Abstract

To prevent traumatizing the cellular and intercellular structures of the biopsy specimen, the capsule contains body I in the form of a hollow cylinder, the end of which has a fitting 2 for connection to a vacuum source. On the side wall of the housing 1 there is an aspiration hole 3 with a cutting edge. The other end of the capsule is made in the form of a lid 4, which has an axial bore 5 and is connected to the housing 1 by means of a detachable connection. Inside the housing is movably cylindrical knife 6 in the form of a glass with a cutting edge. The knife 6 has an emphasis 7 eccentrically located from its axis. The lid is made of magnetically soft material, and the knife is made of magnetically hard material or the lid is made of magnetically hard material and the knife is made of magnetically soft material, the body is made of nonmagnetic material. 1 il.

Description

The invention relates to devices used in medicine for collecting bioptate from hollow organs.

The aim of the invention is the prevention of trauma to the cellular and intercellular structures of the biopsy.

The capsule for biopsy is shown schematically in the drawing.

It consists of a housing 1 in the form of a canopy on a cylinder, the end of which has a fitting 2.

the shell of the test organ through the aspiration hole 3 inside the capsule, and when the pressure inside the capsule is lowered to 290-300 mm Hg. Art. the cylindrical knife moves away from the lid, with acceleration moves along the axis of the capsule, the compartment of the mucous membrane. The stop 7 stops the movement of the cylindrical knife, prevents the contact of its cutting edge with the end part of the capsule.

On the side wall of the housing 1, an ac-u is made. After the biopsy is collected, a capsule for the biopsy hole 3 is removed from the organ from the cutting edge. The biopsy is processed and examined.

Capsule for biopsy can be used both in the hospital and in the clinic. Its application provides what kind of. The other end of the capsule is made in the form of a lid 4 having an axial hole 5 and connected to the housing 1 by means of a detachable connection. Inside the housing is movably cylindrical knife 6 in the form of a glass with a cutting edge. The cylindrical knife has an emphasis 7 eccentrically located from its axis.

The cover is made of a magnet of a soft material, and the knife is made of a magnetically hard material or the cover is made of a magnetically hard material, and the knife is made of a magnet of a soft material; the casing is made of a nonmagnetic material.

The biopsy capsule works as follows.

By biopsy sampling, it is connected to a tube (not shown) using a choke and is inserted into a hollow organ, such as the stomach. In this case, the cylindrical knife 6 is held in its extreme position, in contact with the lid 4. Then the other end of the tube is connected to the vacuum unit and a vacuum of 250-280 mm Hg is created in the cavity of the capsule. Art. At the same time, the mucous membrane engulfs

 biopsy specimens without trauma to biopsy structures.
