2.7 Cervical Traction Vector

The modular table base is equipped with a cervical traction vector (see Figure 8). The cervical traction vector provides the adjustability of the angle of pull for cervical traction as shown in Figure 9.

Figure 8: Cervical traction vector

2.8 Pulley Assembly

The pulley assembly is permanently attached to the head end column to guide a traction rope. The cervical traction vector attaches to the medial side of the head end H-frame in the mounting holes to achieve the desired angle of traction (see Figure 9). Sandbag weights may be added to provide the appropriate traction load during anterior or posterior cervical surgery or any other time cervical traction is desired. The traction weight is connected to a rope, which passes over the pulley assembly, threads through the pivot shaft of the head end crossbar and connects to the patient traction apparatus (see Figure 10).

MIZUHOSI 2009 NW0504 Rev. D

2.9 Coupling Device Identification

Identify the coupling device on the end of the table top (see Figures 11 and 12). Early versions of the Jackson Spinal Surgery Top and Imaging Tops have fixed mounting tubes. Jackson Spinal Surgery Tops built after October 1999 and Radiolucent Imaging Table Tops built after January 1997 will have gimbal mounting assemblies (Figure 12). Gimbals allow for rotation of the table top when positioned in extreme lateral tilt and trendelenburg or reverse trendelenburg. Both designs couple to the H-frame in the same fashion. The 5890/5891 Modular Table Bases can utilize either version of the coupling devices but the 5892/5803 Advanced Control Bases must use only gimbal mounting assemblies (Figure 12).

WARNING

Use of table tops on the 5892/5803 Advanced Control Bases without gimbal mounting assemblies (Figure 12) can result in damage to the table top.

3.0 TABLE TOP COUPLING PROCEDURES

)

The Jackson Spinal Surgery Top and Radiolucent Imaging Top may be coupled and interchanged to any modular table base, as needed, to provide flexibility and procedural capability.

NOTE: For complete instructions on the modular table base operation and functions, please refer to the appropriate owner’s manual supplied with the Modular Table Base. A thorough understanding of the operation of the 5890 and 5891 Modular Table Base is required before continuing.

3.1 5890/5891 Modular Table Bases

The following instructions are directed toward the use of a table top on the 5890 or 5891 Modular Table Base. These bases do not have the powered lateral tilt function.

3.2 5890/5891 Patient Transfer Safety Lock

Each 5890/5891 Modular Base is equipped with a patient transfer safety lock at both the head and foot end columns. The patient transfer safety lock is actuated by positioning the lever protruding out of the right side of the control box at the head end column (see Figure 13). A second patient transfer safety lock is located on the side of the foot end control box (see Figure 14). When engaged, the patient transfer safety lock prevents rotation of the crossbar by locking the crossbar in the horizontal position.

MIZUHOSI 2009 NW0504 Rev. D

3.3 5890/5891 Rotational Friction Control

The rotational friction control is located at both the head and foot end columns. At the head end, the rotation friction control is the large right-angled lever on top of the head end control box (see Figure 13). At the foot end, the rotation friction control is the black lever that is located on the lower side of the control box (see Figure 15). The rotation friction control may be tightened to act as a friction brake or it can be adjusted to hold the table top at any degree of lateral tilt. As a friction brake, it can be loosened to maintain the desired amount of resistance while still allowing the table top to be adjusted to a different degree of tilt. When completely loose, the rotation friction control will facilitate 180 degree rotations. Rotate the rotation friction control clockwise to increase friction and counterclockwise to reduce friction. It is recommended that the rotation friction control be left in the maximum friction position (fully clockwise) whenever table top movement is not intended.

Crossbar

Figure 15: Foot end column (5890/5891 base shown)

Rotation friction control

NOTE: Because the foot end rotation friction control lever has limited range of movement, occasionally it may not be possible to fully loosen or tighten the brake with one turn of the handle. In that case, once the end of the movement range has been reached, pull the handle down. This will disengage the mechanism and allow the handle to be returned to its starting position without affecting the amount of friction. Repeat the process until the desired amount of friction is achieved.

3.4 Twenty-Five Degree Rotation Stop

Each modular base is equipped with a 25-degree rotation stop. The rotation stop is actuated by the lever located on the left side of the control box near the top of the head end column. It can be easily activated with the left hand when standing at the head end of the table (see Figure 16). When engaged, the rotation stop prevents lateral rotation greater than 25 degrees from the horizontal position. The rotation stop should be left in the engaged position and disengaged only during a 180-degree rotation.

4. Engage the patient transfer safety lock on the head end and foot end columns (see

Figures 13 and 14)

Warning:

For safe patient transfer, the patient transfer safety lock must be engaged prior to transfer in order to prevent the possibility of the table top rotating while the transfer occurs. Failure to do so may result in the patient being dropped.

5. Set the rotational friction control on the head and foot end columns to maximum

friction by fully rotating clockwise (see Figures 13 and 15).

6. Set the 25 degree rotation stop on the head end column (see Figure 16).

Warning:

Prior to coupling the table tops, verify that the two (2) H-frames are properly installed to the crossbar. Confirm the T-pins passes completely through the Hframes and the crossbars and that the T-pin drop locks are in sight and pivot freely. Failure to do so may result in the patient being dropped.

3.6 Selecting The Mounting Holes For The Table Top

When selecting the H-frame mounting hole, it is intended that the center of gravity of the patient be at or below the centerline of the crossbars. For most patients, the fourth open mounting hole below the crossbar is the appropriate position (see Figure 20).

Centerline of crossbars

NOTE: Two people are required to complete the following sequence of actions.

7. Select the appropriate mounting holes on the H-frame to support the table top.

Insert the T-pin into the H-frame on the head end column first. Align the mounting tube on the table top to the selected mounting hole on the H-frame. Push the T-pin through the H-frame, completely through the mounting tube and through the opposite side of the H-frame. The T-pin drop lock should be in sight and pivot freely (see Figure 21).

8. To couple the foot end of the table top, slide the H-frame and crossbar as necessary

to accommodate the length of the table top (see Figure 22). Align the mounting tube on the table top to the selected hole on the foot end H-frame. Push the T-pin through the H-frame, completely through the mounting tube on the table top and through the opposite side of the H-frame. This should be done at the same level as the mounting hole where the head end was coupled. The T-pin drop lock should be visible and pivot freely.

(shown without patient support pads)

3.7 5892/5803 Advanced Control Base

The Jackson Spinal Surgery Top and Radiolucent Imaging Top may be coupled and interchanged to the 5892/5803 Advanced Control Base as needed to provide flexibility and procedural capability. Identify the coupling device on the end of the table top as described in section 2.9, Figures 11 and 12 of this manual.

Warning:

The Jackson Spinal Surgery or Radiolucent Imaging Tops used on the 5892/5803 Advanced Control Base must have gimbals (Figure 12). Earlier versions of these table tops do not have gimbals. Use of table tops without gimbals can result in damage to the table top.

NOTE: For complete instructions on the 5892/5803 Advanced Control Base operation and functions, please refer to the appropriate owner’s manual supplied with the advanced control base. A thorough understanding of the operation of the 5892/5803 advanced control base is required before continuing.

3.8 5892/5803 Table Control Identification

The head end of the 5892/5803 Advanced Control Base is equipped with three indicator lights. These lights are: 1) 180° rotation lock indicator light, 2) tilt drive status light and 3) rotation safety indicator light. Verify that the rotational safety lock switch is in the ON position, and the 180 degree rotation lock lever is in the locked position. All three lights must be illuminated before a patient is transferred to the table.

Figure 24: Indicator lights, head end column 5892/5803 Advanced Control Base

3.9 Rotation Safety Lock Switch

The rotation safety lock switch (with the lighted indicator) locks out the lateral tilt function. This feature is designed to prevent unintended lateral tilt of the table top. The rotation safety lock switch should be turned off only when a 180-degree patient rotation is to be performed. If the rotation safety lock switch is not illuminated, press the rocker switch to the ON position.

3.10 180° Rotation Lock Indicator

The 180° rotation lock indicator light, when lit, indicates the 180-degree rotation lock is engaged and the table cannot be rotated 180 degrees. If the 180-degree rotation lock indicator is not on, rotate the rotation lock lever clockwise until the light is illuminated.

NOTE: If a 180 degree patient rotation is to be performed, the rotation lock lever should be rotated counterclockwise approximately one half rotation past the point that the rotation lock indicator light goes out. Rotating the lock lever to this point lessens the drag of the friction control, thereby allowing the table tops to rotate more freely during the patient rotation. If even less friction is desired, the lock lever may be rotated further, counterclockwise, as necessary.

After the patient rotation is complete, rotate the rotation lock lever clockwise until the rotation lock indicator light is illuminated.

Warning:

When the rotation lock indicator light is not illuminated, the table top is UNLOCKED regardless of how much the lock lever has been rotated clockwise or counterclockwise. Always rotate the lock lever until the rotation lock Indicator light is illuminated after a 180° rotation. If increased friction lock on the rotation is required, rotate handle in a clockwise direction until desired friction is met.

Warning:

All three lights must be illuminated before a patient is transferred to the table. If all three lights are not illuminated, do not transfer the patient until they are illuminated.

MIZUHOSI 2009 NW0504 Rev. D

3.11 Tilt Drive Status Indicator

The tilt drive status indicator light is lit when the power lateral tilt mechanism is in the center position of the +/- 25 degree powered lateral tilt range. If the tilt drive indicator is not illuminated, operate the lateral tilt function using the hand pendant in the appropriate direction until the indicator is lit. The head end crossbar should be horizontal when the tilt drive status indicator is lit. If the head end crossbar is not horizontal, the internal power tilt mechanism is out of synchronization with the crossbar. Refer to the section on synchronizing the lateral tilt function in the 5892 advanced control base user guide or the 5803 owner’s manual, to reset this function.

3.12 Installing The H-Frames

The following coupling procedure assumes the head end and foot end columns do not yet have either the Jackson Spinal Surgery Top or the Radiolucent Imaging Top in place. The coupling procedure for the Jackson Spinal Surgery Top or the Radiolucent Imaging Top is as follows:

1. Lock table base in position by engaging the (4) caster locks.

2. Install an H-frame to head end crossbar and secure with a T-pin (see Figure 25).

Fully retract the head end crossbar against the head end column.

3. Install an H-frame to foot end crossbar and secure with a T-pin (see Figure 26).

3.13 Selecting The Mounting Holes For The Table Top

When selecting the H-frame mounting hole, it is intended that the center of gravity of the patient be at or below the centerline of the crossbars. For most patients, the fourth mounting hole below the crossbar is the appropriate position (see Figure 20).

NOTE: Two people are required to complete the following sequence.

4. Select the appropriate mounting holes on the H-frame to support the table top.

Insert the T-pin into the H-frame on the foot end column first. Align the mounting tube on the table top to the selected mounting hole on the H-frame. Push the T-pin through the H-frame, completely through the mounting tube and through the opposite side of the H-frame. The T-pin drop lock should be visible and pivot freely (see Figure 22).

Warning:

Verify that the T-pin is inserted through the H-frame, passes completely through the table mounting tube, and through the opposite side of the H-frame and the Tpin drop lock is in sight and pivots freely. Failure to do so will result in the patient and table assembly being dropped.

5. To couple the head end of the table top; slide the H-frame and crossbar away from

the foot end (shown in Figure 25) as necessary to accommodate the length of the table top. Select the appropriate mounting holes on the H-frame to support the table top. Align the mounting tube on the table top to the selected mounting hole on the H-frame. Push the T-pin through the H-frame, completely through the mounting tube and through the opposite side of the H-frame. This should be done at the same level as the mounting hole where the head end was coupled. The T-pin drop lock should be in sight and pivot freely (see Figure 21).

A table top completely coupled to a table base is shown in Figure 23.

Warning:

Failure to follow the above prescribed procedures regarding securing the H-frame to the crossbars and the table top to the H-frames may result in the patient being dropped.

5.2.4 Prep and drape the patient in the standard fashion. This position provides ideal access to the anterior cervical spine or ideal access to the anterior lumbar spine through an abdominal approach which gives exposure to the lumbar-sacral area. If the surgeon should desire to laterally rotate (tilt) the patient, carefully follow the directions in section 8.0: Rotation Procedures, depending on which base is used.

The option to perform surgery with the patient in cervical traction is readily available. The Mizuho OSI P/N 5979-1 cervical management system is recommended for this function (see Figure 29).

For anterior lower lumbar spine surgery, the Mizuho OSI P/N 973 or 974 inflatable bladder may be used under the lower back to provide controlled lumbar spine extension.

Upon completion of the anterior surgery, it is possible to rotate the patient to a prone position while maintaining cervical traction and without having to remove the patient from the table (see section 8.0: 180-degree patient rotation).

NOTE: In order to achieve the correct and final position of the pads, it may be necessary to reposition the pads along the table frame after a patient has been transferred. To do so, carefully lift the patient, release the pad locking lever; slide and relocate the pad to the designed position and re-engage the locking lever.

Warning:

Verify that the pad locking levers are latched securely in place. Failure to do so may result in the pad bases breaking when the patient is being transferred on or off the Jackson Spinal Surgery Top.

7.5.3 Apply the GentleTouch® face pillow, chest, hip and thigh pad covers as described in the patient care kit instructions.

7.5.4 Attach either the two leg support sections or the leg sling to the table top. The leg support sections are shown in Figures 36 and 37; the sling is shown in Figure 38.

7.6 Use Of The Leg Sling

The leg sling may be used to support the legs on the Jackson Spinal Surgery Top in place of the leg support sections (see Figure 38). The leg sling can allow for increased hip flexion by allowing the patient’s knees to be lowered below the frame of the Jackson Spinal Surgery Top. When the sling is used, it is recommended not to use the thigh pads as the increased hip flexion angle may increase the pressure on the anterior aspect of the thighs. A patient properly positioned in a leg sling is shown in Figure 43.

Figure 38: Leg sling

The sling should be adjusted for each patient. The straps on the sling consist of a double-sided hook closure that allows for infinite adjustment along the length of the strap. To install the sling, place the sling over the frame of the foot end of the spinal top. Feed the four straps through their respective buckles on the opposite side of the sling and secure. The hook end of the strap may be folded over onto the loop portion of the strap to allow for greater adjustability. The strap may be folded over itself again to shorten it, thereby raising the sling and decreasing the hip flexion angle of the patient.

7.6.1 Place two (2) or three (3) pillows in the leg sling approximately where the patient’s lower legs will rest to help achieve the desired amount of knee flexion. This can also be done when using the leg support sections.
