Abstract:
Background/NeedPrecision suturing in confined surgical fields poses ergonomic and visibility challenges, particularly in minimally invasive and reconstructive procedures. A novel Vertical Needle Holder (VNH) was designed to enhance control, angle precision, and accessibility in restricted spaces.Methodology and Device DescriptionThis proof-of-concept study evaluated the VNH's ergonomic design and suturing performance compared with a standard Mayo-Hegar needle holder. Thirty surgeons and surgical trainees participated in simulated suturing tasks using both instruments. Surgeon-reported outcomes were assessed using standardized synthetic-tissue suturing tasks and a structured Likert-scale questionnaire focusing on perceived precision, ergonomics, and ease of use.Preliminary ResultsSurgeons reported improved perceived precision and maneuverability of the VNH in confined spaces compared with conventional needle holders. Participants reported reduced wrist strain and greater visibility. The majority of participants (87%) rated the VNH as ergonomically superior to conventional needle holder designs.Current StatusThese findings suggest that the VNH offers an innovative, practical enhancement to traditional surgical tools, potentially improving safety and efficiency in complex operative fields. Further clinical validation is underway to confirm translational applicability.
