Description
Technical field
The utility model is related to medicine technology fields, and in particular to a kind of scissors knife card pathological material-drawing knife.
Background technology
Pathological sample sampling is the important step that pathological section makes, and traditional pathological material-drawing knife is trans- using right angle handle of a knife
Blade is caught in trans- knife card after clamping fixed and draws materials by the design of knife card, easy to operate, is that one kind being widely used in hospital's disease
Reason materials and the classical medical equipment of medical colleges and schools's teaching.
Traditional pathological material-drawing knife is designed using trans- knife card, and the centre of bottom has an empty slot, thickness to be no more than knife
Piece thickness, length, height are respectively less than the length and height of blade.In use, first blade is picked up with tweezers, by the one of blade back
End is caught in out of this empty slot, and then blade work portion, which is pressed on sampling platform, makes the big portion of blade be caught in empty slot, while by blade
Work department is adjusted to horizontality, is continued to be adjusted to suitable position with tweezers clamping blade, and blade work portion is only stayed to expose
For drawing materials outside empty slot.Operating procedure is more complex when traditional pathological material-drawing knife uses, and through use after a period of time
Knife card fluffs afterwards, and blade is easy to loosen, fall off, and influences pathologic sampling quality, speed, or even operator is caused to be hurt, greatly
Increase the risk of occupational exposure.In addition, the handle of a knife of traditional pathological material-drawing knife is in level angle with blade operative part, and people
Machine engineering science is the study found that handle of a knife is more comfortable in being held when 10 ° or so angles with blade.In addition, traditional pathological material-drawing knife
The design of right angle handle of a knife can not improve force state, and while exerting a force, is easy sliding, uses thumb, the index finger of rear operator for a long time
And wrist, arm stress aggravate, and are susceptible to the occupational injuries such as tenosynovitis, wrist trace integration disease and repeatability injury.
Utility model content
The purpose of the utility model is to overcome the drawbacks described above of the prior art, a kind of blade in use is provided always
In gripping orientation, and it is simple, convenient, use comfortable, safe scissors knife card pathological material-drawing knife.
To realize the above-mentioned technical purpose, a kind of scissors knife card pathological material-drawing knife provided by the utility model, including knife card and
Handle of a knife, it is characterised in that：The knife card is scissors knife card, and the handle of a knife is arc line shaped handle of a knife, and the scissors knife card is by passing through riveting
Nail association can be in that the fixing cutter card of scissor folding and movable blade card form；The knife card back of the fixing cutter card is thicker,
The knife card lower part of the fixing cutter card is relatively thin, and fixing cutter card described in the thickness official post of the two and movable blade engaging form one when holding together
Thickness is not less than the empty slot of blade thickness；The knife having on two sizes, spacing and the blade is set on knife card lower part
The protrusion of piece pocket matches, the protrusion is not less than the thickness of the empty slot towards the height that the movable blade card convex goes out, in institute
State on movable blade card that there are two arch bayonets with the raised corresponding position；At the closely described arc line shaped handle of a knife in movable blade card surface
Being provided with to push can make the fixing cutter card and movable blade card be in the button that scissor is opened.
Preferably, the angle of the blade working portion of the handle of a knife axis and blade of the arc line shaped handle of a knife is 10 °.
It is further preferred that the front end of the arc line shaped handle of a knife is provided with thrust structure.
The beneficial effects of the utility model：The utility model is designed using scissors knife card, simple, convenient, and energy
Ensure that in use, blade is in gripping orientation always, not only extends service life, but also effectively reduce operator
The risk of occupational injury and exposure, it is safe to use；Arc line shaped handle of a knife design, with hand coincide, the axis of this out circle handle of a knife with
The angle of blade working portion is in 10 °, is more in line with Human Engineering Principle, and applicability enhancing holds comfortable, arc line shaped handle of a knife
Front end is thrust structure, convenient for force, prevents axial slippage, stability is strong, easy to spread.
