Description

The invention relates to medicine and can be used in the development of devices for autonomous endoscopic sounding of the gastrointestinal tract.

A device for sensing the gastrointestinal tract (GIT) with an immobilizer is known (US patent No. 7946979, publ. 05.24.2011).

The specified device comprises a capsule-shaped housing in which a power source, measurement sensors such as thermometers, pH meters, optical scanners, image sensors, an information recording and transmission module, an immobilizer, a processor for controlling the immobilizer are located. The device can be used for gentle monitoring of the gastrointestinal tract as a whole, as well as for a detailed examination of individual sections of the gastrointestinal tract, for example, for monitoring after surgery. To conduct continuous sensing of individual sections, the device is fixed in the studied area of the gastrointestinal tract. For fixing on the walls of the gastrointestinal tract, the device contains an immobilizer, which is an ejected anchor made in the form of a rod, the outer end of which is pointed or made in the form of a hook for engagement with the intestinal wall. The release of the anchor is carried out by the processor signal. When a signal is supplied from the processor, the element that holds the spring in a compressed state is destroyed, and the anchor is removed outside the capsule body and fixed on the wall of the gastrointestinal tract. In a fixed position, the device carries out continuous detailed sounding of the studied section of the gastrointestinal tract. After a certain time period has elapsed, the anchors made of material that is destroyed in the gastrointestinal tract are destroyed, and the sensing device continues to move under the action of peristalsis.

The disadvantage of this device is the possibility of only passive advancement of the capsule along the gastrointestinal tract under the action of peristalsis, as well as the impossibility of advancing the device along the gastrointestinal tract in the direction opposite to the movement under the action of peristalsis.

A device is known - a video capsule "Mermaid" (Biobyte, 07/03/2011 http://biobyte.ru/videocapsula-mermaid/ - prototype), in the casing of which a power source, a light source, a video camera, a video processing and transmission unit are installed. The capsule is equipped with a mover fixed at one end of the capsule and made in the form of a tail fin, which is equipped with a magnetic control mechanism that allows you to control the direction and location of the capsule in the intestine. The movement of the device can be adjusted with the joystick from an external control panel.

The disadvantage of this device is a significant increase in the length of the video capsule due to the installation of a mover-fin.

A controlled microcapsule-type controlled robot endoscope is known for the active movement of the sounding video capsule along the gastrointestinal tract and containing a body in the form of a body of revolution, inside of which there is an oscillating inertial mechanism that creates a cyclic alternating inertia along the longitudinal axis of the body to move forward and backward (WO 2007128084 A3, 11/15/2007), D1 - prototype.

The main disadvantages are the complexity of the design of the inertial mechanism, significant dimensions and weight.

The task of the medical equipment in this area, the solution of which is the proposed technical solution, is to eliminate these drawbacks and simplify the design of the inertial mechanism.

The solution to this problem is achieved by the fact that in the proposed module for the active movement of the sounding video capsule along the gastrointestinal tract, comprising a body made in the form of a body of revolution, inside which an oscillating inertial mechanism is installed, creating a cyclic alternating inertia force along the longitudinal axis of the body, according to the invention, oscillatory the inertial mechanism is made in the form of an eccentric driven by an electric drive, the specified eccentric mounted on the shaft of the electric drive, When this portion of the outer surface of the body casing made structural elements that create a resistance force directed along the longitudinal axis of the housing, with different motion module back and forth through the gastrointestinal tract.

In an embodiment, the module comprises a controller connected to a drive of an oscillatory inertial mechanism.

In an embodiment, forming the outer surface of the module housing is made in the form of a helical comb.

The targeted movement of the capsule using the active displacement module is carried out by creating a driving force - the resulting forces acting in one oscillation cycle of the inertial mechanism: alternating inertial momentum forward and backward, directed along the longitudinal axis of the module, equal in magnitude in the forward and reverse direction, created by the oscillatory inertial mechanism, and the resistance force arising from the interaction of structural elements made on the outer surface of the mod A shape and arrangement of which determine the minimal resistance during forward movement of the module than in the reverse direction, with a support / GIT surface.

The technical result achieved by the claimed invention is to simplify the design of the inertial mechanism of a small-sized device for actively moving a video capsule for sounding along the gastrointestinal tract.

The invention is illustrated by drawings, where in FIG. 1 shows a general view of a gastrointestinal sensing video capsule with an active displacement module; FIG. 2 shows a diagram of an active displacement module, FIG. 3 shows a diagram of a movement module as part of a video capsule; FIG. 4 is a diagram explaining the principle of movement along the gastrointestinal tract of a video capsule with an active movement module.

The module 1 for the active movement of the sensing video capsule along the gastrointestinal tract, including a power source, a light source, an information recording and transmission module, gastrointestinal tract sensors, contains a body 2 made in the form of a body of revolution, inside of which an oscillating inertial mechanism 3 is placed, including an eccentric 4, mounted on the shaft of the electric drive 5, connected to the controller 6. On the outer surface of the housing 2 made structural elements 7, the shape and location of which create different resistance Phenomenon when moving the module case forward and backward.

The proposed module for the active movement of the sensing video capsule along the gastrointestinal tract works as follows.

The module for the active movement of the sensing video capsule along the gastrointestinal tract 1 (hereinafter - the module) is connected to the video capsule so that their longitudinal axes are parallel. Then the video capsule is inserted into the esophagus, orienting the movement module with the side with less resistance to movement opposite to the direction of movement under the action of peristalsis. Next, the video capsule moves along the gastrointestinal tract in a passive mode under the action of peristalsis. If necessary, a detailed examination of the gastrointestinal tract, passed in passive mode, the module with the video capsule is moved back to the required distance using the active movement mode. To move the video capsule along the gastrointestinal tract in active mode, the controller 6 gives a command to turn on the electric drive 5 of the inertial inertial mechanism 3, which creates oscillatory movements of the housing of the displacement module and, therefore, the video capsule as a whole along the longitudinal axis, at the same time, due to structural elements 7 made on the outer surface of the housing 2 of the active displacement module 1, provide different resistance when the video capsule moves in opposite directions, as a result of the resultant yl videocapsule resistance and inertia moves toward the movement with less resistance.

In an application, the active movement module 1 as part of the video capsule is inserted into the esophagus with the side with less resistance to movement in the direction of movement under the action of peristalsis. The oscillatory inertial mechanism 3 is activated, and the video capsule in the active mode moves along the gastrointestinal tract, under the action of the forces described above. If the measured parameters of the gastrointestinal tract correspond to the control values entered before use, the controller 6 turns off the oscillatory inertial mechanism 3. The video capsule in the passive mode of movement moves under the action of peristalsis at a lower speed, making detailed sounding of the gastrointestinal tract. Upon completion of the plot, characterized by altered conditions of the gastrointestinal tract, the controller 6, based on the analysis of the gastrointestinal tract status, gives a command to turn on the electric drive 5, the active movement module 1 is activated, the speed of the video capsule moving along the gastrointestinal tract is increased.

In an application, the active movement module 1 as part of the video capsule is inserted into the rectum and moved in the active movement mode to the selected examination site, then the active movement module 1 is turned off. The video capsule in the passive mode moves under the action of peristalsis, probing the selected area. If necessary, the active movement module 1 is activated again.

The illustrations and description of the features of the invention do not cover the entire spectrum of possible modifications and equivalent changes that are obvious to a person skilled in this field. It should be understood that the appended claims cover all possible modifications and changes that fall within the spirit of the present invention.

Using the proposed technical solution will allow you to create a module for the active movement of the sounding video capsule along the gastrointestinal tract, which allows you to adjust the speed of the video capsule moving along the gastrointestinal tract, including by measuring the parameters of the gastrointestinal tract, thereby optimizing the amount of information recorded by the video capsule on the gastrointestinal tract, increasing efficiency sensing process, as well as reduce the time of research.
