Suture-Tool: A Mechanical Needle Driver for Standardized Wound Closure.

Area of Science:

• Surgical Innovation
• Medical Device Development
• Wound Closure Techniques

Background:

• Laparotomy necessitates standardized abdominal access and closure to prevent complications like infections and hernias.
• Current suture techniques, aiming for a suture length-to-wound length (SL/WL) ratio of ≥4:1, can be time-consuming and technically challenging.
• Minimizing abdominal wall complications requires efficient and high-quality wound closure methods.

Purpose of the Study:

• To develop and evaluate a novel mechanical suture device for standardized and efficient fascial closure.
• To assess the device's ability to achieve a high SL/WL ratio compared to conventional methods.
• To determine the impact of the device on suture time during wound closure.

Main Methods:

• A mechanical suture device (Suture-tool) was engineered for standardized, rapid, and safe wound closure.
• Ten surgeons utilized the Suture-tool and conventional needle driver suturing (NDS) with the 4:1 technique on an animal tissue model.
• Outcome measures included SL/WL ratio, number of stitches, and total suture time.

Main Results:

• The Suture-tool achieved the target SL/WL ratio of ≥4 in 95% of closures, compared to 30% with NDS (p<0.001).
• Suture time was reduced by 30% using the Suture-tool (2 min 54 s vs. 4 min 5 s; p<0.001).
• The number of stitches required was comparable between the two methods.

Conclusions:

• The mechanical suture device demonstrates potential for rapid, standardized, high-quality fascial closure.
• This innovation may offer a solution to the challenges of achieving optimal suture length-to-wound length ratios.
• The device's efficiency could reduce operative time, benefiting both surgeons and patients.
