Example Embodiment

[0043] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0044] The cutting suture device of the present invention includes a jaw assembly, a connecting assembly connected to the jaw assembly, a jaw driving assembly, a handle assembly, a housing 1 and a cutting device. For convenience, in the following description, the end far away from the operator (that is, the end close to the nail seat) is called the front end, and the end close to the operator (that is, the end close to the fixed handle) is called the rear end.

[0045] Such as Figure 1-3 As shown, the jaw assembly includes a nail abutment base bracket 2, a nail abutment base 3 arranged at the front end of the nail abutment base bracket 2, a nail cartridge 4, and a nail cart...

Abstract

The invention relates to a forceps opening assembly with a guiding structure and a stitching instrument adopting the forceps opening assembly. The forceps opening assembly comprises a nail pressing seat bracket 2, a nail pressing seat 3, a nail cabin bracket 5 and a nail cabin 4; a first chute 6 is formed at the middle lower part of the nail pressing seat bracket 2; a dovetail slide rail 7 is arranged at the upper part of the rear end of the nail pressing seat bracket 2; a second chute 8 is formed at the top part of the rear end of the nail cabinet bracket 5; the lower end of the nail cabinet 4 is arranged in the first chute 6 in a sliding manner; and the slide rail 7 is arranged in the second chute 8 in a sliding manner. The stitching instrument further comprises a cutting device. In the invention, the forceps assembly with the guiding structure can effectively prevent the nail cabinet from running out in the closing process of the forceps assembly; the adopted cutting device can easily realize full separation of tissues; meanwhile, the removable forceps assembly can satisfy the requirements of the stitching instruments with different suture lengths in a same operation, such that manufacturing cost and operation cost of the stitching instrument can be saved.

Description

technical field [0001] The invention relates to a medical device, in particular to a jaw assembly with a guiding structure and a stapler using the jaw assembly. Background technique [0002] In the surgical operation of medical science, since the first staple product of the utility model in the 1960s, the medical stapler has become an indispensable medical device in the process of suturing the knife edge. Various surgical staplers are widely used in surgical operations to suture human digestive tract tissues, respiratory tract tissues and vascular tissues, which can reduce operation time and improve operation quality. They are usually used for end-to-end, end-to-side, and side-to-side suture operations such as esophagus, stomach, duodenum, small intestine, colon, and rectum in the digestive tract, or operations for forming channels or closing incisions such as hemorrhoidectomy and gastric pylorostomy. It is used in the suture operation of the lung and trachea in the respira...
