[0002] In recent years, with the accelerated pace of life and changes in eye habits, dry eye has become a common eye disease, with meibomian gland dysfunction being the most common cause. The most common symptom of meibomian gland dysfunction is obstruction of the meibomian glands, which prevents normal secretion of meibomian fat. Traditional treatments for meibomian gland obstruction generally include physical heat compresses and massage, Chinese herbal fumigation, massage, intense pulsed light (IPL), and thermal pulse therapy. However, heat compresses and massage require long-term adherence and may not be effective in the short term. Improper self-massage can also affect the effectiveness. Medication can cause side effects, while surgery carries risks and complications, along with a prolonged recovery period and the need for patient care. While intense pulsed light therapy significantly improves the patient experience and alleviates pain, it can still cause some discomfort during treatment. Thermal pulse therapy is relatively expensive and burdensome for patients. Therefore, there is a need for a new device to alleviate or treat dry eye caused by meibomian gland obstruction.

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below with reference to 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. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to 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, for clamping the eyelid and forming an eyeball position for accommodating the eyeball;

[0032] A heating component 20 is used to perform radiofrequency heating on the eyelids to melt meibum in the meibomian glands;

[0033] The pulsed 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 squeeze the meibomian glands, thereby expelling meibomian fat.

[0034] The heating assembly 20 is used to heat the meibomian glands, converting the blocked meibomian fat from a solid state into a fluid, easily excreted oil. The pulsed electrical stimulation assembly 30 can stimulate the orbicularis oculi muscle to spontaneously contract using a current signal (e.g., a nanoampere current signal). Multiple electrical stimulation assemblies can be provided, distributed around the orbicularis oculi muscle. After the meibomian fat regains its fluidity due to heating, the orbicularis oculi muscle is electrically stimulated, causing the orbicularis oculi muscle to reflexively twitch the eyelids. This twitching exerts pressure on the meibomian glands, which promotes the smooth excretion of the restored fluidity of the meibomian fat.

[0035] The treatment head clamps the eyelid to be treated through the eyelid clamping mechanism, and then heats the eyelid through the heating component, and uses electricity to stimulate the orbicularis oculi muscle area to cause a conditioned reflex. Combined with the physiological structure characteristics of the eyelid itself (the orbicularis oculi muscle can drive the eyelid to move when it moves), it produces natural squeezing of the meibomian gland. There is no need to set up a special external force squeezing structure. The structure is simpler, easier to implement, and the cost is lower. In addition, external mechanical squeezing can easily damage the meibomian gland, and the patient feels strong discomfort. The treatment process of this treatment head is safer, and the meibomian gland is less likely to be damaged due to excessive squeezing. At the same time, it can greatly reduce the patient's pain, which is one of the innovations of the present invention.

[0036] See also Figure 2The orbicularis oculi muscle is a circular muscle located around the eye socket. When it contracts, it exerts pressure on the meibomian glands, which helps promote the secretion and drainage of meibum. Meibomian is a grease secreted by the meibomian glands that plays an important role in maintaining ocular lubrication and preventing excessive tear evaporation. When the meibomian glands function normally, meibum is evenly coated on the surface of the eyeball, forming 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] Radiofrequency heating offers the advantages of uniform, rapid heating of the entire eyelid. Compared to traditional external hot towel compresses, radiofrequency heating technology can directly generate an electromagnetic heat source within the eyelid, eliminating the need for heat conduction from the outside to the inside. This allows for faster heating and reduces the risk of heat loss during conduction. This improves the heating effect on the meibomian glands within the eyelid, a key innovation of the present invention. In some implementations, the radiofrequency generator may include a radiofrequency current generator and a radiofrequency control circuit. Radiofrequency heating using a radiofrequency generator is conventional technology, and those skilled in the art can freely design their own designs as needed. This present invention does not involve improvements to the radiofrequency current generator and radiofrequency control circuit, and will not be elaborated upon.

[0039] In one implementation, an electrode 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, the most appropriate frequency for regulating the activity of ions inside and outside cells, to heat the inside and outside of the eyelid as a whole, so that it is evenly heated. The heating method is more scientific, safe and efficient.

[0040] According to one embodiment of the present invention, the pulse electrical stimulation component includes a pulse generating device and an electrical stimulation electrode connected to each other, the pulse generating device is used to output electrical pulses; the electrical stimulation electrode is connected to the pulse generating device, and is used to apply the electrical pulses to the orbicularis oculi muscle area for electrical stimulation.

[0041] According to one embodiment of the present invention, the pulse generating device is a pulse generator, and at least one electrical stimulation protrusion is provided on the surface of the electrical stimulation electrode on one side close to the orbicularis oculi muscle area.

[0042] According to one embodiment of the present invention, the pulse generator is a multi-channel, multi-contact pulse generator, and the plurality of electrical stimulation electrodes are connected to the multi-channel, multi-contact pulse generator via contacts of extension wires. The plurality of electrical stimulation electrodes are arranged according to the distribution of the orbicularis oculi muscle.

[0043] In one implementation, electrical stimulation and electric heating are independently provided, and a metal sheet is attached to the surface of the electric heating plate. The surface of the electric heating plate is insulated, and heating is performed by generating a magnetic field, and electrical stimulation is performed through the metal sheet on its surface.

[0044] See also Figure 3 and Figure 4 According to one embodiment of the present invention, the treatment head further comprises: a first base body 40 and a second base body 50;

[0046] In order to protect the eyeball, a heat-insulating protective layer 403 is provided on the outer surface 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 not overlapped. 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 with 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 closely to the eyelid without causing discomfort.
