Abstract: A trocar with a trocar sleeve, comprising a valve device arranged at the proximal end of the trocar sleeve and comprising a trocar pin which can be inserted axially into the trocar sleeve through the valve device and which has a hollow shaft and a tapering transparent distal tip. An endoscopic optical unit, such that the adjacent body tissue can be observed through the distal tip, can be introduced into the hollow shaft of the trocar pin, and a proximal insufflation connection allows a gas to be introduced into the trocar sleeve.

Abstract: A clamp adapter for a catheter that has a clamp body that receives an elastomeric clamp bushing. In order to fix a catheter inserted into the clamp bushing, the clamp bushing is axially compressed by a clamp lid. For this purpose, the clamp lid is moved axially on the clamp body with a clamp lever by means of a slotted guide.

Abstract: An apparatus for the application of bone cement is described having a housing that comprises a cylinder for the reception of the bone cement. The apparatus further comprises a piston arranged in a longitudinally displaceable manner in the cylinder, by which the bone cement can be pressed out of an exit aperture formed in the cylinder, wherein the piston is longitudinally displaceable in the cylinder by a screw movement to apply the bone cement under high pressure. The apparatus can be switched between the displacement of the piston by the screw movement and a direct displacement in the longitudinal direction without a screw movement. Furthermore, a cannula for such an apparatus is described.

Abstract: A light pointer (16) is mounted on the proximal end of a cannula (10) by use of an adapter (14) for positioning the cannula (10) that is inserted into a body by use of an ultrasonic head. The light pointer (16) emits a light beam (18) in a direction axially parallel to the cannula (10). When the cannula (10) is inserted, the light beam (18) produces a light spot on the bodily surface on which the ultrasonic head is placed.

Abstract: A catheter set for the epidural or peripheral nerve blockade, in which a flexible catheter (20) includes a stimulation tip (22) for the localization and positioning of the catheter tip by electro-stimulation. A reinforcing stylet (40) is introducible in the catheter (20). The axial position of the reinforcing stylet (40) in the catheter (20) is so selected that the distal end area (b) of the catheter (20) is un-reinforced and remains flexible.

Abstract: A flap valve for a trocar system including a valve housing (12) that is proximally attachable to a guide tube (10), a lead-through opening (30) formed in the valve housing (12), and a pivotally mounted flap valve (46). The flap valve (46) is manually pivotable from a “closed” position to an “open” position via a slide rod. The slide rod (52) is mebedded in the body (12), is radially slidable and contacts with its inner end an actuation area of the flap valve (46).

Abstract: A tension adapter for a catheter is disclosed, in which a wire is arranged for electrical stimulation. The tension adapter tensions the catheter by means of a hollow cylindrical elastic tensioning piece (26) which is axially flattened. A contact lug (24) is proximally connected to the tensioning piece (26), into which the proximal end of the catheter extends, whereby the outwardly-bent wire on the catheter comes into contact with the contact lug (24). The contact lug (24) comprises an electrical lead running to the exterior.

Abstract: A catheter for neural blockades in anesthesia includes a flexible plastic tube in which a wire is arranged for electro-stimulation. The distal end of the wire is conductively applied to a contact tip protruding out of the catheter. The contact tip comprises a stopper and a cap which are positioned in the catheter, the cap being arranged in front of the distal end of the catheter and covering the edge of the front surface thereof.

Abstract: The invention concerns a device for anchoring a filter (50) and a catheter (40), comprising an adhesive bandage (10), a securing element (20) for anchoring the catheter (40) and a carrier element (30) for anchoring the filter (50), wherein either the securing element (20) or the carrier element (30) is applied to the adhesive bandage (10), and wherein the securing element (20) includes a first coupling element, which is releaseably connectable with a second coupling element provided on the carrier element (30).

Abstract: The invention relates to a catheter (10) for neural blockades in anaesthesia. Said catheter consists of a flexible plastic tube in which a wire (16) is arranged for electrostimulation. The distal end of said wire (16) is conductively applied to a contact tip protruding out of the catheter (10). Said contact tip consists of a stopper (12) and a cap (14) which are positioned in the catheter (10), the cap being arranged in front of the distal end of said catheter (10) and covering the edge of the front surface thereof.

Abstract: A continuously conductive unipolar cannula for anesthesia is described with an electrically conductive cannula tube (10), with a tip (14) at the distal end and a body part (18) at the proximal end. The cannula tube (10) is provided with an outer electrically insulating covering, which leaves exposed only an end area (16) of the distal tip (14). In the area of the body part (18), an electrically contacting connection (22, 24, 26) for electro-stimulation is provided, which is provided radially on the outer circumference of the cannula tube (10). The body part (18) includes a guide inlet opening (32, 34) axially aligned with the cannula tube (10), through which a catheter can be introduced in the cannula tube (10). Alternatively, an injection hose or a needle can be connected to the body part (18).
