Embodiment 1

[0029] like image 3 As shown, the present embodiment provides a stapler with a staple cartridge guided into staples, such as Figure 4 As shown, the above-mentioned staple cartridge has a plurality of nail grooves 1, and a staple is placed in the above-mentioned nail groove 1, and an example of the staple is as follows Image 6 Staple 2 shown, cartridge above Figure 4 Partial enlarged picture of Figure 5 As shown, the surface at one end of the above-mentioned nail groove 1 has a first boss 11 and a fourth boss 14, and the distance between the first boss 11 and the fourth boss 14 is the diameter of the above-mentioned staple or greater than The diameter of the staple is such that one end of the staple slides between the first boss 11 and the fourth boss 14 . The above design of the boss not only increases the guiding effect on the staples, but also increases the clamping force of the instrument on the tissue.

Abstract

The invention provides a stapling device provided with a staple cartridge capable of guiding molded staples. The staple cartridge is provided with a plurality of staple grooves, wherein suturing staples are placed in the staple grooves; a first boss and a fourth boss are arranged on the surface of one end of each staple groove; and distances between the first bosses and the fourth bosses are identical to or greater than diameters of the suturing staples, so that one end of the suturing staples can slide between the first bosses and the fourth bosses. According to the technical scheme, the stapling device provided by the invention is simple and reliable; good flatness of suturing staple molding is guaranteed, and meanwhile, the suturing staples are easier to mount; the staple cartridge corresponding to a staple anvil has a guiding characteristic, so that a relatively good suturing staple molding effect is guaranteed; and through the bosses on the surfaces of the staple grooves, clampingforce of the stapling device to tissues is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a stapler with a staple cartridge guided into staples. Background technique [0002] The principle of the medical stapler is that in a surgical operation, several rows of staples are stapled to the tissue to be sutured by an instrument similar to a stapler, so as to replace the original sutures and needles for suturing, with short suturing time, Even suture, good healing effect and so on. [0003] In terms of staple forming technology, the nails formed on the anvil are pushed out by the staple pusher. When the staples are pushed out of the nail grooves, they may be offset by the extrusion and repulsion of the suture tissue at the beginning, and eventually become as figure 1 poor shape as shown, thus creating a defect in use. [0004] Covidien invented the DST technology, one of its technical principles is an error-tolerant (or error-correcting) anvil groove and flat staples. Thi...
