Three, summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, design a kind of easy to use, and the radio frequency bundling electrode that can control arbitrarily of its electrode deployed condition.

Basic ideas of the present utility model are, make traditional push-pull structure into structure by the displacement of rotating band moving electrode, thereby also can pass through sensor senses electrode displacement situation further, and by relevant device show electrode deployed condition or control electrode deployed condition.

This utility model specifically is achieved in that

A kind of radio frequency bundling electrode, comprise needle tubing, insert the electrode in the needle tubing, the holder of needle tubing is connected in the electrode power-line on the electrode, it is characterized in that the electrode afterbody is fixed on the feather key, feather key and one part of turning is threaded, the part afterbody of turning is fixedlyed connected with a driving shaft, and feather key and the part of turning all place in the sleeve pipe, wherein:

Be provided with the concavo-convex chute or the sliding closure that cooperatively interact between feather key outer wall and the internal surface of sleeve pipe vertically;

Turn and radially be provided with the concavo-convex stopper slot that cooperatively interacts or spacing protruding between part and the sleeve pipe;

Fixedly connected between the holder of needle tubing and the sleeve pipe.

In this utility model:

Described driving shaft can be by handle drives, also can be by a motor-driven.

Described chute can be opened on any one parts in feather key or sleeve pipe, and corresponding sliding closure then is located on another parts.

Described stopper slot can be opened on any one parts in turn part or sleeve pipe, corresponding spacing protruding then being located on another parts.

Described feather key can be tapped hollow, and the part of turning of Pei Heing then is to be with externally threaded screw rod with it; Certainly, feather key also can be to be with externally threaded screw rod, and the part of turning of Pei Heing then is tapped hollow with it.But when feather key is screw rod, be located at the setting that interlaces of sliding closure on the feather key and thread segment, promptly one section is provided with sliding closure, has attacked external screw thread on another section.Further scheme is: driving shaft is seated in the shell, and driving gear is housed on driving shaft, and the driven gear that cooperates with driving gear also is housed in shell, and the axle of driven gear links to each other with a pick off that is fixed in the housing.

Also standard interface can be housed on shell, electrode power-line and sensor power supply line all are connected on the standard interface.

Further scheme is: described holder is made of by being threaded chuck and binding nut.

Further scheme is again: the electrode afterbody is fixed on the feather key by pinching screw.

Further scheme is again: also have aperture on the telescopic wall vertically, electrode power-line places this aperture.

The utility model has the advantages that, the deployed condition of electrode can arbitrarily increase according to the size of focus or dwindle, thereby and can control motor rotation by pick off and control deployed condition in real time, also can send into Computer Processing to deployed condition and show by pick off with 3-D view or numeral.

Five, implementation

Below, in conjunction with the accompanying drawings this utility model is done detailed description.

As Fig. 1 and Fig. 2, the operation principle of this radio frequency bundling electrode is: handle 1 passes through driving shaft 17 and links to each other with screw rod 13, because of increasing spacing protrudingly and cooperates on the screw rod 13, screw rod 13 can only and can not be seesawed with driving shaft 17 rotations with stopper slot on the sleeve pipe 15.Screw rod 13 cooperates with female thread feather key 5, and the convex sliding closure is arranged on the feather key 5, and is to have the spill sliding tray in the sleeve pipe 15 therewith accordingly, and feather key 5 just can not rotate with screw rod 13 like this, and slide in front and back under the effect of screw thread on the contrary.Multiple warhead electrode 7 links to each other with feather key 5 by pinching screw 12.Needle tubing 6 pass chuck 11 back by binding nut 14 with its clamping.Electrode power-line 4 is connected to the electrode afterbody, and is connected to after passing in the aperture from sleeve pipe 15 on the standard interface on the housing 16.Synchronous operated driving gear 3 is housed on driving shaft 17, the driven gear 8 that cooperates with driving gear is housed on housing 16, the axle of driven gear 8 links to each other with the pick off 10 on being fixed in housing 17, and pick off 10 power lines 9 are connected on the standard interface 2.

When rotary handle to the right, gear coupling drives pick off, passes to Computer Processing by the pick off connecting line.Screw rod is along with handle rotates simultaneously, because screw rod and feather key employing special structural design, thus feather key under the effect of screw rod, in trocar sheath 15 along the translation forward of needle tubing 6 directions, and with feather key 5 link to each other by pinching screw 12 because of electrode 7 this moment, so electrode 7 travels forward.When it went out stainless steel outer sleeve pipe 6, multiple warhead electrode 7 just launched, and returns to its preset condition.Its state size can be controlled by its proal distance, and proal distance is bigger, and the electrode 7 of going out the stainless steel outer sleeve tube is longer, and unfolded state is bigger.And the deployed condition of this moment is finished by sensing system.Bundling electrode 7 deployed conditions are directly proportional with its distance that seesaws, and the distance that seesaws is directly proportional with the screw rod rotating cycle.The rotating cycle of screw rod is converted into correspondingly the signal of telecommunication by two gear coupling to pick off and sends into Computer Processing and show with three-dimensional image or numeral.

When rotary handle 1 left, just indentation of electrode 7.Pass through rotary handle to the left or to the right like this, the electrode that just can obtain wanting launches size.

As Fig. 3, Fig. 4, Fig. 5 and Fig. 6, sleeve pipe 15 right-hand members have annular spacing groove, and sleeve pipe 15 inwalls have one group of sliding tray symmetrically, also have flute profile wiring aperture simultaneously.

As Fig. 7 and Fig. 8, be provided with sliding closure on feather key 5 both sides.

As Fig. 9, the part of turning (screw rod) 13 is provided with spacing protruding.

As Figure 10, Figure 11 and Figure 12, chuck 11 left end heads have "+" font groove, will screwing and tightly needle tubing 6 is waled with screw thread after binding nut 14 is loaded onto.
