Description
Technical field
The present invention relates to a kind of osteotomy device that is used for surgical plastic, relate in particular to a kind of variable lower jaw angle locating bone cutting device that is used for angle of mandible is implemented surgical plastic, belong to technical field of medical instruments.
Background technology
Along with enriching constantly of people's material life, the rich and varied of cultural life yearned for by people, people also day by day improve the requirement of U.S., pursuing appearance U.S.A is a kind of fashion of current people, therefore, surgical plastic beauty treatment is along with popular extremely people's favor, and angle of mandible shaping wherein one of emphasis especially.The method of angle of mandible shaping at present mainly is divided into mouthful outer approach and two kinds of mouthful interior approaches, and a mouthful outer approach is that otch plays the outside on mandibular ramus leading edge biteplane, incision skin, subcutaneous tissue and abundant blunt separation subperiosteum.The utilization technology subperiosteum of press-offing separates, expose the rear portion of middle and lower part, angle of mandible and the lower jaw member of mandibular bone ascending branch, bore labelling with roundlet, with long handle round bur and swing saw arc osteotomy by design before the art, cut saturating mandibular bone outside plate and part inner panel, the part synostosis that remains is chiseled with curved bone chisel.Separate depending on of inboard medial pterygoid, with the complete taking-up of angle of mandible that cuts down, the polishing of osteotomy line is trimmed to smooth smoothness.The advantage of this method is to appear angle of mandible and the location is easier to, clear visual field, and to lack radian be several big shortcoming of this method but leave the big and angle of mandible of otch cicatrix, damage range after the operation.Approach in the intraoral method per os, though there is not the worry of cicatrix, cause locating inaccurate owing to have tunnel vision, and otch is little and to peel off lacuna dark, lack object of reference, be difficult to correctly judge the osteotomy line position,, tend to make the osteotomy device to break away from the osteotomy line of design as careless manipulation, even because the visual field is little, how carrying out under blind looking, often apparatus can soft tissue injury cause intraoperative hemorrhage, even threat to life.The difficulty of being brought in the osteotomy often causes mandibular bone ascending branch fracture, and osteotomy does not reach expection arc angle effect, even causes osteotomy not thorough, residual osteocomma, can soft tissue injury and blood vessel, cause postoperative hematoma and massive hemorrhage once more, greatly influence surgical effect.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the present invention discloses a kind of can the quantification and by the variable lower jaw angle locating bone cutting device of setting curve osteotomy osteotomy in the angle of mandible plastic operation.
Technical scheme of the present invention is achieved in that a kind of variable lower jaw angle locating bone cutting device, comprise the flexible axle adapter sleeve, the right-hand member of described flexible axle adapter sleeve is connected with the inner medical motor that is provided with power transmission shaft, left end is provided with variable-angle clutch tooth and links to each other with the drive link right-hand member by described variable-angle clutch tooth, when being rotated counterclockwise described variable-angle clutch tooth to a certain degree the time, described flexible axle adapter sleeve and drive link are relaxed state, the head spindle of the left end connecting band drill bit of described drive link, described head spindle top is provided with the drill bit locking plate, has the scale locating rod on the drive link, the scale locating rod is connected to drill bit locking plate and mobile drag hook scale in the both sides of drive link, mobile drag hook scale and scale reference column junction are equipped with spring leaf, head spindle, drill bit and mobile drag hook scale and drive link are fixed in one, firmly pull-up and rotate drive link this moment, head spindle, drill bit, mobile drag hook scale also along with rotating together, can be adjusted to the angle that needs arbitrarily.Mobile drag hook scale width is 5mm.
Described mobile drag hook scale is provided with drag hook, anti-slop serrations, chute and small sircle hole, spring leaf passes small sircle hole and is fixed on the described drive link, it is 2mm and tangent small sircle hole that mobile drag hook scale is provided with 6--10 diameter, drill bit can pass chute makes mobile drag hook scale be connected with head spindle, when the drill bit locking plate is resisted against the scale reference column, drill bit locking plate counter-clockwise swing, when drill bit locking plate disengaging scale reference column, drill bit presents relaxed state, can freely take out.Drill bit on the head spindle is detachable, and drill bit passes chute mobile drag hook scale is fixed, and spurs the drill bit locking plate counterclockwise, the drill bit locking plate breaks away from the scale reference column, can take off drill bit this moment, and press spring leaf to the drive link direction, and mobile drag hook scale can be parallel to the drive link direction and move.
The present invention has following advantage with respect to prior art:
1, the present invention can freely rotate the angle of drive link, makes operator to control flexibly.
2, the present invention is simple to operate, and operating time is short, can significantly reduce complication, the safety coefficient height.
