Description

The utility model relates to veterinary surgery and is intended to stop bleeding and close a deep gaping wound during healing.

Known surgical bridge for securing sutures (A.S. SU No. 1066574, publ. 01/15/1984, bull. No. 2) containing a curly plate with end flat sections. Holes are made on the terminal flat sections of the bridge, and pins are installed along the longitudinal axis of the bridge.

Such a device does not provide the possibility of flashing the ligature to the full depth of the wound without visual and tactile control. And the need for manipulation in the wound cavity when flashing the ligature makes it difficult to use it in the field. At the same time, a phased approximation of the edges of the wound is not provided. In addition, the presence of pins along the longitudinal axis of the bridge makes it bulky, towering above the surface of the skin and causing this additional concern to the animal.

Known bracket for rapprochement of the edges of the wound (A.S. SU No. 848001, publ. 07/23/1981, bull. No. 27) containing a housing with needle holders. In this case, one of the holders is installed in the housing with the ability to move towards the other holder and is equipped with a latch. In this case, the housing has a guide for the holder.

The case of such a bracket does not provide regulation of the position of the needles according to the depth of the wound. The casing and retainer of such a device are bulky, they protrude significantly above the surface of the skin and, in this regard, cause additional anxiety to the animal.

A device for rapprochement of the edges of the wound (Patent RU No. 2371117, publ. 10/27/2009), providing full or phased extra focal closure throughout the depth of the gaping wound in the field. It contains surgical needles mounted on jaws that are fixed together by rails and drives of rack-and-pinion drives. Between each pair of drives in a cylindrical shape of the nests there is a transverse beam with the possibility of its rotation relative to the nests. Each pair of drives with a transverse beam mounted on them is rigidly fixed to a support plate provided with an oval hole with the possibility of movement of the support plates towards each other along the rails. Each transverse beam is made in the form of two parallel, connected at the ends of the beams of the sides with a space between them for arranging two branches in it, fan-shaped on a supporting axis mounted in the middle of the transverse beam in the space between the sides that can be fixed in a removable turn signal.

A device for converging the edges of the wound (Patent RU No. 2489990, publ. 08/20/2013, bull. No. 23) is known, in which, in addition to the previous description of the device, a scale is calibrated on the opposite side of the drive plate of each recess, calibrated according to the depth of the spokes in tissues along the angle of rotation of the transverse beam relative to the nest. At the ends of the transverse beam, marks are combined with the drive scale, reflecting the angle of rotation of the transverse beam in cylindrical nests.

The disadvantage of such devices is their bulkiness due to the presence of rails protruding above the skin surface, drives with a transverse beam mounted on them, which are located on the base plate provided with an oval hole.

A device for reducing the edges of the wound (A.S. SU No. 1165376, publ. 07/07/1985), taken as a prototype, containing a ratchet mechanism with a handle and a gear rack with pressure plates, which are prefabricated from separate sections having spikes and holes.

Such a device does not provide adjustment of the position of the spike according to the depth of the wound, since the section spike can be located in the tissue only in vertical and horizontal positions relative to the edge of the wound. The bulkiness of the device is due to the presence of brackets placed in the outer holes of the sections for fixing them after the edges of the wound come closer.

The technical task of the claimed utility model is to simplify the design and reduce its bulkiness.

The technical result of the claimed utility model is to increase the degree of its adaptation to the surface of the animal’s body during simultaneous or phased extra focal closure throughout the entire depth of the gaping wound.

The differences of the claimed utility model from the prototype are:

the presence of rotation marks of the section relative to its longitudinal axis, calibrated according to the depth of insertion of the spike into the tissue of the wound edge; the placement of the spike at the end of the section remote from the wound with the formation of an angle equal to 30 ° -80 ° between the spike and the longitudinal axis of the section; fixing the rail in the axial hole of one of the sections, and free movement of the rail in the axial hole of another section equipped with a stopper; the presence of sites at the ends of both sections.

The technical problem is solved, and the technical result is achieved by the fact that in the known device for rapprochement of the edges of the wound, containing a rail with sections placed on it in a cylindrical shape, having holes, spikes and a locking device, marks on the surfaces of the sections are marked with turning sections relative to the longitudinal axis, calibrated accordingly the depth of insertion of the tenon into the tissue of the wound edge, the tenon is mounted at the end of the section remote from the wound and forms an angle equal to 30 ° -80 ° with the longitudinal axis of the section, the rail is fixedly mounted in verstions of one of the sections, and in the axial hole of the other section, with the possibility of free movement, ensuring rapprochement of the edges of the wound, and the stopper is mounted on the end of the movable section directed to the wound to fix the position of the section relative to the rail, while at the ends of both sections are made platforms for gripping with forceps .

A device for converging the edges of the wound is a rail 1 with sections 2 placed on it in a cylindrical shape (Fig. 1-5). Each section 2 has a fixed spike 3 with a sharp end 4 and an axial hole 5 (Fig. 2). On the surface of each section 2 are marked 6 rotation of section 2 relative to its longitudinal axis, calibrated according to the depth of insertion of the spike 3 into the tissue of the edge 9 of the wound. The spike 3 is installed at the end of section 2 remote from the wound and can be located relative to the longitudinal axis of section 2 at an angle of 30 ° -80 °. The rail 1 is installed motionlessly in the axial hole 5 of one of the sections 2, and in the axial hole 5 of the other section 2 is the possibility of free movement, ensuring the convergence of the edges 9 of the wound. The stopper 7 is installed on the end of the movable section 2 facing the wound to fix the position of section 2 relative to the rail 1. The pads 8, intended for gripping with forceps (not shown in the figures), are made at the ends of both sections 2 (Fig. 3).

The device operates as follows. They clean, degrease and disinfect the skin around the wound according to the generally accepted method. Measure the depth of the wound from the level of the proposed points of insertion of the spikes 3 at the edges 9 to the bottom 10 of the wound. For example, points on the skin are marked with iodine for introducing the spikes 3. To do this, they retreat from the wound by a distance corresponding to the length of section 2, taking into account the length of the edge protruding beyond the edge of the section 2 of the spike 3. The local anesthesia is performed in the marked areas. A sterile device corresponding in size to the depth of the wound is removed from the package, grabbing sections 2 behind the sites 8 with sterile forceps and tweezers. Section 2 is placed on opposite edges 9, respectively, of the width of the wound. The forceps 7 press the stopper 7 to the platform 8 at the end of section 2 and move it relative to the rail 1. Turn sections 2 relative to their longitudinal axis according to the position of the marks 6 calibrated along the depth of the wound. Holding section 2 in the position set according to marks 6, tongs immerse the spike 3 in the tissue of edge 9 of the wound to the set depth. In this manner, a spike 3 is inserted into the tissue of the opposite edge 9 of the wound. Holding the movable section 2 with forceps, pull the rail 1 with tweezers. At the same time, the edges of the wound 9 are brought together. Additional devices are placed on a long wound. After the final approach of the edges 9 of the wound, the end of the lath 1 protruding beyond the edge of the section 2 remote from the wound is shortened.

Examples of specific implementations of a device for converging the edges of a wound.

Example 1. Postoperative closure of the wound of the abdominal wall of the dog, weighing 30 kg. Using a surgical needle, a continuous catgut suture is applied to the peritoneum. The depth of the wound from the level of the proposed points of insertion of the spikes 3 at the edges 9 to the bottom 10 of the wound corresponding to the surface of the peritoneum is 25 mm. For application, a device is used, the spikes of which are directed at an angle of 45 ° to the longitudinal axis of section 2, and the sharp end 4 of the spike 3 is at the level of the end of section 2 facing the wound. Section 2 is 30 mm long. Points on the skin for introducing spikes 3 at a distance of 35 mm from the wound are marked on the skin. Sterile forceps capture sections 2 with a length of 30 mm over the platform 8. Moving the movable section 2 relative to the rack 1, place sections 2 on the opposite edges 9 of the wound, the width of which is 40 mm and the length is 70 mm. Section 2 is rotated relative to their longitudinal axis so that the marks 6 corresponding to 25 mm of the wound depth are at the highest point on the cylindrical surface of section 2 with respect to the skin. While holding section 2 in the position set according to marks 6, pliers immerse the spike 3 in the edge tissue 9 wounds all the way into the surface of the skin of section 2. Similarly, a spike 3 is inserted into the tissue of the opposite edge 9 of the wound. Four devices are placed on the wound with an interval of about 1.0-1.5 cm. Alternately on each device, holding the movable section 2 with forceps, pull the rail 1 with tweezers. At the same time, the edges 9 are brought together until the wound is completely closed. The ends of the rails 1, which protrude beyond the edge of the section 2 remote from the wound, are shortened. Additionally, a protective dressing is applied to the wound.

Example 2 .. The closure of a spontaneous bleeding wound in the withers of a dog weighing 15 kg with a tissue defect with a depth of 20 mm, a width and length of 50 mm. After depilation, the skin around the wound is degreased at 70 ° and disinfected with 5% iodine solution. The wound cavity is washed with a 1% hydrogen peroxide solution. To close the wound, a device is used whose spikes are directed at an angle of 45 ° to the longitudinal axis of section 2, and the sharp end 4 of the spike 3 is at the level of the end of section 2 facing the wound. Section 2 is 25 mm long. Points on the skin for the introduction of spikes 3 are determined at a distance of 30 mm from the wound. In areas marked with iodine, local anesthesia is performed. Sterile forceps grab sections 2 of the site 8. Place sections 2 on opposite edges 9 of the wound. Section 2 is rotated relative to their longitudinal axis so that the marks 6, corresponding to 20 mm of the wound depth, are at the highest point on the cylindrical surface of section 2 relative to the skin. The skin is pierced at the point of insertion of the spike with a perforator 3. Holding section 2 with forceps in the marks 6 position, immerse the spike 3 in the tissue of the edge 9 of the wound until it stops the cylindrical surface of section 2 in the skin. In this manner, a spike 3 is inserted into the tissue of the opposite edge 9 of the wound. Two devices are placed on the wound with an interval of about 1.7 cm. The wound cavity is filled with a sterile hemostatic wipe. Alternately on each device, holding the movable section 2 with forceps, they pull the rail 1 with tweezers. At the same time, the edges 9 are brought together, fixing a napkin in the wound cavity. After stopping the bleeding, forceps are alternately applied to the sites 8 of the movable section 2 of each device. Pressing the stopper 7 to the section 2, move it relative to the rack 1. Having opened the edges of the wound 9, the napkin is removed. Holding the movable section 2 with forceps, pull the rail 1 with tweezers. At the same time, the edges 9 are brought together until it is completely closed.

The ends of the rails 1, which protrude beyond the edge of the section 2 remote from the wound, are shortened. Additionally, a protective dressing is applied to the wound.

Thus, the device has advantages over analogues, simplifying the design and increasing the degree of its adaptation on the animal’s body during the treatment of wounds.
