Summary
Surgeons tested two suture grips for accuracy. Grip 2 demonstrated superior precision, while grip 1 with wavering achieved similar accuracy but increased tissue injury risk.
Area of Science:
- Surgical Techniques
- Biomechanics
Background:
- Surgical instrument grips are crucial for precision.
- Understanding grip mechanics can optimize suturing accuracy and patient outcomes.
Purpose of the Study:
- To compare the accuracy of two distinct surgical suture grips.
- To evaluate the impact of hand movement (wavering) on suturing precision.
Main Methods:
- Sixteen surgeons evaluated two suture grips (grip 1 and grip 2).
- Accuracy was measured by deviation from a target point during suturing, with and without hand wavering.
- Grip 1 involved fingers in rings and around the holder; grip 2 used all fingers around the holder.
Main Results:
- Grip 2 showed significantly higher accuracy (1.4 ± 1.1 mm) than grip 1 (2 ± 1.5 mm) without wavering (p < 0.01).
- Wavering reduced deviation in both grips, with grip 1 achieving comparable accuracy to grip 2.
- Increased wavering with grip 1 posed a higher risk of tissue injury.
Conclusions:
- Surgical suture grip 2 offers superior accuracy compared to grip 1.
- While wavering can improve accuracy with grip 1, it may increase the risk of iatrogenic tissue damage.
- Optimizing grip technique is essential for precise and safe surgical suturing.
