Potts Scissors with a 125° angle are specialized surgical instruments used primarily in cardiovascular and thoracic procedures for precise cutting of vessels and delicate tissues, especially in deep, confined, or hard-to-reach surgical areas. Their unique angled blades allow surgeons to create precise, straight incisions along vessel walls (arteriotomies) and perform dissections with increased access and control. 

Vascular Surgery:

To make precise cuts along blood vessels, particularly in complex cardiovascular operations.

Thoracic Procedures:

For accessing and working in the deep and confined spaces of the chest.

Vascular Graft Operations:

To dissect vessels and enlarge vascular incisions when preparing for grafts.
