1.0 i-limb select
1.1 Product Description
The i-limb select is an externally powered, multi-articulating
prosthetic hand which oers a range of features beyond the
functions of the traditional prosthetic hand.
Individually motorized digits and the unique biosim and my i-limb
app used to control the i-limb select result in one of the most
versatile prosthetic hand currently available to the global market.
Users can choose from a wide selection of automated grips and
gestures to help complete daily tasks. Grips and gestures can
then be customized further for precise control.
The i-limb select oers compliant grip through individually
powered digits with stall out ability. A manually rotating thumb
in conjunction with a pulsing, enhanced grip (vari-grip), and the
wide range of automated grip patterns lead to broad functionality.
1.2 Intended Use
The i-limb select is intended to be used by patients with upper
limb loss or deciency
1.3 Prosthesis Overview
The i-limb select is available in small or medium sizes. The hand
serial number is positioned proximal to the base of the thumb on
the connection plate. The serial number will start with a “Q” and
be followed by four numbers.

1.4 Features Catalogue
The i-limb select has 12 dierent grip options available. These grips can be accessed through biosim and the my i-limb app. This
following Features Catalogue will review the various available grips and provide a functional description of each.
Precision Pinch Grip Options
Precision pinch grip options are best for picking up small items between and the thumb and index nger. There are 4 options
available depending on how you want the other digits to perform while doing the pinch. The most popular is Thumb Precision Pinch
Closed.
Standard Precision Pinch Opened
middle, ring and little nger remain fully
opened and switch o. Index nger and
thumb provide grip.
Thumb Precision Pinch Opened
middle, ring and little nger remain
fully opened and switch o. Thumb
automatically moves to a partially closed
position. Index nger will move to provide
grip against a xed thumb.
Standard Precision Pinch Closed
middle, ring and little nger automatically
close and switch o. Index nger and
thumb provide grip.
Thumb Precision Pinch Closed
middle, ring and little nger automatically
close and switch o. Thumb automatically
moves to a partially closed position. Index
nger will move to provide grip against a
xed thumb.
Tripod Grip Options
Tripod Grip Options provide a grip where the thumb is meeting up with the index and middle digits. Typically the thumb is rotated
between the index and middle to provide more stability when gripping slightly larger objects than those with the precision pinch
grips. As a result of having a motor in each digit and the hand conforming to the shape of the object being held, the hand will
automatically form a tripod grip when the object is small enough to only be gripped between the thumb, index, and middle digits.
The advantage of using the tripod grip options is if you want the ring and small digits to stay either fully open or fully closed when
gripping.
Standard 3 Jaw Chuck (Tripod) Opened
ring and little nger remain fully opened and
switch o. Thumb, index and middle ngers
move to provide grip.
Standard 3 Jaw Chuck (Tripod) Closed
ring and little nger move to terminal
close. Thumb, index and middle ngers
move to provide grip.
Thumb 3 Jaw Chuck (Tripod) Opened
ring and little nger remain fully opened and
switch o. Thumb automatically moves to a
partially closed position. Index and middle
ngers move to provide grip against a xed
thumb.
Part number: MA 01155 Issue No. 4, January 2015
Thumb 3 Jaw Chuck (Tripod) Closed
ring and little nger move to terminal
close. Thumb automatically moves to a
partially closed position. Index and middle
ngers move to provide grip against a
xed thumb.

Additional Grip and Gesture Options
With these additional grip patterns and gestures, consider how often you perform dierent tasks and if having a program for that
activity would make it easier/faster for you to perform. Since each digit has its own motor, you can put pressure against any digit to
stop it from moving (called stalling the digit). Many of these additional grips can be performed by stalling one or more digits. If it is a
task that is not performed often (maybe using index point to press the “Shift” key on a keyboard) then you may prefer to just stall the
digit. However, if you frequently perform the task or want to go into the position without needing to put the hand against the table
or your other hand, then programming the grip may be the better option.
Thumb Park Continuous
all four ngers remain open and switch o,
only the thumb will move.
Lateral Grip
all four ngers fully close and switch o.
Only thumb will move.
Thumb Park Quick
all four ngers remain open and switch
o, for 1.5 seconds the thumb will close
and then automatically return to an open
position.
Index Point
thumb, little, ring and middle ngers close
and switch o. Only the index nger will
move.

2.0 Socket
2.1 Control Sites
The i-limb select is controlled by compact electrodes
(g. 1).
For information regarding the tting of the Touch Bionics
electrode, review the manual provided with the electrode.
Electrode Site Selection
The use of virtu-limb, the Touch Bionics’ myo-testing system,
is recommended to determine the optimal placement of
electrodes (g. 2). virtu-limb is not included with the i-limb
select. Contact Touch Bionics for information about ordering
virtu-limb.
Do not rely on previous myo-electrical
testing.
Consult Touch Bionics training materials for information on myotesting.
Figure 1. Compact Electrode
Use anatomical sites where the electrode will
maintain constant, even contact with the skin.
Avoid placing electrodes near socket interface
trim lines, bony areas, skin grafts or fatty tissue.

Prosthetist must ensure that the plastic screw provided
is utilized and properly tightened on the coaxial plug
(g.3) where the battery and electrodes connect, to
prevent loose connections .
2.2 Socket Fabrication
While fabricating the socket for the i-limb select, special
considerations will need to be given to:
1. Battery placement, size and conguration
2. Electrode position
3. Charge port placement
4. Socket length and the overall length of the prosthesis in
comparison to the opposite side.
Clinicians should have prior experience with building externally
powered prosthetic sockets before tting the i-limb select.
Touch Bionics’ batteries, charger port and switch block
components should always be used with the i-limb select.
Figure 3. Coaxial Plug
We recommend that a rubber grommet or plastic cap
is placed over any socket holes to protect the integrity
of the electrode.
During socket fabrication, appropriate measures must
be taken to prevent sweat entering into the battery
connector within the lamination ring, which may result
in a short circuit and compromise use of the device.
Conventional sweat prevention methods include the
use of drain holes and suction sealing electrodes.
Alternatively, silicone may be used to seal the interface
area between the battery connector and co-axial plug
into the prosthetic socket.
During socket maintenance, ensure a check of the
battery connector/co-axial plug interface is carried out.
Socket Material
The use of Carbon ber is not recommended due to
electrical conductivity.
Part number: MA 01155 Issue No. 4, January 2015
Coupling Piece Assembly for QWD Wrist
Insert the castelation ring (coupling piece) into lamination ring
and turn until seated. Insert retaining ring around outside edge
of coupling piece and use QWD release tool to seat the retaining ring. The QWD release tool is available to order from Touch
Bionics.
Battery Placement
Use Velcro® to position the batteries on the pre-prepared
at surfaces to prevent distortion.
Battery Placement for a Long Residual
Limb
Consideration of battery placement is particularly important
in longer sockets. The shape of the inner socket must also be
considered.
If the residual limb is long or bulbous, the position of the battery
dummies and charge port are best placed midway up the arm
along the inner socket ensuring they will not impact the ability
to don/do the prosthesis and that the postion will not result in
pressure from the residual limb that could distort the battery.
Placement of batteries should allow for removal of the inner
socket.
If the socket has a bulbous distal end, do not position batteries
or charger port around the narrow region of the prosthesis.
Part number: MA 01155 Issue No. 4, January 2015

2.3 Charge Port Placement Assembly
It is important to provide sucient space for the charge port
between the inner and outer sockets. The charge port should be
positioned so that it is unaected by forces running through the
socket to prevent damage.
Create a drill hole of 8mm through the inner surface of the
prosthetic frame. Ensure a at surface has been created to
accommodate the charge port mounting frame (if installing a
switch block as an alternative to the charger port, create a drill
hole to cater for the panel mount).
Smooth the edges of the drill hole and insert the threaded
charge port. A minimum thread height of 3.2mm above the
socket surface is required for full engagement of washers and
locking nut.
Position the M8 Lock Washer and the M8 Flat Washer before
hand tightening the the locking nut.
Use a 3/8” wrench to tighten the locking nut.
Do not overtighten.
Do not use pliers on the charge port.
Position the M8 Lock Washer and M8 Flat
Washer in place over the threaded shaft of the
charger port. Engage the M8 locking nut with
the threaded shaft and tighten rmly by hand.
The use of both the Lock Washer and Flat
Washer is vital to ensure the charge port is not
damaged by over tightening.
Do not overtighten!
Part number: MA 01155 Issue No. 4, January 2015
2.4 Battery Options

When planning battery location and dummy placement for
fabrication, keep in mind a maximum distance of 135mm is
possible between cells due to wire length.
Installing i-limb Power Pack
Utilize battery dummies on top and bottom of socket to create
necessary space to accommodate battery housing.
Use standard fabrication processes and technique to create an
opening in the socket to accommodate battery housing.
When using a switch block, it is recommended that you use the
provided Switch Template (g. 4) to guide drill holes.
Ensure there is no contact between the battery
housing and inner socket

Do not apply excessive force to the charger
socket interface during assembly.
A minimum of 2mm of free space surrounding the charger port
should be provided.
A at surface is needed to secure the charger port to the socket
interface frame. This may require additional shaping of the frame
section above the dummy battery. Use the Velcro
®
strip supplied to
attach the battery to the inside of the socket interface.

If the area between the residual limb and the lamination ring is
insucient to house the battery, you will need to position the
battery between the socket interface and the frame. This will be
necessary when:
• the residual limb is longer than 60% of the humeral or forearm
section of the prosthesis
• the battery is too large for the space available in the socket
interface frame
Cutting or modifying the battery wires in any
way will invalidate the warranty.
