Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] Herein, "upper", "lower" and the like are only used to indicate the relative positional relationship between related parts, rather than to limit the absolute positions of these related parts.

[0044] Unless otherwise stated, a numerical range herein includes not only the entire range within its two endpoints, but also several subranges subsumed therein.

[0045] The end of each of the following components close to the operator is defined as the proximal end, ...

Abstract

The invention discloses a stapler. The stapler comprises an assembly inner core and a gun block inner core, wherein a proximal end of the assembly inner core is provided with two axisymmetric limiting blocks, a distal end of the gun block inner core is provided with two corresponding axisymmetric limiting grooves, and the proximal end of the assembly inner core and the distal end of the gun block inner core are subjected to snap-fit connecting through the limiting blocks and the limiting grooves so as to achieve primary fixing; and the gun block inner core comprises a safety connecting mechanism, the safety connecting mechanism is located on the surface of the external wall of the gun block inner core, can at least partially slide to the outside surface of the assembly inner core along the outside surface of the gun block inner core, and is used for locking the assembly inner core and the gun block inner core so as to form secondary fixing. According to the stapler, the safety connecting mechanism of the gun block inner core slides back and forth between the gun block inner core and the assembly inner core so as to control locking and unlocking of the assembly inner core and the gun block inner core, thus, the assembly inner core and the gun block inner core achieve the secondary fixing, the connecting is firmer, and the risk of falling-off is lowered greatly.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stapler. Background technique [0002] With the development of modern technology and the improvement of medical standards, surgical instrument staplers have gradually become medical equipment used to replace traditional manual suturing. The main working principle is to use titanium nails to separate or anastomose the lesion tissue, similar to stapling. machine. [0003] At present, laparoscopic staplers are playing an increasingly important role in minimally invasive surgery. Due to the different thicknesses and lengths of cut and stapled tissues, when cutting and anastomating the surgical site, it is necessary to select the corresponding type of components. The components and the gun body are quickly assembled. When the gun body and the components of the existing endoscopic stapler are assembled, the components and the gun body are not inserted firmly, so there is a risk of...
