Abstract
The utility model relates to an alveolar ridge three-dimensional osteogenic retractor which can solve the problem of three-dimensional osteogen one time and simultaneously heighten and broaden the atrophic alveolar ridge, thereby greatly shortening the surgery time and reducing the surgery risks. The alveolar ridge three-dimensional osteogenic retractor of the utility model comprises a horizontal retractor and a vertical retractor, wherein the horizontal retractor is connected with the vertical retractor vertically, the vertical retractor is equipped with an upper retaining arm fixed with an osteotomy block and a lower retaining arm fixed with a mandible base, the horizontal retractor and the vertical retractor are separately provided with a horizontal traction screw and a vertical traction screw, and the horizontal traction screw revolves into the osteotomy block through a screw hole arranged at the retaining arm on the vertical retractor and an inner screw thread of a retaining screw.
Description
One, technical field:
This utility model relates to a kind of medical department of stomatology apparatus, especially relates to the three-dimensional one-tenth of a kind of alveolar ridge bone tractor, the patient that it is used for carrying out the artificial tooth reparation and need increases the broadening alveolar bone simultaneously.
Two, background technology:
The distraction osteogenesis technology is to treat the damaged a kind of new method of oral and maxillofacial surgery bone at present, also is the focus of studying both at home and abroad at present.But existing internal traction device can only be done the bone amplification of two dimension because design is limited, can't solve simultaneously increase, the problem of broadening atrophy alveolar ridge, operating time is prolonged, operation risk strengthens.
Three, utility model content:
This utility model is in order to solve the weak point in the above-mentioned background technology, provide that a kind of alveolar ridge is three-dimensional to become bone tractor, the problem that it can the three-dimensional skeletonization of disposable solution can increase, broadening atrophy alveolar ridge simultaneously, shorten operating time greatly, reduced the risk of operation.
For achieving the above object, the technical solution adopted in the utility model is:
The three-dimensional one-tenth of a kind of alveolar ridge bone tractor, its special character is: comprise horizontally tracting device and vertical distraction device, the horizontally tracting device is connected with the vertical distraction device is vertical, and the vertical distraction device is provided with respectively last retention arm and the following retention arm that fixes with osteotomy piece, mandibular bone base portion.
The screw on the retention arm is connected with the vertical distraction device above-mentioned horizontally tracting device on the vertical distraction device by being located at, and passes the osteotomy piece by the retaining screw that contains internal and external threads.
Be respectively equipped with horizontally tracting screw and vertical distraction screw on above-mentioned horizontally tracting device and the vertical distraction device, the screw on the retention arm also screws in the osteotomy piece by the female thread of retaining screw the horizontally tracting screw on the vertical distraction device by being located at.
Above-mentioned horizontally tracting screw one end is provided with the screw that stops that has female thread.
Above-mentioned traction screw head is a spanner, and the spanner width is wider than traction screw width, and traction screw end is divided into the terminal and blunt type end of circle of sharp-pointed type.
Above-mentioned retaining screw is hollow and has and draw the supporting female thread of screw external screw thread that the retaining screw head is a spanner.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
This utility model has been realized moving when the osteotomy piece is on vertical, horizontal both direction, can do the amplification of three-dimensional bone, designs ingeniously, and volume is small and exquisite, and is easy to operate, effectively shortened treatment time.

Among the figure, the 1-alveolar bone, 2-osteotomy line, 3-vertical distraction screw, the 4-retaining screw, 5-stops screw, 6-horizontally tracting screw, retention arm under the 7-, the last retention arm of 8-.
Five, the specific embodiment:
Referring to Fig. 1 and Fig. 2, this utility model comprises horizontally tracting device and vertical distraction device, the vertical distraction device is provided with respectively and the osteotomy piece, last retention arm 8 and following retention arm 7 that the mandibular bone base portion fixes, have a plurality of screws on last retention arm 8 and the following retention arm 7, be respectively equipped with horizontally tracting screw 6 and vertical distraction screw 3 on horizontally tracting device and the vertical distraction device, screw on the retention arm 8 also screws in the osteotomy piece by the female thread of retaining screw 4 horizontally tracting screw 6 on the vertical distraction device by opening, vertical distraction screw 3 also screws in the osteotomy piece, the retaining screw that has an internal and external threads is by in the screw-in of the screw on last retention arm 8 and the following retention arm 7 osteotomy piece, horizontally tracting screw 6 one ends be provided with have a female thread stop screw 5.Referring to Fig. 3, the traction screw head is a spanner, and the spanner width is wider than traction screw width, and traction screw end is divided into the terminal and blunt type end of circle of sharp-pointed type, and length is 2 millimeters, and the diameter of thread is less than 2 millimeters, 0.4 millimeter/circle of pitch.Referring to Fig. 4, retaining screw has internal and external threads, and head is a spanner, and hollow also has and draws the supporting female thread of screw, and length is 3 millimeters～5 millimeters, and height is less than 1.5 millimeters.Referring to Fig. 5, stop that screw is divided into 2 millimeters, 3 millimeters and 5 millimeters three kinds, female thread is arranged, no external screw thread, no spanner, specification is identical with retaining screw.
During actual the use, retaining screw on the vertical distraction screw 3 is screwed in the osteotomy piece, screw on the retention arm 8 also screws in the osteotomy piece by the female thread of retaining screw 4 horizontally tracting screw 6 on the vertical distraction device by opening, by rotation vertical distraction screw 3 and horizontally tracting screw 6, realize the osteotomy piece simultaneously upward, the place ahead motion, thereby realize the three-dimensional amplification of alveolar bone.
