Abstract: A multi-photon optical probe includes a probe housing, a lateral scanning stage coupled to a lateral mirror assembly and a remote axial scanning stage coupled to an axial mirror assembly. The lateral scanning stage is adapted to scan output laser energy over a planar scan area of the sample by moving the lateral mirror assembly. The axial scanning stage is adapted to scan the output laser energy over a vertical depth range of the sample, which, combined with the planar scan area, forms a 3-dimensional volume. A controller operates in conjunction with a number of remote actuating legs coupled to the axial mirror assembly in order to provide level imaging plane which in turn provides for a clear scanned image.

Abstract: A guiding apparatus for x-ray-free screw placement by a spinal posterior approach, comprising an interspinous spacer, a slide scale (1), and an angle-changing rod. The apparatus is simple to operate, easy to grasp, and well accepted by physicians. A reliable effect is provided in screw placement. Significantly reduced X-ray exposure is allowed for patients and medical staff. In a small-incision minimally invasive screw placement operation, even without exposing the spinal ligament, a small spike-like protrusion of a base (2) of the interspinous spacer can ensure accurate interspinous positioning across the skin. This is applicable for both minimally invasive and incision surgeries and has a wide range of uses.
