A miniature articulating tip for an endoscopic instrument comprising a jaw with a curved slot through which two pivot lugs pass and are anchored in or integral to a fixed outer tip. The two pivot lugs guide the jaw over a path defined by the curved slot and provide stops at the ends of the curve.

Dual pin and groove pivot for micro-instrument

A detachable and replaceable end effector assembly. The detachable mechanism is made of standard end effectors attached to an actuating tip and pinned inside a yoke assembly. Replacement is made by pulling back a spring loaded radial lock 90, to disengage two rear tabs 51 on the outer tip 50. The yoke assembly is then rotated 90 degrees to disengage the rear yoke pin 9 from the tubular shaft 70. This rotation of 90 degrees also unlocks the T-bar 45 from the front 'T' slot of the long actuator 80. The end effector or jaw assembly is then free to be pulled away from the remainder of the shaft. In addition there is a bayonet connection to hold the parts together and prevent accidental disconnection.

Surgical instrument with replaceable jaw assembly

A handle-activated retrograde endoscopic instrument with an extension shaft rotatably connected to a fixed handle, the rotation limited by a spring-loaded lock into shaft detents corresponding to rotational position options, and with an extension of an outer tip and reduction of open range of effector movement to shield any pinch area.
