VETERCIQNARY SURGICAL INSTRUMENT.
' a lication meanin 25,1915. seriainofsaivsy g To all whom it may concern. Be it known that I, \VILLIAM B. .OBRIE citizen of the United States,1residing at Peosta, in the county of Dubuque and State of Iowa, have invented certain'new and useful Improvements in Veterinary Surgical Instruments, of which the following is a specification.
My invention relates to veterinary surgical instruments, with special reference to instruments for removing obstructions from milk passages in the teats of"cows, and the leading object is to providean instrument that may be inserted in the teat and cut out the obstruction and at the same time remove it from the teat.
It essentially consists in a circular piece of metal, cone pointed at one end and hollowed into cup shape at the other end, which end is provided with a circular cutting edge, and to the center of this piece, within the cutting end, is attached a small rod which also serves as a handle for operating thedevice.
Aroundthis handle is a tube that extends partly the length of the handle and is adapted to readily slide along on the handle and with this instrument is a strap or other means for compressing the teat.
The following specification will point out in detail the manner in which it is constructed and mode of operation when read in con.'
nection with the drawings accompanying the same and forming a part hereof.
' Figure 1 is a perspective view of my device. Fig. 2 is a longitudinal section. Fig. 3 shows a sectional view of a teat with my device therein and the obstruction compressed against the handle before the opera- Fig. 4: shows a sectional view of the device after the obstruction has been cut off and about to be removed. Fig. 5 is a perspective view of a strap or rubber band used in connection with the instrument.
Like characters of reference denote corresponding parts in each of the figures.
Referring to the drawings 2 represents the device, 4 the head, 5 the handle." The head 4; is made of metal and is formed into a cone 8 at one end and hollowed out into a V cup 10, at the end. The outer edges of the cup 10 is provided with a cutting edge 12 that extends entirely around the head. I/Vithin the center of the cup is secured an operating rod 5 which also serves with the ring 141: at the outer end, asa-handle.
Around the handle isa tube, not as long as thehandle but adapted to slide readily on the handle. The circumference. of which tube is-praetically the sameas thatof the cuttingedge of the head. g V
I For the purpose of compressing the teat so that the cutting edge willengage the obstruction and sever it at its base, there is provided, preferably, a strap of leatherQO having at one end abuckle 22: and provided with aItongue 243:. 1
The manner: of operating is substantially as follows; the head 4 is inserted in the teat until the cuttingedg'e 10 haspassed atrifie I beyond the obstruction 16 in the teat 15,
and the tube is shoved along a short distance in the teat, then thestrap 20 is brought. around the teat overthe obstruction and buckled. This presses the teat and the 0bstruction close down onto the handle 5 and within the line of travel of', the cutting edge. The operator takes hold of the tube 6 and the handle 5 at the ring 14; and pushes up the tube until it comes to the obstruction then he draws the head ldown and at the same time pushes up the tube 6 and cuts off the obstruction against the end of the tube.
; Specification of Letters Patent." Patented Jan. 4, 1916.
lVhen the cutter meets the end of the tube 7 head and this brings the obstruction out of theteat.
It. will be seen that by compressing the teat by the strap downon the handle, that allof the obstruction will be cut-off and drawn out and the milk passage will be freed of all obstruction. l
It is manifest that means, other than a strap or rubber band may be used to com press the obstruction in the teat without departing, in any manner, from the spirit of my invention. 7 1
Having now described my invention What I claim is:
1. In a device of the character described, a head smaller" at itsouter end, a cutting edge on the opposite end, a handle attached to the head, a tube adapted to slide on said handle, and means for compressing the teat.
2. In a device of the character described, a head of cone shape at one end and provided' with a circular cutting edge on the opposite end, a handle attached to the head Within the circle of the cutting edge, a tube adapted to slide on said handle, and means for compressing the teat against the handle.
3. In a device of the character described, a head of cone shape at one end and of cup shape at the opposite end and provided with a cutting edge around the edge of the cup, a handle attached to the head Within the cup, a tube adapted to slide on said handle, and means for compressing the teat upon the handle.
4L. In a device of the character described, a head of cone shape at one end and having a circular cutting edge on the opposite end, a handle attached to the head Within the circle of the cutting edge, a tube adapted to 5. In a device of the character described,
a head of cone shape at one end, cup shape at the opposlte end and provlded W1th a cutting edge around the edge of the cup, a handle attached in the cup to the head, a tube adapted to slide on said handle and form a cutting block for said cutting edge, and means for compressing the teat against the handle between the cutting edge and the end of the tube.
6. In a device of the character described, a head of cone shape at one end and cup shape at the opposite end and provided With a cutting edge around the cup, a handle attached to the head Within the cup, a tube adapted to slide on said handle and form a cutting block for the cutting edge of the head, and a strap for compressing the teat on the handle between the cutting edge and the end of the tube.
In testimony whereof I affix my signature in presence of two Witnesses.
