<p>#CMT# #/CMT# 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). #CMT#USE : #/CMT# Instrument for operative removal of a defective heart valve. #CMT#ADVANTAGE : #/CMT# The cutting ring halves are manufactured from a flexibly ductile flat material volume, and the cutting ring halves are connected to each other by a single-axle articulation link to a circular cutting ring, and hence ensures the production of an accurate circular section when repairing the defective heart valve. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of constructional functional parts of an instrument. 10 : Guide pillar 11,12 : Mold halves 13,14 : Cutting ring 31 : Layer 32,33 : Contact protection.</p> |
