Description

one

This invention relates to medicine, in particular to cancer treatment of malignant tumors.

There is a method of treating malignant superficial tumors by local anesthesia with novocaine. followed by coagulation of the tumor with a COj laser beam.

However, when using this method, the complete destruction of the tumor site is not achieved and the dissemination of tumor elements into healthy tissues is not excluded.

The aim of the invention is the complete destruction of the tumor site and the prevention of dissemination of tumor elements into healthy tissues.

The goal is achieved by the fact that after anesthesia around the tumor site at a distance of 1.5-2.0 cm from it, a focused CO laser beam cuts through the skin and subcutaneous tissue, and the coagulation of the tumor is carried out with a 1.5-3 laser diameter , 0 mm at-energy illumination of 200-600 W / cm for 1-10 s.

In addition, the skin and subcutaneous tissue cut through the beam of the laser COj with a diameter of up to 1 mm.

The method is carried out

in the following way.

After anesthesia and protection of the surrounding healthy tissues, the laser beam conducts a circular cut of the skin and subcutaneous tissue around the tumor site, 1.5-2.0 cm away from the jero edges. This creates a coagulation shaft around the tumor, preventing dissemination tumor cells in surrounding healthy tissues during the subsequent coagulation of the tumor site itself. Then, the entire area, bordered by this circumference, including the tumor nodule and the surrounding 1 ;; s of its healthy tissue, coagulates the periphery of the periphery to the center. The required coagulation depth depends on the nature of the tumor And the degree of infiltration of the underlying tissues. And is regulated by the exposure of the beam in the coagulation zone.

As a result of coagulation, a tissue defect of a round or oval shape, covered with a brownish, sometimes black, dry film of coagulated necrotic masses, is formed. At the end of the coagulation, the surrounding skin is treated with alcohol and into the wound.

Put on a dry sterile dressing.

The time spent on coagulation of tumor nodules varies from 1 to 10 depending on the size of the tumor nodule. In order to completely destroy the tumor, depending on the type, size, depth, and other features, an energetic ocBeujeHHocTb is required, equal to 200bOr W / cm. With other raffin conditions, the lower the laser output power, the beam should be more focused (1, and vice versa).

i During the first two days, the coagulation film turned into a coco, under which the lightest growth occurs. Crust rejection; with imbibed surface u: uisho (after 2-3 weeks. With large sizes, the coagulated surface (more than 2.5-3.0 cm in diameter) on day 2- 3, the crust, as a rule, rejects, leaving it open; / wound surface. Healing in

In these cases, secondary tension occurs within 1 month.

The proposed method provides the complete destruction of the tumor site and prevents the dissemination of tumor elements in healthy tissue.
