A Rectal Dilator and Irrigator.
I, FREDERICK TRINDER of 27 Kennet Road, St. Peter's Park, London, W.,
Chemist and Druggist, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
"
My invention relates to an improved surgical instrument to be employed,-by
introduction into the rectum,-in the treatment of such ailments as piles, chronic
constipation, atony of the sphincters, the early stage of fistula in ano &c.-caused
by atony of the sphincter muscles, or blood statis of the veins, or arteries, of the
anus and adjacent parts. And, in order that my invention may the better be
understood will proceed to describe same, aided by the accompanying sheet of
drawings; Figure 1 being a longitudinal sectional elevational view, and Figure 2.
a plan taken on top, of the instrument or appliance herein referred to, and which
I designate a rectal dilator and irrigator. I make same in three separate
parts A, B, C, and of any suitable metal or material, say for instance aluminium,
vulcanite, celluloid, xylonite &c. The three separate parts of the instrument are
readily detached from each other and again re-attached by the respective parts
being screw-threaded as at a and b. This method of constructing the instrument
forms a special feature distinctive of my invention, on account of the purposes of
utility thereby served, as hereunder stated. Thus, the instrument may either be
used simply as a "dilator" for direct application-to the affected part-of some
" or any
remedial agent, say for instance a medicated unguent such as "vaseline
solid extract of any medicinal plant such for example as the solid extract of
trifoleum prateuse &c.-which remedial agent would be rubbed or "served
the exterior of the instrument prior to the latter being inserted in the rectum. Or,
when it is desired that the instrument should be availed of as an "irrigator" for
washing out or syringing out the lower rectum or injecting medicine, it is only
necessary to place in the interior of the instrument an ordinary urethal syringe D,
the discharge nozzle of which, fits into a corresponding orifice E at the apex of the
surrounding instrument, the head of the syringe tube or barrel being received
within the concave cap piece F of the uppermost member or lid portion, A, of the
instrument; the syringe having been previously charged with the irrigating or
cleansing fluid, or the medicine to be injected. When the instrument is simply to
be used for the dilation of the rectum for purposes of external treatment under the
first hereinbefore described mode of procedure, the syringe may be readily removed
on disconnecting--by unscrewing-the lid or cap A, from the part B; otherwise,
however, the syringe need not necessarily be removed, as the slightly protruding
bead d of the syringe piston stem, would not interfere with the manipulation of the
instrument, by the operator, at the cap F which is formed concave, as shewn, to
allow of a firm grip being ensured for the thumb and forefinger. The instrument
being, as aforesaid, in three separate, detachable parts, the interior of same may be
cleansed with great facility.

I wish it to be understood that I attach especial importance to the particular
coufiguration adopted by me for my improved instrument as shewn at Figure 1,
this having been arrived at after careful study. Thus, referring to the "waist
portion B, C, of the instrument, the concavity of this, is devised in order to ensure
that the sphincter muscles may grasp the dilator; and, the protuberant belt G is
devised to effect the necessary amount of dilation of the anus or rectum and also to

page_text: secure its self-retention therein, in connection with the relief, or cure, of the
complaints herein before referred to, by causing the blood to circulate more freely
in the veins, or arteries, at, or adjacent to the part where the instrument is applied.
This variation of contour and of dimensions at different portions of the instrument
is rendered necessary, inasmuch as otherwise, the instrument being a body or
substance foreign to the internal organs of the human system where introduced,
would be ejected by the action of the muscles unless the instrument was pressed or
held so hard, and continuously, during the operation, by the hand of the operator,
as might cause considerable pain and inconvenience to the patient
The
I propose to produce the herein described instrument in three sizes.
smallest would, preferably, be of the following dimensions, length from top of the
lid A to the discharge apex E, 34 inches: circumference of belt G, 3 inches, and
that of the narrowest of the "waist" portion B, C, 2 inches. The second size
would be preferably 4 inches by 4 inches circumference at G and 3 inches at
smallest portion of the "waist B, C. The largest size would preferably be
4 inches x 4 inches x 4 inches.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
The improved surgical instrument substantially as and for the purposes herein
set forth.
