An ultrasound imaging probe for real time 3D ultrasound imaging from the tip of the probe that can be inserted into the body. The ultrasound beam is electronically scanned within a 2D azimuth plane with a linear array, and scanning in the elevation direction at right angle to the azimuth plane is obtained by mechanical movement of the array. The mechanical movement is either achieved by rotation of the array through a flexible wire, or through wobbling of the array, for example through hydraulic actuation. The probe can be made both flexible and stiff, where the flexible embodiment is particularly interesting for catheter imaging in the heart and vessels, and the stiff embodiment has applications in minimal invasive surgery and other procedures. The probe design allows for low cost manufacturing which allows factory sterilized probes to be disposed after use.

The present invention may be embodied as a system for MIS training. The system comprises a processor, a communication device, and a first input device in communication with the processor. The processor is programmed perform any or all of the described disclosed methods.

A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention component whose primary functions are to prevent migration of the load bearing device and loss or migration of graft material from within the load bearing device. A secondary function of the retention component is to address fixation of fasteners when the surgeon is confronted with a challenging access to adequate boney structures due to excessive curvature / angulation of the vertebrae column, minimal invasive surgery techniques, danger to surrounding vascular or neurological tissues, poor bone quality, or similar surgical complications. A tertiary function of the retention component is to provide better alignment and stabilization of misaligned vertebrae when spondylolisthesis is a significant factor. One or more fasteners secure the retention component to each of the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion.

The present invention may be embodied as a method of minimally-invasive surgery (“MIS”) training wherein a simulator having a display, a computer, and a first input device, is provided. A video of an MIS is displayed on the display, and a first surgical tool is visible in at least a portion of the video. A match zone corresponding to a position on the first surgical tool is determined. A computer-generated virtual surgical tool (“CG tool”) is superimposed on the displayed video. The CG tool is selectively controlled by the first input device. A target position of the CG tool is determined. If the target position is not determined to be within the match zone, further steps may be taken. For example, the video may be paused, a message may be displayed to the operator, or the computer may signal the input device to move to a position such that the target position is within the match zone.
