Section 3  BATTERY INSTALLATION
CLASSIC PLUS
3.1 BATTERY INSTALLATION
Internal Batteries from Other Manufacturers
Other manufacturer batteries must be used to power the hand and
wrist. These are typically 7.4V nominal battery packs with accompanying
charging port/power button, and charger. Batteries may be installed
above or below the elbow and must be in conformance with all applicable
safety and operational specifications.
Above Elbow Battery Location
Batteries that are mounted above the elbow can be connected to the
top of the input board using the input wire supplied by the battery
manufacturer (see section 2). A pre-installed pathway routes battery
power from above the elbow to the distal end of the forearm
(see section 4.2).
Below Elbow Battery Location
The Espire Classic Plus provides a compartment on the bottom side
of the elbow for housing other manufacturers’ batteries. Batteries can
be installed in this compartment, providing the battery dimensions fit
without modifying the arm.
1. Route the battery wire through the hole inside of the compartment into the
forearm.
2. Substitute the pre-installed power output wire for one supplied by the battery
manufacturer, then route the wire through the forearm.

Wiring
The hand-open, hand-close, and power output cables will plug into a
single coaxial unit which fits through the center of the quick disconnect
wrist.
1. Plug the orange (hand-open) cable into
the left plug labeled “2”, then plug the
green (hand-close) cable into the right
plug labeled “2”.
2. Plug the red (power) output cable into the
plug labeled “1”.
Note: If the two 3-socket connectors (hand-open/hand-close) are
attached to the wrong plugs labeled “2”, the open-close functions will
operate in reverse.
5.4 ELECTRONIC WRIST ROTATORS
CLASSIC PLUS
Electronic wrist rotators require a battery that supplies an additional plug
for the wrist power (See section 3.1). To connect a wrist rotator, install
the battery in the forearm and use that unique system. The wire should
be attached to the battery, run though the distal end of the forearm,
and connected to the wrist. Contact the wrist manufacturer for more
information.

SECTION 6  THE LAMINATION
COLLAR AND CLAMP RING
6.1 ORIENTATION OF THE LAMINATION
COLLAR AND CLAMP RING
The lamination collar must be oriented properly relative to the patient
socket to allow for correct internal / external humeral rotation and to
protect the wiring of the Espire Elbow.
Line indicates posterior
Anti-rotation pin
located internally on
the underside of the
lamination collar
Colors for representation only.
The clamp ring is a two-piece assembly that is uniquely shaped to fit the
profile of the Espire Elbow. When assembled to the elbow, the clamp
screws will face posterior.
6.2 INTERNALEXTERNAL ROTATION
The Espire is designed with a humeral rotation stop pin to prevent
360-degree rotation. This feature is to prevent input wires from being
twisted and potentially damaged. The stop pin allows for 100° external /
100° internal rotation for a total range of 200°.
Info: Normal human range of motion is 30° externally and
135° internally.

6.3 ATTACHING THE LAMINATION COLLAR
TO THE ELBOW
1. Disassemble the clamp ring by removing
the fasteners.
2. Place the lamination collar (or socket with
attached collar) near top of the elbow.
3. Plug appropriate cables into the input
board (if applicable, see section 2.3).
4. Insert Clamp Ring A around both the
anterior end of the lamination collar and
elbow attachment.
5. Then insert Clamp Ring B around both the
posterior end of the lamination collar and
elbow attachment.
6. Insert the fasteners and torque slightly,
enough to fasten the clamp ring together.
Apply equal torque to both fasteners.
6.4 DETERMINING PROPER ORIENTATION
ON TEST SOCKET
The lamination collar attachment to the socket must provide a clinically
acceptable measurement from center axis of shoulder to center axis
of elbow. The appropriate elbow carry angle must also be established,
preferably for full extension.
1. Test the collar orientation by placing it under the user’s test socket with the
orientation line facing posterior. It may be necessary to extend the collar away
from the socket to establish the correct elbow position. Mark where the collar
contacts the socket or extension material.
2. Remove the clamp ring from the lamination collar and elbow.
3. Temporarily attach the collar to test socket using fiberglass tape, epoxy
or other adhesive. Clean any residue from the collar surface at the elbow
attachment point.
4. Re-attach the elbow to the lamination collar and test socket. Rotate the
forearm clockwise and counterclockwise and verify the stop positions at 100
degrees from center (see section 6.2). Rotate the collar accordingly to adjust
the amount of internal or external rotation.
5. Temporarily fit the arm to the user, verify that the position, carry angle, and
elbow center are appropriate. Record the data.
6. Create a new mold for the definitive socket. Transfer the measurements and
position from the test socket.
7. Fabricate the definitive socket with sensors and applicable prosthetic
materials.
Info: For more information on lamination, see Espire Elbow Fabrication
Instructions.

13 | Espire Elbow Technical Manual
6.5 FINAL ADJUSTMENT WITH THE USER
The humeral rotation is adjusted with a 2.5mm hex key that is supplied
with the clamp ring. While the user is wearing the prosthesis, adjust
the friction until it is most comfortable. This friction can be adjusted as
needed.
Note: Overtightening this screw may damage the screw threads. Use
small, controlled adjustments until the desired amount of friction is
reached.

or unlocked while under load, with a maximum support of 25 lbs.
The manual lock cable is attached to the upper elbow assembly, near
the midline. The lock can be engaged/disengaged every 10 degrees (13
positions). A strain-relief is included to reduce the likeliness of damage
due to excessive pull on the lock cable.
The lock cable can be used with or without a harness. Attach the cable
to a harness using your preferred mounting method. The cable may be
shortened, but do not remove it completely.
Caution: Complete removal of the manual lock cable can lead to
malfunction and injury to the user.
Note: The manual lock is not removable or field-serviceable. Do not
attempt to disassemble or modify the unit.
