Description

The invention relates to the field of medicine, in particular to surgery, and can be used in the treatment of purulent diseases of soft tissues.

The purpose of the invention is the introduction of a curette into a closed cavity.

FIG. 1 shows a curette, general view; in fig. 2 - the same, the hollow curette body; incision; in fig. 3 - the same, with a thin-walled tube installed; in fig. 4 the same, with the established stylet.

The curette consists of a hollow body 1 with a working end having a window 2 with a cutting edge 3 and a connection unit to a vacuum source (not shown). At the end

ten

11x9 cm has several closed pockets, divided by loose partitions, which are destroyed during curettage. When processing evacuated about 160 ml of pus. Through the same curette, the abscess cavity is drained with a TMMK-24 tube. In the ward, the drainage is connected to an aspiration-washing system. Fast normalization of temperature and obliteration of abscess. Drainage was removed after 7 days, was discharged home almost healthy for 8 days after surgery.

Example 2. Sick A., 29 years old, and. b. No. 5042, delivered to the hospital by ambulance with a diagnosis of “post-injection cellulitis of the right annual area, sugar

the working end of the body is coaxial with its cavity, severe diabetes. T yellow form

a hole 4 is made to accommodate the end of the stylet 5 or a drainage tube 6 connected to the body via a bayonet connection 7.

The device works as follows.

Under anesthesia, a small skin incision is carried out into the deep-seated purulent cavity (ab, process, or into the cellulitis zone) using the sharp end of the stylet 5.

diabetes mellitus suffers for about 10 years. Through an incision 1.5 cm long at the border with healthy tissues by the proposed curette, a cavity of a large phlegmon measuring 15x20 cm was processed, and 350 ml of necrotic masses evacuated 20 ml. Through the hollow curette body, a TMMK-24 tube was inserted into the required, most flat area of the abscess and connected in the ward to an aspiration and washing system. The temperaturet, after which the stylet is removed and at, from the tour, normalized from the next day.

a hollow body install a thin-walled tube 6, fixing it on the body. The curette is used to cure the necrotic tissue, and through the hollow body of the curette aspiration is performed.

after operation. Complete obliteration of the purulent cavity, drainage removal and discharge in a practically healthy state 7 days after the operation.

Thus, the proposed curette

scraping masses with simultaneous pro-ZO provides aspiration of closed purulent

washing through a thin-walled tube. At the end of these manipulations, a drainage tube is led through the hollow body of the same curette to the necessary area of the abscess. Example 1. Ill B., 65 years old, and b. No. 5509, delivered by ambulance with a diagnosis of postinjection abscess of the right annual area, psoriasis, nonspecific infectious polyarthritis. Under general anesthesia, a 1.5 cm incision was made at the border of the abscess with healthy tissues. A curette with a stylet inserted into its body was inserted through the incision into the area of the abscess, purulent-necrotic masses were removed by scraping and using an electric suction device.

cavities without collapse of the cavity, irrigation in the process of scraping, as well as drainage of the necessary sites of the abscess, which greatly increases the effectiveness of treatment.

Claims (2)

Invention Formula A curette containing a hollow body with a working end having a window with a Q cutting edge and a connection to a vacuum source, characterized in that, in order to insert the curette into a closed cavity, an opening is made at the end of the working end of the body coaxially with its cavity - not the end of the stylet. ff f / fffjfff / f} f: FIG. g 11x9 cm has several closed pockets, divided by loose partitions, which are destroyed during curettage. When processing evacuated about 160 ml of pus. Through the same curette, the abscess cavity is drained with a TMMK-24 tube. In the ward, the drainage is connected to an aspiration-washing system. Fast normalization of temperature and obliteration of abscess. Drainage was removed after 7 days, was discharged home almost healthy for 8 days after surgery. Example 2. Sick A., 29 years old, and. b. No. 5042, delivered to the hospital by ambulance with a diagnosis of “post-injection cellulitis of the right annual area, sugar diabetes mellitus suffers for about 10 years. Through an incision 1.5 cm long at the border with healthy tissues of the proposed curette, the cavity of a large cellulitis 15x20 cm was treated, 350 ml of necrotic masses were evacuated. Through the hollow curette body, a TMMK-24 tube was inserted into the required, most flat area of the abscess and connected in the ward to an aspiration and washing system. The temperature returned to normal from the next day. Tff- after operation. Complete obliteration of the purulent cavity, drainage removal and discharge in a practically healthy state 7 days after the operation. Thus, the proposed curette cavities without collapse of the cavity, irrigation in the process of scraping, as well as drainage of the necessary sites of the abscess, which greatly increases the effectiveness of treatment. Invention Formula A curette containing a hollow body with a working end having a window with a cutting edge and a connection unit to a vacuum source, characterized in that, in order to insert the curette into a closed cavity, an opening is made at the end of the working end of the body coaxially with its cavity no end of the stylet.
