Collapsible Detection Antenna for Surgical Articles

Abstract:

A collapsible detection antenna (10) to detect electromagnetic tags (12) of surgical articles (14) in an operating room (16) includes an antenna assembly (18) configured to detect the electromagnetic tags (12). The antenna assembly (18) is configured to move between a deployed configuration and a collapsed configuration. In the deployed configuration, the antenna assembly forms an antenna loop (20) configured to detect the electromagnetic tags (12). The antenna assembly (18) has a greater detection range in the deployed configuration than in the collapsed configuration. The deployed configuration corresponds to a tuned shape of the antenna assembly (18) sufficient to detect the electromagnetic tags (12) in the deployed configuration.
