System and method for assisting a surgeon to perform shoulder arthroplasty

Abstract

The invention concerns a system for assisting a surgeon for performing shoulder arthroplasty in a surgical field comprising a glenoid cavity of a patient's shoulder, the system comprising: - at least one extension pole intended to be attached to an instrument, the extension pole being configured to be non-magnetic-field-disturbing by material and / or by design; - an EM localization system comprising - an EM transmitter; - an EM instrument receiver attached to the extension pole, the extension pole permitting to keep the EM instrument receiver away from the instrument to which it is attached; - an EM bone receiver intended to be located near the glenoid cavity, preferably rigidly attached to a scapula of the patient's shoulder; - a retractor assembly adapted for retracting tissues around the glenoid cavity, the retractor assembly comprising at least one retractor configured to be non-magnetic- field-disturbing by material and / or by design, the EM transmitter being attached to said retractor configured to be non-magnetic-field-disturbing by material and / or by design, the EM transmitter, the EM instrument receiver and the EM bone receiver being configured for operating together by being arranged relative to each other within a functional area preliminary defined by a range of the EM transmitter, the extension pole being configured not to interfere with a-magnetic-field in the functional area.
