Abstract
The utility model discloses a shaping of titanium alloy chin cuts bone conduction board, include: cut the bone conduction edition of books body, cut the arcwall face of inboard formation with the bone closed -up surface laminating of chin portion of the bone conduction edition of books body, cut the both ends of the bone conduction edition of books body and all open the osteotomy slot that can hold electric saw blade, osteotomy slot and osteotomy line position, osteotomy amount coincide unanimously, the both ends of cutting the bone conduction edition of books body still all are provided with three fixed orifices, and are three the distribution mode that the fixed orifices becomes triangle -shaped sets up. The utility model discloses a shaping of titanium alloy chin cuts bone conduction board can avoid in the art chin portion bone coarse problem of taking one's place, simultaneously no longer need be to finished product titanium bone plate turn system, and the osteotomy slot of setting can guide the angle of saw bit section bone to make the operation more accurate, can guide the bone osteotomy surgery of chin portion.
Description
Technical field
This utility model relates to craniofacial orthopedics technical field of medical instruments, is specifically related to a kind of titanium alloy chin molding 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 titanium alloy chin molding osteotomy guide plate, can avoid bone coarse problem in place in chin portion in art, it is possible to avoid often there is an osteotomy in art too much, and patient causes unnecessary many degree damages.
According to an aspect of the present utility model, it is provided that a kind of titanium alloy chin molding osteotomy guide plate, including: osteotomy guide plate body, the inner side of described osteotomy guide plate body forms the arcwall face fitted tightly with chin portion bone surface; All have the osteotomy groove that can hold electric saw blade at the two ends of described osteotomy guide plate body, described osteotomy groove coincide consistent with osteotomy line position, osteotomy amount; Also being provided with three fixing holes at the two ends of described osteotomy guide plate body, the distribution mode of three described fixing hole triangularities is arranged.
Wherein, in above-mentioned titanium alloy chin molding osteotomy guide plate, three fixing holes being positioned at each end of described osteotomy guide plate body divide two groups of both sides being arranged on osteotomy groove, and one group is a fixing hole, and another group is two fixing holes.
Wherein, in above-mentioned titanium alloy chin molding osteotomy guide plate, each described fixing hole is the circular hole that diameter is 2mm.
Wherein, in above-mentioned titanium alloy chin molding osteotomy guide plate, described osteotomy guide plate body is titanium alloy material.
A kind of titanium alloy chin molding osteotomy guide plate of the present utility model, bone coarse problem in place in chin portion in art can be avoided, it is no longer necessary to finished product titanium bone plate is bent simultaneously, and the angle of the bootable saw blade osteotomy of osteotomy groove arranged, so that operation is more accurate, it is possible to instruct chin portion bone bone-culting operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the titanium alloy chin molding osteotomy guide plate of this utility model embodiment;
Fig. 2 is the front view of Fig. 1;
Wherein:
1 is osteotomy guide plate body; 2 is osteotomy groove; 3 is fixing hole.
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.
The structure of the titanium alloy chin molding osteotomy guide plate of this utility model embodiment includes as depicted in figs. 1 and 2: osteotomy guide plate body 1, and osteotomy guide plate body 1 is titanium alloy material, and the inner side of this osteotomy guide plate body 1 forms the arcwall face fitted tightly with chin portion bone surface.
In the present embodiment, all have the osteotomy groove 2 that can hold electric saw blade at the two ends of osteotomy guide plate body 1, this osteotomy groove 2 coincide consistent with osteotomy line position, osteotomy amount, the angle of bootable saw blade osteotomy, so that operation is more accurate, it is possible to instruct chin portion bone bone-culting operation.
In the present embodiment, being also provided with three fixing holes 3 at the two ends of osteotomy guide plate body 1, each fixing hole 3 is the circular hole that diameter is 2mm, and the distribution mode of these three fixing hole 3 triangularities is arranged, and improves fixing intensity. Here, three fixing holes 3 points two groups being positioned at each end of osteotomy guide plate body 1 are arranged on the both sides of osteotomy groove 2, and one group is a fixing hole 3, and another group is two fixing holes 3.
As mentioned above, a kind of titanium alloy chin molding osteotomy guide plate of the present utility model, bone coarse problem in place in chin portion in art can be avoided, it is no longer necessary to finished product titanium bone plate is bent simultaneously, and the angle of the bootable saw blade osteotomy of osteotomy groove arranged, so that operation is more accurate, it is possible to instruct chin portion bone bone-culting operation.
It should be appreciated that above-mentioned detailed description of the invention of the present utility model is used only for exemplary illustration or explains principle of the present utility model, and do not constitute restriction of the present utility model. Therefore, any amendment of making when not necessarily departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., should be included within protection domain of the present utility model. Additionally, this utility model claims be intended to fall in the equivalents on scope and border or this scope and border whole change and modifications example.
