Abstract

Gastro spiral containing a nitinol structure, characterized by a probe sealed on both sides, with a nitinol wire inside it, and the probe with a wall thickness of 1.0 mm, 5 mm in diameter, 950 mm in length, consists of a thermolabile and pyrogen-free stomach inert to the aggressive environment polyethylene, and nitinol wire with a cross-section of 1.25 mm, length 910 mm with the initially given shape in the form of a spiral, having 2 full turns with a diameter of 130 mm each and a height of 130 mm in a free state, with protective polyethylene worn on its ends tips.

Description

The utility model relates to the field of medicine, namely for the correction of excess body weight.

Currently, a gastric balloon - BIB (Bioenterics Intragastric Ballon - an intragastric balloon by Bioenterics Corporation) is used to correct overweight. It is a smooth ball made of high quality silicone rubber, which is filled with water or air. Its capacity can vary from 400 to 700 ml. (www.smdoctors.ru/ballon bib.php).

But since the size of the balloon is minimized (2.5 * 13.0), it is necessary to carry out iv or endotracheal anesthesia to completely relax the patient in order to mitigate the risk of damage to the oropharynx, esophagus and the balloon itself. Removal of the balloon is also carried out under general anesthesia, as it takes a long time to empty the balloon and remove it. It takes many hours to monitor the patient's condition associated with general anesthesia. It is possible that the balloon inside the stomach is deflated and migrates into the intestine, taking into account the installation (which will require abdominal surgery to remove it) doctor@ms-clinic.ru

The closest in technical essence is the stent - a special elastic metal or nitinol structure made in the form of a cylindrical skeleton, which is placed in the lumen of hollow organs (arteries, veins, esophagus, intestines) and provides an extension of the area narrowed by the pathological process. The stent provides patency of food, body fluids. It is delivered with a delivery device, it is introduced in a sterile form and is intended for single use only. Stent - Wikipedia en.wikipedia.org/wiki/Stentcopy

However, given the size of the stent (maximum up to 2.5 cm in diameter per 10.0-13.0 cm), its design, delivery methods and ways, as well as the average size and volume of the stomach (in a collapsed state, 10.0 cm per 20.0 cm), an imaginary stent of the required size can be installed and removed only intraoperatively.

The task is to use a device that does not require general anesthesia, to eliminate the risk to the life of the patient during its establishment and removal, as well as to eliminate possible complications.

The task is carried out by a hermetically sealed probe on both sides with the nitinol wire inside it of an initially given shape in the form of a spiral.

In FIG. 1 shows a gastro-spiral device, where the probe is 1, with a wall thickness of 1.0 mm, a diameter of 5 mm and a length of 950 mm, consisting of thermolabile and pyrogen-free polyethylene inert to the aggressive environment of the stomach. The probe is hermetically sealed at both ends.

Inside the probe there is a nitinol wire - 2, with a cross-sectional diameter of 1.25 mm and a length of 910 mm of the initially given shape in the form of a spiral having two full turns with a diameter of 130 mm each and a height of 130 mm in a free state. Protective polyethylene tips - 3 are tightly put on the ends of the wire.

Nitinol is a high-tech bioinert material with a memory of a given shape, which is restored at a certain temperature. In this case, at a temperature of 34.0 ° C.

In FIG. 2 shows a fibrogastroscope - 1 with a plastic conductor tube -2 mounted on it with a diameter of 150 mm.

The installation of gastro spiral is as follows.

Under local anesthesia (irrigation of the oropharynx with 10% r-lidocaine solution), the patient is injected with a fibrogastroscope with a plastic conduit pre-worn on it. The assistant fixes the conductor tube and leaves it in the stomach cavity, and the fibrogastroscope is removed. After that, a pre-chilled, unfolded and processed gastro spiral is introduced into the stomach through a conduit tube. The control gastroscopy is also performed through a conductor tube, which is then removed together with a fibrogastroscope.

Gastro-helix removal is performed under local anesthesia. A gastroscopy is performed with the conductor tube previously attached to the fibrogastroscope. An endoscopic instrument, an endoscopic loop, is inserted through the working channel of the fibrogastroscope, which is thrown at the nearest end of the device and, together with the fibrogastroscope, is removed from the cavity of the stomach through a conductor tube. After that, the conductor tube is removed.

The device creates the complete illusion of a full stomach and can be in the stomach for up to a year. It does not interfere with diagnostic gastroscopy if necessary.

The delivery system consists of a conductor tube and can be used once or repeatedly after appropriate disinfection of a high level.

The proposed device, in comparison with existing devices, is significantly different in design features and quality of the material, completely eliminates the risk of damage to the oropharynx, esophagus and stomach, as well as the device itself, which ensures the simplicity and safety of its installation and removal. Excluded device migration.
