Description

Technical Field

[0001] This utility model relates to the field of wearable devices, and more particularly to a wearable device for shape and position capture. Background Technology

[0002] The knee joint is an important weight-bearing joint in the human body. Osteoarthritis of the knee, which eventually occurs due to knee joint injury and degeneration, is one of the most common disabling diseases in the elderly worldwide. Epidemiological studies show that with the acceleration of population aging, knee osteoarthritis (KOA) will bring long-term economic and physical burdens to more than half of Chinese families. The clinical manifestations of this disease are pain when bearing weight and walking, which is relieved after rest. In the end stage, patients will become disabled due to pain, which will seriously affect the physical and mental health of the patients and their families.

[0003] Knee replacement surgery requires extremely precise osteotomy distances and angles. It is generally believed that the allowable error in the postoperative lower limb force line is ±3°. Therefore, accurate measurement of the force line has a significant impact on the surgical outcome. The vigorous development of existing technologies, including mechanical positioning, navigation positioning, and robot-assisted technology, has further improved surgical precision, but none of them can obtain real-time dynamic force line assessment, thus failing to achieve better surgical assistance and surgical results.

[0004] To address this issue, a wearable device for shape and position capture is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-3 An embodiment of this utility model is provided: a wearable device for shape and position capture, including a tight-fitting inner layer 1 and a tight-fitting outer layer 2, which improves high temperature resistance. The tight-fitting outer layer 2 is fixedly connected to the surface of the tight-fitting inner layer 1. A sock 8 is provided at the bottom of the tight-fitting inner layer 1. The sock 8, the tight-fitting inner layer 1 and the tight-fitting outer layer 2 are all made of spandex material. A transmission device 3 is fixedly connected to the top of the front of the tight-fitting outer layer 2.

[0030] The transmission device 3 includes a processor 31. The input terminal of the processor 31 is electrically connected to a bending sensing module 32, an electromyography (EMG) sensing module 33, and a power supply module 34. The power supply module 34 is a lithium-ion battery. By setting the power supply module 34 as a lithium-ion battery, it can supply power to the bending sensing module 32 and the EMG sensing module 33. It can also be charged by magnetic charging technology. The bending sensing module 32 is a bending sensor, and the EMG sensing module 33 is a surface electromyography (SEMG) sensor. By setting the bending module 32 as a bending sensor, data such as the bending angle and bending speed of muscles can be extracted, providing key information for constructing a human body model. The output terminal of the processor 31 is electrically connected to a wireless communication module 35.

[0031] The output of wireless communication module 35 is electrically connected to wireless communication module 4. Both wireless communication module 35 and wireless communication module 4 are wireless communication modules. By setting wireless communication module 35 and wireless communication module 4, data can be transmitted wirelessly. The output of wireless communication module 4 is electrically connected to host 5. Host 5 is equipped with human body model construction software. The output of host 5 is electrically connected to display 6. Host 5 is a computer host 5, and display 6 is an LCD screen. By setting display 6 to an LCD screen, it is convenient for users to observe the data.

[0032] Reference Figure 1 An elastic band 7 is fixedly connected to the top of the outer layer 2 of the leggings. A bending sensor module 32 is fixedly connected to the inside of the inner layer 1 of the leggings and the right side of the sock 8. An electromyography sensor module 33 is fixedly connected to the inside of the inner layer 1 of the leggings and the sock 8. By using the elastic band 7, the top of the outer layer 2 of the leggings can be tightened to prevent the inner layer 1 of the leggings from falling off, thus improving the stability of the inner layer 1 of the leggings.

[0033] Working principle: When in use, the user first puts the inner layer 1 of the compression pants on the patient's hip joint and the socks 8 on the patient's ankle joint. When the patient makes a movement, the electromyography (EMG) sensing module 33 obtains data on muscle contraction and relaxation by monitoring the electrical activity on the muscle surface. The flexion sensing module 32 can obtain data such as joint flexion angle and flexion speed. The processor 31 sends the data to the host 5 through the wireless communication module 1 35 and the wireless communication module 2 4. The host 5 sends the data to the software. The software constructs a human body model based on the position information of the numerous EMG sensing modules 33 and the flexion sensing module 32. This model can simulate the human muscle morphology, predict the human body's movement posture and force output, and facilitate doctors to understand the patient's lower limb force line, thereby achieving the advantage of obtaining dynamic force line assessment in real time.
