Abstract
Abstract An elongate clinical instrument comprises a blade and handle for collecting cells and tissues from body cavities, particularly for the detection of squamous carcinoma of the cervix. Two slanted spaced-apart edges on the blade tip describe a conical path during manual rotation in situ and gather specimens in troughs adjoining the edges. The blade tip is manually separable from the handle for forwarding to a pathology laboratory.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
An elongate substantially rigid implement for collecting diagnostic material in situs from body cavities, comprising: handle means at one end of said implement for manually rotating said implement about a rotational axis through the longitudinal center of said elongate implement, projection means extending radially from said handle means adjacent to and axially spaced from the distal end of said handle means, blade means secured to said handle means, said blade means including at least two spaced-apart slanted cutting edges, relative to said rotational axis, and which extend from said distal end of said implement and include the upper portions of said projection means and which describe a conical path during rotation of said implement, the lower portions of said projection means constituting a noncutting portion, each of said blade means further including a recessed groove adjoining said cutting edge and extending along the length thereof for receiving said diagnostic material collected by said edge from said situs.
Claim 2
Dependent Claim
157 words
An elongate substantially rigid implement for collecting diagnostic material in situs from body cavities, comprising: handle means at one end of said implement for manually rotating said implement about a rotational axis through the longitudinal center of said elongate implement, projection means extending radially from said handle means adjacent to and axially spaced from the distal end of said handle means, blade means secured to said handle means, said blade means including at least two spaced-apart slanted cutting edges, relative to said rotational axis, and which extend from said distal end of said implement and include the upper portions of said projection means and which describe a conical path during rotation of said implement, the lower portions of said projection means constituting a noncutting portion, each of said blade means further including a recessed groove adjoining said cutting edge and extending along the length thereof for receiving said diagnostic material collected by said edge from said situs.
Claim 3
Dependent Claim
34 words
The structure set forth in claim 1 above, further including: a structurally weakened neck portion between said handle means and said blade means for breaking the same apart by application of manual force thereto.
Claim 4
Dependent Claim
34 words
The structure set forth in claim 1 above, wherein: said elongate implement further includes at said dIstal end a domelike protuberance having means to scrape over said situs when said implement is removed therefrom.
Claim 5
Dependent Claim
45 words
The structure set forth in claim 2 above wherein said elongate implement further includes a domelike protuberance and a reduced cylindrical portion fixed to said distal end, said protuberance having a peripheral edge thereon for scraping over said situs when said implement is removed therefrom.
Claim 6
Dependent Claim
21 words
The structure set forth in claim 2 above wherein said blade means comprises at least two oppositely facing substantially parallel surfaces.
