[0002] The stapler used in surgical operations is a surgical cutting stapler that can cut off excess tissue while suturing the patient's wound. It is widely used in the removal and anastomosis of tissues in minimally invasive surgeries such as abdominal surgery, gynecology, pediatrics and thoracic surgery. The surgical cutting stapler enters the patient's body through the cannula of the puncture device that is precisely positioned at the surgical site, and then makes a longitudinal incision in the tissue and applies staples on the opposite side of the incision, thereby cutting and anastomosing the tissue.

[0003] In the prior art, a linear cutting stapler disclosed in the patent with publication number CN211433103U is provided, which can automatically limit the position of the cutting knife after the cutting knife is retracted after firing through a driving handle, a release button, a hinge assembly, a cutting push button, a connecting rod, a safety locking assembly, a rotating pressure block, a rotating handle, a pressure block, an arc surface A, a chamfer A, a limit block, an inclined surface, a plane, a chamfer B, an elastic body, a vertical plate, a leaf spring, a flat plate, a nail anvil assembly, a nail magazine assembly, a nail groove, a cutting guide groove, a cutting knife groove, a fixed handle, a limit groove, a sliding cutting knife, a knife seat, an arc surface BA, a nail magazine body B, and a guide groove body. However, when using, it is necessary to rotate the pressure block several times to release the limit of the limit block, and the pressure block is far from the handle, which is inconvenient to operate, and it can only be limited and fixed after the knife is completely retracted. There is a repeated pushing area during anastomosis, which increases the labor intensity and is inconvenient to use. In view of the shortcomings of the prior art, the utility model discloses a safety locking mechanism and a stapler thereof to solve the above problems. Utility Model Content

[0011] A stapler comprises the safety locking mechanism of the stapler mentioned above.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. In the utility model, when in use, the staff holds the driving handle, puts the finger on the handle, and then squeezes the handle to move the handle upward. The upward movement of the handle will fix the rod, the movable plate and the connecting plate to make the movable plate descend. The descent of the movable plate will make the card block descend. When the card block moves out of the card slot, the cutting push button is released. At this time, it is pushed to perform the anastomosis. When the first anastomosis is completed, the handle is released. At this time, the movable plate is reset under the action of the spring. The reset of the movable plate will reset the card block, and then the cutting push button is fixed. Therefore, the cutting push button can be fixed at different positions to avoid repeated pushing. Moreover, the cutting push button can be fixed or released by one hand, which is convenient for use.

[0014] 2. In the utility model, the setting of the shock-absorbing pad plays a certain buffering role, reducing the vibration generated when the movable plate is reset. The setting of the limiting bolt and the limiting rod facilitates the limiting of the movable plate to prevent the movable plate from rotating and causing the movable plate to move when placed.
