Description
Technical Field
The invention relates to a clamping anastomat of a disposable endoluminal anastomat, which is matched with the disposable endoluminal anastomat for use, and is particularly suitable for the disposable endoluminal anastomat for applying a line row on an endoluminal tissue.
Background
Traditional surgical procedures include cutting, separation, ligation, hemostasis, suturing, and ultimately achieve excision of organ lesions and reconstruction of organs. The mechanical suture device can replace the traditional operation, and the excision and reconstruction of the lesion organ can be realized through the following three basic operations: 1. and (3) partition: that is, the linear suture device is used to suture the organ at a certain distance from the lesion, including the parenchymal organ, the luminal organ, the blood vessel, etc., and then the lesion organ is excised, or the linear cutting suture device is used to complete the suture and the excision at one time. 2. I.e., apposition of the tissue to be sutured, stapling with a linear stapler, such as slitting a transverse seam at the pylorus, to complete the pyloplasty. 3. By using the annular anastomat, the end-to-end anastomosis of the luminal organs such as esophagus, stomach, small intestine and colon can be conveniently performed. Gastrointestinal side anastomosis can be performed using a cutting stapler. Such as colorectal end anastomosis, esophageal gastric end side anastomosis, gastric jejunal side anastomosis, and the like.
In laparoscopic and/or endoscopic surgical procedures, the procedure is performed through a small incision or a narrow cannula inserted into a wound in the patient. In conventional or open procedures, the surgeon directly contacts the surgical site. Because of its reduced patient trauma, reduced patient recovery and significantly reduced overall cost, abdominal surgery is advantageous over open surgery. To accommodate the specific needs of both endoscopic and laparoscopic surgical procedures, endoscopic suturing devices have been developed to provide easy access to the surgical site by the surgeon. Typically, these stapling instruments include an articulatable tool member supported proximate the end of the stapling apparatus. The tool component may be selectively manipulated to enable a surgeon to manipulate the surgical device in a confined space. These instruments provide significant medical benefits to endoscopic procedures. Nevertheless, improvements in cost reduction and manufacturing complexity are still desirable.
At present, in the endoluminal incision anastomat, both hands are required to operate, doctors do not operate smoothly enough, plastic pieces are arranged inside the endoluminal incision anastomat, and the intensity is insufficient, so that operation failure can be caused.
