RU70114U1 - DEVICE FOR EXTRACTION OF TISSUES OF PARENCHIMATOUS BODIES AT ENDOVIDE SURGICAL OPERATIONS - Google Patents

Abstract

The utility model relates to medicine, and more particularly to surgery. The purpose of the utility model is to increase convenience, reduce labor intensity and trauma during endovascular surgical extirpation of parenchymal organs (spleen, liver), reduce the time of surgery and, therefore, anesthesia. The device comprises a tubular part, a cutting element made in the form of an impeller located at the end of the tubular working part, a drive and a collector. 1 pf, 2 ill.

Description

The utility model relates to the field of medicine, and more specifically to devices designed for extraction of tissues of parenchymal organs (for example, spleen) during endovascular surgery.

Known surgical device containing a pressure source, a collector, a tubular element and a working nozzle (1).

The disadvantage of this device is the design complexity and inconvenience of use, the inability to remove parenchymal organs (spleen) through endoscopic access due to the inability to grind the organ.

A device for the destruction and extraction of stones from the bile ducts (2).

The disadvantage of this device is the increased invasiveness of its use when removing soft tissues from the abdominal cavity.

A device for necrectomy containing a cutting working part (3) is known.

The disadvantage of this device is the inability to use it for the simultaneous destruction and extirpation of parenchymal organs during endovascular surgery.

Also known is an electromechanical tissue shredder with a tube-knife for endoscopic operations in gynecology, containing a tubular working part, a drive and a cutting element (4).

The disadvantage of this tissue grinder is the inconvenience of its use in the extirpation of parenchymal organs (spleen) from the abdominal cavity during endovascular surgery.

The purpose of creating a utility model is to increase the convenience in the extirpation of parenchymal organs from the abdominal cavity, reducing the duration of surgery and, therefore, anesthesia.

This goal is achieved by the fact that the inner cavity of the tubular working part is connected to a vacuum source, and the cutting element is made in the form of an impeller with pointed edges, fixed inside the working part flush with its working end.

Comparison of the proposed device with others known in the field of medicine, showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material. Figure 1 shows a General view of the proposed device; Figure 2 shows a view along arrow "A" in Figure 1.

A device for extirpation of tissues of parenchymal organs during endovascular surgery contains a tubular working part 1, drive 2. The tubular working part 1 is connected using a flexible tube 3 to a collector 4, which is connected to a vacuum source (not shown in the drawing).

Inside the tubular working part 1 flush with its end 5, the cutting element is made rigidly made in the form of an impeller 6 with pointed edges.

The device is used as follows.

During the endovideo surgery, the removed parenchymal organ (spleen) is mobilized, which is placed intraperitoneally in a plastic bag. The edges of the bag are removed from the abdominal cavity to the front-side wall of the abdomen through one of the laparoscopic approaches. The working end 5 of the tube 1 is introduced into the bag. Drive 2 and a vacuum source are turned on. The tubular working part rotates, while the pointed

the edges of the impeller 6 destroy the parenchymal organ (spleen), and the vacuum captures the crushed tissue and through the tube 3 takes it to the receiver 4.

When the device is operating, the cutting element does not touch the walls of the plastic bag and does not injure it and the surrounding tissues, the possibility of contamination of the destroyed organ tissues in the free abdominal cavity is excluded, and the time of evacuation of the resected organ from the abdominal cavity is significantly reduced.

Thus, the use of the proposed device can improve convenience, reduce complexity, eliminate the possibility of contamination of destroyed organ tissues in the free abdominal cavity, reduce the duration of surgery and anesthesia.

The proposed device can and should be used in the surgical units of medical institutions when performing laparoscopic splenectomies, as well as with endovascular surgical extirpations of other parenchymal organs and their parts (liver, kidney).

The proposed device is simple in design and reliable in operation.
