Background
The existing cutting anastomat is divided into manual driving and electric driving, wherein in order to facilitate the medical staff to operate the cutting anastomat to operate on patients, the electric driving of the cutting anastomat of the executing assembly is the first choice of the medical staff; however, in the current cutting anastomat driven by electric power, because the driving mechanism is simple, when cutting and suturing, a user needs to judge the thickness of a cut tissue of a patient before an operation, and medical staff usually judges the thickness according to clinical experience, and due to the difference of the cut tissues and the difference of patient objects, misjudgment is easily caused.
When the thickness of the tissue is judged to be too thick, the tissue is clamped by the cutting anastomat, so that the tissue is excessively clamped, and the clamped part of the tissue is necrotized; when the tissue is too thin, the tissue is clamped by the cutting anastomat, so that the tissue is too shallow to be clamped, the tissue of the clamped part is loose, and at the moment, when the cutting anastomosis is performed again, shrinkage of the cut tissue is caused by the tension of the cut tissue (wherein the thicker the tissue is, the larger the tension generated after the lamination of the tissue); when the distance between the nail bin and the nail supporting seat is larger than the thickness of the tissue, the anastomotic nail is formed, the tissue incision cannot be completely closed, meanwhile, the tissue has certain tension, the tissue incision can be further expanded or inwards rolled (the rolling degree is different due to different tissue thicknesses, and generally, the thicker the tissue is, the larger the rolling degree is), and the healing after the tissue cutting anastomosis is affected; wherein, because thicker tissues can be extruded outwards after being flattened, after the suturing is finished, the tissues can be contracted when released, and the bleeding phenomenon of the tissue cutting and suturing position can be caused.
