The invention relates to medicine, namely to devices for biopsy of organs, and is an improvement of the device according to the author. № 1050696

The purpose of the invention is to provide control of a predetermined size of the needle plug.

Figure 1 shows a device for a biopsy of the kidney, a general view; figure 2 - section aa in figure 1.

The device contains a pointed hollow needle 1 in which channel 2 is made. In needle 1, a stylet 3 is installed with a handle 4 and with a longitudinal section 5 of the working part having cutting edgesHHbie edges 6. The device has a removable sleeve (not shown) mounted on the stylet 3, allowing it to exit from the needle 1 to a strictly defined length. If it is necessary to increase the output of the stylet 3 from the needle 1, for example, when the needle is reground, the sleeve may be replaced by another. The needle 1 has a handle 7, the channel 2 within the handle is equal to the diameter of the sleeve. The device is provided with a housing 8, an adjustable length adjustable, with a guide groove 9 for the needle 1 and a movably mounted handle 10 with a latch 11 for the finger. On the housing 8 there is a scale 12 and fixing screws 13.

The operation of the device is as follows.

First, anesthesia is applied in layers. A skin and fiber incision is made along the UE rib. The finger stupidly stretches the muscles, after which

palpation of the lower pole of the kidney. Then a latch 11 is put on the index finger, and the rest of the fingers are placed on the handle 10. In this position, the device is inserted into the point with the index finger with the needle 1 immersed in it. The handle 4 advances the Stiletto 3 until it stops. At the same time, the cut end of the stylet 3 diverges and

immersed in the renal tissue at a predetermined depth. Using the sleeve, the needle 1 is wiggled on the stylet 3. The cut end of the stylet 3 converges and plucks a sample of the renal tissue, after

which device is removed from the kidney. Before the biopsy, the device is sterilized and assembled, which is in accordance with the fact that the device is fixed in the housing 8,

wherein the stylet 3 is inserted into the needle 1 and the guide groove 9 until the ends are aligned. When the stiletto 3 and the needle 1 are regrinding, the length of the body 8 is reduced by means of a scale 1 2 and fixing screws 13 by the amount of a regrinding which is constant and equal to thirteen renal cubes.
