Abstract
In a magnet arrangement for the fastening of prostheses, in which a magnet which can be inserted into a prosthesis and a magnet to be implanted or to be fastened on an implant are provided, there is provided, to achieve a reliable mounting during a displacement movement of the prosthesis, a guide, by which the two magnets are guided on one another in such a manner that they are displaceable telescopically relative to one another in the holding direction of the prosthesis.
Claims5
A magnet system for fastening a prosthesis to a body, comprising a pair of magnetized sections connectible to the prosthesis and body, respectively;
- a first of said magnetized sections forming a recess having an inner portion and an outer portion;
- said inner portion comprising a floor of said recess and being magnetized with a first polarity;
- said outer portion being magnetized with a second polarity opposite said first polarity;
- a second of said magnetized sections including a projection disposed within said recess for inward and outward sliding movement therein;
- a free end of said projection being positioned opposite said floor and in contact therewith when said projection is fully inserted in said recess;
- said free end being magnetized with said second polarity so as to be normally magnetically attracted by said floor into contact therewith, and magnetically repelled by said outer portion of said recess in a direction toward said floor when said free end is moved out of contact with said floor.
