ProAxis® Spinal Surgery Table Owner’s Manual

2 Introduction

2.1 General Description

The ProAxis® Spinal Surgery Table (Figure 1) is designed to support and position a patient undergoing surgical procedures while allowing for the articulation of the patient’s spine intra-operatively through flexion and extension movements. These intra-operative movements allow the natural movement of the spine to be replicated during the surgical procedure. The table provides prone, supine, and lateral positioning capabilities, with enhanced user and patient benefits through key proprietary features. The table’s radiolucent hinge, spars, and two-piece supine top also allow for excellent intraoperative imaging using either a C-arm or O-arm®.

The ProAxis® table has electrically powered positioning and operating functions, which are controlled by means of the IntelliPendant®. The IntelliPendant® provides a visual status display for the Floor Locks, Hinge Mode, Advanced Control Pad System™ (ACP), Battery Status, Height Status, Trendelenburg/Reverse Trendelenburg Angle, Hinge Angle, and Lateral Tilt Angle. The table provides a further feature in providing the user with the option of selecting between two Hinge Mode settings – Fixed Surgical Site (FSS) or Fixed End (FE) mode.

The table includes Mizuho OSI Tempur-Pedic® medical pad technology. The material used in the manufacture of the Mizuho OSI pads has viscoelastic properties and is temperature sensitive, becoming softer where the patient’s body makes the most contact with the surface and remaining firm in the areas where less body contact is being made. Pressure is distributed evenly over the entire surface area. The pads are radiolucent and made without natural rubber latex. The benefits of using Mizuho OSI TempurPedic® Medical Pads are improved pressure management, reduced shear forces, and enhanced patient comfort when used in ambient temperatures. In accordance with AORN recommendations, it is important to limit skin exposures to lower ambient temperatures, protect the patient by initiating passive warming interventions (e.g. applied forced-air warming systems, blankets, drapes and reflective composites), and to maintain an ambient room temperature of 20° to 25°C.

The Advanced Control Pad System™ is utilized when the patient is positioned prone. The pad control system, which is built into the table, is electronically controlled and pneumatically actuated, providing massage action and periodic pressure point stimulation through the Contoured ACP Hip Pads.

4 Basic Operation

4.1 Control Operation

For use with AC power:

1.Plug the Power Cord into a properly grounded receptacle. Refer to the manufacturer’s label at the Foot-End column for input voltage requirements (Figure 10, page 18).

NOTE: Only use the Power Cord supplied by Mizuho OSI with the table or if necessary, one of equivalent rating.

2.Depress the Power Switch and observe that the switch illuminates with a green ring indicating that power is applied to the table.

3.If the AC power cable is not connected to an outlet with a protective earth ground, then the external ground stud should be connected to a protective earth ground (Figure 4, page 13).

WARNING: This symbol indicates an external ground stud that is required for use when the AC power cable is not connected to a protective earth ground hospital grade AC outlet in your operating room or facility or when the table is in use under battery power. Failure to ensure ground may cause harm to the patient, healthcare professionals, or the device.

NOTE: If the integrity of the AC power source is in doubt, the equipment shall be operated from its internal electrical power source (battery).

Should the table be operated on battery power:

1.Ensure that the battery has been properly charged as outlined in Section 12.3. Depress the Power Switch and observe that the switch illuminates with a green ring indicating that power is applied to the table. The battery LED at the base of the Head-End column will not be illuminated, indicating that the table is being used on battery power (Figure 4, page 13).

2.The battery status symbol on the screen of the IntelliPendant® indicates the level of charge in the batteries. If the battery status symbol with one green bar appears , the battery is not charged and the table should only be used with AC power.

WARNING: Failure to ensure the table is properly charged when used on battery power may cause the table to malfunction and may harm the patient, healthcare professional and the table.

3.To protect the patient, hospital staff, and the table from possible electrical hazards, an external ground cable connection is required between the external ground stud and protective earth ground when the table is in use under battery power (Figure 4, page 13).

The expected working life of a fully charged battery is approximately eight (8) hours with two procedures averaging a total of six (6) minutes of motion time. While in storage, it is recommended that the table be plugged in to charge the battery. A fully depleted battery will take 24 hours to fully charge. This can be accomplished when using the table under AC power.

If during use, the battery symbol on the IntelliPendant® appears , the table should be connected to AC power, and it can continue to be utilized while the battery is charging.
