Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 making creative efforts belong to the protection scope of the present invention.

[0030] The core of the present invention is to provide a magazine nail assembly of a linear stapler, which can effectively reduce the firing force of the stapler, alleviate the fatigue of doctors during operation, and optimize the stapling effect.

[0031] Please refer to Figure 1 to Figure 8 , figure 1 It is a schematic diagram of a specific embodiment of the staple cartridge assembly of the linear stapler provided by the present invention; figure 2 It is...

Abstract

The invention discloses a nail bin assembly of a linear anastomat. Three rows of upper nail cavities and three rows of lower nail cavities are distributed on the upper half portion and the lower halfportion of a nail bin in a staggered mode. Therefore, the maximum force borne by nail pushing particles inserted into the nail cavities in the nail forming process is mutually staggered; the first nail pushing particles are inserted into the first row of nail cavities and the second row of nail cavities at the same time; the second nail pushing particles are inserted into the third row of nail cavities; the gradient of the first inclined surface used for pushing the first nail pushing particles is smaller than that of the second inclined surface used for pushing the second nail pushing particles; therefore, under the condition of generating the same upward thrust, the thrust can be ensured to be uniform; the forward pushing force of the nail pushing block is small; besides, the highest points of the first inclined surface and the second inclined surface on the nail pushing block are staggered; the time for the first nail pushing particle and the second nail pushing particle to reach the highest point can be staggered, the situation that three rows of suturing nails reach the highest point at the same time is avoided, and therefore thrust needed by the nail pushing block is furtherreduced, the whole suturing process is more stable, surgical fatigue of doctors is relieved, and the suturing effect is optimized.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, to a staple cartridge assembly of a linear stapler. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. It is mainly used for the closure of stumps or incisions in digestive tract reconstruction and organ resection under endoscopy. It is suitable for a variety of open or minimally invasive general surgery, obstetrics and gynecology, urology, thoracic surgery and pediatric operations. They can be used with staple wire or tissue support material. [0003] Due to the development of modern science and technology and the improvement of production technology, the staplers currently used clinically are reliable in quality, easy to use, tight, and suitable for tightness, especially their advantages such as fast suturing, easy operation, and few side effects and surgical complications. It enables the surgery of tumors that wer...
