Surgical resectoscope for use by manufacturer of urological instrument, has shaft with distal end region arranged at proximate end of conveyor, flushing system producing flow of liquid in shaft, and sensor monitoring movement of electrode

摘要

#CMT# #/CMT# The resectoscope (1) has a rigid tubular shaft (2) with a distal end region (3) e.g. ceramic ring, arranged at a proximate end of a conveyor (5) that controls movement of an electrode (12) longitudinally arranged in the distal end region of the shaft. The electrode is arranged in an imaging region of a rod-shaped elongated optic (9) arranged in the shaft. A flushing system produces flow of liquid in the shaft, where the flushing system comprises a controlled irrigation pump (P). A motion sensor e.g. proximity sensor (16), monitors movement of the electrode. #CMT# : #/CMT# The shaft is designed as a metallic tube. An independent claim is also included for a method for controlling a flushing system of a surgical resectoscope. #CMT#USE : #/CMT# Surgical resectoscope for use by manufacturer of a urological instrument. #CMT#ADVANTAGE : #/CMT# The flushing system produces flow of liquid in the shaft, and the motion sensor monitors movement of the electrode, thus reducing bubbles in the liquid and reducing purge stream to provide continuous turbidity in the liquid, and hence achieving better visibility without increasing consumption of washing liquid. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a surgical resectoscope.
