Invasive in vivo treatment device based on micro electric explosion

Abstract

The invention discloses an invasive in vivo treatment device based on micro electric explosion. The treatment device comprises a high voltage power source, a storage capacitor, a trigger switch, a trigger device, an electric explosion probe and a patch cord. The high voltage power source and the storage capacitor are electrically connected, and the high voltage power source is configured to provide high voltage output and supply power to the storage capacitor; the storage capacitor, the trigger switch and the patch cord are sequentially connected to form a series circuit, the trigger device iselectrically connected with the trigger switch, and the trigger device is used for generating a pulse signal and acting on the trigger switch to enable the trigger switch to be turned on and off; thepatch cord is used for connecting the storage capacitor and the electric explosion probe to transmit the current. The diameter of the electric explosion probe as an output component of the explosionenergy is not more than 1mm. The treatment device is based on the micro electric explosion technology, can accurately control the explosion output energy, the action position and the action directionand can generate a powerful controllable explosion effect in a designated part in vivo to achieve the treatment effects of crushing calculus, destroying tumors and dredging pipes.

Description

technical field [0001] The invention relates to the technical field of invasive internal treatment devices, in particular to an invasive internal treatment device based on miniature electric explosions. Background technique [0002] Explosion effects have been successfully applied in the field of medical treatment. For example, ESWL (extracorporeal shock wave lithotripsy) technology is to convert the energy released by electric spark explosion or explosive explosion into shock wave, transmit it into the human body and focus it, so as to crush human stones, and has become an important stone treatment technology. means. [0003] The current ESWL technology needs to be matched with precise focusing technology, that is, through specific technical means, the shock wave energy can be accurately focused on the location of the stone, thereby crushing it. The disadvantage of this technology is that the shock wave may cause uncontrollable damage to tissues or organs in other parts o...

AI Technical Summary

Problems solved by technology

The disadvantage of this technology is that the shock wave may cause uncontrollable damage to tissues or organs in other parts of the human body during the propagation process in the body, so there is a certain risk, especially when the stone is located in a deep position in the body, a relatively large Large explosion energy can offset the attenuation of the shock wave during the transmission of the human body, thereby achieving the purpose of crushing the stones and further increasing the risk of harm to the human body
