A link structure for skull fixation

Abstract

The present application discloses a linking structure for skull fixation, comprising a linking piece and a supporting member, wherein the two ends of the linking piece are respectively fixed on a patch and a skull, a supporting portion is arranged in the middle of the linking piece, and the supporting member is inserted into the supporting portion. The structure and the method of use thereof are very simple, but the skull and the patch can be securely fixed, and the disassembly is convenient, so that the linking piece is convenient for use during surgery.

Description

Technical Field

[0001] The present application relates to a linking structure for skull fixation, belonging to the field of skull fixation structures. Background Art

[0002] Cranioplasty is a common neurosurgery procedure that solves problems such as abnormal cerebral blood supply, insufficient or obstructed cerebrospinal fluid circulation, and brain compression caused by skull defects.

[0003] In current cranial repair surgeries, the skull and the repair piece cannot be stably connected, and the connecting pieces used for connection have a complex structure, which is not conducive to the smooth progress of the surgery. Utility Model Content

[0004] According to one aspect of the present application, a linking structure for skull fixation is provided, comprising a linking piece and a supporting member, wherein two ends of the linking piece are respectively fixed to a patch piece and a skull;

[0005] A supporting portion is provided in the middle of the linking piece, and the supporting member is inserted into the supporting portion.

[0006] Optionally, the linking piece is respectively fixed to the patch piece and the skull thread.

[0007] Optionally, the link plates are symmetrically arranged.

[0008] Optionally, the supporting portion is a groove opened in the middle of the linking piece.

[0009] Directions:

[0010] First, the two ends of the linking piece are fixed to the patch and the skull respectively by screws or other fixing components;

[0011] Then, the support member is inserted into the support portion, and the linking piece expands to tighten the skull and the patch, thereby achieving fixation of the skull and the patch.

[0012] The beneficial effects of this application include:

[0013] The present application provides a link structure for skull fixation, which has a very simple structure and usage, but can securely fix the skull and the patch, and is easy to disassemble and use during surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

[0020] According to one implementation of the present application, Figure 1 As shown, a link structure for skull fixation is provided, comprising a linking piece 1 and a supporting member 2, wherein two ends of the linking piece 1 are respectively fixed on a patch piece 4 and a skull 5;

[0021] A support portion 3 is provided in the middle of the linking sheet 1 , and the support member 2 is inserted into the support portion 3 .

[0022] The linking piece 1 is respectively fixed to the patch piece 4 and the skull 5 by threads.

[0023] The linking plates 1 are symmetrically arranged.

[0024] The support portion 3 is a groove formed in the middle of the linking piece 1 .

[0025] like Figures 2-3 As shown, the usage and principle of the link structure are as follows:

[0026] First, the two ends of the linking piece 1 are fixed to the patch piece 4 and the skull 5 respectively by screws 6; at this time, the supporting part 3 maintains the initial state, and its groove width is A1;

[0027] Then, the support member 2 is inserted into the support portion 3. At this time, the support portion 3 is opened by the support member 2, and its groove width is A2. At the same time, the upper and lower edges of the support portion 3 are subjected to force F (the force direction is as follows Figure 3 As shown), the force transmission linking plate 1 expands and tightens the skull 5 and the patch 4, thereby fixing the skull 5 and the patch 4.

[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.
