  • Publication number: 20160120554
    Abstract: A targeting system for aligning an axis of a targeting sleeve and a bore in a distal end portion of an intramedullary nail is proposed, the targeting device comprising a distal targeting arm with a first end being configured to be coupled to a trailing end of an intramedullary nail, an adjusting device, the adjusting device being configured to be coupled to the distal targeting arm. The adjusting device may comprise an adjusting element and a nail follower including two targeting holes each being configured to receive a sleeve assemply. The adjusting element may cooperate with the nail follower such that the positions of the two targeting holes are adjustable so as to correspond to respective locking holes at a leading end of the intramedullary nail, even when the nail is bent.

  • Patent number: 9265541
    Abstract: A system is proposed including an intramedullary nail with a longitudinal nail axis, a first lateral portion, a second lateral portion opposite to the first lateral portion, and a longitudinal bore. The nail has a locking hole arrangement having a first bore being formed in the first lateral portion and a second bore being formed in the second lateral portion. An axis of the first bore and an axis of the second bore are arranged with an offset from each other, and are arranged so that a locking member such as a screw may frictionally engage within both the first bore and the second bore.

  • Patent number: 9220534
    Abstract: An implantation pin kit and a method for implanting an implantation pin includes a cannulated implantation pin having a channel and a heating device. The channel of the pin extends in a longitudinal direction of the pin and connects a proximal opening at a proximal end of the pin with a distal opening at a distal end of the pin. The channel of the pin and the heating device are adapted such that the heating device can be accommodated within at least a portion of the channel of the pin. The heating device is adapted to thermally heat material comprised in at least one of the pin and the heating device. Thereby, meltable material of the pin can be liquefied or additional liquefied meltable material can be inserted into the pin and the liquefied material can then be push towards and out of the distal opening in order to augment and fix the implantation pin in a target structure.

  • Patent number: 8728134
    Abstract: An implantation pin for implantation in a target structure has a pinhead and a shaft. The pinhead comprises a pinhead moulding portion comprising a moldable material which can be liquefied by application of mechanical energy such as ultrasonic vibration energy. A channel extends through the pinhead and the shaft, the channel connecting the pinhead molding portion to a discharge opening located at the shaft. The moldable material can be liquefied by applying mechanical energy in the form of ultrasonic vibrations via a fixation device including an ultrasonic sonotrode and a vibrating tip. The pressure applied by the vibrating tip can be transmitted via the border of the pinhead to the target structure while the liquefied mouldable material can be forced through the channel and the discharge opening into a gap between the implantation pin and a recess in a target structure thereby fixing the implantation pin in the target structure.

  • Patent number: 8425518
    Abstract: A bone reamer has an ablation device for forming cavities in body tissue, the ablation device is movable with respect to a head of the reamer, and is capable of protruding at least partially beyond a surface of the head. The amount of protrusion the ablation device protrudes beyond the surface of the head has a variable geometry and the geometry is remotely modifiable. More particularly, the amount the ablation device extends beyond the outer surface of a reamer head body can be varied by an actuator located on the reamer outside the body.

  • Publication number: 20060018770
    Abstract: A valve includes a housing having an inlet, an outlet and a ram receiving chamber. A ram has a first end and a second end and is slidably supported in the ram receiving chamber. The ram has a central pin on the second end of the ram. An actuating element is connected to the ram. A plate is fixedly connected to the housing. The plate has a central bore. The plate and the ram selectively abut to form a valve seat. The inlet is in fluid communication with the ram receiving chamber. The ram has an outer wall. Fluid communicates between a portion of the ram receiving chamber adjacent to the first end of the ram and a portion of the ram receiving chamber adjacent to the second end of the ram. In the closed position, the ram abuts with the plate. The pin protrudes through the central bore in the plate. In the open position, the actuating element displaces the ram such that the ram is spaced from the plate.
