[0006] The effect achieved by the above components is: laparoscopic total extraperitoneal inguinal hernia repair has gradually become the mainstream surgical method for inguinal hernia due to its advantages such as small trauma, short operation time, and no need to enter the abdominal cavity. Therefore, laparoscopic hernia special scissors are usually used for auxiliary operation. During the long-term use of the scissors, in order to prevent the sleeve rod on the surface of the scissors core from loosening and falling off, in order to effectively fix and limit the sleeve rod, the rotating plates on the surfaces of both sides of the rotating connecting tube are first rotated, and then the rotating shaft on the surface of the rotating plate is rotated, so that the extrusion plate rotating at one end of the rotating shaft and the fixed frame on the surface of the sleeve rod are squeezed, so that the entire sleeve rod and the connecting tube are better fixed to avoid the sleeve rod from falling off after long-term use.

[0007] Preferably, the inner walls of the fixing frame are sleeved with coil springs, and two ends of the coil springs are fixedly connected to the fixing frame and the rotating plate respectively.

At this time, the protective cover made of silicone material is connected to the inner wall of the left curved handle, and then the insertion rod on the surface of the protective cover is used to connect and limit the insertion of the tube on the side wall of the left curved handle, so as to effectively and conveniently protect the entire scissors.

[0015] Preferably, a plurality of anti-slip grooves are formed on the inner wall surface of the protective sleeve, and the plurality of anti-slip grooves are evenly distributed on the inner wall surface of the protective sleeve.

[0016] The effect achieved by the above components is that the friction can be effectively increased through the anti-slip groove, so that the left-bend handle can be better used.

[0017] Preferably, the length of the sleeve rod is matched with the size of the shear core, and the sleeve rod is an insulating coated rod.

[0018] The effect achieved by the above components is: the entire scissors head can be deeply covered by the sleeve rod made of insulating coating material, so as to avoid too much metal part exposed at the cutting tip of the scissors head. During the use of electric cutting, too much metal leakage may lead to contact with blood vessels, nerves, and muscles, causing secondary damage. In addition, the scissors head opens too much and is not suitable for use in the smaller surgical space of TEP, which can easily cause the chopstick effect.

The laparoscopic complete extraperitoneal inguinal hernia repair has gradually become the mainstream surgical method for inguinal hernia due to its advantages of small trauma, short operation time, and no need to enter the abdominal cavity. Therefore, the special scissors for laparoscopic hernia are usually used for auxiliary operation. In the process of long-term use of the scissors, in order to prevent the sleeve rod on the surface of the scissors core from loosening and falling off, in order to effectively fix and limit the sleeve rod, the rotating plates on the surfaces of both sides of the rotating connecting tube are first rotated, and then the rotating shaft on the surface of the rotating plate is rotated, so that the extrusion plate rotating at one end of the rotating shaft and the fixed frame on the surface of the sleeve rod are squeezed, so that the entire sleeve rod and the connecting tube are fixed. The tubes are better fixed to avoid the sheath rod from falling off after long-term use. The sheath rod made of insulating coating material can cover the entire scissors head more deeply to avoid too much metal part exposed at the cutting tip of the scissors head.
