Medical force measuring system
First Claim
1. Medical force measuring system for measuring a force that is effective between two prosthesis parts of a joint prosthesis, the two prosthesis parts being connected to one another in an articulated manner, the joint prosthesis comprising a ball joint or a partial component thereof, which force measuring system comprises:
- a measuring instrument, the measuring instrument comprising;
a sample joint element having a sample joint surface, the sample joint element being formed in correspondence with a first joint element that forms a part of the ball joint and comprises a joint surface that is formed in correspondence with the sample joint surface and is moveable into engagement therewith for forming a sample ball joint, andan indicating device arranged or formed on the measuring instrument which cooperates with the sample joint element for indicating a force that is effective on the sample joint surface or a partial component of the force that is effective on the sample joint surface,wherein;
the measuring instrument further comprises a coupling element;
the medical force measuring system further comprises a medical instrument which is couplable to the measuring instrument,the medical instrument further comprises an instrument coupling device,the instrument coupling device comprises a clamping element which is moveable into engagement in at least one of a force-locking and a positive-locking manner with a prosthesis part or the medical instrument on the one hand and with the coupling element on the other hand, andthe clamping element is in the form of a clamping ring which, in a clamping position, engages in at least one of (a) an annular groove in the prosthesis part or in the medical instrument on the one hand, and (b) an annular groove in the coupling element on the other hand.

Abstract
A medical force measuring system is provided for measuring a force effective between two prosthesis parts that are connected to one another in articulated manner in a joint prosthesis which includes a ball joint or a partial component thereof. The force measuring system includes a measuring instrument which has a sample joint element with a sample joint surface. The sample joint element is formed in correspondence with a first joint element that forms a part of the ball joint and has a joint surface which is formed in correspondence with the sample joint surface and is moveable into engagement therewith for forming a sample ball joint. The measuring instrument also includes at least one of a measuring device and an indicating device which cooperates with the sample joint element for measuring and/or indicating a force (or a partial component thereof) effective on the sample joint surface.
