[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example: Refer to Figure 1-Figure 4The present technical solution provides a simple meniscus resection forceps, which includes a first handle 1, the body of the first handle 1 is movably provided with a second handle 1001 through a movable axis, the lateral body of the first handle 1 is provided with a cavity, and a grip adjustment mechanism 2 is provided between the first handle 1 and the second handle 1001, the grip adjustment mechanism 2 includes a spring 203, a rotating ring 204 and a threaded shaft 205, both ends of the spring 203 are respectively provided with a first connecting block 201 and a second connecting block 202, the rotating ring 204 is located in the top cavity of the first handle 1, and the threaded shaft 205 is threadedly connected to the lateral body of the first handle 1. When in use, when it is necessary to adjust the grip resistance, the threaded shaft 205 is rotated, and the threaded shaft 205 moves the rotating ring 204 in a long axis linear direction. The spring 203 is tightened or relaxed during the movement, so that the resistance experienced by the first handle 1 and the second handle 1001 in the process of approaching each other can be adjusted, which is regarded as the adjustment of the grip strength. When the second handle 1001 is pulled When the spring 203 is compressed to its maximum, the movement of the front end head 401 will stop. Therefore, when the spring 203 is set to different angles, the maximum movable angle of the front end head 401 will also change, thereby achieving the purpose of changing the cutting angle. By arranging the anti-skid rubber particles 102, the clamping is firm and prevents slipping, thereby improving the safety and accuracy of the operation. The surface is specially treated with multiple layers of nano-antibacterial coating 101 and anti-skid rubber particles 102, which not only has anti-skid performance but also has high antibacterial effect and prevents cross infection. By arranging the sleeve rod 303, the sleeve rod 303 is plugged into the end of the first handle 1 and can be folded up when not in use for easy storage and transportation. The connecting mechanism 3 adopts a movable axis to be movably connected, which is convenient for the doctor to quickly replace different forceps heads 4 during surgery.

[0028] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer surfaces of the first handle 1 and the second handle 1001 are coated with a nano antibacterial coating 101.

[0029] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the gripping parts of the first handle 1 and the second handle 1001 are both provided with anti-slip rubber particles 102 and anti-slip patterns 103.

[0030] Reference Figure 1-Figure 4Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the first connecting block 201 is connected to the side edge of the second handle 1001, and the second connecting block 202 is connected to the outer ring of the rotating ring 204. By providing a grip adjustment mechanism 2 and embedding an adjustable grip adjustment mechanism 2, the doctor can freely adjust the clamping force according to the needs of the operation, reducing the risk of damage to surrounding tissues. The doctor can concentrate on the entire operation, closely combining the actual condition of the meniscus injury, the range of the lesion and the precise position requirements of the resection, and flexibly fine-tuning the clamping force. When facing a tiny tear at the edge of the meniscus and only needing to accurately remove damaged tissue fragments, the doctor can adjust the clamping force to a just right level of gentleness, firmly clamp the target fragments, and complete the resection cleanly and neatly.

[0031] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a connecting mechanism 3 is provided at one end of the cavity of the first handle 1, and the connecting mechanism 3 includes a straight groove plate 302, and one end of the straight groove plate 302 is movably connected to the second handle 1001 through a movable shaft.

[0032] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the movable shaft at one end of the straight groove plate 302 is movably connected to the inner wall of the cavity of the first handle 1. When the gripping resistance needs to be adjusted, the threaded shaft 205 is rotated, and the threaded shaft 205 moves the rotating ring 204 in the linear direction of the long axis. The spring 203 is tightened or relaxed during the movement, so that the resistance experienced by the first handle 1 and the second handle 1001 in the process of approaching each other can be adjusted, which is regarded as the adjustment of the gripping force.

[0033] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a sleeve rod 303 is provided at the end of the first handle 1, and a cross rod 301 is provided inside the sleeve rod 303. The end of the cross rod 301 is connected to the other end of the straight slot plate 302 through a movable shaft. When the second handle 1001 is pulled, one end of the straight slot plate 302 is pulled away, and the cross rod 301 is also pulled away, so that the bottom end of the front end head 401 rotates around its movable axis, which is regarded as the front end head 401 rotating and then completing the cutting action. When the elastic force of the spring 203 is compressed to the maximum limit, it will stop moving. Therefore, when the spring 203 is set to different angles, the maximum movable angle of the front end head 401 will also change, thereby achieving the purpose of changing the cutting angle.

[0034] Reference Figure 1-Figure 4Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that one end of the cross rod 301 is provided with a clamp head 4 through a movable shaft, the middle part of the clamp head 4 is connected to the inner wall of the sleeve rod 303 through a movable shaft, the side of the clamp head 4 is provided with a cutting blade 403, the end of the sleeve rod 303 is provided with a front end head 401, the top of the front end head 401 is provided with a clamping surface 402, and one end of both sides of the sleeve rod 303 is provided with a depth mark 404.

[0035] Specifically, the working process or working principle of this simple meniscus resection forceps is as follows: when in use, when the gripping resistance needs to be adjusted, the threaded shaft 205 is rotated, and the threaded shaft 205 moves the rotating ring 204 in a linear direction of the long axis. The spring 203 is tightened or relaxed during the movement, so that the resistance experienced by the first handle 1 and the second handle 1001 in the process of approaching each other can be adjusted, which is regarded as the adjustment of the gripping force. When the second handle 1001 is pulled, one end of the straight groove plate 302 is pulled away, and the cross rod 301 is also pulled away, so that the bottom end of the front end head 401 rotates around its movable axis, which is regarded as the front end head 401 rotating and then completing the resection action. When the elastic force of the spring 203 is compressed to the maximum limit, it will stop moving. Therefore, when the spring 203 is set to different angles, the maximum movable angle of the front end head 401 will also change, thereby achieving the purpose of changing the resection angle.

[0036] It should be noted that the spring 203 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
