Description

Technical Field

[0001] The utility model relates to the technical field of cone plate rongeurs, in particular to a novel rotary cone plate rongeurer. Background Art

[0002] A laminar rongeur is a surgical instrument used to remove the lamina and other bony tissue during spinal surgery. The design of this instrument allows the surgeon to precisely remove bone to gain access to the spinal canal, relieve pressure on neural structures, or perform other necessary surgical procedures.

[0003] Currently, the angles of the pliers heads of lamina rongeurs on the market are mostly divided into 90°, 110° and 130°, which can meet most surgical operation needs. However, once the required operation depth of the spinal canal is too deep or the angle is inappropriate, pliers heads with other angles are required to operate and reduce the difficulty of operating the lamina rongeurs. In addition, the disassembly, assembly and rotation adjustability of the lamina rongeurs are poor, which affects the use effect of the lamina rongeurs. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-5 In the present utility model, a new type of rotary cone plate bone rongeur comprises a handle 1, a first operating rod 2 is installed on the handle 1, a rod core 3 slidably connected to the inner side of the first operating rod 2 is inserted into the inner side of the first operating rod 2, one end of the rod core 3 extends to the interior of the handle 1, wherein a buffer spring 4 is fixedly installed between the end of the rod core 3 located inside the handle 1 and the first operating rod 2, a lower bone clamp 5 is integrally formed at the end of the first operating rod 2 away from the handle 1, an upper bone clamp 6 is integrally formed at the end of the rod core 3 away from the handle 1, and the upper bone clamp 6 is slidably mounted on the lower bone clamp 5, the angle between the lower bone clamp 5 and the inner side of the first operating rod 2 is an acute angle, and the upper bone clamp 6 matches the lower bone clamp 5.

[0029] In the present invention, the first operating rod 2 is installed on the handle 1, and the handle 1 is operated to push the rod core 3 to move, which can drive the upper bone clamp 6 and the lower bone clamp 5 on the rod core 3 to approach and fit together. During the process, the elastic force of the buffer spring 4 plays a buffering role. At the same time, after the operation is completed, it is convenient to pull back the rod core 3 to drive the upper bone clamp 6 to reset, providing a setting method in which the inner angle between the lower bone clamp 5 and the first operating rod 2 is an acute angle, which can adapt to the operation of deeper spinal structures, facilitate the satisfaction of the bone clamping work requirements in complex situations, and reduce the difficulty of surgical operation.

[0030] See also Figure 1-3 , wherein: the grip 1 includes a handle 11 and a second operating rod 12 hinged to the handle 11, the top of the second operating rod 12 extends to the inside of the handle 11 and contacts the rod core 3, and a clamping part 13 is installed on the handle 11.

[0031] In the present invention, by gripping the handle 11 and the second operating rod 12, the second operating rod 12 is driven to approach the handle 11, the top end of the second operating rod 12 moves, pushing the rod core 3 to move, and the buffer spring 4 completes the reset when the second operating rod 12 is released.

[0032] See also Figure 1-3, wherein: the clamping member 13 includes a rotating nut 131 threadedly connected to the handle 11, the end of the handle 11 is slidably connected to a clamping ring 132, the clamping ring 132 consists of two semicircular rings 1321, one side of the two semicircular rings 1321 extends to the inner side of the rotating nut 131, and the operating rod 2 is located between the two semicircular rings 1321.

[0033] In the present invention, by rotating the rotating nut 131 and utilizing the threaded connection between the rotating nut 131 and the handle 11, the position of the rotating nut 131 on the handle 11 is adjusted. When installing and fixing, the rotating nut 131 squeezes the two semicircular rings 1321 to form a complete clamping ring 132, thereby clamping and fixing the inner operating rod 2. When it is necessary to disassemble and replace other styles of pliers, the rotating nut 131 can lose the restriction on the clamping ring 132, and the two semicircular rings 1321 can be separated, loosening the fixing effect on the operating rod 2, so that the operating rod 2 can be rotated to change the direction of the pliers, or the operating rod 2 can be directly replaced.
