Abstract
The present invention is directed to a laminar flow endoscopic instrument for laminar transmission of irrigation fluid between an incision towards a zone of visualization associated with a surgical site, the endoscopic portal comprising an osteoendoscopic cylinder having an outer contact surface encircling an inner visual surface and extending between a proximal handle end and a distal endoscopic end with a directional surface extending therefrom and providing laminar flow of irrigation fluid.
Claims10
An endoscopic portal for laminar transmission of an irrigation fluid from an incision towards a zone of visualization associated with a surgical site, said endoscopic portal comprising:
- an osteoendoscopic cylinder having an outer contact surface encircling an inner visual surface and extending between a proximal handle end and a distal endoscopic end;
- a handle extending from the proximal handle end and presenting the osteoendoscopic cylinder for coaxial receipt of a surgical instrument along said inner visual surface;
- and
- a directional guide associated with said distal endoscopic end having a directional surface providing laminar flow of irrigation fluid longitudinally towards the surgical site.
The device according to claim 5, further comprising a proximal stabilizing support pair dimensioned to slidably receive a surgical instrument while restricting fluid flow at the juncture of said proximal stabilizing support pair and said surgical instrument, whereby one of said proximal stabilizing support pair is located between the osteondoscopic cylinder and said side opening and the other one of said proximal stabilizing support pair is located between said proximal handle end and said side opening.
An endoscopic portal extending between an incision and a surgical site, said endoscopic portal comprising:
- an osteoendoscopic cylinder having an outer contact surface encircling an inner visual surface and extending between a proximal handle end and a distal endoscopic end;
- a handle extending from the proximal handle end and presenting the osteoendoscopic cylinder for coaxially receipt of a laparoscope along the inner visual surface;
- a proximal stabilizing support dimensioned to slidably support said laparoscope received by said osteoendoscopic cylinder,
- at least one fastening member associated with said handle for releasable engagement of said laparoscope, and
- a directional guide associated with said distal endoscopic end having a directional surface providing laminar flow of said irrigation fluid longitudinally towards a zone of visualization associated with the surgical site.
A laminar flow system presenting a zone of visualization at a surgical site, said system comprising:
- a laminar flow endoscope including an osteoendoscopic cylinder having a laminar axis, an outer contact surface encircling an inner visual surface and extending between a proximal handle end and a distal endoscopic end;
- a handle extending from the proximal handle end and presenting a lateral port of entry for coaxially receipt of a surgical instrument along the inner visual surface;
- a side opening associated with said proximate handle end and in fluid communication with said distal endoscopic end;
- and
- a directional guide associated with said distal endoscopic end having a directional surface providing laminar flow of said irrigation fluid towards the surgical site, whereby the irrigation fluid is transmitted along said laminar axis longitudinally from said distal endoscopic end through said direction guide along said laminar axis.
