Abstract: FIELD: medical technology.  
     SUBSTANCE: group of inventions relates to medical technology, namely to physiotherapy devices, more precisely to a girth-adjustable device for expanding and stretching the hole of the body. In accordance with the first embodiment, a device with an adjustable girth for expanding and stretching the body hole includes: a. at least one control device having a first end and a second end; b. at least one threaded shaft having a first end, an intermediate section, a second end and a longitudinal axis; c. a case having the first end of the control device, the second end of the shaft element with a set of grooves of the shaft elements and with a set of protrusions of the shaft elements, as well as a non-threaded channel; d. at least one module having at least one conical part with an inclined height, at least one counter-rotating connection and a channel, and a threaded shaft is installed in the above channel; e. a set of shaft elements having a first end, at least one case groove, an intermediate section, at least one module cavity with an inclined edge, at least one module connection groove and a tip, and f. at least one shell having a first end, an intermediate section, a tip and a shell girth. The first end of the above-mentioned threaded shaft is connected to the second end of the above-mentioned control device. The above-mentioned first end of the above-mentioned threaded shaft is installed in a non-threaded channel, and at least the second end of the above-mentioned control device and the first end of the above-mentioned threaded shaft are placed in the case. At least one counter-rotating compound is selected from a group that includes a linear counter-rotating compound, a counter-rotating compound in the form of a capital letter T, and a counter-rotating compound in the form of an oblique capital letter T. The channel is selected from a group that includes a non-threaded channel, a threaded channel, a threaded channel having at least one mounting cavity, and a non-threaded channel having at least one mounting cavity. The set of shaft elements surrounds the threaded shaft and the module. In the above-mentioned second end of the shaft element having a set of grooves of the shaft elements and a set of protrusions of the shaft elements of the above-mentioned case, the first end of the above-mentioned shaft element is movably installed, while in the cavity of the module with an inclined edge of the above-mentioned shaft element, the conical part of the above-mentioned module with an inclined height is movably installed, and in the groove of the module connection of the above-mentioned shaft element, the anti-rotation connection of the above-mentioned module is movably installed. The shell surrounds at least a set of shaft elements. The shell is made of elastic material. When the control device rotates in the direction of increasing the above-mentioned shell girth, the threaded shaft also rotates, and the rotation of the module around the longitudinal axis of the above-mentioned threaded shaft is prevented by the counter-rotating connection of the above-mentioned module, movably installed in the groove of the connection of the module of the above-mentioned shaft element moving along the threaded shaft. In this case, the conical part of the above-mentioned module with an inclined height passes along the inclined edge of the cavity of the above-mentioned module with an inclined edge of the above shaft element outside the inclined edge of the cavity of the above-mentioned module with an inclined edge of the above-mentioned shaft element, while each shaft element of the above-mentioned set of shaft elements moves perpendicular to the longitudinal axis of the above-mentioned threaded shaft in the direction opposite to the above-mentioned longitudinal axis of the above-mentioned threaded shaft. The shell is elastically deformed relatively to its original shape and the girth of the above-mentioned shell increases when the girth of the above-mentioned shell is increased. When the control device rotates in the direction of reducing the above-mentioned shell girth and the threaded shaft rotates, the rotation of the module around the longitudinal axis of the above-mentioned threaded shaft is prevented by the anti-rotation connection of the above-mentioned module, movably installed in the groove of the module connection of the above-mentioned shaft element, moving backwards along the threaded shaft. In this case, the shell again takes its original shape, and the conical part with an inclined height of the above-mentioned module passes back along the inclined edge of the above-mentioned module cavity with an inclined edge of the above-mentioned shaft element inside the above-mentioned module cavity with an inclined edge of the above-mentioned shaft element. Each shaft element of the above-mentioned set of shaft elements returns perpendicular to the longitudinal axis of the above-mentioned threaded shaft in the direction of the above-mentioned longitudinal axis of the above-mentioned threaded shaft, and the girth of the above-mentioned shell decreases, while the increase in the girth of the above-mentioned shell and the decrease in the girth of the above-mentioned shell are repeated. In accordance with the second embodiment of the device with an adjustable girth for expanding and stretching the body hole, the channel of the control device and the channel of the case are selected from a group including: a non-threaded channel, a threaded channel, a threaded channel having at least one fixing cavity, and a non-threaded channel having at least one fixing cavity. In the above-mentioned channel of the control device, the second end of the above-mentioned control device and the first end of the above-mentioned threaded shaft are installed. The threaded shaft is installed in the above-mentioned channel, and the module is connected to the threaded shaft. In accordance with the third embodiment of the device with an adjustable girth for expanding and stretching the body hole, at least one control device has a second end having a threaded shaft and a channel selected from a group including: a non-threaded channel, a threaded channel, a threaded channel having at least one fixing cavity, and a non-threaded channel having at least one fixing cavity. The threaded shaft is installed in the above-mentioned channel of the module, and the module is connected to the threaded shaft. In accordance with the fourth embodiment of the device with an adjustable girth for expanding and stretching the hole, the case has at least one counter-rotating protrusion of the module, as well as a non-threaded channel. In the counter-rotating cavity of the case of the above-mentioned module, the counter-rotating protrusion of the module of the above-mentioned case is movably installed, and the threaded shaft is installed in the above-mentioned channel. Rotation of the module around the longitudinal axis of the specified threaded shaft is prevented by the counter-rotating protrusion of the above-mentioned case, which is installed in the cavity of the counter-rotating protrusion of the case of this module moving along the threaded shaft. In accordance with the fifth embodiment of the device with an adjustable girth for expanding and stretching the hole, at least one control device has a threaded shaft channel selected from a group including: a threaded channel, a threaded channel having at least one mounting cavity, and a non-threaded channel having at least one mounting cavity. The case has at least one counter-rotating protrusion of the module. At least one module has at least one anti-rotation cavity of the case, and a module channel selected from a group consisting of: a non-threaded channel, a threaded channel, a threaded channel having at least one mounting cavity, and a non-threaded channel having at least one mounting cavity, wherein the anti-rotation protrusion of the module of the above-mentioned case is movably installed in the anti-rotation cavity of the case of the above-mentioned module, and the threaded shaft is installed in the above-mentioned channel of the module, and the module is connected to the threaded shaft.   
     EFFECT: inventions make it possible to create repeatedly, safely, gradually, accurately and conveniently a uniform and stable pressure on the entire side surface of the body hole.
