Description
Technical field
The invention belongs to technical field of medical instruments.More particularly to a kind of grinding technology and dress of nano ceramics scalpel
It is standby.
Background technology
Conventional steel disposable surgical knife perishable, passivation when using with heating disinfection, the life-span is low;Diamond scalpel
Processing technology is complicated, and transparent, operating difficulties is expensive.Nano ceramics operation edge is sharp, and no magnetic is nontoxic, no electrostatic,
Long lifespan, anticorrosion, with raw body histocompatbility, precision is high, and the edge of a knife can quickly heal, postoperative without obvious cut channel, it is easy to grasp
Make, can use at high temperature, and can repeatedly use, never wornout, moderate cost.In ophthalmology, department of plastic surgery, blood vessel hand
The fields such as art, microsurgery, neurosurgery, skin grafting have is widely applied prospect very much.But nano ceramics extreme hardness, though
Right toughness improves many compared with conventional ceramic, but compared with the Cr6 materials of coventional scalpel for, toughness is still very low, to grinding edge
Tipping occurs for Shi Jiyi, therefore traditional diamond-making technique yield rate is very low, causes nano ceramics scalpel price very high.The present invention will
ELID grinding techniques are used to prepare nano ceramics scalpel, Fixture for sharpening are voluntarily developed, to the surface matter of nano ceramics scalpel
Amount, radius of edge are processed, and successfully prepare qualified nano ceramics arcuate blade scalpel, and realize that small lot is produced.
The content of the invention
Traditional operation knife is typically manufactured with 3Cr13 and 4Cr13 martensitic stain less steels and 9Cr18 rustproof spring steels etc., its
Method of manufacturing technology is produced in batches using forging method;But nano ceramics scalpel hardness is higher, fragility is larger, because
The manufacture method of this Conventional nano ceramic scalpel is unsuitable for producing nano ceramics scalpel.
There is the following shortcoming when being ground nano ceramics scalpel in traditional method for grinding:
Easy tipping.Because grinding machine spindle running accuracy is relatively low, feed speed is unstable, impact of the emery wheel to cutting edge during grinding
Cutting edge tipping can be caused.
Precision is low.Surface roughness reaches Ra0.2 μm, 1.3-2.5 μm of radius of edge.
Efficiency is low.Due to using universal fixturing, a scalpel can only be ground every time, therefore grinding efficiency is low.
Yield rate is low.Impact of the plain grinding method to cutting edge causes tipping, and cutter yield rate is relatively low, and cost is very high.
Straight sword scalpel can only be ground on plain clamp, arcuate blade scalpel can not be ground.
Because traditional method for grinding has the shortcomings of easy tipping, efficiency are low, cost is high, therefore to solve the above problems, carry
Go out with online electrochemical grinding technology(ELID, Electrolytic In-process Dressing)Processing operation edge, by
Layer oxide film is covered in ELID surfaces of grinding wheels, the oxide-film has effectively isolated the vibration of machine tool chief axis, therefore avoids
Impact of the vibration to cutting edge, efficiently solves the problems, such as cutting edge tipping, improves the yield rate of nano ceramics scalpel.While oxygen
Change film and be rich in alpha-ferric oxide polishing agent in itself, possess polishing action, can further improve grinding edge precision, be ground using ELID
Technology realizes high-precision sharpening, and radius of edge reaches 200nm, and cutting edge roughness reaches 6nm.And a set of work of self design
Skill is equipped, while meeting high efficiency requirement, using the set technological equipment, a set of equipment clamped one time can sharpen 18-36 simultaneously
Scalpel, therefore, it is possible to which nano ceramics scalpel manufacturing cost is greatly reduced.
What the present invention was realized in:
First with the mounting groove of homemade Ultrasonic machining instrument scalpel in manuscript 1 on ultrasonic machining unit.And roughly grind
Scalpel two sides, realize pre-determined bit during for sharpening.
Secondly scalpel is preheated 200-300 DEG C with resistance furnace, one side applies fixing glue, and installed in Fig. 2 positioning fixtures
On, pre-determined bit is realized by flange on the mounting groove and positioning fixture of scalpel and that scalpel mounting groove is engaged, will be performed the operation
The side of cutter painting glue is pressed on the end face of positioning fixture, is allowed to fastening adhesion, and is dried up with blower fan, is cooled to room temperature.
3rd, the positioning fixture for being provided with scalpel is arranged on the self-control Fixture for sharpening shown in Fig. 3, noted during installation
Sword arc shape one side perform the operation to turntable outer rim, and it is tangent with turntable outer rim.The fixture is made up of turntable and sinetable, and turntable is used for
The swivel feeding requirement of curved edge when realizing grinding, sinetable then realizes the angle adjustment of sharpening cutting edge.Therefore the fixture
Meet while being ground the requirement of cutting edge radian and angle, the cutting edge for preferably realizing arc scalpel is sharpened.In addition, turning
18-36 scalpel positioning fixture can be arranged on platform circumference simultaneously(Depending on model, size depending on scalpel), every revolution,
The cutting edge of 18-36 scalpel can be processed, it is achieved that the middle small serial production of scalpel, improves processing efficiency, reduction manufacture
Cost.
4th, Fixture for sharpening is arranged on ELID surface grinding machines, fastened with the trip bolt of bottom, if lathe has magnetic
Power sucker, then be not required to fastening.Lathe is started, the sharpening of cutting edge side is carried out, 20 ° of every turn of turntable clamper is (along turntable circumference uniform distribution
18 scalpels) or 10 °(Along 36 scalpels of turntable circumference uniform distribution)The sharpening of a scalpel is then completed, after rotating one week,
Whole scalpel sharpenings are finished.
5th, sharpen behind cutting edge side, positioning fixture is unloaded, heated on resistance furnace, after after glue fusing, take down operation
Knife, after cleaning up, air-drying in ethanol solution, in scalpel opposite side gluing, and is pasted onto on positioning fixture, then will be fixed
Position fixture is installed on Fixture for sharpening turntable again, carries out the sharpening of the opposite side cutting edge of scalpel.Because the 4th step has been sharpened
Offside cutting edge, therefore when being ground opposite side, cutting edge is thinning, and also opposite side is hanging, does not support, easily causes cutting edge to collapse
Sword.Now need to add auxiliary voussoir as shown in Figure 4 in the hanging side of cutting edge, the voussoir profile is identical with scalpel, is also
Realized using scalpel mounting groove and positioning be installed, cutting edge position angle and scalpel on the contrary, so as to increase cutting edge supporting, energy
Enough it is prevented effectively from tipping.
In the present invention, nano ceramics scalpel positioning fixture is matched somebody with somebody using the flange on scalpel mounting groove and fixture
Close, realize positioning.Shape, the size of fixture upper flange change with the installation slot form of scalpel, therefore different scalpels will
There are different locating flanges.It is one of which shown in Fig. 2, turns to other forms when flange becomes, can also realize positioning.
In the present invention, it is the combination for leaning on sinetable and turntable that the motion of nano ceramics scalpel Fixture for sharpening, which is realized, it is illustrated that
Sinetable is homemade very simple one kind, and changing other sinetables into can also realize.The wedge that cutting edge Auxiliary support is used
Block, the cutting edge for having different forms, such as straight line sword according to cutting edge form and angle, voussoir need to be rectilinear form, arcuate blade
Cutting edge, according to the size of radian, the radian of corresponding adjustment voussoir, the voussoir shown in Fig. 4 is one of which.
