Orthopaedic monitoring system, methods and apparatus

A method for assessing the orthopaedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopaedic performance of the joint after the procedure.

Techniques for patient-specific milling path generation

Systems, methods, software and techniques for generating a milling path for a tool of a surgical system are provided. The milling path is designed to remove a resection volume associated with an anatomical volume. A reference guide is defined with respect to the resection volume. Sections are defined along the reference guide in succession. Each section intersects the reference guide at a different intersection point and is at a specified orientation relative to the reference guide at the intersection point. Each section further intersects the resection volume. A section path is generated to be bounded within each section and defined relative to the resection volume. A plurality of transition segments are generated and each transition segment connects section paths of successive sections along the reference guide.

SYSTEMS AND METHODS FOR IDENTIFYING AND LOCATING REFLECTORS USING ORTHOGONAL SEQUENCES OF REFLECTOR SWITCHING
20220400976 · 2022-12-22 ·

Systems and methods are provided for identifying and locating a plurality of reflector markers implanted within a target tissue region within a patient's body. A probe is provided that is activated to transmit electromagnetic signals into the patient's body, receive reflected signals from the patient's body, and in synchronization with transmitting the electromagnetic signals, deliver light pulses into the patient's body. The markers reflector tags modulate reflected signals from the respective markers based on orthogonal code sequences opening and closing respective switches of the markers to modulate the reflective properties of the markers. The probe processes the return signals to separate the reflected signals based at least in part on the code sequences to identify and locate each of the plurality of reflector tags substantially simultaneously.

Wireless position determination

The present invention relates to a system SY for determining a position of an RF transponder circuit RTC respective an ultrasound emitter unit UEU. The RF transponder circuit RTC emits RF signals that are modulated based on received ultrasound signals that are emitted or reflected by the ultrasound emitter unit UEU. The position of the RF transponder circuit RTC respective the ultrasound emitter unit UEU is determined based on a time difference ΔT1 between the emission of an ultrasound signal by the ultrasound emitter unit UEU and the detection by the RF detector unit RFD of a corresponding modulation in the RF signal emitted or reflected by the RF transponder circuit (RTC).
