Brief description of the drawings
Fig. 1 is the cross-sectional schematic of the adjustable treatment of action length of the present invention electrode tip.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated, wherein, direction of the present invention is taking Fig. 1 as standard.
As shown in Figure 1, the treatment that action length of the present invention is adjustable comprises insulation shell 1 with electrode tip, several metal electrode pins 2, holder 3, power supply terminal 4, telescoping mechanism 5 and electrode needle cover 8, in housing 1, be formed with cavity 11, cavity 11 extends and runs through (being that its left end is opening setting) to left end, electrode needle cover 8 is arranged on the left end opening part of housing 1, electrode needle cover 8 is formed with respectively pin hole 81 corresponding to the position of each electrode needle 2, all electrode needle 2 are fixed on holder 3, and all electrode needle 2 are left and right directions and be arranged in parallel, holder 3, telescoping mechanism 5 and power supply terminal 4 are installed in cavity 11, power supply terminal 4 is electrically connected all electrode needle 2, the two ends of power supply terminal 4 can contact conducting with external power source respectively, telescoping mechanism 5 drives holder 3 to drive all electrode needle 2 to make left and right linear reciprocating motion along cavity 11, and under the driving of telescoping mechanism 5, each electrode needle 2 can be stretched out electrode needle cover 8 along corresponding pin hole 81.Like this, the length that can be changed electrode needle 2 and stretched out electrode needle cover 8 by telescoping mechanism 5, makes the electrode tip of the present invention can be according to patient's the depth of interaction that need to change at any time electrode needle 2, to reach better treatment assosting effect, simple in structure, easy to operate, versatility is also stronger.
Wherein, telescoping mechanism 5 can adopt gear length adjustment or other adjustment structure, be fixedly connected with holder 3 by the actuating rod of a left and right directions setting, alignment pin is set on actuating rod, the length difference of stretching out electrode needle cover 8 according to electrode needle 2 on housing 1 arranges different gear grooves, such as, when selecting gear for the moment, represent that it is 1 millimeter that electrode needle 2 is stretched out the length of electrode needle cover 8, in the time selecting gear two, represent that it is 3 millimeters that electrode needle 2 is stretched out the length of electrode needle cover 8, in the time selecting gear three, represent that it is 5 millimeters that electrode needle 2 is stretched out the length of electrode needle cover 8, by that analogy.
Telescoping mechanism 5 of the present invention is paid the utmost attention to employing following proposal: telescoping mechanism 5 comprises can be at the interior screw mandrel 52 of doing the reciprocating union joint 51 in left and right and left and right directions setting of cavity 11, union joint 51 is fixedly connected with holder 3, union joint 51 right-hand members are provided with the nut sleeve 53 with screw mandrel 52 interoperations, screw mandrel 52 is arranged in cavity 11 by bearing 54, on housing 1, be formed with and stir window 12, screw mandrel 52 parts are exposed to stirs in window 12, the outer wall that is exposed to the screw mandrel 52 of stirring this part in window 12 be formed with can be for operator's rotary screw rod 52 stir tooth 521.Like this, in the process of practical operation, operator drives screw mandrel 52 to rotate by stirring tooth 521, because screw mandrel 52 is to be arranged in cavity 11 by bearing 54, screw mandrel 52 is in the process of rotating, and because nut sleeve 53 is in the cooperation of screw mandrel 52, the union joint 51 that is fixedly connected with holder 3 can move left and right along screw mandrel 52, like this, all electrode needle 2 will be done together left and right and moves back and forth along with holder 3.
Further, for auxiliary union joint 51 is better made left and right linear reciprocating motion, the present invention can also form left guide part 511 at the right-hand member of union joint 51, in the cavity 11 of housing 1, be formed with and the left guide ring 13 of left guide part 511 interoperations, the profile of the exterior contour of left guide part 511 and left guide ring 13 inwalls can be the stage bodies such as the left and right directions oval stage body, triangle stage body, cuboid or the changeable stage body that arrange.
Further, in order to prevent that screw mandrel 52 may be from the interior disengaging of nut sleeve 53 in the process of rotating, the left limit post 14 that the present invention can also can stop screw mandrel 52 and nut sleeve 53 to depart from completely in the interior formation of the cavity of housing 1 11, is formed with the left limit portion 512 with left limit post 14 interoperations on union joint 51.In the time that screw mandrel 52 is about to depart from nut sleeve 53, left limit portion 512 just props up left limit post 14, and union joint 51 just can not continue to left movement like this, and it has reached limit on the left position.
Further, the present invention also comprises that one can cover the protective cover 6 of stirring window 12 completely, and protective cover 6 can entangle the right-hand member of housing 1, and closely cooperates with the outer wall of housing 1.Like this, by after stirring tooth 521 and determining electrode needle 2 and stretch out the length of electrode needle cover 8, cover protective cover 6, can avoid, in the process using, changing the depth of interaction of electrode needle 2 because of the effect of external force, affect patient's treatment and rehabilitation.
Further, the right-hand member of screw mandrel 52 of the present invention is formed with the screw 71 of left and right directions, in cavity 11, being provided with can be at the interior reciprocating connecting rod 72 in left and right of doing of cavity 11, the left end of connecting rod 72 is formed with the external screw thread coordinating with screw 71, and the outer wall of connecting rod 72 is formed with the dimension line that can feedback link bar 72 moves left and right distance.Like this, because connecting rod 72 is associated with moving left and right of union joint 51, when the structure of screw thread of nut sleeve 53 and the structure of the screw thread of screw 71 are when consistent, connecting rod 72 is identical with the distance moving left and right of union joint 51, like this, length that can accurate localizing electrode pin 2 stretches out electrode needle cover 8 by the dimension line on connecting rod 72, designs more accurately, and the effect of the auxiliary treatment of electrode tip of the present invention also can be better.Wherein, for auxiliary connecting rod 72 is better made left and right linear reciprocating motion, the outer wall of connecting rod 72 of the present invention forms right guide part 721, in cavity 11, be provided with and the right guide ring 15 of right guide part 721 interoperations, the profile of the exterior contour of right guide part 721 and right guide ring 15 inwalls can be the stage bodies such as the left and right directions oval stage body, triangle stage body, cuboid or the changeable stage body that arrange.
The foregoing is only preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, in implementation process, may there is local small structural modification, if various changes of the present invention or modification are not departed to the spirit and scope of the present invention, and within belonging to claim of the present invention and equivalent technologies scope, the present invention is also intended to comprise these changes and modification.
