Abstract
PURPOSE: To make the exchanging of end pieces easy and facilitate operations during surgical operation by providing a vent hole to the outer frame of the fixing seat of the condenser lens fixed to the end piece provided to the end part of the laser light transmission device of a laser knife device.
CONSTITUTION: The holder is so constituted that the gas 8 fed therein through a gas lead-in terminal 7 passes through the vent hole 21 provided to the frame part of the lens holder 2 and blows to the outside through the protruding part of an end piece 1. This obviates the deposition of the flood and fume flying at the incision on a condenser lens 3 and lets the condenser lens 3 be cooled. In the case of replacing the end piece 1, only required is to remove the end piece because no gas lead-in terminal is provided on the end piece side and this eliminates the laborious operation of once removing the hose of the gas lead-in terminal and remounting the same.
