Abstract

The invention relates to the technical field of cutting anastomats, and discloses a one-time forming linear cutting anastomat. The one-time forming linear cutting anastomat comprises an executing end and a striking end, wherein the executing end is connected with the striking end through a connecting pipe, a suturing assembly and a cutting blade are arranged in the executing end, a detection assembly is arranged at the tail of the cutting blade, the suturing assembly comprises two-stage suturing, and the two-stage suturing comprises first-stage suturing and second-stage suturing. According to the invention, by means of a pressing plate located between an anastomosis nail and a compensation nail, when the nail pushing block moves forwards to trigger the anastomosis nail, the pressing plate is extruded out of a nail bin to press tissue, and then a detection assembly scans cutting anastomosis effect and judges that the cutting anastomosis effect is good, so a nail pushing block can be retracted; under the action of a reset spring, the pressing plate is reset and the pressed tissue released; and when the detection assembly scans the cutting anastomosis effect and judges that the cutting anastomosis effect is not good, the pressing plate presses the cut tissue, so a wound is prevented from being cracked when the tissue fails to be sutured for one time.

Description

technical field

[0001] The invention relates to the technical field of cutting staplers, in particular to a linear cutting stapler for one-time forming. Background technique

[0002] Linear cutting stapler is a kind of endoscopic cutting stapler suitable for minimally invasive surgery. Its executive component is a kind of staple that can be arranged in a straight line on human tissue, and at the same time, it will be inserted with a cutting knife. The instrument for cutting tissue between the staple lines is also one of the instruments widely used in minimally invasive surgery, mainly used for tissue resection, transection and anastomosis in open or endoscopic surgery of abdominal surgery, gynecology, pediatrics and thoracic surgery .

[0003] In the existing structure, the trigger of the cutting stapler needs to be continuously pulled, and the reset button of the cutting stapler needs to be pulled. Since the firing and reset of the cutting stapler are both manual operation...
