Systems and methods for surgical imaging are disclosed herein. A head-mountable device (HMD) can include a display configured to provide an image within a field of view of an environment of the HIVID. At least one fiducial marker can be arranged on a surgical patient. At least one sensor can be configured to track a position of the at least one fiducial marker. Three-dimensional image information indicative of one or more internal features of the patient is provided. Based on information from the at least one sensor, a position of the surgical patient can be determined. Based on the determined position of the surgical patient, the HIVID can display at least a portion of the three-dimensional image information superimposed on at least a portion of the surgical patient within the field of view.

In an embodiment, a method for effecting thermal therapy using an in vivo probe includes positioning the probe in a volume in a patient, identifying an irregularly shaped three-dimensional region of interest and automatically applying thermal therapy to the region using the probe. Applying thermal therapy may include identifying a first emission level at a first rotational angle based in part on a depth of a radial portion of the region in the direction of probe emission, activating emission of the probe, causing rotation of the probe to a next rotational angle, identifying a next emission level at the next rotational angle based in part on a depth of a radial portion of the region in the direction of probe emission, activating emission to deliver therapeutic energy, and repeating rotation and emission until therapeutic energy has been delivered to the volume.

Systems, methods and devices are described herein for performing a navigated surgical procedure involving a patient's anatomy in sterile and non-sterile surgical environments. A camera may be used to determine a registration of the camera coordinate-frame to the patient anatomy or optionally a tracker in relation to the patient anatomy. A drape may be applied to permit use in a sterile surgical environment. The camera may be moved from its original position to enable access to patient anatomy while maintaining a registration of the camera coordinate-frame with the patient anatomy. Alternatively, the camera may be used in a hand-held or head-mounted manner. A visualization of the patient anatomy may be displayed on a computing unit, with visualization reference planes defined by the pose of an instrument or the camera. The visualization may be presented on a display of a computing unit or as part of a head mounted augmented reality system.

A surgical instrument positioning system includes articulating arms for coarse adjustment and a micro manipulator connectable to the articulating arms for fine adjustment. The micro manipulator selectively holds the surgical instrument and is operable to adjust the position of the surgical instrument. The micro manipulator includes two adjustment assemblies for providing linear adjustment and two adjustment assemblies for providing rotational adjustment. Features of the system also provide for control of the amount of free movement or play within the micro manipulator. Also a stop feature works in conjunction with the adjustment assemblies to maintain the tip of the instrument at an intersection of the two rotational axes facilitating rotational adjustment of the micro manipulator without linear displacement of the instrument tip.

The present invention relates to a surgical skull clamp (1) and a method for the manufacture of a surgical skull clamp (1). In one embodiment of the surgical skull clamp (1) at least a part of the surgical skull clamp (1) has at least two different structures.

A connector includes a first housing having a bore hole terminating in a machine taper tunnel, a tapered hole, and a slot extending through the first housing across its bore hole to its tapered hole. Similarly, a second housing has a bore hole, a tapered hole, and a slot extending through the second housing across its bore hole to its tapered hole. A rod disposed in the first and second housings' bore holes extends across the slots. The rod terminates at first and second ends with the second end being coupled to the second housing. The rod has a machine taper coupled thereto between its first and second ends for engagement with the machine taper tunnel. A lever, pivotally coupled to the rod's first end, can simultaneously cause the rod's machine taper to move relative to the machine taper tunnel and cause the width of the slots to change.
