Extraction device for extracting a foreign body from a patient

A percutaneous nephrolithotomy device, the device comprising:

• a handle having a base, a proximal lever extending from a first end portion connected to the base to a second end portion, and a distal lever extending from a third end portion connected to the base to a fourth end portion that is spaced a distance away from the second end portion of the proximal lever, where the distal lever includes a pair of spaced apart legs including a first leg spaced a gap distance away from a second leg, with a first end of the first leg and the second leg connected to the base and a second end of the first leg and the second leg connected to the fourth end portion of the distal lever;
• a transmission mandrin having a proximal end connected to the proximal lever and a distal end adapted to be connected to a kidney stone extraction tool;
• and
• a stiffener having a tube connected to a retainer, with the tube providing a lumen sized to receive the transmission mandrin and the retainer having a channel sized to receive the transmission mandrin;
• wherein engagement of the retainer into the gap distance between the pair of spaced apart legs attaches the stiffener to the handle.

• a transmission mandrin slideably engage with the end portion of the distal lever and having a proximal end connected to the proximal lever and a distal end adapted to be connected to a kidney stone extraction tool;
• and
• a stiffener having a tube connected to a retainer, with the tube providing a lumen and the retainer having a channel sized to receive the transmission mandrin, with the transmission mandrin inserted into the lumen of the tube and the retainer inserted between the pair of spaced apart legs and attached to the end portion of the distal lever.

• a sheath connected to the end portion of the distal lever;
• a transmission mandrin inserted into the sheath and having a proximal end connected to the proximal lever and a distal end adapted to exit the sheath and connect with a kidney stone extraction tool;
• and
• a stiffener having a tube connected to a retainer, with the tube providing a lumen and the retainer having a channel sized to receive the transmission mandrin, with the transmission mandrin and the sheath inserted into the lumen of the tube and the retainer inserted between the pair of spaced apart legs and attached to the end portion of the distal lever.
