In order to flush away local bleeding during surgery with a medical instrument, the instruments are commonly provided with a flushing device. In order to be able to control an inflow and outflow of a flushing liquid, the instruments have a stopcock. In order to achieve the sealing action of the stopcock, the plugs of the stopcock have to be formed with a very high degree of precision. The known production processes for such plugs are very cumbersome and cost-intensive. This provides a plug for a stopcock and a stopcock and a method for producing a plug, by way of which the stated problem is eliminated. This is achieved in that a plug, with a grip part and a cone part, is formed in one part and can be produced in a single process step.

Stopcock, plug for a stopcock, and method for producing a plug for a stopcock

An electrode instrument for use in a resectoscope, the electrode instrument having an elongate shaft portion with two support arms through which a conductor extends that forms an electrode at the distal end of the electrode instrument that can be subjected to high-frequency current and is arranged between the distal ends of the support arms, wherein at least one of the support arms has in its distal end region a tissue contact part for holding tissue fragments that is arranged on the outer wall of the support arm and angled in relation to the longitudinal axis of the support arm; and to a corresponding resectoscope.

Electrode instrument and resectoscope with gripping function

A transporter for a resectoscope for endoscopic surgery, wherein the transporter has a connection body and, for connection to a system component in the connection body, a latch system including an elongate latch element, which is arranged transversely with respect to the longitudinal axis of the transporter and has an engagement opening or an engagement groove, and a spring element, wherein one or more irrigation channels, arranged parallel to the longitudinal axis of the latch element, are formed between latch element and connection body. The invention further relates to a resectoscope for use in endoscopic surgery, wherein it includes a transporter according to one of the preceding claims and preferably a system component latched in the transporter.

Transporter with locking device

A stopcock for a liquid channel of a medical endoscope, having a housing, a spring element and a plug rotatably mounted in the housing, wherein the plug in a working position lies with its conical surface against a seal surface of the housing and can be placed in a medium access position in which the conical and the seal surface have no contact and the housing and the plug remain connected, characterized in that the plug includes one or more transverse grooves, in the outer wall of a conical piece, running transversely to the longitudinal axis of the conical piece and having straight groove bottoms, and the spring element in the medium access position engages with one or more transverse grooves. A medical endoscope having at least one liquid channel, characterized in that it includes at least one stopcock, by which the liquid flow through the channel can be regulated.

Stopcock for an endoscope

A resectoscope for endoscopic surgery with a tubular shaft and a handle, the shaft comprising a longitudinally displaceable electrode instrument and, at its distal end, an electrically insulating insert, the electrode instrument having an elongated shaft section with one or two support arms and, in its distal end region, an electrode that can be acted upon by high-frequency current, characterized in that the insulating insert has one or more guide elements for holding a support arm, the support arm being longitudinally displaceable in the guide element.

Resectoscope with distal electrode guide

A medical endoscope is an instrument having an elongate, tubular shaft. The instrument is commonly provided with a flushing device. The flushing liquid can be guided through corresponding separate liquid channels. In order to be able to control the flow of the liquid, the liquid channels have a stopcock. The stopcocks here are of complex construction, and for this reason both the production thereof and the cleaning thereof are complicated. The invention includes a stopcock and also a housing and a method for producing the housing, by way of which the production and the cleaning of the housing are simplified. This is achieved in that a housing and at least one spring element for form-fitting fixing of a plug in a position in the interior space of the housing are manufactured integrally from a single part, that is to say in one part.

A tap for producing and disconnecting a fluidic connection between at least two connector parts. The tap includes one connecting and disconnecting element, a manual actuating element for rotating the connecting and disconnecting element. The manual actuating element and the connecting and disconnecting element are coupled mechanically. The tap includes a main body having at least one connector part and an interior space for receiving the connecting and disconnecting element, the interior space includes a contact surface for being brought into contact with the connecting and disconnecting element.

Detachable tap having a spring element for fastening and prestressing

The invention relates to an electrosurgical gripping instrument comprising a handle part as well a lower jaw part and an upper jaw part which can perform a forcipate movement. The gripping instrument has a first pair of coagulation sections with a first lower coagulation section on the lower jaw part and a first upper coagulation section on the upper jaw part and, further, a second pair of coagulation sections with a second lower coagulation section on the lower jaw part and a second upper coagulation section on the upper jaw part. Moreover, the electrosurgical gripping instrument has a bipolar pair of cutting electrodes between the first pair of coagulation sections and the second pair of coagulation sections.

Electrosurgical gripping element

A surgical jaw instrument having two jaw pieces mounted at the distal end section of a shaft for relative reciprocal displacement, whereby at each displaced jaw piece a sliding rod is fastened at an incline to the axis of the shaft, to which a displaceable sliding element can be connected parallel to the axis of the shaft in such a way that upon displacement of the sliding element, the jaw pieces are relatively reciprocally displaced wherein a second sliding element is mounted at the first sliding element, diametrically opposed relative to the sliding rod.

Surgical jaw instrument having a slide system

The invention relates to an electrosurgical laparoscopic instrument having an elongated shaft, wherein an end effector is disposed on the distal end of said shaft and a handle is disposed on the proximal end of said shaft. The shaft is designed as a tube through which a rod extends which is coupled to a movable part of the handle and to a movable part of the end effector for actuation by longitudinal movement, and the end effector is connected to the handle via at least one electrical lead. At least one of the leads is disposed in the wall of a hose which is disposed surrounding the rod in the tube.
