Description of drawings
Fig. 1 is the cross-sectional schematic of the adjustable treatment of action length of the present invention with electrode tip.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further set forth, wherein, direction of the present invention is standard with Fig. 1.
As shown in Figure 1; The treatment that action length of the present invention is adjustable comprises insulation shell 1, several metal electrode pins 2, holder 3, power supply terminal 4, telescoping mechanism 5 and electrode needle cover 8 with electrode tip, is formed with cavity 11 in the housing 1, and cavity 11 is to the left end extension and run through (being that its left end is the opening setting); Electrode needle cover 8 is installed in the left end opening part of housing 1; Electrode needle cover 8 is formed with pin hole 81 respectively corresponding to the position of each electrode needle 2, and all electrode needle 2 are fixed on the holder 3, and all electrode needle 2 are left and right directions and laterally arrange; Holder 3, telescoping mechanism 5 and power supply terminal 4 are installed in the cavity 11; Power supply terminal 4 is electrically connected all electrode needle 2, and the two ends of power supply terminal 4 can contact conducting with external power source respectively, and telescoping mechanism 5 drive fixing seats 3 drive all electrode needle 2 and can make left and right sides 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 the pin hole 81 of correspondence.Like this, can change the length that electrode needle 2 is stretched out electrode needle cover 8, make electrode tip of the present invention can change the depth of interaction of electrode needle 2 at any time according to patient's needs through telescoping mechanism 5; 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, and the actuating rod that promptly is provided with through a left and right directions is fixedly connected holder 3; Alignment pin is set on the actuating rod, and the length difference of on housing 1, stretching out electrode needle cover 8 according to electrode needle 2 is provided with different gear grooves, such as; When selecting gear for the moment, the length that expression electrode needle 2 is stretched out electrode needle cover 8 is 1 millimeter, when selecting gear two; The length that expression electrode needle 2 is stretched out electrode needle cover 8 is 3 millimeters; When selecting gear three, the length that expression electrode needle 2 is stretched out electrode needle cover 8 is 5 millimeters, by that analogy.
Further; For auxiliary union joint 51 is better made left and right sides linear reciprocating motion; The present invention can also form left guide part 511 at the right-hand member of union joint 51; Be formed with the left guide ring 13 with left guide part 511 interoperations in the cavity 11 of housing 1, the profile of the exterior contour of left guide part 511 and left guide ring 13 inwalls can be the stage bodies such as oval stage body, triangle stage body, cuboid or changeable stage body that left and right directions is provided with.
Further; In order to prevent that screw mandrel 52 possibly break away from nut sleeve 53 in rotating process; The present invention can also be in the cavity 11 of housing 1 the formation left limit post 14 that can stop screw mandrel 52 and nut sleeve 53 to break away from fully, be formed with left limit portion 512 on the union joint 51 with left limit post 14 interoperations.When screw mandrel 52 and nut sleeve 53 were about to break away from, left limit portion 512 just propped up left limit post 14, and union joint 51 just can not continue to left movement like this, and promptly it has reached the limit on the left position.
Further, the present invention comprises that also one can cover the protective cover 6 of stirring window 12 fully, 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,, cover protective cover 6, can avoid in the process of using, changing the depth of interaction of electrode needle 2 because of the effect of external force, influence patient's treatment and rehabilitation through after stirring tooth 521 and confirming that good electrode needle 2 are stretched out the length of electrode needle cover 8.
Further; The right-hand member of screw mandrel 52 of the present invention is formed with the screw 71 of left and right directions; Be equipped with in the cavity 11 and can in cavity 11, make the reciprocating connecting rod 72 in the left and right sides; The left end of connecting rod 72 is formed with the external screw thread that cooperates with screw 71, and the outer wall of connecting rod 72 is formed with the dimension line that can feed back connecting rod 72 move left and right distances.Like this; Because connecting rod 72 is associated with the move left and right of union joint 51, when the structure of the structure of the screw thread of nut sleeve 53 and the screw thread of screw 71 was consistent, connecting rod 72 was identical with the distance of the move left and right of union joint 51; Like this; The length that can stretch out electrode needle cover 8 through the accurate localizing electrode pin 2 of the dimension line on the connecting rod 72, design are accurate more, 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 sides linear reciprocating motion; The outer wall of connecting rod 72 of the present invention forms right guide part 721; Be provided with the right guide ring 15 with right guide part 721 interoperations in the cavity 11, the profile of the exterior contour of right guide part 721 and right guide ring 15 inwalls can be the stage bodies such as oval stage body, triangle stage body, cuboid or changeable stage body that left and right directions is provided with.
The above is merely preferred embodiments of the present invention; The present invention is not limited to above-mentioned embodiment; In implementation process, possibly there is local small structural modification; If various changes of the present invention or modification are not broken away from the spirit and scope of the present invention, and belong within claim of the present invention and the equivalent technologies scope, then the present invention also is intended to comprise these changes and modification.
