A working instrument for use in a resectoscope with a pushing force-transmitting elongated support, whose proximal end area includes an attachment section for attachment in a resectoscope, and whose distal end area carries a working device. The working instrument includes, in its distal end area, a handle element. The handle element projects in a distal direction beyond the support and the working device and is connected to the working instrument so as to transmit pushing forces and can be removed.

Working instrument with handle element for use in a resectoscope, and handle element for a working instrument

A urological resectoscope having an axially extending shaft tube, the proximal end thereof being fixed to a main body. A sliding body is proximally positioned in relation to the main body, and can slide in a parallel manner in relation to the axis thereof. The sliding body includes a receiver, a fixing device and a contacting device. An electrode that can be subjected to a high frequency, including a rigid electrode carrier having one external, insulated conductive wire, can be positioned in the resectoscope such that it can axially slide beyond the distal end of the shaft tube. In the assembly position, the electrode carrier extends through the shaft tube and the main body into the receiver, and can be fixed by the fixing device and contacted by the contacting device. The fixing device is proximally arranged in relation to the contacting device on the sliding body.

Urological electrosurgical resectoscope

The invention relates to an electrode that can be subjected to a high frequency, the electrode including an electrode carrier having at least one external, insulated conductive wire. The electrode is used in a urological resectoscope having an axially extending shaft tube, the proximal end thereof being fixed to a main body. A sliding body is proximally positioned in relation to the main body, and can slide in a parallel manner in relation to the axis thereof. The sliding body includes a receiver into which the proximal end region of the electrode carrier can be introduced. The carrier penetrates the main body and is positioned such that it can slide axially in the shaft tube assembly position in order to fix a fixing section of the electrode carrier via a fixing device pertaining to the sliding body, and in order to contact a first contacting section of the electrode carrier via a first contacting device pertaining to the main body. The fixing section is proximally arranged in relation to the first contacting section.

Monopolar and bipolar electrode for a urological resectoscope

A urological resectoscope having an outer stem fitted with orifices at its distal terminal zone and an inner stem, both stems being tubular and metallic and being sealed from each other in the distal end zone and being affixed to each other, optionally in detachable manner, and to a main case. The resectoscope also includes an electrode support running longitudinally through the inner stem and bearing an hf-loaded cutting loop at its distal end. Liquid hookups feed liquid into the inner stem and drain liquid from an annular duct defined between the inner and outer stems. A distally affixed tubular insulating shell is disposed between the inner and outer stems and affixed to the outer stem.

Urological resectoscope having an insulating case

A urological resectoscope having an axially extending shaft tube, the proximal end thereof being fixed to a main body. A sliding body is proximally positioned in relation to the main body, and can slide in a parallel manner in relation to the axis thereof. The sliding body includes a receiver, a fixing device and a contacting device. An electrode which can be subjected to a high frequency, including an electrode carrier having one external, insulated conductive wire, can be positioned in the resectoscope such that it can axially slide beyond the distal end of the shaft tube. In the assembly position, the electrode carrier extends through the shaft tube and the main body into the receiver, and can be fixed thereto by the fixing device and contacted therein by the contacting device. The contacting device defines an opening of the sliding body, the opening completely cutting through in a transversal direction relative to the receiver, and extends perpendicularly relative thereto, to a depth on the other side thereof. In the contacted state, the contacting device includes a clamping connector that is designed for pivotable clamping on a contact section of the electrode carrier.
