Tissue closure component and medical device equipped with the tissue closure component

Abstract

The invention discloses a tissue closure assembly. The tissue closure assembly comprises a tissue closure device, wherein the tissue closure device comprises a base, a pressure plate matched with the base, a screw pushing block and a cutting knife which is assembled on the tissue closure device and capable of being selectively separated from or matched with the screw pushing block; the screw pushing block comprises an initial position located at the near end of the base, a screw closure position located at the far end of the base and a pulling-back position; the pulling-back position is located between the initial position and the screw closure position, and the screw pushing block is separated from the cutting knife when in the initial position and is matched with the cutting knife when in the screw closure position; the tissue closure device further comprises a screw accommodating part arranged at the far end of the base and used for accommodating the cutting knife, when the screw pushing block moves towards the pulling-back position from the screw closure position, the screw pushing block is matched with the cutting knife to drive the cutting knife to move from the far end to the near end of the base and cut off tissue. The tissue closure assembly is easy to operate and convenient to use, and further reduces the surgical cost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tissue closure component and a medical device equipped with the tissue closure component. Background technique [0002] In the existing anastomosis of the digestive tract, it is generally first to use a linear or arc-shaped stapler to separate and anastomose the tubular organ, and then to use a round-shaped stapler to perform butt anastomosis on the severed tissue. In this way, when a linear or arc-shaped stapler is used to anastomose a tubular organ, since the anastomosis is linear, there will be cat ears when the circular stapler is used for anastomosis, and there is a risk of fistula. Surgery costs are high. Contents of the invention [0003] The purpose of the present invention is to provide a tissue closure component and a medical device equipped with the tissue closure component. [0004] In order to achieve one of the objectives of the above invention, an emb...
