Embodiment Construction

[0039] The invention discloses a circular tube binding instrument, which is especially suitable for high esophagus and low rectum operations. Like the prior art, the circular tube binding instrument includes a nail cylinder 2 and an anvil 1 arranged at the front end of the staple instrument, and the nail anvil 1 can move relative to the nail cylinder 2; the nail anvil 1 has a top surface 15, Several nail forming grooves 13 are arranged on it; a nail bin 3 is fixed on the front end of the nail barrel 2, and a nail pushing piece 4 is arranged inside the nail barrel 2, and the nail pushing piece 4 is connected with the nails placed in the nail bin 3. Butt against, and the nail can be pushed out of the nail bin 3 to cooperate with the nail forming groove 13 to form the nail on the tissue 9.

[0040] Such as Figure 1 to Figure 4 As shown, the difference between the present invention and the prior art is that the nail anvil 1 is detachably connected by two half-rings 11, 12. A th...

Abstract

The invention provides a round pipe type stapling apparatus suitable for the high-position esophageal operation. The stapling apparatus comprises a nail cylinder and a nail anvil which can perform relative motion, wherein a plurality of nail forming grooves are arranged on the nail anvil; a cartridge is fixed on the front end of the nail cylinder, the inside of the nail cylinder is provided with a nail-pushing plate, the nail-pushing plate is butted with nails in the cartridge and can push the nails out of the cartridge and fit with the nail forming grooves to form the nails on the tissue; the nail anvil is formed by connecting two semi-rings in a demountable manner; when the entire nail anvil is combined, a round through-hole extends from the top surface of the nail anvil to the inside, and the tissue can penetrate through the round hole to cover the top surface. The beneficial effect of the invention is mainly that the round pipe type stapling apparatus can satisfy the operations with smaller operation space such as high-position esophageal operations and low-position colorectal operations, thus expanding the application range of the round pipe type stapling apparatus and providing convenience for the doctor.

Description

technical field [0001] The invention relates to a binding instrument used in surgical operations, in particular to a circular tube binding instrument suitable for high esophagus surgery, belonging 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 tissue is easier t...
