Orthognathic surgery will have odd-shaped bones of facial cranium to recover its normal anatomic form with operating method, yet the spatial displacement of lopsided jawbone or bone grafting moulds profile again in operation, these were entirely with the experiential operating of operator in the past, yet surgical experience is to be difficult to quantizedly, and same position operator may successively be operated all and there are differences.Originally orthognathic surgery includes cosmetic purpose, but because no reference value quantizes operation process, so be difficult to satisfy by patient's beauty treatment requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of viscerocranium position finder, and is simple in structure, easy to use, the accurate positioning of bone piece, better reduction.
Use the viscerocranium position finder to measure the tissue mass of jaw face or distance value that bone should move in advance or calculate and need the tissue mass transplanted, this can significantly reduce operation risk not in place, also can carry out the postoperative prediction simultaneously.Craniometry is one of means of anthropological studies, and the viscerocranium positioning rule also can be used in the anthropolgical measurement Research, and measurement value of obtaining and the instrument that uses can be applied to clinical treatment simultaneously, to reduce the transformed error in the transition.
In order to achieve the above object, this utility model adopts following technical measures:
The viscerocranium position finder is made up of facebow, ears bar, two slip positioning rule and parts such as " rail limits ".Its positioning principle is: the facebow main body is that 180 degree cut arcs by one sections of angles, and the summit of ears bar and two slip chis is all facing to 0 point of facebow.After " 0 " point was determined, slip chi fixed point was all measurable in spatial any site, according to reference each other about the symmetry principle event.On the two ear bars scale, bolt are arranged, after the ear bar stretched into the locking of external auditory meatus symmetry, its baseline was cut " pharyngeal tubercle " approximately, and pharyngeal tubercle is also aimed on the summit of the chi that slides this moment, slide on hemisphere face as basic point " rail limit ", read the space coordinates point value by moving of slip chi.The maintenance bolt is all arranged for locking usefulness on two slip chis and " the rail limit ", can a chi, rail fixes, another chi, rail slide measurement.Therefore, about interactive, decide combination, thereby mutual value reference.
The viscerocranium positioning rule is the metal quality, and the sterilization that carries out disinfection of available conventional surgical sterilization of instruments method is ready for use among the operation with the surgical operating instrument sterilization of packing.
This utility model compared with prior art has the following advantages and effect:
1, when fracture operation resets, the bone piece of desiring to reset accurately can be located, this feels to be difficult to accomplish with the operator individual.
2, can calculate the osseous tissue amount of lopsided maxillofacial bone displacement or reparation in orthognathic surgery with this instrument, this rescues the cosmetic result that reaches with tradition with the operator experience and has qualitative difference.
3, the survey cranium instrument of traditional antropology use can not be used for operating room, because it is by measuring free skull design.
