Description

Technical Field

[0001] The invention relates to an eye medical device, in particular to a meibomian gland therapeutic device. Background Art

[0002] In the human eye, the tear film covering the cornea is composed of three layered structures. These three layers are, from the inside to the outside: mucus layer, aqueous layer and lipid layer. The mucus layer is close to the surface of the cornea and is mainly composed of mucus rich in sticky proteins, which acts as a basal layer. The second is the aqueous layer, which constitutes the main body of the tear film. Its importance lies in providing the necessary lubrication and protection for the eyeball, thereby preventing the cornea from drying out. The outermost is the lipid layer, which is composed of a series of lipid substances called meibum or sebum. Although this layer is relatively thin, usually not exceeding 250nm, it forms a protective covering layer on the surface of the tear film, effectively slowing down the evaporation rate of the aqueous layer and maintaining the moist state of the eyes. During the blinking action, the lipid layer can also provide lubrication for the eyelids, thereby preventing the occurrence of dry eye syndrome. Dry eye syndrome is a well-known eye disease, which is usually manifested as dry and uncomfortable eyes. By adjusting and improving the lipid layer, the tear evaporation rate can be effectively reduced and eye lubrication can be enhanced, thereby alleviating or completely curing the symptoms of dry eye to a certain extent.

[0003] Meibomian glands play an important role in the structure of the eye. These specialized fat glands are located on the inner side of the upper and lower eyelids and are responsible for secreting lipids that form the outermost layer of the tear film. The surface of the meibomian glands is covered with holes, through which lipid secretions are discharged to the edge of the eyelids. When mammals blink, these lipid secretions are dispersed, forming the lipid layer of the tear film. Inside the meibomian glands, there are multiple cystic alveoli, which are responsible for flowing secretions into the central duct of the gland. It is worth noting that the opening of the meibomian gland is located at the junction of the inner mucosa and the outer skin. However, the opening of the meibomian gland is easily affected by problems such as inflammation, leading to blockage. This blockage prevents the normal discharge of the meibomian gland fluid, which in turn affects the integrity of the lipid layer. If the lipid layer is not sound or the amount of lipids is insufficient, the evaporation of the aqueous layer will be accelerated, which may eventually cause various dry eye symptoms. In addition, the blockage of the meibomian glands may also cause eye diseases such as meibomitis (sty) and meibomian cysts (granulomas).

[0004] Dry eye is a common eye disease with a variety of causes, but the inability of the meibomian glands to adequately produce a lipid layer is the main cause of common dry eye symptoms. This condition is called "meibomian gland dysfunction," or MGD for short. MGD is mainly caused by the blockage of the meibomian glands. The blockage of the meibomian glands further restricts the flow of sebum, which promotes cell growth around the gland openings, which worsens the blockage of the meibomian glands. In addition, the solidification of sebum at the blockage site can also worsen the blockage of the meibomian glands. Various treatments have been developed to treat dry eye. These include drops designed to simulate and replace the natural aqueous tear film, and drugs designed to stimulate tear-producing cells. The goal of these drugs is to replicate the healthy tear film that is naturally produced as closely as possible. However, these are only symptomatic treatments and do not address the root cause of the problem, which is the blockage and dysfunction of the meibomian glands.

[0005] Currently, the main clinical methods for treating meibomian gland dysfunction (MGD) include meibomian gland hot compress and squeeze massage. The purpose of these two methods is to soften and remove blockages in the meibomian gland channels. Traditional meibomian gland massage is usually performed after hot compress, and medical staff use glass rods, cotton swabs or medical tweezers to squeeze the eyelids. However, this treatment process is often accompanied by pain, which may trigger patients' fear and thus create a psychological burden during the treatment of the disease. The operation process is cumbersome and the force control is not precise. These problems limit the effectiveness of traditional treatment methods and patient acceptance.

[0006] Although the prior art has provided a variety of treatment methods for dry eye, these methods mainly treat symptoms rather than directly address the root cause. In fact, the main problem for many dry eye patients is the obstruction or occlusion in the meibomian glands. Therefore, an effective treatment method for the meibomian glands is urgently needed. However, the above-mentioned clinical treatment methods rely heavily on the operator's skills and experience, and the operation process is complicated and cumbersome, which puts a heavy burden on patients. Therefore, it is necessary to develop a treatment plan that is simpler, less burdensome to patients and can directly solve the root problem.

[0007] CN112842684A discloses a meibomian gland therapeutic instrument, comprising a shell, a pressing device and a bottom pad, wherein the pressing device is arranged in the shell, and comprises a roller, a massage head, a connecting rod, an intermediate gear, a spring, a slider frame and a connecting frame, wherein a part of the roller is exposed from the notch of the shell, a small gear rotating synchronously with the roller is arranged on the roller shaft of the roller, the small gear is meshed with the intermediate gear, the massage head is connected to the first end of the connecting rod, the slider frame has a through hole, the cross-sectional area of ​​the through hole gradually decreases in the direction away from the intermediate gear, the connecting rod is inserted into the through hole, the second end of the connecting rod extends out of the rear end of the through hole, an intermediate gear shaft is arranged on the slider frame, the intermediate gear is installed on the intermediate gear shaft, the intermediate gear is meshed with the The second end of the connecting rod is connected, and the connecting frame is provided with an intermediate gear shaft hole and a roller shaft hole, and the intermediate gear shaft and the roller shaft are respectively installed in the intermediate gear shaft hole and the roller shaft hole, and the outer side of the connecting frame and the slider frame cooperates with the housing in a slide rail manner, and the spring is coupled between the housing and the roller. When the roller is pressed down, the roller overcomes the elastic force of the spring to drive the pressing device to move forward so that the massage head approaches the bottom pad. When the roller is released, the spring is restored so that the roller drives the pressing device and the massage head to retreat. When the roller is rolled, the rotation of the roller drives the connecting rod to swing in the through hole through the pinion and the intermediate gear, and thereby drives the massage head to move along the extension direction of the bottom pad. However, although the meibomian gland therapeutic instrument has a certain pressing function, its structure is complex and not compact enough, and it is inconvenient to operate, and it is difficult to achieve accurate massage head control and stable treatment effect. In addition, although the meibomian gland therapeutic device is equipped with a camera and a display for observing the meibomian gland area, it can only provide a single image mode and lacks multi-mode imaging function. It is impossible to switch different imaging modes as needed to observe the morphology and internal structure of the meibomian glands, which limits the accuracy of diagnosis and the targeted treatment. It is also impossible to provide real-time and accurate image feedback during the treatment process of the meibomian gland therapeutic device, which affects the treatment efficiency and effect.

[0020] Furthermore, the limiting frame is provided with a torsion spring hole, and the first end of the torsion spring is fixed in the torsion spring hole of the limiting frame.

[0021] The present invention has the following beneficial effects:

[0022] The meibomian gland therapeutic instrument of the present invention constructs an efficient and precise pressing mechanism by introducing key components such as roller sleeves, rollers, torsion springs, and intermediate gears, which significantly improves the convenience of operation and therapeutic effect of the therapeutic instrument. The nested design of the roller sleeve and the roller, combined with the elastic force control of the torsion spring, realizes the precise approach and retreat of the massage head, ensuring gentle contact and effective operation of the patient's eyelids during treatment. By pressing down the roller sleeve, the roller overcomes the elastic force of the torsion spring to drive the pressing mechanism forward, so that the massage head is precisely close to the eyelid; when the roller sleeve is released, the torsion spring recovers and drives the massage head to retreat smoothly, avoiding excessive pressure or damage to the eyelid. In addition, the design of rolling the roller sleeve after pressing down allows the rotation of the roller to be transmitted to the push rod mechanism through the intermediate gear, thereby driving the massage head to reciprocate along the extension direction of the meibomian gland, achieving a uniform and stable therapeutic effect, and effectively clearing the blockage in the meibomian gland. Overall, this design not only improves the accuracy and comfort of treatment, but also reduces the difficulty of operation and improves the convenience of use through the optimization of the mechanical structure, providing an efficient and reliable solution for the treatment of meibomian gland dysfunction.

[0023] Compared with the existing solutions, the meibomian gland therapeutic device of the present invention also achieves compact spatial layout and efficient mechanical linkage through its unique optimized design of the pressing mechanism. The linkage coordination mechanism of the roller and the intermediate gear not only saves space, but also makes the entire device more compact than previous designs, easy to operate and carry. This optimized design enables the rotational motion of the roller to be efficiently transmitted to the push rod mechanism, and achieves precise swing control through the eccentric part of the intermediate gear, thereby driving the massage head to perform stable reciprocating motion along the extension direction of the meibomian gland. The compact spatial layout ensures that the therapeutic device can achieve complex mechanical functions within a limited volume while maintaining the convenience and stability of operation. In addition, this design also improves the accuracy of the treatment, allowing the massage head to act on the meibomian gland more accurately, effectively clearing the blockage and improving the treatment effect.

[0024] In a preferred embodiment, the meibomian gland therapeutic device of the present invention further expands its functionality and the accuracy of the therapeutic effect by introducing a camera module. The camera module includes a camera, a filter switcher and a multi-light source fill light, wherein the camera is arranged above the massage head, and can clearly capture the image of the meibomian gland, providing an intuitive basis for diagnosis for the doctor. The use of the filter switcher and the multi-light source fill light enables the therapeutic device to perform full-color or infrared photography as needed. In the full-color photography mode, the filter switcher is empty, and the fill light emits white light, which can clearly present the morphology of the meibomian gland; while in the infrared photography mode, it switches to a near-infrared narrow-band filter and emits near-infrared light, which can observe the internal structure of the meibomian gland more deeply, and helps to find potential lesions or blockages. This multi-mode imaging function not only enhances the pertinence of the treatment, but also improves the accuracy of the diagnosis. At the same time, combined with the heater inside the massage head, the therapeutic device heats the eyelid while applying the pressing effect, so that the blockage in the meibomian gland is softened and squeezed out by heat, which significantly improves the therapeutic effect. This multifunctional design that combines treatment and diagnosis not only improves the efficiency and accuracy of treatment, but also provides great convenience for clinical operations, making the treatment of meibomian gland dysfunction more scientific, efficient and humane.

In addition, when the roller sleeve is rolled, the rotation of the roller is transmitted to the push rod mechanism through the intermediate gear, thereby driving the massage head to move along the extension direction of the meibomian gland. The massage head applies a pressing effect to the eyelid during the movement, and at the same time, the eyelid is heated in combination with the internal heater, so that the blockage in the meibomian gland is softened and squeezed out by heat, thereby unblocking the meibomian gland channel and achieving a therapeutic effect. The therapeutic device is further optimized and equipped with a camera module, including a camera, a filter switch and a multi-light source fill light. When full-color photography is required, the filter switch is in an idle state, and the multi-light source fill light emits white light; when infrared photography is required, the filter switch is switched to a near-infrared narrow-band filter, and the multi-light source fill light emits near-infrared light. During the photography process, the camera module can switch between full-color or infrared modes as needed to provide doctors with more comprehensive diagnostic information. This multi-mode imaging function not only enhances the targeted treatment, but also improves the accuracy of diagnosis. In summary, the multifunctional meibomian gland therapeutic device of an embodiment of the present invention achieves efficient and accurate meibomian gland treatment through an optimized mechanical structure and integrated diagnostic functions, which provides great convenience for clinical operations.

[0058] The specific embodiments of the present invention are further described below.

[0059] See also Figures 1A to 7The example provides a multifunctional meibomian gland therapeutic device, including a roller cover 100, a roller 110, a torsion spring 203, an intermediate gear 120, a front push rod 130, a pressure sensor 140, a rear push rod 150, a massage head 160, a limit frame 201 and a connecting frame 202, as well as a camera 170, a filter switch 180 and a multi-light source fill light 190. The through hole 1301 of the front push rod 130 is concentric with the eccentric hole 122 of the intermediate gear 120 and is connected with an axis, the through groove 1303 of the front push rod 130 is fixed at the rear end of the pressure sensor 140, and the groove end of the rear push rod 150 is fixed at the front end of the pressure sensor 140, the limiting frame 201 is provided with an intermediate gear shaft hole and a roller shaft hole, the intermediate gear shaft and the roller shaft 204 are respectively installed in the intermediate gear shaft hole and the roller shaft hole on the limiting frame 201, the limiting frame 201 is provided with a through hole at the rear end, the rear push rod 150 is inserted between the through holes, the second end of the rear push rod 150 extends out of the rear end of the limiting frame 201, the massage head 160 is connected to the second end of the rear push rod 150, the roller 110 has a roller shaft hole 1105 in the center, and the roller shaft hole 1105 is interference fit with the roller shaft 204. The rack part of the roller 110 meshes with the rack part of the intermediate gear 120. The torsion spring 203 is coupled to the roller shaft 204, the first end of the torsion spring 203 is fixed in the torsion spring hole of the limiting frame 201, and the second end of the torsion spring 203 contacts the roller sleeve 100. When the roller cover 100 is pressed down, the roller cover 100 drives the roller 110 to overcome the elastic force of the torsion spring 203 and drive the pressing mechanism including the massage head 160 to move forward as a whole, so that the massage head 160 is close to the patient's eyelid. When the roller cover 100 is released, the torsion spring 203 is restored to enable the roller cover 100 to drive the roller and drive the pressing mechanism and its massage head 160 to retreat. When the roller cover 100 is rolled, the roller cover 100 drives the rotation of the roller 110 through the intermediate gear 120, the front push rod 130, and the pressure sensor 140, and drives the rear push rod 150 to swing in the through holes of the limiting frame 201 and the connecting frame 202, thereby driving the massage head 160 to make a curved motion away from the connecting frame 202 in both the horizontal and vertical directions.

[0060] When full-color photography of the meibomian glands is required, the camera 170 is turned on through the embedded software, the filter switch 180 is empty, and the multi-light source fill light 190 is turned on through the embedded software to emit white light. When infrared photography of the meibomian glands is required, the camera 170 is turned on through the embedded software, the filter switch 180 is switched to a near-infrared narrow-band filter, and the multi-light source fill light 190 is turned on through the embedded software to emit near-infrared light.

[0061] The multifunctional meibomian gland therapeutic device of the embodiment of the present invention can be used to treat meibomian gland dysfunction by pressing. During the treatment process, by pressing down and rolling the roller, when the massage head is close to the eyelid, the pressing mechanism converts the rotation of the roller into a pressing movement of the massage head along the extension direction of the eyelid (at this time, the movement of the massage head is similar to a linear movement along the eyelid), and the blockage in the meibomian gland is squeezed out, thereby unblocking the meibomian gland channel and achieving a therapeutic effect on meibomian gland dysfunction. At the same time, the morphological characteristics of the meibomian gland under white light and near-infrared light can be observed through the camera module.

[0062] like Figure 1A and Figure 1B As shown, the multifunctional meibomian gland therapeutic instrument mechanism includes a roller sleeve 100, a roller 110, a torsion spring 203, an intermediate gear 120, a front push rod 130, a pressure sensor 140, a rear push rod 150, a massage head 160, a limit frame 201 and a connecting frame 202. The multifunctional meibomian gland therapeutic instrument mechanism is a left-right symmetrical mechanism.

[0063] like Figure 2 As shown, the massage head 160 is connected to one end of the rear push rod 150 , and a groove 151 is formed on the other end of the rear push rod 150 .

[0064] Figure 3 The intermediate gear 120 is provided with a central hole 121 and an eccentric hole 122 .

[0065] FIG. 4A to FIG. 4C The assembly structure of the intermediate gear 120, the front push rod 130, the pressure sensor 140, the rear push rod 150, the limit frame 201, and the massage head 160 is shown. The diameter of the through hole 1301 on the front push rod 130 is adapted to the diameter of the eccentric hole 122 on the intermediate gear 120, and the shaft and hole are connected through the shaft. The inner surface of the intermediate gear 120 faces the limit frame 201. The limit frame 201 is provided with a through hole for the rear push rod 150 to pass through. The contact mode between the rear push rod 150 and the limit frame 201 is line contact, and the rear push rod 150 can slide and rotate between the through holes. Figure 4C A heater 300 is provided inside the massage head 160. While applying pressure on the eyelids, the heater heats the patient's eyelids. The blockage in the patient's meibomian glands is softened by the heat and squeezed out by pressure, thereby achieving a better therapeutic effect.

[0066] like FIG. 5A to FIG. 5B As shown, a first positioning boss 1101 and a second positioning boss 1102 for positioning with the limiting frame 201 , and a first limiting boss 1103 and a second limiting boss 1104 for limiting with the limiting frame 201 are symmetrically arranged on both sides of the roller 110 .

[0067] like Figure 7As shown, the filter switch 180 is fixed in front of the camera 170. The multi-light source fill light 190 is fixed around the front of the camera 170 through the FPC.

[0068] When working, the massage head 160 is also a heat source, and a heater 300 and a temperature sensor 301 are embedded in the massage head. The heater is controlled by a controller. The controller sends a heating signal to the heater, and the heater heats the massage head to increase the temperature. The massage head can transfer heat to the patient's eyelids, so that the temperature of the patient's eyelids increases to a maximum of 42 degrees Celsius, and the blockage in the meibomian gland softens at such a temperature. During the treatment process, the massage head can continuously transfer heat to the eyelids, so that the eyelids maintain temperature during the treatment process. During the treatment process, the massage head continuously transfers heat to the eyelids, while pressing the softened blockage in the meibomian glands to discharge it from the eyelids.

[0069] The multifunctional meibomian gland treatment device of the present invention realizes the treatment of meibomian gland dysfunction and full-color and infrared photography functions by manually operating the roller sleeve. The specific operation is as follows:

[0070] When the roller sleeve is pressed, the roller sleeve drives the roller to overcome the elastic force of the torsion spring, so that the entire pressing mechanism moves forward and the massage head approaches the eyelid. At this time, the relative positions of the roller, the intermediate gear, the front push rod, the pressure sensor, the rear push rod and the massage head remain unchanged, and the whole moves closer to the eyelid. When the roller sleeve is rolled, the rotation of the roller is transmitted to the front push rod through the intermediate gear, and the pressure sensor and the rear push rod swing in the through holes of the limit frame and the connecting frame, driving the massage head to move along the extension direction of the meibomian gland, and its motion trajectory is approximately a straight line. After unloading the force acting on the roller, the torsion spring recovers, driving the pressing mechanism and the massage head to retreat, and the patient's eyelid is no longer under pressure.

[0071] During the treatment process, the pressure mechanism of the therapeutic device can heat the eyelids and apply pressure to squeeze out the blockage in the meibomian glands after being softened by heat, unblocking the meibomian gland channels and achieving the therapeutic effect. At the same time, the camera module equipped with the therapeutic device can perform full-color or infrared photography as needed. When taking full-color photos, the filter switch is empty and the multi-light source fill light emits white light; when taking infrared photos, the filter switch is switched to a near-infrared narrow-band filter, and the multi-light source fill light emits near-infrared light, providing doctors with more comprehensive diagnostic information.

[0072] In summary, the multifunctional meibomian gland treatment device of the present invention achieves efficient and accurate meibomian gland treatment through optimized mechanical design and integrated diagnostic functions, which provides great convenience for clinical operations.
