Surgical linear cutting anastomatTechnical Field
The invention relates to the field of medical instruments, in particular to a surgical linear cutting anastomat.
Background
The anastomat is the first stapler in the world and is used for gastrointestinal anastomosis for nearly a century, and the tubular anastomat is not widely used for gastrointestinal surgery until 1978; generally, the anastomat is divided into a disposable anastomat or a multi-use anastomat, an imported anastomat or a domestic anastomat; the anastomat is equipment used for replacing the traditional manual suturing in medicine, and due to the development of modern science and technology and the improvement of manufacturing technology, the anastomat used clinically has reliable quality, convenient use, tightness and proper tightness, particularly has the advantages of quick suturing, simple and convenient operation, few side effects, few operation complications and the like, and can also be used for excising the focus of a tumor operation which cannot be excised in the past;
however, the conventional stapler has the following disadvantages:
in the process of operating on internal tissues of a human body, the traditional anastomat cannot temporarily and quickly change the angle of the end head of the anastomat, so that a doctor needs to adjust the direction of the anastomat outside the human body, the angle adjusting operation is very inconvenient in this way, and an instrument body is dragged and moved, so that other tissues in the human body can be seriously damaged; in addition, when the conventional anastomat is used for surgery, the suturing nail in the conventional anastomat can be accidentally dropped, so that a plurality of surgical risks are caused.
