Description
Technical Field
The invention relates to the technical field of electric anastomats, in particular to a gastrointestinal electric cutting anastomat.
Background
Most of the existing cutting anastomats are manually driven and electrically driven, wherein the cutting anastomat of the electric drive executing assembly is the first choice of medical personnel for facilitating the medical personnel to operate the cutting anastomat to perform the operation on a patient; however, in the current cutting stapler driven by electric power, because the driving mechanism is simple, when cutting and suturing, a user needs to judge the thickness of the tissue cutting part of a patient before an operation, medical staff usually judges the thickness according to clinical experience, and because of the difference of the cutting tissue, the difference of the patient object is easy to cause judgment errors.
When the tissue thickness is judged to be too thick, the cutting anastomat clamps the tissue, the tissue is excessively clamped, and the tissue at the clamped part is necrotized; when the tissue is judged to be too thin, when the cutting anastomat clamps the tissue, the tissue is clamped to be too shallow, so that the tissue at the clamped part is loose, and when the cutting anastomat is used for cutting and anastomosis, the cut tissue shrinks due to the tension of the cut tissue (wherein the thicker the tissue is, the larger the tension generated after the tissue is pressed); when the distance between the nail bin and the nail abutting seat is larger than the tissue thickness, the formation of the anastomotic nails can cause that the anastomotic nails can not completely close the tissue incision, and meanwhile, the tissue has certain tension, and the tissue incision at the moment can be further expanded or inwards rolled (the tissue thickness is different, the rolling degree is also different, generally, the thicker the tissue is, the larger the rolling degree is), so that the healing of the cut and anastomosed tissue is influenced; wherein, because the thicker tissue can be extruded outwards after being squashed, after the suture is finished, the tissue can be shrunk when being released, and the bleeding phenomenon can occur at the position of the tissue cutting suture.
