Device for endoscopic vessel harvesting

Details

Inventors: Puskas, John D.;
Assignee: Emory University (Atlanta, GA)
Primary Examiner: Leubecker; John P.
Assistant Examiner:
Attorney, Agent or Firm: Jones & Askew, LLP

A endoscopic device provides improvements in the endoscopic working space by the use of a semi-tubular hood with an arched top wall and self-supporting walls that allow simultaneous manipulations of dissection, cutting, ligation, and retraction, and the like, without requiring constant application of external force; while enhancing visualization and reducing the need for cleaning the endoscopic lens.

DETAILED DESCRIPTION Applicant has devised an apparatus for removing vessels and arteries from the patient with minimally invasive procedures.
The apparatus has a self-retaining, full-length semi-tubular hood attached to a shaft that is inserted into a small incision through the skin to provide and maintain a generous work space and permits the easy insertion and use of a variety of surgical instruments simultaneously, e.
g.
, a dissector and retractor.
Accordingly, it is an object of the present invention to provide an improved endoscopic device, especially useful for dissecting veins or arteries.
It is a further object of the present invention to provide an endoscopic device that permits the passage therethrough and maneuverability therein of multiple instruments.
It is a further object of the present invention to provide an endoscopic device that permits more downward viewing of the target tissues, with less frequent need for retraction and cleaning of the endoscope.
It is a further object of the present invention to provide an endoscopic device for dissecting veins or arteries that minimizes damage to the target tissues.
