Description

Technical Field

[0001] The utility model belongs to the technical field of orthoses, and in particular relates to an elbow joint functional rehabilitation orthosis. Background Art

[0002] Elbow orthoses are generally used to help treat elbow injuries. In most cases, elbow injuries refer to deformation of the elbow flexion contracture or extension contracture, which affects the normal movement of the elbow. Orthoses can protect and fix the elbow during the patient's recovery process, relieve pressure on specific parts of the elbow joint, and reduce the pain of the patient during the recovery period.

[0003] Compared with the previous plaster fixation, the fixation of the elbow orthosis allows the patient's elbow to not be in a closed environment for a long time, and the angle of the elbow can be adjusted, so that the patient can change the fixation angle of the elbow according to their own situation. However, the arm lengths of different patients are also different. At present, the length of the splint part of most elbow orthoses is fixed, which can meet the needs of most ordinary people. It is inevitable that it will cause inconvenience to some patients with longer or shorter arms.

[0004] Therefore, we propose an elbow joint functional rehabilitation orthosis to solve the above problems. Summary of the invention

[0005] The utility model aims to solve the problem that the orthosis in the prior art is difficult to adjust its own length according to the arm length of the patient, and proposes an elbow joint function rehabilitation orthosis.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A functional rehabilitation orthosis of an elbow joint comprises two groups of rotating splints, two groups of extension splints and a plurality of straps, wherein the plurality of straps are respectively sleeved between the two groups of rotating splints and the two groups of extension splints, an extension plate is fixedly connected to the side wall of the rotating splint facing the extension splint, an insertion hole is provided on the side wall of the extension splint facing the rotating splint, the extension plate is inserted into the insertion hole, a cavity is provided in the extension splint, and a limiting mechanism for fixing the extension plate is installed in the cavity.

[0008] The utility model further defines the technical solution:

[0009] Preferably, the limiting mechanism includes a pressing block, a rotating rod and an inserting rod, the top wall of the extension plate is provided with a plurality of oblique slots, the top wall of the extension splint is provided with a through hole, the through hole is connected to the cavity, the pressing block is located in the through hole, one end of the pressing block extends into the cavity, a center rod is fixedly installed on the side wall of the cavity, the rotating rod is sleeved on the outside of the center rod, one end of the rotating rod is rotatably connected to the end of the pressing block extending into the cavity, and the other end is fixedly connected to the inserting rod, a spring is fixedly connected to the side wall of the rotating rod facing away from the inserting rod, the other end of the spring is fixedly connected to the top wall of the cavity, and the end of the inserting rod away from the rotating rod is inserted into one of the oblique slots.

[0010] Preferably, the bottom wall of the cavity is fixedly connected with a spring sheet, the side wall of the spring sheet facing the extension plate is fixedly connected with a limiting ball, the bottom wall of the extension plate is provided with a plurality of hemispherical grooves, and the limiting ball abuts against the inner wall of one of the hemispherical grooves.

[0011] Preferably, the height of the insertion hole is smaller than the height of the cavity, and a baffle is fixedly connected to the side wall of one end of the extension plate away from the rotating clamping plate, and the height of the baffle is greater than the height of the insertion hole.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1 As shown, an elbow joint functional rehabilitation orthosis comprises two groups of rotating splints 1, two groups of elongated splints 2 and a plurality of straps 3, wherein the plurality of straps 3 are respectively sleeved between the two groups of rotating splints 1 and the two groups of elongated splints 2, and the straps 3 can fix the two groups of rotating splints 1 together, and can also fix the two groups of elongated splints 2 together, and because the straps 3 are retractable, they can be adapted to patients with different arm circumferences. An elongated plate 4 is fixedly connected to the side wall of one end of the rotating splint 1 facing the elongated splint 2, and a plug hole 5 is provided on the side wall of the one end of the elongated splint 2 facing the rotating splint 1, and the elongated plate 4 is inserted into the plug hole 5.

[0021] The height of the insertion hole 5 is less than the height of the cavity, and a baffle 15 is fixedly connected to the side wall of the extension plate 4 away from the rotating clamping plate 1. The height of the baffle 15 is greater than the height of the insertion hole 5. The design of the baffle 15 prevents the extension plate 4 from being completely pulled out of the cavity. Horizontal rods 16 are fixedly connected to the inner walls on both sides of the cavity, and transverse grooves 17 are respectively opened on the side walls on both sides of the extension plate 4. Two horizontal rods 16 are respectively inserted into the two transverse grooves 17.

[0022] Reference Figure 2A cavity is provided in the extension splint 2, and a limiting mechanism for fixing the extension plate 4 is installed in the cavity. The limiting mechanism includes a push block 6, a rotating rod 7 and an insertion rod 8. A plurality of oblique slots 9 are provided on the top wall of the extension plate 4. A through hole is provided on the top wall of the extension splint 2, and the through hole is connected to the cavity. The push block 6 is located in the through hole. The through hole and the push block 6 are both located at the top of the extension splint 2. This position will not contact the patient's arm or body, so it will not affect the patient's normal movement when worn for a long time. One end of the push block 6 extends into the cavity, and a center rod 11 is fixedly installed on the side wall of the cavity. The rotating rod 7 is sleeved on the outside of the center rod 11. The center rod 11 is set in the middle position of the rotating rod 7, so the rotating rod 7 can rotate around the center rod 11. One end of the rotating rod 7 is rotatably connected to the end of the push block 6 extending into the cavity, and the other end is fixedly connected to the insertion rod 8. A spring 10 is fixedly connected to the side wall of the rotating rod 7 facing away from the insertion rod 8, and the other end of the spring 10 is fixedly connected to the top wall of the cavity. The end of the insertion rod 8 away from the rotating rod 7 is inserted into one of the oblique slots 9. Since the insertion rod 8 will make a circular motion under the drive of the rotating rod 7, in order to ensure that the insertion rod 8 can smoothly limit the position of the extension plate 4, it is necessary to set an oblique slot 9 that can be inserted obliquely.

[0023] Reference Figure 3 The bottom wall of the cavity is fixedly connected with a spring piece 12, which itself is elastic. In the initial state, the spring piece 12 will maintain a state of being against the bottom wall of the extension plate 4. The side wall of the spring piece 12 facing the extension plate 4 is fixedly connected with a limiting ball 13. The bottom wall of the extension plate 4 is provided with a plurality of hemispherical grooves 14, and the limiting ball 13 is against the inner wall of one of the hemispherical grooves 14.

[0024] The working principle is as follows: when the user needs to adjust the distance between the extension splint 2 and the rotating splint 1, the user needs to press the two buttons 6 at the same time to make the button 6 move downward, and the rotating rod 7 rotatably connected to the button 6 will be driven by the button 6 to rotate around the center rod 11, and at the same time compress the spring 10. Due to the rotation of the rotating rod 7, the insertion rod 8 will leave the oblique slot 9. At this time, the user can pull the extension splint 2 horizontally. The spring piece 12 and the limiting ball 13 set at the bottom of the cavity will make the process of pulling the extension splint 2 more stable and controllable to prevent the user from pulling too far at one time. When the user adjusts the extension splint 2 to a suitable distance, the button 6 can be released. Under the action of the spring 10, the insertion rod 8 will be inserted into a new oblique slot 9, so that the position of the extension plate 4 is fixed.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
