Abstract

Certain embodiments are directed to mechanical devices for augmenting dexterous reach and sensing of a user. The devices can include a proximal portion configured to receive an appendage of a user; a distal portion configured to detect sensory information; an articulation positioned between the proximal and distal portion to provide for motion of the distal portion via manipulation of the proximal portion; wherein the distal portion comprising a sensing element and the proximal portion comprises a feedback element, the feedback element being connected to the sensing element providing for physical extension of sensory capabilities of the appendage.

First claim

The invention claimed is:

1. A medical device configured for extending dexterous reach and sensing of a finger comprising:
a proximal attachment portion in the form of a hand mount, glove, wrist strap, or sleeve configured to receive and attach to a wrist or hand of a user;
a distal portion comprising a distal sensor, the distal portion having a maximum diameter of 0.01 to 5 cm; and
a digital extender portion having an extended length of 1 to 24 inches and a diameter of 0.01 to 5 cm that is configured to receive a finger of the user, the digital extender portion comprising a feedback element and at least one articulation, the digital extender portion is positioned between the distal portion and the proximal portion;
wherein the feedback element is connected to or in communication with the sensor, the feedback element is configured to be connected to or in communication with the user's fingertip during use providing physical extension of sensory capabilities of the user's fingertip.

2. The device of claim 1 , wherein the sensor is a thermal, capacitive, pneumatic, hydraulic, resistive, vibrational, and/or piezoelectric sensor, wherein sensory information is haptically communicated to the user's natural receptors when in use.

3. The device of claim 1 , wherein the device is configured to translate movement of the user's finger to movement of the distal portion.

4. The device of claim 3 , wherein the translation of movement is scaled at a scale of 1000:1 to 1:1 to 1:1000 proximal distance moved to distal distance moved.

5. The device of claim 1 , wherein the device is made of materials that are capable of being sterilized.

6. The device of claim 1 , wherein the device comprises 1, 2, 3, or 4 independent digital extender portions.

7. The device of claim 1 , wherein the device comprises one digital extender portion.

8. The device of claim 1 , wherein the device comprises 2 digital extender portions.

9. The device of claim 1 , wherein the length of the digital extender portion is adjustable.

10. The device of claim 1 , wherein the digital extender portion comprises at least two articulations.

11. The device of claim 1 , further comprising a steering mechanism.
