摘要
A device for preparing the insertion canal for inserting an endoscope for percutaneous nephroscopy includes a tubular member which can be guided on a guide wire inserted through the patient's skin and tissue into the renal calyx. The tubular member carries one or more scalpel blades at its distal end for creating incisions along the path of the wire which can then be expanded to provide a canal for the endoscope. Gripping, orientation and insertion depth indicating means are also disclosed.
