[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 4 In an embodiment of the utility model, a special instrument for tumor resection includes a handle 1 and a cutting knife 2. Both sides of the rear end of the handle 1 are provided with multiple groups of anti-slip grooves 14, which can improve the stability of the medical staff holding the instrument. A connecting piece is slidably installed inside the handle 1. Both sides of the handle 1 are provided with connecting grooves 3 for the connecting piece to slide. A mounting rod 4 that can slide inside the handle 1 is installed at the front end of the connecting piece. The cutting knife 2 is detachably installed at the front end of the mounting rod 4. The connecting piece extends to the surface of both sides of the handle 1 and is slidably installed up and down with a limit frame. Two groups of clamping rods 5 for positioning the limit frame are installed on both sides of the handle 1. An elastic support piece connected to the limit frame is slidably installed on the top of the handle 1.

[0023] After the special tool for tumor resection has been used and disinfected, the operator can pull up the limit frame, and after pulling the limit frame to the top of the front end clamping rod 5, the limit frame can slide back and forth on the surface of the handle 1, and the limit frame drives the connecting piece to slide back and forth inside the handle 1 and the connecting groove 3, and the connecting piece drives the mounting rod 4 and the cutting knife 2 to slide. After the cutting knife 2 is retracted into the inside of the handle 1, the connecting piece slides to the rear end of the connecting groove 3. When the limit frame is pulled up, it can drive the elastic support member to extend and retract. When the external force on the limit frame is removed, the limit frame can be clamped to the rear side of the clamping rod 5 at the rear end through the resetting of the elastic support member, so that the cutting knife 2 can be fixed inside the handle 1.

[0024] In one embodiment, specifically, the connecting member includes a sliding rod 6 slidably installed inside the connecting groove 3, and the surface of the sliding rod 6 located inside the handle 1 is connected with a connecting block 7, and the connecting block 7 is fixedly connected to the rear end of the mounting rod 4. When the sliding rod 6 is pulled by the limiting frame, the connecting block 7 can be driven to move, and the connecting block 7 can drive the mounting rod 4 to move.

[0025] Among them, the limit frame includes a U-shaped plate 8 that is buckled on the outside of the handle 1, and both sides of the U-shaped plate 8 are provided with sliding grooves 9 for the sliding rod 6 to slide. When the sliding rod 6 is located at one end inside the connecting groove 3, the side of the U-shaped plate 8 can abut against the side of one group of clamping rods 5. The U-shaped plate 8 pulls the sliding rod 6 to move back and forth inside the connecting groove 3 through the sliding grooves 9 on both sides. The U-shaped plate 8 moves up and down and is clamped to the side of the clamping rod 5, which can realize the fixation of the connecting piece and the cutting knife 2.

[0026] On the basis of the above embodiment, specifically, the elastic support member includes a skateboard 10 on the top of the sliding installation handle 1, and the U-shaped plate 8 is slidably installed inside the skateboard 10. A spring 11 is connected between the top of the skateboard 10 and the top plate of the U-shaped plate 8. The up and down movement of the U-shaped plate 8 can drive the spring 11 to retract and retract, and the front and back pulling of the U-shaped plate 8 can drive the skateboard 10 to move. The spring 11 provides elastic support for the up and down movement of the U-shaped plate 8, and the rebound of the spring 11 can facilitate the U-shaped plate 8 to be snapped to the side of one set of the clamping rods 5.

[0027] Furthermore, a limiting rod 12 penetrating the spring 11 and the top plate of the U-shaped plate 8 is fixedly installed on the top of the skateboard 10. The U-shaped plate 8 can slide up and down on the surface of the limiting rod 12. The limiting rod 12 can improve the stability of the up and down movement of the U-shaped plate 8 and prevent the lateral deformation of the spring 11. Two groups of springs 11 and limiting rods 12 are arranged between the skateboard 10 and the U-shaped plate 8, which can provide stable elastic support for the U-shaped plate 8. The top ends of the two groups of limiting rods 12 are connected to the same baffle plate 13, which can limit the space for the U-shaped plate 8 to move upward and improve the overall stability of the component.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
