Abstract

A circular stapler comprising a stapler main body (10), an anvil component (20) matching the stapler main body (10), an operating handle (30) pivotally connected to the stapler main body (10), and a staple pushrod (115) arranged within the stapler main body (10). The staple pushrod (115) is provided with an initial position and a firing position. The operating handle (30) is capable of driving the staple pushrod (115) to move from the initial position of the staple pushrod (115) to the firing position of the staple pushrod (115). The circular stapler also comprises a brake pin (113) pivotally connected to the stapler main body (10). The brake pin (113) is provided with an initial position and a secondary firing prevention position. When the brake pin (113) is at the initial position thereof, the operating handle (30) and the brake pin (113) are provided therebetween with a gap. When the brake pin (113) is at the secondary firing prevention position thereof, the operating handle (30) is in contact with the brake pin (113). The present circular stapler allows for effective prevention of secondary firings, thus preventing medical accidents from occurring.

Description

technical field [0001] The invention relates to a circular tube stapler, which belongs to the technical field of medical instruments. Background technique [0002] The round tube stapler is a medical device often used in surgical operations on physiological tissues such as the digestive tract. Most of this type of stapler adopts the axial inward binding method. During the anastomosis, the two sections of tissue are restrained and a circular anastomotic ring is formed inside the tissue. Tissues heal relatively easily. [0003] Currently, a circular-tube stapler for treating hemorrhoids includes a stapler body, an operating handle movably connected to the stapler body, and an anvil assembly matched with the body. The stapler body includes an annular staple cartridge and a cutting knife arranged at the distal end. The anvil assembly includes a conical anvil, an anvil cap fixed on the top of the anvil, a knife anvil arranged inside the anvil, and an anvil shaft detachably con...
