Abstract
The invention discloses a novel medical abrasion drill which comprises a drill bit, a drill body and a drill shank. The drill body is structurally a circular truncated cone, a large-diameter end of the drill body is connected with the drill shank, the drill body is connected with the drill shank in a welded manner, a small-diameter end of the drill body is connected with the drill bit, and the drill bit is connected with the drill body in a welded manner. The novel medical abrasion drill has the advantages that the novel medical abrasion drill is provided with the hexagonal drill shank, the drill body which is the circular truncated cone is structurally combined with the solid irregular pentahedral drill bit with dense solid small dots, accordingly, the novel medical abrasion drill can be used for cutting and abrading bones and can be integrally mounted advantageously, and the drill bit can be prevented from falling off.
Description
Technical field
The invention belongs to Medical bit field, particularly relate to a kind of new medical abrasive drilling.
Background technology
Drill bit is a kind of rotation and head end has the instrument of cutting power, general with carbon steel SK, or high-speed steel SKH2, the materials such as SKH3 through milling or rolling again through quenching, grind after tempering heat treatment and form, Drilling operation on metal or other materials, its scope of application is extremely wide, can apply to the toolroom machines such as drilling machine, lathe, milling machine, electric hand drill use.
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, in the last few years, and flourish along with medical and beauty treatment cause, drill bit is also used gradually at medical field, but existing medical abrasive drilling mill bone is coarse, using function is comparatively single, cannot better use at medical field.
Summary of the invention
The technical problem to be solved in the present invention is that drill bit is coarse for medical treatment mill bone, mill bone, cuts bone and cannot complete simultaneously, and drill bit is easy to the problem come off at work.
For solving the problem, the invention 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, 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, and the connected mode of described drill bit and drill body is welding type.
Further, the structure of described drill bit is solid irregular pentahedron, the surface of described solid irregular pentahedron structure is covered with the solid dot distributed at certain intervals, the spacing distance of described solid dot is at 0.5mm ~ 1mm, described solid dot and solid irregular pentahedron structure is whole is structure as a whole, described solid irregular pentahedral drill bit, symmetrical in the axial direction, solid irregular pentahedron is 35 ~ 55 ° at the number of degrees of axis direction drift angle foremost, and the height of solid irregular pentahedral drill bit is 4 ~ 6cm.
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 5 ~ 6cm.
Further, the structure of described drillstock is an elongated hexahedron, and length is 5 ~ 7cm.
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.
Further, the pentagonal circumscribed diameter in cross section of described solid irregular pentahedral drill bit is identical with the diameter of the cross section circle of described Rotary-table drill body.
Beneficial effect of the present invention is as follows:
1, medical grinding bit of the present invention have employed the drillstock of hexahedron, the structure that the drill body of Rotary-table and the solid irregular pentahedral drill bit being covered with solid dot combine, and reach and cut bone, mill bone is dual-purpose, and is beneficial to whole installation, avoids coming off of drill bit.
2, the solid irregular pentahedral drill bit being covered with solid dot of the present invention, 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, the operation of cutting bone can directly be carried out in the front end of solid irregular pentahedral drill bit, really realizes effect that a brill is dual-purpose.
3, hexahedron drillstock of the present invention, 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.

If Fig. 1 is structural representation of the present invention.
If Fig. 2 is drill bit partial enlarged drawing of the present invention.
As the side view that Fig. 3 is structure of the present invention.
Detailed description of the invention
Drawing reference numeral: 1, drill bit, 2, drill body, 3, drillstock, 4, solid dot
For making goal of the invention of the present invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
The structure of medical grinding bit of the present invention as shown in Figure 1, a kind of new medical abrasive drilling, be made up of drill bit 1, drill body 2 and drillstock 3 three part, the structure of drill body 2 is Rotary-table, one end that the diameter of drill body 2 is large is connected with drillstock 3, drill body 2 is welding type with the connected mode of drillstock 3, and one end that the diameter of drill body 2 is little is connected with drill bit 1, and drill bit 1 is welding type with the connected mode of drill body 2.The structure of drill body 2 is Rotary-table structure, and the maximum gauge of Rotary-table is with minimum diameter than being 3:1, and round platform height is 5 ~ 6cm.Have employed the drillstock of hexahedron, the structure that the drill body of Rotary-table 2 and the solid irregular pentahedral drill bit 1 being covered with solid dot 4 combine, reach and cut bone, mill bone is dual-purpose, and is beneficial to whole installation, avoids coming off of drill bit.
