Abstract
A torque-transmitting, variably-flexible, locking insertion device includes a hollow body having a proximal end with an entrance for receiving an instrument, a distal end with a tip for protrusion of the instrument, and a handle to be gripped by an operator. A device locks the handle to and unlocks the handle from the instrument, which is at least partly disposed within the hollow body. A device transitions the hollow body between a relatively flexible condition and a relatively stiff condition. A method for operating a torque-transmitting, locking insertion device includes placing the instrument at least partly within the hollow body and locking the handle to and unlocking the handle from the instrument. The hollow body is transitioned between a relatively flexible condition and a relatively stiff condition.
