The invention provides a circular tube type anastomat shell body. The circular tube type anastomat shell body comprises an operating handle which is connected with the circular tube type anastomat shell body in a pivot mode, a nail ejecting rod and a braking pin, and the nail ejecting rod and the braking pin are arranged in the circular tube type anastomat shell body. The nail ejecting rod is provided with an initial position and a percussion position. The operating handle can drive the nail ejecting rod to move from the initial position to the percussion position. An arc-shaped braking pin track groove is formed in the circular tube type anastomat shell body, the braking pin can be movably connected with the braking pin tract groove, and the braking pin tract groove comprises a first extreme position and a second extreme position. When the braking pin is located in the initial position of he braking pin, the braking pin is close to the first extreme position of the braking pin track groove. When the braking pin is located in a twice percussion proof position, the braking pin is close to the second extreme position of the braking pin track groove. Compared with the prior art, the circular tube type anastomat shell body can provide a function of effectively preventing twice percussion and avoids appearance of medical negligence.
Description
technical field [0001] The invention relates to a round tubular stapler casing, 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 detacha...
