Abstract
A stretching machine with Ti-Ni memory alloy. The two ends of the stretching machine are fixing legs, the middle portion thereof is the part for forcing in the configuration of S,C or Z shape. The machine is made of Ti-Ni shape memory alloy, the temperature for resuming the original form after memory treatment is 30-33degree C. When used, first cutting a bone, perforating in cut bones, inserting the stretching machine which has been compressed after cooling and deformed, stitching wounds and embedding the machine; the stretching machine will automatically resume the original form at the temperature of human bodies, which will expand gaps between bones; then new bones will form in gaps, bones will be extended or widened.
Description
Technical field
The present invention relates to a kind of titanium-nickel memory alloy pull-stretch device and manufacture method thereof, is the operation device that is applied to the facial distraction osteogenesis of jaw, belongs to the oral surgery instrument field.
Background technology
The distraction osteogenesis technology is meant utilizes natural sutura, or the bone people formed the gap for blocking, place the stretching device at the spatium interosseum place, but the gap is enlarged in the human body tolerance range by certain speed and frequency by its reinforcing, in the spatium interosseum that stretching increases, form new bone, thereby reach the purpose that makes bone prolongation or broadening.This technology does not need to use graft materials, can obtain the soft tissue that synchronous stretching prolongs again, has made full use of the growth potential of body, allow body lack what long what, lack what long what.The facial bone stretching of at present domestic and international existing jaw device owing to can't realize automatic driving-force adding, all is half embed-type, augmentor must be stayed in the oral cavity or facial, leaves over open wound, infects easily, also influences patient's comfortableness and attractive in appearance.
Summary of the invention
The objective of the invention is to propose a kind of titanium-nickel memory alloy pull-stretch device and manufacture method thereof, its energy automatic driving-force adding, volume is little, is embedded in fully in the body, and easy infection is not easy to use, comfortable.
Ti-ni shape memory alloy has good shape memory function, can be out of shape arbitrarily in 0～5 ℃ brine ice, recovers shape under human body temperature automatically.The titanium-nickel memory alloy pull-stretch device that utilizes this character to make for the internal fixation operation device that memory alloy wire is made, is made up of fixing and afterburning two parts.Standing part is two fixing feet at stretching device two ends, and is vertical with surface of bone, can make a call to two micropores on surface of bone, is inserted into, and plays the fixedly effect of stretching device.Afterburning part is vertical with standing part, can be close to surface of bone, and it is Z-shaped that its shape can be designed to S shape, C shape, Z-shaped or many songs according to required different strength.During use, carry out bone-culting operation earlier, form stretching bone piece, again at spatium interosseum two side perforatings, be inserted in the stretching device of cooling back compression in the brine ice, stretching device quantity can put into one as required to several, and is behind the sew up wound that it is embedding fully; The stretching device opens complex automatically under human body temperature, promotes spatium interosseum and enlarges, and form new bone in consequent gap, thereby reach the purpose that makes bone prolongation or broadening.
The advantage of titanium-nickel memory alloy pull-stretch device is that volume is little, and shape memory function is arranged, and the energy automatic driving-force adding can be embedded in the body fully, and easy infection is not easy to use, comfortable.

Regional osteotomy by Fig. 5 mandibular bone (6) need increase forms, and (9) two side perforatings in the osteotomy gap insert the stretching device (7) of compression.
Enlarged by spatium interosseum (9) after Fig. 6 stretching device (7) complex, stretching bone piece (8) raises.
By the side osteotomy of Fig. 7 mandibular bone (6) near damaged (10), form stretching bone piece (8), (9) two side perforatings in the osteotomy gap insert the stretching device (7) of compression.
Enlarged by spatium interosseum (9) after Fig. 8 stretching device (7) complex, stretching bone piece (8) arrives the defective region opposite side.
The specific embodiment
The stretching device of different shape is bent by the Ti-Ni marmem silk respectively and forms, and through hot-working the alloy silk is bent into required form earlier, and 500 ℃ of heat treatments are 1 hour again, and making its complex temperature is 30～33 ℃.Titanium-nickel memory alloy pull-stretch device can be used for alveolar bone heighten operation, jaw defect reparation and jawbone and prolongs fields such as art.When alveolar bone is put down owing to reasons such as atrophy or tumor resection become low, when influence is had a denture made, need carry out the alveolar bone heighten operation: the regional osteotomy that need increase at mandibular bone (6), form stretching bone piece (8), (9) two side perforatings in the osteotomy gap, be inserted in the stretching device (7) of cooling back compression in the brine ice, the stretching device is embedded in the body fully behind the sew up wound; Postoperative stretching device (7) is complex gradually, and stretching bone piece (8) raises, and spatium interosseum (9) enlarges, and forms new bone in the gap, thus the alveolar bone that acquisition is increased.When jawbone is damaged owing to reasons such as wound or tumor resection exist, can repair by the distraction osteogenesis operation: in the side osteotomy of mandibular bone (6) near damaged (10), form stretching bone piece (8), (9) two side perforatings in the osteotomy gap, be inserted in the stretching device (7) of cooling back compression in the brine ice, the stretching device is embedded in the body fully behind the sew up wound; Postoperative stretching device (7) is complex gradually, and spatium interosseum (9) enlarges, and stretching bone piece (8) arrives the defective region opposite side, forms new bone in the gap of its back, thus the jawbone of repair deficiency.
