Abstract
The invention discloses a built-in shaping and distraction osteogenesis device. The built-in shaping and distraction osteogenesis device comprises a shaping plate used for a section needing distraction osteogenesis, wherein the shaping plate is provided with a connection threaded hole; a connection screw penetrates through the connection threaded hole and the distraction osteogenesis device to integrally connect the shaping plate with the distraction osteogenesis device; the distraction osteogenesis device has two movable wings; the other side wing of the distraction osteogenesis device is provided with a long slotted hole; a bidirectional lead screw is arranged in the long slotted hole; and the two movable wings are connected to the bidirectional lead screw. The two movable wings can move oppositely when the bidirectional lead screw rotates; and one end of the bidirectional lead screw is also connected to a universal joint. Such the structure avoids the disadvantages that operation difficulty, operative wound and operation time are added due to the accomplishment of the distraction osteogenesis through two operations; and the built-in type integral type distraction osteogenesis device is not only a built-in type distraction osteogenesis device, but also can be used for carrying out shaping and distraction osteogenesis for the lower jawbone through one operation.
Description
Technical field
The invention belongs to mandibular bone integer distraction device technical field, be specifically related to a kind of built-in integer distraction osteogenesis device, the operative treatment being particularly applied to Maxillary region micrognathia also can complete the Oral and Maxillofacial Surgery instrument field of mandibular bone molding and distraction osteogenesis in once performing the operation simultaneously.
Background technology
Current skeletonization and the application of shaped device are fixed by the special built-in dieplate of the bone block broken, and waits its gap Adhesion formation of breaking overall, then remove dieplate and carry out integer and complete; Distraction osteogenesis is after being cut by bone, applies special built-in traction apparatus and carries out slow tractive, make to form new bone in osteotomy gap thus reach skeleton extend object.Forming technique and distraction osteogenesis are all the most often applied to prolongation mandibular bone, treat the lower jaw abnormality that all kinds of reason causes.
Such skeletonization and shaped device first must do molding operation when lower jaw deformity treatment, and then do distraction osteogenesis, and performed the operation so at twice, this adds operating difficulty, operation wound and operating time undoubtedly.And also there is no the device that simultaneously can be applicable to molding and distraction osteogenesis now.
Summary of the invention
Object of the present invention provides a kind of built-in integer distraction osteogenesis device, comprise the dieplate for needing distraction osteogenesis section, described dieplate is provided with connecting thread hole, dieplate and distraction device integration are linked together through connecting thread hole and distraction device with attachment screw, the movable wing quantity of distraction device is two, the flank of distraction device is provided with long slot bore in addition, two-way leading screw is provided with in long slot bore, and described two movable wings are connected with two-way leading screw, such two movable wings can the adverse movement when two-way screw turns, one end of two-way leading screw is also connected with universal joint.Such structure avoids has performed the operation at twice and has added the defect of operating difficulty, operation wound and operating time, and this built-in integer distraction osteogenesis device is not only internally-arranged type, and this device can be used to implement mandibular bone integer and distraction osteogenesis by once performing the operation simultaneously.
In order to overcome deficiency of the prior art, the invention provides a kind of solution of built-in integer distraction osteogenesis device, specific as follows:
A kind of built-in integer distraction osteogenesis device, comprise the dieplate 1 for needing distraction osteogenesis section, described dieplate 1 is provided with connecting thread hole, dieplate 1 and distraction device 2 integration are linked together through connecting thread hole and distraction device 2 with attachment screw 3, movable wing 7 quantity of distraction device 2 is two, the flank of distraction device 2 is provided with long slot bore 4 in addition, two-way leading screw 5 is provided with in long slot bore 4, and described two movable wings 7 are connected with two-way leading screw 5, such two movable wings 7 can the adverse movement when two-way leading screw 5 rotates, one end of two-way leading screw 5 is also connected with universal joint 6.
Described distraction device 2 is Distraction Apparatus.
The mode that the integration of described dieplate 1 and distraction device 2 is connected can also soldered or mosaic mode substitute.
Apply such scheme of the present invention, dieplate and distraction device are linked together, make dieplate both can carry out integer to the bone block broken, can use as the fixed-wing of distraction device again, distraction device only establishes two movable wings, once can design two place's osteotomy lines during operation, realize once performing the operation, two place's distraction osteogenesis.The flank of particularly described distraction device 2 is provided with long slot bore 4, two-way leading screw 5 is provided with in long slot bore 4, and described two movable wings 7 are connected with two-way leading screw 5, such two movable wings 7 can the adverse movement when two-way leading screw 5 rotates, and one end of two-way leading screw 5 is also connected with universal joint 6.Such mode when universal joint 6 drives two-way leading screw 5 to move, can directly can drive the adverse movement of two movable wings 7, and such mode can allow the time shorten half of distraction osteogenesis.
Accompanying drawing explanation
Figure l is front cross-sectional structural representation of the present invention.
Fig. 2 is side, sectional structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, summary of the invention is described further:
Shown in seeing figures.1.and.2, a kind of built-in integer distraction osteogenesis device, comprise the dieplate 1 for needing distraction osteogenesis section, described dieplate 1 is provided with connecting thread hole, dieplate 1 and distraction device 2 integration are linked together through connecting thread hole and distraction device 2 with attachment screw 3, movable wing 7 quantity of distraction device 2 is two, the flank of distraction device 2 is provided with long slot bore 4 in addition, two-way leading screw 5 is provided with in long slot bore 4, and described two movable wings 7 are connected with two-way leading screw 5, such two movable wings 7 can the adverse movement when two-way leading screw 5 rotates, one end of two-way leading screw 5 is also connected with universal joint 6.Described distraction device 2 is Distraction Apparatus.The mode that the integration of described dieplate 1 and distraction device 2 is connected can also soldered or mosaic mode substitute.
Apply such scheme of the present invention, dieplate and distraction device are linked together, make dieplate both can carry out integer to the bone block broken, can use as the fixed-wing of distraction device again, distraction device only establishes two movable wings, once can design two place's osteotomy lines during operation, realize once performing the operation, two place's distraction osteogenesis.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to technical spirit of the present invention, within the spirit and principles in the present invention, to any simple amendment that above embodiment is done, equivalent replacement and improvement etc., within the protection domain all still belonging to technical solution of the present invention.
