Description

The utility model relates to veterinary surgery and is intended to close a deep, gaping wound.

A device for closing the skin is known (US Patent No. 4535772, Fig. 34, publ. 08/20/1985), in which the pins associated with a pair of fasteners, as well as the connecting elements between them in the form of belts with ratchet provide the possibility of multi-stage approach and alignment on one skin surface level at the edges of the wound.

However, when using such a device to bring the edges of a deep gaping wound closer, the risk of postoperative complications due to the presence of protruding parts of the device, as well as the inability to adjust the depth of the wound of the immersion of the pins in the tissue, is not excluded. In the presence of gentle walls of the wound, their uniform alignment is difficult, and flexible belts with ratchet can contribute to the deformation of the edges of the wound during their approach.

A device for converging the edges of the wound (Patent SU No. 2371117, publ. 10/27/2009, bull. No. 30), providing off-site, depth-controlled introduction of knitting needles, multi-stage closure of tissue defect. It contains knitting needles, which are made in the form of curved surgical needles and are mounted on jaws made in the form of plates and fixed between each other by a rail and two drives of a rack-and-screw drive, the drives of which contain a cylindrical shape of a socket. A transverse beam is mounted between each pair of drives in cylindrical sockets. Each pair of drives is mounted on a support plate provided with an oval hole. The transverse beam is made in the form of two parallel, connected at the ends of the beams of the sides with the space between them for horizontal arrangement of two branches in it, fixed fan-shaped on the supporting axis. At the free end of each jaw there is a spoke with a sector of an arc of a circle whose center coincides with the supporting axis, and guides with a spring-loaded lock in the form of a rod with longitudinal faces are made. The cylindrical shape of the nest is provided with an extended part. The extended part contains a corrugated wall. The corrugation has the ability to adhere to the longitudinal faces of the rod. The sides of the transverse beam are fixed in a removable turn signal. The turn signal is made with the capture function in the form of spring-loaded struts with a short axis. A pusher lever is mounted on the axis. The lever has the ability to touch the jaw guides. A protrusion is made on the outer surface of the spring-loaded strut from the side of the removable axis. An extension cord with a probe is fixed on the removable axis to control the depth of immersion of the spokes into the thickness of the biological tissue and a limiter. The limiter has the ability to contact with the protrusion on the outer surface of the spring-loaded strut.

The design of such a device is cumbersome. The risk of tissue damage remains due to the possibility of accidental exposure to the protruding ends of the rigid rails as a lever.

A device for converging the edges of the wound (Patent for utility model No. 161551, publ. 04/27/2016, bull. No. 12), taken as a prototype, providing depth-controlled, off-wound, fractional closure of a tissue defect. The device comprises a rail with sections placed on it in a cylindrical shape and having holes, spikes, and a locking device, on the surfaces of the sections there are marked turning sections of the section relative to the longitudinal axis, calibrated according to the depth of insertion of the spike into the tissue of the wound edge, the spike is mounted at the end of the section remote from the wound and forms with the longitudinal axis of the section, an angle of 30-80 °, the rail is fixedly mounted in the axial hole of one of the sections, and in the axial hole of the other section with the possibility of free movement, providing about rapprochement of the edges of the wound, and the stopper is installed on the end of the movable section facing the wound to fix the position of the section relative to the rail, while at the ends of both sections are made platforms for capture with forceps.

A disadvantage of such a device is also the risk of complications of wound healing due to the presence of a rigid rod protruding beyond the device, which contributes to tissue injury, and the inability to evenly align the walls of the wound.

The technical task of the claimed utility model is to reduce the risk of postoperative complications associated with combining wound walls and preventing the displacement of wound tissues by eliminating the rigid lever formed by the lath.

The technical result of the claimed utility model is to reduce the risk of complications of the healing of the defect by providing the possibility of uniform alignment of the walls along the entire depth of the wound and eliminate the rigid lever.

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

- execution facing the wound of the end of each section in the form of a cone with a flexible rail fixedly mounted on its top, having the ability to move in the hole of another section;

- supplying the holder with a probe located perpendicular to the longitudinal axis of the section and combined with a mark applied in the middle of the section;

- installation on the wedge holder with the possibility of its placement between the stopper and the section.

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 cylindrical shape with grip areas, marks, stopper, holes and spikes, in which the spike is installed at the end remote from the wound section and forms an angle equal to 30-80 ° with the longitudinal axis of the section, the rail is mounted in one of the sections motionless, and in the other section with the possibility of free movement, ensuring rapprochement of the edges of the wound, and the stopper is installed at the end sections for fixing the position of the section relative to the rail, while the end of each section facing the wound is made in the form of a cone with a flexible rail fixed to its top, which can be moved in the hole of another section, and the stopper is aligned with the hole of each section and placed on the opposite side the wound end of the section, equipped with a guide channel for placement of a movable spike in it, while the mark applied in the middle of the section is designed to align with the edge of the wound, the grip area is made in the form recesses with the possibility of their connection with the protrusions of the holder, equipped with a probe located perpendicular to the longitudinal axis of the section and aligned with the mark, while the free end of the probe is located near the location of the sharp end of the stud, introduced, the entire length in the fabric until the stud cap rests in the section, moreover, the guide channel of the section is made coaxially with the combined channel of the holder for moving the spike with the cap in it using a pusher, while the holder is equipped with a wedge placed between the stopper and the section.

rail 1; section 2; spike 3; stopper 4; cone 5; hole 6; guide channel 7; label 8; recess 9; ledge 10; holder 11; probe 12; the sharp end 13 of the spike 3; hat 14; combined channel 15; pusher 16; wedge 17.

A device for converging the edges of the wound is a rail 1 with sections placed on it in a cylindrical shape. The spike 3 is installed at the end of the section 2 remote from the wound and forms an angle equal to 30-80 ° with the longitudinal axis of the section. Rail 1 is installed in one of the sections motionless, and in the other section with the possibility of free movement, ensuring the convergence of the edges of the wound. A stop 4 is installed at the end of section 2 to fix its position relative to the rail 1. The end of each section 2 facing the wound is made in the form of a cone 5 with a flexible rail 1 fixed on its top, which can be moved in the hole 6 of the other section. The stopper 4 is placed on the opposite end of each section 2 from the wound and is aligned with the hole 6 of the section. Each section 2 is provided with a guide channel 7 for accommodating the movable spike 3. Each section 2 is placed on the edge of the wound according to the mark 8, applied in the middle of section 2. The gripping pads are made in the form of recesses 9 with the possibility of their connection with the protrusions 10 of the holder 11 equipped with a probe 12 located perpendicular to the longitudinal axis of section 2 and aligned with the mark 8. The free end of the probe 12 is located near the location of the sharp end 13 of the spike 3, inserted all the way into the fabric until the cap 14 of the spike 3 stops in the section 2. Guide channel L 7 each section 2 is coaxially aligned with a corresponding channel 15 of the holder 11 to move therein stud 3 with a cap 14 by a pusher 16. The holder 11 is provided with a wedge 17 placed between the stopper 4 and the section 2.

The device operates as follows. Two sections are interconnected by flexible rails. To do this, the end of the flexible rail 1 from each section 2 is carried out through the hole 6 and the stopper 4 of the other section. In the guide channels of the 7 sections, spikes 3 are installed with the sharp ends directed towards the fabric 13. Into the recesses 9 of each section, the protrusions 10 of the respective holder 11 are inserted with the wedge 17 between the stop 4 and the section 2, as well as the placement of the spike 3 with the cap 14 in the combined channel 15 of the holder 11. The assembled device is sterilized. Using holders, the device is placed on opposite edges of the wound. Rotating the holders relative to the longitudinal axis of the sections, probes are introduced on both sides of the wound to its bottom. Press the tissue of the wound walls to the probes along their entire length. The location of the wedge 17 between the stopper 4 and section 2 provides the displacement of the sections relative to the rails in both directions. In this case, the wound wall adjacent to the probe 12 assumes a plumb position, and the mark 8 in the middle of section 2 is aligned with the skin along the wound edge. Moving the pusher 16 in the combined channel 15, immerse the spike 3 in the tissue along the edge of the wound until the cap 14 of the spike 3 stops in section 2. In this case, the sharp end 13 of the spike 3 is close in tissues to the free end of the corresponding probe 12 located in the wound cavity. With each section 2, the corresponding holder 11 is removed, removing the protrusions 10 of the holder 11 from the recesses 9 of section 2. Holding with forceps, the ends of the flexible rails are pulled in opposite directions along the long axis of the sections, bringing the wound edges together. The stopper 4, interacting with the flexible rail 1, prevents the divergence of the edges of the wound. As a result of the convergence of the edges of the wound, its sheer walls evenly contact each other. Sections are located on the skin on both sides of the wound at a single level. If necessary, a bandage is applied to the wound area. After wound healing, the device is removed. When this forceps capture the cap 14 of the spike 3 and remove it from the tissues through the guide channel 7 of section 2.

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

Example 1

Mumps at the age of 7 months. In connection with castration, at the stage of closing the laparotomy wound in the right iliac region of the abdominal wall of the animal, a pre-assembled, sterile device was removed from the package for holding the wound edges with the length of the spikes corresponding to the depth of the wound. Sections are placed on opposite edges of the wound. When the holders rotate relative to the longitudinal axis of the sections, the probes are set corresponding to the depth of the wound until the free end of each probe comes into contact with the serous sheet of the peritoneum at the bottom of the wound. By moving the sections, the labels are associated with the skin edge of the wound. At the point of contact of the tissues with the probe, the wound wall acquired a vertical position. The pusher of each holder has a corresponding spike inserted into the fabric. In this case, the sharp end of the spike, being in the thickness of the tissues, is close to the location of the free end of the probe. Holders are separated from sections. Accordingly, two devices are superimposed on the length of the wound. The approach of the edges of the wound was carried out by pulling in the opposite sides of the flexible rails. The edges of the wound are treated with antiseptic ointment. Sections of the device were removed after seven days. In this case, the spikes for the caps are removed with tweezers.

Example 2

Dog weighing 14 kg. After opening and washing the hematoma in the right lumbar region on the edges of the wound, a depth of 1.5 cm has been applied to bring the edges of the wound closer together. Observing the aseptic conditions, a pre-assembled, sterile device with the help of holders is applied to the opposite edges of the wound until the sections come into contact with the skin surface. The probes of each holder are inserted into the wound cavity up to the stop of the free end of the probe in the tissue. In this case, the marks on the middle part of both sections are compared with the skin edge of the wound. The edges on each side of the wound are successively displaced until the wall contacts the probe. Spikes are inserted into the opposite edges of the wound with vertical walls using pushers of each holder until the caps of each spike stop in the corresponding section. In this case, the sharp end of the spike is close in the thickness of the tissues to the free end of the corresponding probe. After removing the holders from the respective sections, the edges of the wound are brought together. For this, the flexible rails of both sections were stretched in opposite directions. After eight days, the device was removed from the surface of the skin. In this case, the spikes for the caps are removed with tweezers.

Thus, the device has advantages over analogues, reducing the risk of complications during wound healing by providing the possibility of uniform alignment of the walls throughout the depth of the wound and eliminating the risk of tissue displacement from the action of a hard lever.
