Feb. 9, 1954 E. J. FRICK VETERINARY MEDICAL INSTRUMENT Filed Nov. 6, 1951 INVEIYTOR. f/zwfi Mka'a 575% Patented Feb. 9, 1954 UNITED STATES PATENT OFFICE VETERINARY MEDECAL INSTRUMENT Edwin Jacob Frick, Manhattan, Kans. Application November 6, 1951, Serial No. 254,995

2 Claims.

This invention relates to improvements in veterinary medical instrument.

The principal objects of this invention are:

First, to provide a multiple purpose instrument that is extremely useful for treating cattle.

Second, to provide a veterinary medical instrument that is simple and inexpensive, while at the same time being extremely useful as a cattle tube, medicine administering instrument, fetatome, and speculum.

Third, to provide an instrument that is easily used and manipulated, and which is provided with an adjustable handle for controlling the instrument and for holding it in place.

Other objects and advantages of my invention will be apparent from a consideration of the following description and claims.

The drawings, of which there is one sheet, illustrate a preferred form of my instrument.

Fig. 1 is a perspective view of the assembled instrument.

Fig. 2 is a fragmentary end elevational view partially broken away in transverse cross section illustrating the mounting of the crossbar on the instrument.

Fig. 3 is a fragmentary elevational view partially in longitudinal cross section illustrating the construction of the end of the instrument.

My instrument consists first of a tube l of relatively light weight drawn sheet metal construction. The tube is approximately 20" long and 1 A" in diameter. The length and diameter of the tube can vary considerably from these specific dimensions, but I have found the example illustrated to be highly satisfactory. The lower end of the tube shown in Fig. 1 forms the inner end of the instrument which is inserted into a body cavity of cattle for medical or surgical purposes, and this inner end is smoothly rounded as at 2 by turning the end of the tube outwardly in a smoothly rolled bead.

Along one side of the tube are formed a series of longitudinally extending oval slots 3 which are useful in exposing the walls of the cavity through which the tube is extended for observation or surgical operation on the cavity walls.

Mounted on the outer end of the tube is a handle and adjusting member generally indicated at 4. The handle consists of a, split ring or clamp 5 that fits adjustably around sitely extending handles or arms 6 and 1 that project from the ring on opposite sides of the split in the ring. The handle 6 is conveniently formed integrally with the ring 5 but the handle I is provided with an inwardly extending bolt portion 8 on its inner end that extends through a bore in one side of the ring and into a threaded aperture 9 in the other side of the ring. The handle 1 thus forms an adjusting and clamping screw element for clamping the ring 5 about the tube to secure the handle in its adjusted position.

Each of the handles is provided with a fiat eyelet Ill near its outer end adapted to receive a bit strap for holding the instrument in adjusted position on an animal. The adjustable handle 4 can the tube and oppoin 1861, pp. 293-4.

be clamped in place on the tube either before or after insertion of the instrument into the animal, and serves as a guide for controlling the degree of insertion. It also serves to move or adjust the tube as when the instrument is used as a speculum or proctoscope for inspecting the cavity in which the instrument is inserted.

In addition to the uses of the instrument already described, it may be used to protect a flexible cattle tube inserted into an animals stomach, or it may be used in place of a balling gun for the administration of capsules or other medicines. A small light not illustrated may be mounted in various positions in the tube to illuminate the areas exposed through the inner end of the tube or through the slots 3. Because of its many possible uses the instrument is particularly useful to veterinary doctors and persons similarly occupied.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A veterinary medical and surgical instrument comprising, a rigid thin walled tube between 15" and 25" in length and between 1" and 1 in diameter, the inner end of said tube being turned outwardly in a smoothly rounded bead, one side of said tube having a longitudinally extending slot formed therein, a split ring adjust ably mounted around the outer end of said tube and having an arm extending from one side of the split in the ring, a second arm rotatably supported in the other side of said ring and extend ing oppositely from said first arm, said second arm having a threaded portion engageable in the first side of said split ring whereby said second arm constitutes a clamping element for clamping said ring and said arms to said tube, and bit strap eyelets on the outer ends of said arms.

2. A veterinary medical and surgical instrument comprising, a rigid thin walled tube, the inner end of said tube having a smoothly rounded bead therearound, one side of said tube having a longitudinally extending slot formed therein, a split ring adjustably mounted around the outer end of said tube and having an arm extending from one side of the ring, a second arm extending oppositely from said first arm, means on the ring for clamping said ring and said arms to said tube, and bit strap attaching elements on the outer ends of said arms.
