Abstract
An instrument system comprising a flexible shaft having proximal and distal portions, a backend mechanism coupled to the proximal portion, and a plurality of tendons including first and second tendons. The backend mechanism comprises a plurality of capstans including first and second capstans. Each capstan includes a bore for engagement with a drive shaft, and a capstan coupling member adapted to engage a drive shaft coupling member such that rotation of the drive shaft causes rotation of the capstan, and adapted to disengage from the drive shaft coupling member so rotation of the drive shaft does not cause rotation of the capstan. The first tendon is configured to wrap around the first capstan and the second tendon is configured to wrap around the second capstan. The first and second tendons are coupled to a member disposed at the distal portion and are configured to move the member in opposing directions.
