Subcutaneous soft tissue stitching instrument and degradable metal stitching nail

Abstract

The invention discloses a subcutaneous soft tissue stitching instrument and a degradable metal stitching nail. The subcutaneous soft tissue stitching instrument comprises a nail pushing mechanism, a nailing mechanism and a nail storage cabin mechanism, the nail pushing mechanism comprises a supporting plate, a top plate, a nail pushing plate reset spring, a pressing block and a nail pushing plate, and the top plate is arranged at the top end of the supporting plate; the top plate is connected with the top face of the pressing block fixing end through a nail pushing plate reset spring, the nail pushing plate is slidably arranged on the supporting plate, and the end face of the pressing block fixing end is fixed to the top end of the side face of the nail pushing plate. The nailing mechanism comprises a nailing track used for containing suturing nails, and the nailing track is arranged at the bottom end of the nail pushing plate. And the nail storage cabin mechanism can continuously push the suturing staples into the nailing track. The effects of continuous nailing and rapid nailing are achieved through the nail pushing mechanism and the nail storage cabin mechanism, the suturing time of muscles or subcutaneous tissues is effectively saved, and surgical trauma and infection risks are effectively reduced; the suturing nail is made of biodegradable magnesium alloy or zinc alloy, can be automatically degraded and absorbed in vivo, and has no adverse side effect.

Description

technical field [0001] The invention relates to the technical field of medical subcutaneous soft tissue suturing instruments, in particular to a subcutaneous soft tissue suturing device and degradable metal staples. Background technique [0002] At present, muscle sutures are still mostly sutured by hand, and the suture speed is relatively slow, which increases the time of operation and anesthesia, and increases the risk of infection during and after surgery. There is an increasing demand for convenient and fast suture instruments and methods in clinical practice. Although some subcutaneous tissue staplers have been used in surgery, most of them are designed for specific purposes (such as luminal anastomosis, etc.), and it is difficult to achieve effective, comfortable and beautiful for damaged and irregular wounds or elastic muscle tissue. , fast suturing effect; and the existing subcutaneous stapler has a huge volume of the nail output part, which blocks or partially block...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention proposes a subcutaneous soft tissue stapler and degradable metal staples to solve the problems caused by the low suturing accuracy and efficiency of the stapler for muscle or intradermal tissue and non-degradable suturing materials. Questions about secondary surgery or late side effects
