Abstract

The utility model discloses a cervical vertebrae fixing device, the fixing device comprises a fixing guard board. A plurality of locking holes are arranged on the fixing guard board. The locking holes are separately provided with the supporting column. The supporting column is in spiral shape which is embedded in the cervical for fixing. The utility model is characterized in that a clearance between the guard board and the cervical is reserved to form gap when the fixing guard board is arranged on the cervical to be fixed and the supporting column on the fixing guard board is screw fixed on the cervical. So the regenerated bone of the cervical vertebrae is generated from the gap and wraps the supporting column, which makes the supporting column and the cervical vertebrae fastened tightly.

Description

The cervical vertebra fixture

Technical field

This utility model relates to a kind of cervical vertebra fixture, refers to the fixture that a kind of fixedly neck bone is used especially, even make the multiple lock of fixture establish adjustment, it still can be fixed together with cervical vertegra very closely.

Background technology

The cervical vertebra fixture 10a that tradition is used, as shown in Figure 1, it has a fixing backplate 1a, fixedly backplate 1a pastes on neck bone 20a, in addition, is provided with several support cylinders 2a, this support cylinder 2a one end has spire 22a, fixes to be implanted in the neck bone 20a.Now when utilizing fixture 10a fixedly during neck bone 20a, its fixedly backplate 1a closely paste to protect on neck bone 20a, support cylinder 2a then locks from fixing backplate 1a and penetrates in neck bone 20a, thus can utilize this fixedly backplate 1a and support cylinder 2a to fix neck bone 20a.

Desire to adjust as above-mentioned support cylinder 2a and must lock again when establishing, its originally on neck bone 20a formed screw can establish because of support cylinder 2a lock once more the screw aperture is increased, make the spire 22a of support cylinder 2a with between neck bone 20a, can't be screwed on closely again, and fixedly backplate 1a abuts on the neck bone 20a, also can't make the regeneration bone coat interlock and live in support cylinder 2a, and then support cylinder 2a and neck are pushed away come loose easily between bone 20a and can't closely fix, lose the original fixed function of its fixture 10a so, on the contrary.

Summary of the invention

Main purpose of the present utility model is to provide a kind of cervical vertebra fixture, still can be fixed together with neck bone very closely even it makes the multiple lock of this fixture establish adjustment.

For achieving the above object, this utility model provides a kind of cervical vertebra fixture, and it comprises: a fixing backplate is provided with at least one lock in fixing backplate and establishes the hole; At least one support cylinder, it is to establish Kong Zhongsuo from the fixing lock of backplate to wear and be implanted in the neck bone, fixes neck bone by support cylinder; And this support cylinder lock wears when being implanted in the neck bone, fixedly can reserve a spacing between backplate and neck bone and be formed with the space, and this space can make the regenerated bone of neck bone bear from here, and support cylinder is lived in the coating interlock.

That is to say, of the present utility model one is characterised in that this fixture includes a fixing backplate, be provided with several locks in fixing backplate and establish the hole, and establish in the hole respectively at these locks that lock is provided with support cylinder, this support cylinder is portion in the shape of a spiral, fix to be implanted in the neck bone, backplate is sticked on the fixed neck bone of desire and work as fixedly, and spiral shell is established support cylinder in neck pushes away bone the time on fixing backplate, fixedly can reserve a spacing between backplate and neck bone and be formed with the space, so, can make the regenerated bone of neck bone from the space, bear and coat interlock and live support cylinder, make still can be firm between support cylinder and neck bone be fixed together.

Another feature of the present utility model is that the top of this support cylinder can be provided with the runner that is connected with neck bone toward in, makes in this runner and pours into bone cement, more closely firmly is fixed together to make between support cylinder and neck bone by this bone cement.

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however described accompanying drawing only provides reference and explanation, is not to be used for this utility model is limited.

The specific embodiment

This utility model is a kind of cervical vertebra fixture, please refer to Fig. 2 and shown in Figure 3, and this fixture 10 includes a fixing backplate 1, and fixedly backplate 1 is to have radian, with fit neck vertebra 20, is provided with several locks in fixing backplate 1 and establishes hole 11.In addition, lock is provided with support cylinder 2 respectively in these locks are established hole 11, this support cylinder 2 has a head 21, the top 211 of head 21 can be for the hand tools butt joint, head 21 other ends then extend and are provided with spire 22, fix to be implanted in the neck bone 20, the external diameter of this head 21 is greater than spire 22, head 21 can't be locked be located on the neck bone 20.Fixedly can be provided with at least one lock on the backplate and establish hole and at least one support cylinder.

Please refer to shown in Figure 4, in this utility model, when fixing backplate 1 is sticked on the fixed neck bone 20 of desire, and spiral shell is established support cylinder 2 to neck bone 20 time on fixing backplate 1, fixedly

backplate

1 and 20 of neck bones can be reserved a spacing and be formed with space 3, and the regeneration bone 201 that this space 3 can make neck push away bone 20 bears from here.

So, when using this fixture 10 on neck bone 20, these support cylinders 2 are when locking in neck bone 20, because of head 21 external diameters of support cylinder 2 greater than its spire 22, once support cylinder 2 is locked behind neck bone 20, the head 21 of its support cylinder 2 is to be resisted against on the outer surface of neck bone 20, makes fixedly

backplate

1 and 20 formation of neck bone space 3, so the regeneration bone 201 of neck bone 20 promptly can bear and coat the head 21 that support cylinder 2 is lived in interlock from space 3.

Please refer to shown in Figure 5, its another embodiment sketch map of the present utility model, wherein the top 211 of this support cylinder 2 can be provided with an axial runner 23 toward in, in addition, is horizontally set with the by-path 24 that several are connected with neck bone 20 on this runner 23.Pour into bone cement in this runner 23, bone cement flows in each by-path 24 and with neck bone 20 again and is connected, and so, can support

cylinder

2 and 20 of neck bones more closely firmly is fixed together by this bone cement.

As above-mentioned structure, because, the regeneration bone 201 of this neck bone 20 can interlock envelope support cylinder 2, therefore, when support cylinder 2 must adjust again lock when establishing because of demand, even 20 of support cylinder 2 and neck bones can't screw togather closely, also can be by this coating of bone 201 of regenerating, and make being fixed together that support

cylinder

2 and 20 of neck bones still can be firm.

In sum, cervical vertebra fixture of the present utility model can reach described function by the above-mentioned structure that discloses really.And do not see the also unexposed use of publication before this utility model application.

Above-mentioned accompanying drawing that discloses and explanation only are embodiment of the present utility model, and be non-for limiting embodiment of the present utility model; Every personage who is familiar with this technology, it is according to feature category of the present utility model, and other equivalence of being done changes or modifies, and all should be encompassed in the claim of following the application's case.
