Abstract

The invention relates to medical technology, namely to instruments used for puncture and drainage of various cavities. The purpose of the invention is to reduce trauma during puncture and drainage of cavities. The trocar has an external hollow tube 1 with a handle 2 and a sharp oblique cut at the working end. In the pipe 1 are the inner tube 3 and the spring 4. The working end 5 of the tube 3 is made muffled and beveled at an angle equal to the angle of the bevel of the outer tube. On the side surface of the working end 5 of the tube 3 there are several oval holes 6. 6 Il.

Invention to reduce injury to puncture and drainage of cavities.

FIG. 1 shows a trocar incision; in fig. 1 shows section A-A in FIG. one; in fig. 3 section bb in fig. one; in fig. 4 shows a section B-B in FIG. one.

The trocar consists of an outer node of tube 1 with a sharply sharpened 1 m oblique cut on the working shaft, a handle 2, rigidly connected to the non-working end of the outer tube, freely fitting the outer inner tube 3, spring 4, is located inside the handle 2 and connected to the inner tube 3. The working end 5 of the inner 11 of the tube 3 is filled with a stub 11 and gathered at an angle equal to the angle of the outer bevel (.) 1 (tube.

The force of the spring 4 is chosen such that

Iloc. ie, dissecting the wall of the cavity that needs to be drained, the tube 3 under the action of the spring 4 moves forward and enters the punctured floor, the opening 6 is opened on the side surface of the inner tube 3, and liquid begins to flow through it. In this case, the inner tube 3 covers the sharp edges of the working point of the outer tube 1, preventing injury to the opianoB. located in the cavity.
