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.

Claims

1. 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.

2. The instrument guide device of claim 1 wherein said actuation means is constructed and arranged so that a bending of the proximal bendable member causes a like direction bending of the distal bendable member.

3. The instrument guide device of claim 1 wherein said actuation means is constructed and arranged so that a bending of the proximal bendable member causes an opposite direction bending of the distal bendable member.

4. The instrument guide device of claim 1 wherein said proximal bendable member is moveable in any direction.

5. The instrument guide device of claim 1 including a grip disposed between said proximal bendable member and the handle of said instrument and constructed and arranged to have a passage through which the instrument shaft extends.

6. The instrument guide device of claim 5 wherein said grip is formed as two pieces including a grip portion and a rotation knob and said grip and knob portions are supported for relative rotation therebetween.

7. The instrument guide device of claim 5 including means or securing the instrument handle to the grip.

8. The instrument guide device of claim 1 wherein said bendable members each comprise a unitary slotted structure having a plurality of discs separated by slots.

9. The instrument guide device of claim 1 wherein said guide shaft is rigid.

10. The instrument guide device of claim 1 wherein said guide shaft is flexible.

11. The instrument guide device of claim 1 including a plurality of proximal bendable members and a plurality of distal bendable members.

12. The instrument guide device of claim 1 wherein said actuation means comprises a plurality of cables that interconnect proximal and distal bendable members.

13. The instrument guide device of claim 1 wherein said guide shaft has at least two lumens for respectively accommodating separate instrument shafts.

14. The instrument guide device of claim 1 wherein said instrument has instrument proximal and distal bendable members.

15. 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.

16. The surgical instrument assembly of claim 15 wherein said distal motion means comprises a distal bendable member and said proximal motion means comprises a proximal bendable member that is moveable in any direction.

17. The instrument guide device of claim 16 including a grip disposed between said proximal bendable member and the handle of said instrument and constructed and arranged to have a passage through which the instrument shaft extends.

18. The instrument guide device of claim 17 wherein said grip is formed as two pieces including a grip portion and a rotation knob and said grip and knob portions are supported for relative rotation therebetween.

19. The instrument guide device of claim 16 wherein said proximal bendable member comprises a unitary slotted structure having a plurality of discs separated by slots and further including a plurality of ribs interconnecting adjacent discs, said ribs being disposed at intervals about the member of less than 90 degrees.

22. The instrument guide device of claim 16 wherein said proximal bendable member includes a plurality of ribs interconnecting adjacent discs, said ribs being disposed at intervals about the member of less than 90 degrees.

23. The instrument guide device of claim 22 wherein said ribs are disposed at an interval on the order of 60 degrees.

20. 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.

21. The instrument guide device of claim 20 wherein said distal motion member also comprises a bendable member formed as a unitary slotted structure having a plurality of discs separated by slots.
