Abstract
A surgical instrument and method for using it for invaginate stripping of vericose veins from the human body utilize an elongate flexible tube provided with a pair of perforations at its distal end. The perforations provide for delivery of vasodilator fluid from within the tube to the vein lumen to dilate constricted portions of the vein and allow the inverted portion of the vein to pass therethrough. The perforations also provide for the attachment of sutures to the instrument and for the attachment of a stripper head to the instrument when necessary to retrieve a vein that tears during invaginate stripping.
Claims3
A method of using a surgical instrument for the invaginate stripping of vessels from the human body, the method comprising the steps of:

- (b) attaching sutures to the instrument to secure a ligated end of the blood vessel thereto;
- (c) providing traction to the instrument so as to invert the wall of the blood vessel and draw the inverted wall into the lumen;
- (d) supplying fluid through the instrument into the lumen of the blood vessel to dilate the lumen and permit unobstructed passage of the inverted wall therethrough.
