Since the technical scheme is used, the utility model discloses can pinpoint the superior articular process position, messenger position casing rides to stride and be difficult for the landing on superior articular process, guarantees to grind the safe, stable of bone drill mill bone in -process, can control the degree of depth of mill bone again, avoids grinding the bone and crosses deeply and harm dura mater bag and nerve root, grinds and removes the scope except that sclerotin in -process accessible removes position casing and enlarges the mill.
Description
Technical field
This utility model relates to medical instruments field, bores bone object more particularly to a kind of articular process.
Background technology
Prolapse of lumbar intervertebral disc is Spinal fractures commonly encountered diseases and frequently-occurring disease, is due to after intervertebral disc generation degenerative change, Anular disruption, and Nucleus pulposus is to canalis spinalis, and the caused lumbago and skelalgia of the tissue such as stimulation, pressuring neural root, blood vessel or spinal cord, numbness etc. are the disease led.Patient pain is often relatively acutely, it is impossible to walking, has a strong impact on life.Traditional operation treatment wound is big, hemorrhage many, post-operative recovery slow, and there is postoperative long-term chronic problem and the untoward reaction such as relapse rate is high.Along with being rooted in the hearts of the people of Wicresoft's theory, foramen intervertebrale lens technology is arisen at the historic moment.The remarkable advantages such as, wound little, safety high, few intercurrent disease, determined curative effect wide by feat of indication, foramen intervertebrale lens is popularized rapidly and is developed.Smooth enforcement is expected in foramen intervertebrale lens operation, and accurately implanting of working column is crucial.Owing to working column to be implanted to intraspinal tube by this slype of intervertebral foramina; therefore; patient is had to the situation of lumbar vertebra congenital dysplasia or regression hypertrophy etc.; it is easy to, by the abnormal bone of articular process, operative approach is formed stop, causes that working column cannot implant to tram failure.In traditional method, insert brill bone object at intervertebral foramina place and can abrade the part abnormal bone at articular process place, but, limitation due to device design, bore bone object when abrading the abnormal bone at articular process place, position and the degree of depth are difficult to control to, bore bone object end and enter canalis spinalis, it is easy to be damaged to dural sac and nerve root, the safety of patient it is difficult to ensure that when therefore boring bone, namely existing method cannot removing abnormal bone as much as possible under the premise that security is guaranteed, enough visible angle cannot be provided for endoscope, and then make the pathological interspinal dish can extractd in art limited, affect operative effect.
Utility model content
The technical problems to be solved in the utility model is to overcome drawbacks described above, it is provided that a kind of controlling drilling position of bone is put the articular process with the degree of depth and bored bone object.
For solving the problems referred to above, this utility model be the technical scheme is that
A kind of articular process bores bone object, including sleeve pipe, is provided with drilling rod in described sleeve pipe, described drilling rod one end is provided with threaded rod, the other end is provided with drill bit, and described threaded rod is connected to operation handle, and described threaded rod is provided with nut, described sleeve pipe is provided with some guide grooves, being movably set with third connecting rod in described guide groove, described third connecting rod is hinged with second connecting rod, and described second connecting rod is hinged with first connecting rod, described first connecting rod is hinged with sleeve pipe, is provided with positioner between described third connecting rod and sleeve pipe.
Improve as one: described positioner includes fixing bolt, and described third connecting rod is provided with screwed hole.
Improve as one: described drill bit is fluted drill, chit drill, or end face has the trepan of annulus sawtooth.
As one improve: described drilling rod have axially through seal wire jack hole.
Improve as one: described third connecting rod end is provided with a fastener.
Improve as one: described support head shapes is spherical.
Improve as one: described fastener is elastic ball.
Owing to have employed technique scheme, this utility model can be accurately positioned superior articular process position, locating sleeve is made to straddle not easily landing on superior articular process, ensure the safety in mill bone drill mill bone process, stable, the degree of depth of mill bone can be controlled again, mill bone is avoided to cross deep and be damaged to dural sac and nerve root, abrade in sclerotin process and can expand removing scope by running fix sleeve pipe, there is provided accurately for working column, broad implantation space, enough visible angles are provided for endoscope, and then create favorable conditions for thoroughly extracing of pathological interspinal dish, this utility model simple in construction, and it is easy to operate when being used for performing the operation.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
