Abstract
The utility model discloses a tooth -borne type's chin shaping cuts bone conduction board, it includes to cut the bone conduction board: tooth support part, connecting portion and fixed part, the one end of connecting portion with tooth support part connects, the other end of connecting portion with the fixed part is connected, be provided with on the tooth support part with mandibular anterior teeth dental arch assorted cell body, the osteotomy slot that can hold electric saw blade is opened respectively at the both ends of fixed part, osteotomy slot and osteotomy line position, osteotomy amount coincide unanimously, the both ends of fixed part still all are provided with a plurality of fixed orificess. The utility model discloses a tooth -borne type's chin shaping cuts bone conduction board 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
The utility model relates to craniofacial orthopedics technical field of medical instruments, is specifically related to the shaping osteotomy guide plate of the supported chin of a kind of tooth.
Background technology
Chin urethroptasty is the size by changing chin portion bone block and position, changes patient's chin portion form, corrects chin portion deformity, increases bottom, face 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 nervus alverlaris and nervus mentalis, completes osteotomy.
Art often exists an osteotomy too much, patient is caused unnecessary many degree damage; Or osteotomy is inadequate, it is necessary to repeated multiple times grind, operating time and intraoperative hemorrhage can be increased. Then, the bone block cut down dominated by hand, by measuring and evaluating in art, is moved and is put on desirable locus. Like this, for the shaping operation of chin of complexity, often more difficult accurately carrying out osteotomy and bone block location in art, simultaneously rotation for chin portion bone block is also more difficult control.
Practical novel content
The purpose of this utility model is to provide the shaping osteotomy guide plate of the supported chin of a kind of tooth, avoids often there is an osteotomy in art too much, and patient causes unnecessary many degree damage; 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, the shaping osteotomy guide plate of the chin providing a kind of tooth supported, described osteotomy guide plate comprises: tooth support section, connection section and fixing portion, and one end of described connection section is connected with described tooth support section, and the other end of described connection section is connected with described fixing portion; Described tooth support section is provided with the groove body arranging with lower jaw anterior teeth and mating mutually; The two ends in described fixing portion 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 in described fixing portion are also provided with multiple fixed orifices.
Wherein, in the shaping osteotomy guide plate of the chin that above-mentioned tooth is supported, the two ends in described fixing portion are provided with four fixed orificess, and four described fixed orificess are divided into the both sides that two groups are separately positioned on described osteotomy groove.
Wherein, in the shaping osteotomy guide plate of the chin that above-mentioned tooth is supported, fixed orifices described in each is the circular hole that diameter is 2mm.
Wherein, in the shaping osteotomy guide plate of the chin that above-mentioned tooth is supported, described tooth support section, described connection section and described fixing portion form as one formula structure.
Wherein, in the shaping osteotomy guide plate of the chin that above-mentioned tooth is supported, the arc that described fixing portion is formed as with chin portion bone surface fits tightly, the two ends of described arc are provided with anti-skidding back-off.
The supported shaping osteotomy guide plate of chin of a kind of tooth of the present utility model has plurality of advantages, such as:
(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, thus makes operation more accurate, it is possible to instruct the complicated shaping operation of chin.
Accompanying drawing explanation
Fig. 1 is the front view of the supported shaping osteotomy guide plate of chin of the tooth of the utility model embodiment;
Fig. 2 is the left view of the supported shaping osteotomy guide plate of chin of the tooth of the utility model embodiment;
Wherein:
1 is tooth support section; 2 is connection section; 3 is fixing portion; 4 is groove body; 5 is osteotomy groove; 6 is fixed orifices; 7 is arc.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and with reference to accompanying drawing, the utility model is further described. It is to be understood that these describe just exemplary, and do not really want to limit scope of the present utility model. In addition, in the following description, eliminate the description to known features and technology, unnecessarily obscure concept of the present utility model to avoid.
The structure of the shaping osteotomy guide plate of chin that the tooth of the utility model embodiment is supported as depicted in figs. 1 and 2, comprising: tooth support section 1, connection section 2 and fixing portion 3. Wherein, one end of connection section 2 is connected with tooth support section 1, and the other end of connection section 2 is connected with fixing portion 3, and tooth support section 1, connection section 2 and fixing portion 3 form as one formula structure, and the osteotomy guide plate of integral type is made up of resin material.
Specifically, tooth support section 1 is provided with the groove body 4 arranging with lower jaw anterior teeth and mating mutually, can locate based on tooth. The two ends in fixing portion 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, thus make operation more accurate, it is possible to instruct the complicated shaping operation of chin. The two ends in fixing portion 3 are also provided with multiple fixed orifices 6, such as four, each fixed orifices 6 is the circular hole that diameter is 2mm, and four fixed orificess 6 are divided into the both sides that two groups are separately positioned on osteotomy groove 5, it is to increase constant intensity.
Preferably, in the present embodiment, this arc 7 that fixing portion 3 is formed as with chin portion bone surface fits tightly, the two ends of arc 7 are provided with anti-skidding back-off, to improve the fix tightly solidity of osteotomy guide plate, prevent osteotomy scope and osteotomy site drift.
As mentioned above, it is necessary, the shaping osteotomy guide plate of chin that a kind of tooth of the present utility model is supported, in place based on tooth, Intraoperative position is accurate, and osteotomy scope and osteotomy site not easily drift about, and the angle of bootable saw blade osteotomy, thus make operation more accurate, it is possible to instruct the complicated shaping operation of chin.
