Gastrointestinal electric cutting anastomat

Abstract

The invention relates to the technical field of electric anastomats, and discloses a gastrointestinal electric cutting anastomat which comprises a driving mechanism, an execution end and a driving handle, the driving mechanism is located in the driving handle, the execution end is located at the end away from the driving handle, the driving mechanism is used for driving the execution end, and the execution end comprises a nail bin and a nail abutting base. A detector is arranged in the nail bin and the nail abutting base and used for detecting the tissue thickness when the nail bin and the nail abutting base are closed. By means of a switching locking assembly, the anastomosis nails of different specifications can be flexibly used for suturing the skin, when thick tissue is sutured, the switching locking assembly is used for changing the connection relation between an installation piece and a main anastomosis piece and the connection relation between the installation piece and the nail bin, then the main anastomosis piece is switched between sutured tissue and fixed tissue, and therefore, the suture of thicker or thinner tissues can be met.

Description

technical field [0001] The invention relates to the technical field of electric staplers, in particular to an electric gastrointestinal cutting stapler. Background technique [0002] Most of the existing cutting staplers are divided into manual drive and electric drive. Among them, in order to facilitate the medical staff to operate the cutting stapler to operate on the patient, the cutting stapler with the electric drive actuator is the first choice for the medical staff; Due to the simple driving mechanism of the driven cutting stapler, the user needs to judge the thickness of the patient's cut tissue before the operation when cutting and suturing. Medical staff usually judge the thickness based on clinical experience. The difference can easily lead to misjudgment. [0003] When the judgment of tissue thickness is too thick, when the cutting stapler clamps the tissue, it will cause excessive clamping of the tissue, causing necrosis of the clamped part of the tissue; when ...

[0002] Most of the existing cutting staplers are divided into manual drive and electric drive. Among them, in order to facilitate the medical staff to operate the cutting stapler to operate on the patient, the cutting stapler with the electric drive actuator is the first choice for the medical staff; Due to the simple driving mechanism of the driven cutting stapler, the user needs to judge the thickness of the patient's cut tissue before the operation when cutting and suturing. Medical staff usually judge the thickness based on clinical experience. difference, which can easily lead to misjudgment

[0003] When the judgment of tissue thickness is too thick, when the cutting stapler clamps the tissue, it will cause excessive clamping of the tissue, causing necrosis of the clamped part of the tissue; when the judgment of tissue thickness is too thin, when the cutting stapler clamps the tissue, it will cause The clamping of the tissue is too shallow, so that the clamped part of the tissue is loose. At this time, when the cutting and anastomosis are performed again, the tissue after cutting will shrink due to its tension (the thicker the tissue, the tension generated after pressing will be smaller. larger); and when the distance between the staple cartridge and the anvil is greater than the thickness of the tissue, the staple is formed, and the staple cannot completely close the tissue incision, and there is still a certain tension in the tissue. At this time, the tissue incision will be closed. Further expansion or inward rolling (where the thickness of the tissue is different, the degree of rolling is also different, generally the thicker the tissue, the greater the degree of rolling), which affects the healing after tissue cutting and anastomosis; among them, because the thicker tissue will be flattened External extrusion, after the suture is completed, tissue shrinkage will occur when the tissue is released, causing bleeding at the tissue cutting suture
