Description

k

fPuzJ

This invention relates to medicine, in particular to devices for removing tumors from tubular organs.

The aim of the invention is to reduce the trauma during the circular excision of the tissues on the inner walls of the internal organs and to account for the possibility of visual inspection through a bronchoscope.

Fig. 1 shows an endoscopic knife with triangular teeth, a general view; figure 2 - endoscopic knife with a curved cutting edge.

The knife consists of a tube 1 with an emphasis

2i figured cutting edge located at an angle to the axis and made in the form of miscellaneous teeth

3c with a cutting edge on the long side 4 or in the form of a curvilinear helix 5 with a protrusion 6.

The knife is used as follows.

The knife is put on the bronchospace tube. Cutting knife edge in the original

The position is located 2-3 mm above the distal end of the bronchoscope tube. The diameter of the tube of the bronchoscope and the diameter of the knife are selected depending on the diameter of the trachea or bronchi of the patient.

Before cutting the growths, the knife is thrust forward, the depth of the knife in tissue growths is regulated by the stop 2. By turning the bronchoscope with the knife extended with the help of stop 2 clockwise and pushing it forward, the cicatricial growths are cut off with the cutting edge. The stop 2 in this case allows control of the centering of the knife in the lumen of the hollow organ.

Change of standard tubes with worn knives on them consistently

the increasing diameter allows for layer-by-layer cutting of tissue, thereby increasing the lumen of hollow organs to the required size. Through the inner tube of the bronchoscope, blood, clots and sheared tissues are aspirated.
