Abstract

The invention relates to a pneumatic endoscope anastomat. The pneumatic endoscope anastomat comprises an executing head, an air cylinder, a manual control valve and a control wrench, wherein the executing head is used for cutting and suturing soft tissue; the driving end of the air cylinder is connected to the executing head; the manual control valve is connected to the air cylinder and is used for switching the flow direction of air flow communicating with the air cylinder; and the control wrench is arranged corresponding to the manual control valve and is used for controlling the manual control valve. Due to the fact that the executing head, the air cylinder, the manual control valve and the control wrench are arranged, after the air cylinder is connected with an air source, the manual control valve can be triggered through the control wrench, the air source in the air cylinder switches the flow direction, the driving end of the air cylinder is controlled to move forwards or backwards, and air cylinder actions are transmitted to the executing head to provide power for blade cutting and anastomotic nail discharging and suturing. After execution, the air flow direction of the air cylinder can be switched, and the driving end of the air cylinder retreats. The pneumatic endoscope anastomat is simple in structure and easy to control.

Description

technical field [0001] The invention relates to a laparoscopic stapler, in particular to a pneumatic laparoscopic stapler. Background technique [0002] Laparoscopic staplers, such as medical linear cutting staplers, are used for cutting soft tissues and suturing the edges of the opposite sides of the incision in laparoscopic surgery. Its executive head is equipped with a staple cartridge, anvil and blade, and the operation is mostly manual operation. The corresponding button or wrench is pushed by the surgeon's hand to provide power for the blade to move forward and the staple cartridge seat used to push out the staples. [0003] If the auxiliary drive mechanism can be used to provide power for blade cutting and staple ejection, the doctor's labor can be reduced, which is conducive to reducing operation time and improving operation quality. For example, the Chinese patent document "CN101313865A" with the publication number "Pneumatic Surgical Cutting and Fastening Instrume...
