Abstract
Preferably, using inserted clamping, but nano-biological cerimic scalpel is very thin, only 0.3 0.5mm for traditional operation knife elasticity, toughness, and fragility is big, and toughness extreme difference is easily broken, and conventional damascene formula clamping is unsuitable for clamping nano-biological cerimic scalpel.To overcome the fixation problem between current ceramic scalpel blade and handle of a knife, the invention provides a kind of clamping handle of a knife of new nano-biological cerimic scalpel, that is clamped-in style clamping handle of a knife, handle of a knife includes long handle 1 and short handle 2, and the mounting groove 12 of blade 3 is provided with the leading section of long handle；The boss 4 with through hole is equipped with long handle 1 and short handle 2, is inserted in through hole and spring 6 is placed on fixing axle 5, axle 5, spring 6 is fixed between long handle 1 and short handle 2, makes its front end in contact condition；When needing to install blade, the afterbody of short handle only need to be pinned, its leading section and long handle is separated, blade is placed in mounting groove, then short handle is resetted, you can clamp.The scalpel of handle of a knife composition is easy to use, can be widely applied in all kinds of operation techniques.
Description
Technical field
The invention belongs to medical instruments field.More particularly to a kind of design and manufacture of nano ceramics scalpel handle of a knife.
Background technology
In numerous operating theater instruments, scalpel, which is undoubtedly, uses most one kind.At present, the scalpel clinically commonly used
Most of piece is all made of using carbon steel material, although this scalpel can complete surgical cut substantially, but exist many
The shortcoming of metal material, such as poor biocompatibility, easily get rusty, rough surface, surface are electrically charged, sharpness is poor, these problems
Cause operative incision inflammatory reaction strong, influence wound healing.Cut surface can be avoided to go out using bioceramic manufacture scalpel
Blood is enlivened, and is shortened the hemostasis by ligation time, the edge of a knife is quickly healed, without obvious cut channel, in ophthalmology, department of plastic surgery, vascular surgery, micro-
The fields such as surgery, neurosurgery can be widely used.
Ceramic scalpel piece fragility is big, poor toughness, and certain difficulty can be produced when being installed with handle of a knife, conventional carbon is used
The inserted installation way of steel knife blade is easily caused ceramic tip and surface occurs and split to carry out the clamping of ceramic scalpel piece
Line is directly broken, and the processing technology of traditional operation blade is not appropriate for ceramic scalpel piece.
The content of the invention
The problem of being produced when being fixed to overcome between current ceramic scalpel blade and handle of a knife, the invention provides one kind just
In the ceramic scalpel Knife handle structure of handling.
To achieve the above object, change traditional inserted clamping for clamped-in style clamping, be characterised by：The handle of a knife includes length
Handle 1 and short handle 2, the mounting groove 1-2 of ceramic tip 3 is provided with the leading section of long handle 1；Two bands are equipped with long handle 2 and short handle 3
The boss 4 of through hole, is connected with each other by fixing axle 5, and spring 6 is placed with fixing axle 5, and spring 6 supports long handle 1 and short handle 2, made
It is in contact, so that clamping blade.
The present invention has following beneficial effect：
1st, the present invention is not on the basis of general surgery handle of a knife basic configuration is changed, and size and clamping part to handle of a knife are tied
Structure is transformed.It is fluted on ordinary carbon steel scalpel blade, and also need to carry out on blade when being loaded and unloaded it is appropriately curved, due to
The fragility of ceramics is big, if also carrying out the processing mode such as punching to ceramic tip, easily causes stress concentration, causes blade to break
It is broken.To improve the yield rate of blade, the processing of mill surface and tool sharpening etc. is only carried out to blade.
2nd, handle of a knife is made up of 4 parts, if a certain damage parts can directly change the part, it is not necessary to change whole knife
Handle, has saved maintenance cost.
3rd, the entirety of fixing axle is " T " shape, when being cut using scalpel, and butt end is above so that without in taper end portion
Processing screw thread can ensure that fixing axle will not come off downwards, reduce the manufacturing procedure of screw thread.
4th, handle of a knife is manufactured using titanium alloy, light weight, is cleaned, is sterilized repeatedly, surface is also unaffected, safety durable.
5th, the installation way of the scalpel is simple and convenient, and user does not need special training normally to use, and
The clamping device of the scalpel is rational in infrastructure, is easy to use.
Brief description of the drawings
Accompanying drawing 1 is scalpel global design figure.
Accompanying drawing 2 is long handle design drawing.
Accompanying drawing 3 is short handle design drawing.
Accompanying drawing 4 is fixed shaft design figure.
Accompanying drawing 5 is blade schematic diagram.
Embodiment
Embodiment one：Referring to the drawings, structure of the invention includes long handle and short handle, and the long handle front end is provided with installation
Groove and blade are engaged, and the boss with through hole is equipped with long handle and short handle, are inserted in through hole on fixing axle, axle and are placed bullet
Spring, spring is fixed between long handle and short handle, handle of a knife leading section is in contact condition under spring force.
Embodiment two：Illustrate present embodiment with reference to Fig. 3, the leading section inclined-plane of the short handle of present embodiment is provided with convex
Bar.Raised line is processed on inclined-plane, it is possible to increase the Spring pinch force that blade is subject to, be conducive to the fixation of blade, use scalpel
Come more stable.
Installation process：When needing to install blade, the afterbody of short handle only need to be pinned, its leading section and long handle is separated, will
Blade is placed in mounting groove, then resets short handle, you can is clamped, and is used safely.
Claims (6)
1. there is provided a kind of new nano-biological cerimic scalpel installation way, i.e. clamped-in style clamping, it is characterised in that：The knife
Handle includes long handle and short handle, and the mounting groove of blade is provided with the leading section of long handle；It is equipped with long handle and short handle with the convex of through hole
Platform, is inserted in through hole and spring is placed on fixing axle, axle, and spring is fixed between long handle and short handle, makes its front end in connecing
