RIGID ARTHROSCOPE SYSTEM

摘要

A reinforced arthroscope comprising external ribs to provide for a number of separate fluid channels, such as inflow, outflow and interstitial tissue drainage, when the arthroscope is slipped into a disposable external sheath. The arthroscope is constructed to be sufficiently rigid so as to penetrate and move within a joint without damaging the rod optics inside. The externality of the arthroscope channels allow for cleaning and sterilizing the scope between uses.

1. An arthroscope system comprising:
an arthroscope comprising a plurality of external ribs extending radially from and running longitudinally along the outer surface of the arthroscope; an external sheath having an inner surface and a central lumen; wherein the external sheath has an internal diameter closely matching the external diameter of the arthroscope whereby the inner surface of the external sheath, in conjunction with the ribs, define a plurality of fluid channels longitudinally extending within the arthroscope system.
