First Claim
1. An instrument for determining anatomical characteristics of body cavities and passageways or the like comprisingan elongated hollow sleeve adapted to be inserted in a body cavity, passageway, or the like;
- expandable means at one end of said sleeve;
a handle at the other end of said sleeve;
an elongated rod slidably received within said sleeve and connected to said expandable means;
means connected to said handle for selectively sliding said rod to operate said expandable means;
a stop reciprocally mounted on said sleeve 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 sleeve is inserted thereinto;
a coil spring mounted on the exterior of and surrounding said sleeve between said stop and said handle and biasing said stop toward said expandable means;
a measuring scale mounted in fixed relation to said sleeve;
index means for indicating movement of said stop in relation to said scale;
means for connecting said index means to said stop for movement therewith; and
a protective housing extending from said handle about said sleeve and surrounding said spring for all positions of movement of said stop on said sleeve.

Abstract
A sound for uterine measurement including an elongated probe provided with expandable wings at one end. A button may be selectively moved to control the extension or collapse of the wings and a stop is reciprocally mounted on the probe and has a stop surface facing the wings which is adapted to engage the cervix. A coil spring surrounds the probe and biases the stop toward the distal end of the sound and a measuring scale is carried by the instrument. A moveable index point is provided and connected to the stop so as to cooperate with the scale depending upon relative positioning of the stop on the probe. A protective housing surrounds the spring for all positions of movement of the stop to prevent the spring from coming in contact with the tissue of a patient. Preferably, the protective housing is transparent and carries the scale with the index being movable within the housing.

4. 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. - View Dependent Claims (5)
