An expandable fingers medical device which improves surgical speed and precision and enhances patient care and recovery by minimizing anesthesia time, trauma, infection and iatrogenic complications and increases viability of anastomosis. The medical device has fingers which expand and spread out in response to actuation of a control assembly. In the illustrative embodiment, the control assembly has a wrist mounting which holds the fingers and a wire rope for pulling the fingers against the cammed end of a tube. A threaded rod is secured to the distal end of the wire rope for threaded engagement with an internally threaded knob. When the knob is turned in one direction, the rod and wire rope are pulled causing the fingers to cam against the cammed end of the tube, thereby causing the fingers to spread apart. When the knob is turned in the opposite direction, the rod and wire rope are pushed causing the fingers to retract.

Multi-purpose pneumatic and hydraulic devices suitable for diagnostic and surgical use facilitate surgical procedures as well as enhance patient care and recovery by minimizing trauma, infection and iatrogenic complications. The multi-purpose devices each have at least one medical grade balloon and a stabilizing assembly to enhance positioning and engagement of the balloon in a lumen. The stabilizing assembly can take the form of another medical grade balloon or one or more vacuum responsive members, such as active or passive microsuckers. The multi-purpose device can also be equipped with a self-advancing unit, a bypass circuit, a vacuum retractor, a crusher, a multi-lens system and/or a fiberscope.
