The aim of the invention is to ensure that a bopsin of dense coacinstration of tissues is possible.

The goal is achieved by the fact that the outer tube of the kgpa is equipped with a lance-shaped protrusion located along the cut of the inner tube, at the butt end of the last tube there is a transverse crosspiece with a cutting edge, the cut of the outer and inner tubes is made along the generatrix of the cylinder, and the entire length of the cut of the inner tube is cutting teeth.

FIG. 1 shows a needle for organ biopsy, side view; in fig. 2 - the same view

from above; On part 3 - the working part of the needle ia is a closed position; in fig. 4 shows the working part of the needle in the initial position; in FIG. 5 friendly tube; on (| ig, 6 - inner tube.,

The needle for biopsy of the organ contains an outer pipe & 1 o with a spear-shaped protrusion 2, cut 3 N with cutting edges 4, | aspopo | senimymi along the longitudinal axis of the slice 3 and on the-splitting part 5 of the outer pipe.

An inner tube 6 is inserted into the outer tube 1, the working end of which is made hollow. I T cutting 6 has a cut 7. Cutting teeth are made on the walls of the tube; Tsy 8, located along the entire length of the cut 17, and a knife is mounted on the outer tube; limiter 9 located above cut 3 along its entire length. At the butt end of the inner tube, there is a transverse jumper with an edge 1O, perpendicular to the needle axis.

The needle for organ biopsy works as follows. By the passage of a trumpet 6 relative to the outer tube 1, cut section 3 onto the outer pipe (in this position, a ttrof is inserted in the following, nahfnmer uterus neck, vrokalyva to the prescribed chap; d 6gtg.
