Orthopedic insert measuring system for having a sterilized cavity

摘要

At least one embodiment is directed to an insert for measuring a parameter of the muscular-skeletal system. The insert can be temporary or permanent. In one embodiment, the insert is prosthetic component for a single compartment of the knee. The insert comprises a support structure and a support structure respectively having an articular surface and a load bearing surface. The height of the insert is less than 10 millimeters. At least one internal cavity is formed when support structures are coupled together for housing electronic circuitry, sensors, and the power source. The cavity is sterilized through a port. A membrane is between the port and the cavity. A sterilization gas permeates the membrane for sterilizing cavity. The membrane prevents ingress of solids and liquids to the cavity.

主权项

1. An insert measurement system for measuring a parameter of the muscular-skeletal system including:
a first support structure having an articular surface; a second support structure where the first and second support structure are coupled together and hermetically sealed a load-bearing plate where the insert has at least one interior sterilized cavity housing electronic circuitry operatively coupled to at least one sensor, where the load-bearing plate lies between the articular surface and the at least one sensor, where the load-bearing plate is configured to transmit a portion of a load on the articular surface to the at least one sensor where the insert is placed within sterilized packaging such that the external surfaces and the at least one interior sterilized cavity remain sterile until used.
