Detailed description of the invention
Being described in further detail the present invention with detailed description of the invention below in conjunction with the accompanying drawings, those skilled in the art are thus
Other advantages and effect of the present invention can be more clearly understood.
It should be noted that structure depicted in Figure of description, ratio, size etc., only in order to coordinate specific embodiment party
Formula, more clearly understands the design of the present invention, and is not used to limit the scope of the invention for those skilled in the art.Any
The modification of structure, the change of proportionate relationship or the adjustment of size, in the case of the effect and purpose not affecting the present invention is reached,
All should still fall within the scope and spirit of the invention.In order to make it easy to understand, the relative position relation of each parts is according to description
The Butut mode of accompanying drawing is described.
As shown in Figure 1, Figure 2 shown in a, Fig. 2 b and Fig. 3, the adjusting means of a kind of ultrasound knife of the present invention includes a housing 1, at shell
Fixing one piece of circuit board 2 in body 1 and be provided with a cavity volume 10, a surface of circuit board 2, towards cavity volume 10, is installed in cavity volume 10
One button 5, button 5 is fixed with electroconductive elastic sheet 4, and at circuit board 2 towards be provided with on the surface of cavity volume 10 can be with conduction bullet
The contact element 20 that sheet 4 contacts, has two back-moving springs 6 outwards to withstand on button 5 from case inside, makes the head of button 5
Expose from housing.So, when button 5 is pressed, and moves in cavity volume 10, electroconductive elastic sheet 4 can be at the table of contact element 20
Sliding on face, thus produce the control signal of telecommunication of change, ultrasound knife main frame, according to the change of the control 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 resistance
The change of value, thus provide a current signal changed or voltage signal to ultrasound knife main frame.
In a preferred embodiment of the invention, fixing a support member 3 in housing 1, support member 3 is in tubular,
The cylindrical body of the good rectangle being in cross section, has preferable strength and stiffness, above-mentioned cavity volume 10 to be just arranged in support member 3, uses
Move wherein in accommodating button 5.Being provided with spring lead 31 on support member 3, one end of back-moving spring 6 is enclosed within spring and guides
On post 31, the other end withstands on button 5, acts on an outside power on button 5, for making button 5 multiple when finger loosens
Position.Seeing Fig. 3, be provided with the elastic card claw 51 extended internally on button 5, the end of elastic card claw 51 is provided with barb 52, at button
Under reset state, barb 52 is hooked on support member 3, makes button 5 be unlikely from support member 3 abjection.
Further, support member 3 being additionally provided with circuit board fixing groove, foregoing circuit plate 2 is fixedly mounted on circuit board and fixes
In groove.
Certainly, button is not limited in the way of pressing be touched.The mode that such as button can also push is touched, and uses
Finger press button so that it is slide along surface of shell or rotate, thus drive electroconductive elastic sheet 4 sliding on the surface of contact element 20
Dynamic.
In an embodiment more preferably of the present invention, described contact element is be arranged on circuit board 2 surface
One electrode and at least two the second electrode.First electrode 21 and the second electrode 22 are Electricity conductive plaster, by sides such as printing or welding
Formula is fixed on circuit board 2 towards on the surface of cavity volume 10.
In the present embodiment, turn on different electrodes by the movement of button, thus export the energy of different gear, because of
Configuration of electrodes on this circuit board can also optimize.As shown in Figures 4 to 7, the first electrode 21 and the second electrode are at circuit
Being divided into three rows on plate 2, often row all extends along the direction of motion of button, and wherein a row is the first electrode 21, the first electrode 21
Length 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 the second electrode 22a,
22c and 22e is arranged in a row along the direction of motion of button；Two second electrodes 22b, 22d are also had to line up along the direction of motion of button
An other row, this is the situation of five the second electrodes, and the quantity of certain second electrode both can be more, it is also possible to minimum is two.
As it is shown in fig. 7, first electrode 21 and two second electrodes 22a, 22b also line up three rows, often one electrode of row.Accordingly,
Resilient contact 41 on electroconductive elastic sheet 4 also has three, and each resilient contact 41 is corresponding with the row's electrode on circuit board, is used for
Turn on above-mentioned first electrode and the second electrode.By arranging the arrangement mode of resilient contact 41 and electrode, conduction bullet can be controlled
Sheet 4 in moving process with the conducting relation of each electrode, both can realize more energy grade, and make again button have suitable row
Journey, convenient operation.
In one preferred embodiment of the invention, corresponding to two the second electrodes of adjacent gear positions, at button 5(or lead
Electricity shell fragment 4) moving direction on there is the overlapping region simultaneously turned on electroconductive elastic sheet, be described as follows in conjunction with Fig. 8, Fig. 9.
As shown in Figure 8, each bar broken line P being represented by dotted lines0、P1、P12……P5Represent each elasticity showing on electroconductive elastic sheet to touch
Point is with the diverse location in button moving process.At P0Position, electroconductive elastic sheet does not contacts with each electrode, and therefore electrode is not led
Logical, ultrasound knife cutter head noenergy exports；When finger presses button, electroconductive elastic sheet is made to arrive P1During position, electroconductive elastic sheet simultaneously with
First electrode 21 and the second electrode 22a contacts, and now the energy output level of cutter head is the 1st grade；Press button further, make
Electroconductive elastic sheet arrives P12During position, electroconductive elastic sheet contacts with first electrode the 21, second electrode 22a, the second electrode 22b simultaneously,
Namely the second electrode 22a and the second electrode 22b has an overlapping region herein, and this overlapping region can ensure that and cuts at gear
Will not be out of stock when changing, or finer regulation grade can be realized, according to telecommunications produced by electroconductive elastic sheet and electrode contact
Number change, main frame can make the energy output level of now cutter head become the 2nd grade or a middle gear；Electroconductive elastic sheet is further
Move inward, arrive P2During position, electroconductive elastic sheet only contacts with first electrode the 21, second electrode 22b, the now energy of cutter head
Output level is the 2nd grade；The like, button can be pressed further, it is thus achieved that 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 means is arranged on cutter head 100, and is connected with ultrasound knife main frame 300 by wire
Connect.When using ultrasound knife, operator is when grasping handle, and a finger can just be buckled on button 5, when needs are defeated
Going out energy when carrying out cutting bleeding operation, operator only needs as required, presses button 5 by different dynamics, the most exportable not
Energy with gear；If operator loosens button completely, then push-button reset is to initial 0 file location, no longer has energy to export.
Certainly, above is only the concrete exemplary applications of the present invention, does not constitutes any limitation protection scope of the present invention.Remove
Outside above-described embodiment, the present invention can also have other embodiment.The technical side that all employing equivalents or equivalent transformation are formed
Case, within all falling within scope of the present invention.
