Abstract:
1. A surgical device for removing veins from the body of a patient comprising: a handle suitable for being gripped, a hollow, elongated shaft attached to said handle, having proximal and distal ends and defining an axis generally parallel to the length of said elongated shaft, a cutting tip in the form of an annular wall that tapers outwardly in a direction away from said axis located at said distal end, said cutting tip having a generally annular blade with a diameter greater than the diameter of a vein to be removed, said annular blade having serrations on said outwardly tapered annular wall to facilitate capture and severace of side branches of the vein and a cutting edge most remote from said handle generally facing a direction away from said handle for encircling and severing the vein to be removed from surrounding tissue by advancing the device with the vein received and passing through said annular blade, and an inner cutting device comprises a longitudinal member, having a proximal end and a distal end, and a length approximately comparable to that of said shaft, and a width which allows unhindered insertion through the interior hollow portion of said shaft, and a cutting blade located at said distal end of said longitudinal member, such that said cutting blade may be protruded from said distal end of said hollow shaft of said device, by longitudinal insertion of said cutting device through said shaft toward said distal end of said shaft wherein said cutting blade comprises a pointed tip and two or more sharp edges extending towards said proximal end of said inner cutting device.
