1. A surgical device, comprising:

  • a) a tubular member having proximal and distal ends;

    b) a first control element wire extending through said tubular member and having proximal and distal ends;

    c) at least one second control element extending through said tubular member and having proximal and distal ends; and

    d) a handle comprising (i) a stationary member, (ii) a first lever coupled to said proximal end of said at least one second control element and linearly movable relative to said stationary member to effect relative proximal and distal movement of said at least one second control element relative to said tubular member, said first lever being lockable and unlockable in position relative to said stationary member, (iii) a rack member linearly movable within said handle and fixedly coupled to said proximal end of said first control element, (iv) a second lever rotatably coupled to said first lever, (v) a pinion rotatable coupled to the second lever, and (vi) a spring element biasing said pinion against said rack member, such that when said second lever is rotated relative to said first lever, said pinion effects substantially linear movement of said rack member and thereby causes proximal and distal movement of first control element relative to said tubular member.
