The invention provides a cutting stapler reset by a single hand, relating to the technical field of a stapler. The cutting stapler comprises a shell, a retaining mechanism, a releasing plate and a resetting mechanism, wherein a driving mechanism is arranged in the shell; the driving mechanism comprises a trigger, a driving rod and a driving plate connected between the trigger and the driving rod; the retaining mechanism comprises a U-shaped support, a retaining plate and a retaining spring; the U-shaped support is fixedly arranged in the shell; the retaining plate is obliquely installed in the U-shaped support; the retaining spring sheaths the driving rod, and causes the retaining plate to be kept in an oblique state; a retaining hole for the passing of the driving rod is formed in the retaining plate; the releasing plate is arranged on the shell, and can rotate; a releasing piece for correcting the retaining plate is arranged on the releasing plate; the resetting mechanism comprises a downward pressing component arranged on the rear end of the driving rod, and a resetting button connected with the downward pressing component; when the resetting button is pulled back, the downward pressing component drives the releasing plate to rotate. According to the cutting stapler, the past resetting by double hands is changed to reset by the single hand; therefore the operation flow is simplified, and the surgical time is shortened.
Description
technical field [0001] The invention relates to the technical field of staplers, in particular to a one-hand reset cutting stapler. Background technique [0002] The endoscopic cutting stapler and its executive components suitable for minimally invasive surgery are a kind of staples that can be arranged in a straight line on the human tissue, and at the same time, the tissue between the staple lines is cut with a cutting knife. The cutting instrument is also one of the instruments widely used in minimally invasive surgery. It is mainly used for tissue resection, transection and anastomosis in open or endoscopic surgery of abdominal surgery, gynecology, pediatrics and thoracic surgery. [0003] The Chinese invention patent "Cutting Stapler Suitable for Minimally Invasive Surgery" application number is CN201310263622.9 discloses a surgical instrument, the cutting stapler suitable for minimally invasive surgery can be connected with an executive component, after the instrument ...
