Description
Technical field
The present invention relates to a kind of electric multifunctional interbody fusion cage propeller, belong to medical apparatus technical field.
Background technology
As everyone knows, the lumbar intervertebral fusion device shape major part applied clinically is at present cuboid-type, and the fusion device of small part is crescent shape.For squeezing into conveniently, fusion device is made generally in and is about 25mm, and the shape of wide and height about about 10mm, inner hollow can load broken bone.In art, dural sac and nerve root are retracted to the inside, vacate enough spaces and between upper and lower nerve root, Invasive lumbar fusion device is squeezed into by its long axis direction.Bilateral is generally needed to carry out same operation.There are the following problems for this technology: one, want in art to squeeze into fusion device, firmly must beat with hammer, larger to perineural disturbance.Simultaneously because fusion device is close to upper and lower nerve root, when fusion device is squeezed into, peripheral nerve is in unprotect state, therefore fusion device edge is easy to damage upper and lower nerve root and inner side dural sac.Two, when fusion device long axis direction is squeezed into, be the consideration of neuroprotective aspect, the direction of fusion device is subject to obvious restriction, can only vertical direction or obliquely a little to squeeze into, and makes fusion device be that the requirement in other direction cannot realize.Simultaneously because intervertebral space is narrower, the direction of fusion device can only be adjusted when squeezing in advance, squeezing into rear very difficult adjustment direction.Three, during operation, one piece of fusion device can only be squeezed in side.A lot of doctor is often oblique in side squeezes into one piece of fusion device, in the hope of bilateral equilibration, but the fusion area of one piece of fusion device is less, and oblique fusion device cannot ensure the bilateral equilibration of spinal column, unequal to bilateral pedicle screw stress, the loosening inefficacy of internal fixtion may be caused.In order to expand fusion face and keep two lateral balances, applying rectangular fusion device generally needs respectively to squeeze into one piece in both sides.Both sides operation adds the risk of operating time and nerve injury.Four, pound fashionable, upper and lower terminal plate of vertebral body may be damaged, cause fusion device and be lowered into vertebral body, thus affect syncretizing effect.Five, the fusion area of the fusion device of crescent shape is less, no matter is one-sided or bilateral can only squeeze into one piece, cannot squeeze into many pieces of fusion devices.
Summary of the invention
Technical problem to be solved by this invention overcomes above-mentioned the deficiencies in the prior art, provides a kind of simple structure, electric multifunctional interbody fusion cage propeller easy to use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric multifunctional interbody fusion cage propeller, it comprises motor and sleeve, it is characterized in that: described motor housing is pistol type, be provided with the small of the stock, gun barrel, power supply and speed-regulating switch, be provided with motor and variator in the small of the stock, in gun barrel, be provided with threaded rod, in described sleeve, be provided with rear push pedal, described gun barrel connects with described sleeve, and described threaded rod one end connects with the rear push pedal be provided with in described sleeve.
Further, described in be located at electric machine main shaft in the small of the stock upward, electric machine main shaft upper end is provided with gear, and gear is engaged mutually with the threaded rod be provided with in gun barrel.
Further, described gun barrel has trigger-type power supply and speed-regulating switch, and power supply and speed-regulating switch connect with power supply.
Further, described sleeve rear portion is straight tube shape, and front portion is arc is flat-shaped, and arc shaped inside is provided with observation window, and described barrel forward end is outlet.
Further, be provided with the push rod made of elastomeric material in described sleeve front portion, push rod front end is front push pedal, and rear portion is rear push pedal.
First propeller is combined during use, then arc sleeve is put in the direction that the fusion device filling up broken bone exports along described barrel forward end, front push pedal is withstood on the rear side of fusion device.In art, the squeezing into of many pieces of pedicle screws of the first involved sections of row, does not install internal fixtion bar or is only loosely fixed on screw by internal fixtion bar, maintaining suitable local stability.By the side facet joint arthrectomy fraction of Fusion levels, or excise lower articular completely and to dash forward joint, appear canalis spinalis and around nervous tissue up and down.Separately neural adhesion around, dural sac and the next nerve root of intraspinal tube are retracted to the inside, appear intraspinal tube structure, complete the excision causing pressure factor, in intervertebral space, strike off the lower edge of upper vertebral body and the upper limb endplate cartilage of the next vertebral body, until subchondral bone, by propeller front end (arc up or down) in flat-shaped inside articular process or outside put into intervertebral space, dextrorotation turn 90 degrees, and is strutted by intervertebral space, and adjusts its Way out with handle.Broken bone block or bone mud first can be pushed in intervertebral space by fusion device.Power-on and speed-regulating switch again, the fusion device in propeller pushes in intervertebral space with push pedal by starter motor carefully.Movable propeller, can adjust fusion device direction further.Carry out squeezing into of second piece of fusion device.Now still there is cavity in the surrounding of fusion device, broken bone block or bone mud can be pushed in intervertebral space internal cavity by propeller, and be located at predetermined position, separately with depression bar by broken bone compacting.Take out propeller.Bilateral internal fixtion bar is installed, after longitudinal pressing, tightens internal fixtion control valve.The position of X-ray examination inside-fixture, position as fusion device is not good unclamps bilateral internal fixtion bar, the height of intervertebral space is expanded with the propeller of large size, with the position backed off after random propeller of horn shape embedded device adjustment fusion device, the pressurization carrying out bilateral screw is again fastening, and makes hypocentrum edge and fusion device close contact.
The invention has the beneficial effects as follows: by angle of rake effect, fusion device is changed arbitrarily direction and push in intervertebral space, and be driven into offside, the interspinous support looking after offside merges, and does not need the patient of reducing pressure to exempt the risk of offside operation technique for offside.Propeller can expand the height of intervertebral space, facilitate entering of fusion device, bone hammer brute force need not be used to squeeze into intervertebral space, only need opening power and speed-regulating switch starter motor push rod that fusion device is pushed intervertebral space, avoid the destruction to soleplate and the vibration influence to nerve.
