Modified needle holder grips improve suturing in difficult surgical sites. This study determined optimal grips and needle movements for restricted horizontal and vertical suturing fields, enhancing surgical precision.

Area of Science:

  • Surgical techniques
  • Biomechanics of surgical instruments

Background:

  • Needle holder grip modifications are used for suturing in awkward surgical sites.
  • The correspondence between needle holder movement and needle orientation can be compromised by modified grips.

Purpose of the Study:

  • To determine the range of motion for three modified needle holder grips.
  • To identify optimal suturing methods for various operating spaces (horizontal, vertical, restricted, open).

Main Methods:

  • Quantified needle holder range of motion for three modified grips.
  • Evaluated suturing methods in simulated restricted horizontal and vertical operating fields.

Main Results:

  • Oblique grip: 90-degree counterclockwise rotation; Rotated grip: deviation without range alteration; Combined grip: intermediate effect.

  • Optimal grip and needle range vary based on operating space orientation and restriction.
  • Oblique grip offers the most stable needle grasping.

    • Conclusions:

    • Specific needle holder grips and ranges of motion are optimal for restricted horizontal and vertical surgical fields.
    • Understanding grip mechanics is crucial for efficient suturing in challenging anatomical locations.
