Intended Use/Purpose
JAWS and JAWS XFS (Extra Force Spring) are heavy duty, voluntary opening (VO), body
powered, terminal devices, which operate universally as either right or left-handed.
JAWS are waterproof and are truly a "cross-over" type of prosthetic device capable
of enhancing control over tools, handles and equipment as well as very functional
for vehicle control of work and recreational vehicles such as forklifts, tractors, ATVs,
snowmobiles, motorbikes and cycles and jet ski type watercraft. JAWS are a perfect,
functional compliment to users of VO split hook technology providing a range of
performance and control not possible with that type of technology . JAWS mount easily
to any USA standard prosthetic wrist .
*JAWS XFS is only intended for users who need extremely strong gripping forces.
JAWS XFS should be used with extreme caution, especially in the highest force
position, because "releasing the grip" has an extremely high threshold. Additionally,
if operating the JAWS XFS with a traditional cable system it may cause premature
wear and possible failure of the cable system, due to the extra force required to
operate the TD.
The device is intended for single user/patient use only.
Performance Characteristics
JAWS can be operated in three ways. Cable operation, Manual "pull open" using a
built-in, "trigger" feature or Push-On/Pull-Off (Snap ON-OFF) feature. JAWS models have
no lock system for safety. JAWS have a manual, shift mechanism, providing 4 gripping
force levels. JAWS are equipped with large compliant but tough synthetic rubber
gripping surfaces for optimum control over handles and cylindrical objects. JAWS have
a manually adjusted, friction, wrist pivot system that provides the user with greater
range of motion control over objects reducing elbow and shoulder joint movement
and compensation .
