SENSING MULTI AXIAL SCREW HEAD

Abstract

Load-sensing implants, sensor packages, and surgical-site monitoring systems are disclosed. A load-sensing implant includes an attachment portion configured to secure the implant to a bone of a subject. The implant further includes a receiver portion configured to receive and secure a longitudinal member and an electronics enclosure disposed adjacent the receiver portion and forming a common wall with the receiver portion. The electronics enclosure includes a sensor package comprising multiple strain sensors disposed on a backing, the sensor package configured to sense, via the common wall, forces applied to the receiver portion by the longitudinal member and support electronics. The support electronics are configured to receive, from the sensor package, data representing the sensed forces, and transmit the received data to an external device.
