Detailed description of the invention
Traditional scalpel mostly is straight type structure due to it, and in operation process, Chang Buneng is conveniently used for excision deep layer focus.And some are with angled scalpel, because angle is fixing, versatility is too poor.Consider that scalpel is as apparatus important in operation process, require that its structure is simple, easy to use, give the scalpel that a kind of angle can conveniently regulate in this programme:
A scalpel for variable-angle, comprises blade 1 and handle of a knife 5, and described handle of a knife 5 front end is hinged with the cutter head 2 for installing blade 1, handle of a knife 5 is provided with chute 8, be equipped with push button 7 in chute 8, push button 7 is connected with cutter head 2 by link gear 11, and push button 7 can be fixed relative to handle of a knife 5.
Different from traditional scalpel structure, the cutter head 2 arranged in handle of a knife 5 front end in this programme is for carrying out the mechanism of plug-in mounting cooperation with blade 1, combining easily from different cutter heads 2.Cutter head 2 is hinged on handle of a knife 5 front end by rotating shaft 3, before the use, or in use procedure, the angle of blade 1 is changed as needed, only need to utilize link gear 11 to control the angle of cutter head 2 by the push button 7 on rear end handle of a knife 5, handle of a knife 5 angle is adjusted, and also just have adjusted the angle of blade 1.The maximum benefit of this adjustment mode can probe at scalpel the adjustment carrying out blade 1 angle after in body again, and first need not adjust blade 1 angle, comparatively speaking more practical.Link gear 11 can adopt various mechanism, can be the mechanism of circular motion by transform linear motion.After adjusting the position of blade 1, push button 7 is fixed on handle of a knife 5.When again needing adjustment angle, remove after relatively fixing and utilize push button 7 to adjust the angle of blade 1 again.
Consider the simplification of structure, in this programme, propose a kind of link gear:
Link gear is arranged on that handle of a knife 5 is inner, and comprise the push rod 111 be connected with push button 7 by card column 10, push rod 111 front end is arranged on a rotating cylinder 113 by throw-out collar 114, and rotating cylinder 113 movable be sleeved on be arranged at handle of a knife 5 interior forward end fixed leg 12 on; Rotating cylinder 113 is fixedly installed bull stick 112, bull stick 112 is connected with cutter head 2.
As shown in Figures 4 to 6, link gear is formed primarily of push rod 111 and bull stick 112, and push rod 111 is connected by card column 10 with push button 7, and adopts hinged mode between card column 10 and push rod 111.Card column 10 has two effects, and first transmitting thrust makes the angle of cutter head 2 change as required, and it two is that the position of cutter head 2 is fixed.
See Fig. 4, be provided with axially along the fixed leg 12 of handle of a knife 5 thickness direction in inside, handle of a knife 5 front end, fixed leg 12 is set with the rotating cylinder 113 that an energy rotates around fixed leg 12.Rotating cylinder 113 is arranged one section of bull stick 112, bull stick 112 adopts fixed form to be connected with rotating cylinder 113, and bull stick 112 other end is connected with cutter head 2, is so just connected in order to integral structure with rotating cylinder 113 by cutter head 2.As shown in Figure 5, push rod 111 rear end and card column 10 hinged, a throw-out collar 114 is installed in front end, rotating cylinder 113 is made a call to a hole, is sleeved on hole by throw-out collar 114.This hole is equivalent to rotating cylinder 113 circumferentially a bit, when push rod 111 is exerted a force to rotating cylinder 113 by throw-out collar 114, rotating cylinder 113 rotates, and rotating cylinder 113 and cutter head 2 are fixedly connected with by bull stick 112, dynamic cutter head 2 is with to rotate, to realize the function of cutter head 2 angular adjustment when rotating cylinder 113 rotates.
Cutter head 2 angle adjustment well after, need to be fixed its position.Cutter head 2, when being subject to external force and hindering, can produce the trend that rotating cylinder 113 is rotated.When rotating cylinder 113 rotates, on rotating cylinder 113, any point position can change.Conversely, for any point on rotating cylinder 113, as long as keep the invariant position of this point, also with regard to making rotating cylinder 113, the position of cutter head 2 obtains fixing.
This point can be regarded as above-mentioned hole, and hole is connected with push rod 111 by throw-out collar 114, and push rod 111 is connected with push button 7 by card column 10, and so how this problem of position of fixing hole is just transformed to the position how fixing push button 7.
Chute 8 is provided with multiple setting perpendicular to chute 8 and the draw-in groove 9 through with chute 8, card column 10 may be stuck in draw-in groove 9.
As shown in Fig. 1 Fig. 2, draw-in groove 9 and the through setting of chute 8, after push button 7 drives card column 10 to slide in chute 8 to adjust cutter head 2 position, push button 7 is pushed to draw-in groove 9 side, card column 10 is made to snap in a draw-in groove 9, fixing with regard to making the position of push button 7 obtain, also namely secure the position of cutter head 2.In order to there be better fixed effect, rubber layer can be set with in card column 10, increase the friction between card column 10 and draw-in groove 9, preventing the situation of deviating from.
When doctor grips scalpel, thumb, by handle of a knife 5, when handle of a knife 5 being infected with blood etc., has easily skidded in operating process.On handle of a knife 5 outer surface, be provided with concave surface 6 in this programme, in concave surface 6, be provided with burr, when thumb is pressed in concave surface 6 during operation, good anti-skidding effect can be played.Handle of a knife 5 outer surface is provided with the anti-slip veins 4 of diagonal, also can plays auxiliary anti-slipping effect.
When carrying out deep operations for needs scalpel, surgical field of view is poor, therefore on scalpel, optionally can be added with lighting mechanism in this programme.
Lighting mechanism comprises installing plate 14, offers the groove 15 coordinated with handle of a knife 5 in the middle part of installing plate 14, and lighting mechanism is arranged on handle of a knife 5 by groove 15; A face of installing plate 14 is evenly distributed with LED 13, another face is provided with battery compartment 16.
Lighting mechanism compact structure, can be enclosed within handle of a knife 5 conveniently by groove 15, and the position to adjust lighting mechanism of sliding.A face is provided with the high LED of brightness 13 to lighting mechanism, can when adjusting scalpel position for visual area provides bright light.Lighting mechanism can add when needed, also can add after scalpel position is adjusted again.The power supply of LED 13 is provided by the button cell be arranged in the battery compartment 16 at installing plate 14 back, and this battery also can be convenient for changing.In order to make relative sliding not to occur between installing plate 14 and handle of a knife 5, the sidewall of groove 15 being provided with elastic layer, increasing the frictional force between groove 15 and handle of a knife 5.
