Abstract: Systems and apparatus for reliably sealing a surgical device are disclosed herein. Specifically, a surgical device including a drive shaft tube that is coupled to a drive shaft is disclosed. Because the drive shaft tube is coupled to the drive shaft, the drive shaft tube rotates at the same rotational speed as the drive shaft, which is less than the rotational speed of a cannulated motor shaft. The drive shaft tube can extend through the cannulated motor shaft. In addition, a sealing member can be provided to seal between the drive shaft tube (which rotates slowly) and the motor instead of between the motor shaft (which rotates more quickly) and the motor. The sealing member can be provided in a gap defined between an outer surface of a portion of the drive shaft tube extending beyond the cannulated motor shaft and the motor.

Abstract: The invention relates to a half shell for a torsion bar bearing (10, 10A), comprising: a half-shell body (1, 1A, 1B, 1C, 1D, 1E) formed in one piece and along a body axis (A); and at least one stiffening device (8, 8A, 8B, 8C, 8D, 8E) adapted to increase a rigidity of the half-shell body (1, 1A, 1B, 1C, 1D, 1E). The invention relates further to a torsion bar bearing (10, 10A) comprising: at least one first half shell and at least one second half shell, wherein at least one of the at least one half shell is disposed opposite to at least one of the at least one second half shell with respect to a torsion bar axis, and to a method of supporting a torsion bar.

Abstract: An external fixation device having a frame comprising at least one rod which takes up the mechanical loads. Frame and bone are connected via connecting means known per se, in particular bone-retaining pins. These connecting means in turn are connected to the frame via clamping jaws. These clamping jaws permit detachable fixing and arbitrary arrangement and grouping on the frame. A module which can be mounted on the frame is provided. By means of the module, a movement of two bone fragments relative to one another can be effected. It has at least two components. The first of the at least two components can be connected to the frame. The second of the two components can be connected to at least one clamping jaw of a connecting means which is connected to a bone fragment.

Abstract: The invention relates to a toolholder (10) for coupling a welding torch to an industrial robot (14), comprising a first fixing device (16) for fixing the welding torch (12) to the toolholder (10) and comprising a second fixing device (18) for fixing the toolholder (10) to the industrial robot (14). The first and second fixing devices (16, 18) can be displaced or repositioned with regard to one another counter to the action of spring elements (22, 24). The toolholder also comprises a protective circuit (26) for deactivating the welding torch (12) when predetermined displacements or repositionings are exceeded. A component (28) connected to the first fixing device (16) can be repositioned in the Z-direction (30) (toolholder longitudinal axis) and can be displaced in the X-direction and/or Y-direction (32, 34) with regard to the second fixing device (18).

Abstract: A pressure gauge device that is operated as a thermal conduction manometer contains a measuring resistor (131) that is arranged in layer form on a self-supporting carrier foil and is in defined thermal contact with a gas whose pressure is to be measured. The thermal contact with the gas is through the carrier foil (11), a thermal conducting layer (123) and optionally through an extra absorber layer (124). The resistance, dependent on gas pressure, of the measuring resistor (131) is detected by a bridge circuit in which each measuring resistor (131) is assigned a reference resistor (136) whose resistance itself is dependent on or independent of pressure.
