Disposable provisional instrument component for evaluating the fit of an orthopaedic implant
First Claim
Patent Images
1. A method of using a disposable, single use provisional surgical instrument component for evaluating a fit of a corresponding orthopaedic implant wherein the method comprises:
- a) providing the provisional component with performance characteristics which are not suitable or strong enough for implant use in a static or dynamic loaded environment, but which are suitable for provisional use for evaluating the fit of the corresponding implant;
b) manufacturing the provisional component at least in part from a material which upon exposure to a heated environment will provide a visible indicator to discourage or prevent reuse of the provisional component;
c) sterilizing the component by gamma irradiation;
d) utilizing the component in a single surgical procedure to evaluate the fit of the corresponding implant;
e) disposing of the component after the single surgical procedure, whereby exposing the component to the heated environment in order to resterilize the component for reuse will cause the visible indicator to become visible to discourage or prevent reuse of the component.

Abstract
A provisional instrument component 1 for evaluating the fit of a corresponding orthopaedic implant. The component 1 is intended and designed to be a disposable, single use provisional instrument component. The provisional instrument component 1 is made of a material which can be sterilized by gamma irradiation, but which provides a visible indicator, such as visible deformation 10, upon resterilization by exposure to a heated environment, thereby discouraging or preventing re-use of the component 1.

7. A method of using a disposable, single use provisional surgical instrument component for evaluating a fit of a corresponding orthopaedic implant wherein the method comprises:
-
a) manufacturing the component at least in part from a material which upon exposure to a heated environment will provide a visible indicator to discourage or prevent reuse of the component; b) sterilizing the component by gamma irradiation; c) utilizing the component in a single surgical procedure to evaluate the fit of the corresponding implant; d) disposing of the component after the single surgical procedure, whereby exposing the component to the heated environment in order to resterilize the component for reuse will cause the visible indicator to become visible to discourage or prevent reuse of the component, and wherein the step of manufacturing the component further includes the step of including a mineral in the material which will release gas and cause visible deformation in a form of bumps or bubbles on the component upon exposure to the heated environment.
