Description
This study explores the fabrication of barbed sutures of
biodegradable polymers, such as P4HB and Cagut, using
femtosecond laser. Barbed sutures are on high demand for
minimally invasive procedures, with the benefits of
reducing the need for knots, enhancing would closure
stability and minimizing tissue trauma. Traditional
approaches, such as mechanical cutting and longer-pulses
lasers, results in imprecise cutting and extended thermal
damage, whereas ultrashort pulse durations of femtosecond
lasers enable high precision cutting, with the added
benefits of minimal heat-affected zones. This research
investigates the effects of key laser parameters, such as
laser fluence, repetition rate, overlapping ration and
scanning passes, on barb quality and identifies the optimal
conditions for consistent, high-quality barbs with sharp
tips and minimal thermal damage. Moreover, the threshold
fluence values established here, for P4HB and Catgut, serve
as a reference for future study. Results demonstrate that
femtosecond laser technology can be a promising alternative
to traditional barb fabrication techniques.
