[0018] Preferably, the method of use is as follows:

[0019] A. When the device is needed to massage the knee joint, first place the thigh inside the base frame. The soft cushion can improve the user experience at this time. After placement, push the push block backwards. The push block drives the movable block to move backwards in the inner cavity of the base frame. The movable block will squeeze the spring and deform the spring when moving until the positioning column is completely moved into the inner cavity of the base frame. Then, pick up the installation cover through the handle on the top of the installation cover, insert the two sides of the bottom of the installation cover into the inner cavity of the installation slot, and release the push block after the insertion is complete. At this time, the pressure on the spring disappears and resets.

[0020] B. When massage is needed, first start the infrared lamp of the infrared irradiation unit to heat the knee area. The infrared lamp uses the thermal effect of infrared wavelengths. Local heating of tissues can promote tissue healing and reduce inflammatory reactions. Then, the dual-axis motor can be started. With the cooperation of the active wheel and the driven wheel, the two rotating columns can be made to rotate synchronously with the output shaft of the dual-axis motor. When the rotating columns rotate, they can drive the fixed sleeve, the massage block and the soft sleeve to rotate.

The servo motor a can also be started to drive the threaded rod to rotate. When the threaded rod rotates, the position of the left support sleeve can be adjusted so that it can drive the components between the two support sleeves to move synchronously. The servo motor a rotates back and forth continuously, which can drive the massage block and the soft sleeve to move back and forth, so that the massage block and the soft sleeve can perform rolling massage on the knee area. Two massage methods are available for users to choose, thereby improving the practicality of the device.

[0021] C. When knee joint exercise is required, the base frame is placed on the bed, and the patient is in a sitting position. The connection between the base frame and the leg rest should be placed on the edge of the bed, and the leg rest is located outside the bed to reserve space for the flexion and extension of the leg rest. The thigh is placed inside the base frame, with the knee fixed under the mounting cover as the axis. The patient places the calf on the leg rest, and the airbag is inflated to wrap the patient's calf to prevent it from slipping during exercise. At the same time, it can adapt to the different leg circumferences of different patients, and the inflated airbag also has a pressurization function, which can relieve local muscle edema and promote the absorption of aseptic inflammation. For inflation and exhaust of the airbag, air is sucked in from the external environment through an air pump and connected to the airbag through a pipe. When exhausting, the air pump stops working and releases the air inside the airbag through an electric valve or a mechanical valve. After the above preparations are completed, the servo motor is started, and the output shaft of the servo motor is driven by The movable rotating rod and the gear rotate, and the gear meshes with the toothed plate. The toothed plate will drive the round rod to move to the right under the rotation of the gear, and the round rod drives the limiting pulley to move, and the limiting pulley moves to the right in the limiting slideway opened at the bottom of the triangular plate. Since the limiting slideway at the bottom of the triangular plate is opened in an upward oblique direction, the leg support and the base frame are connected by a pin, which is not only convenient for disassembly, but also the pin can be used as an axis to adjust the angle of the leg support while the limiting pulley moves to the right. The servo motor can also be used to drive the round rod and the limiting pulley to realize left and right reciprocating telescopic movement to realize the flexion and extension movement of the calf. The flexion and extension speed can be achieved by adjusting the rotation speed to promote the increase of the range of motion of the knee joint. It is used for rehabilitation training of patients after tibial plateau surgery, arthroscopic surgery after cruciate ligament injury and meniscus injury of the knee, femoral condyle fracture, unicompartmental knee replacement or total knee replacement.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention wraps the patient's calf by inflating the airbag to adapt to the different leg circumferences of different patients, and the inflated airbag also has a pressurizing function, which can relieve local muscle edema and promote the absorption of aseptic inflammation. The servo motor, the rotating rod and the gear are started to cooperate, and the limiting pulley moves to the right in the limiting slideway opened at the bottom of the triangle plate, and the angle of the leg rest is adjusted. The flexion and extension angle and the flexion and extension speed are adjusted by the forward and reverse rotation of the servo motor and the adjustment of the rotation speed to promote the increase of the knee joint activity, which is beneficial to the rehabilitation training of patients after tibial plateau surgery, arthroscopic surgery after cruciate ligament injury and meniscus injury of the knee, femoral condyle fracture, unicompartmental knee replacement or total knee replacement.

When the device is needed to massage the knee joint, the thigh is first placed inside the base frame (1). The soft cushion (2) can improve the user experience at this time. After the placement is completed, the push block (405) is pushed backward. The push block (405) drives the movable block (402) to move backward in the inner cavity of the base frame (1). When the movable block (402) moves, it squeezes the spring (406) and causes the spring (406) to deform until the positioning column (403) is completely moved into the inner cavity of the base frame (1). Then, the positioning column (403) is moved backward. The mounting cover (3) is picked up by the handle on the top of the mounting cover (3), and the two sides of the bottom of the mounting cover (3) are inserted into the inner cavity of the mounting groove (401). After the insertion is completed, the push block (405) is released, and the pressure on the spring (406) disappears and resets.

When massage is required, firstly, the infrared lamp of the infrared irradiation unit (5) is started to heat the knee area. The infrared lamp utilizes the heat effect of infrared wavelengths. Local heating of tissues can promote tissue healing and reduce inflammatory reactions. Then, the dual-axis motor (605) can be started. With the cooperation of the driving wheel (606) and the driven wheel (607), the two rotating columns (601) can be made to rotate synchronously with the output shaft of the dual-axis motor (605). When the rotating column (601) rotates, it can drive the fixed sleeve (602), the massage block (603) and the soft sleeve (604) to rotate. When the massage block (603) and the soft sleeve (604) rotate, they can circulate. The patient's joints are pressed and massaged regularly to achieve the purpose of rehabilitation. The servo motor a (611) can also be started to drive the threaded rod (609) to rotate. When the threaded rod (609) rotates, the position of the left support sleeve (608) can be adjusted, so that it can drive the components between the two support sleeves (608) to move synchronously. The servo motor a (611) continuously rotates back and forth, which can drive the massage block (603) and the soft sleeve (604) to move back and forth, so that the massage block (603) and the soft sleeve (604) can perform rolling massage on the knee. Two massage methods are available for users to choose. C. When knee joint exercise is required, the base frame (1) is placed on the bed, the patient is in a sitting position, the connection between the base frame (1) and the leg support (71) should be placed at the edge of the bed, the leg support (71) is located outside the bed, and space is reserved for the flexion and extension of the leg support (71). The thigh is placed inside the base frame (1), with the knee fixed under the mounting cover (3) as the axis, the patient places the calf on the leg support (71), the airbag (711) is inflated to wrap the patient's calf to prevent it from slipping during exercise, and at the same time, it can adapt to the different leg circumferences of different patients. The inflated airbag (711) also has a pressurizing function, which can relieve local muscle edema and promote the absorption of aseptic inflammation. The inflation and deflation of the airbag (711) are performed by sucking air from the external environment through an air pump, which is connected to the airbag (711) through a pipeline. When deflation is performed, the air pump stops working and releases the air inside the airbag (711) through an electric valve or a mechanical valve. After the above preparations are completed, the servo motor (725) is started, and the output shaft of the servo motor (725) drives the rotating rod (724) and the gear (723) to rotate. The gear (723) meshes with the toothed plate (720), and the toothed plate (720) drives the round rod (721) to move to the right under the rotation of the gear (723), and the round rod (721) drives the limiting pulley (722) to move, and the limiting pulley (722) moves to the right in the limiting slideway provided at the bottom of the triangular plate (712). Since the limiting slideway at the bottom of the triangular plate (712) is provided in an oblique upward direction, the leg support (71) and the bottom frame (1) are connected by a pin, which is not only convenient for disassembly, but also the pin can be used as an axis to move the limiting pulley (722) to the right. While moving to the right, the angle of the leg support (71) is adjusted. The servo motor (725) can also be rotated forward and backward to drive the round rod (721) and the limit pulley (722) to realize left and right reciprocating telescopic movement, thereby realizing flexion and extension movement of the calf. The flexion and extension speed can be achieved by adjusting the rotation speed to promote the increase of the range of motion of the knee joint, and the flexion and extension angle can be adjusted. It is used for rehabilitation training of patients after tibial plateau surgery, arthroscopic surgery after cruciate ligament injury and meniscus injury of the knee, femoral condyle fracture, unicompartmental knee replacement or total knee replacement.
