`Patented Feb. 26, 1952 UNITED STATES PATENT OFFICE 2,587,486 cERvICAL SPECULUM Jerome Kogan, Stamford, N. Y. 'application July 1 3, i950, serial No. 173,615
The present invention concerns a cervical specg claims. v'(cl. 12s-17) ulum, an instrument used by doctors to viewthe isfactory for this purpose now exists.
interior of the cervical canal. No instrumentfsatl-V'VV The ,principal disadvantages of instruments used for thispurpose are that the partsI oftthe instrument which Vengage the cervix in order to dilate it for 'inspection defeat their purpo'sewto -ai large degree by covering the tissue desired to be visualized; in addition the body of the instrument is in the line of sight between the cervix andthe physicians ye, and the formation of the human body prevents any considerable manipulationl of the instrument to overcome this. y l
An 'objectof the present invention is the P179- vision of aspeculum in which the partwhich engages the cervix is of wire or similar construc- -tion so that it may enter and dilate the cervix Without blocking the physicians view thereof.'
Another object is that the body of the instrument shall be offset from the physicians line of sight to the cervix.
Other objects will appear as the description proceeds.- l l In accomplishing the above objects a speculum is provided having a scissors like body comprising handleA portions pivoted together, finger rings, blade' portions extending from thehandle portions on the other side of the pivot, arm portions extending laterally from the blade portions, and elongated loop portions extending rst toward each'.l other fromv the arm portions and finally in 4a direction away from the pivot,"` the terminal portions being substantially parallel when" the speculum is in closed position.
In operation, the terminal portions of the loops areiin'serted in the mouth of the cervical'canal andfthe cervix gently dilated by moving the handlesof the instrument. A good view ofy the tiSSll'elisl `possible because of the wire or similar constructionof the loop, and because the handles an'dlbla'd'es are offset from the loops. y
"Qth'erlobjects of this invention will in partbe obvio andfin part hereinafter be pointedloiit. Thein-vention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be exemplied in the constructions hereinafter described. In thev accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention:
Figure 1 is a plan view of the speculum.
Figure 2 is a section on the line 2--2 of Figure 1.
` Figure 3 is a side elevation looking in the direction of arrow 3 of Figure 1.
Referring now in detail to the drawings, the improved cervical speculum III comprises the handles II with ngerrings I2, handles II being joined by the pivot I3 and each handle being integral with a blade portion I4. The medium line between the blades I4 is inclined approximately thirtyV degrees from the prolongation of the median line between the handles II.
The arms I5 extend laterally from the blades I4 and su'bstantially parallel to the axis of'pivot I3.
The elongated loops I6 have inner portions I1 extending inwardly toward each other and terminal portions I8 extending away from pivot I3. Inner portions I'I -comprise the legs I 9, 20 extending substantially parallel one to the other and integral with their respective terminal portions.
vThe speculum is preferablyy made of corrosion resistant material such as stainless steel, and the loops I6 may be integral therewith or may be of stainless steel wire or the like rmly connected thereto.
In operation, the loops I6 are engaged in the os externum, the terminal portions I8 entering the canal and portions II acting as shoulders to i limit the inward advancement. The mouth and canal can then be gently dilated to permit convenient inspection ofthe tissue, the wire construction of the loops permitting a good view of the tissue. The body of the instrument, comprising the handles I I and blades I 4 is oiset from the physicians line of sight.
It will thus be seen that there is provided a device in which the several vobjects of this invention are achieved, and which is well adapted to meet the conditions of practical use.' As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to" be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
f What is claimed is:
1. A cervical speculum comprising the combination with a pair of handles, a pivot connecting said handles and a blade portion connected to each of said handles and extending therefrom on the opposite side of said pivot, of arm portions extending from said blade portions substantially parallel to the axis of said pivot. an elongated loop portion connected to one of said arm portions. said loop portion comprising an inner portion extending substantially perpendicularly from said arm portion toward said other arm portion, said loop portion further comprising a terminal portion extending substantially perpendicularly from said inner portion and away from said pivot, and means mounted on said other arm portion and cooperating with said loop portion for engaging and distending the mouth of the cervix.
2. In a cervical speculum acoording to claim 1, said cooperating means being a loop substantially identical to said rst mentioned loop.
