Embodiment one, and referring to Fig. 1, Fig. 2, shown in Figure 5, the operating procedure of the present invention when carrying out the rectangle osteotomy is as follows:
At first determine art bone upper end osteotomy anchor point and art bone lower end osteotomy anchor point before the art, and soft tissue is cut an osculum, put into the osteotomy drill bit, accomplish fluently art bone upper end osteotomy locating hole and art bone lower end osteotomy locating hole at art bone upper/lower terminal respectively.Confirm the osteotomy point according to vertical osteotomy line position of in advance design again, and it is stand-by that soft tissue is cut two osculums at the osteotomy point two ends of confirming, the vertical Wicresoft of tubular bone osteotomy device is placed on the art bone, a pair of auxiliary positioning needle inserted respectively and the fixing upper end osteotomy locating hole and art bone lower end osteotomy locating hole of having accomplished fluently on, and with the upper and lower a pair of spiro cap of auxiliary positioning needle at screw fastening needle shaft upper/lower terminal, with its rotational lock, as anchor point.Main positioning needle 2 and osteotomy drill bit 1 are inserted respectively in the main positioning needle jack 6, osteotomy drill bit jack 5 of sleeve pipe 3, main positioning needle 2 tops are connected with main positioning needle handle 25, and then osteotomy drill bit 1 top is connected with drive motors 24 again.Adjust guide rail graduated scale 15 with reference to the location, adjust on the guide rail 13 in the location first, adjust the position of main positioning needle 2 and osteotomy drill bit 1, sleeve pipe 3 is adjusted to the designed angle of operation plan by the angle adjustment graduated disc on the cover pipe clip, aim at and insert the little incision of soft tissue and near the art surface of bone, and with screw 13 pad, chuck and cover pipe clip are connected and fixed.
When carrying out the bone-culting operation operation, first the soft tissue of art bone upper end soft tissue incision is peeled off along art bone central point direction and art bone, then handle osteotomy drill bit 1 and get out first oblique angle, art bone upper end osteotomy boring at the osteotomy place, and main positioning needle 2 interted in this hole, then according to operating prediction scheme before the art, according to the angle adjustment graduated disc 9 on the cover pipe clip upper surface, the angle of rotation adjusting sleeve pipe clip, go out the oblique angle osteotomy boring of second art bone upper end with osteotomy drill bit 1 at a sidetracking of main positioning needle 2, interspersed osteotomy positioning needle 2, again take second hole osteotomy positioning needle as the center of circle, with sleeve rotating handle 4 Rotate 180s of sleeve pipe 3 °, handle again osteotomy drill bit 1 and get out the oblique angle osteotomy boring of the 3rd art bone upper end at the opposite side of main positioning needle 2, then extract the osteotomy drill bit, again main positioning needle 2 is moved in second or the 3rd hole and locate, handle again osteotomy drill bit 1 and get out the oblique angle osteotomy boring of the 4th art bone upper end at the osteotomy place, as can be seen from the figure play oblique angle, art bone upper end osteotomy boring 28 and do not played oblique angle, art bone upper end osteotomy boring 29, successively by the above-mentioned steps repetitive operation, until the art bone is sectioned to a half of art bone total length.To overlap screw 12 rotations of pipe clip 7 unclamps again, and will overlap pipe clip 7 and be inconjunction with the chute 14 interior slips of pad 10 and chuck 11 being adjusted guide rail 13 in the location, the soft tissue that cover pipe clip 7 is moved to the lower end cuts the osculum place, according to the aforesaid operations method osteotomy of holing from the bottom to top, its oblique angle, art bone art bone lower end osteotomy boring intersects with the hole of oblique angle, art bone upper end osteotomy boring, directly causes the art bone is sectioned.
After finishing the vertical osteotomy of tubular bone, the position that the revoling tube rotary handle is 4 to 90 °, then the auxiliary positioning needle in the removal surgery bone lower end osteotomy locating hole 27, and take this auxiliary positioning needle as the axle center, adjust the sleeve pipe 3 of mobile osteotomy device to the horizontal osteotomy of tubular bone place, begin with osteotomy drill bit 1 along the tubular bone cross drilling, insert main positioning needle 2 after the boring, the position of revoling tube rotary handle to 180 ° again, and then laterally bore second hole with osteotomy drill bit 1 along tubular bone, repeatable operation laterally sections tubular bone one end according to this, and above-mentioned boring can be vertical osteotomy boring or the boring of oblique angle osteotomy.
After finishing aforesaid operations, again the auxiliary positioning needle of lower end is inserted location in the osteotomy locating hole 27 of art bone lower end, then an auxiliary positioning needle of removal surgery bone upper end osteotomy locating hole 26, and take this auxiliary positioning needle as the axle center, adjust the sleeve pipe 3 of mobile osteotomy device to the horizontal osteotomy of tubular bone place, begin with drill bit 1 along the tubular bone cross drilling, insert main positioning needle 2 after the boring, rotate again the position of rotary handle to 180 °, and then laterally bore second hole with osteotomy drill bit 1 along tubular bone, repeatable operation laterally sections the tubular bone upper end according to this.After finishing the vertical osteotomy of above-mentioned tubular bone, can carry out horizontal drawing-off treatment.
Embodiment two: referring to Fig. 1, Fig. 2, Fig. 3, shown in Figure 6, the present invention also can be suitable for soft tissue slitting-up mode and carry out the vertical bone-culting operation of tubular bone.When implementing bone-culting operation, at first determine the upper and lower osteotomy anchor point of art bone, then accomplish fluently art bone upper end osteotomy locating hole 26 and art bone lower end osteotomy locating hole 27 with the osteotomy drill bit, and according to the vertical osteotomy line position affirmation osteotomy point that designs in advance, and with soft tissue longitudinally the osteotomy position cut one stand-by with the isometric otch of osteotomy line, the vertical Wicresoft of tubular bone osteotomy device is placed art bone place, and its operational approach is identical with embodiment one.
Embodiment three: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 7, shown in Figure 8, that the present invention carries out is Z-shaped, during S shape osteotomy, operational approach is identical with bone-culting operation step and the method for embodiment one, just after the tubular bone longitudinal drilling osteotomy, the opposite direction that blocks in the top and bottom of tubular bone cross drilling osteotomy, make it to form the Z-shaped osteotomy of longitudinal traction position 22 or longitudinal traction S shape osteotomy position 23, become Z-shaped art bone osteotomy section or the S shape, satisfy the needs of the vertical drawing-off treatment of tubular bone.
The above embodiment; only be the more representational specific embodiment of the present invention; but institute of the present invention resist technology scheme is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; can from direct all changes or the replacement of deriving or expecting easily of content disclosed by the invention, all should be encompassed within protection scope of the present invention.
