Abstract

An endoscopic instrument has a control member (220), a portion of the member having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the control member by providing peripheral projections (232) of fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross-sectional area between the interior of the endoscope instrument shaft and the central control member. The resulting instrument has significantly reduced backlash in end effector (228) assembly manipulation, while maintaining adequate fluid flow in the endoscope shaft.

Claims (24)

1. An endoscopic instrument system, comprising:
an endoscope having an elongate flexible distal portion and a proximal handle portion for manipulating said distal portion including an optics channel which receives an imaging means and a working channel having an interior surface and adapted to receive an endoscopic instrument therethrough; and an endoscopic instrument including an outer elongate flexible tubular member having proximal and distal ends and an outer surface, a control member having proximal and distal ends, said control member extending through said tubular member, an end effector assembly coupled at least to the distal end of the control member, and a first handle means for moving said control member relative to said tubular member to operate said end effector assembly coupled to the proximal end of the control member;
wherein at least one of said inner surface of said tubular shaft member and said outer surface of said control member is provided with a non-circular cross-sectional shape along a portion thereof adapted to reduce backlash when moving said control member relative to said tubular member of said endoscopic instrument.
2. The endoscopic instrument of claim 1, wherein the control member further comprises an interior surface defining a lumen therethrough.
3. The endoscopic instrument of claim 1, wherein the end effector assembly comprises a needle.
4. The endoscopic instrument of claim 1, wherein the control member handle means further comprises:
an internal wall defining a lumen therethrough; and a fitting adapted for attachment to a fluid source, attached to the proximal end of the first handle means.
5. The endoscopic instrument system of claim 3, further comprising a tubular shaft handle means connected to the proximal end of the outer elongate flexible tubular shaft member.
6. The endoscopic instrument system of claim 4, wherein the tubular shaft handle means further comprises a fitting adapted for attachment to a fluid source.
7. An endoscopic instrument system according to claim 1, wherein said non-circular cross-sectional shape is a polygonal shape.
8. An endoscopic instrument system according to claim 1, wherein said non-circular cross-sectional shape includes a plurality of radial projections.
9. An endoscopic instrument system according to claim 1, wherein said portion is a portion along said control member on which a jacket is provided which includes a plurality of fins over said control member.
10. An endoscopic instrument according to claim 10, wherein said fins are radially spaced and directed radially outward.
11. An endoscopic instrument according to claim 10, wherein said fins are approximately 0.2 mm thick.
12. An endoscopic instrument according to claim 10, wherein said fins extend outward approximately 0.2 mm from a surface of said control member.
13. An endoscopic instrument system according to claim 1, wherein said portion is a portion of said endoscope shaft of said endoscope instrument, and said portion includes a plurality of substantially radially inwardly directed ribs.
14. An endoscopic instrument system according to claim 1, wherein said portion is a portion of said endoscope shaft which is provided with an insert having said non-circular cross-sectional shape.
15. An endoscopic instrument system according to claim 1, wherein said proximal end of said control member is substantially circular in cross-sectional shape.
16. An endoscopic instrument for insertion through an endoscope having a working channel, said endoscopic instrument comprising:
an elongate flexible tubular shaft member having proximal and distal ends and an outer surface, said outer surface having a portion having a non-circular cross-sectional shape;
a control member having proximal and distal ends and extending through said tubular member;
wherein at least one of said inner surface of said tubular shaft member and said outer surface of said control member is provided with a non-circular cross-sectional shape along a portion thereof adapted to reduce backlash when moving said endoscopic instrument relative to said working channel of said endoscope;
an end effector assembly coupled to at least one of said distal ends of said tubular member and said control member; and means for moving said control member relative to said tubular member to operate said end effector assembly.
17. An endoscopic instrument according to claim 16, wherein said portion of said outer surface of said control member or said inner surface of said tubular shaft member provided with said non-circular cross-sectional shape has a non-circular cross-sectional shape which makes the smallest radius of said inner surface of said tubular shaft member nearly equal to the largest radius of said outer surface of said control member, such that when said control member is moved longitudinally relative to the endoscopic instrument tubular shaft member, backlash is reduced.
18. An endoscopic instrument according to claim 16, wherein said non-circular cross-sectional shape is defined by a jacket provided over said tubular member, said jacket including a plurality-of longitudinal fins.
19. An endoscopic instrument according to claim 16, wherein said non-circular cross-sectional shape is defined by a plurality of longitudinal fins extending radially outward from said tubular member.
20. An endoscopic instrument according to claim 16, wherein said non-circular cross-sectional shape is defined by a jacket provided over said tubular shaft member, said jacket having a substantially polygonal shape.
21. An endoscopic instrument according to claim 16, wherein said non-circular cross-sectional shape is defined by a jacket provided over said control member, said jacket having a substantially polygonal shape.
22. An endoscopic instrument according to claim 16, wherein said portion of said outer surface of said control member which has said non-circular cross-sectional shape is defined by a low friction jacket provided over said portion, said low friction jacket having said non-circular cross-sectional shape.
23. An endoscopic instrument according to claim 16, wherein said proximal end of said tubular member is substantially circular in cross-sectional shape.
24. An endoscopic instrument according to claim 16, wherein said tubular member is a coil.
