Abstract

The invention relates to a shock wave generating device for a cardiovascular stenosis lesion. The shock wave generating device comprises a balloon catheter and an energy supply unit; the balloon catheter comprises an electrode pair arranged in a balloon and electrically connected with the energy supply unit; the energy supply unit is provided with a release state detection circuit for detecting an energy release state between electrodes of the electrode pair; the release state detection circuit comprises at least one of a pulse voltage detection circuit for detecting voltage between the electrodes of the electrode pair at the moment of discharging, and a resistance detection circuit for detecting the resistance between the electrodes of the electrode pair, and the electrode pair is connected with a pulse power supply. the electrode pair is connected to a pulse power supply, and a switch is arranged to control the duration of providing a pulse circuit for the electrode pair; the pulse voltage detection circuit and the resistance detection circuit are additionally arranged on the electrode pair and the switch to detect abrupt changes of the voltage and resistance between the electrode pair after energy release, and turning on and off of the switch is controlled, thus saving unnecessary energy waste.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a shock wave generating device for cardiovascular stenosis. Background technique [0002] Cardiovascular stenosis refers to human arteriovenous vessels, including coronary, peripheral, and intracranial vessels, due to abnormal lipid metabolism, lipids in the blood are deposited on the smooth intima of blood vessels, and gradually accumulate into atherosclerotic lipids. Plaque-like plaques, as time goes by, these plaques increase or even calcify, causing narrowing of the blood vessel lumen, blocking blood flow, leading to ischemia of downstream blood vessels and the body, and corresponding clinical manifestations. If the stenosis occurs in the coronary artery, it will cause palpitations, chest pain, dyspnea, and angina pectoris. In severe cases, it will lead to myocardial insufficiency or myocardial necrosis; if it occurs in the periphery, it will cause skin temperature ...
