Abstract
An endoscopic system and method for performing endoscopic surgery at locations where tissue inserts into bone which including a sleeve member for forming an opening in the body between tissue and bone having a tube, an instrument portion interconnected to a register portion, open ends, slot segments extending inwardly from said open ends, access opening for accessing the interface of tissue and bone, and an obturator configured for inserting slidably into the sleeve member and in the body between tissue and bone.
Claims13
A system for use in performing endoscopic surgery, the system comprising:
- an elongated tubular sleeve member with open ends, said sleeve member forming a slot extending longitudinally along said sleeve member and a portal opening along the length of said slot with the portal opening having a greater width than said slot for accessing an adjacent interface of tissue and bone;
- an obturator having a shaft to allow for inserting slidably into said sleeve and a tip at a distal end of said shaft configured for guiding and positioning the sleeve during insertion of said sleeve into the body using the residual force of soft tissue, said tip having an upper edge longitudinally aligned with the surface of said shaft and an opposing, angled guiding edge extending downwardly and rearwardly from said upper edge.
A device for use in performing endoscopic surgery within a human body comprising:
- a tubular sleeve adapted to penetrate the human body and having opposite open ends and defining an interior passageway extending the length of said sleeve, one of said open ends adapted for the introduction of an endoscope into said passageway and the other end adapted for the introduction of surgical instruments into said passageway, said sleeve defining a slot extending longitudinally along said sleeve for accessing body structures adjacent said sleeve with the endoscope and surgical instruments;
- and
- an obturator having a shaft configured to allow said shaft to be slidably inserted within said passageway and a tip formed at a distal end of said shaft to extend outward from said sleeve when said obturator is inserted into said sleeve, said tip forming an upper edge longitudinally aligned with the surface of said shaft and a guiding edge angled downward and rearward from said upper edge to form an angle to a lower surface of said shaft, said guiding edge guiding the movement of said sleeve when said sleeve and said inserted obturator are inserted the body.
A surgical device for use in performing endoscopic surgery within a human body comprising:
- a tubular sleeve adapted to penetrate the human body and having opposite open ends, said sleeve defining an interior passageway extending the length of said sleeve, one of said open ends being adapted for the introduction of an endoscope into said passageway and the other end being adapted for the introduction of surgical instruments into said passageway, said sleeve having a slot formed along its longitudinal length to intersect said interior passageway, and a portal opening formed intermediate the length of said slot and having greater circumferential width than said slot for enabling greater access to the adjacent human body for manipulation of said endoscope and surgical instruments;
- and
- an obturator having a shaft with a forward distal end and configured to allow said shaft to be slidably inserted within said passageway and a tip formed at said distal end to pass through and extend outward from said sleeve when said obturator is inserted into said sleeve, said tip including an upper edge longitudinally aligned with the surface of said shaft, and a guiding edge angled downward and rearward from said upper edge to form an angle with a lower surface of said shaft, said guiding edge guiding the movement of said sleeve when said sleeve and said inserted obturator are inserted into the body.
