Abstract
The utility model belongs to the technical field of medical instruments and provides a spine fixing titanium plate which solves the technical problems existing during multiple canalis vertebralis fixation performed by the currently-used spine fixing device. The fixing titanium plate is composed of a plurality of single-section canalis vertebralis fixing plates which are arc titanium plates with wings at two sides, wherein screw holes are formed in the two side wings. The fixing titanium plate is characterized in that the length of each of the two side wings of the single-section canalis vertebralis fixing plates is larger than that of each of the arc titanium plates, and the single-section canalis vertebralis fixing plates are hinged in an involution mode through side wing end portions. The spine fixing titanium plate is reasonable in structure, good in spine protection effect, and capable of facilitating rapid recovery after a spinal operation.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically refers to fixedly titanium plate of a kind of spinal column.
Background technology
Spinal trauma or spinal canal stenosis need cone joint to be fixed after performing the operation, and take spinal canal stenosis operation as example, and mostly it is the operation of row way of escape laminectomy for decompression, vertebral plate disappearance after operation, dural sac exposes, and therefore the cicatrix that there will be rear soft tissue to form need to adopt titanium plate to be fixed.As ZL201020595462.X, a kind of spinal column rearward protect titanium plate is disclosed in this patent document, this titanium plate mid portion is rearwardly projecting arcuation platy structure, the both sides band wing with screw hole, is fixed on this plate in respective vertebrae by screw on two flanks.For another example ZL200720088096.7, this patent discloses a kind of spinal plate fixture device, and this holder consists of titanium plate, pedicle nail and nut, and titanium plate middle part is arch.Use above-mentioned fixture to find in practice, when needs are to single-unit canalis spinalis fixedly time, its effect is better, and when 2 joints or the above canalis spinalis of two joints are fixed, and the one, adopt the measure that titanium plate is lengthened, it two is that single-unit canalis spinalis is fixed respectively.And the measure that adopts titanium plate to lengthen can produce stiff sense, spinal column shock-absorbing capacity variation fixing rear patient.And adopt single-unit canalis spinalis fixing respectively, and there is the left and right changing of the relative positions in the meeting between canalis spinalis and canalis spinalis, and this phenomenon especially shows particularly outstanding in the case of some many canalis spinalis comminuted fracture for the treatment of.
Summary of the invention
For the spinal fixation system that overcomes current use is carrying out many canalis spinalis existing technical problem fixedly time, this utility model provides fixedly titanium plate of a kind of spinal column.
The technical solution adopted in the utility model is: spinal column is titanium plate fixedly, this fixedly titanium plate by some single-unit canalis spinalis fixing heads, formed, described single-unit canalis spinalis fixing head is the arc titanium plate of the both sides band wing, on two flanks, be provided with screw hole, it is characterized in that: the length of described single-unit canalis spinalis fixing head two flanks surpasses the length of arc titanium plate, involutory hinged by flank end between single-unit canalis spinalis fixing head.
The piece number of described single-unit canalis spinalis fixing head is 2-4 piece.
This spinal column fixedly titanium plate adopts after said structure, when needs are fixed more piece canalis spinalis, can corresponding single-unit canalis spinalis fixing head be connected according to fixing canalis spinalis quantity, every joint canalis spinalis is in fixing by single-unit canalis spinalis fixing head, joint with joint canalis spinalis between while also realized and being connected, prevent from because left and right occurs in activity, misplacing between canalis spinalis and canalis spinalis, the bending between canalis spinalis and canalis spinalis is unaffected.Fixedly titanium plate structure is reasonable for this spinal column, good to the protection effect of spinal column, is conducive to the Quick-return after spinal operation.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1, single-unit canalis spinalis fixing head, 2, arc titanium plate, 3, flank, 4, screw hole, 5, hinged cover, 6, jointed shaft.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described further.
As shown in drawings, spinal column is titanium plate fixedly, this fixedly titanium plate by two single-unit canalis spinalis fixing heads 1, be formed by connecting, during actual fabrication, can according to fixing canalis spinalis quantity, determine the quantity of single-unit canalis spinalis fixing head 1, generally with 2-4 piece, be advisable.
As shown in drawings, the structure of single-unit canalis spinalis fixing head 1 comprises an arc titanium plate 2, the both side ends of arc titanium plate 2 is horizontally outward extended and is become flank 3, but the length of flank 3 will surpass the length of arc titanium plate 2, so that two joint single-unit canalis spinalis fixing heads are not subject to the restriction of arc titanium plate 2 when bending.On 1 liang of flank 3 of single-unit canalis spinalis fixing head, be respectively equipped with screw hole 4 so that fixing head and canalis spinalis bone are fixed.
As shown in drawings, the hinged cover 5 that the butt ends of two joint single-unit canalis spinalis fixing head flanks are respectively equipped with hinged cover 5, the two joint single-unit canalis spinalis fixing head flank ends of rolling is mutually pegged graft and is realized hinged by jointed shaft 6.
The continuous canalis spinalis that two joints of take need to be fixed is example, by the spinal column shown in this embodiment fixedly the single-unit canalis spinalis fixing head 1 of titanium plate be fixed by screws in respectively canalis spinalis rear, two joint canalis spinalis can be realized normal bending, realize the pooling feature of spinal column, simultaneously also can avoid the left and right changing of the relative positions between canalis spinalis and cause after spine recovering crooked.
Claims (2)
1. the fixing titanium plate of spinal column, this fixedly titanium plate by some single-unit canalis spinalis fixing heads, formed, described single-unit canalis spinalis fixing head is the arc titanium plate of the both sides band wing, on two flanks, be provided with screw hole, it is characterized in that: the length of described single-unit canalis spinalis fixing head two flanks surpasses the length of arc titanium plate, involutory hinged by flank end between single-unit canalis spinalis fixing head.
2. the fixing titanium plate of spinal column according to claim 1, is characterized in that: the piece number of described single-unit canalis spinalis fixing head is 2-4 piece.
