Embodiment 1

[0051] In the optional scheme of this embodiment, such as Figure 5 As shown, preferably, the pulse discharge adopts three consecutive discharge pulses. The specific operation form is: the compound enhanced pulse discharge control unit 3 controls the high voltage switch control module 5 to output 3 consecutive discharge pulses, the discharge interval is 300 milliseconds, the discharge time is 0.5 microseconds, and the discharge voltage is 2000 volts. Due to the long interval between the three-strike discharge pulses and the continuous discharge times are only three times, it is suitable for shocking soft stones.

Embodiment 2

[0053] In the optional scheme of this embodiment, such as Image 6 As shown, preferably, the pulse discharge adopts ten consecutive discharge pulses. The specific operation form is: the compound enhanced pulse discharge control unit 3 controls the high voltage switch control module 5 to output 10 consecutive discharge pulses, the discharge interval is 14 milliseconds, the discharge time is 0.5 microseconds, and the discharge voltage is 2000 volts. Since the number of discharges of the ten-strike discharge pulse is more, the number of continuous discharges is ten times, which is suitable for shocking soft stones.

Embodiment 3

[0055] In the optional scheme of this embodiment, such as Figure 7 As shown, preferably, the pulsed discharge employs rapid cycle discharge pulses. The specific operation form is: the compound enhanced pulse discharge control unit 3 controls the high-voltage switch control module 5 to output a group of 5 continuous discharge pulses at intervals of 1 second, the discharge interval is 18 milliseconds, the discharge time is 0.5 microseconds, and the discharge voltage is 2000 volts . Because the rapid cycle discharge pulses output pulse discharges in groups, the number of discharge pulses is more and the interval time is shorter, which is suitable for shocking hard stones.

Abstract

The invention provides an in-vivo electrohydraulic lithotripter circuit and a pulse discharge lithotripsy method, and relates to the technical field of medicinal electronic equipment. The in-vivo electrohydraulic lithotripter circuit comprises a control module and a charge module, wherein the control module comprises a hybrid reinforced pulse discharge control unit; the control module is used for controlling the charge module to charge and discharge power through the hybrid reinforced pulse discharge control unit. The in-vivo electrohydraulic lithotripter circuit provided by the invention adopts the control circuit for positioning, stone can be relatively precisely positioned, proper pulse electric shock can be output from the control module of the in-vivo electrohydraulic lithotripter circuit according to sizes and properties of the stone, and non-disease parts of patients are relatively slightly damaged. On the basis, the invention further provides the pulse discharge lithotripsy method.

Description

technical field [0001] The invention relates to the technical field of medical electronic equipment, in particular to an internal lithotripsy circuit and a pulse discharge lithotripsy method. Background technique [0002] Stones in the body are frequently-occurring and common diseases. The human liver and gallbladder system, urinary system and digestive system are all organs and parts that are prone to stone formation. The etiology of calculi is complex and harmful, which brings great pain and influence to patients. If it is not treated in time, it will seriously threaten people's health and life. [0003] The traditional surgical treatment of stones is traumatic, and postoperative complications are unavoidable, which brings long-term discomfort to patients and has the potential risk of inducing other serious diseases, which cannot meet the needs of patients' rehabilitation. Therefore, a safe and effective lithotripsy method is the medical goal pursued by medical workers a...
