Abstract
Official abstract text for this publication.
An endoprosthesis is proved which includes an elongate housing having a drive secured through a threaded drive shaft to an extension shaft therein, the drive operable to cause the extension shaft to move axially with respect to the body, and the extension shaft and housing configured to be securable to a bone to act as a prosthetic replacement for removed bone. An operating system for the endoprosthesis is also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. An endoprosthesis comprising an elongate housing having a drive secured through a threaded drive shaft to an extension shaft therein, the drive operable to cause the extension shaft to move axially with respect to the housing and the extension shaft and housing configured to be securable to a bone to act as a prosthetic replacement for removed bone, and for the drive to be operable through a control circuit which includes an inductive coil, wherein the control circuit is configured to provide a predetermined output which operates the drive in a step-wise fashion upon receiving power through the inductive coil and includes a number of cascaded circuits, each of which provides an output which drives one phase of the motor. 2. An endoprosthesis as claimed in claim 1 in which the control circuit is configured through hardwiring. 3. An endoprosthesis as claimed in claim 1 in which the drive includes a motor and gearbox. 4. An endoprosthesis as claimed in claim 3 in which the motor is a piezoelectric motor. 5. An endoprosthesis as claimed in claim 1 in which the cascaded circuits each include a time delay. 6. An endoprosthesis as claimed in claim 1 in which the drive, drive shaft and extension shaft are substantially co-axially arranged. 7. An endoprosthesis as claimed in claim 1 in which a strain gauge is secured to a part of the endoprosthesis to measure strain of that part. 8. An endoprosthesis as claimed in claim 7 in which the strain gauge transmits strain information through the skin using radio techniques or by using coded patterns of current impulses through the inductive coil.
