Abstract: The invention relates to a clamping element for securing a tube, having the following: a first guide and a second guide for receiving a tube, wherein the two guides run towards each other, and the clamping element is designed in such a manner that it is connectable to a pump device such that a tube guide can be formed by the two guides at a pump inlet and pump outlet.

Abstract: Coupling device (1), which comprises at least two connectable elements in the form of a sleeve (2) and a sleeve holder (3), and the sleeve (2) has, at a first side (a), a recess (4) which is configured on both sides as hooks (5) and is provided with bevelled edges (6), and the sleeve holder (3) has, at a second side (c), a horizontally extending through-pin (7).

Abstract: The present disclosure relates to a tube insert for a dialysis liquid line or a hydraulic tubing set, the tube insert including at least one housing; a first connection point for connecting a tube section of the hydraulic tubing set to the tube insert; a second connection point for connecting a second tube section of the hydraulic tubing set to the tube insert; a third connection point for connecting a fluid receptacle to the tube insert; a main line in fluid communication with the first connection point and with the second connection point; a secondary line in fluid communication with the third connection point; and a deflection element for deflecting the liquid, or parts thereof, flowing in the main line out of the flow direction and towards the secondary line.

Abstract: A surgical instrument includes a jaw tool with two branches that can be closed for grasping tissue. In order to transmit the closing force to at least one branch, the branch is coupled with a preferably manually actuatable pull/push element, and, for coupling, an actuating pin that supports a sleeve interacts via the sleeve with a coupling track, in which case the sleeve rolls off the coupling track. In this manner, any deformation, abrasion or burr formation on the coupling track is prevented to such an extent that, even after numerous closing movements of the branches, the branches can still be actuated unimpaired by any wear of the coupling track and the actuating pin, respectively.

Abstract: A conveying device for conveying a medical fluid that is guided into a hose includes a rotor and a stator. The stator includes a stator base, an area for receiving the hose in the conveying device, and a hose bed providing a counter bearing for occlusion devices. The rotor includes a rotor axis and at least two occlusion devices that are attached radially to the rotor axis and that compress the hose intermittently against the hose bed during use of the conveying device. The rotor encompasses an axial guiding element that is arranged to rotate about its own longitudinal axis for aligning the hose in the stator. The longitudinal axis of the axial guiding element extends parallel to the longitudinal axis of the rotor axis. The axial guiding element includes a middle section and a first lateral section protruding radially over the middle section.

Abstract: An instrument including an actuation gear mechanism that provides two functions of a tool. The actuation gear mechanism comprises a cam mechanism and a gear segment mechanism. The circumference of the cam disk of the cam mechanism—in a first section (?1)—is a spiral curve for generating a stroke for closing the forceps tool, while the circumference of the cam disk—in a second, adjoining, angular range (?2)—is circular. When the cam disk with the circular curved line biases the spring means, no further movement takes place on the output of the cam mechanism. Preferably, two congruent cam disks are provided, whereby these—together with the driving gear and the segment gear, as well as the shaft—form a one-piece plastic injection-molded part. The installation space between the cam disks can be utilized for a slide with a gear rack for shifting the knife.

Abstract: An electrosurgical instrument, in particular for argon plasma coagulation, includes a handpiece 10, an electrode (11) connected to the handpiece (10), a shaft (12) which surrounds the electrode (11) and is held in the handpiece (10), and an operating mechanism (13), which comprises at least one rotary knob (14) arranged on the handpiece (10). The shaft (12) is axially movable relative to the electrode (11) and a shear force can be applied to it by operating the rotary knob (14). The handpiece (10) has a brake device which exerts a braking force on the shaft (12), and the operating mechanism (13) forms a transmission gear (15) which is connected to the shaft (12) for transferring the shear force.

Abstract: The invention relates to an electrosurgical instrument, especially for argon plasma coagulation, with a handle (10), an outer shaft (12) that surrounds an electrode and/or an inner shaft (11, 111) and is held in the handle (10), and an actuation mechanism (13) on the handle (10) to move the outer shaft (12) in the axial direction relative to the electrode/to the inner shaft (11, 111). The invention is characterized in that the inner shaft and/or the electrode (11, 111) are mechanically connected with one another in a distal end area (65) of the outer shaft (12) in such a way that the inner shaft and/or the electrode (11, 111) can be bent by moving the outer shaft (12) relative to the inner shaft and/or to the electrode (11, 111).

Abstract: The surgical instrument (10) according to the invention comprises a jaw tool (16) with two branches (20a, 20b) that can be closed for grasping tissue. In order to transmit the closing force to at least one branch (20a, 20b), the branch (20a, 20b) is coupled with a preferably manually actuatable pull/push element (50), and, for coupling, an actuating pin (46) that supports a sleeve (70) interacts via the sleeve with a coupling track (65a, 65b; 66a, 66b), in which case the sleeve rolls off the coupling track (65a, 65b; 66a, 66b). In this manner, any deformation, abrasion or burr formation on the coupling track (65a, 65b; 66a, 66b) is prevented to such an extent that, even after numerous closing movements of the branches (20a, 20b), said branches can still be actuated unimpaired by any wear of the coupling track (65a, 65b; 66a, 66b) and the actuating pin (46), respectively.
