Description

With the zirconium dioxide is the material of base, is the surgical cutting instrument that basic material is made by zirconium dioxide, is the instrument that basic material is made by zirconium dioxide
FIELD OF THE INVENTION
The present invention relates to medical devices, especially relating to the zirconium dioxide is the material of base, is the surgical cutting instrument made of material of base by zirconium dioxide, and is the instrument that the material of base is made by zirconium dioxide.
Prior art
Known have a kind of with stabilized with yttrium oxide with the zirconium dioxide be the base material (for example referring to Green, D.J., Hannink, R.H.J. and Swain, M.V. " conversion of pottery is toughness reinforcing " (TransformationToughening of Ceramics), CRC Press, Inc., Boca Ration, Florida, 1989.J), it is a kind of polycrystalline material, comprises magnesium, calcium and yttric oxide as stabilization additives.Described material is characterised in that its bending strength is 430-980MPa, and damaging viscosity (stress intensity coefficient) is 5.8-9.0MPam 1/2
A shortcoming of this material is to have crystal grain boundary in described material, and this just can not make it close with grain size is cutting edge acutance (cutting edge sharpness)≤high-quality of 1 μ m, attrition resistant cutting tool.
Known have a kind of with stabilized with yttrium oxide with the zirconium dioxide be the base monocrystal material (for example referring to Savage, J.A. " preparation and the performance that are used for the hard crystalline material of optical applications " (Preparation andProperties of Hard Crystalline Materials for Optical Application)-commentary, J.Cryst.Growth, 1991,113 volumes, 708 pages), it comprises the ZrO of 88 moles of % 2Y with 12 moles of % 2O 3Described material is characterised in that its microhardness is 1100-1400kg/mm 2, bending strength is 200-330MPa.
The shortcoming of this material is that intensity is low and wearability is not enough, and this is because its fragility is higher.
Known have a kind of with stabilized with yttrium oxide with the zirconium dioxide be the base material, it comprises at least a mixed oxide (for example referring to British patent No.1373888, IPC 04 B35/50,35/48), described mixed oxide comprises 10-20 mole %Y 2O 3With the painted mixed oxide of 0.01-5 weight %.Described material is characterised in that its microhardness is 1200-1300kg/mm 2
A shortcoming of this material is that its wearability is not enough, and this is because its fragility is higher.
Known have a kind of with stabilized with yttrium oxide with the zirconium dioxide be the base material (for example referring to Marscher, G.N., Pirouz, P. and Heuer, " hardness of the zirconium oxide monocrystalline of stabilized with yttrium oxide and the relation of temperature " of A.N. (Temperature Dependence of Hardness in Yttria-StabilizedZirconia Single Crystals), J.Am.Ceram.Soc., 1991,74 volumes, 491 pages), it comprises 90.5 moles of %ZrO 2With 9.5 moles of %Y 2O 3Described material is characterised in that its microhardness is 1400-1500kg/mm 2, crooked and compressive strength is 200-330MPa.
The shortcoming of this material is that crystalline size is little, and intensity is low and wearability is not enough, and this is because its fragility is higher.
With the immediate prior art material of material of the present invention be with yittrium oxide partially stabilized with the zirconium dioxide be the base material (for example referring to G.A.Gogotsi, E.E.Lomonova, " intensity of crystal of zirconium oxide and the fracture toughness " of V.G.Peichev (Strength and Fracture Toughness of ZirconiaCrystals), J.Eur.Ceram.Soc., 11 volumes, the 123-132 page or leaf, 1993), it comprises 97 moles of %ZrO 2With 3 moles of %Y 2O 3Described material is characterised in that its bending and compressive strength are 500-800MPa, and damaging viscosity (stress intensity coefficient) is 5-16Mpa 1/2
The shortcoming of this material is that wearability is not enough, and this is because its bending strength is lower, and damages the wide ranges of viscosity number, and this is because the microstructure and the phase composition of described material are inhomogeneous.
For the biological tissue in the open surgical methods uses disposable steel knife usually, it provides with the form of aseptic packaging, just be fixed on the support handle before using.
Term " disposable " has actual implication again to described cutter is existing in form, and this is because their rusts get very soon, and once must use several cuttings of disposable cutter being finished complexity in the operation.
The shortcoming of this cutter is conspicuous.At first, it is inconsistent being used for the rustless steel of steel edge and dissecting knife and the tissue of live organism, is repelled by it.Can form microthrombus like this, thereby cause blocking tiny blood vessel.
The second, the passivation of steel knife is a physical/chemical process, and this process can cause introducing in metal superfine (or bigger) granule and metal and lymph and the blood product of chemical reaction between the corrosive atmosphere in human body, thereby causes the complexity of various post processings.
The 3rd, because the cutter rust gets very fast and needs to change one new cutter, surgical touch feeling will change, thereby cause tissue is carried out unmanageable cutting.
The 4th, stainless physical arrangement make it can not reach high-quality cutting required less than 1 micron cutting edge acutance.And process technology makes cutting edge be the shape of " sawtooth " shape.Obvious distortion and wound when all these all can cause cutting and organizing.Tissue can crushed and damage.
Known have a kind of surgical cutting instrument (for example referring to Russ P 2053718), it comprises a handle of a knife and the blade that links to each other with described handle of a knife, described blade is to be made by the pottery that is base with the aluminium oxide, this operation blade is connected on the handle of a knife securely by fastener material, and it is that basic polycrystalline ceramics make by the Alpha-alumina that is 0.1-3.0 μ m with the particle mean size.
A shortcoming of this instrument is that its operation blade is only with an angle sharpening, will cause friction bigger in cutting process like this, needs with bigger dissection power, makes the tissue that is cut produce bigger distortion and wound.And, obtain its characteristic size less than the i.e. wear-resisting cutting edge of 3 μ m of the maximum particle size of the polycrystalline ceramics of making the operation blade, in fact also impossible.
Known have a kind of surgical cutting instrument (dissecting knife), and it comprises cutter, and this cutter has handle and is used to rigidly fix the knife rest (for example referring to Russ P 2005426) of cutter.On described support, have vertical end slot and slit.This vertical end slot and its corresponding cutter are made the trapezoid cross section, and this cutter is made with pottery.
A shortcoming of this cutting tool is that this demountable cutter is that " compression " installs, so need partly apply tangible shear force to abutting against cutting edge and parallel with it cutter when installation or removal.This operation is if manual carrying out damages then can for usually operator's hands.And the sharp edges of trapezoidal device and angle can cause damage to the aseptic surgery glove, and after dissecting knife carried out disinfection, operator packed it in these glove.This cutting tool also has shortcoming, because cutter is to be made by the pottery with grain structure.For this reason, can not make in practice have required less than 1 μ m the cutting edge acutance and have the wear-resisting cutting tool on high quality operation surface.
