Claim 5
Dependent Claim
174 words
An instrument for determining anatomical characteristics of body cavities and passageways or the like comprising an elongated probe adapted to be inserted in a body cavity, passageway, or the like; expandable means at one end of said probe; means connected to said expandable means for selectively controlling said expandable means; a stop slidably mounted on said probe and having a stop surface facing said expandable means and adapted to engage a body surface surrounding a body cavity, passageway or the like when said probe is inserted thereinto; a coil spring on the exterior of and surrounding said probe and biasing said stop toward said expandable means; a protective housing including a hollow cylinder of transparent material about said probe and surrounding said spring for all positions of movement of said stop on said probe and including a measuring scale extending along said probe; index means for indicating the position of said stop in relation to said scale; and means positioned within said cylinder for connecting said index means to said stop for movement therewith.
