Description
Technical field
This utility model relates to a kind of medical aid, in particular a kind of artificial remporomandibular joint displacement bone finishing guide plate component.
Background technology
The artificial remporomandibular joint of standard type cannot be mated completely with patient's jawbone form, so must adapt to the jawbone finishing of prosthese profile to each patient, is mainly upper jaw bone zygomatic arch, articular tubercle, condyle of mandible and ascending branch lateral surface.And for jawbone finishing, the domestic instrument that is applied to the finishing of clinical guidance bone that there is no, therefore, bone finishing has certain blindness, can cause unnecessary bone amount loss.Secondly, because bone finishing grinding sclerotin is cortical bone, be the hardest part of jawbone, blindly jawbone intensity is greatly lowered in grinding meeting, and zygomatic arch self thinner thickness, and blindly may to cause top prosthese be artificial articular fossa in grinding, cannot row Screw retained; Again, due to the nearly basis cranii of upper jaw bone zygomatic arch bone trim locations, have a big risk, if grinding too much has damage basis cranii, causes cerebrospinal leak possibility; And condyle of mandible inner side is artery and vein vascular bundle traveling in jaw, during bone finishing, easy damaged causes massive hemorrhage, so need guide plate to assist accurate osteotomy, reduces neural, blood vessel injury risk.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of artificial remporomandibular joint displacement bone finishing guide plate component is provided, and can facilitate in art and use, accurately shows upper position, mandibular bone grinding part and osteotomy direction.
This utility model is achieved through the following technical solutions, and this utility model comprises articular tubercle guide plate, zygomatic arch guide plate, the prominent guide plate of condyle, ascending branch guide plate;
Described articular tubercle guide plate is attached at zygomatic arch lateral surface, and the lower edge of articular tubercle guide plate is bladed or with shoulder, the surface of articular tubercle guide plate is provided with screw hole and the auxiliary positioning hole of mating with glenoid fossa prosthese;
Described zygomatic arch guide plate is attached at zygomatic arch lateral surface, and zygomatic arch guide plate is that U-shaped, U-shaped opening is bladed, and a plurality of auxiliary positioning hole is offered at edge;
The prominent guide plate of described condyle is attached at the prominent lateral surface of condyle, on the prominent guide plate of condyle, offers a plurality of screw holes, and the top edge of the prominent guide plate of condyle is bladed or is provided with shoulder;
Described ascending branch guide plate is attached at Mandibular Rumas lateral surface, the top hollow out of described ascending branch guide plate, and described hollow out position is bladed, ascending branch guide plate is provided with the screw hole matching with the prominent prosthese of condyle.
As one of optimal way of the present utility model, the bladed portion of described articular tubercle guide plate or the width of shoulder are 2.5mm.
As one of optimal way of the present utility model, the prominent bladed portion of guide plate of described condyle or the width of shoulder are 2.5mm.
As one of optimal way of the present utility model, the guide plate body thickness of described articular tubercle guide plate, zygomatic arch guide plate, the prominent guide plate of condyle, ascending branch guide plate is 1.5mm.
In art, employing improvement preauricular incision+lower jaw lower cut fully exposes zygomatic arch, condyle is prominent and Mandibular Rumas, fits tightly respectively, firmly maintenance by operation designing order by wearing into and make it via the guide plate of plasma or oxirane disinfection with surface of bone; Press again the middle hollow out scope of the prominent guide plate of zygomatic arch guide plate and condyle and edge indication osteotomy direction or implement bone finishing, then lay under articular tubercle guide plate and ascending branch guide plate guiding articular tubercle facial bone finishing and prosthese punching location outside osteotomy, ascending branch, finally lay prosthese and with titanium screw maintenance.Because the prominent guide plate of articular tubercle guide plate and condyle edge accurately shows osteotomy direction, zygomatic arch guide plate and ascending branch guide plate openwork part accurately show bone grinding scope and the degree of depth, articular tubercle guide plate and ascending branch guide plate be exact matching prosthese hole, can guarantee that thus prosthese implants by Design, realized Design to the transition of applying in art, guarantee the accuracy of operation, at utmost reduced the loss of bone amount, guaranteed the effect of standard type remporomandibular joint.
This utility model has the following advantages compared to existing technology: this utility model can make perform the operation bone finishing of standard type prosthetic replacement more easily carry out, and is convenient to patient's operation, greatly shortens operating time; Accurately instruct upper jaw bone articular tubercle bottom osteotomy, condyle of mandible amputation and zygomatic arch lateral surface, the grinding of ascending branch lateral surface, protect basis cranii and the condyle important neurovascular bundle of medial surface traveling of dashing forward simultaneously, through guide plate, instruct sending down the fishbone finishing more accurate, reduce unnecessary bone amount loss; Through guide plate instruct sending down the fishbone finishing can good protection anatomical structure around, avoided the neural blood vessel damage of bone dressing area; Guide plate application has realized Design to the conversion operating in art, guarantee that artificial joint implants at ideal position, guaranteed the effect of artificial joint, reduce to greatest extent bone trim amount, increase artificial joint prosthesis and jawbone laminating degree, reduce the generation of post-operative complication in art, improve the result of use of standard type artificial joint prosthesis.
