Description
Technical field
The present invention relates to medical apparatus and instruments, particularly a kind of Wicresoft tooth implantation surgical drill.
Background technology
At present, to cut and to dig the main stream approach that two-period form cropping pattern that glutinous periosteum is principal character remains domestic and international tooth-implanting operation.This Dental Implant method will stick periosteum as alveolus and cut, and in art, wound is large, hemorrhage many, and the visual field is fuzzy, and operating time is long, and after-operation response is large, also may cause absorption and the gingival atrophy of alveolus hone lamella.Wicresoft's Dental Implant technology makes doctor no longer need can accurately perform the operation when cutting gingiva.Lobe tooth-implanting operation is turned over Comparatively speaking with traditional; Wicresoft's tooth-implanting operation in conjunction with 3D computer scanning location technology or sight location technology more notes the protection to diseased region and surrounding tissue thereof; farthest reduce wound; avoid or minimize after-operation response; reduce the generation of complication; shorten treatment time, patient's rehabilitation as early as possible can be made, and obtain more preferably repairing effect.
In Wicresoft's Dental Implant technology, the process of bore bone hole is particularly important, the direction in hole, the degree of depth, diameter and hole wall bone density, and cutting process and the time required for boring will directly affect the effect of Wicresoft's dental implant surgical.Conventional borehole needs first to bore with pioneer to beat directional hole, and then with the reaming step by step of multistage reaming fluted drill, program is comparatively complicated, and the time is long, and may cause surgical errors after repeatedly changing brill, severe patient even causes operative failure.So one-shot forming bone hole is extremely necessary.Then, it is large that traditional operation bores the area directly contacted with hole wall, and this just requires that the place that high accuracy is processed is many, brings inconvenience to batch production.Finally, traditional operation bores due to the existence of Os Sus domestica groove, and make the bone hole wall got very not smooth, the different place of some bone densities may produce crack, and this is also the great reason causing surgical effect not good.
Summary of the invention
Object of the present invention, is to solve the problems referred to above that prior art exists, provide a kind of can Wicresoft's tooth implantation surgical drill of one-shot forming bone hole.
The object of the present invention is achieved like this: a kind of Wicresoft tooth implantation surgical drill, comprises orientation punching head, the first reaming section, the second reaming section, main body reaming sizing section, scale section and locking section that order is connected; Directed punching head is conical structure; First reaming section is taper type structure, and the cone bottom diameter of its end diameter and the directed head that punches is identical; Second reaming section is patty structure, and its diameter is greater than the outside diameter of the first reaming section; Main body reaming sizing section is spiral cylinder body structure, and its diameter is greater than the diameter of the second reaming section; The diameter of scale section and locking section is less than the diameter of main body reaming sizing section.
The cylinder that the first described reaming section comprises the center of being arranged on and 4 conical lobes be axially connected on this cylinder, the both sides, outside of 4 conical lobes are respectively equipped with bias layer, and the outer ledge of each bias layer is respectively equipped with cutting edge.
The second described reaming section comprises a patty body, two arcuate grooves are circumferentially relatively provided with at patty body, the patty body of the side, same direction of two arcuate grooves is respectively equipped with bias layer, and each bias layer is respectively equipped with cutting edge towards arcuate groove one lateral edges.
Described main body reaming sizing section is provided with two helicla flutes and two spiral cylinders, and two helicla flutes and two spiral cylinder symmetries are interspersed.
The angle of inclination of the described upper conical lobe of the first reaming section is 50 ~ 60 degree, and the biased coefficient of the bias layer on conical lobe is 0.15-0.25.
The biased coefficient of the bias layer in the second described reaming section is 0.25-0.35.
Two helicla flute adaptations that two arcuate grooves in described second reaming section are shaped with described main body reaming in section are respectively communicated with.
Two spiral cylinders in bias layer in the first described reaming section, the bias layer in the second reaming section and main body reaming sizing section are all coated with one deck cobalt, and after the cutting edge portion cobalt plating of each bias layer, secondary puts the first edge on a knife or a pair of scissors.
By Wicresoft of the present invention tooth implantation surgical drill owing to have employed above technical scheme, there is following advantage and disadvantage:
1, can one-shot forming bone hole, simple to operate, convenient and practical.By orientation punching, first time reaming, second time reaming, finally extrude reaming and achieve the goal;
2, the bias layer of the first reaming section and the second reaming section makes stressed concentrating, the inclination angle γ of conical lobe in the first reaming section, make boring stressed minimum, make reaming procedure become quick, and the bone hole formed is more smooth than traditional; And bias layer edge secondary puts the first edge on a knife or a pair of scissors as cutting edge, make reaming quicker;
3, the setting of directed punching head and ascending twice reaming step by step, allows the possibility decreasing bone cracking in operation process, ensure that the success rate of operation, compensate for the shortcoming of one-shot forming bone hole;
4, the spiral cylinder in main body reaming sizing section extrudes bone wall after the second reaming completes, and reaches the size that bone hole requires, and makes large, smooth compared with other places of the density of bone hole wall, be conducive to the carrying out of subsequent procedures operation;
5, due to the existence of cutting edge place bias layer, so be limited to directed punching head, bias layer and spiral cylinder with the place that hole wall directly contacts, only need these parts to plate cobalt metal when production and processing and precision is processed, save a large amount of labours, be beneficial to popularization and the batch production of product;
6, scale part and inspecting hole part coordinate, and make manipulation doctor more easily hold operation progress, improve success rate of operation.
