Abstract
The invention relates to a medical distraction osteogenesis device, in particular a built-in arc-shaped distraction osteogenesis device which has the key technology that both ends of an internal cylindrical guide path bent in an arc way are fixedly provided with a left fixed wing and a right fixed wing; a movable wing fixedly connected with a roller at the leftmost end is matched with and connected with the internal cylindrical guide path in a slide way between the left fixed wing and the right fixed wing along the preset arc of the internal cylindrical guide path; and the internal cylindricalguide path is filled with a plurality of rollers closely matched and connected with the internal cylindrical guide path in a slide way. In a distraction osteogenesis operation, the invention can carry out distraction osteogenesis along any directions, enhances the efficiency of the operation, relieves pains of patients and reduces the cost of the operation.
Description
Technical field
The present invention relates to a kind of medical distraction osteogenesis device, particularly a kind of built-in arc-shaped distraction osteogenesis device.
Background technology
(Distraction Osteogenesis is after cutting by bone, to use special traction apparatus DO) to the distraction osteogenesis art, and slowly tractive forms the purpose that new bone reaches the skeleton prolongation thereby make in the osteotomy gap.The distraction osteogenesis technology is the most normal to be applied to prolong jawbone, treats the micrognathia that all kinds of reasons cause, and can make jawbone prolong 10-30mm.At present, distraction device commercially available and clinical use all adopts spiral power transmission principle to realize.Because the structural characteristics of worm drive, can only be at the single direction distraction osteogenesis, i.e. rectilinearity distraction osteogenesis.And the skeletonization demand of patient's mandibular bone is varied, varies with each individual, and a considerable amount of patients are arranged, and often needs conversion skeletonization direction, and promptly the skeletonization direction is non linear arc.Therefore, operation is adopted two unidirectional distraction osteogenesis device duplexs often or is finished complicated multidirectional distraction osteogenesis by repeatedly performing the operation.So can the extended treatment cycle, increase medical treatment cost, bring the painful and too much financial burden of the unnecessary human body to the patient.
Summary of the invention
The purpose of this invention is to provide a kind of built-in arc-shaped distraction osteogenesis device, can be according to the demand of distraction osteogenesis art, but be provided with one vertically to level to the interior garden of equal arc-shaped bend post gathering sill, post guiding in garden in utilizing, screw rod rotates and has an effect, roller extruding power transmission, the arching trajectory distraction osteogenesis of movable wing garden post gathering sill in the extruding promotion lower edge of roller.Fully overcome the deficiencies in the prior art.
The present invention solves the scheme that its technical problem adopts: the two ends of the interior garden post gathering sill of arc-shaped bend are set with left and right sides fixed-wing.The movable wing that is connected with the high order end roller is connected with interior garden post gathering sill tight fit slidingtype between left and right fixed-wing along the default arc of interior garden post gathering sill.Be filled with the roller more than at least 8 that is connected with its tight fit slidingtype in the interior garden post gathering sill between movable wing and the power transmission screw rod.Detachable swivel nut is connected with interior garden post gathering sill right-hand member screw-type, is connected with power transmission screw flight formula.Nut is arranged on the power transmission screw rod in the detachable swivel nut outside.Interior garden post gathering sill and right fixed-wing are connected partly and detachable swivel nut is a linearity.At least can fill the roller more than 3 in the detachable swivel nut.
Good effect of the present invention: compared with prior art, the present invention is applied in the built-in distraction osteogenesis art, especially need vertically to level in the operation that is the arc skeletonization, disposablely can finish non linear distraction osteogenesis.Reach that same therapeutic purposes operation number of times is few, expense is low, has alleviated patient's misery, has improved operation efficient.

Fig. 2 is interior garden post gathering sill A-B profile.
Among the figure, 1, left fixed-wing, 2, interior cylinder gathering sill, 3, movable wing, 4, roller, 5, right fixed-wing, 6, detachable swivel nut, 7, nut, 8, the power transmission screw rod, 9, roller slot.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.As shown in Figure 1, according to the curve requirement of patient's mandibular bone skeletonization direction, the interior garden post gathering sill 2 of arc-shaped bend is set, its two ends fixedly install left fixed-wing 1 and right fixed-wing 5.The movable wing 3 that is connected with foremost roller 4 can be connected with interior garden post gathering sill 2 tight fit slidingtypes between left and right fixed-wing 1,5 along the default arc of interior garden post gathering sill 2.Be filled with the roller more than at least 84 that is connected with its tight fit slidingtype in the interior garden post gathering sill 2 between movable wing 3 and the power transmission screw rod 8.Detachable swivel nut 6 is connected with interior garden post gathering sill 2 right-hand member screw-types, is connected with power transmission screw rod 8 screw-types.Nut 7 is arranged on the power transmission screw rod 8 in detachable swivel nut 6 outsides.Interior garden post gathering sill 2 is connected partly with right fixed-wing 5 and detachable swivel nut 6 is linearity.At least can fill the roller 4 more than 3 in the detachable swivel nut 6.As shown in Figure 2, the roller slot 9 of interior garden post gathering sill 2 is semi-open property, and roller 4 pushes power transmission in roller slot 9.
The specific embodiment of the invention as shown in Figure 1, at first, according to operation plan, but default one vertically to level to the interior garden of equal arc-shaped bend post gathering sill 2; Secondly, in the operation implementation process, after bone cuts, left fixed-wing 1 and right fixed-wing 5 are solidly connected with a support bone piece, movable wing 3 is solidly connected with movable bone piece; With the roller 4 of filling more than at least 8 in the roller slot 9 of interior garden post gathering sill 2; Detachable swivel nut 6 opens with power transmission screw rod 8 maximums, as often as possible roller 4 is full of in the detachable swivel nut 6, then detachable swivel nut 6 is tightened with interior garden post gathering sill 2.At this moment, rotate power transmission screw rod 8, by the power transmission of roller 4, make movable wing 3 and the movable bone piece that is connected along the default slow slippage of arching trajectory of interior garden post gathering sill 2.When the bone cut-off reaches when necessarily requiring, nut 7 and detachable swivel nut are tightened, promptly the fixing force transfer screw rod 8.Certain hour or all after dates, the bone cut-off overgrows with new bone, needs again bone to cut.Need not dismantle left and right fixed-wing 1,5 and movable wing 3 this moment, only need detachable swivel nut 6 is unloaded, power transmission screw rod 8 is opened once more to greatest extent, refill the roller 4 of some in detachable swivel nut 6, the working procedure above repeating can reach purpose of the present invention.
