Abstract
The utility model provides a lower jaw angle location baffle which characterized in that: which comprises a body, the internal surface of body is identical with lower jaw angle outside surface, notch, lower jaw angle and inferior maxilla ascending branch trailing edge form unanimity before the edge of body and the lower jaw angle lower edge angle are equipped with two guide posts that are parallel to each other in the middle -end of body, the guide post runs through in the body, and respectively there is a centre bore centre of every guide post, inserts the ke shi needle in the centre bore, assists the location of keshi needle, the both ends of body are equipped with and are used for the resting guide in the inferior maxilla and run through two fixed columns of body, respectively have a nail hole in the middle of every fixed column, and the nail inserts set screw in the hole, fix the baffle on the inferior maxilla, the utility model discloses an advantage: this lower jaw angle location baffle simple structure, convenient to use can effectively reduce the risk and the degree of difficulty of operation, has certain practicality.
Description
Technical field
This utility model relates to automation field, particularly a kind of angle of mandible positioning guide plate.
Background technology
Condyle fracture of mandibles can cause the dysfunctions such as TMJ Pain, ankylosis, limitation of mouth opening, now just need to carry out the operation of condyle fracture of mandibles replacement and fixation, Kirschner wire internal fixation is a kind of operation method that treatment condyle fracture of mandibles is conventional, and the factor of most important impact operation success or failure is exactly the direction that pierces, the particularly Kirschner wire direction in Mandibular Rumas of Kirschner wire in Kirschner wire internal fixation.Because mandibular bone cortical bone is thicker, the space of medullary cavity is less, shape is irregular again; And in medullary cavity, have inferior alveolar nerve vascular bundle, once damage can produce numbness of lower lip, the severe complication such as hemorrhage, the orientation of placing to Kirschner wire in art causes certain difficulty.Moreover, the placement direction of Kirschner wire mistake causes the prominent difficulty that resets of the condyle of fracture, and therefore, the determination of Kirschner wire placement direction and control are exactly the key point of operation success or failure.
At present, most of positioner utilizes inferior border of mandible and the condylar fracture broken ends of fractured bone straight line that reconnaissance is formed respectively to position, this kind of locate mode structure is comparatively complicated, and the limitation of apparatus model cannot solve the problem of each condylar fracture individuality, adopt the traveling cannot looking at medullary cavity and inferior alveolar nerve vascular bundle in mandibular ramus during the method straight, more easily occur that location is inaccurate.And the Rotation that free condyle cannot be avoided during single Kirschner wire fixation condyle fracture of mandibles prominent.The operation which results in doctor's operating process is unsuccessful, therefore, needs a kind of positioner being more adapted to apply Kirschner wire treatment condyle fracture of mandibles patient.
Summary of the invention
The purpose of this utility model is to solve above-mentioned Problems existing, and spy provides a kind of angle of mandible positioning guide plate.
This utility model provides a kind of angle of mandible positioning guide plate, it is characterized in that: comprise body 1, inner surface and the angle of mandible outer surface of described body 1 match, the edge of described body 1 and lower border of the mandible antegonial notch, angle of mandible and Mandibular Rumas trailing edge form consistent, two leads be parallel to each other 2 are provided with in the middle-end of body 1, described lead 2 is through body 1, respectively there is a centre bore 3 centre of each lead 2, Kirschner wire is inserted in centre bore 3, come the location of auxiliary Kirschner wire, the two ends of described body 1 are provided with runs through two fixed legs 4 of body 1 for resting guide in mandibular bone, a nail 5 is respectively had in the middle of each fixed leg 4, hold-down screw is inserted in nail 5, guide plate is fixed on mandibular bone.
As preferred technical scheme, the altitude range of described lead 2 is (1-10) cm, and the diameter range of described centre bore 3 is (0.5-2) mm.
As preferred technical scheme, the altitude range of described fixed leg 4 is (0.2-2) cm, and the diameter range of described nail 5 is (0.5-2) mm, and the axis direction of described nail 5 avoids inferior alveolar nerve vascular bundle.
Advantage of the present utility model:
Angle of mandible positioning guide plate structure described in the utility model is simple, easy to use, effectively can reduce risk and the difficulty of operation, have certain practicality.
