin firmly without detaching the staples, and the staples are well formed. According to current market understanding and feedback from hospital clinicians, a general skin stapler needs to be used by two doctors, specifi...

AI Technical Summary

Problems solved by technology

[0006] 1. The front-end limit plate of the staples or the staple cartridge plate are processed separately. Due to processing errors and other reasons, the two sides of the front-end limit plate of the staples or the staple cartridge plate may have their own processing errors. When used, it will lead to poor quality of staple formation, and the two claws of the staple may not be completely perpendicular to the skin surface

[0007] 2. The processing error of the front-end limit plate of the staple or the two sides of the staple cartridge plate immediately meets the set requirements. Due to installation reasons, when the front-end limit plate of the staple is installed and fixedly connected with the staple storage box or the outer handle, as well as the staple cartridge plate and the outer handle are installed and fixed. The installation and fixed connection of the staple storage box may also cause installation gaps or errors. Such gaps or errors may also lead to poor quality of the staples, and the two claws of the staples may not be completely perpendicular to the skin surface.

[0008] 3. The front-end limit plate or the staple cartridge plate of the staples are all made of metal, on the one hand, the manufacturing cost is high, and on the other hand, the fit to the skin is also much worse
