The utility model discloses a bone conduction board is cut to tooth -borne type piecemeal chin shaping art takes one's place based on the tooth, and intraoperative localization is accurate, cuts the difficult drift of bone scope and osteotomy position, and can guide the saw bit to cut the angle of bone to make the operation more accurate, can guide complicated chin shaping operation.
Description
Technical field
This utility model relates to craniofacial orthopedics technical field of medical instruments, is specifically related to a kind of tooth-borne type piecemeal chin urethroptasty osteotomy guide plate.
Background technology
Chin urethroptasty is the size and location by changing chin portion bone piece, changes patient's chin portion form, corrects chin portion deformity, increases basifacial attractive in appearance. In traditional operation, operative doctor needs to rely on the clinical experience of self to determine osteotomy line position in art, to avoid damage to inferior alveolar nerve and mental nerve, completes osteotomy.
Art often exists an osteotomy too much, patient is caused unnecessary many degree damages; Or osteotomy is inadequate, it is necessary to repeated multiple times grind, operating time and intraoperative hemorrhage can be increased. Then, the bone piece cut down dominated by hand, by the measurement in art and assessment, is moved and puts on desirable locus. So, for complicated chin molding operation, often more difficult in art, carry out osteotomy and bone piece location exactly, simultaneously for rotation also more difficult the control of chin portion bone piece.
Utility model content
The purpose of this utility model is to provide a kind of tooth-borne type piecemeal chin urethroptasty osteotomy guide plate, it is to avoid often there is an osteotomy in art too much, and patient causes unnecessary many degree damages; Or osteotomy is inadequate, it is necessary to repeated multiple times grind, increase the problem such as operating time and intraoperative hemorrhage.
According to an aspect of the present utility model, it is provided that a kind of tooth-borne type piecemeal chin urethroptasty osteotomy guide plate, including: tooth support sector, connecting portion and fixed part, one end of described connecting portion is connected with described tooth support sector, and the other end is connected with described fixed part; Described tooth support sector is provided with the cell body matched with mandibular anterior teeth denture; The two ends of described fixed part have the osteotomy groove that can hold electric saw blade, and described osteotomy groove coincide consistent with osteotomy line position, osteotomy amount; The two ends of described fixed part are also provided with multiple fixing hole; The both sides of the junction of described connecting portion and described fixed part are provided with boss.
Wherein, in above-mentioned tooth-borne type piecemeal chin urethroptasty osteotomy guide plate, the two ends of described fixed part are provided with three fixing holes, and the distribution mode of three described fixing hole triangularities is arranged.
Wherein, in above-mentioned tooth-borne type piecemeal chin urethroptasty osteotomy guide plate, each described fixing hole is the circular hole that diameter is 2mm.
Wherein, in above-mentioned tooth-borne type piecemeal chin urethroptasty osteotomy guide plate, described tooth support sector, described connecting portion and described fixed part form as one formula structure.
Wherein, in above-mentioned tooth-borne type piecemeal chin urethroptasty osteotomy guide plate, described osteotomy guide plate is made up of resin material.
A kind of tooth-borne type piecemeal chin urethroptasty osteotomy guide plate of the present utility model has plurality of advantages, for instance:
(1) in place based on tooth, Intraoperative position is accurate, and osteotomy scope and osteotomy site not easily drift about;
(2) it is provided with osteotomy groove, and the resin material adopted has certain thickness, the angle of bootable saw blade osteotomy, so that operation is more accurate, it is possible to instruct complicated chin molding operation.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention and with reference to accompanying drawing, this utility model is further described. It should be understood that these descriptions are illustrative of, and it is not intended to limit scope of the present utility model. Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
Fig. 1 is the structural representation of the tooth-borne type piecemeal chin urethroptasty osteotomy guide plate of this utility model embodiment; The structural representation of Tu2Shi Tu1 dens in dente support sector.
The structure of the tooth-borne type piecemeal chin urethroptasty osteotomy guide plate of this utility model embodiment as depicted in figs. 1 and 2, including tooth support sector 1, connecting portion 2 and fixed part 3. Wherein, one end of connecting portion 2 is connected with tooth support sector 1, and the other end of connecting portion 2 is connected with fixed part 3, and tooth support sector 1, connecting portion 2 and fixed part 3 form as one formula structure, and the osteotomy guide plate of integral type is made up of resin material.
Specifically, tooth support sector 1 is provided with the cell body 4 matched with mandibular anterior teeth denture, can position based on tooth. The two ends of fixed part 3 have the osteotomy groove 5 that can hold electric saw blade, osteotomy groove 5 coincide consistent with osteotomy line position, osteotomy amount, and resin material has certain thickness, the angle of bootable saw blade osteotomy, so that operation is more accurate, it is possible to instruct complicated chin molding operation. The two ends of fixed part 3 are also provided with multiple fixing hole 6, for instance three, and each fixing hole 6 is the circular hole that diameter is 2mm, and the distribution mode of these three fixing hole 6 triangularities is arranged, and improves fixing intensity.
