  • Publication number: 20240099782
    Abstract: A bone clamp including two or more clamping members configured to clampingly receive a bone therebetween. The bone clamp further includes a basis supporting at least two of the clamping members at a first distance to each other. At least one of the at least two clamping members has a body and is rotatably supported by the basis. The at least one rotatably supported clamping member has a bone engaging structure extending helically along at least a part of a length of its body. The bone engaging structure is configured to engage a side surface of the bone upon rotation of the at least one rotatably supported clamping member. Depending on the direction of the rotation, the rotatably supported clamping member advances along the side surface of the bone either in a downward direction for mounting the bone clamp or in an upward direction for dismounting the bone clamp.

  • Publication number: 20230117183
    Abstract: Navigation system and method for tracking movement of a patient during surgery. Image data is acquired by imaging the patient with a base layer of a skin-based patient tracking apparatus secured to the patient's skin. The skin-based patient tracking apparatus includes a plurality of optical surgical tracking elements. A computer processor arrangement is adapted to implement a navigation routine. The patient position is registered to the image data. The movement of the patient is tracked based on movement of the plurality of optical surgical tracking elements. The movement of the patient's skin is tracked by determining positions of the optical surgical tracking elements both before and after a deformation of the skin-based patient tracking apparatus. Movement of the patient's skin results in corresponding movement of the surgical tracking elements to provide a dynamic reference frame for use in continuously tracking movement of a patient's skin during surgery.

  • Publication number: 20230010275
    Abstract: Disclosed is a method for use in surgical navigation, the method being performed by a computing system. A first pose of a first tracker is determined in exactly four degrees of freedom, DOF, and a second pose of a second tracker is determined in exactly four DOF. Based on the first pose and the second pose, a third pose of a virtual tracker may be determined in six DOF. The virtual tracker has a fixed spatial relationship relative to the anatomical object in the six DOF of the third pose. A transformation between the third pose and a fourth pose of the anatomical object in six DOF in an image coordinate system of image data of the anatomical object may be determined or obtained. The present disclosure further relates to a computing system, a surgical navigation system and a computer program product.

  • Publication number: 20220087773
    Abstract: An optical tracker and a surgical device. The surgical device includes a shaft defining a longitudinal axis. The shaft has a first shaft portion configured to be inserted into a patient, and a second shaft portion configured to be located outside the patient when the first shaft portion is inserted in the patient. The surgical device further includes an actuation member actuatable relative to the first shaft portion, and an operation member operable relative to the second shaft portion. The operation member is configured to actuate the actuation member when being operated. Further, the surgical device includes a tracker coupled with the operation member so that operation of the operation member causes the tracker to move relative to the shaft, such as to rotate around the longitudinal axis.

  • Patent number: 10165981
    Abstract: A surgical navigation system is disclosed including a camera that is fixedly attached to a patient. The camera space merges with the patient space and thereby eliminates the need for a separate patient tracker. The surgical navigation system calculates the position of a surgical tool with a tracking device in view of the camera and shows on a display device the position of the surgical tool with respect to the patient superimposed and in correlation with a scan image of the patient.

  • Patent number: 9387008
    Abstract: A surgical trajectory guide to guide a medical device to a pivot point has a base that can be attached to a patient, an axial guide member connected with the base and aligned with a pivot point along a first axis in fixed relation to the base and a second axis perpendicular to the first axis. The guide member has a longitudinal axis, and is connected to the base such that the longitudinal axis always passes through the pivot point, and the axial guide member is prevented from rotating around the longitudinal axis. The guide further has at least one electronic angle sensor that can automatically sense a first angle of the axial guide member relative to the local gravity vector about the first axis and a second angle of the axial guide member relative to the local gravity vector about the second axis without having to level the base.

  • Patent number: 9248000
    Abstract: 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.
