IMPLANT Russian patent published in 2004 - IPC

FIELD: medical engineering.

SUBSTANCE: device has longitudinal axle, distal end and proximal end with fitting recess propagating inward into the implant body for rigidly fixing connection journal of medical element therein. The implant makes connection to internal fitting recess side surface by means of geometrical or mechanical force locking in animal or human bone tissue. The medical element is adjacent to the fitting recess in state fixed by contact surface of the head part radially protruding outward with its cross-section outside of the fitting recess cross-section on its radial end on proximal implant end with its whole surface to matching contact surface of the implant on its proximal end. The fitting recess has cylindrical area beginning from proximal implant end and area with narrowing cross-section adjacent to it. Fitting recess cross-section has shape of rounded rectangle near the proximal implant end, and rounded square shape near it. Shape-to-shape transformation takes place with no jumps.

EFFECT: enhanced effectiveness of treatment; high reliability of protection against; uniform force transfer between medical element and implant.
