An intramedullary nail for distracting a long bone, comprising a first tube extending in an axial direction of the intramedullary nail, a second tube extending in an axial direction of the intramedullary nail, which is coupled with the first tube to be axially displaceable within one another, a first locking opening in an end area of the first tube facing away from the second tube, and a coil, which is disposed in a coil area of the first tube between the first locking opening and the second tube.

Intramedullary nail for distracting a long bone

Medullary pin () for a distraction with segment transport and subsequent lengthening of a tubular bone, wherein the medullary pin () comprises: an at least partly hollow body () extending in an axial direction of the medullary pin (), a locking means for locking the body () in a first end fragment () of the tubular bone, a first inner part (), which is arranged displaceably in the axial direction inside the body () and comprises a first fixation means for the fixation of a middle fragment () of the tubular bone, a second inner part (), which is arranged displaceably in the axial direction inside the body and comprises a second fixation means for the fixation of a second end fragment () of the tubular bone, and a drive unit () for the axial displacement of the first inner part () relative to the second inner part (), wherein the drive unit () is arranged inside the body () between the first fixation means of the first inner part () and the second fixation means of the second inner part ().

Medullary pin

Intramedullary nail for distraction of a long bone with an at least partially hollow shank extending in an axial direction of the intramedullary nail, locking element for locking the shank in a first bone fragment of the long bone, a first inner section which is arranged in axially movable manner within the shank and has a through hole orientated in the radial direction for accommodating a segment bolt for fixing a bone segment of the long bone, wherein the shank has an elongated hole in the area of the inner section for passing through of the segment bolt, an actuator for axially moving the first inner section, wherein a second inner section is arranged within the shank so as to be axially movable.

Intramedullary nail

A medical device for determining the position of intracorporeal implants such as fixation systems, plates or the like, comprises at least one impedance-measuring device and an ultrasound device which are both connected to at least one intracorporeal probe, the impedance-measuring device being additionally equipped with at least one connector for connection to the implant. The device is suitable for determining the position of pedicle screws and the like in a spinal column fixation system with metal rods as stabilizers.

Medical device for determining the position of intracorporeal implants

A growing prosthesis comprising a joint replacement part, a prosthesis stem, a stem-anchoring element, and an element with corresponding drive provided for the lengthening of the growing prosthesis. The element provided for the lengthening of the growing prosthesis is a spindle element arranged in the stem-anchoring element.

Growing prosthesis

A planetary roll system, in particular for a device for extending bones. The system comprises two elements that can be displaced in opposition to one another and that are interconnected by at least one drive element. A hosing is designed to receive at least one planetary roll which comprises at least one radial cavity.

Planetary roll system, in particular for a device for extending bones

A distraction assembly for the plastic surgery of the face, for correcting the upper and/or lower jaw, for example for removing an overbite, a cross bite, a cleft palate or for bridging bone structure that was removed by, for example, surgery, consists of a device with at least two elements which are axially moveable in relation to each other. The device can be completely implanted subcutaneously and can be indirectly or directly actuated without contact, especially by energy inductively supplied from outside.

Distraction assembly

An intromedullary nail for the distraction of bone parts consists of two elements which can be moved relative to one another. At least one electrically operated driving element which is supplied by electrical energy to move the two elements relative to one another is connected to the medullary nail by at least one detachable plug-in element.
