BONE CEMENT REMOVAL USING REAL-TIME ACOUSTIC FEEDBACK

摘要

Systems and methods for bone cement removal using real-time acoustic feedback, such as during a drilling process in a revision arthroplasty, are discussed. A system for bone cement removal may include a processor to perform operation comprising receiving digital frequency data from the microphone, comparing at least a portion of the digital frequency data to a plurality of frequency signatures, and determining, based at least in part on the comparing, whether the portion of the digital frequency data is representative of a cut bone frequency or a cut bone cement frequency.

主权项

1. A system for bone cement removal, the system comprising:
a controller coupled to a cutting tool; a microphone; a processor coupled to a memory device, the memory device containing instructions that, when executed by the processor, cause the system to perform operations comprising:
receiving digital frequency data from the microphone;comparing at least a portion of the digital frequency data to a plurality of frequency signatures;determining, based at least in part on the comparing, whether the portion of the digital frequency data is representative of a cut bone frequency or a cut bone cement frequency; andin response to determining that the portion of the digital frequency data is representative of the cut bone frequency, sending an indication to the controller to adjust a control parameter of the cutting tool.
