Description

BACKGROUND

The present disclosure relates to surgical tables and, more particularly, to a surgical table configured to facilitate accessing a surgical site of a patient positioned on the surgical table during lateral spine surgery.

Generally, during lateral spine surgery, the disk space is removed and the implant is inserted while the patient is in a lateral position. The patient is then transferred to a prone position for the placement of stabilizing rods and screws. However, when the surgeon tries to insert the stabilizing rods and screws, the table under the patient blocks access to properly placing the rods and screws. Accordingly, the patient needs to be positioned on the side of the table. By positioning the patient on the side of the table, the patient is no longer centered on the table causing interferences with the C-Arm and the table. Additionally, surgeons would prefer if the abdomen of the patient were to fall away from the surgical site to allow for the internal organs to remain out of the way during placement of the implants. Moreover, problems exist with the stability of the patient while in the lateral position. Tape is often used to secure the patient in the lateral position and often times the tape is not enough to properly keep the patient from shifting during surgery.

The inner rod 34 is telescopically attached to the outer rod 32 so that the inner rod 34 is moveable from a retracted position and an extended position relative to the outer rod 32. In the extended position, the rod 30 has a length that is greater than a length of the rod 30 in the retracted position. The inner rod 34 is moveable to any intermediate length between the extended position and the retracted position. A nut 36 positioned on an end 38 of the outer rod 32 is tightened to secure the inner rod 34 relative to the outer rod 32. The rod 30 is adjustable in length 40 to adjust a distance between the head end lift column 14 and the foot end lift column 16. Accordingly, a distance between the head end lift column 14 and the foot end lift column 16 is adjustable to accommodate different length table tops 20.

Each lift column 12 includes an inner column 50 that extends upward from the base 22. An outer column 52 is telescopically positioned on the inner column 50. The outer column 52 is adjustable relative to the inner column 50 to adjust a height of the outer column 52. That is, the outer column 52 may be raised and lowered relative to the inner column 50. For example, FIG. 1 illustrates the outer column 52 of the head end lift column 14 at a first height 60, and FIG. 2 illustrates the outer column 52 of the head end column 14 at a second height 62 that is greater than the first height 60. It should be appreciated that the outer column 52 is positionable at a height less than the first height 60 or greater than the second height 62. It should also be appreciated that the outer column 52 is positionable at an intermediate height between the first height 60 and the second height 62. While FIG. 2 only illustrate the outer column 52 of the head end lift column 14 raised to the second height 62, one of skill in the art will recognize that a height outer column 52 of the foot end lift column 16 may also be adjusted by raising or lower the outer column 52 of the foot end lift column 16. Accordingly, the respective outer column 52 of each of the head end lift column 14 and the foot end lift column 16 may be adjusted to the same height to maintain the table top 20 in a level, horizontal position. Likewise, the respective outer column of each of the head end lift column 14 and the foot end lift column 16 may be adjusted to different heights to positioned the table top 20 at an angle, as illustrated in FIG. 2. In some embodiments, the lift columns 12 may include an actuator to raise and lower the outer column 52.

By aligning the patient's hips with the hip indicia 500, a surgical site of the patient is aligned with the notches 120 in the center member 110 to enable access to the surgical site, when the patient is positioned on the surgical table 10. Additionally, properly aligning the patient's hips with the hip indicia 500 facilitates aligning the retention pads 200 (described in FIG. 7) against the patient's chest, back, and thigh, respectively. The hip indicia 500 is positioned on each side member 112 to enable facing the patient in either direction on the surgical table 10. In the exemplary embodiment, the hip indicia 500 is positioned on an end 502 of the side members 112 adjacent the leg section 102 of the table top 20.

Referring to FIG. 4, an actuator 170 is positioned below the torso section 146 of the patient support surface 140. The actuator 170 is positioned between the patient support surface 140 and the table top 20. In some embodiments, the actuator 170 is an inflatable bladder. It will be appreciated that other forms of actuators may be included, such as a cam mechanism. The actuator 170 is configured to move the torso section 146 of the patient support surface 140 between a lowered position, shown in FIG. 1, and a raised position, shown in FIG. 4. The actuator 170 may also move the torso section 146 of the patient support surface 140 to a position between the lowered position and the raised position. The actuator 170 raises the torso section 146 of the patient support surface 140 so that the top surface 154 of the torso section 146 is at angle of up to and including 15 degrees relative to the top surface 156 of the head section 142 and the top surface 158 of the leg section 144. In the raised position, a slope 180 is formed in the patient support surface 140 between the head section 142 and the leg section 144. Notably, when the torso section 146 is in the raised position, the side member pads 150 are not moved, but rather, remain stationary. The torso section 146 may be raised or lowered to position a spine of a patient in an appropriate position for a surgical procedure.

FIGS. 5 and 6 illustrate operation of the actuator 170. It should be noted that FIGS. 5 and 6 illustrate the side members 112 in a stowed position (described in FIG. 7); however, the actuator 170 may be operated with the side members 112 in any position. The actuator 170 is positioned between the torso section 146 of the patient support surface 140 and the torso section 104 of the table top 20. In a lowered position, shown in FIG. 5, the top surface 154 of the torso section 146 of the patient support surface 140 is substantially flush with the top surface 156 of the head section 142 and the top surface 158 of the leg section 144 of the patient support surface 140. In a raised position, shown in FIG. 6, the torso section 146 of the patient support surface 140 is lifted off of the table top 20 by the actuator 170. Accordingly, a space 480 is created between the torso section 146 of the patient support surface 140 and the table top 20. The raised actuator 170 is positioned with the space 480.

The actuator 170 may be configured to raise the torso section 146 of the patient support surface 140 to any intermediate position between the lowered position and the raised position. The actuator 170 raises the torso section 146 of the patient support surface 140 so that the top surface 154 of the torso section 146 is at angle of up to and including 15 degrees relative to the top surface 156 of the head section 142 and the top surface 158 of the leg section 144. In the raised position, or any intermediate position, the slope 180 is formed in the patient support surface 140 between the head section 142 and the leg section 144. The angle of the slope 180 is dependent on the degree to which the actuator 170 raises the torso section 146 of the patient support surface 140.

Referring now to FIG. 7, the side members 112 are illustrated in a stowed position that enables access to a surgical site of the patient.
