WG 7 - TC 87/WG 7

IEC 63045:2020 is applicable to
– therapy equipment using extracorporeally induced non-focused or weakly focused pressure pulses;
– therapy equipment producing extracorporeally induced non-focused or weakly focused mechanical energy,
where the pressure pulses are released as single events of duration up to 25 µs.
This document does not apply to
– therapy equipment using focusing pressure pulse sources such as extracorporeal lithotripsy equipment;
– therapy equipment using other acoustic waveforms like physiotherapy equipment, low intensity ultrasound equipment and HIFU/HITU equipment.
This document specifies
– measurable parameters which are used in the declaration of the acoustic output of extracorporeal equipment producing a non-focused or weakly focused pressure pulse field,
– methods of measurement and characterization of non-focused or weakly focused pressure pulse fields.
This document has been developed for equipment intended for use in pressure pulse therapy, for example therapy of orthopaedic pain like shoulder pain, tennis elbow pain, heel spur pain, muscular trigger point therapy, lower back pain, etc. It is not intended to be used for extracorporeal lithotripsy equipment (as described in IEC 61846), physiotherapy equipment using other waveforms (as described in IEC 61689) and HIFU/HITU equipment (see IEC 60601 2-62 and IEC TR 62649).

Applies to - lithotripsy equipment using extracorporeally induced pressure waves; - lithotripsy equipment producing focused mechanical energy. Specifies - measurable parameters which could be used in the declaration of the acoustic output of extracorporeal lithotripsy equipment, - methods of measurement and characterization of the pressure field generated by lithotripsy equipment.

This standard specifies: - the essential non-thermal output characteristics of ultrasonic surgical units; - methods of measurement ot these output characteristics; - those characteristics which should be declared by the manufacturers of such equipment. This standard is applicable to equipment which meets the requirements of a, b and c below: a) ultrasonic surgical systems operating in the frequency range 20 kHz to 60 kHz; and b) ultrasonic surgical systems, whose use is the fragmentation or cutting of human tissue, whether or not those effects are delivered in conjunction with tissue removal or coagulation; and c) ultrasonic surgical systems, in which an acoustic wave is conducted by means of a specifically designed wave guide to deliver energy to the surgical site.
