Adjustable wide voltage discharge tube

Abstract

The invention relates to an adjustable wide voltage discharge tube, belonging to the technical field of medical appliance. An encloser of the discharge tube is fastened with an insulation shell, a discharge plate is arranged between the encloser and the insulation shell, one end of the discharge plate is connected with a wiring block, two ends of the periphery of the encloser and the insulation shell are glued with trigger bar fixed plates; the trigger bar fixed plates, the encloser and the insulation shell are provided with connection holes, and the trigger bars are inserted into the connection holes; the invention is characterized in that screw thread is arranged inside of each connection hole, the end of each trigger bar is provided with corresponding screw thread, the connection hole and the trigger bar are directly connected by the screw thread, and the end of the trigger bar is connected with a subsidiary fixed block. By screw thread rotation, distance regulation between the heads of the trigger bars can realize the voltage regulation and satisfy the working requirement of the discharge tube in high voltage pulse circuit required by an interchangeable extracorporeal shock wave stone breaker.

Description

technical field [0001] The invention relates to a wide-voltage discharge device, in particular to an adjustable wide-voltage discharge tube, which belongs to the technical field of medical equipment. Background technique [0002] During the use of extracorporeal shock wave lithotripters on the market, the energy and working voltage range required by the hydraulic wave source and the electromagnetic wave source are different. The working voltage required by the hydraulic type is lower, while the electromagnetic type is higher. For example, the interchangeable extracorporeal shock wave lithotripter, the working voltage range required by the hydraulic type is selected at 4.0-6.0KV; the required operating voltage range of the electromagnetic type is selected at 8.0-11.0KV. [0003] Specifically, the discharge performance of the discharge tube in the high-voltage pulse circuit is a prerequisite for determining the normal use of the rock crusher. In order to meet the normal discha...

Problems solved by technology

[0004] However, the distance between the trigger rods in the discharge tube of the traditional high-voltage pulse circuit is fixed, and the entire discharge tube needs to be replaced when a different specification is selected, which is neither safe nor convenient.

At the same time, the existing fixed type has a short service time, and the gap becomes larger due to high-voltage discharge burning, which affects its discharge performance

Moreover, frequent replacement and lack of debugging will make it prone to errors. The two specifications, the exchange of hydraulic and electromagnetic wave sources will increase the error rate

Furthermore, in order to adapt to different usage specifications, repeated manufacturing is required, and the production process is various, which is not conducive to popularization
