摘要： The present invention provides a retractor assembly for creating an operative corridor to a spinal surgical target site. The retractor assembly includes a retractable body and a plurality of retractor blades extending generally perpendicularly to the retractor body. The retractor body is operable to separate the plurality retractor blades relative to each other to retract tissue away from the interior of the retractor blades when the retractor assembly is advanced to the surgical target site and the retractor blades are separated to thereby form an operative corridor to the surgical target site. The retractor assembly may also include a supplemental retractor blade assembly attachable to at least two of the plurality of retractor blades, the supplemental retractor blade assembly comprising an elongated supplemental retractor blade and a crossbar connector, the crossbar connector configured to be attached to said at least two retractor blades while engaging the supplemental retractor blade. The retractor body may also operable to splay at least one of the plurality of retractor blades such that a distal end of the retractor blade extends wider than a proximal end of the retractor blade, wherein splaying of the at least one retractor blade is controlled by a gear situated on the retractor body.

摘要： Abstract A method for generating a display of an image of a patient's internal anatomy in a surgical field during a medical procedure is provided. The method includes acquiring a high resolution baseline image of the surgical field including the patient's internal anatomy in a baseline orientation. The method also includes digitally manipulating the high resolution baseline image to produce a baseline image set including representative images of the baseline image at a plurality of permutations of movements of the baseline image from the baseline orientation. The permutations of movements includes movements in at least 4D corresponding to an image in at least 2D. The method also includes acquiring a new image of the surgical field at a lower resolution, comparing the new image to the representative images in the baseline image set and selecting the representative image having an acceptable degree of correlation with the new image, and merging the selected representative image with the new image and displaying the merged image. An image processing device for generating a display of an image of a patient's internal anatomy during a medical procedure is also provided.

摘要： The present invention is directed to a system for monitoring the health of nerves during a spinal surgical procedure. the system comprises a patient module, wherein the patient module comprises at least: a stimulating cathode electrode; an anode electrode; and one or more recording electrodes. The system further comprises a display and a control unit in communication with the display and the patient module. The control unit is configured to: provide an instruction to deliver, via the patient module, a transcutaneous, trans-abdominal stimulation signal to the spine of a patient during or after establishment of an operative corridor, wherein delivery of the transcutaneous, trans-abdominal stimulation signal to the spine is delivered via the stimulating cathode electrode positioned posteriorly on the patient and the anode electrode positioned anteriorly on the patient; determine a stimulation threshold intensity required to elicit at least one neuromuscular response from the transcutaneous, trans-abdominal stimulation signal received via the one or more recording electrodes positioned on the patient; determine the health of the nerves during the spinal surgical procedure based on a comparison of the determined stimulation threshold intensity and a stimulation threshold intensity required to elicit at least one neuromuscular response prior to establishment of the operative corridor; and provide an instruction to display the determined health of the nerves during the spinal surgical procedure via the display.
