Abstract
An implant port for repeated access to the medullary portion of bone is provided. The implant port includes an access port fittable into a surgically constructed bone orifice and an insert means that seals and fills the port volume. A penetrable insert means allows repeated access within bone using sharp surgical instruments; while an adapter means allows guided placement of a surgical instrument, such as a catheter, optical device, or rotating cutter. Skeletal surgery from the inside of bone is contemplated using the implant port provided.
Claims21
A surgical instrument port system for access to a medullary compartment of bone or cartilage and for manipulation of bone or marrow, said system comprising:
- a port having an outer surface and an inner surface, the inner surface formed by a longitudinally oriented bore, a predetermined length terminating in a first end and a second end, a plurality of longitudinally oriented flutes that penetrate the outer surface and extend from the first end for a significant portion of the port length, the flutes allowing the first end to deform for insertion into bone or cartilage, at least one bead on the outer surface adjacent to the first end, the bead locking the port in bone or cartilage when in use;
- an insert adapted to fit into the bore of the port, the insert having an insert bore contoured to matchingly fit a swivel ball;
- and
- a swivel ball having a bore therethrough for insertion of a surgically-related instrument, the insert and swivel ball substantially filling the bore of the port when positioned in the port.
A bone insert system for access to the medullary compartment of bone, consisting essentially of:
- an insert selected from the group consisting of
- i) a swivel ball having a bore therethrough, and
- ii) an insert having a bore, the insert bore contoured to matchingly fit a swivel ball, the insert in combination with a swivel ball having a bore therethrough, and
- a surgically related instrument positioned within the insert bore wherein, when in use, said system is unattached to bone cortex and is freely movable relative to bone cortex.
A bone insert system for access to the medullary compartment of bone, consisting essentially of:
- a swivel ball having a bore therethrough;
- a guide tube positioned within the swivel ball bore, the guide tube having a guide tube bore therethrough;
- and
- a surgically-related instrument positioned within the guide tube bore wherein, when in use, the system is unattached to bone cortex and freely movable relative to bone cortex.
