1. An ingress-egress apparatus for protection of a surgical work site during removal of a surgical implant therefrom, the apparatus comprising:
an inverted frustum surface comprising a sidewall defining:
a bottom open area at a base portion of the frustum surface sidewall, and
an opposing top open area at a top portion of the frustum surface sidewall,
wherein the top open area has a larger area than the bottom open area;
an ingress port located at the base portion of the frustum surface sidewall and providing fluid communication access from (i) external to the ingress-egress apparatus to (ii) the bottom open area;
an egress port located at the base portion of the frustum surface sidewall and providing fluid communication access from (i) external to the ingress-egress apparatus to (ii) the bottom open area;
an inlet line in fluid communication with the ingress port; and
an outlet line in fluid communication with the egress port;
wherein the bottom open area at the base portion of the frustum surface sidewall is a circular open area adapted to induce a vortex swirling flow when irrigating fluid is fed to the circular open area from the ingress port.
