The invention also relates to a method for relative movement of a leg and a portion of a hip using an orthopedic device.

In addition, the invention relates to a method for performing a procedure with a hip area by implementing a method using an orthopedic device.

The level of technology

In the prior art disclosed orthopedic equipment designed to move the leg and the thigh relative to each other, and the thigh is located on the support base, under which is attached the first end of the elongated support rail, made with the possibility of moving the support node for the leg has a free end fitted with a knob for an adjusting element designed to limit the movement of the supporting rail, and a support unit for the leg n Rice connected to a supporting rail with the possibility of movement. Among these parts of orthopedic equipment, a supporting rail attached to a support base has horizontal and vertical trajectories of movement, controlled by two spherical hinges with a fixed relative position. Such an orthopedic device is very difficult in terms of both the design and the locking mechanism for spherical hinges.

DISCLOSURE OF INVENTION

Using the above-mentioned known level of technology as a starting point, the author set his goal to offer an orthopedic device with the ability to provide leg movements relative to the hip joint, similar from the user's point of view, obtained in orthopedic equipment of the known level of technology in which the design of the actual device would be much simpler and more reliable in terms of controlling and fixing support rail paths than in equipment known from technology.

These goals are achieved using an orthopedic device according to claim 1, as well as the method according to claim 11 for the movement of the leg and thigh area relative to each other using an orthopedic device according to claim 1.

More specifically, the invention relates to an orthopedic device designed to move the leg and the thigh relative to each other, comprising a support base for supporting the thigh portion under which the first end of the elongated support rail is attached, capable of moving the support assembly for the leg, wherein said the supporting rail has a second, free, end, fitted with a handle for an adjusting mechanism intended for fixing and unlocking; movement of the rail when moving, and the support node for the leg, mounted on a supporting rail with the possibility of movement. The device comprises a first adjustment mechanism comprising a pair of gas springs located between the first end of the support rail and the brackets attached to the support base, preferably under the support base, and used to control the fixation of the support rail during movement and create the force required to rotate the support rail, and also, in addition, the second adjustment mechanism, equipped with a universal joint and together with the first adjustment mechanism Horizontal and vertical paths of movement of the supporting rail relative to the support base, as well as connecting the first end of the supporting rail can be rotated under the support base or to the brackets attached under the support base.

The preferred embodiment of the present invention is based on the use of a supporting rail in a device connected to a support base by means of a universal hinge, used to regulate the amount of movement of the supporting rail along vertical and horizontal paths. In addition, the vertical and horizontal trajectories of the supporting rail, as well as the fixing of the supporting rail and the force required to move the rail, are regulated by two pairs of gas springs, which are connected to the brackets under the support base on one side and to the other side horizontal rotating shaft (middle shaft) passing through the universal joint, as a result of which the gas springs always remain co-directed with the support base. Rotating the support rail horizontally or vertically relative to the support base changes the length of the gas springs between the brackets and the middle shaft, and thereby affects the amount of force required to rotate the support rail. The position of the piston rod of the gas springs relative to the corresponding cylinder and at the same time the position of the supporting rail relative to the universal joint and the supporting base are fixed by means of a lever system controlled by a handle located on the free end of the supporting rail. Such a universal joint, which regulates the trajectories of the supporting rail, and a pair of gas springs that fix the supporting rail, form a surprisingly simple structure.

The invention also relates to an orthopedic device for moving the leg and the thigh section relative to each other, comprising a support base for supporting the thigh section under which the first end of the elongated support rail is attached, capable of moving the support node for the leg, wherein said supporting the rail has a second, free end, fitted with a knob for an adjusting mechanism designed to fix and unlock the supporting p when moving, and supporting the leg, attached to the supporting rail with the possibility of movement. The method includes the following steps:

place the foot on the support node for the leg so that the hip portion of this leg is located on the supporting base so that the hip joint is located in the direction of the plane of the supporting base in a place different from the longitudinal axis of the universal joint, i.e. vertical shaft passing through universal joint;

open the clamping mechanism acting on a pair of gas springs of the first adjusting mechanism, as well as the locking engagement of the support assembly for the leg with the supporting rail;

move the supporting rail and the leg supported by it through the support node to change the position of the leg relative to the hip joint supported by the supporting base, while the movement of the supporting rail at the same time the legs in the vertical and horizontal directions relative to the supporting base are determined by the first adjustment mechanism containing a pair of gas springs located between the first end of the support rail and the brackets attached under the support base, kneading those with a second adjustment mechanism equipped with a universal joint;

fix the position of the piston of each gas spring relative to the cylinder of the corresponding gas spring, and also create a locking engagement of the support assembly for the leg with the supporting rail, while simultaneously fixing the position of the leg relative to the corresponding hip joint.

The invention also relates to a method for performing a procedure with a hip area by implementing a method using an orthopedic device according to any one of claims 1 to 10 for movement of the leg relative to the hip joint placed on a support base. The method includes the following steps:

place the foot on the leg support unit so that the hip area is located on the support base so that the hip joint is located in the direction of the plane of the support base in a place other than the vertical shaft passing through the universal joint;

open the locking engagement of the first adjustment mechanism containing a pair of gas springs;

move the supporting rail and the foot supported by it in such a way that the length of the paths of movement of the supporting rail in the vertical and horizontal directions is determined by the first adjustment mechanism equipped with a universal joint;

fix the position of the piston (rod) of each gas spring relative to the cylinder of this gas spring;

perform the procedure with the thigh, for example, receiving the image.

Another advantage gained by using a gas spring when fixing the movements of the supporting rail attached to the universal joint of the supporting rail is that the lifting movements of the supporting rail are facilitated by the use of gas springs.

In another preferred embodiment of the present invention, the clamping lever system comprises a tension rod or similar element extending inside the support rail, which is attached to the handle and adapted to act with elongated fittings on the piston end of each gas spring so that the piston of said gas springs in the corresponding cylinder at the same time was in a detachable and fixed position.

In another preferred embodiment of the present invention, the elongated fasteners have a first end attached to a tension rod and a free end provided with a horizontally swivel grip (hook). There are protrusions that can be rotated along with the middle shaft. The connecting parts of the lever system are attached close to the hook located at their free end, with the possibility of rotation in the horizontal plane to a vertical pin attached respectively to the middle shaft extending inside the protrusion. Each hook, along with a connecting piece acting on the end of the gas spring, is located on the fastening element of the gas spring. When bringing the hook into contact with the gas spring connecting piece, the engagement between the hook and the vertical pin, i.e. gas spring fastener will open. At the same time, the fixing between the gas spring piston and the cylinder stops.

The connecting piece is preferably spherical, with the hook and connecting

- 2 029871

the part preferably has the same radius of curvature.

The horizontal movement of the supporting rail is restricted in such a way that the horizontal movement is limited by an element preventing rotation of the rotary shaft passing through the upper connecting element of the universal joint, such as a groove on the surface of the upper connecting element, aligned with the counter part of the groove located in the opening of the connecting element in the support base or in the hole of the connecting element in the brackets under the base. On the other hand, with the possibility of limiting the vertical displacements of the supporting rail, mutual form-blocking engagement of the lower connecting element and the upper connecting element is preferably performed, preventing these connecting elements from rotating relative to the universal joint hinge shaft.

In short, the horizontal movements of the supporting rail may be limited by an element preventing rotation of the rotary shaft P1 passing through the upper connecting element of the universal joint, such as a groove on the surface of the upper connecting element aligned with the counterpart on the supporting base or its brackets be limited by mutual formablocking engagement of the lower connecting element and the upper connecting element.

In this context, horizontal or vertical movement of the support rail is perceived as horizontal or vertical rotation around the anchorage point located at the junction of the end of the support rail attached to the lower connecting element and the lower universal joint.

The implementation of the invention

The following is a brief explanation of the aspects of the present invention represented by each figure, as well as the main structural elements of the device 1 shown in the figures.

The device 1, most shown in general in FIG. 1A and 1B, is intended to move the leg and the hip area relative to each other and contains a support base 2, designed to support the thigh section, while under it the first end 3b of the elongated support rail 3 is attached, capable of moving the support assembly 8 for the leg. The supporting rail 3 has a second, free, end 3a provided with a handle 6 for an adjusting mechanism for fixing the supporting rail during movement, while the supporting leg assembly 8 is attached to the supporting rail 3 with the possibility of movement. The above-mentioned components of the device can also be found in most publications related to the prior art, therefore traditional modifications of the considered components are considered to be included in the scope of the legal protection of the device according to the present invention.

The device 1 also contains a first adjustment mechanism comprising a pair of 4 gas springs located between the first end 3b of the supporting rail and the brackets 20 attached under the base 2. using a clamping mechanism 300, partially visible in FIG. 1B.

In addition, the device contains a second adjustment mechanism, equipped with a universal joint 5, which determines the length of the paths of movement of the supporting rail 3 in the vertical direction. 3 029871

and horizontal directions, possibly together with the first adjustment mechanism and attached to the first end 3b of the supporting rail 3 under the support base 2 or to the brackets 20 (gas spring) attached to the lower side of the support base 2. FIG. 1A also shows substantially traditional pillows 91, 92 for the support base.

FIG. 2A and 2B show the construction of the aforementioned universal joint 5 more accurately. The universal joint 5 has an upper connecting element 51 connected by an upper end to the supporting base 2 or to the brackets 20 attached to the supporting base 2 and extending from it downwards. The lower end of the upper connecting element 51, in turn, is connected with the help of a hinge shaft 53 to the lower connecting element 52, which has a L-shaped external shape and, in turn, is fixedly connected with its lower end to the first end 3; 3b supporting rail. The upper connecting member 51 and the lower connecting member 52 of the universal joint are positioned relative to the hinge shaft so as to allow the upper connecting member 51 of the universal hinge to rotate in a horizontal direction around the longitudinal axis P1 and allow the lower connecting member 52 to rotate in a vertical direction around the hinge shaft 53, functioning as a rotation axis. Thus, it is thanks to the universal joint 5 that the vertical and horizontal movements of the supporting rail 3, fixedly coupled to the lower connecting element 52, are possible; the vertical rotation occurs around the horizontal axis P2 passing through the hinge shaft 53, and the vertical rotational movement occurs around the vertical axis P1 passing through the universal joint 5. The horizontal and vertical movements of the supporting rail 3 are limited due to the fact that the horizontal rotation of the upper member 51 is limited universal hinge 5 around the longitudinal axis P1 and the vertical rotation of the lower element 52 relative to the hinge shaft 53.

In this case, the horizontal and vertical movements of the supporting rail 3 relate respectively to the movements of the supporting rail relative to the horizontal direction determined by the plane of the horizontal support base 2 and the vertical direction transverse to this horizontal direction. Supporting rail 3, as a rule, is placed in a horizontal direction or in a direction that deviates slightly from it.

Using FIG. 3A-3C and also partially in FIG. 2A illustrates the design and operation of the first adjustment mechanism used for balancing and fixing the movements of the support rail 3. As already noted in connection with FIG. 1A and 1B, the first adjustment mechanism comprises a pair of gas springs 4 located between the first end 3b of the supporting rail and the brackets 20 attached under the support base 2. More specifically, the pair of gas springs 4 under consideration is provided by the gas spring fixtures 38 to a horizontal rotary shaft 39, or an average shaft 39, passing through the universal joint. Both protrusions 35 and the middle shaft 39 (body of revolution) are provided with concentric holes 35a, 39a in the place where the gas spring is inserted inside the protrusion 35 and fed to the edge grooves at the ends of the middle shaft 39.

The fixing of the gas springs is controlled by means of a clamping mechanism 300 comprising a handle 6 located at the free end 3a of the supporting rail 3 and configured to use the lever system 30 to act on the ends 41c, 42c of the gas spring in such a way that fix and release the gas spring piston rod 41a, 42a relative to the corresponding cylinder 41b, 42b.

After connecting the gas springs 4; 41, 42 to the connecting parts 32; 32 'and 32; 32 "of the lever system located in the end grooves 34 of the shaft 39, the position of the piston rods 41a, 42a of the gas spring relative to the cylinders is fixed, as is the relative position between the lever system 30 and the gas springs 4, which prevents the tension of the tension rail 3 from moving relative to the gas springs 4, as well as the lever system passes inside the tension rail.

The rotation of the gas springs 4 connected in a detachable manner to the end grooves 34 of the middle shaft 39, and at the same time the rotation of the supporting rail 3 relative to the gas springs 4 are made with the possibility of limiting, on the one hand, the limiting surfaces 34a of the end grooves 34 of the middle shaft 39, and the inner edge 34b of the groove, and, on the other hand, the outer edge 34c of the groove 34. Similarly, the edges of the aperture 35a, 39a can also act as limit stops for the rotation of the gas springs 4.

The angle of rotation of the supporting rail 3 relative to the gas springs may also be limited by fastening elements 38 of the gas springs connecting with end grooves 34 located at the ends of the middle shaft 39. The ends 41c, 42c of the piston rods of the gas springs 4; 41, 42 are attached to these fasteners 38 of the gas springs in a manner that allows the clutch to open between the gas spring piston and the cylinder. Although the coupling between the cylinders and the piston rods is open, the relative rotational movement between the gas springs 4 and the middle shaft 39 in the plane passing through the gas springs nevertheless prevents the adhesion between the ends 41c, 42c of the piston rods 41a, 42a and fasteners 38 gazo- 4 029871

out springs.

The fastening elements 38, attached to the end grooves 34, also act as stops 38, limiting the rotational movement of the shaft 39 around its longitudinal axis.

Using FIG. 4A and 4B illustrate a device for fixing a carriage 7 supporting the support assembly 8 on the supporting rail 3. In the following, the invention will be described in more detail with reference to the preceding general description of the invention, and also in FIG. 1-4.

Inside the hollow support rail 3 in the device according to the present invention, a tension rod 31 extends from the lever system 30 of the clamping mechanism 300 and extends along the entire length up to the free end 3 a of the supporting rail 3.

A lever 62 is attached to the end of the tension rod 31, intended for the handle 6 and located at the free end of the supporting rail 3. The lever 62 acts on the tension rod 31 of the lever system 30 so that it allows the cylinder and the piston of the gas springs 4 to be fixed to each other.

The tension rod 31 of the lever system 30 extends to a hollow middle shaft 39 connected perpendicularly to the junction of the end 3B of the supporting rail 3 and the lower element 52 of the universal joint 5 at the end of the supporting rail 3 closest to the support base 2.

Through the end 3B of the supporting rail 3, connected to the lower element 52 of the universal joint 5, the axis of rotation passes, i.e. the middle shaft 39, horizontal in the transverse direction or aligned with the support base 2.

The ends of the middle shaft 39 protrude from the support rail 3, surrounded by hollow protrusions 35. The middle shaft 39 includes a pivot pin through which a central hole (central channel) passes. At each end of the middle shaft 39, the central bore expands to form an end groove 34 bounded in the longitudinal direction of the middle shaft 39 by the first guide or a restricting surface 34a diagonally relative to the lateral direction of the middle shaft (rotary axle) 39 closest to the center hole. The second bounding surface along the length of the groove 34 of the middle shaft 39 is formed by the outer edge 34c of the groove 34. If the middle shaft 39 is designed so that its ends are open, the rotation of the gas springs relative to the middle shaft 39 in the direction transverse to the specified middle shaft 35

Inside the hole going through the middle shaft 39, are the connecting parts 32; 32 ', 32' lever system, first, internal, ends 32; 32b; 32 '', 32 'of which are pivotally connected to the tension rod 31. The connection with the tension rod 31 is made from the coupling point of the supporting rail and the middle shaft by means of an articulated joint 33, such as a stud 33. The outer ends of the connecting parts 32 are loose in relation to shaft 39, designed in the form of hooks 32a and 32 "a, passing to the fastening elements 38 of the gas springs 4 located in the end grooves 34 of the middle shaft 39. In the lever system there are connecting parts 32; 32 'and 32; 32 "attached to a vertical pin 36, such as a pin 36, passing through a rotary pin with the possibility of rotation in the horizontal plane near the hook 32'a or 32" and located at their free end.

On the middle shaft there are end grooves 34, fitted with fasteners 38 gas springs, mounted to rotate in a horizontal plane in the end grooves 34, located at both ends of the middle shaft 39. If you look from the sides 3c, 34 supporting rail 3, the end grooves 34 are approximately at right angles to the ends of the middle shaft. Inside each of them, the hook 32a, 32a "of the elongated fitting 32" or 32 "of the lever system 30 is positioned so as to be rotatably mounted in the transverse direction or in the direction of the gas springs to the fastening pins 38a located on the upper end of the fastening elements 38 gas springs. The gas spring fasteners 38 also engage the gas spring piston ends 41c, 42c so that the functional communication channel between the lever system 30 and the gas springs 4 opens and closes using spherical fittings 44 that move at the gas ends 41c, 42c. springs. After the communication channel between the gas spring cylinders 41b, 42c and the piston ends 41c, 42c is opened by attaching the lever system 30 to the gas spring 4, the shaft will thus be functionally connected to the gas spring 4, as a result of which the gas springs 4 can be rotated relative to the shaft 39 in the horizontal direction within the range defined by the movement stops 34a, 34b, and also 34c located in the end grooves. Since the shaft 39 can be further rotated away from the tension rod 3 around its longitudinal axis and transversely in the direction of the support base, the gas spring also acts on these trajectories of the shaft 39 and the tension rod 3 attached to the shaft.

Each hook 32'z and 32 "and can be brought into contact with the end 41c or 42c of the piston rod of the gas spring 4, pulling the tension rod 31 using the lever 62 of the handle 6 in the direction of the free end 3 and the supporting rail 3.

When the lever system 30 is triggered by the handle lever in such a way that the tension rod

- 5 029871

31 moves in the direction of the free end of the supporting rail 3, the inner ends 32L ', 32b "of the connecting parts 32 will also be tightened by the tension rod 31 by means of the articulated joint 33 in the direction of the free end 3a of the supporting rail. As a result a, located at the free ends of the connecting parts 32 'and 32 "and installed rotatably with the help of vertical pins 36 on fasteners 38 of the gas springs, will rotate in the end grooves 34 around the vertical pin 36 horizontally to the cylinders 41b, 42b of the gas springs 41, 42. When the hooks 32a and 32 "a located on the fasteners 38 of the gas springs turn away from the fasteners 38 of the gas springs, this leads to the hooks 32a and 32 "of the tension rod are pushed and come into contact with the spherical connecting parts 44 of the gas springs. The connecting parts 44 and the hooks 32a and 32" are moved away from the fastening elements 38, opening the locking coupling between the piston and the cylinder 41b, 42b gas springs 41, 42 and allowing gas springs 4 rotate together with the movement of the shaft 39 and at the same time the movement of the supporting rail 3.

Accordingly, tightening the lever, which is part of the handle 6, by the control lever system 30 of the clamping mechanism 300, causes horizontal rotational movement of the hooks 32a and 32 "a located at the end of the elongated connecting parts 32; 32 ', 32' attached to the tension rod 31 extending inside the support rail 3. They act on the end 41c, 42c of the piston 41a, 42a of each gas spring 41, 42 simultaneously with the connecting parts 44 of the gas spring.

The free ends 41c, 42c of the gas springs are pivotally connected to the fastening elements 38 of the gas springs. Thus, fixing the free ends 41c, 42c of the gas springs 41, 42 to the fasteners 38, when the hooks 32a, 32 "and are again attached to the fasteners of the gas springs away from the gas springs, also causes the supporting rail 3 to be fixed relative to the gas springs 4, since the tension rod 31 extending inside the support rail 3 is attached with hooks to the fastening elements 38, thereby preventing relative rotation between the middle shaft 39 and the tension rod around the longitudinal axis of the middle shaft. iknoveniyu locking clutch facilitated by the fact that the hooks 32'a, 32 "a and the coupling parts 44 gas springs have substantially the same radius of curvature.

In the absence of a locking clutch between the piston rods and the cylinders 41L, 42B of the gas springs 41, 41 pairs of gas springs 4, the latter will have a balancing and increasing accuracy effect on the movement of the supporting rail 3. The fastening elements 38 of the gas springs 41, 42 are inserted into the end grooves 34, which also provides the possibility of rotation in the mutual longitudinal direction of the gas springs 4 and the supporting rail 3 in the plane passing through the gas springs 41, 42 after the locking engagement between the gas and the springs 4 and the lever system 30 will be opened.

The gas springs 41, 42, which can be connected to the fasteners 38 of the gas springs to form the locking engagement, have ends 41c, 42c of the piston rods 41, 42 mounted in the horizontal and vertical directions, i.e., as in the plane through gas springs, and in the direction transverse to the plane of the gas springs, with the possibility of rotation on the fastening element 38 of the gas springs remaining inside the end protrusion 34 of the middle shaft 39.

The gas spring fastener 38 is connected to the middle shaft 39, which is able to rotate relative to the tension rod 3 in the range permitted by the hole 35a, 39a, thus providing, for its part, the possibility of vertical movements of the tension rod 3 when the gas springs turn with the middle shaft. As a consequence, rotation of the supporting rail 3 relative to the end of the gas springs 41, 42 causes a change in the distance between the ends 41c, 42c of the gas springs 41, 42 mounted on the middle shaft 39 and the part mounted on the brackets 20 of the supporting base, which leads to a corresponding change in the length of the gas springs 41, 42.

Turning the support rail 3 in a horizontal direction around the vertical axis P1 passing through the universal joint 5 causes the first gas spring to lengthen and the second gas spring to shorten.

On the other hand, turning the support rail 3 in a vertical direction around the hinge shaft 53 causes each gas spring 41, 42 to shorten or lengthen simultaneously. It is the extension of each gas spring 41, 42 that balances the rotation of the support rail 3 upwards. Thus, turning the lower coupling element 52 fixedly connected to the end of the supporting rail 3 in the vertical direction around the horizontal axis P2 of the universal joint 5 located on the hinge shaft 53 causes the supporting rail 3 to rotate relative to the middle shaft 39, which is horizontal or aligned with the support base and passes through the lower element 52 of the universal joint. As a result, the connecting parts 32 ', 32 "mounted centrally on the middle shaft 39, and the ends 42c, 41c of the gas springs rotate together with the middle shaft 39 relative to the supporting rail 3 so that the direction of the gas springs 41, 42 relative to the support base 2 remains the same.

- 6 029871

When fixing the engagement between the ends 41c, 42c of the piston rods and fasteners 38 of the gas springs 41, 42, the position between the piston and the cylinder of each gas spring will be fixed simultaneously, which will prevent the supporting rail from moving in the vertical and horizontal directions.

FIG. 3A shows a state in which the hooks 32a and 32 "a, located on the fasteners 38 of the gas springs, are brought into contact with the spherical connecting parts 44 acting on the free ends 41c, 42c of the pistons of the gas springs 41, 42. At this moment the ends 41c, 42c of the piston rods 41a, 42a of the gas springs are still attached to the fasteners 38, 38 of the gas springs, but the position between the piston rod 41a, 42a and the lever system 30 is no longer fixed. Piston rods 41a, 42a can rotate relative to the fasteners 38 in the plane passing through the gas springs 4; 41, 42, as a result of which the angle of the longitudinal direction of the shaft 39 relative to the longitudinal direction of the gas springs 4 will simultaneously rotate in the specified plane passing through the gas springs 4. The angle between the longitudinal direction of the shaft 39 and the longitudinal direction gas springs can be rotated in the range defined by the bounding surfaces 34a, 32b, and also 34c of the groove 34.

If the shaft 39 is open at the ends, the angle between the longitudinal direction of the shaft 39 and the longitudinal direction of the gas springs can be rotated in the range defined by the bounding surfaces 34a, 32b of the groove 34, as well as the surface of the protrusion 35 located at the top of the groove. Since the supporting rail 3 is attached to the universal joint 5 so that the shaft 39 passes through the lower connecting element 52 of the universal joint and through the supporting rail, and always in the transverse direction relative to the supporting rail 3, the angle between the longitudinal direction of the shaft 39 and the longitudinal direction of the shaft gas the springs also determines the angle between the supporting rail 3 and the gas springs 4, i.e. the distance that the supporting rail 3 can be rotated relative to the longitudinal direction of the gas springs 4 in the plane passing through the gas springs 4.

Since the ends 41c, 42c of the piston rods 41a, 42a are mounted for rotation in a horizontal plane on the fastening elements 38 of the middle shaft 39, and the middle shaft 39 rotates horizontally relative to the supporting rail 3, turning the supporting rail 3 causes the gas springs 41 to lengthen or contract 42 depending on the direction of movement of the supporting rail 3.

The ends 41c, 42c of the piston rods 41a, 42a of the pair of gas springs 4 can also be secured with fasteners 38 of the gas springs with hooks 32a, 32 "and of the lever system 30, which prevents the gas springs 4 on the middle shaft 39 from turning in the horizontal direction, and also rotating the middle shaft 39 relative to the supporting rail 3, thereby fixing the relative position of the gas springs 4 and the supporting rail 3.

Supporting rail 3 can be further rotated in horizontal and vertical directions by an angle, the value of which is determined by universal joint 5, when the horizontal direction is perceived as a plane passing through the reference level 2.

In the device according to the present invention, disclosed in the foregoing embodiment, the amount of movement of the supporting rail 3 in the horizontal and vertical directions (if the direction of the support base 2 is regarded as the horizontal direction) can be adjusted mainly by means of the universal joint 5 connected between the end 3b supporting rail 3 and the support base 2.

The horizontal and vertical movements of the supporting rail 3 can also be limited by means of the universal joint 5. In the preferred embodiment of the present invention disclosed above, the protrusions 35 are rotatable along with the middle shaft 39, while the horizontal movements of the supporting rail 3 are limited in this way so that horizontal movements are limited to some element, such as a groove on the surface of the upper connector th element 51, limiting the rotation of the rotating shaft P1 passing through the upper connecting member 51, and combines with the mating groove located in the bore of the connecting element to the support base or in the bore of the connecting element in the brackets 20 under the base. In this regard, the vertical movement of the supporting rail 3 can be limited with the help of the relative form-blocking engagement of the lower connecting element 52 and the upper connecting element 51.

The universal joint 5 has an upper connecting element 51 mounted for rotation in a horizontal plane on the support base 2 or on the brackets 20 attached thereto in order to allow horizontal pivoting movements of the supporting rail 3 around the longitudinal axis of the universal joint. The lower or lower connecting element 52, in turn, is connected by means of a hinge shaft 53 to the upper or upper connecting element 51, to allow vertical pivoting movements of the supporting rail 3 around the hinge shaft 53.

Below is a further description of the operation of the device 1 in accordance with the present invention, perceived from the user's point of view.

When using an orthopedic device 1 according to the present invention, the patient places his foot on the leg support unit 8. Thereby, the patient’s hip and, in particular, the hip joint is supported by the supporting base 2 so that the vertical plane passing through the hip joint crosses the plane of the supporting base 2 in a place different from the longitudinal axis P1 of the universal joint. After that, the clamping mechanism 300 acting on a pair of gas springs 4 of the first adjustment mechanism is opened by pushing the lever of the handle 6, as a result of which the tension rod 31 of the lever system 30 delays the connecting parts 32 in the direction of the free end 3a of the supporting rail, and the hooks 32a at the ends the connecting parts turn and come into contact with the connecting parts 44 of the gas springs, opening the locking engagement of the pair of gas springs 4, despite the fact that the ends 41c, 42c of the piston gas spring rods are constantly engaged with fasteners 38.

Since the vertical plane passing through the hip joint of the leg intersects the plane of the support base 2 in a place different from the longitudinal axis P1 of the universal joint, then after or simultaneously the locking engagement between the carriage 7 of the support assembly 8 for the leg and the locking handle 88 open, and the carriage 7 could move along the supporting rail 3 when the supporting rail 3 was rotated.

When pressing the carriage handle 88 due to the eccentric shape of the handle, pressure is applied through the washer 86 to the fixing unit 84 with four cylindrical protrusions having chamfers taken at the ends at an angle of approximately 45 °. These beveled faces apply a wedging pressure to the two upper corners of the tension rod inside the pulling device, thereby pressing the lower surface of the tension rod to the slider 82 inside the pulling device. Slider 82 has a higher friction than other sliding surfaces, while fixing is more effective. At the same time, three-point fixation eliminates the gap of the carriage 7 relative to the tension rod.

The handle 88 has an eccentric bore hole for the stud 8 located inside the handle. When turning the knob 88 up, the locking block 84 rises up under the action of the spring underneath, consequently the slider 82 comes out of contact with the supporting rail, thereby allowing the carriage 7 to move along the supporting rail 3.

The supporting rail 3 can now be rotated in horizontal and vertical directions of the support base 2 around its vertical and horizontal axes P1, P2 located on the universal joint, in the range allowed by universal joint 5 and the engagement between the gas springs 4 and the shaft 39. At the same time the leg supported by the support unit 8 will change its position relative to the hip joint, supported by the support base 2.

After reaching the desired position of the leg with respect to the hip joint located on the support base 2, the position of the piston rod 41a, 42a of each gas spring 41, 42 relative to the cylinder 41b, 42b of the corresponding gas spring is fixed by attaching the end 41c, 42c of the piston rod with a fastener gas spring to the lever system 30. At the same time, as a result, the position of the leg relative to the hip joint is fixed. The gas springs 4 are fixed when the lever system 30 of the clamping mechanism 300 is actuated using the lever 62 of the handle 6 to cause the hooks 32a and 32 "a to be rotated at the end of the elongated connecting parts 32; 32 ', 32' attached to the tension rod 31 extending inside the support rail 3 in the plane defined by the gas springs coming out of contact with the connecting piece 44 acting on the end 41c, 42c of the piston rod 41a, 42a of each gas spring 41, 42. This is followed by fixing the relative position of the base Bani 2 and carriage support assembly 7 to 8 feet, then the hip joint portion, located on the support base may be subjected to a procedure, for example by imaging.

Above, only a few preferred embodiments of the invention have been disclosed, and it is clear to a person skilled in the art that there are many other possible ways to implement the invention within the ideas of the invention presented in the claims.

Accordingly, in one embodiment of the invention, the protrusions 35 are fixedly mounted on the supporting rail 3, while the vertical movements of the supporting rail 3 can be limited not only by the universal joint 5, but also by movement limiters limiting the rotational movement of the middle shaft 39, 39, and linkage fittings 32 ′, 32 ″, which can be brought into contact with the protrusions 35 fixedly mounted on the supporting rail 4. Useful as ve limiters such displacement can be the fastening pins 38a fastener gas spring, brought into contact with the grooves located on the inner surfaces of the projections 35 which

prevent the rotation of the middle shaft 39.
