Abstract
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.

Claim 1
Independent Claim
201 words
An instrument for determining anatomical characteristics of body cavities and passageways or the like comprising an 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.
Claim 2
Dependent Claim
201 words
An instrument for determining anatomical characteristics of body cavities and passageways or the like comprising an 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.
