Description
Technical field
The present invention relates to a kind of multifunctional electric Invasive lumbar fusion device propeller, belong to medical apparatus technical field.
Background technology
As everyone knows, the lumbar intervertebral fusion device shape major part of application is rectangular build clinically at present, and the fusion device of small part is crescent shape.For squeezing into conveniently, fusion device is made generally in and is about 25mm, the shape of wide and high about 10mm left and right, and inner hollow can pack broken bone into.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.Generally need bilateral to carry out same operation.There are the following problems for this technology: one, in art, want to squeeze into fusion device, must firmly beat with hammer, and larger to perineural disturbance.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 simultaneously.Two, when fusion device long axis direction is squeezed into, be the consideration of neuroprotective aspect, the direction of fusion device is subject to significant limitation, can only vertical direction or oblique squeezing into a little, and the requirement that makes fusion device be other direction cannot realize.Because intervertebral space is narrower, can only when squeezing into, adjust in advance the direction of fusion device simultaneously, squeeze into rear very difficult adjustment direction.While three, performing the operation, a side can only be squeezed into one piece of fusion device.A lot of doctors often squeeze into one piece of fusion device a skew back shape, in the hope of bilateral equilibration, but the fusion area of one piece of fusion device is less, and oblique fusion device cannot guarantee the bilateral equilibration of spinal column, to bilateral pedicle screw stress inequality, may cause interior fixing loosening inefficacy.In order to expand fusion face and to keep two lateral balances, apply rectangular fusion device and generally need in both sides, respectively squeeze into one piece.Both sides operation has increased the risk of operating time and nerve injury.Four, pound fashionablely, may damage upper and lower terminal plate of vertebral body, caused fusion device to be lowered into vertebral body, thereby affected syncretizing effect.Five, the fusion area of the fusion device of crescent shape is less, no matter is one-sided or bilateral can only be squeezed into one piece, cannot squeeze into many pieces of fusion devices.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, multifunctional electric Invasive lumbar fusion device propeller easy to use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multifunctional electric Invasive lumbar fusion device 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, in the small of the stock, be provided with motor and variator, in gun barrel, be provided with threaded rod, in described sleeve, be provided with rear push pedal, described gun barrel and described sleeve join, and the rear push pedal being provided with in described threaded rod one end and described sleeve is joined.
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, the threaded rod phase interlock being provided with in gear and gun barrel.
Further, described gun barrel has trigger-type power supply and speed-regulating switch, and power supply and speed-regulating switch and power supply join.
Further, described sleeve rear portion is straight tube shape, and it is flat-shaped that front portion is that arc is, and arc inner side is provided with observation window, and described barrel forward end is outlet.
Further, be provided with the push rod of making of elastomeric material in described sleeve front portion, push rod front end is front push pedal, and rear portion is rear push pedal.
During use, first propeller is combined, then the fusion device that fills up broken bone is put into arc sleeve along the direction of described barrel forward end outlet, front push pedal is withstood on to the rear side of fusion device.In art, first go the squeezing into of many pieces of pedicle screws of related sections, interior fixed bar is not installed or only loosely interior fixed bar is fixed on screw, maintain suitable local stability.By a side facet joint arthrectomy fraction of Fusion levels, or excise upper and lower zygapophysial joints completely, appear canalis spinalis and upper and lower nervous tissue around.Separately neural adhesion around, the next nerve root in dural sac and canalis spinalis is retracted to the inside, appear canalis spinalis inner structure, complete the excision that causes 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, propeller front end (arc up or down) is to flat-shaped and in articular process inner side or outside, puts into intervertebral space, dextrorotation turn 90 degrees, and intervertebral space is strutted, and adjust its Way out with handle.Broken bone piece or bone mud first can be pushed in intervertebral space by fusion device.Power-on and speed-regulating switch again, starter motor pushes the fusion device in propeller in intervertebral space with push pedal carefully.Movable propeller, can further adjust fusion device direction.Carry out squeezing into of second piece of fusion device.Still there is cavity in the surrounding of fusion device now, broken bone piece 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.Fixed bar in bilateral is installed, after longitudinal pressing, is tightened interior secured adjusted valve.The position of X-ray examination inside-fixture, as the position of fusion device is not good, unclamp fixed bar in bilateral, with the propeller of large size, expand the height of intervertebral space, with horn shape embedded device, adjust the position backed off after random propeller of fusion device, the pressurization of carrying out again bilateral screw is 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 to direction and push in intervertebral space, and be driven into offside, the interspinous support of looking after offside merges, the risk that does not need the patient of decompression to exempt offside operation technique for offside.Propeller can expand the height of intervertebral space, facilitated entering of fusion device, needn't use bone hammer brute force to squeeze into intervertebral space, only need opening power and speed-regulating switch starter motor push rod that fusion device is pushed to intervertebral space, avoid destruction to soleplate and to neural vibration influence.
