Abstract
Abstract A cervical biopsy-sampling instrument is disclosed which comprises an aspirator having a spatulated sampling tip thereon by which a mucus aspirate and surface scrapings are collected from the cervix for cytological diagnosis. The tip is flexibly connected with the aspirator so that it can follow the relative deflection of the cervical canal when the canal is out of alignment with the vaginal canal. In addition, the scraping edge of the tip is defined on at least one side by a profile face of the tip which is substantially flat over the entire profile on that side, so that the edge and face of the tip can be applied to a smear plate in the manner of a spatula for purposes of transferring the scrapings directly to the plate from the tip.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A cervical biopsy-sampling instrument comprising an aspirator tube having a plunger therein which is equipped with means that extend from the proximal end of the tube for reciprocating the plunger within the tube, a sampling tip which is disposed at a location spaced relatively forwardly from the distal end of the aspirator tube, and which includes a pipette that is adapted to be inserted into the endocervical canal, and has a laterally projecting lobe thereon, the relatively forward edge of which lobe is adapted for scraping the portio vaginalis when the pipette is inserted into the endocervical canal, and the profile face of which on one side thereof is adapted to be used as a spatula in spreading the scrapings on a smear plate, and means interposed between the tip and the distal end of the tube which define a flexible joint whereby the tip can flex in relation to the tube, there being a passage through the joint to provide intercommunication between the pipette and the tube for withdrawing a sample of mucous from the canal into the pipette with the tube.
Claim 2
Dependent Claim
183 words
A cervical biopsy-sampling instrument comprising an aspirator tube having a plunger therein which is equipped with means that extend from the proximal end of the tube for reciprocating the plunger within the tube, a sampling tip which is disposed at a location spaced relatively forwardly from the distal end of the aspirator tube, and which includes a pipette that is adapted to be inserted into the endocervical canal, and has a laterally projecting lobe thereon, the relatively forward edge of which lobe is adapted for scraping the portio vaginalis when the pipette is inserted into the endocervical canal, and the profile face of which on one side thereof is adapted to be used as a spatula in spreading the scrapings on a smear plate, and means interposed between the tip and the distal end of the tube which define a flexible joint whereby the tip can flex in relation to the tube, there being a passage through the joint to provide intercommunication between the pipette and the tube for withdrawing a sample of mucous from the canal into the pipette with the tube.
Claim 3
Dependent Claim
29 words
The cervical biopsy-sampling instrument according to claim 1 wherein the flexible joint includes a flexible sleeve which is interposed between the tip and the distal end of the tube.
Claim 4
Dependent Claim
31 words
The cervical biopsy-sampling instrument according to claim 2 wherein the sleeve is corrugated to allow for both limited transverse and limited axial movement of the tip in relation to the tube.
Claim 5
Dependent Claim
33 words
The cervical biopsy-sampling instrument according to claim 1 wherein the face of the lobe is substantially parallel to the pipette and substantially flat over the entirE profile of the lobe on that side.
Claim 6
Dependent Claim
49 words
The cervical biopsy-sampling instrument according to claim 1 wherein the relatively forward scraping edge of the lobe has a smoothly curved indentation therein, the valley of which is interconnected with the pipette by a smoothly curved fillet which is adapted to project into the endocervical canal with the pipette
Claim 7
Dependent Claim
52 words
The cervical biopsy-sampling instrument according to claim 1 wherein the sampling tip comprises a flat generally heart-shaped spatula which is bisected by the pipette into laterally opposing lobes having coplanar faces thereon which are substantially parallel to the pipette and substantially flat across the entire profile of the spatula on each side.
