Potts scissors with a 45° angle are specialized surgical instruments used primarily for cutting and extending incisions in blood vessels (arteries and veins) during cardiovascular and thoracic procedures, such as those for bypassing blockages. Their angled tips allow surgeons to insert the blades into a vessel and make precise, straight cuts along its wall, enabling tasks like vessel opening and the removal of blockages.

Vascular Surgery:

Ideal for extending arteriotomies (incisions in arteries) and venotomies (incisions in veins).

Bypass Operations:

Used in procedures like coronary artery bypass and femoropopliteal bypass to create access points in vessels.

Removal of Blockages:

Crucial for operations like embolectomy and thrombectomy, where a surgeon needs to create an incision to remove a blood clot.
