Description

Multifunctional Gastrointestinal Probe

The utility model relates to medicine, in particular, to the diagnosis and treatment of the syndrome of functional insufficiency of the gastrointestinal tract in surgical diseases.

Currently, in most cases, it is customary to intubate the gastrointestinal tract during surgical operations, since any pathology and even laparotomy creates conditions for functional and organic insufficiency of the gastrointestinal tract. The intubation of the gastrointestinal tract according to Abbott - Miller is still known and popular. Moreover, in this case, the very design of the probe is very important, since the efficiency of the gastrointestinal tract depends on this. Moreover, at the present time, these probes, in addition to the therapeutic purpose, are used as a diagnostic one in order to prevent various surgical complications.

Various types of probes and bowel intubation methods are known. With intubation, as a rule, many surgeons use an endotracheal tube for decompression of the stomach and small intestine. This is a multi-hole probe installed transnasally, proposed by Miller, Abbot 1934 (Yu. M. Dederer, “Pathogenesis and treatment of acute bowel obstruction 1971, pp. 178 - 179), two-lumen probes A.P. Oleksa 1957 (Yu. M. Dederer "Pathogenesis and treatment of acute bowel obstruction 1971, p. 178 - 179)

These probes are standard, easy to use, but have several disadvantages; cannot be used to diagnose intracavitary pressure, to predict the course of the pathological process, it is difficult to conduct enteral nutrition in the early postoperative period, there is a large loss of electrolytes and these probes are very traumatic.

To better advance the probe in the aboral direction, the authors of Wild (1944), Harris (1945), Cantor (1947) (Yu. M. Dederer “Pathogenesis and treatment of acute intestinal obstruction 1971, from 177 - 191) developed a mercury tip. The disadvantage of the latter is the limited use due to the possible leakage of mercury from bags filled with mercury. Safer probe designs by V.G. Gerasimenko, V.A. Shaprinsky, (1994) (V. G. Gerasimenko, V. A. Shaprinsky, “Intestinal probe 1994 (RU 2025140, 12/30/94), where the guide and working parts of the probe are made in the form of a cone. Polyfunctional probes for simultaneous lavage have gained the greatest popularity inside the intestine, decompression and enteral nutrition. A probe consisting of two tubes for the treatment of colon wounds (RV Senyutovich, “Probe 1995 (RU 2029570, 02.27.00), two-channel probe (N. A. Karasev, L.U. Shramko, “Gastrointestinal probe 1997 (RU 2074743, 03/10/97) and a three-channel probe (Yu.M. Maksimov, V. A. Zolkin, V. M. Spindler gastrointestinal probe 2000 (RU 2152807, 07/20/00)

In order to reduce the time of the probe, a probe was proposed (R.V.Senyutovich, O.V. Tkach “Probe 1994 (RU 2022569, 11/15/94), consisting of two tubes of a larger (15 mm) and smaller (3 mm) diameter at the end of which There is a thickening. After the probe, the tube of larger diameter is removed and a 3 mm tube remains for decompression. However, adequate drainage of the intestinal discharge does not occur, since the 3 mm tube has capillarity properties and cannot provide adequate decompression.

The main disadvantage of this probe is the impossibility of its use for the diagnosis of intracavitary pressure to predict the course of the pathological process and for electrical stimulation for therapeutic purposes.

The closest in design to our utility model is the probe (Yu.M. Maksimov, V.A. Zolkin, V.M. Shpindler “Gastrointestinal probe 2000 (RU 2152807, 07.20.00), which is a tube in the cavity of which there is a longitudinal

a diametrical partition that forms two channels: suction, made by side holes; evacuation and third channel having an outlet for supplying nutrient or flushing solutions.

There is a tip at the insertion end of this tube. A transverse sealed partition is installed inside the tube cavity to prevent the solution from entering the hole of the suction channel when the probe is in static position.

This probe can be used for nutritional function, flushing, decompression. The disadvantages of this probe are the inability to measure intracavitary pressure and therapeutic electrical stimulation, this probe makes nasal breathing difficult, in addition, it has a structure difficult to manufacture.

The utility model proposed by us solves the problem of the multifunctionality of the used probe for the purpose of diagnosis and treatment. The essence of the utility model is shown in drawings 1 and 2. Figure 1 shows the design of the probe itself. Figure 2 shows the installation of this probe into the gastrointestinal tract.

1- intubation probe installed throughout the esophagus

2- intubation probe installed at the level of the stomach and small intestine

3- olive for holding the probe inside the intestines

4- thin probe for carrying out enterolavage, enteral nutrition, measurement

intraluminal pressure

5- terminals for electrical stimulation

6- electrical wires for electrical stimulation

The proposed probe (1) is a hollow structure with a diameter of 7 mm, which expands through 70 cm to 14 mm (2). At the expansion boundary there are two holes with a diameter of 4 mm where a probe (4) with a diameter of 3 mm is installed. This probe passes inside the cavity

large tube and extends to the distal end. The length of the thickest probe (2) is about 3 meters; there are holes with a diameter of 3 mm on it, spaced 3 cm apart. The holes begin retreating from the proximal end of 70cm. At a distance of 1 meter from the distal end, there are two ring electrodes (5) with an interelectrode distance of 10 cm, from which multicore insulated wires (6) extend to the electric stimulator.

The probe is installed transnasally so that the first opening and the expansion itself are in the stomach. The surgeon gropes for the probe with his left hand and further intubation is carried out by phased corrugation of the loops of the thin intestine and stringing them on the probe. The proposed probe can be used to solve various functional problems, in particular for measuring the total pressure in the cavity of the gastrointestinal tract and in individual segments of the small intestine. The probe does not impede nasal breathing and can be used as a framework for applying anastomoses, for adhesions of the gastrointestinal tract, for drainage of the intestine in the first phase of inflammation, for enteral nutrition, for correction of intestinal homeostasis and after the first phase of inflammation subsides to introduce energy products to maintain metabolic balance of the patient’s body and electrical stimulation.

Thus, the proposed probe can reduce bed days, reducing the cost of maintaining surgical patients in a hospital.
