Anastomat capable of discharging nails at constant speed

Abstract

The invention relates to the technical field of anastomats, and discloses an anastomat capable of discharging nails at a constant speed. The anastomat comprises a fixed handle, a nail pushing assembly and a nail seat assembly, a fixed shaft is fixedly installed between the two side walls of the fixed handle, limiting nuts are arranged at the two ends of the fixed shaft, guide grooves and clamping grooves are formed in the surfaces of the inner walls of the two sides of the front end of the fixed handle, and first rectangular installation holes are formed in the surfaces of the guide grooves; the nail pressing assembly is movably installed in the fixed handle, a nail bin assembly is fixedly installed at the bottom of the front end of the fixed handle, the nail seat assembly is arranged on the inner surface of the nail bin assembly, the nail pushing assembly is movably connected with the nail seat assembly, the nail seat assembly comprises a nail seat, an installation plate is arranged at the bottom of the nail seat, and anastomosis nail containing grooves are formed in the two sides of the exterior of the nail seat. A servo motor is arranged at the tail end of the nail seat to push the anastomosis nails to move, the purpose of discharging the nails at a constant speed is achieved, the process of manually triggering the anastomosis nails is better matched, and the wound suturing effect is improved.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a uniform-speed stapler. Background technique [0002] Stapler is a device used in medicine to replace manual suture. The main working principle is to use titanium nails to separate or anastomose tissues. Compared with traditional manual suture, instrument suture is simple and convenient, saves operation time, and can be used once. Effectively avoid cross infection. Due to the development of modern science and technology and the improvement of production technology, the clinically used staplers are reliable in quality, easy to use, tight and suitable for tightness, especially their fast suturing, easy operation and few side effects and surgical complications. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, bloo...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a uniform-speed stapler, which has the advantages of uniform-speed nail output, precise nail pressing, and quick reset, and solves the problem of uneven nail output speed and nail plate pressing of existing skin staplers. The problem of the direction of time shifting and the reset effect of the active handle is not good
