Description
Technical field
The present invention relates to a kind of scalpel.More particularly, the present invention relates to a kind of disposable self-destroyed scalpel.
Background technology
Scalpel carries out operating indispensable instrument, and its safety is for most important operator and sufferer.Scalpel traditional at present comprises integrated metal scalpel, the scalpel of knife handle of metal and non-metallic blades pressing and disposable blade is installed to before use handle of a knife, after a procedure from the detachable scalpel that handle of a knife removes.Integrated metal scalpel cost is higher, the scalpel of knife handle of metal and non-metallic blades pressing and detachable scalpel can allow user suffer from expose blade or because of the bloodstain on blade cause pollute potential injury, and, when the scalpel of exposure is passed to colleague by surgeon, also easily sharp instrument injury occurs, the blade installation and removal of detachable scalpel are difficulty and the process of danger.
Summary of the invention
An object of the present invention is to address the aforementioned drawbacks, and the advantage will illustrated at least is below provided.
A further object of the invention is to provide the disposable surgical cutter that a kind of structure is simply convenient to install.
According to these objects of the present invention and other advantage, provide a kind of disposable self-destroyed scalpel, comprising:
Handle of a knife, adopt made of plastic, described handle of a knife front end is provided with the boss 2 establishing knife blade 9 for card, groove is provided with in the middle part of described handle of a knife, one end near described boss 2 in described groove is provided with the first projection 3 being connected to described handle of a knife 1, and described first protruding 3 is " V " font, " eight " font or " work " font draw-in groove;
Locked clamp 4, be located at described handle of a knife side, the inner surface that described locked clamp 4 is adjacent with described handle of a knife 1 is provided with and matches with described first projection 3 and second projection 5 that cannot exit after inserting described first projection 3, and described locked clamp 4 is provided with the 3rd projection 6 towards the front end of knife blade 9; And,
Broach shell 7, be sheathed on described handle of a knife front end, described broach shell 7 adopts two-piece type structure, described broach shell 7 to be assembled by physics by upper and lower broach shell plate 7.2 or is bonded, the inner surface of described upper slitter cage plate 7.1 is provided with the groove 8 matched with described 3rd projection 6, cannot exit after the described groove 8 of described 3rd protruding 6 insertion, described locked clamp 4 is connected with described broach shell 7, the other end of described broach shell 7 is provided with knife blade resigning hole, and the width of described knife blade resigning hole is greater than described knife blade 9 Breadth Maximum; Upper and lower broach shell plate 7.2 for two-piece type structure ensure that Mould Machining feasibility operation.
Wherein, described locked clamp 4, described handle of a knife 1 and described broach shell 7 mate each other, closely cooperate between described broach shell 7 and described handle of a knife 1, closely cooperate between described second protruding 5 and described groove; Before using, the described 3rd protruding 6 inserts in described groove 8, and described second projection 5 in groove slidably; After using, promote described broach shell and insert described first projection 3, surgical knife safety self-destruction to described handle of a knife 1 nose motion to described second protruding 5.Before using; broach shell drives locked clamp can slide along groove on handle of a knife 1; but due to size corresponding matching between three, therefore broach shell is not easily shaken easily or the effect such as gravity and sliding, and broach shell plays the effect of protection blade at insert periphery; during use; can slide backward by manpower effect broach shell, blade is exposed, after using; again by external force driven forward broach shell, slide to realize foremost locked.
Preferably, wherein, described first projection 3 comprises two arms tiltedly stretched out, and described two-arm forms the passage of " eight " font arrangement, and described two-arm is respectively the first oblique arm and the second oblique arm.It is in order to when between the second projection 5 is by two-arm that described first oblique arm and the second oblique arm arrange in " eight " font, first oblique arm and the second oblique arm have certain elasticity, when two-arm angle is excessive, then easily fracture, and when two-arm angle is too small, then easily make the second projection deviate from from first protruding 3.
Preferably, wherein, described second projection 5 comprises, front end, described front end is the one in arrowhead-shaped, V-shape, rhombus, T font or tee T structure, described front end needs by and is snapped in the passage of " eight " font arrangement, therefore the structure being applicable to snapping in all can adopt, and is not limited to above-mentioned listed several structure; Rear end, is connected with described front end by a linkage section, and both sides, described rear end are resisted against described groove inwall, to form close-fitting state between the second projection and described groove; Wherein, described linkage section is I shape or V-shape structure.

One end that described upper slitter cage plate 7.1 is connected with described locked clamp 4 is provided with supports block for hand push, is convenient to promote broach shell plate.
Described locked clamp 4 is all made of plastics with described broach shell 7, can effectively reduce costs.
Broach shell, locked clamp, knife blade 9 assemble on handle of a knife by assembler by disposable surgical cutter described herein before dispatching from the factory; the second projection 5 of locked clamp is made to snap in the groove 8 of upper slitter cage plate 7.1; and owing to ensureing broach shell and the slightly resistant slip on handle of a knife 1 of locked clamp, thus ensure available protecting knife blade 9 before use scalpel.When after use scalpel, user will promote broach shell and locked clamp, protruding stuck in the first projection by second, ensure that broach shell can not be return again and knife blade 9 is not exposed, thus when avoiding destroying recovery, knife blade 9 couples of contactees damage.
As mentioned above, according to the present invention, owing to be all made of plastics except the miscellaneous part of knife blade outer operation cutter and multiple male cooperation uses, therefore have that structure is simple, the feature of lower, the safe and reliable self-destruction of cost.
Technological merit:
1., be convenient to assembling, can batch automatic production be realized, reduce costs.
2., do not change doctor's use habit, use feel, some safe operating knife changes more profiles, use habit and feel is difficult to meet, some use spring structures, and spring exists fatigue, is difficult to mass production.
3., safety can accomplish 100% percussion safety self-destruct, can not there is the possibility of superinfection.
4. the pause voice prompt of slight comfortable feel " click click " is had when, percussion lock design one is run before not having to pull the trigger on blade holder, prevent doctor from pulling the trigger self-destruction because of carelessness, after using, there is significantly " click " slightly large sound during self-destruction, point out self-destruction.
Technical characteristic:
1., cap and protective cap two-piece type structure is pulled the trigger
2., percussion cap and handle of a knife percussion junction percussion cap firing position adopt V-type, diamond pattern, umbrella shape, T font, tee T structure, I-shaped, the V-type of handle of a knife junction employing.
3., percussion cap is connected employing V-shape, diamond pattern, umbrella-shaped structure, both sides employing I-shape construction with protective cap.
Although embodiment of the present invention are open as above, it is not restricted to listed in description and embodiment utilization.It can be applied to various applicable the field of the invention completely.For those skilled in the art, can easily realize other amendment.Therefore do not deviating under the general concept that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
