3 results about "Extracorporeal shock wave" patented technology

This invention relates to the field of medical technology, specifically to a portable low-energy extracorporeal shock wave lithotripsy system; comprising: a portable main unit module, a low-energy shock wave module, a miniature ultrasound positioning module, an AI intelligent control module, and a respiratory compensation module. This invention constructs a dual-focal constructive interference acoustic field and energy optimization model of a piezoelectric ceramic array. Within a safe range where the single pulse energy density is reduced, it effectively pulverizes stones using the shear stress generated by the sound pressure gradient between the two focal points, thereby significantly reducing the system's hardware dependence on power reserves and high-power heat dissipation, achieving a transformation from a single-pulse system to a trolley-type portable structure. Simultaneously, the system overcomes the off-target problem caused by dynamic respiratory displacement by using ultrasound image coordinate matrix mapping and an electro-mechanical dual-mode collaborative compensation mechanism, with microsecond-level instantaneous deflection of the electronic focal domain of the phased array to offset the mechanical response lag of the servo motor through phased array microsecond-level electronic focal domain instantaneous deflection.

This invention relates to the field of extracorporeal shock wave technology and discloses a method for recommending personalized parameters for an extracorporeal shock wave therapy device based on medical data. The method includes: acquiring ultrasound images of a patient in a specific knee-flexed posture, extracting lesion and bone surface feature information, and calculating the effective incident angle and lesion depth; determining the waveguide matching angle and the main lobe angle width based on soft tissue sound velocity, bone Rayleigh phase velocity, and device characteristics, and establishing an angle distribution model to calculate the angular energy ratio. When the energy distribution is abnormal, the treatment head rotation angle and skin translation are automatically adjusted to keep the focus aligned with the lesion center; the energy flux density is adjusted based on tissue attenuation characteristics to obtain the nominal energy flux density; treatment points are arranged along the long axis of the patellar tendon, and shock waves are emitted only at locations where the angular energy ratio meets the threshold, thereby generating a personalized treatment parameter scheme to achieve precise focusing and individualized control of the treatment energy.

This invention discloses a synergistic therapeutic system and method for generating extracorporeal shock waves. The system includes an ultrasound transmitting device, an image guidance module, a synchronization module, and a control module. The image guidance module is used to image the cardiac structure in real time and determine the target point. The synchronization module controls a first transducer array to emit pacing pulses according to a preset pacing rhythm, determining and maintaining the heart at a stable pacing rhythm. Based on the real-time images fed back by the image guidance module within the pacing rhythm, it obtains the treatment window for each heartbeat cycle. The control module controls the image guidance module, receives the treatment window signal calculated by the synchronization module, and triggers a second transducer array to emit treatment pulses towards the target point within the treatment window to soften the target point. The frequency of the treatment pulses is an integer multiple of the pacing rhythm or is set synchronously. This achieves safe, efficient, and synergistic integrated ultrasound softening therapy for sclerotic valves.
