Abstract

The invention discloses a nail bin assembly. The assembly comprises a nail bin body and anastomotic nails. The nail bin body comprises a top end surface, a nail pushing groove and nail cavities; and the anastomotic nails are positioned in the nail cavities, and each nail cavity penetrates the top end surface to form a nail outlet. The assembly is characterized in that: the height of the top end surface far from the nail pushing groove is lower than the height of the top end surface close to the nail pushing groove; and the outer side of the top end surface is provided with grooves with an outward opening. The nail bin assembly and a surgical instrument thereof can turn the anastomotic nails with the same size and shape into nail lines with different nail heights to be applied to tissues while cutting the tissues, so that the flow of tissue fluid at the target tissues is accelerated, the time for compressing the tissues to a specified height is effectively shortened, the operation timeis shortened, the situation of insufficient tissue squeezing is avoided, and the forming effect of the anastomotic nails is further ensured.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a staple cartridge assembly and a surgical instrument thereof, belonging to the field of medical instruments. Background technique [0002] Surgical cutting and stapler is a surgical instrument that can suture the patient's wound while removing excess tissue. It is widely used in the excision and anastomosis of tissues in minimally invasive operations such as abdominal surgery, gynecology, pediatrics, and thoracic surgery. The surgical cutting stapler enters the patient's body through the cannula of the puncture device precisely positioned at the surgical site. The surgical cutting stapler includes an end effector. The end effector includes a staple cartridge seat and an anvil seat. The staple cartridge seat is used to receive nails The cartridge assembly includes a staple cartridge body and staples arranged in the staple cartridge body. [0003] Place the target tissue between the stapl...
