Stapler and staples for anastomosis of lesion tissues of different thicknesses

Abstract

The invention discloses a stapler and a staple for anastomosis that can anastomose lesion tissues of different thicknesses, and belongs to the technical field of medical devices. The key points of the technical solution include a stapler body, the bottom of the stapler body is hinged with a firing rod, and the The left side of the stapler body is fixedly connected with a firing tube, the inner wall of the firing tube is movably installed with a stapling chamber, the inner wall of the firing tube is slidably connected with a pressure ring, and the inner wall of the anastomotic chamber is slidably connected with a positioning rod. The positioning rod runs through the anastomosis chamber and is fixedly connected with an anvil. The present invention provides anastomotic nails. The medical staff can choose two different specifications of anastomotic nails according to the thickness of the lesion tissue resected by the patient, increasing the scope of application of the anastomotic nails. And the nail anvil with high outer circle and low inner circle composed of outer warehouse seat and inner warehouse seat can achieve good hemostasis and good blood supply. The double-circle anastomotic warehouse seat can be used to anastomose the patient's lesion wound. More uniform, more efficient anastomosis, less bleeding.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more particularly, to a stapler and staples for anastomosis that can perform anastomosis on lesion tissues of different thicknesses. Background technique [0002] With the development of medical science and technology, doctors have changed from the original manual suture with needles and threads to the suture with medical staplers and alloy staples. The use of medical staplers for suture, easy operation, safe anastomosis and little trauma has been accepted by the majority of surgical clinicians. [0003] In practice, it is found that the staple tip of the staple has a great influence on the working performance of the staple. Due to the improper design of staple shape and staple tip, it is easy to fall off the anastomosis and uneven anastomosis after anastomosis, which has poor hemostatic effect during anastomosis and affects the healing effect, and the staple cartridge cannot be repl...

AI Technical Summary

Problems solved by technology

Due to the improper design of the staple shape and nail tip, it is easy to fall off from the anastomosis after anastomosis and the anastomosis is uneven. The hemostatic effect during anastomosis is poor, which affects the healing effect, and the staple cartridge part cannot be replaced according to the patient's disease. Therefore, a stapler and an anastomotic staple that can anastomose lesion tissues of different thicknesses are provided to solve the problems raised in the above-mentioned background technology
