[0027] The person being examined (patient) passes his calf and foot through the fixed plate 602 and the mounting plate 4, and then extends his foot between the pressing plate 506 and the movable plate 502. The position of the fixed plate 602 can be moved by the fixing assembly 6, and the device is clamped on the patient's leg. Then, the handle 508 is turned to drive the screw 507 to rotate, thereby driving the pressing plate 506 to move toward the sole of the patient's foot, and the pressing plate 506 is fit against the sole of the patient's foot to complete the wearing of the device.
[0028] See also Figures 1 to 3 , the rotating shaft 501 is fixedly connected to one end of the mounting plate 4, the movable plate 502 is rotatably connected to the surface of the rotating shaft 501, the pointer 503 is fixedly connected to one side of the movable plate 502, the extension plate 504 is fixedly connected to one side of the movable plate 502, the fixed rod 505 is fixedly connected to one side of the movable plate 502, the pressing plate 506 is slidably connected to the surface of the fixed rod 505, the pressing plate 506 is threadedly connected to the surface of the screw 507, the screw 507 is rotatably connected to one side of the movable plate 502, the turning handle 508 is fixedly connected to one end of the screw 507, one end of the extension plate 504 passes through the groove 2, and the fixed rod 505, the screw 507, and the turning handle 508 are all located on the outside of the semicircular housing 1;
[0029] When measuring after the device is worn, the initial position of the pointer 503 pointing to the scale 3 is first recorded. When the patient performs dorsiflexion or plantar flexion, the movable plate 502 can be driven to rotate during the movement, and the pointer 503 can be driven to move at the same time, so that the pointer 503 points to the new position of the scale 3. The angle formed by the two positions is the angle of the patient's dorsiflexion or plantar flexion movement.
[0030] See also Figures 1 to 5A fixing assembly 6 is provided at the bottom of the mounting plate 4. The fixing assembly 6 includes a connecting rod 601, a fixing plate 602, a protective cushion 603, a threaded portion 604, and a connecting sleeve 605. Connecting rods 601 are installed at the four corners of the bottom of the mounting plate 4. The surface of the connecting rod 601 is slidably connected to the fixing plate 602. The top of the fixing plate 602 is fixedly connected to the protective cushion 603. A threaded portion 604 is provided on the surface of one of the connecting rods 601. The surface of the threaded portion 604 is threadedly connected to the connecting sleeve 605. The outer surface of the connecting sleeve 605 is rotatably connected to the fixing plate 602. An arc groove is provided on the top of the protective cushion 603. The material of the protective cushion 603 is a nylon pad.
[0031] The person being examined (patient) passes his calf and foot through the fixing plate 602 and the mounting plate 4, and rotates the connecting sleeve 605 according to the leg circumference of the patient's calf, which can drive the fixing plate 602 to move upward, and at the same time drive the protective cushion 603 to move upward, clamp the patient's calf, and fix the device on the patient's leg, which can adapt to the leg circumference of different patients.
[0032] In the present invention, the working principle of the device is as follows:
[0033] When in use, the person being examined (patient) passes the calf and foot between the fixing plate 602 and the mounting plate 4, and then extends the foot between the pressing plate 506 and the movable plate 502. The medical staff then rotates the connecting sleeve 605 according to the leg circumference of the patient's calf, which can drive the fixing plate 602 to move upward, and at the same time drive the protective cushion 603 to move upward, clamp the patient's calf, and fix the device on the patient's leg. The device can adapt to the leg circumference of different patients and improve flexibility. At the same time, the patient's leg can be protected by the protective cushion 603. After the leg is fixed, the handle 508 is rotated to drive the screw 507 to rotate, thereby driving the pressing plate 506 to move toward the sole of the patient's foot, and the pressing plate 506 is fitted with the sole of the patient's foot to complete the wearing of the device.
[0034] During measurement, first record the initial position of the pointer 503 pointing to the scale 3. When the patient performs dorsiflexion or plantar flexion, the movable plate 502 can be driven to rotate during the movement, and the pointer 503 can be driven to move at the same time, so that the pointer 503 points to the new position of the scale 3. The angle formed by the two positions is the angle of the patient's dorsiflexion or plantar flexion movement. Compared with the traditional angle gauge measurement, the device has the advantages of high angle measurement accuracy, more precise measurement position and short measurement time.
