Abstract

The invention discloses a sandwiched stapler type alimentary tract anastomosis dissecting sealer, relating to the surgical instruments. The invention provides a sandwiched stapler type alimentary tract anastomosis dissecting sealer which can prevent the alimentary tract anastomotic stoma from tearing, leaking and errhysis from the cut section in surgical operations. The sandwiched stapler type alimentary tract anastomosis dissecting sealer is provided with a nail anvil (which is also called as a bottom needle holder), a nail cartridge (which is also called as a nail anvil box), a sealer body, a movable handle, an adjusting button, a cutter cushion and an anastomosing nail (which is also called as a suturing nail), wherein the nail anvil is connected with the front end of the sealer body, the adjusting button is arranged at the tail part of the sealer body, the movable handle is arranged at the back of the sealer body, a safety button is arranged at the connection of the movable handle and the sealer body, the cutter cushion is arranged on the nail anvil, the anastomosing nail is arranged at the front end part of the sealer body, a membrane is arranged on the surface of the nail anvil (which is also called as the bottom needle holder), and a membrane is also arranged on the surface of the nail cartridge (which is also called as the nail anvil box); and after stapling, a sandwich structure consisting of the membrane, an intestinal wall and the membrane is formed.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a sandwich stapler type digestive tract anastomosis cutting closure mainly used for digestive tract and other surgical operations. Background technique [0002] In digestive tract surgery, it is often necessary to reconstruct and suture the digestive tract, and it is necessary to remove the excess tissue of the viscera after butt joint suture in order to reconstruct the digestive tract. In order to ensure the smooth completion of the above operations, a disposable digestive tract stapler is usually used , the design principle of the currently used surgical instrument "disposable digestive tract stapler" usually adopts the stapler principle, and there are two types of tube type and linear type. Also known as staple box), device body, movable handle, adjustment button, knife pad and staples (also known as staples), etc., it is also equipped with a connecting rod for cutter stapler. During ...
