Abstract
A measuring instrument for positioning mandibular angle osteotomy relates to a positioning device for mandibular angle osteotomy reshaping and solves the problem of inaccurate positioning of an osteotomy line in the mandibular angle osteotomy reshaping. The measuring instrument comprises a scale with graduations, a positioning snap ring is fixed at the tail end of the scale, a positioning slide bar is sleeved on the scale, a positioning pointer is fixed at the end, which is close to the positioning snap ring, of the positioning slide bar, and is perpendicular to the positioning slide bar, a fixing bolt is arranged at the other end of the positioning slide bar, and the positioning slide bar is fixed on the scale through the fixing bolt. By adopting the measuring instrument, the osteotomy line designed before an operation can be better reproduced on mandible face in oral cavity, so as to guarantee the symmetry of osteotomy and to ensure that two sides of the mandible are symmetrical after operations; meanwhile, the positioning time for the operation is greatly shortened, the structure is simple, and the operation is convenient.
Description
Technical field
This utility model relates to the positioner that a kind of mandibular angle bone cutting shaping is used, specifically mandibular angle bone cutting location survey device.
Background technology
The mandibular angle bone cutting shaping is through amputation angle of mandible and part ascending branch and body sclerotin, thus reduction face lower width and reach the arcual flow process profile in side, and the square face women roomy for basifacial can obviously improve basifacial ratio and outward appearance.Approach is operated in the at present general through port of mandibular angle bone cutting shaping; Operation can avoid the outside to leave over cicatrix in mouthful; But in mouthful the operating position cry dark, the visual field is narrow and small, it is substantially parallel with the operating field plane to cut bone line plane, gives accurately to locate a section bone tape in the art and come great difficulty.The experience that relies on the patient often and technology be the judgement osteotomy site directly, can not guarantee that symmetry cuts the symmetry of bone and postoperative bilateral.
The utility model content
The purpose of this utility model is to provide a kind of mandibular angle bone cutting location survey device, and the shaping of solution mandibular angle bone cutting cuts the bone line and locatees inaccurate problem.
This utility model solves the technical scheme that its technical problem adopted: mandibular angle bone cutting location survey device; It is characterized in that; Comprise and be with graduated scale, the end of scale is fixed with the location snap ring, is with a location slide bar on the scale; Locating slide rod is fixed with a positioning pointer near an end of location snap ring, and positioning pointer is vertical with locating slide rod; The other end of described locating slide rod also is provided with set bolt, is fixed on the scale through set bolt; Described location snap ring is an arc, matches with the radian of angle of mandible.
The beneficial effect of this utility model is: design a section bone line before copying art on the interior mandibular bone surface of bone of better and mouth, can guarantee the symmetry of section bone and postoperative bilateral, the while can shorten positioning time in the operation greatly, and is simple in structure easy to operate.
Description of drawings
Fig. 1 is the front view of this utility model,
Fig. 2 is the left view of this utility model.
Among the figure: 1 scale, 2 location snap rings, 3 locating slide rods, 4 positioning pointers, 5 bolts
The specific embodiment
Like Fig. 1, shown in Figure 2, mandibular angle bone cutting location survey device; Comprise and be with graduated scale 1, the end of scale 1 to be fixed with location snap ring 2, be with a location slide bar 3 on the scale 1; Locating slide rod 3 is fixed with a positioning pointer 4 near an end of location snap ring 2, and positioning pointer 4 is vertical with locating slide rod 3; The other end of described locating slide rod 3 also is provided with set bolt 5, is fixed on the scale 1 through set bolt 5; Described location snap ring 2 is an arc, matches with the radian of angle of mandible.
During use, will locate snap ring 2 and place the angle of mandible place, the cambered surface of location snap ring 2 just interlocks with lower border of the mandible; Scale 1 end is a witness marker with the back zone of grinding one's teeth in sleep; Running fix slide bar 3 makes the positioning pointer 4 of locating slide rod 3 ends refer to section bone camber line of the preceding labelling of Rhizoma Atractylodis Macrocephalae, and the bolt 5 of screwing makes locating slide rod 3 fixing; Prevent to produce in the process of taking again and slide, accuracy is measured in influence.After moving to this measuring device in the mouth then, will locate snap ring 2 and place angle of mandible sclerotin place, confirm to decide a little on the angle of mandibles that adopting uses the same method confirms some anchor points, and each point is connected to form the ruling camber line according to positioning pointer 4, and accomplish to locate and cut the bone line.
