Definitions

  • Medbery Attorney-Edward H. Loveman 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.
  • the invention device disclosed herein is designated to bridge this diagnostic gap between the office Pap Smear and the hospital cold cone thereby preserving many women from the risk of nondetection on one hand or the discomfort, danger, and expense inherent in a major operation.
  • the invention in this case consists of an elongate tool or implement 10 for clinical or office use by physicians, and comprising a handle portion 12 and a blade portion 14.
  • Blade portion 14 is essentially flat or planar and has a pair of oppositely facing and spaced-apart edges 16 and 18 adapted to scrape the entire circumference of the squamo columnar junction area with a deep-ploughing actionv
  • a storing groove or trough 20 and 22 adjoins each of the edges 16 and 18, respectively, and receives the samplings progressively obtained by the stated edges during rotation of the instrument. Rotation is accomplished by force manually applied to handle portion 12.
  • FIG. 6 shows a cross-sectional view taken along line 66 of FIG. 1.
  • implement 10 may be seen to comprise handle portion 12 and flat blade portion 14 integrally formed therewith of substantially rigid material such as plastic.
  • Blade portion 14 has oppositely facing substantially parallel surfaces 13 and 15 seen particularly from FIG. 2, and a structurally weakened neck portion 17 defined by a transverse groove across both surfaces 13 and 15 resulting in a reduced crosssectional thickness as shown more clearly in FIG. 5.
  • Blade portion 14 is an elongate cutter shaped along the sides thereof to correspond generally with the natural contours of the cervix ofa human uterus as required for maximum effectiveness in performing its intended function.
  • the opposite side contours defined by thin lips or cutting edges 16 and 18 may be seen to diverge from relatively close proximity therebetween near distal end 19 to a maximum width at oppositely directed projections 21 and 23.
  • the edges 16 and 18 thus describe a conical path when implement 10 is rotated by manual force applied to handle 12. If only one edge were made to function as a specimen collector, the lateral forces on such blade would be unbalanced during rotation of implement 10 and its longitudinal axis in the manner described below, whereby two oppositely directed edges are preferred in the symmetrical relationship suggested by edges 16 and 18.
  • a separate recessed groove adjoins each of the edges 16 and 18 as suggested by grooves 20 22, respectively, and extends coterminally therewith so as to describe the same conical path as edges 16 and 18 during rotation of implement 10 as discussed abovev
  • the number of edges l6, 18 of adjoining grooves 20, 22 could be more than two in number, but as a practical matter only two of each, as suggested by the structure shown in the accompanying drawing, have been found to provide all the advantages sought in this case.
  • the angularity of the edges 16, 18 and adjoining grooves 20, 22 could be varied slightly, the preferred arrangement is for the included angle to be from about 10 to 30 between the edges in that portion between distal end 19 and line 44 in FIG. 1, for example, increasing to about 45 to 60 included angle in the flared portion from line 4-4 to oppositely extending projections 21 and 23.
  • edges 16, 18 are directed in opposite directions as seen in FIGS. 3 and 4.
  • Distal end 19 of implement 10 has a bulbous or mushroomshaped protuberance extending therefrom and comprising button or dome 25 connected to end 19 by recessed shaft 26 of lesser diameter than portion 25. Dome 25 has a peripheral scraping edge 30 thereon.
  • Handle portion 12 may be cylindrical, but in the preferred embodiment has a plurality of longitudinal strengthening ribs 27 symmetrically arranged about the center axis 28 of the handle as seen particularly from FIG. 6.
  • implement 10 is initially introduced onto the cervical canal with distal end 19 projecting therewithin and with oppositely directed projections 21 and 23 bearing against the outer surfaces of the squamo columnar junction. While thus positioned, implement 10 is rotated 360 about axis 28, although such rotation could obviously be more than one complete turn.
  • edges 16 and 18 bear uniformly throughout their length with the surfaces which they contact and which have substantially the same contours as the path defined by the edges during the stated rotation.
  • edges 16, 18 and grooves 20, 22 as discussed above results in a plowing and scraping action whereby edges 16, 18 detach cells, surface tissue and other diagnostic material from the test situs, such material being channeled into the mentioned grooves as it is progressively accumulated.
  • the structure and method in this case provide a rapid and effective means for collecting diagnostic matter and with a minimum of specialized skill.
  • the plowing and scraping action of blade edges l6, l8 assures complete collection of matter throughout the entire test area whereby a comprehensive sampling is achieved, and further assures that such matter will include surface tissue structure rather than loose cells only.
  • the area thus sampled is wider and of greater yield potential than could be accomplished by multiple biopsies.
  • the tissue sheared from the test surface is shallow, so that pain or postoperative bleeding are not encountered in using implement 10.
  • the procedure can be carried out simply during the course of a pelvic examination in a medical office and requires no elaborate medical or hospital surgery equipment.
  • 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
  • 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 situsv 2.
  • 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.
  • 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.
