(54) DEVICE FOR DEVELOPMENT OF THE SHOULDER

I

The invention relates to medical technology, namely to a device for mechanotherapy, and can be used to restore the functions of the shoulder joint after radical removal of the mammary gland, the pectoral muscles, the psi and lymph nodes.

A device for developing a shoulder joint is known, which includes a housing, a lever and a handle that is pivotally connected to it and connected to the lever 1J.

However, in the known device there is no possibility of dispensing the load and changing the trajectory of rotational movements in the process of mechanotherapy. As a result, adaptation of the patient to power loads is difficult, restoration of joint function after mastectomy is difficult.

The purpose of the invention is the restoration of joint function after mastectomy.

The goal is achieved by the fact that in a device for developing a shoulder joint, comprising a housing, a lever connected to a handle, hingedly connected to it, the handle is made in the form of a gear rack, transitioning into a threaded rod, on which a counterweight with a counter nut is fitted, handles with a lever is fitted with a papeun and a sleeve with grooves, a gear wheel with a shaft is placed in the slider and meshes with the toothed rack, and the shaft is provided with a retainer, executed in the form of a button with a spring and a finger in contact with the slots of the slider and the sleeve.

The drawing shows a device for the development of the shoulder joint, partial sections.

The device comprises a housing 1 and an axis 2 to which a threaded rod 4 is attached with a flat hinge 3. One of the rod arms is provided with a screw thread 5, a counterweight 6 and a lock nut 7.

On the other arm of the rod there is a rack-and-pinion rack 8, which is located in the center with the gear 9, located in the slider Yu, covering this shoulder 392 along a sliding fit. A toothed rack 8, a transition into a threaded rod, forms a lever pivotally connected to housing 1. Gear 9 has a cantilever end, in which is located a spring retainer with a finger 11 and a control button 12. A bushing 13 is attached to the gear shaft, to which a handle 14 is attached. Similar groove 16 is made on the end of the sleeve 13. In addition, the lock in addition to the button and the finger is equipped with a spring 17. The device works as follows. In the position shown in the drawing, i.e. when the finger 11 is installed in the groove 16, the lock is turned off and when the handle 14 is rotated around the axis 2, the gear remains stationary relative to the handle 14, and the rail 8 is wrapped around gear 9, as a result the slider 10 moves along the rail up or down, depending on the direction of rotation of the handle. When the button 12 is rotated 9O, the button falls into the groove of the gear shaft, and the finger 11 enters the groove 15. In this position, the lock is on and when the handle 14 is rotated around the axis 2, the gear 9 remains stationary relative to the slide 10 and the rail 8. In this case regardless of the direction of rotation of the handle 14, the slider does not move along the rail 8 and the radius of rotation of the handle 14 relative to axis 2 remains constant. With the lock off, the patient, holding the handle, rotates his shoulders around the axis 2. At the same time, the slider 1O moves along the rail 8 at a distance of 55 mm per revolution, and the hand describes a spiral curve with a gradually increasing radius of Rotation. By changing the direction of rotation in the same way, the radius of rotation of the arm is reduced. When the latch is on, i.e. when the finger 11 is in the groove 15, the patient's hand describes the circumference of a constant radius, since the slider remains stationary relative to the lath 8. The force that the patient must apply to the handle is dispensed as instructed by the doctor using a counterweight 6 by moving it along a screw thread 5. The advantage of the proposed device is that depending on the constitution of the patient (his height, strength, age, etc.), the degree of development of the joint, and the level of pain, depending on the patient’s constitution set the required radius of rotation, dose the load and change them in one direction or another directly in the process of rotation. In this case, the patient has the opportunity to make turns of the shoulder, forearm and hand around the longitudinal axis of the arm. Due to this, it is possible to gradually increase the load and amplitude of movements, as a result of which the joint is improved, the pain is more easily overcome, which contributes to the speedy rehabilitation of the joint. In addition, the proposed device allows rotation of the hand, forearm, and shoulder around the longitudinal axis, which contributes to an increase in the range of motion in the radial joint. The invention The device for developing a shoulder joint, comprising a body, a lever pivotally connected to it, connected to a handle, which is designed so that, in order to restore the function of the joint after mastectomy, the lever is implemented in the form of a toothed rack, turning into a threaded rod, which has a counterweight with a lock nut, at the junction of the handle with the lever, a slider and a sleeve with grooves are installed, a gear with a shaft is placed in the slider, which is in engagement with the gear rack, and the shaft is provided with a lock made in de buttons with a spring and a finger in contact with the slots of the slider and sleeve.
