INVENTOR WILL/AM 7. 1oM/as VARNEY BY 9 ATTORNEYS Patented Oct. 13, 1931 UNITED srars- WILLIAMTHOMAS VARNEY, or vAnoouvER, BRITISHOOIQUIVfBImCANADA l srncunnivi I Application filed May 22, 1929. Serial no. 3 5,13
My invention relates to improvements in speculums which are adapted for use by'the' vide means whereby the walls of the'cavity elongated members 7 having segmental inner The disc 2 can be dilated to any desired degree and so held for treatment, also to provide a structure where one or more of the dilator arms may be omitted so as to eXpose any inordinately large affected area situated on one side wall of the cavity. e I
The invention consists essentially. of a plurality of dilator arms fulcrumed adjacent one end in a retaining ring and a sleeve/ere,
tending between said arms which is adapted to spread the arms apart, as will be more fully described in the following specification and shown in the accompanying drawings, in which Fig. 1 is a general view of the invention a with the arms shown in retracted position.- I Fig. 2 is an end elevational view taken from the inner end of the arms. I r
Fig. 3 is a part elevational and part cross sectional view, the section being taken on the line 3'-.3 of Figure 1. v r
Fig. 4 is a detail view of the outer'end of a dilator arm. v e d In the drawings like characters of reference indicate corresponding parts in'each figure. p p I he numeral 1 indicates generally a retainerring which consists of a circular disc 2 having peripheral indentations '3 to provide a convenient. grip for the instrument when setting in position. v I
' is provided with a central threaded opening 4. about which. a'plurality of rectangularindentations 5 are formed, for the purpose of providing rality of dilator arms generally indicated by the numeral 6. The dilatorarms 6 consistof ends 8 of convex exterior, which are so formed that when in retracted, position the said'inner ends form substantially a semi-sphere as at may have been set; a fulcrum for a-plu- 9, see Figures'l and 2, one'segmental portion lying in close contact with that on opposite sides thereof so as to permitof the insertion" of the arms'into the cavity without discomfort=to the patient; The outer end of each arm 6 is provided with a pair of transverse members-numbered 10 and 11 respectively I which are spaced apart adistance slightly in excess ofthe thickness of the disc 2 and eX-- tending from the member 11 is a prong 12. The connecting portionof the arm which extends between the transverse members 10 and 11 is'o-f such crosssectional dimensions as to lie within one of the indentations 5 of the disc 2 and rock therein. The inner face of each of the arms is tapered from its outer end to a point intermediate its length, as at 13 the intermediate end of such taper lying rela tivelyclose to the axis of the instrument when in closed position as shown inFigure 1.
A threaded sleeve 1 1 having a'fiange 15 at one end which is provided with indentations 16 to afford a grip, is engaged in the threaded opening 4:, the end of the sleeve is tapered as at 17 and is adapted to slidably 75 1 my invention I will now briefly. explain its 5:
use. I V
As the sleeve 14 is screwed into the disc 2 the arms are swung outwardly in unison'todilate the walls ofthe cavity into which the instrument is inserted, such dilation being no effected according to the needs of the-case,'thef arms remaining in whatever position they such a position as to expose the entire af- 1995 i I" on enamlnatlon of the cavity an affected "if area-1s disclosed which is somewhat greater or;
fected area for treatment. The sleeve 14 permits the insertion of any suitable douching device, the insertion of an electric light for examination and also the use of certain instruments for the treatment of affected organs in the cavity.
What I claim as my invention is:
A speculum comprising a retaining ring having centrally located threaded opening, plurality of dilator arms mounted Within said ring, one end of the arms being in the form of a segment of a sphere a pair of spaced transversely extending members formed on the other end of the arms, a prong formed on the last mentioned end of said arms to limit the dilation of the arms, said arms being mounted Within the ring between said transversely extendlng members and a threaded sleeve in engagement With the threaded nroection of the rin for dilatin said arms.
Dated Vancouver, B. 0., this 14th day of May, 1929.
