Technical field
This utility model belongs to medical instruments field, particularly relates to a kind of scalpel for medical surgery operation and knife blade.
Background technology
Scalpel is a kind of very important instrument in medical surgery operation, and it is that the healthy cause of the mankind provides strong guaranteeing role.Scalpel comprises blade and handle of a knife substantially, and blade is generally made up of metal material.
The most frequently used in metal material is rustless steel, and the blade work in-process of rustless steel scalpel there will be broached-tooth design, although this broached-tooth design is very trickle and naked eyes are difficult to identification, the surgical site infections using this scalpel to carry out easily causes cicatrix to generate.In addition, there is the risk of metallic element diffusion in the scalpel that metal material is made, thus contaminated wound.Further, the service life of the scalpel that metal material is made is shorter, needs periodic replacement, adds the cost consumption of medical institutions undoubtedly.
Summary of the invention
In view of the scalpel Problems existing that prior art metal material is made, the first object of the present utility model is to provide a kind of knife blade, and another object of the present invention is to provide a kind of scalpel.
In order to realize the purpose of this utility model, the knife blade that this utility model provides comprises main part; The knife back, the knife back is the first edge part of main part; Blade; Blade extends to form in the Second Edge edge of main part; Knife blade is made up of zirconia ceramics, and main part has cutter afterbody, and cutter afterbody has protruding circular arc, and the central region of cutter afterbody has circular hole.
Such scheme is visible, the knife blade be made up of zirconia material, can not produce jagged blade in machine-shaping process, and when surgical operation, the diffusion of metallic element does not occur, and is longer than the knife blade of metal material service life; In addition, when knife blade adopts the mode of direct injection moulding to be connected with plastic handle, cutter tail protrusion circular arc can prevent blade from being pulled out by force under external force, and, the afterbody of blade devises the benchmark circular hole for locating, for the location of blade when injection molding handle of a knife.
A preferred scheme is that the knife back is parallel with the length direction of knife blade, and the knife back is linear structure.
Such scheme is visible, and linear knife back structure not only simplify blade shapes, and is conducive to the location of blade in grinding; In addition, when the handle of a knife injection moulding process of knife blade, can position with the linear structure of the knife back.
A preferred scheme is, blade is made up of large sword and little sword, and large sword, between main part and little sword, reprocesses little sword after large sword processes.
Such scheme is visible, knife blade opens the design of large sword and little sword, effectively can ensure the sharpness of blade, both sides are adopted to open after large sword surface press finishing again in production, last essence again opens little sword, thus ensures that the sharpness of knife blade is higher, at present, the sharpness of the Standard scalpel of metal scalpel is 0.8N, and the knife blade sharpness that this utility model provides is between 0.25N to 0.4N.
A preferred scheme is, cutter tail protrusion circular arc and blade junction have transition arc.
Such scheme is visible, effectively prevents the stress of knife blade in molding and sintering from concentrating.
A preferred scheme is, the surface of knife blade adopts tumbling PROCESS FOR TREATMENT, and main part has the mark produced by laser etching process.
Such scheme is visible, blade face after polishing, roughness Ra between 0.04 to 0.1 μm, higher than the Ra0.4 μm of GB standard; The mark of knife blade top cutter model adopts the technique of laser ablation, more attractive in appearance than metal scalpel impression writing, and does not almost have indenture, can not hide to receive bloodstain or body fluid.
A preferred scheme is, the cutting edge angle of the nose part of knife blade is 6.7 ° to 7.7 °, and the end of nose part has turning, and the blade angle of corner is 23 ° to 25 °.
Such scheme is visible, and through repeatedly testing, the angle of nose part is that the knife blade of 6.7 ° to 7.7 ° is suitable for using as surgical operation, and the end of the nose part of knife blade has turning, and the angle at turning is 23 ° to 25 °.
A preferred scheme is, the thickness of main part is 0.65 millimeter to 0.700 millimeter, in addition, thickness is that the knife blade of 0.695 to 0.700 millimeter is suitable for processing and is suitable for operating application, this utility model provides scalpel to comprise knife blade, knife blade comprises main part, the knife back and blade, and the knife back is the first edge part of main part, and blade extends to form in the Second Edge edge of main part; Handle of a knife, knife blade is fixed on handle of a knife; Knife blade is made up of zirconia material; Main part has cutter afterbody, and cutter afterbody has protruding circular arc, and the central region of cutter afterbody has circular hole.
A preferred scheme is, handle of a knife parcel circular hole.
