Description
Technical field
This utility model belongs to medical assistance instrument field, is specifically related to a kind of guide plate for orthognatic surgery.
Background technology
In the treatment to cranium maxillofacial development deformation patients, often need to be come from the disconnected upper jaw, lower jaw and/or chin portion bone by surgical operation, moved to correct position and carry out bone block in this position and fix, set up stable occluding relation, such operation is called orthognathic surgery simultaneously.The patient that simultaneously need carry out upper and lower jaw operation first determines the position of upper jaw bone movement after lancing in art by the position that lower jaw is preoperative, moved by upper jaw bone and after fixing, then is fixed the position of mandibular bone by upper jaw bone.In art, instruct the device of upper and lower jawbone position to be called plywood, be called middle plywood for what locate upper jaw bone, be called last plywood eventually for what locate mandibular bone.Usually on the upper and lower jaw plaster model of patient, surgical simulation is carried out by cutting plaster model in existing orthognatic surgery, and on the model of having simulated, adopt self curing plastic successively to make middle plywood and whole last plywood, in order to the operation of simulation to be transferred on operating-table.Terminate future trouble person in operation and need to bite last plywood eventually, by elastic tape or steel wire, upper lower jaw Wiring dentition was fixed at least 4 weeks.
Patent CN201420093818.8 discloses one " the middle guide plate for upper jaw bone location in orthognathic surgery ", this middle guide plate comprises a shape of a hoof guide plate (plywood), its upper surface has and to close upper tooth that face portion matches with the tooth of upper denture and print and remember, the left and right sides is provided with connected structure, the each little location-plate in left and right, and each first connector in left and right and the second connector.During use, shape of a hoof guide plate is seated in the upper denture of patient, first the first connector is connected with little location-plate, and settle little location-plate in the surface of bone of infraorbital foramen lower edge, with little location-plate lower edge for osteotomy line position carries out osteotomy, re-use the second connector and connect shape of a hoof guide plate and little location-plate, upper jaw bone bone block is moved to target location.Although this middle guide plate accurately can locate upper jaw bone block position before bone block maintenance, but this guide plate completes whole operation needs two little location-plates, two cover connector and a shape of a hoof guide plates, and described shape of a hoof guide plate is just for the middle guide plate of upper jaw bone location in orthognathic surgery, making one piece end last guide plate is also needed as whole operation process need be completed, fix for postoperative ligation, thus need the component of 3 D-printing more.Due to 3 D-printing costly, and guide plate used of performing the operation is disposable using apparatus, thus can increase the financial burden of patient and cause the waste of material.
