Description

Technical Field

[0001] The utility model relates to the technical field of meibomian gland conduction, in particular to a radiofrequency therapeutic device for meibomian gland dysfunction and dry eyes. Background Art

[0002] Dry eye disease (DED) is the most common ocular surface disease, characterized by symptoms such as dryness, stinging, burning, and foreign body sensation. It can also be accompanied by ocular surface inflammation, tissue damage, and neurological abnormalities. DED is a chronic eye disease, and repeated attacks can severely impact patients' daily lives, reducing work efficiency and quality of life. The prevalence of dry eye in my country is approximately 21-30%, and the number of dry eye patients in China is approximately 360 million. This large patient base imposes a heavy social and economic burden.

[0003] Currently, the treatments for dry eyes mainly include drug therapy and physical therapy. Among them, physical heat therapy is the basis for treating dry eyes. It improves gland function by heating the eyelids, improving or eliminating meibomian gland duct obstruction, and thus restoring the normal microenvironment of the ocular surface.

[0004] Among these, heat therapy is a common treatment method. This involves applying heat to the eyelids using a hot eye mask or a heating device, melting the abnormal meibum clogged in the meibomian glands and promoting its excretion through the meibomian gland openings, thereby treating dry eyes. However, this heat conduction method suffers from slow heat transfer, heat loss during conduction, and insufficient heating depth, resulting in poor treatment effectiveness. Utility Model Content

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0051] See also Figure 1-13 The embodiment of the present invention provides a radiofrequency therapeutic device for meibomian gland dysfunction and dry eyes, comprising an operating handle 1 and a main body 2.

[0052] The operating handle 1 includes a handle 11 and a radio frequency head 12. The radio frequency end of the radio frequency head 12 is provided with at least two electrodes 121, with an insulator 122 between adjacent electrodes 121. The connecting end of the radio frequency head 12 is connected to the handle 11. The electrodes 121 are capable of generating radio frequency current (i.e., high-frequency alternating current electromagnetic waves).

[0053] When in use, hold the operating handle 1 and press the RF end of the RF head 12 against the outside of the patient's eyelid. The electrode 121 on the RF head 12 applies RF current to the eyelid, which promotes polar molecules in the eyelid tissue (that is, the centers of positive and negative charges in the molecules do not overlap, resulting in polarity caused by uneven distribution of charges), such as polar water molecules and other charged ions to oscillate, and the friction between the charged ions generates heat energy to achieve heating of the eyelid, thereby melting the abnormal meibum blocked in the meibomian gland, and promoting the discharge of meibum from the opening of the meibomian gland, thereby achieving the purpose of treating dry eyes. Compared with the method of heating the eyelids with a heater, radiofrequency current is applied to the eyelids, directly acting on the eyelid tissue, and heat is generated by the charged ions in the eyelid tissue. The heat conduction speed is fast, there is no heat loss in heat conduction, and the volume of the meibomian glands deep in the eyelids is directly heated, thereby improving the thermal therapy effect. At the same time, radiofrequency current also has a non-thermal effect. By changing the cell physiological signaling pathway, it triggers intracellular and intercellular metabolism, activates transport proteins, increases intracellular calcium ion concentration, activates intracellular calcium channel-dependent metabolic pathways, and at the same time downregulates the expression levels of proteases and inflammatory factors such as matrix metalloproteinase-9 (MMP-9), further improving the treatment effect of dry eye.

[0054] Furthermore, at least two electrodes 121 are provided at the RF end of the RF head 12, and the two electrodes 121 simultaneously apply RF current to different positions of the eyelid, thereby improving the uniformity of the application of RF current, thereby uniformly heating the entire meibomian gland of the eyelid and improving the dry eye treatment effect.

[0055] Furthermore, any two electrodes 121 among the at least two electrodes 121 are respectively a positive electrode and a negative electrode.

[0056] Any two of the at least two electrodes 121 alternately exchange positive and negative charges to form a positive and negative pole. When in contact with the eyelids, the two electrodes 121 form a closed circuit, creating multiple current loops at the RF end and concentrating the current energy used for treatment. Therefore, electrodes 121 operating at lower power and voltage can provide sufficient energy to the eyelids, rapidly raising the temperature of the eyelid tissue in the treatment area, effectively shortening the time required to heat the eyelids to the required temperature for dry eye hyperthermia therapy, and subjecting the eyelids to a lower voltage, ensuring treatment safety and improving patient comfort.

[0057] In comparison, if only one electrode 121 is provided on the RF head 12, an additional electrode pad that fits the patient's body is required to form a closed loop with the single electrode 121 on the RF head 12. This places high demands on the patient's body position and increases the difficulty of operation. Moreover, since the power of the monopolar RF must be set higher, the power density at the point where the RF head fits the eyelid is also higher, which can easily cause overheating and lead to local burns and stinging of the eyelid. The present application increases the number of electrodes 121, which can enable any two electrodes 121 on the RF head 12 to form a closed loop after contacting the eyelid, reducing the requirements on the patient's body position and facilitating operation. Moreover, the power of each electrode 121 is relatively low, and there will be no problem of excessive local current density at the point where the RF head 12 fits the eyelid skin, thereby improving the safety of treatment.

[0058] Specifically, after transmitting radiofrequency current to at least two electrodes 121, any two of the at least two electrodes 121 are switched to positive and negative electrodes. When the number of electrodes 121 is even, every two electrodes 121 form a first electrode group, with the two electrodes 121 in the first electrode group being positive and negative, respectively. When the number of electrodes 121 is odd, every two electrodes 121 form a first electrode group, with the remaining three electrodes 121 forming a second electrode group. The two electrodes 121 in the first electrode group are positive and negative, respectively, while the three electrodes 121 in the second electrode group include one positive electrode and two negative electrodes; alternatively, the three electrodes 121 in the second electrode group include one negative electrode and two positive electrodes. Thus, two or three electrodes 121 in both the first and second electrode groups can form a closed circuit upon contact with the eyelid. It should be noted that the second electrode group can also consist of an odd number of electrodes 121 greater than three, including one positive electrode and multiple negative electrodes, or one negative electrode and multiple positive electrodes. It should be noted that the polarity of each electrode 121 is changeable and can be converted into a positive electrode or a negative electrode.

[0059] Preferably, the number of electrodes 121 is three to facilitate processing and ensure thermal therapy effects.

[0060] Specifically, it also includes a control unit, which is used to transmit radio frequency current to the electrode 121.

[0061] The control unit includes a power supply, a transformer, an RF generator, a power control module, and a relay. The current from the power supply is stepped down by the transformer to a voltage that the human body can tolerate. The RF generator changes the current frequency, and the power control module changes the power. The RF current is then transmitted to electrodes 121. The relay switches each electrode 121 to either positive or negative.

[0062] More specifically, the radio frequency generator adjusts the current frequency to a medium frequency current of 1-4 MHz.

[0063] The power control module consists of multiple resistors connected in series. The current is changed by switching the number of resistors in series, and the power is changed when the voltage remains constant.

[0064] More specifically, an electrode plate is provided at the connection end of the handheld pole 11. Multiple electrode connectors are provided on the electrode plate, each of which is connected to the control unit via a wire 4. When the RF head 12 is connected to the handheld pole 11, the electrodes 121 on the RF head are electrically connected to the corresponding electrode connectors on the electrode plate. The control unit transmits RF current to the electrodes 121 via the electrode connectors.

[0065] Specifically, the main body 2 is provided with buttons for controlling the control unit.

[0066] Preferably, the radio frequency end of the radio frequency head 12 can be attached to the entire eyelid.

[0067] At least two electrodes 121 on the radio frequency head 12 uniformly heat the entire skin tissue of the eyelid at the same time, so as to quickly increase the temperature of the entire skin tissue of the eyelid, enhance the thermal therapy effect, and shorten the treatment time of heated eyelids, thereby avoiding long-term overheating damage to the patient's eyelids, ensuring the safety of treatment, improving the patient's treatment comfort, and avoiding the problem of uneven heating of the eyelids and poor thermal therapy effect caused by excessive local power density when the radio frequency head 12 locally heats the eyelids.

[0068] Furthermore, the end surface of the RF end of the RF head 12 is a plane, an inwardly concave arc surface, or an inwardly concave long arc surface.

[0069] Preferably, the end face of the radio frequency end of the radio frequency head 12 is an inwardly concave arc surface or an inwardly concave long arc surface, so as to fit the outside of the eyelid, increase the effective area, and heat the meibomian gland tissue more evenly, thereby improving the thermal therapy effect.

[0070] More preferably, when the end surface of the RF end of the RF head 12 is an inwardly concave, elongated arc, the RF head 12 includes two RF ends, which are horizontally spaced apart and connected by an insulator connecting rod, and the two RF ends are fixed to the same connecting end. During use, the two connecting ends of the RF head 12 can respectively abut the exterior of the patient's upper and lower eyelids, simultaneously providing thermal therapy to the patient's entire eye, thereby improving treatment efficiency.

[0071] Furthermore, the electrode 121 is in the shape of a ring, a long strip or a circle.

[0072] Specifically, when the electrode 121 is in a circular ring shape, at least two electrodes 121 are concentric rings.

[0073] When the electrodes 121 are in the shape of long strips, at least two electrodes 121 are spaced apart along the length direction of the radio frequency head 12 and extend along the width direction of the radio frequency head 12. Alternatively, at least two electrodes 121 are arranged in a ring shape.

[0074] When the electrodes 121 are circular, at least two electrodes 121 are spaced apart along the length direction of the radio frequency head 12. Alternatively, at least two electrodes 121 are arranged in a ring shape.

[0075] The electrodes 121 arranged as above can be evenly distributed on the radio frequency end of the radio frequency head 12 , so as to ensure uniformity of the radio frequency current applied by the radio frequency head 12 on the eyelid.

[0076] Furthermore, the end surface of the radio frequency end of the radio frequency head 12 has different diameters. Preferably, the diameter of the radio frequency end of the radio frequency head is 20 mm, 15 mm or 13 mm to adapt to the eyelid size of most patients.

[0077] It should be noted that the end face shape of the RF end, the shape of the electrodes 121 , the arrangement of the electrodes 121 and the end face diameter of the RF end can be arbitrarily combined to form different types of RF heads 12 .

[0078] Furthermore, the radio frequency head 12 is detachably connected to the handheld rod 11. When in use, different types of radio frequency heads 12 can be replaced accordingly according to the eyelid sizes of different patients.

[0079] Specifically, the connection end of the radio frequency head 12 is provided with a first thread 124, and the connection end of the handheld rod 11 is provided with a second thread 111 adapted to the first thread 124. The connection end of the radio frequency head 12 is threadedly connected to the connection end of the handheld rod 11 for easy assembly and disassembly.

[0080] Preferably, the connection end of the radio frequency head 12 is inserted into the connection end of the handheld rod 11 and the two are threadedly connected.

[0081] Furthermore, the radiofrequency therapeutic device for meibomian gland dysfunction and dry eyes also includes an eye shield 3, which is an arc-shaped body. The eye shield 3 is an insulating eye shield that can be worn on the eyeball to cover the cornea and sclera to isolate the eyelids and prevent the radiofrequency current applied to the eyelid by the radiofrequency head 12 from damaging the eyeball.

[0082] Specifically, the eye shield 3 is a rubber or ceramic eye shield.

[0083] Furthermore, the main body 2 includes a housing 21 . The control unit is disposed in a cavity of the housing 21 .

[0084] Furthermore, a first receiving slot 212 for receiving the radio frequency head 12 is defined on the housing 21 , and a first cover 213 for opening or closing the first receiving slot 212 is also provided on the housing 21 .

[0085] Preferably, a mounting seat 5 is fixedly provided on the bottom wall of the first receiving groove 212 , and the mounting seat 5 is provided with an internal thread. The connecting end of the RF head 12 can be inserted and threadedly connected to the mounting seat 5 to prevent the RF head 12 from shaking and shifting.

[0086] Optionally, the bottom end of the first cover 213 is rotatably connected to the housing 21 via a latch. A latch 2162 is provided on the side wall of the first cover 213 adjacent to the first receiving slot 212, and a latch hole 2161 is provided on the wall of the first receiving slot 212. When the first cover 213 closes the first receiving slot 212, the latch 2162 on the first cover 213 latches into the latch hole 2161 on the first receiving slot 212.

[0087] Preferably, a toggle block is protruding from the side wall of the first cover 213. By toggling the toggle block, the first cover 213 is driven to open the first receiving slot 212.

[0088] Furthermore, a U-shaped plug-in rack 211 is provided on the housing 21, and the operating handle 1 can be plugged into the plug-in rack 211. When the operating handle 1 is not needed, the operating handle is plugged into the plug-in rack 211 for storage.

[0089] Preferably, the housing 21 further defines a second receiving slot 214 and a second cover 215 for opening or closing the second receiving slot 214. A socket rack 211 is provided on the bottom wall of the second receiving slot 214 to store the operating handle 1 in the second receiving slot 214 when not in use.

[0090] Optionally, the bottom end of the second cover 215 is rotatably connected to the housing 21 via a latch. A latch 2162 is provided on the side wall of the second cover 215 adjacent to the second receiving slot 214, and a latch hole 2161 is provided on the wall of the second receiving slot 214. When the second cover 215 closes the second receiving slot 214, the latch 2162 on the second cover 215 latches into the latch hole 2161 on the second receiving slot 214.

[0091] Preferably, a toggle block is protruding from the side wall of the second cover 215. By toggling the toggle block, the second cover 215 can be driven to open the second receiving slot 214.

[0092] Furthermore, a through hole is provided on the insulator 122 of the radio frequency end of the radio frequency head 12, and a temperature sensor 123 is provided in the through hole. The temperature sensor 123 is used to monitor the temperature of the eyelid treatment area.

[0093] The temperature sensor 123 is communicatively connected to the control unit and transmits eyelid temperature information to the control unit.

[0094] When the control unit detects that the eyelid temperature reaches or exceeds the set maximum temperature threshold, it controls the power control module to reduce the output current power or stop outputting the RF current. When the control unit detects that the eyelid temperature reaches or falls below the set maximum temperature threshold, it controls the power control module to continue outputting the RF current or increase the output current power. This stabilizes the treatment temperature at the eyelid between the minimum and maximum temperature thresholds, achieving a constant-temperature thermotherapy effect while preventing overheating and tissue damage, ensuring the safety and feasibility of the treatment.

[0095] Preferably, the heating temperature range of the radio frequency head 12 is 38-44° C., that is, the minimum temperature threshold is 38° C. and the maximum temperature threshold is 44° C. This temperature can effectively melt the abnormal meibum in the meibomian gland ducts and prevent the eyelids from being damaged by overheating.

[0096] Furthermore, a display screen 22 is provided on the housing 21. The display screen 22 is connected to the control unit via a wire. The display screen 22 is used to receive and display the eyelid temperature information, the current, voltage, power and current frequency information of the electrode 121 transmitted by the control unit.

[0097] Specifically, the display screen 22 is rotatably connected to the housing 21 to facilitate adjustment of the display angle of the display screen 22 .

[0098] Preferably, the rotating shaft 221 at the bottom of the display screen 22 is inserted into the rotating hole 218 on the housing 21 , so that the display screen 22 can rotate around the bottom to adjust the angle of the display screen 22 .

[0099] Furthermore, the main body 2 further includes a base 23 .

[0100] The top of the base 23 is horizontally rotatably connected to the connecting seat 231, and the two ends of the connecting seat 231 are connected to the horizontally extending connecting rod 232. Two connecting rings 217 are set at the bottom of the shell 21, and the two connecting rings 217 are correspondingly sleeved on the connecting rod 232.

[0101] The housing 21 can rotate relative to the base 23 around the connecting rod 232, and the housing 21 can rotate horizontally relative to the base 23 through the connecting seat 231. When the doctor holds the operating handle 1 to treat the patient, the display angle of the display screen 22 can be adjusted by adjusting the housing 21, so that the doctor can always obtain the information displayed on the display screen 22 at any time.

[0102] Specifically, the connecting seat 231 is hinged on the base 23 .
