<p>A medical instrument is provided with a chemiluminescent light source for inspection and examination of a body. The light source (26) comprises at least two compartments (30, 32) separated by a barrier (34), each compartment filled with a suitable fluorescing component, such that by breaking the barrier between the compartments and causing admixing of the components, a chemical reaction occurs which produces the chemiluminescent effect. In a particular embodiment an endoscopic instrument, such as a vaginal speculum, is provided having cooperating upper and lower dilator blades (4, 6) pivotally connected to each other, a means (22) associated with at least one dilator blade for releasably engaging thereto a chemiluminescent light source adapted to direct its light intermediate the dilator blades in their spaced apart position to illuminate the body cavity being examined.</p> |
