Description

Novl 2, 1937. A. H. JUNGE VETERINAR? INSTRUMENT Filed April 2, 1955 gmwm Ari/Mr E Jiuge Gum/wan Patented Nov. 2, 1937 UNITED 1 Claim.

My invention relates to a veterinary instrument of the obstetrical type for use in connection with cows and mares.

It is well known that a calf or fetus lies on its breast within the uterus, but due to the fact that it rolls on its back, or nearly so, it takes the uterus along with it resulting in the twisting or torsioning of the uterus neck whereby the latter is closed to parturition.

It is the aim of my invention to overcome the objection referred to, and to this end, my invention resides in the providing, in a manner as hereinafter set forth, means for removing the twist or torsion in the neck of the uterus, as well as positioning the calf or fetus in a normal anterior pres.- entation or a posterior presentation.

Further objects of my invention are to provide, in a manner as hereinafter set forth, an instrument for the purpose set forth which is simple in its construction and arrangement, strong, durable, compact, thoroughly efficient in its use and comparatively inexpensive to manufacture.

To the above ends essentially and to others which may hereinafter appear, my invention consists of such parts and such combination of parts which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a view illustrating the uterus of a cow having a calf arranged therein and further showing the application of the instrument, in accordance with my invention, for removing the twist or torsion in the neck of the uterus and changing the position of the calf, and

Figure 2 is a perspective view of the veterinary instrument, in accordance with my invention.

With reference to the drawing. 3, 4, and 5 indicate respectively a cow, its uterus and the neck of the latter. Within the uterus is shown a calf 6 lying upon its back.

The instrument, in accordance with my invention, includes an elongated stem 1 of circular cross section and of the desired diameter and length. The inner end of stem I merges into a closed loop or eye 8. Theouter end of stem '1 merges into a combined diverging and converging head 9 merging into a semi-circular flat protuberance l0 intersected centrally by the longitudinal median of the head. The latter diverges for the greater portion of its length from stem '5 and then converges into the inner ends of the sides of the protuberance iii. The edges and faces respectively of the head and protuberance are rounded and flat. The faces of the protuberance form flush continuations of the faces of the head. The thickness of the head and protuberance is less than the diameter of the stem. The head, in proximity to its point of mergence with the protuberance, is provided with an opening i i. The head 9 is substantially of pear-shaped contour. The side edges of said head are of compound curvature. Carried by the head is a flexible element of the desired length and which, by way of example, is in the form of a chain i3 which extends through opening II and is designed for forming an adjustable loop lid. The chain i3 is provided at one end with a split retaining ring it of greater diameter than opening H and at its other end with a rectangular endless link l5 having its width greater than the diameter of chain it.

When using the instrument, the chain i3 is passed through link l5 to form a loop lt The chain is then passed through opening i i and connected to head 9 by ring M. The veterinarian then places the loop la in the uterus and slips it over a leg of the calf or fetus. The veterinarian guides the instrument in the uterus, while an assistant revolves the stem through the medium of a bar l6 extended through loop or eye 8 until the twist or torsion is removed from the neck 5 of the uterus t. The non-looped portion of chain I3 winds on rod 1 until loop Et is tight around the leg of the calf or fetus. The stem l is turned either clockwise or anti-clockwise, depending upon what direction the twist in neck 5 extends. During the removal of the neck twist or torsion, the calf or fetus is shifted from the position shown in Figure 1 to lie in a normal anterior presentation. It is to be understood that the instrument may be employed in the same manner as on a posterior presentation. It is also to be understood that the instrument may be connected to the nose, head or neck of the calf or fetus.

What I claim is:

In a veterinary instrument; a straight, elongated revoluble metallic stem having an integral endless part at its rear end forming a loop for the passage of a revolving means for the stem and an integral fiat oppositely flared head part at its other end formed with curved side edges, said head part being provided intermediate its ends with an opening, a metalic chain extending through said opening, a removable metallic ring attached to one end of said chain and coacting with the head part for connecting the head part and chain together, said chain adapted to have a portion thereof wind on said stem, on the revolving of the latter and an enlarged metallic link carried by the other end of said chain for the passage of a stretch of the latter and coacting with said stretch to form an adjustable metallic loop adjacent that portion of the chain wound on said stem.
