Extractor with handle

摘要

A rigid extractor (10) is revealed, a rigid device for use in percutaneous procedures to remove kidney stones directly from the kidneys. The rigid extractor (10) uses a handle (16) fixed to an outer rigid cannula (12), and an inner cannula (14) to control an extraction device (18) that may be removable from the inner cannula (14). The extractor (10) is desirably used with a fluoroscope, in which the surgeon maneuvers the extractor (10) with the aid of a view of the operating field provided by the fluoroscope. The surgeon then maneuvers the extractor (10) to grasp the kidney stones and remove from the patient. The extractor (10) may also be used with a nephroscope. The device may be used with a removable extraction device (18) such as a basket, a grasper, a pair of jaws, or a pair of scissors.
