RU224371U1 - Simulator for mastering the technique of rumenocentesis in ruminants - Google Patents

Abstract

The utility model relates to veterinary medicine, in particular to surgery, and can be used as a simulator for mastering the technique of rumenocentesis. Many of the existing simulators cannot provide mastery of the technique for performing such an operation. The claimed simulator consists of a plastic box with a hole, 2 valves, a plastic diaphragm with a hole, 2 rubber chambers, a rubber bulb with a valve, a rubber tube, a rubber ring, and a material that imitates animal tissue. The skin is represented by natural animal skin, the subcutaneous tissue is imitated by a foam layer, the muscle layer by a layer of tepofol, the peritoneum by a layer of cellophane film. In addition, the simulator provides for adjusting the air pressure in the rubber chambers using a valve. After the trocar punctures the material simulating animal tissue and the stylet is removed, air begins to gradually escape through the sleeve, simulating the release of gases from the scar when it swells. Used rubber tubes can be easily replaced with new ones.

Description

The utility model relates to veterinary medicine, in particular to surgery, and can be used as a simulator for mastering the technique of rumenocentesis. In case of rumen tympany, as an emergency option for the animal, rumenocentesis or puncture of the rumen is performed to remove the accumulated gas. Many of the existing simulators cannot provide mastery of the technique for performing such an operation.

A surgical simulator is known for applying intestinal sutures and anastomoses, containing a base and fixation devices located on it. In this case, the base is made in the form of a table-tablet, on which two soft intestinal clamps are located, one of which is fixed motionless, and the other with the ability to move along rails, between which several clamp-holders are located on the sides of the table-tablet, and on the side of the movable intestinal clamp, perpendicular to it there is a cylinder for putting on the intestine, which is connected to a pressure gauge through a tube with an air blower located on it (RF Patent for utility model No. 6192, author Sandakov P.Ya. et al., 1998). The disadvantage of this simulator is that it does not simulate the removal of accumulated gas and does not allow performing surgical operations on animals.

A known simulator for mastering the technique of basic surgical skills, which contains a support platform consisting of three parts, one of which contains a reservoir with a silicone pad fixed to the support platform, consisting of three layers simulating the skin, subcutaneous fatty tissue and a layer of muscle fibers, and two triangular-shaped faces made of plexiglass, imitating the edges of a surgical wound, between which silicone rods are stretched, fixed on clamps rigidly attached to the support platform. The other part of the platform contains a reservoir of silicone that simulates the muscle layer. The third part, simulating an artery and vein, is made of two silicone tubes stretched over a support platform and fixed on both sides on blocks rigidly fixed to the platform. At the same time, the silicone layer, which imitates the skin, subcutaneous tissue and muscle fibers, as well as the muscle layer with tendons and nerve fibers, has a color that matches the real one (RF patent for utility model No. 169921, author: Tigai Zh.G. et al., 2017). The disadvantage of this simulator is the complexity of the design and its use only in medical practice.

The objectives of the proposed utility model are: to create a simulator that will improve the quality of training in scar puncture techniques by simulating a real surgical situation that makes it possible for gas to escape from the scar through the trocar sleeve. providing the opportunity for several trainees to perform multiple operations on one simulator. The technical result is achieved by a model of a simulator for mastering the technique of rumenocentesis in ruminants.

The closest in its technical essence is a surgical simulator that has a platform with devices for fixing the intestine, placed in a simulator of the patient’s torso with surgical access to the abdominal organs, characterized in that there are three compartments on the platform: one with an obliquely displaced bottom for the simulator of the intestine , the second - with a device for forming a loop of the intestinal simulator and a container for collecting intestinal contents, made of elastic material and fixed to the walls of the compartment, and the third - with a device for rewinding the intestinal simulator, the lumen of which is filled with an intestinal contents simulator, and has four layers simulating membranes the intestinal wall, and the outer layer passes from the intestine and forms the membranes of the intestinal wall, and the outer layer passes from the intestine and forms a duplicate, simulating the mesentery. However, the device has the significant disadvantage that it is bulky and designed for human use, so our invention is simpler and more reliable.

The claimed simulator consists of a plastic box with a hole, 2 valves, a plastic diaphragm with a hole, 2 rubber chambers, a rubber bulb with a valve, and a rubber tube. On top of the box, a material imitating animal tissue is fixed with a rubber ring. The skin is represented by natural animal skin, the subcutaneous tissue is imitated by a foam rubber layer, the muscle layer by a layer of tepofol, the peritoneum by a layer of cellophane film. In addition, the simulator provides for adjusting the air pressure in the rubber chambers using valves. The drawing shows a simulator for mastering the rumenocentesis technique in general form. 1. Plastic box with a hole; 2. Plug; 3. Plastic diaphragm with hole; 4. material imitating animal tissue; 5. Rubber ring; 6. Valve; 7. Rubber tube; 8. Rubber bulb with valve; 9. Rubber inner tube; 10. Valve; 11. Rubber tube.

The simulator works as follows: rubber chambers are placed in a box connected by a valve passing through the hole in the diaphragm, a material simulating animal tissue is fixed on top of the box with a rubber ring, a rubber tube from a pear is put on the valve connected to the rubber chamber and coming out of the hole in the box. The pumped air enters the rubber chambers and simulates the swelling of the scar. After the trocar punctures the material simulating animal tissue and the stylet is removed, air does not immediately, but gradually escape through the sleeve, simulating the release of gases from the scar when it swells. Used rubber tubes can be easily replaced with new ones.
