ABSTRACT:
A disposable medical instrument and light pipe illumination assembly fabricated of synthetic plastic material. When put to use, the instrument, such as a surgical retractor, assumes a position at which its operative section lies adjacent the field of medical interest, such as a body cavity or surgical site. Joined to the instrument is a short flexible light pipe whose optical inlet end is coupled to a light source and whose optical outlet end is next to the operative section to project light into the field. The outlet end of the light pipe is sheathed in a bendable tubular neck having dead-soft characteristics whereby by bending the neck, the user is able to orient the outlet to direct the projected light toward a desired region in the field of interest.
