Endoscopic surgical instrument
First Claim
1. An endoscopic surgical instrument comprisingan outer member having a distal end and an opening at said distal end,a surgical implement movably disposed within said outer member at said opening, andan irrigation sheath through which said outer member extends to define a passage between said outer member and said sheath for conveying fluid from a proximal region of the surgical instrument to the distal end of the outer member,said sheath having a distal end that includes an opening configured to receive and at least partially surround said distal end of said outer member to define an outlet for the fluid adjacent to an edge of said opening of said outer member.

Abstract
An endoscopic surgical instrument is provided that includes a surgical implement, e.g., a cutting tool, and an irrigation device that supplies fluid to the surgical implement during use of the device. The endoscopic surgical instrument includes a surgical implement disposed at a distal region of the surgical instrument, and an irrigation device associated with the surgical implement in a manner to define a path for conveying irrigation fluid from a proximal region of the surgical instrument to the surgical implement.

1. An endoscopic surgical instrument comprising
an outer member having a distal end and an opening at said distal end, a surgical implement movably disposed within said outer member at said opening, and an irrigation sheath through which said outer member extends to define a passage between said outer member and said sheath for conveying fluid from a proximal region of the surgical instrument to the distal end of the outer member, said sheath having a distal end that includes an opening configured to receive and at least partially surround said distal end of said outer member to define an outlet for the fluid adjacent to an edge of said opening of said outer member.

14. A method of performing endoscopic surgery comprising:
-
(a) providing an endoscopic surgical instrument including an outer member having a distal end and an opening at said distal end, a surgical implement movably disposed within said outer member at said opening, and an irrigation sheath through which said outer member extends to define a passage between said outer member and said sheath for conveying irrigating fluid from a proximal region of the surgical instrument to the distal end of the outer member, said sheath having a distal end that includes an opening configured to receive and at least partially surround said distal end of said outer member to define an outlet for the fluid adjacent to an edge of said opening of said outer member; (b) introducing said surgical instrument into an area of the body of a patient; (c) conveying the irrigating fluid from the proximal region of the surgical instrument through the passage and out of the outlet into the area; (d) using the surgical implement to perform a surgical technique on the patient at the area. - View Dependent Claims (15, 16, 17)

18. An endoscopic surgical instrument comprising
an outer member extending from a proximal region mounted to a hub to a distal end, said outer member having an opening at said distal end, a surgical implement carried by an inner member movably disposed within said outer member, said surgical implement being disposed at said opening, and an irrigation sheath through which said outer member extends to define a passage between said outer member and said sheath for conveying fluid from a proximal region of the surgical instrument to the distal end of the outer member, said sheath having a proximal end that is removably attachable to said hub, and a distal end that includes an opening configured to receive and at least partially surround said distal end of said outer member to define an outlet for the fluid adjacent to an edge of said opening of said outer member.

19. An irrigation device for use with endoscopic surgical instrument of the kind that includes an outer member having a distal end and an opening at said distal end, and a surgical implement movably disposed within said outer member at said opening, said irrigation device comprising
an irrigation sheath configured to be attached to said surgical instrument and through which the outer member extends when the sheath is so attached to define a passage between the outer member and said sheath for conveying fluid from a proximal region of the surgical instrument to the distal end of the outer member, said sheath having a distal end that includes an opening configured to receive and at least partially surround the distal end of the outer member to define an outlet for the fluid adjacent to an edge of the opening of the outer member.
