Description

 The invention relates to veterinary medicine and can be used to amputate a tail with skin folds while suturing a wound or amputating other tissues or organs.

 Known methods for trimming the tails of lambs, the main methods of which are circular dissection of the skin, soft tissues and caudal vertebrae.

 Various methods are used to stop bleeding and prevent infection of the surgical wound, such as cauterization, applying Zanda forceps, applying a special elastic ring, a device for trimming the tail while burning it.

 These methods according to the observation of the authors have several disadvantages, the main of which are the complexity and duration of the manipulations, the presence of bleeding, frequent complications, slow healing of the wound.

 In Australia, Mul operation is widely used, i.e. removal of sub-caudal skin folds with high tail amputation for the prevention of wolfarthiosis. At the same time, amputation of the tail and skin folds is performed with scissors, leaving the wound gaping, followed by healing by secondary intention. This operation can be performed on strong lambs and provided there is no insect summer and in a dry climate, as it gives significant complications.

 Classical veterinary surgery recommends an amputation method and a device for tail amputation in lambs with ligatures (threads) applied to the skin and subcutaneous tissue of the root of the tail, followed by cutting the tail through the joint between the 3rd and 4th caudal vertebrae, after which the stitched threads are closed and the wound is closed with skin (see Reshetnyak V.S. Veterinary Medicine, 1978, N 2, p. 81). The method gives satisfactory results, but it is difficult to perform, as it consists of three stages: cutting off the tail, stopping bleeding by ligation of blood vessels and connecting tissues by suturing.

 Known combination forceps for removing cellular tissue from the body cavity, consisting of cutting blades attached to one end by a flexible tube that are opened and closed by a pushing or, accordingly, pulling movement of the wire rod. These blades have respective inner surfaces acting so as to act as scissors, and corresponding external surfaces. There is a device for clamping cut off cellular tissues, containing at least one clamping element that protrudes from the back side of one of the blades and the lever system moves towards the other blade, adjacent to its outer surface and clamping the cellular tissue, cut off by scissors, between the specified lever element and outer surface of the second blade.

 The proposed device allows you to cut off the tissue and remove them without simultaneous suturing.

 The purpose of the invention is to increase the efficiency of the use of a device that reduces tissue injury during suturing, and to increase its quality with improved wound healing.

 Figure 1 shows a device for cutting off tissues and organs (histo-organotom), a General view; figure 2 rocker mechanism; figure 3 gear mechanism; figure 4 lever device; figure 5 loop guide.

 The device contains two branches 1 and 2, consisting of an oval-shaped cutting-3 part 3 and a handle 4, in which there is a hole 5 for a bolt 6. The branch 2 has a handle 7 and a cutting-torsion part 8, consisting of a parallel cutting 9 and a torso 10 plates, between which there is a cutting-torsion part 3 of branch 1, adjacent to the corresponding sides of the plates 9 and 10 of branch 2.

 A guide rail 11 with a groove in the form of a wings 12 and fixing bolts 13 is perpendicularly located on the torsion plate 10 in front of the hole 5. Angular rail 14 is also fixed to the rail 11 with the wings 12 and also with a groove in the form of the wings 15. There are vertical holes 17 in the perpendicular plate 16, in which the needles 18 are inserted, fixed by bolts 20. A gear 21 with a handle 22 is attached to the bolt 6. The handle 22 may correspond to the handle 7 (Fig. 1) or be shortened 23 (Fig. 3) with a ratchet 24 mounted on an axis 25 with a spring 26.

 The vertical movement of the plate can also provide a linkage mechanism (Fig. 4). The angle rail 27 has a groove in the form of a link 28 that moves along the guide of the rectangular sleeve 29 secured by a bolt 6. In this embodiment, the guide rail 11 is excluded. The handle 30 is pivotally fixed to the branch 2 and to the angle rail 27 by a bolt 31 through an elongated hole 32.

 Separately, there is a loop guide (Fig. 5) having a handle 33 and a needle 34, at the opposite end of which there is an oval eye 35. A capsule 36 is placed in the hollow handle 33, into which is placed a spool 37 with a thread 38 wound on it and threaded into a grooved nipple 39 .

 The device operates as follows. The operation is performed in compliance with the rules of asepsis and antiseptics. The whole device is cold sterilized (ayatin). The tissue or part of the organ to be amputated is pulled and inserted into the cutting-torsion device, parts 3 and 8 are cut off by the handles 4 and 7. After cutting off the tissue, the torus plate 10 and the torse surface of part 3 squeeze and hold the edges of the tissue. The height of the needles and their number are set depending on the size of the cut-off fabric. At this time, the thread 19 (Fig. 2) is removed from the ears of the needles 19, and a loop guide with a thread 38 is inserted into the loops formed, the end of which is fixed with tweezers or a needle holder, and the loop guide needle 34 is removed and the thread 38 is cut. Then, the plate 16 is displaced (Fig. 2). 1) and the free ends of the threads 19, 38 (figure 5) are pulled together, the result is a shuttle seam.

 After suturing, the wound is treated with the prescribed medicinal products. When using absorbable suture material, the sutures are not removed, and when using non-absorbable material, the threads are removed after 8-10 days by trimming the side assembly and removing the threads 37.

 In contrast to the prototype, the proposed device allows simultaneous cutting off, tissue torsion and the application of a shuttle seam that connects the wound in the tissue cut-off area and simultaneously stops bleeding.

 In the patent and scientific literature available to us, no design of devices for simultaneous cutting off of tissues and organs and suturing similar to the one proposed has been revealed.

 The use of a device for cutting off tissues and organs (histo-organotom) will reduce the time to perform operations and provide a better connection of the edges of the surgical wound.
