Abstract

FIELD: surgery. SUBSTANCE: draining channel of washing liquid is located inside supplying channel and has head in the form of funnel with holes on side surface. Draining channel accommodates main clamp with spring-loaded bushing and button. Antiseptic preparation abrasive material is supplied to wound surface through channel which is fastened helical-wise to body outer surface. As a result, efficiency of treatment of purulent wounds by additional necroectomy and withdrawal of foreign bodies is increased. The result is attained by use of abrasive composite material including crystals of drugs, for instance, xymelin. EFFECT: higher efficiency in wound treatment. 2 cl, 2 dwg

Description

 The present invention relates to medicine, namely to surgical devices used to treat wounds.

 One of the many causes of the torpid course of the wound process is necrotic tissue, foreign bodies and tissue sequestration, which, according to our data, make up 11% of the total number of patients with long-term non-healing wounds, trophic ulcers and external fistulas. Foreign bodies also include specially implanted materials, for example, threads when stitching tissues.

 There are various devices for the treatment of purulent-inflammatory wounds / 1, 2 /.

 Closest to the technical nature of the present invention is, taken as a prototype device for the treatment of purulent wounds / 3 /, containing a feed channel for supplying flushing fluid and a discharge channel placed inside the feed and having a tip in the form of a socket with holes on its side surface.

The disadvantages of this device are:
- the inability to use the device for direct extraction of dense foreign tissue, sequestration, located in the depths of the fistula;
- the impossibility of total removal of necrotic tissue;
- low therapeutic reparative-regenerative effectiveness of the administered antiseptic solutions.

 The aim of the present invention is to provide a device that improves the treatment of purulent wounds by additional necrectomy and the extraction of foreign bodies, which is achieved using an abrasive composite material with the inclusion of crystals of drugs, for example xymedon / 4 /.

 The goal is realized due to the fact that a collet clamp with a spring-loaded sleeve and a button is placed in the outlet channel, and a channel is supplied on the outer surface of the housing for supplying repaired and antiseptic abrasive material to the wounded surface, for example, using xymedon crystals.

 By performing a collet clamp with a spring-loaded sleeve and a button in the outlet channel, the possibility of direct extraction of dense necrotic tissues, tissue sequesters and foreign bodies located deep in the fistula is achieved, which significantly increases the effectiveness of the treatment of purulent wounds.

 The execution of a spiral channel on the outer surface of the casing for supplying reparative and antiseptic abrasive material to the wound surface, for example, using xymedon crystals, allows the total removal of necrotic tissues and, as a result, high therapeutic reparative and regenerative effectiveness.

The design and principle of operation of the device for treating wounds are shown in figure 1, 2 graphic materials:
figure 1 is a General view of the device in section;
figure 2 - diagram of the device and the principle of treatment of wounds.

 A device for treating wounds consists of a lower tubular housing 1 and an upper housing 2 interconnected by a threaded connection, in the inner cavity of which a collet clamp 3 is mounted, spring-loaded with a spring 4 with button 5. In the lower housing there is a tube 6 for supplying a washing antiseptic liquid through nozzles 7 into the cavity of the treated wound. The fluid is discharged through the hollow sleeve 8 of the collet clamp 3 and the nozzle 9 connected to the vacuum. The sealing of the inlet and outlet cavities of the washing liquid is carried out by means of a sleeve 10. A channel 13 for supplying abrasive material, for example, xymedon, into the wound cavity is screw-shaped along the outer surface of the housing.

 The device operates as follows (Fig. 1, 2).

 The device is introduced into the cavity of the wound 11 with a rotary movement, after which the tube 6 is connected to a tank with washing liquid, and the nozzle 9 is connected to a vacuum. By means of the fluid entering the wound cavity 11 through the nozzles 7 and its simultaneous suction through the hollow sleeve 8, the wound is washed with the foreign bodies being pulled into the collet 3 (by means of button 5), after which the collet is closed and the foreign body 12 is removed from the wound .

 To cleanse of necrotic tissues, remove foreign bodies and sequesters, crystalline material is fed into the wound through channel 13, through which necrotic tissues are beaten off. As an abrasive (crystalline) material, for example, xymedon - N- (β-hydroxyethyl) -4,6-dimethyldihydropyrimidone-2 - a new pyrimidine derivative approved for industrial production and use in medical practice by order of the Ministry of Health of the Russian Federation N 0287 of 07.12. 93 g. Xymedon is readily soluble in water. When applied topically in the form of 5 - 10% solutions, it has an antibacterial effect, as well as a pronounced wound healing effect. Xymedon does not cause a negative effect on tissues with topical application. The use of crystalline xymedon as an abrasive material is scientifically justified and is unknown in medicine. The synthesis of xymedon is described in / 5 /.

 Example.

 The use of the proposed device in the treatment of patients with purulent wounds has convincingly shown an advantage over traditional methods and devices. We give one of our examples.

 Patient S., 51, was admitted to the surgical clinic on 10.07.96 with extensive subfascial phlegmon of the anterior surface of the left thigh. More than 7 years suffering from diabetes. After short-term preoperative preparation under intravenous multicomponent anesthesia, the patient was opened with an electric knife using an autopsy phlegmon with excision of non-viable tissues. Despite thorough washing of the wound, its bottom remained covered with purulent plaque. Primary suture was not possible. The application of our proposed methodology and device allowed us to achieve intraoperative total removal of devitalized tissues and purulent masses. The bottom of the wound turned pink, slightly bleeding, which created the conditions for the use of a blind seam. Separate interrupted sutures were placed on the main wound with perforated drainage remaining in the cavity. The latter is derived through contraception. Drainage removed on the 7th day. Sutures were removed on the 12th day. Discharged home in satisfactory condition.
