A triangular cutting arteriotomy scissors facilitating end-to-side anastomoses.

Area of Science:

• Microsurgery
• Vascular Surgery
• Surgical Instrumentation

Background:

• End-to-side anastomoses are preferred for preserving distal blood flow and reducing vascular occlusions.
• Significant vessel size discrepancies are a key indication for end-to-side techniques.
• Performing a precise arteriotomy is a critical and challenging step in end-to-side anastomosis.

Purpose of the Study:

• To introduce a new microsurgical instrument designed to facilitate arteriotomy.
• To improve the efficiency and precision of creating end-to-side vascular anastomoses.

Main Methods:

• Development of a novel microsurgical triangular cutting scissors.
• The instrument enables removal of oval tissue sections with a single cut.
• Comparison of the new instrument's performance against conventional methods using straight microscissors.

Main Results:

• The new scissors facilitate precise arteriotomy for end-to-side anastomoses.
• The instrument removes oval tissue pieces in a single action, unlike conventional double cuts.
• Potential advantages include improved efficiency and reduced complications in vascular reconstruction.

Conclusions:

• The developed microsurgical scissors offer a significant advancement in performing end-to-side vascular anastomoses.
• This innovation aims to simplify the challenging arteriotomy step, enhancing surgical practice.
• The instrument holds promise for improving outcomes in vascular reconstructive surgery.
