Abstract

The invention provides a high segment arc stapling instrument comprising two handle clamp seats mutually hinged to form a scissor shape. The tails of the handle clamp seats are holding parts, the front end of the handle clamp seat is provided with a clamping chuck component, the clamping chuck component comprises clamp seats arranged at the front ends of the handle clamp seats, each of the clamp seats is internally provided with a stapler capable of relatively sliding, a staple-pushing piece and a staple are arranged in the stapler, each stapler is arranged into a semicircle ring, a staple anvil is connected into the ring and is formed by detachably connecting two semi-rings, when the whole staple anvil is combined, the staple anvil comprises a through hole, and tissues can pass through the through hole and covers the top surface of the staple anvil. The invention has the advantage of satisfying a smaller operation space in use, such as operations of high segment of esophagus and low segment of rectum, thereby widening the application range of appliances and providing convenience for doctors.

Description

technical field [0001] The invention relates to a binding instrument used in surgical operations, in particular to an arc-shaped binding instrument suitable for high esophageal and low rectal operations, and belongs to the technical field of medical instruments. Background technique [0002] Surgical circular tube binding instrument is a medical device often used in surgical operations on intestinal and other physiological tissues. The difference in the performance of the instrument plays a vital role in the overall surgical effect. This type of binding instrument mostly adopts the axial inner binding method, and the two sections of tissue are restrained during binding, and a binding ring is formed inside the tissue. U.S. Patent No. 5,205,459 discloses a circular tube type binding instrument with the above-mentioned structure. The advantage of this instrument is that the body hemorrhage generated during the operation can be discharged together with the contents, and the body...
