Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinal basket clamp technology, specifically to a pinless spinal basket clamp. Background Technology
[0002] Spinal basket forceps are used in conjunction with spinal endoscopes to perform examinations and surgical procedures within the spine. They may have functions such as gripping and moving tissues, helping doctors to accurately handle intervertebral disc fragments, bone fragments, or other related tissues during surgery, reducing damage to surrounding tissues, improving surgical efficiency, and shortening patient recovery time. Current spinal basket forceps generally use the rear handle as the movable handle, with two pins at the front end for auxiliary cutting operations, which results in instability and weak cutting force. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a pinless spinal basket clamp that is stable in use and has strong shearing force, in view of the shortcomings mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pinless spinal basket clamp, comprising a clamp body, the clamp body including a rear fixed handle and a front movable handle, the movable handle being rotatably connected to the fixed handle, a connecting shaft being connected to the front end of the fixed handle, an outer tube being connected to the front end of the connecting shaft, a fixed head being fixed at the front end of the outer tube, a movable head being rotatably provided without pins on the inner side of the fixed head, a push rod being connected to the end of the movable handle and passing through the connecting shaft and the outer tube, and a push head being rotatably provided without pins at the end of the push rod.
[0005] Furthermore, a water injection pipe communicating with the inner part of the outer pipe is connected to one side of the connecting shaft to facilitate auxiliary water injection.
[0006] Furthermore, the fixed head is provided with a first concave-convex circular structure on its inner side, the moving head is provided with a second concave-convex circular structure that moves in conjunction with the first concave-convex circular structure on its outer side, the moving head is provided with a third concave-convex circular structure on its inner side, and the push head is provided with a fourth concave-convex circular structure that moves in conjunction with the third concave-convex circular structure on its outer side, which facilitates the pinless operation of the end moving head.
[0007] The advantages of this pinless spinal basket clamp compared to the prior art are: operability and the use of the front handle as the movable handle, which effectively improves the stability of the clamp during use.
[0008] The pliers feature a pinless, convex-concave-circular joint mechanism at the head push rod position, providing greater shearing force compared to traditional pliers that use two pins. Attached Figure Description

Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] Combined with appendix Figure 1-7 A pinless spinal basket clamp includes a clamp body 1, wherein the clamp body 1 includes a rear fixed handle 2 and a front movable handle 3, wherein the movable handle 3 is rotatably connected to the fixed handle 2, as shown below. Figure 3 As shown, the operability of the entire basket clamp can be improved by setting the front end as a movable handle 3. The front end of the fixed handle 2 is connected to a connecting shaft 4. One side of the connecting shaft 4 is connected to a water injection pipe 9 that communicates with the inner part of the outer tube 5. The front end of the connecting shaft 4 is connected to the outer tube 5. The front end of the outer tube 5 is fixed head 6. The inner side of the fixed head 6 is provided with a movable head 7 that rotates without a pin. The end of the movable handle 3 is connected to a push rod 8 that passes through the connecting shaft 4 and the outer tube 5. The end of the push rod 8 is connected to a push head 10 that rotates without a pin with the movable head 7. That is, by pushing and pulling the push rod 8 with the movable handle 3, the movable head 7 can be adjusted in conjunction with the push head 10 that rotates without a pin.
[0019] The fixed head 6 has a first concave-convex circular structure 11 connected to its inner side, the movable head 7 has a second concave-convex circular structure 12 connected to its outer side to cooperate with the first concave-convex circular structure 11, the movable head 7 has a third concave-convex circular structure 13 connected to its inner side, and the push head 10 has a fourth concave-convex circular structure 14 connected to its outer side to cooperate with the third concave-convex circular structure 13. The concave-convex circular structures are as follows: Figure 4-7 As shown, the semi-circular or semi-elliptical protrusion, in conjunction with the groove, allows the pusher head 10 to push the moving head 7, enabling movable shearing operations without pins, thereby greatly increasing the shearing force. The swinging handle controls the opening and closing of the pliers head, with the head opening angle being approximately 45°.
[0020] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
