Anti-relaxation skull locking groove

Abstract

The anti-loosening skull locking groove comprises a repairing piece and a curved bar movably connected with the repairing piece, an inward clamping groove is formed in the lower portion of the repairing piece, a clamping part matched with the clamping groove is arranged on the upper portion of the curved bar, and an inserting part connected with a skull in an inserted mode is arranged at the bottom end of the curved bar. The cranked lever which can be inserted into the skull and clamped with the repairing piece is adopted to form a stable skull locking groove, and the situation that the repairing effect is affected due to looseness of the skull locking device can be effectively prevented.

Description

Technical Field

[0001] The present application relates to an anti-loosening skull lock slot, belonging to the field of skull lock slot devices. Background Art

[0002] For any reason, craniotomy is required, and skull repair is usually divided into embedding repair and covering repair. PEEK is a special polymer organic material that can withstand up to 3,000 cycles of high-pressure sterilization at 134°C. It can show high mechanical strength, good stress resistance and hydrolytic stability under conditions such as hot water, steam, solvents and chemical reagents. This feature makes it suitable for surgical operations with high sterilization requirements and repeated use. The existing skull locking groove is prone to loosening during use, affecting the repair effect. Utility Model Content

[0003] According to one aspect of the present application, there is provided an anti-loosening skull lock slot, comprising a patch and a curved rod movably connected thereto;

[0004] The lower part of the patch is provided with an inwardly facing slot;

[0005] The upper part of the curved rod is provided with a clamping part adapted to the clamping slot, and the bottom end of the curved rod is provided with an inserting part inserted into the skull.

[0006] Optionally, the patch and the curved rod are both bilaterally symmetrical structures.

[0007] Optionally, the patch is configured as an M-shaped inward-facing structure.

[0008] Optionally, the curved rod is configured as a V-shaped ear-hanging structure.

[0009] Directions:

[0010] Drill a V-shaped groove inward on the skull, drill a plug-in groove inward at the bottom of the V-shaped groove, insert the plug-in part at the bottom of the curved rod into the plug-in groove, and squeeze the upper part of the curved rod to put it into the card slot at the bottom of the patch;

[0011] When the curved rod is released, it rebounds automatically, and the upper end ear is inserted into the slot of the patch to achieve fixed connection between the skull and the patch.

[0012] The beneficial effects of this application include:

[0013] The present application provides an anti-loosening skull locking groove, which adopts a curved rod that can be inserted into the skull and interlocked with the repair piece to form a stable skull locking groove, which can effectively prevent the skull locking device from loosening during surgery and affecting the repair effect.

[0018] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

[0019] According to one embodiment of the present application, there is provided an anti-relaxation skull 3 locking slot, comprising a patch 1 and a curved rod 2 movably connected thereto;

[0020] The lower part of the patch 1 is provided with an inwardly facing slot 4;

[0021] The upper part of the curved rod 2 is provided with a clamping portion 5 adapted to the clamping slot 4 , and the bottom end of the curved rod 2 is provided with an inserting portion 6 inserted into the skull 3 .

[0022] The patch 1 and the curved rod 2 are both bilaterally symmetrical structures.

[0023] The patch 1 is configured as an M-shaped inward buckled structure.

[0024] The curved rod 2 is configured as a V-shaped ear-hanging structure.

[0025] Directions:

[0026] Drill a V-shaped groove inward on the skull 3, drill a plug-in groove inward at the bottom of the V-shaped groove, insert the plug-in portion 6 at the bottom of the curved rod 2 into the plug-in groove, and squeeze the upper part of the curved rod 2 to put it into the card slot 4 at the lower part of the patch 1;

[0027] When the bent rod 2 is released, it rebounds automatically, and the upper end ear is inserted into the slot 4 of the patch 1, so that the skull 3 and the patch 1 are fixedly connected.

[0028] The above description is only a partial embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the above disclosed technical content to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
