Abstract

An endoscopic apparatus for harvesting a desired blood vessel including an endoscopic barrel having at least two lumens, one of the lumens dimensioned for receiving an endoscope, a handle disposed at a proximal end of the endoscopic barrel, a cone portion disposed over a distal end of the endoscopic barrel, and at least one manipulator fork extendable from the cone portion for dissecting the desired blood vessel from connective tissue.

Claims

1. An endoscopic apparatus for harvesting a desired blood vessel comprising:

an endoscopic barrel including at least two lumens, one of said lumens dimensioned for receiving an endoscope;

a handle disposed at a proximal end of the endoscopic barrel;

a cone portion disposed over a distal end of said endoscopic barrel; and

at least one manipulator fork extendable from said cone portion for dissecting the desired blood vessel.

2. The endoscopic apparatus of claim 1, wherein said cone portion includes at least one recess for receiving said at least one manipulator fork in a retracted position such that a contoured profile of said portion is maintained.

3. The endoscopic apparatus of claim 2, wherein said endoscopic barrel includes at least three lumens and said apparatus further comprises a cutting device extendable from said cone portion for cauterizing and ligating the desired blood vessel.

4. The endoscopic apparatus of claim 3, wherein said cone portion further includes a recess for receiving said cutting device in a retracted position such that a contoured profile of said portion is maintained.

5. The endoscopic apparatus of claim 1, wherein said at least one manipulator fork includes a control assembly permitting rotational and translational movement of said at least one manipulator fork.

6. The endoscopic apparatus of claim 5, wherein said at least one manipulator fork comprises a form arm and a distal fork.

7. The endoscopic apparatus of claim 6, wherein said control assembly comprises a rotatable control mechanism slidable within a predefined track on said handle.

9. The endoscopic apparatus of claim 6, wherein said control assembly further permits swivelling of said distal fork relative to said fork arm.

10. The endoscopic apparatus of claim 9, wherein said at least one manipulator fork further comprises fork swivel control tube disposed over said form arm.

11. The endoscopic apparatus of claim 10, wherein said control assembly further includes a swivel control ring disposed on said handle.

12. The endoscopic apparatus of claim 1, wherein said endoscopic barrel includes at least three lumens and said at least one manipulator fork comprises two manipulator forks.
