1. A surgical instrument assembly comprising:
- an elongated instrument shaft having proximal and distal ends;
an end effector coupled from the distal end of the instrument shaft;
a control handle disposed at the proximal end of the instrument shaft;
said elongated instrument shaft, end effector and control handle defining a manually operated instrument having inserted and withdrawn positions;
a guide member for receiving the manually operated instrument and including;
a guide shaft having respective proximal and distal ends;
a distal bendable member at the distal end of said guide shaft and having at least a distal end;
a proximal bendable member at the proximal end of said guide shaft and having a proximal end and a distal end;
an adaptor coupled between the distal end of the proximal bendable member and the proximal end of the guide shaft;
said adaptor receiving and supporting the distal end of the proximal bendable member;
a grip, separate from the manually operated instrument, receiving and supporting the proximal end of the proximal bendable member;
a lumen through which the manually operated instrument is inserted distally through at least the grip, proximal bendable member, guide shaft and distal bendable member;
said lumen terminating at a distal port at the distal end of the distal bendable member and at a proximal port at the grip; and
actuation cabling extending between said distal and proximal bendable members;
said end effector extending from the distal port of the lumen at an operative site and the control handle extending from the proximal port of the lumen when the manually operated instrument is inserted through the lumen;
whereby any deflection of said proximal bendable member caused by manipulation of said manually operated instrument causes a corresponding deflection of said distal bendable member for control of said distal bendable member, and in turn, said end effector.

Abstract
An instrument guide device comprises an elongated guide shaft having proximal and distal ends and including an instrument lumen for receiving therethrough a manually operated instrument having an instrument shaft. A distal bendable member is disposed at the distal end of the guide shaft and a proximal bendable member is disposed at the proximal end of the guide shaft. Actuation means extends between the distal and proximal bendable members and provides a bending of the distal bendable member controlled from the proximal bendable member. The proximal bendable member is controlled from the manually operated instrument to cause a corresponding bending of said distal bendable member.

27. A manually controlled medical instrument that is operable in combination with a guide member by virtue of the insertion of the manually controlled medical instrument through a continuous lumen of the guide member that extends between open ports at opposite ends of the guide member,
the manually controlled medical instrument including an instrument shaft that interconnects between a manual instrument control handle and a manual instrument tool, the manually controlled medical instrument also including a an actuation member operable from the manual instrument control handle for operating the manual instrument tool, the guide member including an elongated guide shaft having proximal and distal ends, a distal bendable member disposed at the distal end of the guide shaft, a proximal bendable member having a proximal end and a distal end that is coupled with the proximal end of the guide shaft, and cabling extending between the distal and proximal bendable members and providing a bending of the distal bendable member controlled from and responsive to the bending of the proximal bendable member, a grip, separate from the manually controlled medical instrument, receiving and supporting the proximal end of the proximal bendable member, the continuous lumen also extending through the grip for accommodation of the manually controlled medical instrument shaft, the manually controlled medical instrument constructed and arranged for insertion through the lumen of the guide member and grip so as to dispose the manual instrument control handle extending proximally of the proximal bendable member of the guide member and the manual instrument tool extending distally of the distal bendable member of the guide member; -
and a fastening member for securing the manually controlled medical instrument to the grip so that there is no linear motion of the manually controlled medical instrument relative to the guide member, once secured, said manually controlled medical instrument, once inserted into the guide member, by deflection thereof controlling a bending at the proximal bendable member of the guide member that is, in turn, transferred to the distal bendable member to, in turn, control the positioning of the distally extending manual instrument tool. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
