A surgical device for bending an implant is described. The device comprises first and second mould members adapted to at least partially receive the implant between them, wherein the mould members are shaped in three dimensions in accordance with one or more cranio-facial features. The device further comprises an actuation mechanism adapted to convert a manually exerted force into an actuation force acting on at least one of the mould members to bend the implant received between the mould members.

A technique of registering image data of an object 112 with at least one of a location and an orientation of the object 112 is provided. A method embodiment of this technique comprises the step of providing three-dimensional image data generated for the object 112, the image data being representative of at least a portion of the object 112 and of reference markings 130 associated with the object 112. The reference markings 130 have a known spatial relationship with a registration tracker 122 adapted to be tracked by a navigation system 100. The method further comprises providing registration tracking data representative of at least one of a spatial location and a spatial orientation of the registration tracker 122 and providing object tracking data representative of at least one of a spatial location and a spatial orientation of an object tracker adapted to be tracked by the navigation system. The object tracker 124 has a fixed spatial relationship with the object 112. In a next step, the method calculates from the registration tracking data and the object tracking data for a given point in time the relative position between the registration tracker 122 and the object tracker 124. Than, registered image data is generated representative of at least one of the location and the orientation of the object 112 taking into account the spatial relationship between the reference markings 130 and the registration tracker 122 on the one hand and the relative position between the registration tracker 122 and the object tracker 124 on the other.

A bone anchor (10) for use in an orthopaedic procedure comprises a bone fixation portion (12) provided with a plurality of fixation openings (14), the fixation openings (14) each being adapted to receive a fixation device for fixing the bone fixation portion (12) to a bone of a patient, and a device attachment portion (20) provided with a first attachment opening (26) and a second attachment opening (28), the first attachment opening (26) and the second attachment opening (28) being connected to each other by a solid stabilizing portion (36) and being adapted to receive an attachment device for attaching the device attachment portion (20) to an orthopaedic device (24).
摘要:
Ein chirurgisches Elektrowerkzeug weist eine Betätigungsbaugruppe auf, die einen Kraftsensor sowie einen Schalter umfasst. Der Kraftsensor ist zur Ermittlung einer vom Benutzer aufgebrachten Betätigungskraft vorgesehen, und der Schalter wird durch die Betätigungskraft von einem ersten Schaltzustand in einen zweiten Schaltzustand überführt. Eine kombinierte Auswertung des Kraftsensorsignals und des Schaltzustands ermöglicht beispielsweise eine Plausibilitätsprüfung zur Erhöhung der Funktionssicherheit des Elektrowerkzeugs.

A bone plate (10) for use in a surgical, in particular an osteotomy surgical procedure comprises a fixation portion (16) provided with at least one opening (22) adapted to receive a fastening device for fastening the fixation portion (16) to a bone (12) of a patient. A guiding portion (42, 44) of the bone plate (10) is provided with a guiding edge (46, 48) for guiding a bone cutting instrument (50) during the surgical procedure, wherein the guiding portion (42, 44) is removably connected to the fixation portion (16), and wherein the fixation portion (16) and/or the guiding portion (42, 44) has/have a size and shape which are customized based on anatomic data of the patient.
摘要:
A navigation system includes a display monitor, a CPU, and a camera, wherein the camera is mounted to a back side of the display monitor to form a monitor unit. One or more reference units are placed on a body while acquiring an image data set, and are tracked during a surgical operation by the monitor unit to register and correlate a position of a visual image of an exterior surface of the body with the image data set including information concerning internal structures of the body. The image data set is displayed on the display monitor superimposed in registration over the visible image of the exterior of the body with an angle of view and aperture in accordance with the actual position of the camera, whereby the display monitor displays the internal structures corresponding to the line-of-sight of the camera and the observer.
