Description

The claimed technical solution relates to medical equipment, in particular to surgical equipment, and is intended for drainage of various cavities.

When performing surgical interventions, in some cases there is a need for prolonged drainage of various cavities to evacuate the wound discharge. The drainage lumen is often obstructed by blood clots, necrotic tissues, fatty tissue fragments, the drainage ceases to function, and it must be removed.

Known drainages that are used in clinical practice, are tubes of various lengths and diameters with holes in the end and on the side surface.

For example, a drainage tube with centimeter divisions is known, which is a tube with one spherical closed working end and a side opening [Moroz M.A. Drainage tube with centimeter divisions // Clinical Surgery. - 1969. - No. 5. - S.15].

A disadvantage of the known drainage is the impossibility of cleaning its inner channel without removing drainage from the cavity, which entails the need to remove non-functioning drainage, despite the fact that there is still a need for it.

Known drainage [Bondarchuk O.I., Kadoshchuk T.A. Paired drainage // Surgery. - 1993. - No. 1. - S.58], selected as a prototype, which consists of two elastic tubes connected along a generatrix. On the lateral adjoining sides of the tubes, semi-oval-shaped cutouts are made, which are located one against the other so that they form a through hole opening on both sides of the generatrix. Such a drainage, according to the authors, reduces the possibility of injury to the walls of the cavity with the edges of the holes, since they are located in the recesses between the connected tubes. This, as it were, helps to reduce the inflammatory reaction from the side of the organ to drainage, and, consequently, the release of fibrin, whose films are the main reason for closing the drainage holes and stop their functioning.

The disadvantage of the prototype method, as well as other analogues, is the inability to clean the internal channel without extracting drainage.

The invention solves the problem of ensuring long-term continuous functioning of the drainage due to the created possibility of cleaning the internal channel from blood clots, necrotic tissues, fragments of adipose tissue without extracting it from the drained cavity.

The problem is solved in that in a drainage device made of two paired tubes, a round small hollow container is fixed to the drainage tube, which is connected to a hollow tube by means of a small adapter sleeve, which, in turn, is connected to a large hollow container by means of a large adapter sleeve moreover, at the distal end of the device between the drainage tube and a round small hollow container, a slot is made equal in width and length to the diameter of the drainage tube, at its proximal end, between the drainage a hollow tube and a large hollow container, a slot is made that is equal in width and length to half the diameter of the drainage tube, while a roller is placed inside the large hollow container, which is mounted on a rod passing through the walls of this container, to which a handle is rigidly attached on one side of the outside of the container the rotation of the roller, and on the other side of the rod, a threaded channel is made in it, in which there is a locking screw, and inside the round hollow small container is placed a ball fixed to a thread that is made from a small the hollow container through the distal slot inside the drainage tube in the proximal direction and then through the proximal slot into the large hollow container, where it is entwined around the roller and through the large adapter sleeve, the hollow tube, the small adapter sleeve is led into the small hollow container, where it is attached to the opposite pole of the ball, while the diameter of the ball is made smaller than the inner diameter of the drainage tube. In this case, the drainage tube, a round small hollow container, a small and a large adapter sleeve, a hollow tube are made of elastic material, and a large hollow container is made of a densely elastic material. On the inside of both elastic adapter sleeves, metal sleeves are additionally installed at their junction with the hollow tube. Around the perimeter of both slots, metal plates with rounded edges are rigidly fixed. Fixing plates with three holes are attached to the outer surface of the drainage tube and the hollow tube at the junction of the hollow tube with a large adapter sleeve, and there are three drainage holes on each side of the distal end of the drainage tube. A thread is made on the inner surface of the proximal end of the drainage tube, through which the tube is connected to the hollow connector. There is a groove on the thread pull roller to prevent the thread from slipping. Small and large adapter sleeves, a large hollow container mounted on the drainage tube.

The technical result achieved by the claimed technical solution is that they provide the possibility of long-term functioning of drainage in cavities with a large number of heterogeneous contents, including necrotic tissue, blood clots, fragments of adipose tissue by cleaning the internal channel without extracting drainage from the cavity.

The novelty of the device lies in the fact that the device ensures the continuity of the drainage process and eliminates the need to extract drainage from the cavity due to the fact that the device is equipped with a mechanical device for cleaning the drainage, which is located in a hollow tube, including a ball with a thread, placed in a small hollow container with the possibility of its movement through the distal slot into the channel of the drainage tube with the possibility of moving the ball along it in the proximal direction and back with a thread, the movement of which oh performed by rotating the rotation roller handle. In this case, the mechanism for controlling the movement of the ball is outside the wound channel.

Thus, the set of features of the device allows you to provide the necessary technical result.

The drainage device consists of a drainage tube 1, on the free surface of the distal end of which there are nine oval-shaped drainage holes 2. On the distal end of the drainage tube 1, a round small hollow container 3 is fixed on one side, which is connected to the hollow tube 5 by means of a small adapter sleeve 4, which, in turn, is connected to a large hollow container 7 by means of a large adapter sleeve 6. , a round small hollow container 3, a small 4 and a large 6 adapter sleeves, a hollow tube 5 are made of elastic material, and a large hollow container 7 is made of densely elastic material. In this case, a small hollow container 3, a small 4 and a large 6 adapter sleeves, a hollow tube 5, a large hollow container 7 are fixed to the drainage tube 1. The diameter of the small hollow container 3, the small adapter sleeve 4 and the hollow tube 5 is equal to the diameter of the drainage tube 1. K the outer surface of the drainage tube 1 and the hollow tube 5, at the junction of the hollow tube 5 with a large adapter sleeve 6, fixing plates 8 with three holes in them are attached.

At the distal end of the device between the drainage tube 1 and the round small hollow container 3, a slot 9 is made equal in width and length to the diameter of the drainage tube 1. At the proximal end of the device between the drainage tube 1 and a large hollow container 7, a slot 10 is made that is equal in width and length half the diameter of the drainage tube 1. Inside the large hollow container 7, a roller 11 is placed on which a groove 12 is made to prevent slipping of the thread. The roller 11 is mounted on a rod 13 passing through the walls 14 of a large hollow container. To the rod 13, on one side of the large hollow container, the handle 15 for turning the roller 11 is rigidly attached. The handle is circular in shape. On the other side of the rod 13 there is made a threaded channel 16 with a locking screw 17.

Inside the round small hollow container, a ball 18 is fixed to the thread 19. In this case, the diameter of the ball is made smaller than the inner diameter of the drainage tube. The thread 19 is drawn from a round small hollow container 3 through the distal slot 9 inside the drainage tube 1 in the proximal direction and then through the proximal slot 10 into the large hollow container 7, where it is twisted around the roller 11 and through the large adapter sleeve 6, the hollow tube 5, a small transition the sleeve 4 is held in a round small hollow container 3, where it is attached to the opposite pole of the ball 18. To ensure sliding of the thread from the inside of both elastic adapter sleeves at the point of their connection with the hollow tube Metal bushings 20 are finally installed. Also, to improve the sliding of the thread along the entire perimeter of both slots, metal plates 21 with rounded edges are rigidly fixed.

To ensure the connection of the drainage with other drainage devices, for example, with an aspirator, a thread 22 is made on the inner surface of the proximal end of the drainage tube, by means of which the drainage tube 1 is connected to the hollow connector 23.

The drainage device operates as follows. After the operation is completed, the drainage device is installed in the cavity, which must be drained. When the device is inserted into the cavity, the position of the ball 18 is checked, which should be located in a round small hollow container 3. The device is fixed to the skin with separate sutures, the ligatures of which are passed through the holes 24 in the fixing plates 8. After this, an aseptic dressing is applied.

The outflow 25 of the wound discharge from the cavity 26 is carried out through the hole in the end of the drainage tube 1, through the drainage holes on the distal end of the drainage tube 2. Part of the wound discharge is evacuated through the hole in the end of the round small hollow container 3, from which the wound discharge through the distal slot 9 enters drain pipe 1.

After a certain period of time, which the doctor sets, they perform a change of aseptic dressings, during which blood clots are evacuated from the drainage tube.

To do this, after removing the aseptic dressing, the locking screw 17 is rotated, which makes it possible to rotate the rotation handle of the roller 15. When the rotation handle of the roller 15 is rotated, the thread 19 is displaced to which the ball 18 is fixed. As a result, the ball 18 moves from the round small hollow container 3 through the distal slot 9 into the drainage tube 1. Further rotation of the rotation handle of the roller 15 causes the ball 18 to move in the proximal direction 27. In this case, the ball 18 moves to the proximal slot 10, through which the thread 19 passes into the large hollow container 7. Since the width of the proximal slot 10 is half the diameter of the ball 18, the latter does not pass into the large hollow container 7, but remains in the drainage tube 1. Rotating the handle to rotate the roller 15 in the opposite direction moves the ball in the distal direction 28 and returns the ball 18 to its previous position - in a round small hollow container 3. If there is a blood clot 29 in the lumen of the drainage tube 1, then the ball 18 displaces the 30 clot from the drainage tube 1. Then, the lock screw 17 in the opposite direction than the roller 11 is fixed, thus eliminating the possibility of spontaneous movement of the ball 18 along the drainage.
