Resectoscope and electrode assembly

摘要

The present invention relates to an improved resectoscope which enhances versatile and ergonomic operating and handling performance thereof. The resectoscope includes a plurality of thumb engageable portion's a central block assembly used to displace an electrode from a sheath of the resectoscope. Also disclosed is a drip guard assembly which coacts with the outer sheath and is releasably retained in any one of a plurality of positions on the outer sheath so as to accommodate different operations and patients. Additionally, provision is made for improved electrode guiding and stabilizing structures which enhance stability of the electrode assembly by facilitating easy and correct insertion of the electrode without requiring disassembly of resectoscope components.
