Embodiment Construction

[0025] The invention discloses a circular tube binding instrument. Such as figure 1 As shown, the existing circular tube type bookbinding instrument includes a nail bin 2, a nail barrel 1 and a hollow connecting pipe 3 which are fixedly connected to each other in sequence; A press-fit joint 13 is provided between the hollow connecting pipes 3 .

[0026] The nail barrel 1 includes a circular hole 8 for accommodating resected tissue, and a central hole 4 communicating with the circular hole 8 . The inside of the nail barrel 1 is movably provided with a nail pushing piece 6 , and a nail anvil pull rod 5 moves in the center hole 4 . Because the sealing performance of the existing circular tube type binding instrument is not good, after the gas enters from the circular hole 8, it can figure 1 Flow in the direction of the middle arrow, escape from the snap joint 12, the joint 13, or enter the hollow interior of the connecting pipe 3 through the gap between the nail pusher 6 and t...

Abstract

The invention provides a round tube type binding instrument. The instrument comprises a nail bin, a nail barrel, a hollow connecting tube, and a sealing film sleeve with a closed end, wherein the sealing film sleeve comprises a planar body and a circumferential body; and in a semi-closed space formed when the nail bin and the nail barrel are accommodated in the sealing film sleeve, the outline of the circumferential body of the sealing film sleeve is consistent with the outline of the nail bin and the outline of the nail barrel, and the circumferential body covers at least one part of the connecting tube. The sealing film sleeve can be contracted and cover the nail bin, the nail barrel and the connecting tube to achieve a sealing effect only by making the round tube type binding instrument sleeved with the sealing film sleeve quickly pass through an oven. The invention has the main advantages that: the round tube type binding instrument has high sealing property and can be well applied to minimally invasive surgeries, and a sealing mode of the instrument is also extremely simple and convenient.

Description

technical field [0001] The invention relates to a circular tube type binding instrument with better sealing performance and a sealing method thereof, belonging to the field of medical instruments. Background technique [0002] The circular tube binding instrument for surgery is a medical device that is often used when suturing and cutting physiological tissues such as esophagus and intestinal tract. Its performance directly affects the operation process and plays a very important role in the operation effect. In the prior art, as disclosed in U.S. Patent No. 5,205,459, the circular tube-type binding instrument is generally composed of a body with a firing handle and a binding head with a sewing device. Composed of hollow connecting pipes. The inside of the nail barrel is movably provided with a nail pushing piece, and an anvil pull rod moves in the center hole provided on the nail barrel for connecting with the nail anvil assembly. [0003] The current round tube binding i...
