Articulating and Reloadable Fixation Devices for Hernia Repair

Area of Science:

• Surgical Technology
• Minimally Invasive Surgery
• Biomaterials Engineering

Background:

• Laparoscopic ventral hernia repair frequently utilizes tacks and fasteners for mesh fixation.
• Current tack deployment systems often struggle to achieve optimal perpendicular placement, potentially causing mesh migration, recurrence, and requiring additional surgical ports.
• Existing systems are typically single-use, increasing costs and waste associated with mesh fixation.

Purpose of the Study:

• To introduce novel tack deployment systems designed to overcome the limitations of current devices used in laparoscopic ventral hernia repair.
• To present innovative instruments that facilitate perpendicular tack deployment and offer reloadable fixation options.
• To address challenges in achieving optimal mesh fixation, reduce surgical complications, and decrease healthcare costs.

Main Methods:

• Development of tack deployment instruments featuring an articulating shaft or hinge mechanism.
• Incorporation of reloadable fixation capabilities into the deployment devices.
• Evaluation of the devices' ability to achieve perpendicular tack placement and improve access within the abdominal cavity.

Main Results:

• The new deployment instruments allow for improved access to various abdominal cavity regions.
• Perpendicular tack placement is more consistently achieved, potentially reducing tack failure and mesh migration.
• Reloadable fixation options decrease overall costs and minimize surgical waste.

Conclusions:

• Novel tack deployment systems offer significant advantages for laparoscopic ventral hernia repair.
• Articulating or hinged instruments enhance maneuverability and enable optimal tack placement.
• Reloadable devices provide a cost-effective and environmentally conscious alternative to current fixation methods.
