Introduction to the Point Thumb
1
The Point Thumb is a passive (i.e. not powered) mechanical thumb for people
with thumb amputations. It features a ratcheting mechanism that enables one-
handed use and 11 distinct locking positions. The Point Thumb features integrated
compliant touchscreen compatible* ngertip pads for enhanced grip. The Point
Thumb is made from titanium for ample strength.
The Point Thumb can be exed and locked by applying a force to the dorsal side of
the ngertip. This force can be applied by the contralateral limb or by an opposing
surface (e.g., leg, table, desk, wall, chair, etc.).
*Touchscreen compatibility is not guaranteed, but has been tested on common iOS, Android, and Windows devices using standard socket
material (silicone inner liner with carbon ber outer shell)

1. depressing the push button, or
2. fully exing the nger to engage the auto spring-back feature.

kit, which includes a mounting bracket, lamination spacer, alignment tool, alignment
transfer post and mounting screws.
