clutch mechanism
Safety feature in laparoscopic instruments that disengages cutting or energy functions.
Full Definition
A built-in safety mechanism in advanced laparoscopic instruments that allows surgeons to temporarily disengage the active function (cutting, coagulation, or grasping) while maintaining instrument control. This feature is particularly important in energy-based devices and robotic surgical systems, where accidental activation could cause serious tissue damage. The clutch mechanism provides an additional layer of safety during critical dissection phases or when repositioning instruments near vital structures.
Usage
Usage note: Often used in robotic surgery contexts; distinguish from mechanical locking mechanisms.
In Context
- "The surgeon engaged the clutch mechanism while repositioning the instrument near the ureter." — operative report
