A medical device may include a tube having a first end and a second end, in which the first end can engage an instrument tip, an inner shaft disposed in the tube, a shaft end connected to the inner shaft and which can move lengthwise relative to the tube, a first abutment surface to abut a first shaft end stop of the shaft end, and a second abutment surface to abut a second shaft end stop of the shaft end generally opposite the first shaft end stop of the shaft end, in which the shaft end can slidably move along a length constrained by the abutment of the first shaft end stop against the first abutment surface and the second shaft end stop against the second abutment surface, and in which either one or both of the first abutment surface or the second abutment surface is positionally adjustable relative to the tube.

Medical device with adjustable inner shaft movement

A medical device includes a tube end to which a tip having a medical tool is attached. The tip includes a tip housing and a lock tab, as well as a yoke. The tube end includes an outer tube and an inner shaft, in which the inner shaft engages the yoke and the outer tube engages the tip housing. The lock tab fits into a recess in the outer tube to prevent twisting of the tip when engaged with the tube end, and the yoke includes a locking ring to which a spring protrudes, to fixedly and detachably connect the tip to the tube end.
