Endoscopic bone debridement
First Claim
1. A device for use in treating osteonecrosis, comprising:
- an osteoendoscopic cylinder having a distal endoscopic end, a proximal handle end, an inner visual surface and an outer contact surface, wherein the distal endoscopic end includes an orientation mark along the inner visual surface and passing through a centralizing sleeve, said centralizing sleeve adapted to establish a hermetic seal at a juncture of the centralizing sleeve and a bony contact surface, said centralizing sleeve further comprising an inner surface wherein the outer contact surface of the osteoendoscopic cylinder and the inner surface of the centralizing sleeve are adapted to establish a hermetic seal at a juncture thereof, said osteoendoscopic cylinder further comprises an opening adapted to communicate with a vacuum apparatus wherein said orientation mark and said opening are aligned so as to provide spatial orientation of the bony contact surface.

Abstract
The invention described includes an osteoendoscopic cylinder for tamponading bleeding along a longitudinal canal surface of an osteocentral canal of a femoral neck so as to allow endoscopic visualization of a segment of osteonecrotic bone within a femoral head. The osteoendoscopic cylinder is of a dimension adapted to receive an endoscope therein and includes an inner visual surface and an outer bony contact surface. An orientation mark along the inner visual surface is of a size and dimension to ensure a first visualization thereof with the endoscope. The first visualization is of an effect to allow spatial orientation of the endoscope within the femoral head. A side opening proximally situated thereabout a proximal handle end is of a size and dimension adapted to mount a vacuum apparatus comprising of a transparent tube.
