Description
Technical field
The present invention about a kind of drilling into bone positioning guidance device, espespecially a kind of can in order to the auxiliary positioning guidance device of to hole to bone or implanting implant.
Background technology
In traditional surgical method, doctor is mainly by X-ray or the CT Scan (ComputerizedTomography of sufferer skeleton, CT) image, and coordinate self anatomical knowledge and clinical operation experience to plan the intrusion position of operation and to invade path, therefore degree of accuracy during operation, safety and reliability extreme are dependent on the clinical experience of doctor.Therefore, for the doctor that experience is comparatively not enough, often there is the problem being difficult to grasp operation quality.With surgery (orthopaedics) doctor, implant the position of nail and angle quite important, the neural and blood vessel of trauma etc. should be avoided, otherwise the sequela that hemiplegia etc. can be caused serious.
With dentist, when the tooth of people has damage or pulled out, general therapeutic modality installing artificial tooth replaces original dermal tooth, and the mode of installing artificial tooth common at present adopts fixed artificial to plant tooth.It is the nest hole first getting out suitable size at the suitable place of dental bed bone at patient's intraoral dental bed agomphosis place that fixed artificial plants tooth, then an artificial tooth root is implanted into and sew up wound in this nest hole again, until this artificial tooth root after dental bed bone grows together completely, platform tooth, finally a sheathed artificial artificial tooth on this platform tooth with screw is locked again on this artificial tooth root.This artificial artificial tooth can be made to be supported by dental bed bone completely by means of this artificial tooth root and a platform tooth with screw, and then make this artificial artificial tooth can bear the gmatjpdumamics of upper and lower row's tooth, reach the object of the meshing functions recovering tooth.
Wherein, the degree of depth in above-mentioned got out nest hole, angle, position and size can be related to the degree of depth that subsequent artefacts's root of the tooth imbeds dental bed bone and the position of planting on dental bed bone, even have influence on plant tooth complete after the occlusion of artificial artificial tooth and corresponding tooth; Again, in order to avoid the dental bed bone of patient crumbles in the process being drilled with nest hole because of factors such as osteoporosises, first in the nest hole that the first drilling bore hole footpath of dental bed bone is less, then must progressively expand the aperture in this nest hole again.
Prior art can in order to assist the drilling aid being drilled with nest hole on dental bed bone as Taiwan certificate count No. I285099 " tooth root location drilling auxiliary device for artificial implanted tooth " patent of invention case, and shown in No. M256496th, Taiwan certificate count " implant dental drill hole positioning auxiliary device " new patent case, it mainly borrows magnetic force to adsorb the fairlead of multiple layers of semicircle demihull shape with overlapped way in the outside of the baseline rod of a tool magnetic, the radius of curvature of each fairlead increases progressively from the fairlead being positioned at innermost layer and being attached at baseline rod gradually to being positioned at outermost fairlead.
Doctor can utilize the drilling aid of above-mentioned prior art on the dental bed model of patient, first simulate angle and the aperture size in the nest hole that agomphosis place needs, make the guiding mould that can be sheathed on agomphosis place on patient's dental bed accordingly, this guiding mould is provided with groove for this drilling aid accommodating at corresponding agomphosis place.When holing to the dental bed bone of patient, first take off this baseline rod, follow this angle that arranges being positioned at the fairlead of innermost layer with the drill point that bar footpath is identical with the radius of curvature of the fairlead being positioned at innermost layer again and nest hole is established to dental bed bone drill downwards, then divest the fairlead that this is positioned at innermost layer, and change and follow this angle that arranges being positioned at the fairlead of time one deck with the drill point that bar footpath is identical with the radius of curvature of the fairlead of time one deck and reaming is carried out to nest hole established on this dental bed bone downwards.So sequentially divest fairlead and with the use of the drill point with different bar footpath, can progressively by the borehole enlargement in the nest hole on dental bed bone to required size.
Only, the drilling aid of above-mentioned prior art is all only put merely in the groove of guiding mould, this drilling aid there is no any can be combineding with each other fixing design with guiding mould, therefore both easy relative shifts, cause the nest hole that cannot get out in precalculated position and have precalculated position, angle of inclination and direction.Moreover, although can utilize between the datum plate of this drilling aid and fairlead and be drilled with fixing hole at this datum plate and fairlead, the mode of fixing hole is run through again with fixture, fix the relative position of this baseline rod and fairlead, but, in the situation being drilled with nest hole on dental bed bone as above, the size of this baseline rod and fairlead will certainly be similar with tooth, need to design quite exquisite, therefore to be drilled with fixing hole further on the baseline rod and fairlead of size exquisiteness again and running through with fixture, no matter all suitable degree of difficulty can be had in manufacture or in operation, therefore the drilling aid of prior art still needs to improve part further.
Summary of the invention
