The most common symptom of meibomian gland dysfunction is meibomian gland obstruction, which prevents the normal discharge of meibomian fat. Traditional treatments for meibomian gland obstruction generally include physical hot compress massage, Chinese medicine fumigation, massage, intense pulsed light, thermal pulsation, etc. However, hot compress and massage require long-term persistence, and the effect may not be obvious in the short term. Improper operation of patients when massaging themselves will also affect the effect. Drug treatment may have side effects, surgical treatment has certain risks, and may also cause complications, and the postoperative recovery time is long, requiring patient care. Intense pulsed light therapy greatly improves the patient's treatment experience and greatly reduces the patient's pain, but a certain degree of discomfort may still occur during the treatment process, and the cost of thermal pulsation treatment is relatively high, and the patient's burden is heavy.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and therefore, the present invention is not limited to the limitations of the specific embodiments disclosed below.

[0030] like Figure 1 As shown, according to one embodiment of the present invention, a treatment head 1 for alleviating or treating meibomian gland obstruction is disclosed, comprising:

[0031] An eyelid clamping mechanism 10, used for clamping the eyelid and forming an eyeball position for accommodating the eyeball;

[0032] A heating component 20, used for performing radio frequency heating on the eyelids to melt the meibomian glands;

[0033] The pulse electrical stimulation component 30 is used to stimulate the orbicularis oculi muscle so that the orbicularis oculi muscle automatically contracts after being electrically stimulated, thereby driving the eyelids to twitch, and then squeezing the meibomian glands to discharge meibomian fat.

[0034] The heating component 20 is used to heat the meibomian glands so that the blocked meibomian fat is converted from a solid state to a fluid fat that is easy to discharge; the pulsed electrical stimulation component 30 can stimulate the orbicularis oculi muscle to contract autonomously through a current signal (for example, a nanoampere current signal), and the electrical stimulation component can be provided in multiple numbers, which are distributed around the orbicularis oculi muscle. After the meibomian fat is heated to restore its fluidity, the orbicularis oculi muscle area of ​​the eye is electrically stimulated, and the orbicularis oculi muscle conditioned reflex drives the eyelid to twitch, and when the eyelid twitches, a certain pressure is generated on the meibomian glands, and this pressure can promote the smooth discharge of the meibomian fat that has restored its fluidity.

[0035] The treatment head clamps the eyelid to be treated by an eyelid clamping mechanism, and then heats the eyelid by a heating component, and uses electrical stimulation to stimulate the orbicularis oculi muscle area to cause a conditioned reflex, thereby generating natural squeezing of the meibomian gland in combination with the physiological structure characteristics of the eyelid itself (the orbicularis oculi muscle can drive the eyelid to move when it moves), without the need to set up a special external force squeezing structure, the structure is simpler, easier to implement, and the cost is also lower. In addition, external mechanical squeezing can easily damage the meibomian glands, causing strong discomfort to the patients. The treatment process of the treatment head is safer, and the meibomian glands are less likely to be damaged due to excessive squeezing. At the same time, it can also greatly reduce the pain of the patients, which is one of the innovative points of the present invention.

[0036] See also Figure 2The orbicularis oculi muscle is a circular muscle located around the eye socket. When the orbicularis oculi muscle contracts, it can exert a certain amount of pressure on the meibomian glands, which helps promote the secretion and discharge of meibum in the meibomian glands. Meibomian is a kind of oily substance secreted by the meibomian glands, which plays an important role in maintaining the lubrication of the eye surface and preventing excessive evaporation of tears. When the meibomian glands function normally, meibomian can be evenly coated on the surface of the eyeball to form a protective oil film.

[0037] According to one embodiment of the present invention, the heating assembly includes heating electrode sheets arranged in pairs for contacting the outer surface of the eyelid and the inner surface of the eyelid respectively, and a radio frequency generating device for connecting to the two heating electrode sheets.

[0038] Radio frequency heating has the advantages of uniform and rapid heating of the whole body. Compared with the traditional external hot towel for hot compressing the eyes, radio frequency heating technology can directly generate an electromagnetic heat source inside the eyelid, without the need for heat conduction from the outside to the inside, and the heating is faster. The heat is not easily lost during the conduction process, and the heating effect on the meibomian glands inside the eyelid is better, which is one of the innovations of the present invention. In some implementations, the radio frequency generating device may include a radio frequency current generator and a radio frequency control circuit. The radio frequency generating device for radio frequency heating is a prior art, and those skilled in the art can freely design it according to their needs. The present invention does not involve improvements to the radio frequency current generator and the radio frequency control circuit, and will not be repeated.

[0039] In one implementation, an electrode sheet is set inside and outside the eyelid, and the eyelid is used as a resistor (load). The two electrode sheets are respectively connected to the output end of the power supply, and high-frequency radio frequency heating is applied to the eyelid. The frequency uses 448khz high-frequency radio frequency, which is the most appropriate frequency for regulating the activity of ions inside and outside the cells. The inside and outside of the eyelid are heated as a whole to make it evenly heated. The heating method is more scientific, safe and efficient.

[0046] In order to protect the eyeball, a heat-insulating protective layer 403 is provided on the outer surface of one side of the first substrate close to the eyeball, the heating electrode sheets 201 are arranged in pairs, and are respectively arranged on the first substrate and the two second substrates, the electric stimulation electrodes are arranged on the second substrates, and the electric stimulation electrodes 301 and the heating electrode sheets are arranged without overlapping. When the upper and lower eyelids enter the clamping gap and are clamped by the first substrate and the second substrate, the heating electrode sheet can contact and fit the eyelids, and the electric stimulation electrode can contact the orbicularis oculi muscle area. In some implementations, the electrode sheet is made of a material with good biocompatibility, such as medical stainless steel or carbon fiber. The shape and size of the electrode sheet are designed according to the physiological structure of the eyelid to ensure that it can fit the eyelids tightly without causing discomfort.
