The specific embodiment
As shown in Figure 1, the present invention is made up of blade (A) and electronic handle of a knife (B) two parts, and blade (A) is connected on the power transmission shaft (2) through bayonet socket (1).Electronic handle of a knife (B) outward appearance is like the ball lip pencil; Its shell (14) is a plastic cement material; The front portion is provided with press button (16); Tail end connects the AC power cord (15) of 24V.50HZ, inlay respectively in its front-end and back-end be provided with the antifriction metal (AFM) material, there are the preceding slideway (3) and the rear slide (12) of square trunk in the transverse section.Power transmission shaft (2) is the elongated cube of attrition resistant nonmagnetic metal material; Its leading portion and back segment can be distinguished pro-slideway (3) and the interior linear reciprocation slip of rear slide (12) and can not rotate; The front portion of power transmission shaft (2) is provided with the block (5) of nonmagnetic metal material; Have a front spring (4) to be placed on the power transmission shaft (2) between pro-slideway (3) and the block (5), the rear end of power transmission shaft (2) rear spring (13) interior with being placed in rear slide (12) contacts mutually.Electric magnet a (6), electric magnet b (8), electric magnet c (10) are identical cylindric; Its periphery all is fixed on the inwall of shell (14); Coaxial spaced reciprocally, arrangement in the same way; The axis part of its iron core all has enough loose square trunk can supply power transmission shaft (2) to pass, and these three electric magnet are parallel in 24 volts the alternating current circuit, accept the control of press button (16) simultaneously.Armature a (7), armature b (9), armature c (11) are soft magnetic materials, all are cylindric, and axis part all has square hole firmly to overlap to fix on the power transmission shaft (2).When three electric magnet all do not have electric current to pass through; Front spring (4) and rear spring (13) all are in the natural length state; Between armature a (7) and the electric magnet a (6) that closes on, between armature b (9) and the electric magnet b (8) that closes on, the air gap of the 2mm that all keeps between armature c (11) and the electric magnet c (10) that closes on having an appointment; And the spacing between armature a (7) and the electric magnet b (8), between armature b (9) and the electric magnet c (10) is all more than 12mm; Like this when energising electric magnet b (8) to armature a (7), electric magnet c (10) to the suction of armature b (9) will be very a little less than, thereby it is moving to guarantee that armature a (7) is only inhaled by electric magnet a (6), armature b (9) is only inhaled moving by electric magnet b (8).
During use; After pressing the button the alternating current of 24 volts of switch (16) connections; When alternating current was in positive half cycle, electric magnet a (6), electric magnet b (8), electric magnet c (10) produced magnetic simultaneously, and the armature a (7) that will close on separately respectively, armature b (9), armature c (11) attract tractive simultaneously; The common power transmission shaft (2) that drives is to front slide, and front spring (4) is compressed and energy storage; In the time of near alternating current is in zero point, electric magnet sharply reduces the suction of armature, being compressed property front spring (4) then rebound power transmission shaft (2) passed slip backward; Rear spring (13) is compressed and energy storage; When alternating current got into negative half period, electric magnet a (6), electric magnet b (8), electric magnet c (10) produced magnetic once more simultaneously, and the armature a (7) that will close on separately respectively once more, armature b (9), armature c (11) attract tractive simultaneously forward; Add the lifting force of rear spring (13); The common power transmission shaft (2) that drives is once more to front slide, and so along with the alternate of alternating current, power transmission shaft (2) will be apace, move back and forth little amplitude; Thereby drive the blade (A) be attached thereto apace, move back and forth, realization is to the light incision or the separation of sharp property of skin or other tough and tensile tissues little amplitude.The main effect of front spring (4) and rear spring (13) is under non-power status, to guarantee three blocks of armature and keep certain distance (about 2mm) separately between the adjacent electromagnets; And in the process of operation of switching on, release ability and kicking motion with the bounce-back recovery through being compressed energy storage; Alleviate concussion, use more steadily with comfortable.
When the present invention switched on and uses, its blade (A) can be rendered as the cutter shadow, and this cutter shadow is longer slightly than the actual size of blade, and operator only needs this cutter shadow is treated as blade and used, just can guarantee to cut and organize safely, can not cut near its hetero-organization of accidental injury by mistake.On the other hand; Because the reciprocal rapid movement of blade; Operator only needs blade to apply very little pressure to get final product incised tissue; Thereby when making knife blade, just can make blade very small and exquisite (the special-purpose microknife of cosmetic surgery), no longer need as the general surgery blade, must have suitable width and intensity just is unlikely to be pressed down and to fracture, thereby when the execution cosmetic surgery, more have superiority.
Can find out from the above; The present invention is simple in structure; Through using three groups of miniature alternating electromagnet-armature groups to unite driving, be suitable for pointing the elongated pipe shape (ball lip pencil) that grips even guaranteed electronic handle of a knife made, also can guarantee to produce enough driving forces; The quick alternation characteristic of alternating current has guaranteed that the reciprocating high frequency of blade is quick.Use this electric operation cutter, can help operator to cut fast, lightly, accurately or the tough and tensile tissue of sharp property separation, obviously improve the efficient and the quality of operation, when carrying out cosmetic surgery, than the general surgery cutter tangible exquisite advantage is arranged especially.
