Abstract
The invention discloses a novel medical abrasion drill. The novel medical abrasion drill is composed of a drill bit, a drill body and a drillstock. The novel medical abrasion drill is characterized in that the drill body is of a cone structure, one end, larger in diameter, of the drill body is connected with the drillstock, the drill body and the drillstock are integrally formed, one end, smaller in diameter, of the drill body is connected with the drill bit, and the drill bit is welded to the drill body. According to the medical abrasion drill, the cylindrical drillstock with a groove is adopted, the structure of combining the cone-shaped drill body with the drill bit which is of a triangular prism structure covered with small cuboid is adopted, two purposes of bone cutting and grinding are achieved, the integral installation is facilitated, and the drill bit is prevented from falling.
Description
Technical field
The invention belongs to Medical bit field, particularly relate to a kind of new medical abrasive drilling.
Background technology
Cutter on brill, drilling machine, drilling machine, can cause hole on workpiece or rock.Xu Chi " Goldbach's Conjecture's oil head ": " in 1956, China's bored material was somewhat nervous, and drill bit is not enough." 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 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, flourish along with medical and beauty treatment cause, drill bit have also been obtained at medical field and uses widely, but because the structure of structoure of the human body and machinery differs greatly, general drill bit well cannot 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.
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, it is characterized in that: 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 structure of described drillstock is cylinder, and described drillstock and drill body are monolithic molding, 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 Rhizoma Sparganii cylinder, the surface of described triangular prism body structure is covered with the little cuboid distributed at certain intervals, the spacing distance of described little cuboid is at 0.5mm ~ 1mm, the width of described little cuboid is 0.5mm ~ 1mm, be highly 0.05mm ~ 0.1mm, described little cuboid and triangular prism body structure is whole is structure as a whole, the drill bit of described triangular prism body structure, symmetrical on direction, axis, Rhizoma Sparganii cylinder is 15 ~ 25 ° at axis direction and the horizontal angle number of degrees, the height of the drill bit of triangular prism body structure is 2 ~ 4cm, the greatest length of the drill bit of triangular prism body structure 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 a slender cylinder, and the groove of 2 semicircle strips is offered in described cylinder drillstock periphery, and the diameter of described slender cylinder is 2 ~ 3cm, and length is 7 ~ 8cm.
Further, the diameter of the bottom surface circle of described Rotary-table drill body is identical with the cross section round diameter of described slender cylinder drillstock.
Beneficial effect of the present invention is as follows:
1, medical grinding bit of the present invention have employed the reeded cylinder drillstock of band, and the structure that Rotary-table drill body combines with the drill bit of the triangular prism body structure being covered with little cuboid reaches and cuts bone, and mill bone is dual-purpose, and is beneficial to whole installation, avoids coming off of drill bit;
2, the drill bit being covered with the triangular prism body structure of little cuboid of the present invention, the little cuboid spacing distance of triangular prism surface controls at 0.5 ~ 1mm, and the triangular prism surface of short spacing is when rubbing with bone, rubbing action can be played well, make rubbing surface smooth.Meanwhile, the front end of the brill of triangular prism body structure is 15 ~ 25 ° at axis direction and the horizontal angle number of degrees, can directly carry out the operation of cutting bone, really realize effect that a brill is dual-purpose;
3, cylinder drillstock of the present invention is provided with upper and lower two grooves, is easy to the installation of machine, also fastens installation simultaneously, plays the effect of slip-off preventing.
