Orthopaedic safety system

摘要

An orthopaedic device for generating one or more strain signals representative of the strain in a bone in response to a force applied to the bone. The device includes an encircling member (11) for encircling the bone of a subject and a sensor member (13) connected thereto, the sensor member including a strain sensor (14). In a preferred embodiment the strain sensor comprises one or more bridging members configured to break when subjected to a particular strain.

主权项

1. A force indicator member for use with an orthopaedic implant system, wherein the force indicator member comprises a main body having a connection member to connect the main body to a driving member or to an implant of the orthopaedic implant system, and
wherein the main body of the force indicator is configured to receive a force applied to implant an orthopaedic implant into a bone of a subject, the force indicator comprising a frangible structure, the frangible structure configured to break above a pre-determined force applied to the main body and further wherein, the force indicator member generates a signal to a user upon breaking of the frangible structure, the signal indicative of a risk of fracture to the bone.
