  • Publication number: 20220189657
    Abstract: A power tool has a drive unit and an operating handle. At least one electrical line connects the operating handle and the drive unit to each other. The at least one electrical line is fastened at a first electrical connection location to the operating handle and at a second electrical connection location to the drive unit. A safety cable extends along the at least one electrical line between operating handle and drive unit. The safety cable has a first end section and a second end section. The first end section is connected mechanically fixed at a first fixation location to the operating handle. The second end section is connected mechanically fixed at a second fixation location to the drive unit. The at least one electrical line and the safety cable are guided together such that the safety cable forms a tear-off protection for the at least one electrical line.

  • Patent number: 9029139
    Abstract: Methods for generating and using omentum cells, and particularly stromal cells and/or omentum stem cells, in medical treatments such as tissue repair and regeneration to facilitate healing from traumatic injury to an abdominal organ, and immune modulation treatments such as suppression of immune responses and inflammation and prevention of tissue fibrosis. According to one aspect, a medical procedure is performed on a patient that involves harvesting omental tissue from the patient, and then transferring the omental tissue to an organ of the patient. At least a portion of the harvested omental tissue may be activated prior to transferring the omental tissue to the organ. Alternatively, the transferred omental tissue may comprise non-lymphoid cells isolated from the omentum tissue and obtained by homogenizing at least a portion of the harvested omental tissue.

  • Publication number: 20120156412
    Abstract: A method for reinforcing a substrate having a hollow structure or for fixing an insert in such a substrate comprises introducing a one- or two-component expandable and curable preparation based on epoxy resin into a selected part of the hollow structure to be reinforced. The preparation cures by being heated to a temperature in the range from 20 to 100° C. or above, while being expanded. An epoxy resin prepolymer and an organic ammonium carbamate, which at a temperature in the range from 20° to 100° C. or above releases at least 25% of the CO2 bound as carbamate.

  • Patent number: 4854317
    Abstract: In an applicator for C-shaped scalp clips with applying instruments in the form of a movable edge and a stationary edge and with a retaining element for the scalp clips, the moved edge can be brought closer still to the stationary edge while the retaining element is fixed in its open position. When the direction of motion is reversed, the movable edge immediately takes the retaining element back with it into its locking position. The movable edge is thus coupled with the pivotable retaining element by a slip coupling.

  • Patent number: 4592498
    Abstract: A stapler, particularly for suturing skin wounds or incisions, is disclosed which comprises a channel in which a driver is advanced by a slide in the direction of an anvil surface. A staple magazine which extends substantially parallel with the driver includes a curved section which opens into the channel to deliver staples into the channel for engagement by the driver. During forward displacement of the driver, a projection on the driver presses a leaf spring to which the anvil surface is connected. The anvil surface at the forward end of the leaf spring is thereby brought into its operating position and is automatically moved back into its retracted position upon release of the spring after the driver is retracted. The curved section in the staple magazine enables the stapler to have a slim profile which does not obscure the working area during a stapling operation. After completion of a stapling operation, the anvil surface is automatically retracted from a closed, implanted staple.

  • Patent number: 4569505
    Abstract: In order to simplify production of clip removing forceps used to bend open skin clips, it is suggested that one of the two branch elements encircles the other in the shape of a U in the region of pivotal connection, that one of the two branch elements bears on its side walls facing the other branch element projections arranged at the axis of rotation, that the other branch element has circular recesses to accommodate these projections, that the projections have a circular cross section corresponding to that of the recesses, whereby two opposite side faces of these projections are flattened, and that a groove runs from the circular recess to the edge of the other branch element, the width of this groove corresponding at least to the distance between the flattened sides of the projections but being smaller than the diameter of the circular recess and this groove being aligned such that, in the operating position of the two branch elements, the curved side portions of the projections rest at least partially on c

  • Patent number: 4505273
    Abstract: A surgical staple is disclosed comprising an arcuate central region which can be flattened by a stapling tool. Straight legs extend obliquely upwardly from the central region to which are connected downwardly extending side portions. The side portions are curved substantially in the form of an arc of a circle having a center at the center for the central region. When the central region is flattened, the side portions move about an arc of a circle so that automatic puncture channels are produced. Tearing of tissue is thereby prevented.

  • Patent number: 4316470
    Abstract: An approximator for anastomotic surgery having two parallel guide bars connected rigidly at one end to a fixed clamp holder. Another clamp holder is displaceably guided on the guide bars. One of the guide bars is a meshing bar non-rotatably mounted to the fixed clamp holder. A driver is mounted on the displaceable clamp holder rotatably about an axis crossing the longitudinal axis of the meshing bar and is formed with a toothed gear engaging the driving bar, the latter and the toothed gear forming a rack and pinion gearing.

  • Patent number: 4124195
    Abstract: A control valve for a pulsating rocket engine comprises a valve seat and a movable valve part, one of which has a facing surface, of a non-deformable material, having a plurality of concentrically arranged saw-tooth shaped sealing ridges with flat sealing faces at their apices which extend perpendicular to the movement direction or force application direction. The other valve part has a facing surface of polytetrafluorethylene or polyamide which is initially smooth and plain but which, upon the first closing operation of the valve, responsive to a pressure load thereon exceeding a predetermined pressure load, is irreversibly deformed by the saw-tooth shaped sealing ridges, with flat sealing faces, of the other valve part to form therein grooves complementary to the sealing ridges.

  • Patent number: 4116200
    Abstract: A surgical milling tool with a hand-operated milling machine for milling the heads or sockets of bone joints of spherical shape is disclosed. The tool is formed of a hemispherical cup integrally formed with a cylindrical skirt and flange and is provided with a plurality of openings of semi-oval shape, each having a cutting edge arranged at the minor axis of the oval shape. The openings are situated such that, upon rotation of the cup, the cutting edges thereof overlap to provide a continuous cutting edge surface conforming generally to the shape of the cup.
