(54) TROAKAR

one

The invention of the OTIHOCHTCH to medical technology, namely, surgical ilstrumeitis, is intended for drainage.

A trocar containing a stylet and a T | cabin with openings is known in the walls of a working Kyunz, the stylet being installed in a tube with a gap.

However, when a permanent drainage is installed, the TpaeiMHpyeT trocar has soft tissue from the patient.

In order to reduce injuries during permanent drainage installation, the T1roakar tube is made of elastic material with a conical working end, the inner diameter of the tube being made with a stepwise transition to a smaller diameter at the conical end, and the stiletto has an annular abutment located behind the tip.

FIG. 1 shows a trocar with a partial cut; in fig. 2 shows but arrow A in FIG. one.

The trocar includes a tube 1 with holes 2 in the side walls at the working end 3 and a stylet 4 with a handle 5 mounted in the tube 1 with a gap. The tube 1 is made of elastic material with a conical working end 3, and the inner diameter of the tube is made with a stepwise transition to a smaller diameter in the conical tube (nce 3.

Stiletto 4 has an annular dis 6, located aa edge 7.

The trocar is used in the following way. The conical end 3 with tip 7 of the stylet 4 provides for trocar spring in soft tissues. When tube 1 is advanced in soft tissues, the tip 7 and the conical end 3 ensure its corrected, to the necessary

depth, the introduction of the working end of the tube. The presence of holes 2 at the working end of the tube allows one to control its penetration into the cavity, as indicated by the release of fluid (pus) from the distal end of the trocar-drainage tube that runs through the holes 2 and sh, spruce between the stylet 4 and the wall tube.

Trocar can be used for suprapubic simultaneous drainage of the bladder, leaving a constant drainage of the bladder, drainage of the pelvis (nephrotomy), cavernous and adsorbing cavities of the lung and other organs. Application in medical practice of trocars of different diameters will provide drainage of cavities with less trauma, which is of great clinical importance in medical practice, especially in military field surgery.
