The present invention relates to agriculture, in particular to devices for mechanization of livestock, and can be used for delivery to the cows.

Known similar devices: a device for providing obstetric care to animals SU 1736471, 30.05.92 [1], containing the pelvic thrust in the form of a rod with body weights and straps for fixation, and the support rod; a device for extracting fruit SU 1814545, 07.05.93 [2], containing the gripping jaw and educated obstetric rope grip neck.

These devices are unreliable in operation.

Also known obstetrical extractor EA-6 SU 1792325, 25.06.90 [3], containing the pelvic thrust in the form of staples, trunk rod with locking straps, tubular base, support and traction mechanism.

The disadvantage of this design is unreliable in operation.

The objective of the invention: improved reliability in operation.

This is achieved in that the device for delivery to the cows made in the form of brackets, designed to interact with the rump of the cow, and the traction mechanism. The traction mechanism is in the form of a skeleton and a carriage mounted on the frame with the possibility of longitudinal movement thereon. The carriage contains two shoulders lever, one end of which is provided with a roller, and a second arm, a hook, and spring-loaded by springs PL is the Steen and the latch, movably mounted on the frame, and the plate is installed with the opportunity to interact with the two shoulders roller lever, and the latch is interoperable with a hook carriage. To connect with each leg of the fetus cows in the device has two flexible rod, and one flexible rod attached to the eyelet of the carriage, and the second eyelet to the roller axis two shoulders of the lever. Plate and the retainer contain holes, which they installed on the frame, and the latch includes a handle.

The invention will be understood from the following description and the attached drawings.

Figure 1 shows the device for delivery to the cows, General view; figure 2 - position of the plate carriage on the frame; figure 3 - position of the latch on the frame; figure 4 - device for delivery to the cows at the position of the two shoulders of the lever in a rotated view; figure 5 - position spring-loaded plate in the rotated view; figure 6 - position of the latch in the rotated view.

Device for delivery to the cows made in the form of bracket 1 (figure 1)designed to interact with the rump of the cow, and the traction mechanism. The traction mechanism is in the form of the skeleton 2 and the carriage 3 with two shoulders lever 4 mounted on the frame 2 with the possibility of longitudinal movement thereon. One end of the two shoulders of the lever 4 includes a roller 5, and the free end of the handle 6, the Carriage 3 also contains the hook 7 and spring-loaded by springs 8 and 9 respectively of the plate 10 and the stopper 11, movably mounted on the frame 2, and the plate 10 is installed with the possibility of interaction with roller two shoulders 5 of the lever 4, and the latch 11 is interoperable with the hook 7 of the carriage 3. To connect with each leg of the fetus cows in the device has two flexible rod 12 and 13. Flexible rod 12 is attached to the eyelet 14 of the carriage 3, and a flexible rod 13 to the eyelet 15 axis 16 of the roller 5 two shoulders of the lever 4. Plate 10 (figure 2) contains the hole 17 and the latch 11 (3) - hole 18, which plate 10 and the latch 11 is installed on the frame 2. The latch 11 includes a handle 19.

Device for delivery to the cow works as follows. Flexible rod 12 and 13 (figure 1) are attached respectively to the eye 14 of the carriage 3, to the eyelet 15 axis 16 of the roller 5 two shoulders of the lever 4 and the free ends of each leg of the fruit separately. The bracket 1 is applied to the rump of the cow (not shown) and guide the frame 2 of the device in the direction of motion of the fetus. Handle two shoulders 6 of the lever 4, the carriage 3 is turned clockwise (figure 1 and 4). When exposed to the plate 10 of the roller 5 (2, 4 and 5) and the simultaneous action of the spring 8 occurs in the pair of forces, which rotates the plate 10, which leads to the fixation plate 10 on the frame 2. A further shift of the two shoulders of the lever 4 moves the carriage 3 on the frame 2 (figure 4). While the flexible rod 12 (Fig 1 and 3)attached to the eyelet 14 of the carriage 3, the effect on the stem of the fruit, it moves it to move the carriage 3 than assist the birth of the fetus. Simultaneously with the movement of the carriage 3 to the right in the frame 2, the hook 7 of the carriage 3 releases the latch 11, mounted on the frame 2 and spring-loaded by a spring 9. This spring 9 rotates the latch 11 and sets the hole axis 18 parallel to the axis of the skeleton 2 (6), which ensures the free movement on the frame 2 of the latch 11 to contact with the hook 7 of the carriage 3 in the new position.

Then handle two shoulders 6 of the lever 4, the carriage 3 is turned counterclockwise until it stops in initial position (figure 1). In this movie two shoulders 5 of the lever 4 ceases to act on the plate 10 (Fig 1 and 2), and spring 8 rotates the plate 10, sets the hole axis 17 parallel to the axis of the skeleton 2 and moves the plate 10 to the frame 2 before contact with the roller 5 (the initial position). Simultaneously, the flexible rod 13 (Fig 1), attached to the eyelet 15 axis 16 (Fig 1 and 2) roller 5 acts on the second leg of the fetus, it moves it to the travel of the roller 5, thereby assisting the birth of the fetus. From moving to the left on the skeleton 2 table 3 holds the detent 11 (figures 1 and 3), whose interaction with the hook 7 and the influence of the spring 9 causes a pair of forces, the result of which is turning FIC is atora 11 and its fixation on the frame 2. Thus, effecting oscillatory movement of the two shoulders of the lever 4, in turn affect the legs of the fetus, thereby carry out the delivery.

For the released carriage 3 on the frame 2 and return it to its original position (to the left in figure 1) affect the handle 19 of the retainer 10 (6), thereby installing the hole axis 18 parallel to the axis of the skeleton 2 and ensure free movement on the frame 2 of the retainer 11, and hence of the carriage 3.

The use of the device for delivery to cows increases the reliability of the process of birth of the calf and ensures the growth of labor productivity with delivery in 3-4 times.

SUBSTANCE: the present innovation deals with carrying out operations upon affected bones in canine and feline limbs. The suggested clamp for intramedullary osteosynthesis has a screw and a rod. The latter is designed to be hollow with inner thread for screw's passage from one side, and from another side it has two leaves with protrusions. Leaves are conical with possibility for wedging. Protrusions are designed at the ends of leaves being 1.0-2.0 mm against the surface of leaves. As a result of applying the suggested clamp one should exclude clamp's migration out of the bone at postoperational period, the procedure of operation is simplified, the time to conduct operation is shortened and the chance for osteomyelitis development is decreased along with other complications.

EFFECT: decreased traumatism of operated bone.

SUBSTANCE: method involves fixing cranial and caudal regions of both pelvic bones. Bones and/or ventral pelvic half-ring fragments are reduced under apparatus-mediated fixation conditions. Residual dislocation of pelvic bones in sacroiliac symphysis zone and/or that of sacrum fragments are eliminated under apparatus-mediated fixation conditions. Iliac bones are first reduced to the level of anatomical arrangement of sacroiliac symphysis and/or sacrum fragments in particular cases of bilateral vertical fracture-dislocations of animal pelvic ring. First, intermediate fragments of the bones are juxtaposed along injury line and intermateably fixed with one of adjacent fractured bone fragments and then pelvic ring bone dislocation is eliminated in particular cases of vertical fracture-dislocations accompanied by bilateral longitudinal fracture of sacrum and/or recess branches of pubic and suture branches of ischial bones. When fixing caudal regions of pelvic bones, fixing members are introduced in particular cases in different directions into recess and suture branches of ischial bones.
