Problems solved by technology

[0003] The device operates by clamping the human tissue on the upper wall of the nail box (6) on the nail box arm and the lower wall of the nail anvil on the nail anvil arm. (62) When advancing forward, the human tissue is easily slipped under the forward cutting force, which affects the suture quality

Embodiment Construction

[0015] see figure 2 , 3 , 4. This example is a nail magazine for a surgical linear cutting stapler. The upper wall of the nail magazine is provided with a cutting groove 62 coincident with the longitudinal central axis, and three rows of longitudinal nail outlets are respectively provided on both sides of the cutting groove to communicate with the lower nail magazine. The openings 61, the adjacent nail outlets between the rows are arranged in a staggered manner, and the nail outlets on both sides of the cutting groove are symmetrical to each other.

[0016] On the upper wall of the nail box, there are several transverse grooves 63 parallel to each other to form a longitudinal convex-concave anti-slip surface. Since the cutting knife moves longitudinally, the tissue can be prevented from sliding longitudinally. The grooves are respectively arranged in the nail outlet holes. In this way, the tissue clamped at the suture point can be better positioned and the sutured tissue can...

Abstract

The invention relates to a skidproof nail box of a surgical linear cutting stapler, which is provided with a nail box (6), wherein the upper wall surface of the nail box is provided with a longitudinal cutting groove (62) and the two sides of the cutting groove are respectively provided with a nail outlet hole. The skidproof nail boxis characterized in that the upper wall surface of the nail box is provided with a skidproof convex-concave surface. The skidproof convex-concave surface can effectively prevent human organisms from skidding in an operation process, thereby ensuring surgical cutting and suturing quality.

Description

technical field [0001] The invention belongs to a medical device, in particular to a linear cutting stapler for surgical operations. Background technique [0002] The main structure of surgical linear cutting stapler is (see figure 1 ): The instrument is equipped with an anvil arm (4) and a magazine arm (3) in the shape of a cross jaw controlled by a hand-held upper handle (1) and a lower handle (2). Cassette (6), the rear part is equipped with a nail pushing part that can move forward under the action of the firing device (10) to push the titanium nails to the direction of the nail anvil arm through the nail pusher in the nail box, and push the cutting knife along the nail box Cutting slot (62) moves forward the push knife bar, the nail anvil arm is provided with the nail anvil relative to the nail box, and its working process is: earlier use the nail anvil arm (4) of cross jaw shape and the nail box arm ( 3) Clamp the human tissue to be sutured, and use the upper and low...
