Abstract

A coagulation, washing and suction instrument has a shaft having a washing and a suction canal, by way of which a washing fluid can be supplied to, or removed from, respectively, a bodily cavity. The instrument consists of three detachably connected parts, namely a shaft having a washing and a suction canal; a handle which can be pushed onto, and secured to, the proximal end of the shaft, the handle being made of an insulating material and having a high frequency connector for supplying a coagulation electrode on the distal end of the shaft, and finger pressure releasable connection canals for the supply to, and the removal from, the canals of the shafts, of the washing fluid; and a part for the introduction of auxiliary instruments, which can be coupled proximally to the shaft and to the handle and which can be shut off.
