RU2642741C1 - Device for single-moment bloodless adenomectomy - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: device contains a tubular drill that is connected by its rear end to an electric drill and is an electro coagulator. Tissues cut with a drill with coagulated masses are sucked through the tube lumen and are delivered through the tap into a reticulated basket with volumetric divisions in the vacuum cylinder, where the completeness of adenomal tissues removal is determined by comparison with the preoperative volume of the adenoma.

EFFECT: minimal damage to the anatomical structures and tissues of the area.

Description

A device for a bloodless simultaneous perineal adenomectomy (Z. Zirova apparatus) contains a hollow tube, the front end of which is turned into an electrocoagulator (Fig. II) by supplying an electric current to the handle (Fig. I-II) with a manual switch connected to the rear end (Fig. .I-VI) with an electric drill, and a side outlet connected to a vacuum pump (Fig. I-III) and to a vacuum cylinder (Fig. IV), in which a mesh basket (Fig. I-IV) is installed with divisions and the volume is measured removed adenomal tissues, while the front end is made in the form of spherical th core drill converted to a coalescer (Fig. I-I), with four windows, in which the separated outwards four counterbored edges for shearing coagulable adenoma tissues, which are sucked through the lumen of the tube a vacuum pump and through the side outlet fall within the mesh basket inside the vacuum container.

Description

In FIG. I shows a complete assembly, where FIG. I-II - handle with switch, FIG. I-I - coagulator electrode, it is a spherical drill.

FIG. I-VI - rear end, used for connection with an electric drill.

FIG. I-IV - mesh basket at the end of the lateral outlet, immersed inside the vacuum cylinder of FIG. I-V, which is connected to the vacuum pump of FIG. I-III.

Areas of use

Parasitic and other cysts of the organs of the chest and abdomen with the removal of contents and coagulation of the walls of the bed, tuberculous cavities in the lungs, their bloodless total removal with full observance of the principle of aparasitism and drainage if necessary, as well as limited purulent cavities of other organs.

A device for a simultaneous bloodless adenomectomy - Z. Zirova’s apparatus

The history of surgical treatment of prostate adenoma has deep roots: so, transvesical adenomectomy, performed in 1886, A.G. Undercut; perineal adenomectomy in 1888, M. Druzhinin. Stokum in 1909 described the technique of the papillary method of adenomectomy. Lidsky A.T. in 1923 he described in detail the technique of the pulmonary adenomectomy in detail. TURP and Da Vinci apparatus are proposed as modern methods of treating prostate adenoma and not only. A more practical and reliable method of perineal adenomectomy was proposed by the surgeon-urologist Z. Zirov, patent No. 2580203 dated 03/14/16.

Analogs of the invention

These include:

1) Transurethral resectoscope;

2) Da Vinci apparatus;

3) Apparatus RU 2339323 C1, 11/27/08, Mulin V.M;

4) A device for simultaneous puncture adenomectomy RU No. 2580203, 03/14/16, Zirov Z.G.

The closest prototype of the claimed invention is a device No. 2580203.

Criticism of analogues

When performing an adenomectomy with existing devices, significant complications are inevitable, such as urethral strictures, infectious complications, urinary retention, fistula of various nature, sexual dysfunction, severe profuse early and late bleeding, requiring repeated operations leading to disability, frequent deaths.

With an adenomectomy, the proposed apparatus No. 2580203 excludes complications such as urethral strictures, fistulas, impaired sexual function, infection of the bed, urinary retention, etc., but it does not have a mechanism for reliable hemostasis.

The advantage of the proposed device is the presence of an electrocoagulator in the device itself, which is able to reliably stop bleeding from the bed of the adenoma during the operation, for which the spherical drill is turned into an electrode by supplying an electric current to a rotating drill with a button for connecting an electric current to the handle of the device.
