TECHNICAL FIELD

The present invention relates to a medical rehabilitation device, and particularly, to a postoperative functional exerciser for frozen shoulder.

BACKGROUND

frozen shoulder, is a disease characterized by cystic inflammatory adhesion and stiffness of shoulder and glenohumeral joints, pain of shoulder joint and limited movement in all directions (especially abduction, external rotation and rear protraction) and caused by a variety of diseases. According to disease characters, the frozen shoulder can be classified into primary frozen shoulder and secondary frozen shoulder. The primary frozen shoulder is also known as idiopathic frozen shoulder, and its exact cause is unclear. At present, a large number of studies focus on the clinical symptomatic treatment of the frozen shoulder, and treatment effects are quite different. The common clinical treatment mode is to arthroscopically release the intra-articular adhesions through operations.

Success or failure of arthroscopic release operations not only depends on the operating techniques of operators, but also depends on postoperative functional exercise modes. Effective postoperative exercise not only facilitates the recovery of the activity of the shoulder joint, but also facilitates the improvement of the muscle strength of the shoulder joint. Therefore, postoperative functional exercise is of vital importance. Since the main clinical manifestations of the frozen shoulder are external rotation pain and external rotation dysfunction of patients, the main purpose of the postoperative exercise is to exercise the external rotation function.

At present, there is no special rehabilitation equipment for postoperative frozen shoulder, and only large-scale comprehensive rehabilitation equipment purchased by hospitals can be used for functional exercise. Meanwhile, the large-scale rehabilitation equipment has expensive price and poor portability. After returning home, the patients lose the exercise equipment and cannot use the rehabilitation equipment for the functional exercise.

Technical Problem

For most patients with frozen shoulder, the first thing to be solved is the recovery of the external rotation function after shoulder joint operation. Moreover, the rehabilitation equipment with relative portability and low cost is needed so that the patients exercise rehabilitation actions informed by doctors at home.

OPTIMAL EMBODIMENTS OF THE INVENTION

To make the purpose, the technical solutions and the advantages of the present invention more clear, the present invention is further described in detail below in combination with drawings and embodiments. It should be understood that specific embodiments described herein are only used for explaining the present invention, not for limiting the present invention.

The present embodiment provides a postoperative functional exerciser for frozen shoulder, which is used for rehabilitation exercise after arthroscopic release operations of the frozen shoulder and is especially suitable for rehabilitation exercise for the external rotation function of the shoulder joint. As shown inFIG. 1andFIG. 2, the present embodiment comprises a hand push rod1, a restrictive band2for restricting the elbow, and a waist buckle for fixing the restrictive band. The waist buckle is arranged on the waist on a side opposite to an affected arm, and specifically arranged on top of trousers of a patient. The hand push rod1comprises a wristband11and a push rod12. One end of the push rod12is connected with the wristband11. When the hand push rod1and the restrictive band2are in operation, a part of the restrictive band2winds around the side opposite to the affected arm and penetrates through the waist buckle, and the other part winds around the elbow joint of the affected arm. The elbow joint of the affected arm is tied to an outer side of a rib of a body. The wristband11is sleeved on the wrist of the affected arm.

A part of the restrictive band2penetrates through the waist buckle on a side of the waist of the patient, and the other part of the restrictive band2winds around the elbow joint or upper arm of the affected arm. The upper arm is tied to the body by means of the restrictive band2, so that the elbow and the upper arm cling to an outer edge of the rib of the patient. In addition, the wristband11is sleeved on the wrist or forearm of the affected arm. The patient holds the push rod12through a non-affected arm and drags the wristband11through the push rod12, so as to drive the forearm to swing outwards. Of course, in the present embodiment, another person can hold the push rod12for rehabilitation exercise.

Further, in the present invention, a waistband4is also arranged; the waistband4winds around the body and is tied to the waist; and the waistband4penetrates through the waist buckle3. The waistband4and the restrictive band penetrate through the same waist buckle3to form fixation of the waistband4for the restrictive band. A relatively comfortable interlocking fixation structure is formed by the waistband4, the waist buckle3and the restrictive band2, so that the affected arm can be fixed to the outer rib of the body.

In the present embodiment, a buckle121is arranged at one end of the push rod12; the wristband11is provided with a buckle ring111; and the buckle121is fastened with the buckle ring111. Specifically, one end of the push rod12is provided with a cavity for accommodating the buckle ring111. Meanwhile, an opening is formed in the cavity, and the opening is closed through the buckle121.

As shown inFIG. 6, in a first embodiment of the buckle121, one end of the buckle121is hinged with one side of the opening, and the other end of the buckle121is abutted against the other side of the opening. The opening limits the buckle121to only swing towards the cavity. A torsional spring122is arranged at a hinging place. The other end of the buckle121is kept abutted against the other side of the opening through the torsional spring122, so that the cavity is closed, so as to prevent the buckle ring111from separating from the cavity after being clamped in. During use, the buckle ring111comes out of the buckle121and is pressed into the cavity; and under the action of the torsional spring122, the buckle121bounces back to close the opening.

As shown inFIG. 7, in a second embodiment of the buckle121, the buckle121is in sliding connection with the push rod12. The push rod12is provided with a sliding groove124. The sliding groove124is formed at one side of the opening, is axially formed along the push rod12, and points to the other side of the opening. The buckle121is arranged along the sliding groove124in a sliding manner. A pressure spring123is arranged in the sliding groove124. One end of the pressure spring123is fixed, and the other end is abutted against the buckle121. The pressure spring123drives the buckle121, so that the buckle121is abutted against the other side of the opening, to provide a driving force for the buckle121to bounce back to close the opening. During use, the buckle121is pushed by hand so that the buckle121moves along the sliding groove124. At this moment, the buckle ring111can be clamped into the cavity from the opening; and after the buckle121is released by hand, the pressure spring123drives the buckle121to bounce back to close the opening.

As shown inFIG. 2toFIG. 5, in the present embodiment, a rotating member112is arranged. One end of the rotating member112is rotatably connected with the wristband11, and the other end is provided with an installing hole; and the buckle ring111is arranged in the installing hole. Specifically, one end of the rotating member112is provided with a disk1121with a diameter greater than a diameter of the rotating member112. A rotating seat113is arranged. The rotating seat113is fixed to the wristband11. The rotating seat113is provided with a rotating cavity1131and a circular hole which is communicated with the outside and a rotating wall. The rotating member112penetrates through the circular hole. The disk1121is formed in the rotating cavity1131. In the present embodiment, the rotating member112can rotate in the rotating cavity1131; and the buckle ring111can swing around the axis of the installing hole to form universal connection between the buckle ring111and the wristband11, thereby avoiding mutual interference between the wristband11and the buckle ring111and facilitating the push rod12to draw the wristband11to move.

The push rod12comprises a plurality of telescopic sections; a head and a tail of adjacent telescopic sections can be connected flexibly; and the adjacent telescopic sections are provided with a positioning structure for positioning a telescopic state. Telescopic storage of the push rod12is realized through the telescopic sections, thereby shortening the storage length of the push rod12, facilitating logistics transportation and improving the portability of the present embodiment.

The wristband11is of a banded structure. Both ends of the banded structure are respectively provided with buckling structures which are matched with each other. Both ends of the banded structure are connected into a ring through the buckling structures. In a non-use state, two buckling structures are in a non-connection state and the wristband11is not buckled into a ring. During use, the wristband11winds around the wrist and the two buckling structures are buckled. After buckling, the perimeter of the wristband11is slightly greater than the perimeter of the wrist and smaller than the perimeter of a palm. In the present embodiment, the wristband11can be sleeved on the wrist without slipping from the palm.

As shown inFIG. 3, in the present embodiment, in an implementation manner of the buckling structures, the buckling structures are velcro114arranged on both ends of the banded structure respectively. The buckling of the wristband11in any position is realized through the velcro114, so as to facilitate adjustment of a proper perimeter of the wristband11, so that the wristband11and the wrist are adapted in sizes.

As shown inFIG. 4, in a second embodiment of the buckling structures, the buckling structures comprise an adjusting hole116formed at one end of the banded structure and an adjusting buckle115arranged at the other end of the banded structure; and the adjusting buckle115is buckled in the adjusting hole116. Specifically, the adjusting buckle115comprises a buckling frame1151and a buckling rod1152. The buckling frame1151is provided with four borders, wherein the first border and the second border are arranged oppositely and the first border is fixedly connected with the other end of the banded structure. One end of the buckling rod1152is hinged to the first border, and the other end is abutted against the second border. During use, one end of the banded structure penetrates through the buckling frame1151; the buckling rod1152penetrates through the adjusting hole and is lower than the second border; and the buckling rod1152is used to prevent the banded structure from being buckled loosely. Through the buckling between the adjusting hole116and the adjusting buckle115, the buckling is very firm.

The banded structure is flexible material. During tying, the flexible material is difficult to damage skin. Specifically, the banded structure is leather or cloth.

The postoperative functional exerciser for frozen shoulder in the present embodiment allows ordinary patients to have the economic ability to purchase the functional exerciser of the present invention, and to carry the functional exerciser of the present invention. The present invention allows the patients to receive postoperative rehabilitation exercise of the frozen shoulder without the limitations of economic capability, time and locations, makes the special rehabilitation of shoulder joint and frozen shoulder operations possible, has far-reaching significance for the development of arthroscopic radical operation of frozen shoulder, and is of great scientific significance to enrich and improve the existing medical rehabilitation equipment and lead the technological progress of relevant research fields.
