Occlusion device for linear excision anastomat for surgical department

Abstract

The invention discloses an occlusion device for a linear excision anastomat for a surgical department. The occlusion device comprises a nail butting base, an assembly base, a nail butting base frame, an occlusion lead screw and a driving rod, wherein one end of the occlusion lead screw is connected with an occlusion knob, and the other end of the occlusion lead screw is provided with an occlusion nut in a movable mode; a driving pin is fixed on the occlusion nut; a first sliding chute matched with the driving pin is formed on the driving rod; two connecting rods are hinged on the nail butting base frame; an end of each connecting rod and the driving rod are hinged on a first pin shaft; the first sliding chute matched with the first pin shaft is formed on the nail butting base; a second pin shaft is also sleeved on the tail part of the nail butting base; and a second sliding chute matched with the second pin shaft is formed on the assembly base. By the occlusion device, the consistency of the occlusion height and inosculation height of apparatus on occlusion of physiological tissues is achieved, so the occlusion device can meet requirements of the physiological tissues with different thicknesses and ensures the surgical quality.

Description

technical field [0001] The invention relates to a closing device of a linear cutting stapler for surgery, which belongs to the field of medical instruments. Background technique [0002] At present, the linear cutting stapler is a medical device often used in surgical operations on physiological tissues such as the digestive tract, but when performing transverse anastomotic resection of stomach, lung and intestinal tissue, using the existing cutting stapler has the following problems: Disadvantages: When closing the compressed tissue during the operation, the front-to-back balanced closure is achieved by the preset scissors difference of the instrument. Obviously, for stomach, lung, and intestinal tissues of different thicknesses, the reaction force to the instrument is different. Because the front end of the instrument is a cantilever Design, the rigidity of the instrument is poor, for thicker tissues, the anvil seat will be warped and deformed, making the anastomotic heig...

[0002] At present, the linear cutting stapler is a medical device often used in surgical operations on physiological tissues such as the digestive tract, but when performing transverse anastomotic resection of stomach, lung and intestinal tissue, using the existing cutting stapler has the following problems: Disadvantages: When closing the compressed tissue during the operation, the front-to-back balanced closure is achieved by the preset scissors difference of the instrument. Obviously, for stomach, lung, and intestinal tissues of different thicknesses, the reaction force to the instrument is different. Because the front end of the instrument is a cantilever Design, the rigidity of the instrument is poor, for thicker tissues, the anvil seat will be warped and deformed, making the anastomotic height H of the front end larger, and it will also shift left and right, resulting in poorly formed staples, unable to anastomose the tissue effectively, and affecting the quality of the operation , which affects the safety of the operation; in addition, for different tissues to be anastomosed, due to individual or tissue differences, the anastomosis height is different. Once the device is selected, the closure height of the existing technology cannot be adjusted. Injured tissue, or the anastomosis height is too large, affecting the quality of surgery
