A new articulation mechanism for an endocutter has been designed to allow continuous (non-discreet) articulation of the end-effector up to 50 ° in two directions. However, to support this design an articulation locking mechanism needs to be developed. This mechanism should be capable of locking the end-effector at any position. Additionally, this mechanism must withstand external loading applied to the end-effector to prevent the mechanism from de-articulating unintentionally. The mechanism (s) chosen to achieve this must fall within the existing constraints of fitting through the 12mm trocar and around the existing knife design. Additionally, in order to be compatible with the endocutter handle, the articulation mechanism must be driven by a single push / pull linkage.
