Description

Technical Field

[0001] The present invention mainly relates to the field of medical device castings, and particularly refers to a medical device casting device for muscle stretching and recovery. Background Art

[0002] In daily sports, muscle injuries often occur. After the emergency period of muscle injury, stretching training can be used to repair and treat the muscle. Existing rehabilitation training equipment generally drives the active movement of the joint near the injured muscle through moving parts, thereby driving the stretching of the injured muscle to achieve the repair effect. It has no direct stretching effect on the injured muscle, and the rehabilitation treatment cycle is relatively long. Therefore, there is an urgent need for a medical device that can help patients quickly recover their muscles. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a medical device casting device with a reasonable structure, which can simultaneously produce active and passive stretching of the injured muscle, and can quickly recover the injured muscle through the dual stretching function of the muscle.

[0004] To solve the above problems, the solution proposed by the present invention is: a medical device casting device for muscle stretching and recovery, including an envelope frame A composed of a left plate A and a right plate A with adjustable width, and an envelope frame B composed of a left plate B and a right plate B with adjustable width; further including: a joint gear shaft composed of a joint rotating shaft A and a joint gear A fixedly installed on the joint rotating shaft A, a transmission gear shaft composed of a transmission rotating shaft, a transmission gear A and a transmission gear B fixedly installed on the transmission rotating shaft, a reversing gear shaft composed of a reversing rotating shaft, a reversing gear and a sector gear fixedly installed on the reversing rotating shaft, a power assembly for driving the rotation of the reversing gear shaft, a frame-shaped rack for transmitting the connection between the sector gear and the transmission gear B, a muscle push-pull plate for stretching and retracting the injured muscle, and a muscle push-pull assembly for realizing the transmission connection between the frame-shaped rack and the muscle push-pull plate.

[0005] The joint rotating shaft A rotates through the envelope frame B and is fixedly connected to the envelope frame A, and the transmission gear A meshes with the joint gear A for transmission.

[0006] When the sector gear rotates unidirectionally, the joint gear A rotates forward and backward alternately, and the muscle push-pull plate moves linearly back and forth along the envelope frame B.

[0007] Furthermore, the muscle push-pull assembly includes: an active slider and a passive slider slidably installed on the envelope frame B, and a telescopic spring with both ends fixedly connected to the active slider and the passive slider respectively; the active slider is fixedly connected to the frame-shaped rack, and the passive slider is fixedly connected to the muscle push-pull plate.

[0008] Further, the muscle pushing and pulling plate includes: an arc plate, telescopic rods symmetrically installed on both sides of the arc plate, and an elastic bandage for pressing the arc plate against the injured muscle; the other end of the telescopic rod is fixedly connected to the passive slider.

[0009] Further, the power assembly includes: a motor mount fixedly installed on the envelope frame B, a motor fixedly installed on the motor mount, and a driving gear fixedly installed on the output shaft of the motor; the driving gear meshes and drives with the reversing gear.

[0010] Further, the frame-shaped rack includes: a frame-shaped rack body, and an upper rack and a lower rack respectively fixedly installed on the inner top and inner bottom of the frame-shaped rack body; the driving gear B is eccentrically installed inside the frame-shaped rack and only meshes and drives with the upper rack.

[0011] Further, the joint gear shaft, the driving gear shaft, and the reversing gear shaft are integrally formed by a casting process.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects: The medical device casting device for muscle stretching and recovery of the present invention is provided with a rotatably connected envelope plate B and envelope plate A. By driving the envelope plate B to rotate relative to the envelope plate A by the one-way rotation of the motor, the joints near the injured muscle of the patient can move actively and reciprocally; when the envelope frame A rotates clockwise relative to the envelope frame B, the envelope frame B and the envelope frame A move from the collinear state to the bent state, generating an active retracting force on the injured muscle. At the same time, the muscle pushing and pulling plate moves towards the envelope frame A and generates a passive retracting force on the injured muscle; when the envelope frame A rotates counterclockwise relative to the envelope frame B2, the envelope frame B and the envelope frame A move from the bent state to the collinear state, generating an active stretching force on the injured muscle. At the same time, the muscle pushing and pulling plate moves away from the envelope frame A and generates a passive stretching force on the injured muscle. It can be seen that the present invention is a medical device casting device with a reasonable structure, which can simultaneously generate active and passive stretching and retraction on the injured muscle, and can quickly recover the injured muscle through the dual stretching and retraction functions of the muscle.

Specific implementation mode

[0018] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0019] See Figure 1 and Figure 2 , a medical device casting device for muscle stretching and recovery of the present invention, which includes an envelope frame A1 composed of a left plate A11 and a right plate A12 and with adjustable width, an envelope frame B2 composed of a left plate B21 and a right plate B22 and with adjustable width, a joint gear shaft 4 composed of a joint rotating shaft A41 and a joint gear A42 fixedly installed on the joint rotating shaft A41, a transmission gear shaft 5 composed of a transmission rotating shaft 51, a transmission gear A52 and a transmission gear B53 fixedly installed on the transmission rotating shaft 51, a reversing gear shaft 6 composed of a reversing rotating shaft 61, a reversing gear 62 and a sector gear 63 fixedly installed on the reversing rotating shaft 61, a power assembly for driving the reversing gear shaft 6 to rotate, a frame-shaped rack 8 for transmitting and connecting the sector gear 63 and the transmission gear B53, a muscle push-pull plate 9 for stretching and retracting the injured muscle, and a muscle push-pull assembly for realizing the transmission connection between the frame-shaped rack 8 and the muscle push-pull plate 9. Specifically in implementation, the left plate A11 and the right plate A12 are connected by a telescopic rod, so that the left plate A11 and the right plate A12 can approach or move away from each other; the left plate B21 and the right plate B22 are connected by another telescopic rod, so that the left plate B21 and the right plate B22 can approach or move away from each other. By adjusting the widths of the envelope frame A1 and the envelope frame B2, the moving parts are located outside the patient's limb, making the rehabilitation training patient more comfortable; the frame-shaped rack 8 is slidably installed on the right plate B22 in the envelope frame B2 by a rack frame 81, so that the frame-shaped rack 8 can move horizontally left and right.

[0020] The joint rotating shaft A41 rotates through the envelope frame B2 and is fixedly connected to the envelope frame A1. The transmission gear A52 meshes with the joint gear A42 for transmission. Specifically, when implemented, the joint rotating shaft A41 is rotatably connected to the right side plate B22 by a rolling bearing and passes through the right side plate B22 and is fixedly installed on the right side plate B12. A joint rotating shaft B43 is fixedly installed on the left side plate A11. The joint rotating shaft B43 is rotatably connected to the left side plate B21 by a rolling bearing, and the axis of the joint rotating shaft A41 is collinear with the axis of the joint rotating shaft B43. When the transmission gear shaft 5 rotates counterclockwise, the counterclockwise rotating transmission gear A52 drives the joint gear A42 to rotate clockwise, thereby driving the envelope frame A1 to rotate clockwise relative to the envelope frame B2. When the transmission gear shaft 5 rotates clockwise, the clockwise rotating transmission gear A52 drives the joint gear A42 to rotate counterclockwise, thereby driving the envelope frame A1 to rotate counterclockwise relative to the envelope frame B2.

[0021] When the sector gear 63 rotates unidirectionally, the joint gear A42 rotates forward and backward alternately, and the muscle push-pull plate 9 moves linearly back and forth along the envelope frame B2. The reversing gear shaft 6 rotates clockwise under the drive of the power assembly, and the reversing gear 62 rotates clockwise. When the sector gear 63 meshes with the upper rack in the frame rack 8 for transmission, the frame rack 8 moves horizontally to the right, and then pushes the muscle push-pull plate 9 to move horizontally to the right through the muscle push-pull assembly. When the sector gear 63 meshes with the lower rack in the frame rack 8 for transmission, the frame rack 8 moves horizontally to the left, and then pulls the muscle push-pull plate 9 to move horizontally to the left through the muscle push-pull assembly.

[0022] Preferably, the muscle push-pull assembly includes: a driving slider 31 and a driven slider 33 slidably installed on the envelope frame B2, and a telescopic spring 32 fixedly connected to the driving slider 31 and the driven slider 33 at both ends; the driving slider 31 is fixedly connected to the frame rack 8, and the driven slider 33 is fixedly connected to the muscle push-pull plate 9. Specifically, when implemented, two sets of muscle push-pull assemblies are provided, which are respectively installed on the left side plate B21 and the right side plate B22, and the connection line of the two driving sliders 31 is perpendicular to the movement direction of the driving slider 31.

[0023] Preferably, the muscle push-pull plate 9 includes: an arc-shaped plate 91, telescopic rods 92 symmetrically installed on both sides of the arc-shaped plate 91, and an elastic bandage (not shown in the figure) for pressing the arc-shaped plate 91 against the injured muscle; the other end of the telescopic rod 92 is fixedly connected to the passive slider 33. During specific implementation, one end of each of the two telescopic rods 92 is fixedly connected to the left and right sides of the arc-shaped plate 91 respectively, and the other end is fixedly connected to the two passive sliders 33 respectively; the longitudinal section of the arc-shaped plate 91 along the movement direction is arc-shaped, and the front and rear ends of the arc-shaped plate 91 deviate from the envelope frame B2, which helps to form a pushing and pulling force and a squeezing force on the injured muscle. The two ends of the elastic bandage are respectively connected to the two passive sliders 33, and the middle bypasses the arc-shaped plate 91. The elastic force of the elastic bandage presses the arc-shaped plate 91 near the injured muscle. For example, when the muscle of the calf is injured, the arc-shaped plate 91 is bound under the gastrocnemius muscle, the envelope frame A1 is fixedly installed on the thigh by a flexible rope, and the envelope frame B2 is fixedly installed on the calf by a flexible rope.

[0024] Preferably, the power assembly includes: a motor frame 71 fixedly installed on the envelope frame B2, a motor 72 fixedly installed on the motor frame 71, and a driving gear 73 fixedly installed on the output shaft of the motor 72; the driving gear 73 meshes with and drives the reversing gear 62. The motor 72 drives the driving gear 73 to rotate counterclockwise, and the reversing gear 62 externally meshed with the driving gear 73 rotates clockwise, so that the sector gear 63 on the reversing gear shaft 6 rotates clockwise.

[0025] Preferably, the frame-shaped rack 8 includes: a frame-shaped body, and an upper rack and a lower rack respectively fixedly installed on the inner top and inner bottom of the frame-shaped body; the transmission gear B53 is eccentrically installed inside the frame-shaped rack 8 and only meshes with and drives the upper rack. When the sector gear 63 rotates clockwise and meshes with and drives the upper rack in the frame-shaped rack 8, when the frame-shaped rack 8 moves horizontally to the right, the transmission gear B53 meshing with the upper rack rotates clockwise; when the sector gear 63 meshes with and drives the lower rack in the frame-shaped rack 8, when the frame-shaped rack 8 moves horizontally to the left, the transmission gear B53 meshing with the upper rack rotates counterclockwise; when the sector gear 63 continuously rotates clockwise, the frame-shaped rack 8 moves horizontally to the left and right, and further causes the transmission gear shaft 5 to rotate reciprocally counterclockwise and clockwise.

[0026] Preferably, the joint gear shaft 4, the transmission gear shaft 5, and the reversing gear shaft 6 are integrally formed by a casting process. Since the overall structures of the joint gear shaft 4, the transmission gear shaft 5, and the reversing gear shaft 6 are relatively small, the casting process can be used to improve the structural strength and transmission accuracy of the joint gear shaft 4, the transmission gear shaft 5, and the reversing gear shaft 6.

[0027] The working process of the present invention is as follows: First, the envelope frames A1 and B2 are bound to the patient's limb with elastic bandages. For the convenience of description, it may be considered that the gastrocnemius muscle of the patient's calf is the injured muscle. The envelope frame A1 is fixed on the patient's thigh, and the envelope frame B2 is fixed on the patient's calf. The arc plate 91 is bound under the gastrocnemius muscle, and the position of the joint gear shaft 4 corresponds to the position of the knee joint. The patient's thigh and calf are in a bent state. The motor 72 rotates counterclockwise, driving the reversing gear 62 to rotate clockwise; when the sector gear 63 meshes with the upper rack for transmission, the frame-shaped rack 8 moves horizontally to the right, and the transmission gear shaft 5 rotates clockwise, thereby driving the joint gear shaft 4 and the envelope frame A1 to rotate counterclockwise relative to the envelope frame B2, realizing the movement of the calf and thigh from the bent state to the collinear state; at the same time, the frame-shaped rack 8 moving horizontally to the right pushes the active slider 31 to move horizontally to the right, and then through the spring pressure generated by the telescopic spring 32, pushes the passive slider 33 and the muscle push-pull plate 9 to move to the right, so that the arc plate 91 in the muscle push-pull plate 9 generates a passive stretching movement on the injured muscle. When the sector gear 63 meshes with the lower rack for transmission, the frame-shaped rack 8 moves horizontally to the left, and the transmission gear shaft 5 rotates counterclockwise, thereby driving the joint gear shaft 4 and the envelope frame A1 to rotate clockwise relative to the envelope frame B2, realizing the movement of the calf and thigh from the collinear state to the bent state; at the same time, the frame-shaped rack 8 moves horizontally to the left, pulling the active slider 31 to move horizontally to the left, and then through the spring tension generated by the telescopic spring 32, pulling the passive slider 33 and the muscle push-pull plate 9 to move to the left, so that the arc plate 91 in the muscle push-pull plate 9 generates a passive retracting movement on the injured muscle.

[0028] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should fall within the protection scope of the present invention.
