Definitions
- FIG. 8a is a schematic diagram of the electrode components according to the second and third embodiments of the present invention.
- the first switch 551 of the trigger unit 550 When the high-voltage generator 521 charges the high-voltage capacitor 523, the first switch 551 of the trigger unit 550 is in a closed state, and the second switch 552 is in an open state; when the electrode balloon catheter reaches the treatment position, the logic process
- the unit 510 controls the trigger unit 550 to change the states of the first switch 551 and the second switch 552, so that the first switch 551 is turned off and the second switch 552 is turned on.
- the positive electrode 321 and the negative electrode 322 apply a voltage to form a relatively large current, so that an arc is generated between the positive electrode 321 and the negative electrode 322 immersed in the filling solution 110 , and the arc generates a shock wave in the filling solution 110 .
- the conduit connector 340 includes an outer positive wire 341 and an outer negative wire 342 , the outer positive wire 341 is connected to the positive wire 311 , and the outer negative wire 342 is connected to the negative wire 312 .
- the operation handle 580 is used to control the opening and closing of the logic processing unit 510 .
- S7 Determine whether there is a short circuit.
- the high-voltage generation processing device 500 detects whether the circuit is short-circuited. If a short circuit is detected, the discharge is terminated immediately, and if no short circuit is detected, the next step is entered.
- the first embodiment further provides an electrode member 320 , and the electrode member 320 of the first embodiment will be described in detail below with reference to FIG. 1 , FIG. 7 a and FIG. 7 b .
- the electrode member 320 is used for an electrode balloon catheter. It should be understood that the electrode member 320 can be applied to the electrode balloon catheter as described above, and can also be used for other electrode balloon catheters, for example, inflexible positive and negative electrode catheters are used. Electrode balloon catheter for electrode wire.
- the electrode member 320 includes: a first electrode 3201 , a second electrode 3202 and a receiving structure 3203 .
- the accommodating structure 3203 can be, for example, a circular structure, the accommodating structure 3203 is disposed on the first electrode 3201, preferably penetrates through the accommodating structure 3203 disposed on the first electrode 3201 , in other embodiments, the receiving structure 3203 may also be disposed on the surface of the first electrode 3201 .
- the accommodating structure 3203 may be disposed at the side end of the first electrode 3201 , or may be disposed at the middle position of the first electrode 3201 .
- the accommodating structure 3203 can also be in the shape of a rectangle, a square, a rhombus or a triangle.
- the shape, size and position of the accommodating structure 3203 can be determined according to the position, direction and size of the required shock wave, and those skilled in the art can Set according to actual requirements, and the shape of the receiving structure 3203 is not limited in this embodiment.
- the first electrode 3201 and the second electrode 3202 are arranged spaced apart to ensure that the space between the two can be used for filling with filling fluid, so that the first electrode 3201 and the second electrode 3202 are a single-layer electrode structure separated in parallel , reducing the passing size of the electrode balloon catheter.
