KEY TAKEAWAY POINTS
- Microsurgery involves the surgeon working at, or just beyond, the threshold of human dexterity as well as beyond the threshold of sensory feedback needed for good control of an instrument
- The diameter of microsurgical instrument handles as well as the applied actuation forces can affect the ease or difficulty of their use
- Surgical instrument handles have been optimized to provide the tool characteristics and attributes important to multiple surgeons from different regions, genders, experience levels, and hand sizes
- By building upon the favorable 360-degree angular orientation, optimized handle diameter and actuation forces, along with increased instrument stiffness, can favorably affect a microsurgical instrument handle’s ease of use in cases requiring fine instrument control
