Kärldilaterare

Kärldilaterare, also known as a cardiac dilator, is a medical instrument used in open-heart surgery. Its primary function is to gently retract and hold open the heart chambers, particularly the atria and ventricles, during surgical procedures. This provides the surgeon with a clear and unobstructed view of the surgical field, allowing for precise manipulation and repair of delicate cardiac tissues.

The design of a kärldilaterare typically involves a series of blades or spatulas that are inserted into the heart chamber. These blades are often adjustable, allowing the surgeon to control the degree of dilation and tailor it to the specific needs of the patient and the surgical approach. The materials used in their construction are usually biocompatible and sterilizable, ensuring patient safety.

Kärldilaterare are essential tools for various cardiac surgeries, including valve repair or replacement, septal defect closure, and procedures involving congenital heart abnormalities. By maintaining adequate exposure of the heart chambers, these instruments contribute significantly to the success and safety of complex cardiac operations. The use of a kärldilaterare is a critical step in managing the anatomical landscape during these intricate surgical interventions.
