Mechanical dilator for coronary and peripheral vascular surgery

Area of Science:

• Vascular Surgery
• Surgical Instrumentation

Background:

• Coronary artery bypass and peripheral vascular surgeries require precise vessel manipulation.
• Current techniques for vessel incision and exposure can be challenging, risking collateral damage.

Purpose of the Study:

• To introduce a new vascular dilator designed for aortocoronary and peripheral vascular surgery.
• To demonstrate the instrument's utility in improving vessel incision and exposure during complex vascular procedures.

Main Methods:

• Description of a novel vascular dilator instrument.
• Application of the dilator during sequential anastomosis in coronary artery bypass.
• Utilization of the dilator in peripheral vascular surgery for patch angioplasty and anastomosis.

Main Results:

• The dilator enables precise vessel incision without damaging the opposite wall.
• It effectively maintains incision edges apart, eliminating the need for forceps or traction sutures.
• Facilitates expansion of arterial incision edges in peripheral vascular procedures.

Conclusions:

• The described vascular dilator represents a significant advancement in surgical tools for vascular interventions.
• It offers improved safety and efficiency in both coronary and peripheral vascular surgeries.
• The instrument aids in achieving better surgical outcomes by minimizing tissue trauma.
