Description

Technical Field

[0001] The invention relates to the technical field of spinal basket forceps, in particular to a pinless spinal basket forceps. Background Art

[0002] Spinal basket forceps are used in conjunction with a spinal endoscope to perform inspections and surgical operations within the spine. They may have functions such as clamping and moving tissues, helping doctors to accurately handle intervertebral disc fragments, bone blocks or other related tissues during surgery, reduce damage to surrounding tissues during surgery, improve surgical efficiency, and shorten patient recovery time. Spinal basket forceps in the prior art generally have a rear handle as a movable handle and two pins at the front end for auxiliary shearing operations, which results in unstable use and weak shearing force. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a pinless spinal basket forceps which is stable in use and has strong shearing force in view of the deficiencies in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a pinless spinal basket forceps, including a basket forceps body, the basket forceps body including a rear end fixed handle and a front end movable handle, the movable handle is rotatably connected to the fixed handle, the front end of the fixed handle is connected to a connecting shaft, the front end of the connecting shaft is connected to an outer tube, the front end of the outer tube is fixed with a head, the inner side of the fixed head is rotatably provided with a movable head without a pin, the end of the movable handle is connected with a push rod passing through the connecting shaft and the outer tube, and the end of the push rod is connected with a push head rotatably provided with the movable head without a pin.

[0005] Furthermore, a water injection pipe connected to the outer tube is provided on one side of the connecting shaft to facilitate auxiliary water injection.

[0006] Furthermore, the fixed head is connected on the inner side with a first concave-convex circular structure, the movable head is connected on the outer side with a second concave-convex circular structure that cooperates with the first concave-convex circular structure, the movable head is connected on the inner side with a third concave-convex circular structure, and the push head is connected on the outer side with a fourth concave-convex circular structure that cooperates with the third concave-convex circular structure, so as to facilitate the pin-free movable operation of the end movable head.

[0007] The advantages of the pinless spinal basket forceps of the present invention compared with the prior art are: operability, using the front handle as a movable handle, effectively improving the stability of the forceps in use;

[0008] Usability: The head push rod position uses a pinless concave-convex circle matching structure, which has greater shear force than traditional pliers using two pins. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] Combined with Figure 1-7 A pinless spinal basket clamp comprises a basket clamp body 1, wherein the basket clamp body 1 comprises a rear fixed handle 2 and a front movable handle 3, wherein the movable handle 3 is rotatably connected to the fixed handle 2. Figure 3 As shown, the front end is provided with a movable handle 3, so that the operability of the entire basket clamp can be improved. The front end of the fixed handle 2 is connected with a connecting shaft 4, and one side of the connecting shaft 4 is connected with a water injection pipe 9 connected with the outer tube 5. The front end of the connecting shaft 4 is connected with the outer tube 5, and the front end of the outer tube 5 is fixed with a head 6, and the inner side of the fixed head 6 is provided with a movable head 7 that is rotatable without a pin. The end of the movable handle 3 is connected with a push rod 8 that runs through the connecting shaft 4 and the outer tube 5, and the end of the push rod 8 is connected with a push head 10 that is rotatable with the movable head 7 without a pin, that is, the push rod 8 is pushed and pulled by the movable handle 3, and the movable head 7 can be adjusted in cooperation with the push head 10 that is rotatable without a pin.

[0019] The fixed head 6 is connected to a first concave-convex circular structure 11 on the inner side, the movable head 7 is connected to a second concave-convex circular structure 12 on the outer side to cooperate with the first concave-convex circular structure 11, the movable head 7 is connected to a third concave-convex circular structure 13 on the inner side, and the push head 10 is connected to a fourth concave-convex circular structure 14 on the outer side to cooperate with the third concave-convex circular structure 13. Figure 4-7 As shown, it is a semicircular or semi-elliptical protrusion, which cooperates with the displayed groove. By pushing the movable head 7 through the push head 10, active shearing operations can be performed without pins, thereby greatly improving the shearing force, swinging the movable handle, and controlling the opening and closing of the pliers head. The opening angle of the head is about 45°.

[0020] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
