Instrument for removing a defective heart valve during an operation

摘要

The instrument has two mold halves (11,12) arranged at or on a coaxial guide pillar (10) in a distance from each other. The mold halves are adjusted with each other axially by a relative guide pillar. Every section of the mold halves is formed from two semicircular cutting ring halves. Every cutting ring halves are manufactured from a flexibly ductile flat material volume. The cutting ring halves are connected to each other by a single-axle articulation link to a circular cutting ring (13,14).
