Problems solved by technology

However, due to the complex distribution and functions of facial muscles, the myoelectric signals and nerve signals are many and interfere with each other, and in many cases, the myoelectric and nerve signals are not necessarily consistent with the movement of muscles or faces, resulting in the uncertainty of signal extraction The uncontrollability of sex and electrical stimulation, therefore, there is still a lot of research to be done on this method before clinical application

Embodiment 1

[0030] like figure 1 As shown, Embodiment 1 of the present invention provides a micromechanical system for treating unilateral eyelid closure disorder, including an information collection device 1, a micromechanical device 2 and a terminal processor 3,

[0031] The information collection device 1 is embedded in the eyelid of the healthy side or installed on a device worn outside the body, and is used to collect the opening and closing of the eyelid of the healthy side and send it to the terminal processor 3;

[0032] The micromechanical device 2 is embedded in the eyelid of the affected side, and is used to control the opening and closing of the eyelid of the affected side according to the opening and closing of the eyelid of the affected side;

[0033] The terminal processor 3 is embedded in the body or installed on a wearable device outside the body, and is used to receive the data collected by the information collection device 1, and send the data to the micromechanical dev...

Embodiment 2

[0037] On the basis of Embodiment 1, this Embodiment 2 provides a micromechanical system for treating unilateral eyelid closure disorder. This Embodiment 2 further defines that the terminal processor 3 communicates with the micromechanical Device 2 is connected.

[0038] The instruction of the micromechanical movement comes from the terminal processor 3 . The terminal processor 3 is connected with the micromachines through microelectrodes or wireless signals or other signal transmission systems. After receiving the eye movement signal from the healthy side, the terminal processor 3 starts to issue instructions (electrical stimulation or magnetic stimulation and other stimulations), and then guides the movement of the micromachine.

[0039] The information collection device 1 is a sensing device embedded in the eyelid of the affected side, or a camera mounted on an externally worn device for collecting moving images of the healthy side's eyelid; the externally worn device can ...

Embodiment 3

[0042] On the basis of Example 1, this Example 3 provides a micromechanical system for treating unilateral eyelid closure disorder. This Example 3 further defines that when the information collection device 1 is embedded in the affected eyelid When using a sensing device, the terminal processor 3 converts the angle information into a digital signal and transmits it to the micromechanical device 2 according to the opening and closing angle of the uninjured eyelid acquired by the sensing device. The micromechanical device 2 controls the eyelid on the affected side to open and close at an angle consistent with the eyelid on the unaffected side according to the signal.

Abstract

The present invention provides a system for micromechanical treatment of unilateral eyelid closure disorder, which acquires the opening and closing angle of the uninjured eyelid through an information collection device and sends it to a terminal processor; the terminal processor processes the angle information and The signal is transmitted to the micro-mechanical device, instructing the micro-mechanical device to drive the eyelid on the affected side to move, so that the eyelid on the affected side and the eyelid on the healthy side can complete symmetrical movements at the same angle. Thus, the problem of unilateral eyelid closure disorder is solved. Information collection device. The information collection self-device and terminal processor can be embedded in the human body, or can be set on an external wearable device, which can be used in various ways and is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of micro-mechanics, in particular to a micro-mechanical system for treating unilateral eyelid closure disorder. Background technique [0002] Many reasons in life can cause eyelid closure disorder, the most common factor is facial paralysis caused by various reasons, including idiopathic facial paralysis, facial paralysis caused by trauma and so on. In Western Europe and the United States, the incidence rate of facial paralysis is about 20 to 35 / 100,000 residents, and the incidence rate of facial paralysis in my country is higher. It can be seen that eyelid closure disorder is a common disease. Due to the closure of the eyelids, the patient cannot close the eyes normally. On the one hand, this causes the facial deformity of the patient. On the other hand, the eyeball and cornea cannot be effectively protected due to the inability of the eyelids to close, which can cause serious ocular complications. . [...
