Abstract:
1. An instrument having a proximal control handle and a distal tool that are intercoupled by an elongated instrument shaft, proximal and distal movable members that respectively intercouple said proximal control handle and said distal tool with said instrument shaft, means disposed between said movable members so that a motion at said proximal movable member controls said distal movable member, means for restraining said distal movable member at a first relative position between said movable members, means for enabling said proximal movable member to be moved from said first relative position to a second relative position between said movable members while said distal movable member is so restrained by said means for restraining, said means for restraining being releasable to enable subsequent control of said distal movable member from said proximal movable member commencing from said second relative position, wherein said means disposed between said movable members includes cabling and said means for restraining includes a cable pinching member that holds the cabling distal thereof immobile, and wherein said means for enabling includes a follower having locked and unlocked states, said follower spacedly disposed proximal to said proximal movable member, and said follower being in its unlocked state to enable said proximal movable member to be moved from said first relative position to said second relative position.
