METHOD OF ULTRASONIC INTRA-OPERATION DIAGNOSTICS OF BONE TISSUE STATE

摘要

FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, and is intended for ultrasonic intra-operation diagnostics of bone tissue state. Impact on bone tissue with ultrasonic signal of set frequency is performed with further estimation of change of said signal parameters. As information parameter used is input impedance of ultrasonic peisoelectric ceramic emitter, density of bone tissue being determined by change of active constituent, elasticity being determined by change of reactive constituent of impedance with respect to impedance of emitter at idling. Ultrasonic impact is performed at frequencies from 26 to 44 kHz. ^ EFFECT: provision of ultrasonic intra-operation diagnostics of bone tissue state. ^ 2 cl, 1 dwg
