Abstract
The utility model belongs to a medical instrument, and particularly provides an up-and-down type vertebral column fixing cross-linkage device with an elastic structure. The up-and-down type vertebral column fixing cross-linkage device is characterized by comprising a cross-linkage rod, two fastening screws and two cross-linkage bases. Meanwhile, the up-and-down type vertebral column fixing cross-linkage device is characterized in that elastic grooves are arranged in the head portions of the cross-linkage bases, through grooves are arranged in the cross-linkage bases, the two cross-linkage bases are combined together through the fastening screws and the cross-linkage rod respectively, the cross-linkage rod can be driven to press the through grooves of the cross-linkage bases by screwing the fastening screws, and therefore a linkage device can be formed, wherein the cross-linkage rod can move along the cross-linkage bases. During operation, a nail stick system is fixed in the portions, needing to be fixed, of a vertebral column, the up-and-down type vertebral column fixing cross-linkage device with the elastic structure is clamped through kidney-shaped holes by means of tools, then the cross-linkage bases are installed in a nail stick from top to bottom, the cross-linkage rod can be driven to press the protruding portions below the through grooves of the cross-linkage bases by screwing the fastening screws, the elastic grooves of the cross-linkage bases clamp the nail stick tightly, and therefore stable and reliable connection can be formed. The up-and-down type vertebral column fixing cross-linkage device is convenient and fast to install, pains of patients are reduced, and therefore a success rate of the operation is increased and recovery effect of the patients is improved. The up-and-down type vertebral column fixing cross-linkage device has the advantages of being reasonable in structure, simple to manufacture, flexible to use, ideal in effect and the like.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically is the horizontal device that connects of a kind of last following formula spinal fixation with elastic construction.
Background technology
Along with the development of biomechanics Research and material science, the application of interior technique for fixing more and more widely, to such an extent as in operative treatments such as spinal column degenerative disease, tumor of spine, the infection of wound spinal column, obtained extensive use.At present, generally will use nail-stick system and fix in spinal operation, nail-stick system generally comprises two nail rods, and the two ends of nail rod are equipped with a screw, and screw is screwed in the spinal column, needs to install the horizontal device that connects between two nail rods.The horizontal effect that connects device is that two nail-stick systems that will be installed in the spinal column both sides are connected and fixed, and reaches the effect of held stationary.But present horizontal what connect device generally is that groove by the butt hook head catches on the nail rod, skids off phenomenon in case the nail rod takes place, and the vertebral body unstability may occur, the consequence of fixing failure, thus cause the failure of performing the operation.
Summary of the invention
The purpose of this utility model is existing horizontally connect the nail rod that device may occur skid off phenomenon after implantation in order to overcome, a kind of recovery is fast, easy for installation to be connect soon for the surgeon provides, and can directly be stuck in the horizontal device that connects of last following formula spinal fixation of the band elastic construction on the nail rod from top to bottom.
The technical scheme that this utility model adopts is:
The horizontal device that connects of a kind of last following formula spinal fixation with elastic construction, comprise tranverse connecting rod, two jackscrews, two horizontal seateds, it is characterized in that: horizontal seated head is provided with elastic groove, and horizontal seated arranges dead slot, two horizontal seateds are combined by jackscrew and tranverse connecting rod separately, can drive tranverse connecting rod and oppress the saturating dead slot of horizontal seated by screwing jackscrew, form the connecting device that tranverse connecting rod can move along horizontal seated.
Horizontal seated head of the present utility model is curved, and convenience is connected with Related product; Elastic groove on the horizontal seated is in-line, prevents product from the landing of horizontal seated head, to reach the effect of retaining.
Dead slot of the present utility model is c-shaped, and quantity is two and is symmetrically distributed in the horizontal seated outside.
The last following formula spinal fixation of band elastic construction of the present utility model is horizontal to connect product that the elastic groove of device by horizontal seated can prevent from cooperating with it from the landing of horizontal seated head, has increased product stability.The utlity model has rational in infrastructurely, make simply, use flexibly, advantage such as satisfactory for result.
