Abstract
The utility model discloses a kind of new medical abrasive drilling, by drill bit, drill body and drillstock three part form, the structure of described drill body is Rotary-table, one end that the diameter of described drill body is large is connected with drillstock, the connected mode of described drill body and drillstock is welding type, one end that the diameter of described drill body is little is connected with drill bit, and the connected mode of described drill bit and drill body is welding type, and the structure of described drill bit is solid sphere.The utility model has the advantage of: medical grinding bit have employed the drillstock of hexahedron, the structure that the drill body of Rotary-table and the solid sphere drill bit being covered with black circle combine, reach and cut bone functionality by force, not other positions of easy damaged human body, and effect is easily installed.
Description
Technical field
This utility model belongs to Medical bit field, particularly relates to a kind of new medical abrasive drilling.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, centre drill, chit drill, depth drill and cylindrical drill.Though reamer counterbit can not be holed on solid material, also they are included into drill bit one class traditionally.Work process dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit.
Drill bit obtains at mechanical field and uses widely, and in the last few years, flourish along with medical and beauty treatment cause, drill bit have also been obtained at medical field and uses widely, and medical grinding bit of the prior art exists cutting effect difference, the shortcoming that purposes is comparatively single.
Utility model content
The technical problems to be solved in the utility model is that drill bit cuts bone for medical treatment, mill bone is coarse, irregular problem.
For solving the problem, this utility model provides following technical scheme: a kind of new medical abrasive drilling, by drill bit, drill body and drillstock three part form, its innovative point is: the structure of described drill body is Rotary-table, one end that the diameter of described drill body is large is connected with drillstock, and the connected mode of described drill body and drillstock is welding type, and one end that the diameter of described drill body is little is connected with drill bit, the connected mode of described drill bit and drill body is welding type, and the structure of described drill bit is solid sphere.
Further, the structure of described drill body is Rotary-table structure, and the maximum gauge of described Rotary-table is with minimum diameter than being 3:1, and round platform height is 7 ~ 10cm.
Further, the surface of the drill bit of described solid sphere structure is covered with the solid dot distributed at certain intervals, the spacing distance of described solid dot is at 0.5mm ~ 1mm, described black circle and medicine ball is whole is structure as a whole, the volume ratio of described solid dot and solid sphere is 1:150.
Further, the structure of described drillstock is an elongated hexahedron, and length is 9 ~ 12cm.
Further, the diameter of the cross section circle of described Rotary-table drill body is identical with the orthohexagonal inscribed circle diameter in cross section of described elongated square drillstock.
The beneficial effects of the utility model are as follows:
1, medical grinding bit of the present utility model have employed the drillstock of hexahedron, the structure that the drill body of Rotary-table and the solid sphere drill bit being covered with black circle combine, and reaches that to cut bone functionality strong, not other positions of easy damaged human body, and installs effect easily.
2, the solid sphere drill bit being covered with black circle of the present utility model, the black circle spacing distance on solid sphere surface controls at 0.5 ~ 1mm, when the solid sphere surface of short spacing is that bone rubs, rubbing action can be played well, make rubbing surface smooth.Meanwhile, circular surface, for other positions of human body, also not easily causes damage.
3, hexahedron drillstock of the present utility model, is easy to the installation of machine, also fastens installation simultaneously, plays the effect of slip-off preventing.Meanwhile, when drillstock is placed in smooth flat, also can play a good support effect, prevent from rolling, cause the damage that abrasive drilling is unnecessary.

Detailed description of the invention
Drawing reference numeral: 1, drill bit, 2, drillstock, 3, drill body, 4, solid dot
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
The structure of medical grinding bit of the present utility model as shown in Figure 1, a kind of new medical abrasive drilling, be made up of drill bit 1, drill body 3 and drillstock 2 three part, the structure of drill body 3 is Rotary-table, one end that the diameter of drill body 3 is large is connected with drillstock 2, drill body 3 is welding type with the connected mode of drillstock 2, and one end that the diameter of drill body 3 is little is connected with drill bit 1, and drill bit 1 is welding type with the connected mode of drill body 3.The structure of drill body 3 is Rotary-table structure, and the maximum gauge of Rotary-table is with minimum diameter than being 3:1, and round platform height is 7 ~ 10cm.Have employed the drillstock of hexahedron, the structure that the drill body of Rotary-table 3 and the solid sphere drill bit 1 being covered with solid dot 4 combine, reach before cutting bone functionality, not other positions of easy damaged human body, and effect is easily installed.
Drill bit 1 partial enlargement of medical grinding bit of the present utility model as shown in Figure 2, the structure of drill bit 1 is solid sphere, drill bit 1 surface of sphere structure is covered with the solid dot 4 distributed at certain intervals, the spacing distance of solid dot 4 is at 0.5mm ~ 1mm, when solid sphere drill bit 1 surface of short spacing is that bone rubs, rubbing action can be played well, make rubbing surface smooth.Meanwhile, circular surface, for other positions of human body, also not easily causes damage.Solid dot 4 is structure as a whole with solid sphere drill bit 1 is whole, and solid dot 4 is 1:150 with the volume ratio of solid sphere drill bit 1.
The top view of medical grinding bit of the present utility model as shown in Figure 3, the structure of drillstock 2 is an elongated hexahedron, length is 9 ~ 12cm, the diameter of the cross section circle of Rotary-table drill body 3 is identical with the orthohexagonal inscribed circle diameter in cross section of described elongated square drillstock 2.Hexahedron drillstock 2, is easy to the installation of machine, also fastens installation simultaneously, plays the effect of slip-off preventing.Meanwhile, when drillstock 2 is placed in smooth flat, also can play a good support effect, prevent from rolling, avoid the damage causing abrasive drilling unnecessary.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of this utility model patent.
