Abstract:
A surgical device for providing haptic feedback includes a housing having a cavity defined therein configured to receive a finger of a user and an elongated shaft configured to extend through the housing and into the cavity and configured to support a spring thereon and a pressure contact. A fluid-filled sensor is included that has a plurality of tubes configured to extend from the cavity, each tube includes a fluid-filled bladder at both ends thereof joined by a fluid channel therebetween. Each tube is configured to contain a fluid therein such that when a user's finger is engaged between the fluid-filled bladder at the proximal end of the tubes and the pressure contact, changes in pressure in the fluid-filled bladders at a distal end of the tubes is correspondingly registered in the fluid-filled bladders at the proximal end of the tubes providing haptic feedback to the user.
