ABSTRACT:
A lens exchanger for a laser surgical tool is disclosed. This lens exchanger installs easily between the coupler for the laser source and the surgical tool (such as a laparoscope). The lens exchanger protects the lens on the surgical tool from contamination by water vapor, smoke and debris. The lens exchanger can be configured to provide clear windows so the surgeon can conveniently switch to a clean lens during surgery as needed. The lens exchanger can also be configured with lenses that change the focus of the laser cutting beam, making the cutting spot more or less focused as required by the particular application.
