DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(15) A tabletop sagittal adjustment device is generally indicated by the numeral 10 in FIGS. 1-8. The adjustment device 10 can be integrated with a surgical table 12, and the adjustment device 10 can be manipulated during surgery to adjust the position of a patient P thereon. In doing so, the adjustment device 10 can be used to alter the position of the patient P before and during surgery to, for example, manipulate the spine of the patient. To illustrate, the adjustment device 10 can be used to facilitate changing of the spinal alignment of the patient P. Furthermore, for example, altering the position of the patient can be used to accommodate different surgical pathways to the spine of the patient P. Thus, before and during surgery, the adjustment device 10 can be used to position the patient P in a first position, and then the adjustment device 10 can be used to reposition the patient P in a different position via manipulation of the adjustment device 10.

(16) The adjustment device 10 includes a first patient support portion 14 and a second patient support portion 15 positioned on top of a base plate 18 of the surgical table 12. The first and second patient support portions 14 and 15 are provided over an upper surface 20 of the base plate 18, and the base plate 18 and the upper surface 20 thereof are spaced apart from the ground by a base portion 22 thereof. The upper surface 20 can be spaced from the ground at a height to accommodate performance of surgery on the patient P.

(17) The first and second support portions 14 and 15 can have various shapes to accommodate positioning portions of the body of the patient P thereon. As depicted in FIGS, 1-8, for example, the first and second support portions 14 and 15 are generally rectangular, and include upper surfaces 16 and 17, respectively, for supporting the patient P thereon.

(18) The patient P, as depicted in FIGS. 2-5, is positioned on the upper surfaces 16 and 17 of the first and second patient support portions 14 and 15, respectively, in a lateral position. As discussed below, the first and second patient support portions 14 and 15 are supported by and moveable over the upper surface 20 of the base plate 18. Thus, using the first and second support portions 14 and 15, the patient P can be positioned and repositioned before and during surgery. In doing so, the patient P can be positioned in various lateral positions to, for example, manipulate the spine of the patient P and/or adjust the surgical pathways to the patient's spine. To illustrate, FIGS. 2 and 3 shows the patient P in a lateral position with the patient's legs straightened to facilitate lordosis in the patient's spine, FIG. 4 shows the patient P in a lateral position manipulated to apply kyphosis to the patient's lumbar spine, and FIG. 5 shows the patient P in a lateral position manipulated to apply additional lordosis to the patient's lumbar spine.

(19) A handle 24 can be attached to one of first and second patient support portions 14 and 15 to facilitate movement of at least one of the first and second patient support portions 14 and 15. As depicted in FIGS. 1-8, for example, the handle 24 is attached to the first support portion 14. As discussed below, the handle 24 serves as a lever arm facilitating repositioning of at least the first support portion 14. Additionally, lower surfaces 26 and 27 of the first and second support portions 14 and 15 can be provided with omnidirectional movement mechanisms. For example, the lower surfaces 26 and 27 can include omnidirectional casters or rollers (not shown) that afford movement of the first and second support portions 14 and 15 in any direction on the upper surface 20 of the base plate 18.

(20) As discussed above, the first and second support portions 14 and 15 are supported by and moveable over the upper surface 20 of the base plate 18. Furthermore, at least one of the first and second support portions 14 and 15 can be moveably attached to the base plate 18. For example, as depicted in FIGS. 6-8, the first support portion 14 and the second support portion 15 are pivotally attached to the base plate 18 by pins 30 and 32, respectively. The pins 30 and 32 are received through holes in the first and second support portions 14 and 15, and removably inserted into holes 34 and 36 provided in the base plate 18. By pinning the first and second support portions 14 and 15 to the base plate 18, the first and second support portions 14 and 15 can pivot about the pins 30 and 32, respectively, to afford the movement depicted in FIGS. 1-8. The holes 34 and 36 are sized to afford constrained movement of the pins 30 and 32 relative thereto, and thus, provide fixed pivot points for the first and second support portions 14 and 15, and the handle 24 can be used in pivoting the first support portion 14, as depicted in FIGS. 7 and 8. Furthermore, the first and second support portions 14 and 15 can be unpinned from the base plate 18 to facilitate unconstrained movement thereof on the upper surface 20.

(21) FIGS. 9-11 depict another embodiment of the surgical table generally referenced by the numeral 12. The surgical table 12 also includes first and second support portions 14 and 15 of the adjustment device 10, and the first and second support portions 14 and 15, as depicted in FIGS. 9-11, are pinned to the base plate 18 using larger holes 40 and 42. The holes 40 and 42 can be formed in the base plate 18 or a second base plate 44 positioned between the base plate 18 and the first and second support portions 14 and 15. The second base plate 18 can also be used with the surgical tables 12 and 12. The holes 40 and 42 are sized to receive and afford semi-constrained movement of the pins 30 and 32 relative thereto, and thus, provide variable pivot points for the first and second support portions 14 and 15. Again, the handle 24 can be used in pivoting the first support portion 14, as depicted in FIGS. 10 and 11, and the first and second support portions 14 and 15 can be unpinned from the base plate 18 to facilitate unconstrained movement thereof on the upper surface 20.

(22) FIGS. 12-14 depict another embodiment of the surgical table generally referenced by the numeral 12. The surgical table 12 also includes first and second support portions 14 and 15 of the adjustment device, and the first and second support portions 14 and 15, as depicted in FIGS. 12-14, are pinned to the base plate 18 using a channel 46. The channel 46 is sized to receive and afford semi-constrained movement of the pins 30 and 32 relative thereto, and thus, provide variable pivot points for the first and second support portions 14 and 15. Again, the handle 24 can be used in pivoting the first support portion 14, as depicted in FIGS. 13 and 14, and the first and second support portions 14 and 15 can be unpinned from the base plate 18 to facilitate unconstrained movement thereof on the upper surface 20.

(23) Additionally, in each of the embodiments of the surgical table 12, 12, and 12, the first and second support portions 14 and 15 can be provided with locking mechanisms for restraining movement of the first and second support portions 14 and 15 after positions therefor have been selected. Furthermore, the upper surfaces 16 and 17 of the first and second support portions 14 and 15 of each of the embodiments of the surgical table 12, 12, and 12 can provided with cushioning to provide relatively soft surfaces for supporting the patient P. For example, the cushioning can be integrated with the upper surfaces 16 and 17, and/or the first and second support portions 14 and 15 can be provided with attachment points to which removable cushioning can be attached. Either way, each of the embodiments of the surgical tables 12, 12, and 12 can be provided with relatively soft surfaces for supporting the patient P thereon,

(24) Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
