VETERINARY VAGINAL SPECULUM.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed April 6, 1908. Serial No. 425,507.

To all whom it may concern:

Be it known that I, IRA Faster, a citizen of Canada, residing at Olds, in the Province of Alberta, Canada, have invented new and useful Improvements in Veterinary Vaginal Specula, of which the following is a specification.

My invention pertains to veterinary surgical instruments; and it has for its object to provide a simple and inexpensive vaginal speeulum constructed with a view of being used to advantage in spaying cows by what is known as the Charlier process.

W' ith the foregoing in mind, the nature of the invention and its novelty, utility and practical advantages will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure l is a side elevation of a veterinary vaginal speculum constituting a practical embodiment of my invention. Fig` 2 is a detail section illustrating the manner in which I prefer to fix the forwardly extend! ing projection of the instrument to the curved portion of the body thereof. Fig. 3 is a detail view, partly in elevation and partly in section, illustrating a modification hereinafter referred to.

Referring by letter to the said drawings and more particularly to Figs. I and 2 thereof: A is the body of my novel speculum which is formed of a resilient, steel rod, and is preferably, though not necessarily, provided at its rear end with a handle loop a. The major portion of the said body A is straight, and at the forward end of the said straight portion the body is provided with a curved portion c which extends lat erally outward from the straight portion, then forwardly and then laterally inward and terminates in a transverse end portion d. On the said transverse end portion (l of the body A, at an intermediate point in the length of said portion d a forwardly extending projection B is provided. This proj ection B may be fixed to the transverse body portion d in any manner consonant with the purpose of my invention though I prefer to rivet it to said portion after the manner shown in Fig. 2.

In lieu of the body A a. body A such as shown in Fig. 3 may be employed. This body A comprises two sections one of which is screwed into the other, and when the said sections are separated it will be manifest that the instrument may be conveniently carried in the pocket.

The practical use of my novel speculum is as follows: The operator introduces his right hand into the vagina of the cow or mare to be spayed, and then with his left hand passes the speculum into the vagina, and then, after feeling for the mouth of the womb with his right hand, places the projection B of the speculum in the mouth. With this done the operator holds the handle of the speculum in his left hand and presses forward on the speculum so as to stretch the vaginal wall lengthwise which enables him to make the incision at any desired part of the vagina. The projection B is simply for holding the forward end portion d of the speculum over the mouth of the womb while the operator makes the incision with an instrument held lin the right hand.

It will be readily gathered from the foregoing that my novel speculum is advantageous in that it can be easily inserted through the vulva after the right hand is inserted, and in that its shape enables the operator to turn it into any desired position after the projection B has been positioned in the mouth of the womb. When the incision through the vaginal wall is made, the specu lum is withdrawn, and then the ovaries may be detached in any manner desired.

In addition to the practical advantages hereinbefore ascribed to my novel speculum, it will be noted that the speculuin is simple and inexpensive in construction and is well adapted to withstand rough usa e.

The construction herein illustra ed and described constitutes the best practical embodiment of my invention of which I am cognizant, but it is obvious that in the future practice of the invention such changes and modifications may be made as fairly fall within the scope of my invention as dened in the claim appended.

I am well aware of the Letters-Patent for a surgical instrument, No. 322,198, granted to one Poynor, under date of July 14, 1885, and make no claim to anything in common with what is therein disclosed.

What I claim and desire to secure by Letters-Patent, is:

The herein described device consisting essentiall of a rod like body formed of one piece o material and having a straight portion and a curved portion which extends laterally outward from the forward end of the straight portion and then forwardly in n plane parallel to that of said straight p0rtion and also having a transverse straight portion which extends from the end of the curved portion remote from the first nientioned straight portion and also extends at a right angle to the latter and to a point con`A siderably beyond the plane thereof, Iand a 10 projection carried by and extending for- Wardly from the transverse straight portion and arranged in alinenient with the first mentioned Straight portion of the body.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
