Estimating the term…
A resectoscope has an elongated shaft tube, an elongated optic arranged therein with a lens at the distal end and an electrode assembly, wherein the electrode assembly in turn includes an electrode arranged at the distal end of the arms of a fork assembly, which are arranged on opposing sides of the lens and are brought together in a transition region to an electrode shaft, wherein the electrode assembly can be extended in the longitudinal direction by a stroke length from a first position, in which the electrode is arranged inside the shaft tube in front of the lens, into a second position in which the arms of the fork assembly protrude out of the shaft tube. The length of the arms of the fork assembly is thereby greater than 1.2 times the stroke length. The electrode assembly is configured correspondingly.
A resectoscope comprising an elongate shaft tube, an elongate optic arranged therein with an objective lens at the distal end and with an electrode assembly, wherein the electrode assembly comprises an electrode arranged at the distal end of the arms of a fork assembly, which are arranged on opposite sides of the objective lens and are brought together in a transition region to an electrode shaft, wherein the electrode assembly can be deployed in the longitudinal direction by a stroke length from a first position, in which the electrode is arranged inside the shaft tube in front of the objective lens, to a second position, in which the arms of the fork assembly protrude from the shaft tube, wherein the length of the arms of the fork assembly is greater than 1.2 times the stroke length.
An electrode assembly for use in a resectoscope, in which the electrode assembly can be deployed in the longitudinal direction by a stroke length, comprising an electrode arranged at the distal end of the arms of a fork assembly, which are brought together in a transition region to an electrode shaft, wherein the length of the arms of the fork assembly is greater than 1.2 times the stroke length.
