Detailed description of the invention
Be described in further detail the present invention below in conjunction with the drawings and specific embodiments, those skilled in the art can more clearly understand other advantages of the present invention and effect thus.
It should be noted that, the structure that Figure of description illustrates, ratio, size etc., only in order to coordinate detailed description of the invention, more clearly understand design of the present invention for those skilled in the art, and be not used to limit the scope of the invention.The adjustment of the modification of any structure, the change of proportionate relationship or size, when not affecting effect of the present invention and object reaches, all should still drop within protection scope of the present invention.For the ease of understanding, the relative position relation of each parts is described according to the Butut mode of Figure of description.
As shown in Figure 1, Figure 2 shown in a, Fig. 2 b and Fig. 3, the adjusting device of a kind of ultrasound knife of the present invention comprises a housing 1, be provided with a cavity volume 10 at housing 1 internal fixtion one piece of circuit board 2, a surface of circuit board 2 is towards cavity volume 10, in cavity volume 10, a button 5 is installed, button 5 is fixed with electroconductive elastic sheet 4, and on the surface of circuit board 2 towards cavity volume 10, be provided with the contact element 20 that can contact with electroconductive elastic sheet 4, there are two back-moving springs 6 outwards to withstand on button 5 from case inside, the head of button 5 is exposed from housing.Like this, when button 5 is pressed, time mobile in cavity volume 10, electroconductive elastic sheet 4 can slide on the surface of contact element 20, thus the control signal of telecommunication changed, ultrasound knife main frame, according to the change controlling the signal of telecommunication, correspondingly adjusts the output energy of ultrasound knife.
Contact element 20 can be such as a swept resistance, when electroconductive elastic sheet 4 slides on swept resistance, causes the change of resistance, thus provides a current signal changed or voltage signal to ultrasound knife main frame.
In a preferred embodiment of the invention, at housing 1 internal fixtion support member 3, support member 3 is in tubular, the cylindrical body of the rectangle in cross section being preferably, have good strength and stiffness, above-mentioned cavity volume 10 is just arranged in support member 3, moves wherein for holding button 5.Support member 3 is provided with spring lead 31, and one end of back-moving spring 6 is enclosed within spring lead 31, and the other end withstands on button 5, to act on button 5 an outside power, resets for making button 5 when finger loosens.See Fig. 3, button 5 is provided with the elastic card claw 51 extended internally, the end of elastic card claw 51 is provided with barb 52, and under push-button reset state, barb 52 is hooked on support member 3, button 5 is unlikely and deviates from from support member 3.
Further, support member 3 is also provided with circuit board fixing groove, foregoing circuit plate 2 is fixedly mounted in circuit board fixing groove.
Certainly, the mode that button is not limited to press is touched.The mode that such as button also can push is touched, and uses finger press button, makes it slide along surface of shell or rotate, thus drives electroconductive elastic sheet 4 to slide on the surface of contact element 20.
In an embodiment be more preferably of the present invention, described contact element is the first electrode and at least two the second electrodes that are arranged on circuit board 2 surface.First electrode 21 and the second electrode 22 are Electricity conductive plaster, by print or the mode such as welding is fixed on circuit board 2 towards on the surface of cavity volume 10.
In the present embodiment, carry out the different electrode of conducting by the movement of button, thus export the energy of different gear, the configuration of electrodes therefore on circuit board also can be optimized.As shown in Figures 4 to 7, first electrode 21 and the second electrode are divided into three rows on the circuit board 2, often row all extends along the direction of motion of button, wherein a row is the first electrode 21, the length of the first electrode 21 is longer, in the length range of the first electrode 21, is provided with two and ranked second electrode, as shown in Figure 4, three second electrodes 22a, 22c and 22e are arranged in a row along the direction of motion of button; Also have two second electrodes 22b, 22d to line up an other row along the direction of motion of button, this is the situation of five the second electrodes, and the quantity of certain second electrode both can be more, can minimumly be also two.As shown in Figure 7, first electrode 21 and two second electrodes 22a, 22b also line up three rows, often arrange an electrode.Accordingly, the resilient contact 41 on electroconductive elastic sheet 4 also has three, and it is corresponding that electrode arranged by each resilient contact 41 and one on circuit board, for above-mentioned first electrode of conducting and the second electrode.By arranging the arrangement mode of resilient contact 41 and electrode, can control electroconductive elastic sheet 4 in moving process with the conducting relation of each electrode, both can realize more energy grade, and make again button have suitable stroke, handled easily.
In one preferred embodiment of the invention, corresponding to two the second electrodes of adjacent gear positions, at button 5(or electroconductive elastic sheet 4) moving direction on there is the overlapping region with electroconductive elastic sheet simultaneously conducting, composition graphs 8, Fig. 9 are described as follows.
As shown in Figure 8, each bar broken line P be represented by dotted lines
0, P
1, P
12p
5representative shows that each resilient contact on electroconductive elastic sheet is with the diverse location in button moving process.At P
0position, electroconductive elastic sheet does not all contact with each electrode, the therefore non-conducting of electrode, and ultrasound knife cutter head noenergy exports; When finger presses button, electroconductive elastic sheet is made to arrive P
1during position, electroconductive elastic sheet contacts with the first electrode 21 and the second electrode 22a simultaneously, and now the energy output grade of cutter head is the 1st grade; Further pressing button, makes electroconductive elastic sheet arrive P
12during position, electroconductive elastic sheet contacts with the first electrode 21, second electrode 22a, the second electrode 22b simultaneously, namely the second electrode 22a and the second electrode 22b has an overlapping region herein, this overlapping region can ensure can not be out of stock when gear switch, or meticulousr adjustment grade can be realized, according to the change in electric that electroconductive elastic sheet and electrode contact produce, main frame can make the energy output grade of now cutter head become the 2nd grade or a middle gear; Electroconductive elastic sheet moves inward further, arrives P
2during position, electroconductive elastic sheet only contacts with the first electrode 21, second electrode 22b, and now the energy output grade of cutter head is the 2nd grade; The like, button can be pressed further, obtain higher output energy grade.
Fig. 9 shows the process that above-mentioned output energy grade is progressively shifted gears.
As shown in Figure 10, above-mentioned adjusting device is arranged on cutter head 100, and is connected with ultrasound knife main frame 300 by wire.When using ultrasound knife, operator is when grasping handle, and a finger can just in time be buckled on button 5, when needs output energy carries out cutting bleeding operation, operator only needs as required, with the pressing of different dynamics button 5, the i.e. energy of exportable different gear; If operator loosens button completely, then push-button reset is to initial 0 file location, no longer includes energy output.
Certainly, above is only embody rule example of the present invention, does not constitute any limitation protection scope of the present invention.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
