Splayed handle surgical scissors reduce hand fatigue and allow surgeons to apply more force. Their unique ringlet design fits the natural hand posture, improving surgical performance.

Area of Science:

  • Surgical instrumentation
  • Human factors engineering
  • Orthopedic surgery

Background:

  • Conventional surgical scissors can lead to surgeon hand fatigue during prolonged procedures.
  • The design of traditional scissor handles may not align with the natural resting hand posture.

Purpose of the Study:

  • To evaluate the ergonomic advantages of splayed handle surgical scissors compared to conventional designs.
  • To assess the impact of splayed handles on surgeon hand fatigability and applied force.

Main Methods:

  • Comparative analysis of splayed handle versus conventional surgical scissors.
  • Evaluation of handle ergonomics and force application capabilities.
  • Surgeon feedback on comfort and performance.

Main Results:

  • Splayed handle surgical scissors demonstrated a significant reduction in hand fatigability.
  • The ringlet configuration of splayed scissors conforms to the natural hand resting posture.
  • Surgeons were able to apply greater force using splayed handle scissors compared to conventional ones.

Conclusions:

  • Splayed handle surgical scissors offer ergonomic benefits by reducing hand fatigue.
  • The design enhances surgeon's ability to apply force, potentially improving surgical outcomes.
  • This innovation represents a significant advancement in surgical tool design.
