Abstract
The vertical double-axis jawbone myotasis device of the utility model is a medical appliance used for the deformity correction to the short jaw facial bone. The vertical double-axis jawbone myotasis device comprises a transverse traction device and a longitudinal traction device which are mutually intersected and fixed perpendicularly. Each traction device comprises a casing 1, a spacer pin 2, a screw rod 3, a central axis 4, and a positioning plane 5. The screw thread 32 of the screw rod 3 is matched with the inner screw in the central axis 4. One end of the casing 1 is sheathed outside the screw head 33 of the screw rod 3, and the other end of the casing 1 is sheathed outside the central axis 4. The spacer pin 2 is arranged on the casing 1, the spacer pin 2 is fastened in the annular groove 34 on the screw head 33, and the positioning plane 5 is arranged outside the central axis 4. The utility model not only enhances the symmetrical jaw facial shape after stretching osteogenesis but also has lower price than imported products.
Description
Technical field
This utility model is a kind of medical apparatus and instruments that can two-way prolongation jawbone, can be used for short and small odd-shaped the rescuing of maxillofacial bone.Belong to the technical field that medical apparatus and instruments is made.
Background technology
The distraction osteogenesis technology is to correct the short and small odd-shaped a kind of new method of bone in recent years, this The Application of Technology makes that rescued the short and small odd-shaped complicated surgical operation of bone becomes simple in the past, and reduced operation risk significantly, one of key problem in technology of distraction osteogenesis is a bone stretching device, especially correct in the prolongation of jawbone, the stretching device is had higher requirement.In clinical practice is used, find, the prolongation of short and small jawbone single direction is difficult to reach the requirement of the short and small abnormity orthopedics of jawbone often, and multidirectional jawbone prolongs the deformity that can correct short and small jawbone more.The invention of two-way jawbone stretching device can solve the prolongation of jawbone on both direction, significantly improves the short and small odd-shaped rectification of jawbone.At present, still unparalleled invention report to jawbone stretching device.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of short and small odd-shaped rectification of face jawbone that is used for, and has the vertical twin shaft jawbone stretching device that vertical twin shaft prolongs function.
Technical scheme: vertical twin shaft jawbone stretching device of the present utility model, formed by device for transverse traction and longitudinal towing mechanism, the mutual square crossing of device for transverse traction and longitudinal towing mechanism fixes, wherein each traction apparatus is by overcoat, spacer pin, screw rod, axis, plane of orientation is formed, the female thread that screw flight partly is arranged in axis matches, one end of overcoat is enclosed within outside the screw rod head of screw rod, the other end of overcoat is enclosed within outside the axis, be provided with spacer pin on the coat, spacer pin is stuck in the cannelure on the screw rod head, and plane of orientation is located at the outer end of axis.
This utility model is to use like this, suffering from the short and small odd-shaped patient of upper jaw bone or mandibular bone, the jawbone that need are prolonged designs the osteotomy line, block or partly block the jawbone that is extended with electric bone saw, the standing part of stretching device is followed closely the both sides that are individually fixed in the osteotomy line with titanium, rotation prolongs knob, prolong 1mm every day, determine the distance that both direction prolongs according to the corrigent position of need, satisfied until profile, prolong end and got except that the stretching device in back 3 months.
Beneficial effect: in causing the short and small odd-shaped common disease of jawbone, the incidence rate of congenital harelip is 1: 700, and the sickness rate of the short and small disease of congenital demifacet is 1: 7000.Therefore, the short and small odd-shaped number of patients of jawbone is very large in the numerous population of China, this class congenital malformation has not only been destroyed facial profile, and usually can cause the serious mental maladjustment of infant, also brings very big mental pressure and economic pressures to family.At present, each price of stretching device of import is up to ten thousand yuan of 1-2, and the unidirectional prolongation function of tool only.This utility model not only can improve jaw behind the distraction osteogenesis and the symmetric profile of portion, and price is lower than imported product.
Description of drawings
Fig. 1 is a population structure sketch map of the present utility model.
Fig. 2 be among Fig. 1 A-A to the sectional structure sketch map.
Overcoat 1, spacer pin 2, screw rod 3, screw slot 31, screw thread 32, screw rod head 33, cannelure 34, axis 4, plane of orientation 5 are wherein arranged.
The specific embodiment
Vertical twin shaft jawbone stretching device of the present utility model is made up of device for transverse traction and longitudinal towing mechanism, all materials all adopt rustless steel to make, the mutual square crossing of device for transverse traction and longitudinal towing mechanism fixes, wherein each traction apparatus is by overcoat 1, spacer pin 2, screw rod 3, axis 4, plane of orientation 5 is formed, the female thread that screw thread 32 parts of screw rod 3 are arranged in axis 4 matches, one end of overcoat 1 is enclosed within outside the screw rod head 33 of screw rod 3, the other end of overcoat 1 is enclosed within outside the axis 4, on overcoat 1, be provided with spacer pin 2, spacer pin 2 is stuck in the cannelure 34 on the screw rod head 33, and plane of orientation 5 is located at the outer end of axis 4.During use plane of orientation 5 usefulness titaniums nail is individually fixed in the both sides of osteotomy line,, reaches the effect that changes both direction prolongation distance by adjusting screw slot 31 rotary screws 3.
