Description
Technical field
The present invention relates to the medical miniature bone grinding knife tools and its manufacture craft of a kind of abrasive particle ordered arrangement, belong to accurate mill
Processing technique field is cut, in terms of being chiefly used in medicine.
Background technology
Bone tissue grinding technique is widely used in neurosurgery, backbone due to its fine and smooth, obtuse processing characteristic
The fields such as surgical operation, dentistry.Compared with the cutting element for generating big chip, the mechanical damage that diamond grinding tool is brought compared with
It is small.The miniature bistrique of diamond sold on the market at present, diameter 4-5mm, grit size are tens to hundreds of microns, abrasive particle be in
Machine is arranged, and bonding mode is electronickelling.There are two key issues for electroplating abrasion wheel grinding bone tissue.One is grinding heat, due to
Grinding is energy-intensive processing method, and most of energy expenditure is converted into thermal energy, and research shows that diamond abrasive tool is being ground
The quantity of heat production of process is cut apparently higher than the quantity of heat production of cut drill.And the ability of Human Tolerance high temperature is poor, when temperature is higher than 50
DEG C, bone is present with different degrees of thermal damage, and nerve fiber is more sensitive to temperature, and the critical temperature value of thermal damage is 43
℃.Secondly it is bistrique blockage problem, due to containing a certain amount of polysaccharide protein, the bone tissue abrasive dust in grinding process in bone tissue
It is easy to be adhered to the formation blocking of bistrique surface under higher grinding temperature and extrusion stress effect.Research shows to work as use
When the progress bone tissue wet-milling of diamond spherical grinding tool is cut, serious bistrique blockage problem is also run into, a large amount of bones bits are viscous after being ground
Be attached on grinding tool, especially with reference to agent material at.
The content of the invention
In order to overcome the shortcomings of that the grinding heat of existing bone tissue grinding technique is higher, be susceptible to blocking, the present invention provides
A kind of grinding heat is not easy to accumulate, be less prone to the medical miniature bone grinding knife tool and its system of the abrasive particle ordered arrangement of bistrique blocking
Make technique.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of medical miniature bone grinding knife tool of abrasive particle ordered arrangement, is divided into working portion cutter head and holding handle two
Point, working portion is made of cutting insert substrate, diamond abrasive grain and brazing metal bonding agent three parts, working portion and clamping part
It is divided into integral；Working portion cutter head is microsphere, and the diamond abrasive grain arranged thereon is in ordered arrangement.
Further, the ordered arrangement refers to diamond abrasive grain along working portion circular manner horizontal arrangement, in each layer
Diamond abrasive grain is equal with the distance of left and right adjacent abrasive grains, and the abrasive particle between different layers is also along the distance of spherome surface
Equal.
Either：The ordered arrangement refers to that diamond abrasive grain is tiltedly arranged along working portion circular manner, golden in each layer
Hard rock abrasive particle is equal with the distance of left and right adjacent abrasive grains, and the distance of abrasive particle along spherome surface between different layers is also phase
Deng.
Again either：The ordered arrangement refers to that diamond abrasive grain is arranged along working portion perficial helical, gold on helix
Hard rock abrasive particle is equal with the distance of left and right adjacent abrasive grains.
A kind of preparation method of the medical miniature bone grinding knife tool of abrasive particle ordered arrangement, comprises the following steps：
(1) need to screen abrasive particle size, species and particle size range according to actual preparation；
(2) tool matrix of size, especially working portion will be prepared and carry out removing surface；
(3) ordered arrangement drills on working portion bulb；
(4) abrasive particle and soldering flux are filled into arrangement hole, placed in a vacuum furnace；
(5) design temperature is first heated to, and keeps the temperature placement a period of time, extra binding agent is removed after final furnace cooling and is not consolidated
Fixed complete diamond abrasive grain.
In the present invention, soldering tech can make to form enhanced primary treatment between diamond and solder, be conducive to improve single
The height of protrusion of diamond and working time, and then improve the stock-removing efficiency and service life of instrument；Ordered arrangement can be formed
Ideal grinding landforms realize the exposed height of consistent abrasive particle and rational abrasive particle spacing, improve the chip removal ability of grinding tool,
Solve the accumulation of grinding heat and the blockage problem of bistrique.The present invention key point be how minute diameter (4-5mm) ball
The ordered arrangement of abrasive particle is realized on head.
Beneficial effects of the present invention are mainly manifested in：The accumulation of grinding heat and the blockage problem of bistrique are solved, grinding heat is not
It easily accumulates, be less prone to bistrique blocking.
