SU1553143A1 - Device for irradiating hollow organs - Google Patents

Abstract

The invention relates to medical devices for treating a disease of the urethra, which makes it possible to increase the uniformity and efficiency of radiation by expanding the folded walls of the urethra due to the fact that the obturator 3 is connected to the ring 4 by means of rods 6. The surface of the obturator facing the ring 4 convex and diffusely reflective, the tube 1 is interposed between the rods. 1 il.

The invention relates to medicine and can be used in urology, in particular in the treatment of diseases of the urethra.

The purpose of the invention is to improve the uniformity and efficiency of irradiation by spreading the folded walls of the urethra

Fig. 1 shows a device for exposing hollow organs, a partial longitudinal section.

The device contains a tube 1, made in the form of a cylindrical tube, the working end of which is cut at an angle of 90 ° to the longitudinal axis, and at the other end fastened together a flange 2 and an obturator 3, made in the form of a cylinder, the diameter of which is larger than the outer diameter of the tube. The tube 4 is movably fitted with a ring 4, equipped with a screw 5, which is connected by rods b with an obturator 3. The end surface of the obturator 3, facing the tube, has a convex shape. On this surface of the obturator and on the inner surface of the tube, a diffraction coating of silicon dioxide with a thickness of 0.6-0.8 mm was deposited. The outer surface of the pipe has the marks 7.

The device works as follows

A tube with an obturator 3 in a closed position is inserted into the urethra to the intended anatomical area. I left the obturator L in a fixed position, and I would mix the tube in the direction of the external oi-urethra for the required distance.

controlled by the marks 7. Rods 6 covering the tube, serve as guides, ensuring movement along the strictly longitudinal axis of the urethra.

By means of the flange 2, a source of ultraviolet radiation is attached to the tube. The light rays reflected from the tube walls irradiate the part of the urethra located between the working end of the tube and the obturator. The part of the light rays that hits the end surface of the obturator, due to its convex shape, is reflected on the walls of the urethra. Radiation dose - 1/2 biodoses (in seconds). The duration of the procedure for one section of the mucous

on average, 30-45 seconds, and the entire affected part, 3-4 minutes.
