Embodiment 1

[0036] Such as Figure 1 to Figure 7 As shown, a disposable nail magazine for a minimally invasive cutting stapler includes a nail magazine base 12, the front end of the nail magazine base is rotatably equipped with a nail bin 2, and the front end of the nail magazine base is fixedly installed with a An abutment base 3 corresponding to the upper and lower sides of the nail magazine 2, or a nail magazine 2 is fixedly installed on the front end of the nail magazine base, and a nail abutment base 3 corresponding to the upper and lower sides of the nail magazine base is installed on the front end of the nail magazine base ; The front end of the staple cartridge is provided with a boss 4, or the boss is provided on the anvil. Such as Figure 8 As shown, after the jaws 9 are closed, in the process of suturing and cutting, the boss can clamp the target tissue 10 more tightly, and prevent the target tissue 10 from slipping and slipping from the jaws; thereby effectively ensuring cutt...

Embodiment 2

[0047] Such as Figure 14 , Figure 15 and Figure 16 As shown, the technical solution of the second embodiment is basically the same as the technical solution of the first embodiment, the difference is that: the front end of the nail anvil 3 is riveted with a separation hook 18, and the front end of the separation hook 18 faces toward the nail anvil. The lower front of the seat extends, so that the separation hook extends obliquely toward the base of the nail box. The lower surface of the separation hook 18 is provided with a snap-in groove 19, and the snap-in groove 19 is provided with a rivet 20. The front end of the anti-nail seat 3 is provided with a snap-in protrusion 21 that cooperates with the snap-in groove 19, and the snap-in protrusion 21 is provided with a riveting hole 22 that cooperates with the rivet 20, and the separation The rear end of the hook 18 is a horizontal section. When the nail anvil is closed in the nail bin, the rear end of the separation hook 18 ...

Abstract

The invention discloses a disposable nail box used for a minimally invasive cutting anastomat. The disposable nail box comprises a nail box base, wherein a nail cartridge is fixedly mounted at the front end of the nail box base, a nail propping base corresponding to the nail cartridge vertically is rotatably mounted at the front end of the nail box base, or, the nail cartridge is rotatably mountedat the front end of the nail box base, and the nail propping base corresponding to the nail cartridge vertically is fixedly mounted at the front end of the nail box base; a boss is arranged at the front end of the nail cartridge, or the boss is arranged on the nail propping base; after a jaw is closed, during the suturing and cutting processes, the boss part can tightly clamp a target tissue, thus the target tissue is prevented from slipping and sliding off the jaw, and therefore, the surgical quality of cutting and suturing is effectively guaranteed.

Description

technical field [0001] The invention relates to a disposable nail box for a minimally invasive cutting stapler. Background technique [0002] In surgery, minimally invasive surgery only needs to cut 3 to 5 small incisions on the patient's body, insert instruments with slender rods into the body to cut and suture the diseased tissue, and then remove the excised diseased tissue Take it out from the narrow channel. Minimally invasive surgery has the advantages of less local trauma, less systemic reaction, and faster postoperative recovery. So it has been widely used. [0003] Minimally invasive cutting stapler is a surgical instrument used in minimally invasive or open surgery to resect, transect and suture the lung, bronchial tissue, stomach, intestine, etc. When in use, a replaceable disposable nail box is connected to the front end of the body. One instrument is used for one operation, and several disposable nail magazines are used instead according to the needs of the o...
