AI Technical Summary

Technical Problem

Conventional collets in robotic surgical systems provide retention in a single direction, leading to movement along the axis, altering the cutting location and imposing a single bending moment, which can cause tool slippage and stress.

Method used

An interlocking collet system with first and second locking members exerting opposing axial forces on an attachment, allowing retention in both directions along the axis and distributing lateral loads to prevent slippage.

Benefits of technology

The interlocking collet system ensures secure attachment retention in both directions, reducing deflection and maintaining uniform angular velocity, enhancing surgical precision and efficiency.
