Description
Technical field
This utility model relates to craniofacial orthopedics technical field of medical instruments, is specifically related to a kind of mandibular distraction osteogenesis surgical guide.
Background technology
Mandibular distraction osteogenesis operation is the art formula correcting deformitas maxillaris that a kind of clinic is the most frequently used, traditional art formula is that operative doctor is after blocking mandibular bone, bone section is moved to the position designed, then the titanium alloy blade plate adopting finished product is fixed, thus reaching to improve the purpose of the skeleton deformity of patient. Although the titanium plate of finished product has plurality of specifications in the market, but owing to mandibular bone is the irregular bone of a kind of morphosis complexity, therefore in operation fixation procedure, it is necessary to surgeon adopts maneuver to carry out bending of titanium plate, with maxilla surface of fitting as far as possible, reach fixation. But regardless of Surgical technique, it is impossible to accomplish that titanium alloy blade plate is fitted bone surface form completely, therefore in fixation procedure, due to the gap between implants and skeleton, screw fixation procedure may result in stress deformation effect, the maxillary position making detachment produces mobile, causes surgical effect inaccuracy.
Utility model content
The purpose of this utility model is to provide a kind of mandibular distraction osteogenesis surgical guide, it is possible to accurate positioning, and has oozing of blood function.
According to an aspect of the present utility model, it is provided that a kind of mandibular distraction osteogenesis surgical guide, 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 of described connecting portion is connected with described fixed part; Described tooth support sector is provided with the cell body matched with mandibular anterior teeth denture; Being provided with the drainage trough oozed out for blood on described fixed part, described drainage trough is positioned at the centre position of described fixed part, and the two ends of described fixed part are provided with multiple fixing hole.
Wherein, in above-mentioned mandibular distraction osteogenesis surgical guide, one end of described fixed part is provided with three fixing holes, and the distribution mode of three described fixing hole triangularities is arranged, and the other end of described fixed part is provided with two fixing holes.
Wherein, in above-mentioned mandibular distraction osteogenesis surgical guide, each described fixing hole is the circular hole that diameter is 2mm.
Wherein, in above-mentioned mandibular distraction osteogenesis surgical guide, described tooth support sector, described connecting portion and described fixed part form as one formula structure.
Wherein, in above-mentioned mandibular distraction osteogenesis surgical guide, described connecting portion is formed as U-shaped, and one opening connects described tooth support sector, and another opening connects described fixed part.
A kind of mandibular distraction osteogenesis surgical guide 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 drainage trough, there is oozing of blood function.
Accompanying drawing explanation
Fig. 1 is the front view of the mandibular distraction osteogenesis surgical guide of this utility model embodiment;
Fig. 2 is the left view of the mandibular distraction osteogenesis surgical guide of this utility model embodiment;
Wherein:
1 is tooth support sector; 2 is connecting portion; 3 is fixed part; 4 is cell body; 5 is drainage trough; 6 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 mandibular distraction osteogenesis surgical guide 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 so that Intraoperative position is accurate, and osteotomy scope and osteotomy site not easily drift about. Being provided with the drainage trough 5 oozed out for blood on fixed part 3, this drainage trough 5 is positioned at the centre position of fixed part 3 so that this osteotomy guide plate has oozing of blood function. The two ends of fixed part 3 are 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.
In the present embodiment, connecting portion 2 is formed as U-shaped, and an opening of this connecting portion 2 connects tooth support sector 1, another opening connecting portion 3 of this connecting portion 2.
As it has been described above, a kind of mandibular distraction osteogenesis surgical guide of the present utility model, in place based on tooth, Intraoperative position is accurate, and osteotomy scope and osteotomy site not easily drift about, and are provided with drainage trough, have oozing of blood function.
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.
