The present invention relates to a system for the controlled fragmentation of solids by means of acoustic beams, comprising at least one acoustic beam generation unit (); and one feedback and control unit () of said generation unit (). Advantageously, the acoustic beams generated by the system are acoustic vortex beams; and the feedback and control unit () further comprises a feedback subsystem (), configured to receive the information relating to the fragmented solids and to utilize it so as to adapt the operation of the acoustic beam generation unit (). Given that the generation of shearing stresses is more efficient using vortex beams, the amplitudes of the ultrasonic field needed to fragment the calculi are much lower than in current extracorporeal shock wave lithotripsy techniques. Likewise, the system minimizes unwanted effects on soft tissues surrounding the solid.
