Resectoscope device

Claim 1

A resectoscope device comprising: a sheath body having an elongated hollow sheath to be inserted into a urethra; a handle part having a slider connected to said sheath body and sliding in the axial direction; an observing scope inserted into said hollow sheath through said handle part and said sheath body; an electrode means inserted through said hollow sheath, removably connected at the rear end to said slider, said electrode means having a resecting part for projecting out of and retreating into a beak opening at a tip of said hollow sheath by a sliding operation in the axial direction of said slider, said electrode means having a forked part bent upward at a large angle with the axial direction of a shaft part of said electrode means, and a forward portion of said forked part being inclined forward and upward at a small angle with the axial direction with respect to said shaft part of said electrode means, said shaft part being inserted through said hollow sheath so that, when said resecting part is to be retreated into said beak opening, said forked part will be narrowed and displaced upward by said sliding operation in a rearward direction so that said forked part is housed in contact with an inner upper peripheral surface of the beak above the center axis of the sheath body to prevent said resecting part from catching on an inner lower peripheral surface of the beak; and a stabilizer provided in said electrode means, said stabilizer being formed so that said observing scope can be inserted therethrough.
