Lithotripsy apparatus using a flexible endoscope

An apparatus, comprising:

• an endoscope including:
• a flexible shaft which has an active deflection section at a distal tip;
• a handle connected to a proximal end of the flexible shaft oriented at an angle with respect to the longitudinal axis of the proximal end of a straight portion of the flexible shaft;
• a platform mechanism mounted to a top portion of the handle and oriented substantially in line with the longitudinal axis of the proximal end of a straight portion of the flexible shaft to provide a straight entry into a working channel of the flexible shaft for an output accessory;
• and
• a lithotripsy shaft wherein the lithotripsy shaft is insertable into a proximal end of the working channel for breaking UP a stone at the distal end of the flexible shaft of the endoscope by protruding therefrom and passing energy to the stone,
• wherein the platform mechanism is movable along the longitudinal axis between a deployed position and a retracted position,
• wherein a stone retrieval device is insertable into the proximal end of the working channel of the endoscope for retrieval of a stone at the distal end of the flexible shaft of the endoscope by protruding therefrom,
• wherein the lithotripsy shaft is provided with one or more guide features at a distal end of the lithotripsy shaft to facilitate passage of wires or filaments of the stone retrieval device therethrough.
