Anastomat capable of anastomosing focus tissues with different thicknesses and anastomosis nails

Abstract

The invention discloses an anastomat capable of anastomosing focus tissues with different thicknesses and anastomosis nails, and belongs to the technical field of medical instruments. The anastomat is characterized by comprising an anastomat body, wherein a percussion rod is hinged to the bottom of the anastomat body, a percussion tube is fixedly connected to the left side of the anastomat body, an anastomosis bin is movably installed on the inner wall of the percussion tube, a pressing ring is slidably connected to the inner wall of the percussion tube, a positioning rod is slidably connected to the inner wall of the anastomosis bin, and the positioning rod penetrates through the anastomosis bin and is fixedly connected with a nail anvil. According to the anastomat, the anastomosis nails are arranged, medical staff can select two different specifications of anastomosis nails according to the thickness of the focus tissues needing to be cut off by a patient, and the application range of the anastomosis nails is enlarged; the nail anvil composed of an outer bin base and an inner bin base and provided with a high outer ring and a low inner ring can achieve the effects of good hemostasis and good blood supply; and the double-ring type anastomosis bin base is adopted, anastomosis can be more uniform at the focus wound of the patient, the anastomosis efficiency is higher, and bleeding is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, to a stapler and a staple for anastomosis that can anastomose lesion tissues of different thicknesses. Background technique [0002] With the development of medical science and technology, doctors have changed the way of suturing human tissues or organs from the original manual suturing with needles and threads to the way of suturing with medical staplers and alloy staples. The use of medical staplers for suturing is easy to operate, safe and causes little trauma, and has been accepted by the majority of surgical clinicians. [0003] It has been found in practice that the nail tip of the staple has a great influence on the working performance of the staple. Due to the improper design of the shape of the staple and the nail tip, it is easy to fall off from the anastomosis after the anastomosis and the anastomosis is uneven, and the hemostatic effect during the a...

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
