DEVICE FOR MEASURING FORCE VECTORS BETWEEN THE FEMUR AND THE TIBIA IN THE FLEXING AND/OR EXTENSION GAP IN ORDER TO ASSIST THE SURGEON IN KNEE PROSTHETICS

摘要

The invention relates to a device for measuring force vectors between the femur and the tibia in the flexing and/or extension gap in order to assist the surgeon in knee prosthetics. Said device comprises a sensor spacer (100) consisting of a cylindrical handle (20) with a carrier (30) for at least three sensors or three strain indicators and which is arranged on one end (20a) and is fixed to the handle (20) whereby said sensors or strain indicators are used as dynamometers for the conversion of the determined force distribution from the angle position between the femur and the tibia into signals which can be electrically evaluated. The carrier (30) anatomically forming the above-mentioned bone surface of the lower leg is flat and spoon-shaped and is preferably made of special steel and can be sterilised.
