Abstract

The device is used to ensure the prevention of inflammatory events in the sites where the spokes are made by pressing napkins with a disinfectant composition. The device comprises a sleeve 1 with a shoulder 2, a spherical recess 3, a longitudinal through groove 4 and a transverse threaded hole 5, a locking screw 6 installed in the aperture 5 and a limiting tube 7 with a longitudinal through slot 8 and a transverse groove 9 under the locking screw 6. Combine the groove 4 and the slot 8 and set on the needle, put a napkin with a disinfectant composition in the recess, press the device to the body, turn the tube 7 to block the groove 4 and fix it to the spoke with a locking screw 6. 4 z. f-ly, 2 ill.

This invention relates to surgery, namely, to surgical instruments.

The compression overlay of the Ilizarov’s distraction apparatus is a surgical procedure that must be performed according to all the rules of surgery, taking into account the need for asepsis, especially when passing the spokes through the bones and soft tissues. Holding the spokes through the tissues and leaving their ends outside without appropriate measures to prevent infections can lead to the development of purulent complications: from minor suppuration of the subcutaneous tissue near the spokes to deep phlegmon and purulent fluxes, as well as osteitis and osteomyelitis.

The known method and device for preventing suppuration at the points where the spokes exit the fabric by closing the points at the entrance and exit of the spokes into the fabric with napkins dipped in alcohol, which are fixed with 5 cm wide strips of bandage and 2 m long, which rolls are placed under the rings. or arc apparatus. At the initial signs of inflammation of soft tissues, ultraviolet irradiation of the skin is carried out; wipes with alcohol are placed near the spokes. Passport is due the next day. With an increase in inflammatory events, soft tissues infect the spokes with broad-spectrum antibiotics that are repeated daily for 3-4 days. If the inflammatory process does not subside, the patient is hospitalized, the needle is removed. A new needle is held after the elimination of inflammation, possibly in a new place.

The known method and device for its implementation often do not prevent the occurrence of suppurations in the places where the spokes pass through the soft tissue and is difficult to control in the places of suppuration, as well as when replacing napkins with new ones. All of these drawbacks lead to a prolongation of the treatment time, the morbidity of all procedures associated with the consequences of the ineffectiveness of using the device.

A device is known for pressing disinfectant wipes to the exit and entry site of the spokes into the fabric, made in the form of plastic discs with peripheral grooves, which are placed on the spokes on a tight fit and press the napkins soaked in them with aseptic substance to the exit point of the spokes.

The disadvantages of these devices are the impossibility of precisely adjusting the pressing force due to the fact that it is difficult to move the tightly-mounted disk on the back, and the impossibility of multiple use of the device, since it cannot be thermally

sanitize, because plastics quickly age at high temperatures.

A metal clip with a screw clamp is known, which is a disk with a slot from the periphery to the center. The side surface of the disk is spherical. Perpendicular to the slot plane, a threaded hole is made in the disk body, into which a rod with a threaded end is screwed. The end of the threaded part of the rod rests on the needle, thereby fixing the disc on the needle. This device allows the wipe soaked in the disinfectant composition to be pressed against the body with any desired force.

The disadvantage of this device is that in the area of the groove the napkin is not pressed against the body. Suppurations are formed in this zone, which leads to an infiltration. Clamping the napkin to the body with a convex sphere leads to squeezing the disinfectant amount of the composition and to the rapid cessation of its action.

The closest in technical essence and effect achieved to the invention is a device for holding a medical dressing with osteosynthesis with a sleeve with undercuts and grooves, a threaded transverse bore and a locking screw installed in the threaded bore, and in the recess an elastic element the form of a spring with a washer.

The disadvantage of the device is that. that it cannot be sterilized during treatment.

The aim of the invention is to simplify the operation of the device due to the possibility of removing the device from the spokes for sterilization during the treatment process.

The goal is achieved due to the fact that the device containing a sleeve with a collar, a recess and a transverse threaded hole in which the locking screw is installed is equipped with a restrictive tube with a longitudinal through slot and a transverse groove for the locking screw, and the sleeve with a shoulder is made with a longitudinal through groove with the possibility of combining it with the slot of the sleeve.

The groove in the sleeve is made in an arc equal to 70 ° and with a width of 0.2 mm larger than the diameter of the screw. The slot in the sleeve is made with a width greater than the diameter of the spokes. The recess is made with a spherical surface and a sphere diameter, different for the diameter of the collar, and the recess depth is 2 mm. The width of the collar is less than half the depth of the hole.

Figure 1 shows the proposed device, the frontal section; Figure 2 is the same, top view.

A device for the prevention of inflammatory events contains a sleeve 1 with a shoulder 2, a spherical recess 3, a longitudinal through groove 4 and a transverse threaded hole 5, a locking screw 6 and a restrictive tube 7 with a longitudinal through slot 8 and a transverse groove 9 under the locking screw 6 installed in the hole 5 The groove 9 in the tube 7 is made in an arc equal to 70 ° and with a width of 0.2 mm greater than the diameter of the screw 6. The groove 4 is made with a width larger than the diameter of the spokes. The recess 3 is made with a sphere diameter equal to the diameter of the collar 2, and the depth of the recess 3 is 2 mm. The width of the collar 2 is less than the depth of the recess 3 twice.

The device is applied as follows.

On the sleeve 1 put on the tube 7, and through its groove 9 screw the screw 6 into the threaded hole 5. Combine the groove 4 of the sleeve 1 with the slot 8 of the tube 7 and put the sleeve 1 on the needle 7. Place between the surface of the body at the exit of the spokes (not shown) and the recess 3 cotton wool or a napkin (not shown) soaked in a disinfectant composition, and press this cotton to the body, rotate the sleeve 1 relative to the tube 7 at an angle ensuring the overlap of the slot 8 with the body of the tube 7 , and fix it with a screw 6 on the sleeve 1 on the needle. Thereby, the disinfecting composition is fixed, which ensures the prevention of infection with the compound 6, unlocks sleeve 1 relative to the spokes, replaces cotton wool with a new one impregnated with disinfectant composition, which is pressed against the wound, and sleeve 1

The use of the device makes it much easier to work with it and allows you to get great benefits in saving time for conducting manipulations to disinfect the places where the spokes exit the patient’s body, and also reduces the consumption of disinfectant materials, 10 F o rmullab and
