Description
Technical field
The invention belongs to medical instruments field, relate to a kind of adjustment height anchor and go out formula Invasive lumbar fusion device.
Background technology
Vertebra degeneration is spinal surgery disease common clinically, has a strong impact on minimal invasive treatment and work, and operative treatment is frequently as the final selection of patient.The modus operandi of spinal treatment is developed to interbody fusion relatively common at present by simple lumbar discectomy, and have developed a series of fusion formula in being perfectly combined between pursuit vertebral body, such as intertransverse process autograft fusion art, Minor articulus bone graft fusion, H vertebral plate bone graft fusion etc..
In recent years, for improving the success rate of intervertebral fusion operation, reducing extenal fixation dependency, improve and keep the curvature of spinal column, Invasive lumbar fusion device arises at the historic moment.Since Invasive lumbar fusion device is applied to interbody fusion treatment vertebrae disease and obtains success, various Invasive lumbar fusion devices are come out one after another, and are widely accepted by clinic.It is stable that Invasive lumbar fusion device can effectively maintain anterior spinal, retains disc height, meets spinal column heavy burden requirement, be conducive to the rehabilitation of patient.
But the Invasive lumbar fusion device technology currently used there is also certain problem, and the Invasive lumbar fusion device used clinically at present mostly is fixed structure, it is more difficult to grasp vertebral body reconstruction height, secondary adjustment can not be carried out after implantation；As time goes on or the motion of patient and, Invasive lumbar fusion device can loosen and skids off or be implanted into sinking etc., stable after therefore needing clinically to research and develop a kind of implantation, the Invasive lumbar fusion device of secondary adjustment can be carried out.
Summary of the invention
In order to solve the deficiencies in the prior art, it is an object of the invention to provide a kind of adjustment height anchor and go out formula Invasive lumbar fusion device, use this Invasive lumbar fusion device can regulate intervertebral height, prevent the slippage of Invasive lumbar fusion device simultaneously, decrease the fixation procedure of pedicle screw.
To achieve these goals, the present invention adopts the following technical scheme that
The invention provides a kind of adjustment height anchor and go out formula Invasive lumbar fusion device, including upper main board 1, lower main board 2, it is positioned at the bone grafting hole 3 on main board, it is positioned at the upper sleeve pipe 9 on main board 1, it is positioned at the setting of casing 10 on lower main board 2, it is positioned at the vertebra nail 11 of sleeve pipe, described upper main board 1 front side wall is tightened up a screw hole 51 and lower screw hole 61, described hole 51 of tightening up a screw is inserted and adjusts oncomelania silk 52, described lower screw hole 61 inserts and heightens screw 62, described tune oncomelania silk 52 there is dentalation 523, follow closely 11 phases to be engaged with vertebra, oncomelania silk 52 is adjusted to drive vertebra nail 11 motion by rotating, adjust oncomelania silk 52 to follow closely 11 phases with vertebra and be engaged place without sleeve pipe obstruct, described heightening has ring toothing 623 on screw 62, it is engaged with sawtooth 102 phase on setting of casing 10, heightening screw 62 by rotation drives sleeve pipe to move, thus changing disc height, it is hollow structure 7 by the part of screw when lower main board 2 moves.
