Bench Testing of an 8 N Slip Resistance Specification for the Handle Shaft Locking Interface of an Articulated Laparoscopic Instrument

Background

Articulated laparoscopic instruments require a reliable mechanical connection between the handle and shaft to maintain the intended instrument configuration during surgical manipulation. The handle shaft locking interface should resist unintended relative displacement under external loading. However, the appropriateness of a specific slip resistance threshold must be evaluated in relation to the instrument design and intended conditions of use.
