Adhesive films have come a long way in recent years. New materials and manufacturing process developments allow these thin polymer sheets to provide robust and reliable adhesion in various applications, including securing access incisions in minimally invasive spine closure. Here are three key ways advances in adhesive films are enabling secure closure in MIS spine procedures.
1. Improved Adhesion Strength
Traditionally, medical tapes and films used pressure-sensitive acrylate adhesives, which were adequate but not optimal. Today’s adhesive films have evolved, incorporating stronger adhesives like silicone or hydrocolloid. These materials provide immediate and robust adherence to the skin, maintaining their grip even under stress from movement or moisture during the healing process. Studies have demonstrated that silicone-based films can offer up to 40% greater shear adhesive strength compared to older acrylate tapes, ensuring that incisions remain securely closed.
2. Thinner and more flexible films
MIS spine techniques require passing instruments through small portals. This demands an exceptionally thin, pliable adhesive film to avoid complicating or hindering the procedure. Recently introduced adhesive films are as thin as 15 microns—similar to a sheet of copy paper! Their high flexibility and conformability allow for precise application to the skin for optimal closure.
3. Antimicrobial Properties
Any external adhesive could increase the infection risk. So, modern adhesive films incorporate antimicrobial features. Some films contain chlorhexidine, gluconate, or silver oxide to inhibit microbial growth at the incision site. Others utilize a polyurethane backing impregnated with antimicrobial ions. Reducing the bacterial load ultimately supports better healing and closure integrity. Reach out to Sharp Fluidics today and experience the future of surgical precision.
