Instructional Guide for NeoGrip Surgical Instrument
The NeoGrip surgical instrument was designed to work with the surgeon’s hand for improved
grip, balance and efficient maneuvering within the surgical site. This instructional guide
illustrates the different grips that can be used when working with the NeoGrip surgical
instrument as well as how to lock and unlock. The NeoGrip handle works ergonomically
with the surgeon’s hand and wrist to reduce muscle fatigue and cramps.

Palm Grip
A standard palm grip can be used by placing the
NeoGrip handle into the palm of the hand. This grip
allows for maneuvering of the surgical instrument at
flat angles to the wrist. As the image to the left
demonstrates, the handle of the surgical instrument is
placed into the palm of the surgeon’s hand.
The 4th and 5th digits are wrapped around the handle
to provide stability. The other handle is placed against
the base of the thumb for opening and closing the
instrument.
The handle is pressed against the base of the thumb
for opening and closing.

4th and 5th digits are wrapped around the handle for
stability.
Base of the thumb is used to open and close
the surgical instrument.
When opening the instrument, the base of the thumb
is used to maneuver the instrument open and closed
as illustrated in the image on the right. The tip of the
thumb can be used as well to open and close the
surgical instrument if that is preferred.
The index finger can be extended along the shanks
for maneuvering if preferred.

4th and 5th digits hold the handle for stability.

Locking and Unlocking with a Palm Grip
To lock the NeoGrip instrument, the base of the thumb
presses firmly against the handle which pushes the
two shanks together until the instrument is locked.
The 4th and 5th digits are used to stabilize the other
handle as the instrument locks in place. The instrument
is locked in the image on the left.

The base of the thumb is used to press firmly against
the handle.
4th and 5th digits hold the instrument stable.

Base of the thumb pushes down firmly to unlock.
When unlocking the instrument using a palm grip, the
base of the thumb presses firmly against the end of
the handle until the locking mechanism releases.
The 4th and 5th digits hold the other handle firmly
to keep the instrument from rotating. The tip of the
thumb can be used as well to push down on the
shank which will also release the locking mechanism.

4th and 5th digit hold the handle firmly to keep the
instrument from rotating.

The thumb can then be used to open and close the
instrument for continued use.

Modified Palm Grip
One of the advantages of the NeoGrip instrument
is the ability to change grips quickly and efficiently.
With this modified palm grip the 3rd and 4th digits
are holding the handle in place while the base of the
thumb (or tip if preferred) is used to open and close
the instrument.

Base of thumb is used to open and close
the instrument.

3rd and 4th digits hold the handle in place to stabilize
the instrument.

Base of thumb is used to open and close
the instrument.
Another modified palm grip is to use the 2nd and 3rd
digits to hold the handle in place while the base of
the thumb (or tip if preferred) is used to open and
close the instrument.
With these modified palm grips it is up to the surgeon
to decide what grip feels and works best for them.

The 2nd and 3rd digits are used to hold the handle
stable.

Pencil Grip
A pencil grip is the most precise grip the human hand can use. Because of our years of training to use writing
implements, the human hand can maneuver using the pencil grip with great efficiency and agility. The design
of the NeoGrip surgical instrument is based on the pencil grip to give the surgeon the ability to use instruments
that require precise movements while at the same time maintaining an ergonomic angle of the wrist and hand
to the surgical site.

As seen in the image to the left, when using a
pencil grip, the wrist and hand are at ergonomic
angles to the surgical site. This reduces muscle
fatigue and cramping during the surgical procedure.
Because the rings have been removed the instrument
now fits precisely in the surgeon’s hand for easy
maneuverability.

The wrist is flat and relaxed.
Instrument is facing the surgical site.

The handle is placed at the base of the thumb and
2nd digit.
A closer look at how to use the pencil grip is demonstrated in the image on the right. The handle to the
right is placed between the base of the thumb and
2nd digit. The 3rd digit is placed in the groove at the
base of the right handle to hold the handle against
the base of the thumb and 2nd digit. The tip of the
thumb and 2nd digit are on opposite sides of the
handle on the left. They will be used for opening and
closing the instrument.

The tip of the thumb and 2nd digit are on opposite
sides of the handle for maneuvering.

The 3rd digit is placed in the groove at the base of the
handle to hold the handle in place.

The 4th digit helps brace
and stabilize the right shank.

5

To open and close the instrument, the handle on the
left is extended or retracted using the tip of the thumb
and 2nd digit. The 3rd digit stabilizes the right handle
by holding it firmly against the base of the thumb and
2nd finger. The 4th digit can be used to brace and
stabilize the right shank for efficient maneuvering.

The 3rd digit holds the handle firmly against the base
of the thumb and 2nd digit for stability.

The tips of the thumb and 2nd digit open and close
the instrument.

Locking and Unlocking with a Pencil Grip

When locking the instrument, the tip of the thumb
and 2nd digit force the two handles together until the
instrument locks. The third digit is used to stabilize the
instrument at the base of the thumb and 2nd digit.
The 4th digit can be used to brace the instrument as
well. In the image on the left the instrument has been
locked.

The 3rd and 4th digits are used to stabilize the
instrument.

The tip of the thumb and 2nd digit force the two
handles together for locking.

6

To unlock the instrument, the thumb is slid over to
the handle on the right and used to hold the handle
between the 3rd digit and thumb. Holding the handle
between the 3rd digit and thumb stabilizes the instrument and prevents it from rotating. The 4th digit is also
used to brace the right shank and stabilize the instrument. The 2nd digit applies a oblique force to the opposite handle toward the thumb once the instrument
is stabilized. The locking mechanism will then release.

2nd digit applies an oblique force toward the thumb.

The thumb and 3rd digit hold
the right handle for stability.

The 4th digit braces the right shank for stability.

Once the instrument is unlocked, the thumb can be
slid back to the left handle for opening and closing as
previously discussed.

The 3rd digit holds the handle firmly against the base
of the thumb and 2nd digit for stability.

Modified Pencil Grip
With a modified pencil grip, the tip of the thumb and
2nd digit manipulate the handle on the left as with
the standard pencil grip, but the handle on the right is
firmly under the base of the 2nd digit. The 3rd and 4th
digits hold the shank on the right in place as the
instrument is maneuvered around the surgical site.

The handle is placed firmly against the base
of the 2nd digit.

The 3rd and 4th digit hold the right shank between
them for stability.

manipulate the left handle.

The handle is placed firmly against
the base of the 2nd digit.
In viewing the modified pencil grip from below, the
image on the right shows the handle firmly under the
base of the 2nd digit with the 3rd and 4th digits holding the right shank for stability. The tips of the thumb
and 2nd digit manipulate the left handle for opening
and closing the instrument.

The tip of the thumb and 2nd
digit manipulate the left handle.

The 3rd and 4th digits hold the
right shank between them for stability.

8

The tip of the thumb and 2nd digit are used to open
and close the instrument as well as maneuver within
the surgical site as was demonstrated with the
standard pencil grip.
Locking and unlocking using the modified pencil grip
is the same as with the standard pencil grip.
The thumb is slid to the right handle for stability and
the 2nd digit uses an oblique force on the opposite
handle toward the thumb to unlock the instrument.
The right handle is held firmly against the base of the
2nd digit for stability.

The 3rd and 4th digits
stabilize the right shank.
The tip of the thumb and 2nd digit manipulate the
instrument open and closed.
When using the NeoGrip surgical instrument in the left hand, all of the grips discussed in this guide
can still be used. The only difference is the locking and unlocking of the instrument.
To unlock the instrument, the 4th and 5th digits are used to press firmly against the handle.
The locking mechanism will release and all other maneuvering is the same.
The thumb and 2nd digit are used to stabilize the instrument as discussed previously.
