The specific embodiment
Among Fig. 1, the present invention's one percutaneous guiding bone reaming tool device 10 comprises a blunt nosed guide pin 20, a guiding screw pipe 30, and a lever 40.The bulb end 21 that these blunt nosed guide pin 20 1 ends are blunt shape, these guiding screw pipe 30 central authorities have a through hole 31, one end becomes a tack tapering 32, the pipe shaft outer surface is by this tack tapering 32, be provided with a thin threaded section 33 to the other end, the other end then is provided with an application of force and meets portion 34, this lever 40 is provided with a bearing 41, the movable application of force with this guiding screw pipe 30 meets portion 34 and is connected, this bearing 41 is provided with a perforation 42, this blunt nosed guide pin 20 is movable to pass this perforation 42, and passes this tack tapering 32 along the through hole 31 of this guiding screw pipe 30.
Among Fig. 2, when the present invention uses in actual operation,, on a vertebral segments 50, directly penetrate through skin and muscular tissue 52 with a bone drill vent needle 60 earlier in an impaired skeletal tissue, and at vertebral segments 50 pedicle of vertebral arch 53 places thorns one aperture 54.
Among Fig. 3, the pricker taking-up with these bone drill vent needle 60 central authorities stays this trocar sheath 61, and with this blunt nosed guide pin 20 of the present invention, with its blunt shape bulb end 21, penetrates in this trocar sheath 61, and safe gos deep into to the vertebral body 55 of this vertebral segments 50.
Among Fig. 4,, should keep somewhere in original position by blunt nosed guide pin 20 trocar sheath 61 taking-ups of this bone drill vent needle 60, and because these blunt nosed guide pin 20 front ends are bulb shape 21, so can be very safe, be unlikely to have vertebral body 55 situations that pierce through this vertebral segments 50 and produce.
Among Fig. 5, should guide screw pipe 30 in conjunction with this lever 40, and 42 be inserted on this blunt nosed guide pin 20 with its through hole 31, perforation, be guiding with this blunt nosed guide pin 20 again, by these lever 40 application of forces, by this tack tapering 32 will these thin threaded section 33 pipe shafts guiding screw pipe 30, firm spiral is snapped at pedicle of vertebral arch 53 places of this vertebral segments 50.
Among Fig. 6, should blunt nosed guide pin 20 and this lever 40 take off taking-up, should guide screw pipe 30 keeps somewhere in original position, and because this threaded section 33 can firmly be snapped on the pedicle of vertebral arch 53 of this vertebral segments 50, so can be to the subsequent procedures operation, formation has one than major diameter, and has more the big guide pin effect of guiding stability.
Among Fig. 7, it is big slightly to get a caliber, just can be inserted in the instrumentation tubes 70 of this guiding screw pipe 30, usually this is the employed instrumentation tubes 70 of general vertebra grouting operation, along the guiding of this guiding screw pipe 30, can left and right deviation, can not change under the angle yet, smoothly the puncture of safety the pedicle of vertebral arch 53 of this vertebral segments 50, arrival can be carried out positions in the vertebral body 55 of vertebra grouting operation.
Among Fig. 8, should guide screw pipe 30 once more in conjunction with this lever 40, and reverse rotation is by taking out in this vertebral segments 50, this instrumentation tubes 70 is kept somewhere in original position, just safety and stable reach little wound, directly pass skin and muscular tissue 52 does not undermine the bone reaming work of other skeleton, nerve or vascular tissue, and follow-up vertebra grouting pipe fitting etc., just can enter in these vertebral segments 50 vertebral bodys 55 via this instrumentation tubes 70, undergo surgery.
From the above, a kind of transdermal guiding bone reaming method, this method is:
A. directly penetrate through skin and muscular tissue with a bone drill vent needle earlier, and at vertebral segments pedicle of vertebral arch place's thorn one aperture;
B. the pricker with bone drill vent needle central authorities takes out, and stays trocar sheath, and blunt nosed guide pin is penetrated in the trocar sheath with blunt shape bulb end, and safe gos deep into to the vertebral body of vertebral segments;
C. the trocar sheath with the bone drill vent needle takes out, and blunt nosed guide pin is kept somewhere in original position, and blunt nosed guide pin front end is the bulb shape, thus can be very safe, be unlikely to have the vertebral body situation that pierces through this vertebral segments and produce;
D. will guide screw pipe jointing lever, and with its through hole, the perforation be inserted on this blunt nosed guide pin, be guiding with blunt nosed guide pin again, the mat lever application of force, by this tack tapering will this thin threaded section pipe shaft guiding screw pipe, firm spiral is snapped at the pedicle of vertebral arch place of this vertebral segments;
E. blunt nosed guide pin and this lever are taken off taking-up, guiding screw pipe is kept somewhere in original position, and owing to this threaded section can firmly be snapped on the pedicle of vertebral arch of this vertebral segments, so can be to the subsequent procedures operation, formation has one than major diameter, and has more the big guide pin effect of guiding stability;
F. it is big slightly to get a caliber, just can be inserted in the instrumentation tubes of this guiding screw pipe, usually this is the employed instrumentation tubes of general vertebra grouting operation, guiding along this guiding screw pipe, can left and right deviation, can not change under the angle yet, smoothly the puncture of safety the pedicle of vertebral arch of this vertebral segments, arrival can be carried out position in the vertebral body of vertebra grouting operation;
G. will guide the screw pipe once more in conjunction with lever, and reverse rotation is by taking out in this vertebral segments, instrumentation tubes is kept somewhere in original position;
Method in view of the above, just safety and stable reach little wound, directly pass skin and muscular tissue does not undermine the bone reaming work of other skeleton, nerve or vascular tissue, and follow-up vertebra grouting pipe fitting etc., just can enter in this vertebral segments vertebral body via this instrumentation tubes, undergo surgery.
