EXPEDIUM System PedigreePowered Instruments for the EXPEDIUM System build upon more than ten years of clinical experience with the comprehensive EXPEDIUM 5.5 System, delivering refined instrumentation, which enables surgeons to unlock the full potential of the EXPEDIUM Platform.

Ergonomics and HealthInstrument length is designed to improve surgeon ergonomics and to provide a more comfortable shoulder and torso positioning during the procedure. Additionally, the powered handpiece reduces the number of repetitive motions that can lead to surgeon fatigue or overuse injuries1.

Speed and EfficiencyThe application of Powered Instruments offers potential timesaving for each screw implant. The greatest cumu lative benefit is expected during deformity procedures.

AccuracyThe power handpiece is designed to facilitate steadier hand positioning during pedicle preparation and screw delivery, potentially reducing the off-axis motion associated with manual pedicle preparation and screw delivery.

The Powered Instruments for EXPEDIUM® Spine System enable powered drilling, tapping, and screw delivery with a cordless handpiece, Quick Coupling attachment, and optimized instrumentation.

FEATURES AND BENEFITS

Surgical Technique Powered Instruments for EXPEDIUM 5.5 Spine System DePuy Synthes 1

BiomechanicsThe Powered Instruments for the EXPEDIUM 5.5 Spine System were developed in close collaboration with deformity surgeons having ergonomics in mind. Through optimization of instrument length and geometry, shoulder, elbow, and trunk positioning is improved when compared to manual instrumentation.

During pedicle preparation and screw delivery, Powered Instrumentation allows the surgeon to maintain a low shoulder position, an elbow position close to the torso, and decreases the amount of lateral bending often seen when using manual instrumentation. Maintaining alignment of the torso while minimizing the extension of the upper extremities provides an opportunity to reduce muscle recruitment and surgeon fatigue.

Similarly, using Powered Instruments reduces the number of repetitive motions required during spine surgery, reducing energy expenditure and decreasing the potential for musculoskeletal disorders associated with overuse1.

Before surgery, ensure the batteries of the handpiece are fully charged.

Warning: Only use the Synthes Universal Battery Charger II (05.001.204) to charge the batteries. Using another charger can damage the battery.

1. Charging the batteryPlace the battery to be charged in the proper direction into the corresponding slot of an empty charger bay. Only one battery can be charged in each charger bay at a time. All charger bays can, however, be used simulta-neously with any combination of battery types.

Once the battery types have been identified, the charging process starts automatically. This is signaled by the yellow charger display (Fig. 1).

Depending on the charge status and type of battery, it can take from about 15 minutes to around 60 minutes to charge.

Once the battery is fully charged, the green display lights up and the charger switches to maintenance charge (Fig. 2). The battery can be left in the charger. Leave the device switched on to ensure that the battery is always fully charged.

If the battery is removed from the charger before the green display lights up, it will not be fully charged.

Note: For additional instructions on the use of the Universal Battery Charger II, please refer to the Synthes Universal Battery Charger II Instructions for Use.

2. Inserting the battery in the battery casingTo ensure sterility, the battery is to be inserted into the battery casing by two people, one of whom is wearing sterile garments:

The person with the sterile garments holds the sterile battery casing. If the casing is not opened, the same person presses the central button to unlock (Fig. 1), turns the lid sideways (90°) as indicated by the arrow (Fig. 2) and pulls to open (Fig. 3). Leave the locking mechanism swung outward.

The person wearing the sterile garments places the sterile cover on the battery casing (Fig. 4) and checks if it is seated correctly. The sterile cover ensures that the unsterile battery does not contact the outside of the sterile casing.

The person not wearing sterile garments carefully guides the unsterile battery through the sterile cover (Fig. 5). As an orientation, the two symbols on the battery and the sterile cover should face each other (Fig. 6). The same person presses it completely into the battery casing to ensure a correct seat (Fig. 7). This person may not contact the outside of the battery casing.

The person not wearing sterile garments grasps the flanges on the sterile cover and removes it from the battery casing (Fig. 8).

The person wearing the sterile garments closes the casing cover from the outside without contacting the battery or the inside of the casing. After having closed the casing cover, turn the lid sideways (90°) until it locks.

Precautions:• Normally, one battery is sufficient for one surgery.

A second battery pack (battery casing with the battery) should be kept ready to ensure fast intraoperative changing of batteries under sterile conditions if necessary.

• Never open a battery casing intraoperatively to insert a new battery. Always replace the whole battery pack with another battery pack, which should have been prepared before the start of the surgery.

• If the unsterile battery contacts the outside of the casing, the casing must be resterilised before being used in the OR.

• To close the casing cover, press it firmly to ensure that it is completely closed (Fig. 9 and 10) so that the locking mechanism properly engages. Always ensure that the cover is totally closed before using the system.

• Sterilize the sterile cover after each use to ensure aseptic conditions when inserting the unsterile battery into the sterile battery casing.

Inserting the battery pack into the power toolGuide the battery pack (battery casing with inserted battery) from below into the shaft of the handpiece (Fig. 11). The shape of the battery casing prevents the battery from being inserted incorrectly. Check if the battery pack is seated correctly by gently pulling on it.

Removing the battery pack from the power toolSimultaneously press the release buttons for the battery casing with one hand (Fig. 12) and use the other hand to remove the battery pack from the handpiece.

5. Speed and Rotational Direction Control Mode selector switch 1 in the ON positionThe bottom trigger 2 gradually controls the forward speed (up to approx. 384 rpm with the Quick Coupling for DHS/DCS® Triple Reamers 532.015). When the bottom and top triggers 2 and 3 are pressed at the same time, the tool operates in reverse. The top trigger 3 can be depressed first. Depressing the bottom trigger 2 with the top trigger already depressed will ensure the tool will start in reverse and allow for precise speed control. The speed of rotation may be controlled by how much depression is placed on trigger 2 . When the bottom trigger 2 is released, the tool immediately stops.

Note: The Colibri II offers an oscillating mode ( ) which is not recommended for use with the Powered Instruments for EXPEDIUM 5.5 Spine System.

Clear the surrounding soft tissue and bony anatomy to allow for full screw angulation.

Tap design incorporates a degree of undertapping. To choose the appropriate tap size, reference the Tap Dimension Table for values to determine the amount of undertapping.

Note: 6 mm taps are offered in two lengths to provide the surgeon the option to choose a suitable instru-ment based upon the vertebral level and patient size.

For diameter 8 mm screws and larger, it is recommended to apply a sequential tapping procedure. Start with a smaller tap diameter and complete sequentially tapping steps, increasing tap diameter until the desired screw diameter is reached. It is recommended to limit the change in hole diameter by one size and to tap to the full length of the screw intended to be placed.

Note: In order to decrease the amount of torque re quired for large diameter screws, the degree of undertapping is reduced for 8 mm taps and larger. Reference the EXPEDIUM 5.5 System Tap Dimension Table for values.

To connect the tap to the Quick Coupling, push the outer ring away from the powered handpiece and insert the tap until the hexagonal flange is flush with the Quick Coupling. Verify that the tap is retained by gently pulling on it.

The handpiece has a proportional trigger control, meaning that the further the trigger is depressed, the faster the tap will be rotated.

Make sure the mode selector switch of the powered handpiece is in the ON position.

Apply the instrument to the entry point of the cannu-lation and depress lower trigger until tapped to desired depth.
