Abstract

The invention discloses a continuous deep tissue sutural unit, belonging to surgical medical instrument, which is characterized in comprising a casing, a driving device and a lock thread device; wherein, the casing comprises a lower and an upper parts through locking; the driving device comprises an inner rod, a rack and a central axis; the lock thread device comprises a thread jamming device, a high slide way and a low slide way; the high slide way and the low slide way are arranged in parallel at the front part of the casing and are combined together at the tail end of suture needle. The continuous deep tissue sutural unit can be widely applied in operation suturing upon patients such as surgery and otorhinolaryngology in large-size, middle-size and small-size hospitals and clinics. The continuous deep tissue sutural unit can be used in an endoscope if the sutural unit is made small enough. The continuous deep tissue sutural unit has the advantages of continuous operation, stable operation, convenience and swiftness, safe and easy replacement of vulnerable parts and simple production process.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a surgical medical instrument—a continuous deep tissue stapler. Background technique [0002] The utility model patent "deep tissue suturing device" with the application number of 2005200918221 discloses a device for surgical suturing, which includes an inner rod, an outer cylinder, and a suture needle. Tissue, pull the outer cylinder, the suture needle moves through the tissue, the thread clamp hooks the suture, pulls out the stapler to form the state that the suture passes through the tissue, and completes one operation. Although this stapler is simple and easy to operate, it can only sew one stitch at a time, cannot be operated continuously, and its stability is not strong, requiring complicated production technology, and it cannot be made into a very small model. Contents of the invention [0003] The object of the present invention is to propose a ...
