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.
Claims23
An instrument guide device comprising:
- 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 and handle;
- a distal bendable member disposed at the distal end of the guide shaft;
- a proximal bendable member disposed at the proximal end of the guide shaft;
- and
- actuation means extending between said distal and proximal bendable members and providing a bending of said distal bendable member controlled from said proximal bendable member;
- whereby said proximal bendable member is controlled from said manually operated instrument to cause a corresponding bending of said distal bendable member.
A surgical instrument assembly comprising:
- an elongated instrument shaft having proximal and distal ends;
- a working member coupled from the distal end of the instrument shaft;
- a control handle disposed at the proximal end of the instrument shaft;
- a guide member for receiving the instrument shaft and including;
- a guide shaft;
- a distal motion means at the distal end of said guide shaft;
- a proximal motion means at the proximal end of said guide shaft;
- and
- actuation means extending between said distal and proximal motion means;
- said working member extending beyond a distal end of the guide shaft at an operative site;
- whereby any deflection of said proximal motion means causes a corresponding deflection of said distal motion means for control of said working member.
A surgical instrument comprising:
- an elongated instrument shaft having proximal and distal ends;
- a working member disposed at the distal end of the instrument shaft;
- and
- a control handle disposed at the proximal end of the instrument shaft;
- said working member being coupled to the distal end of said elongated instrument shaft via a distal motion member;
- said control handle coupled to the proximal end of said elongated instrument shaft via a proximal bendable member;
- actuation means extending between said distal and proximal members whereby any deflection of said control handle with respect to said elongated instrument shaft causes a corresponding bending of said distal motion member for control of said working member;
- wherein at least said proximal bendable member comprises a unitary slotted structure having a plurality of discs separated by slots.
