Embodiment Construction

[0013] Such as figure 1 Shown is the linear stapler, the tubular stapler can be fully referred to figure 1 .

[0014] In the figure: 1-location button; 2-bow frame; 3-fastening nut; 4-outer sleeve; 5-return spring; 6-slider; 7-left handle; 8-right handle; 9-axis screw; - safety button; 11 - tail screw button; 12 - adjusting screw; 13 - plastic component; 14 - pushing nail plate; 15 - component frame; 16 - pressure sensing sheet.

[0015] The prior art has disclosed gastrointestinal anastomosis-mechanical suture method (stapler method), and the method of using gastrointestinal stapler to perform gastrointestinal surgery can also be called stapler type gastrointestinal anastomosis (sewing) technique . Intestinal staplers include LDS (Ligating-Dividing Stapling), which is used to ligate and separate mesangial and omental blood vessels; TA (Thoracic-Abdominal) is used for suturing the gastrointestinal tract; GIA (Gastro-Intestinal Anastomosis) is used for gastrointestinal tract...

Abstract

The invention discloses a cutting stapler and an anastomat with a pressure sensing function and an automatic adjusting device. Pressure values can be conducted and displayed via set pressure sensors when an anastomosis nail side of the anastomat and a nail butting seat are in direct or indirect contact with each other. The pressure sensors are mounted on an optional side of the anastomosis nail side and an optional side of the nail butting seat or on two sides of the anastomosis nail side or two sides of the nail butting seat, and the pressure values are displayed via shaping and amplifying circuits and display circuits of the pressure sensors. The cutting stapler and the anastomat with the pressure sensing function and the automatic adjusting device have the advantages that the anastomosis quality can be guaranteed, and post-anastomosis complications of anastomotic bleeding and anastomotic leakage of gastrointestinal tract can be eliminated to the greatest extent.

Description

technical field [0001] The present invention relates to the structure of a stapler for surgical operations. Background technique [0002] When performing gastrointestinal anastomosis and cutting and closing, anastomotic bleeding and anastomotic leakage are serious surgical complications. During anastomosis), the pressure between the distal end and the proximal end is too large, too small or uneven, and the pressure is too small (the two layers of tissue are not fit enough) may lead to incomplete anastomosis or incomplete hemostasis at the anastomosis, and anastomotic leakage and Anastomotic bleeding; excessive pressure (high pressure between two layers of tissue) will lead to ischemic necrosis of the anastomotic, resulting in anastomotic leakage and anastomotic bleeding; uneven pressure may cause incomplete anastomosis in some parts, and incomplete anastomosis in some parts Ischemic necrosis leads to bleeding and anastomotic leakage. These complications may lead to anastomo...
