Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a meibomian gland thermal shock intervention treatment device. Background Art

[0002] With the widespread use of electronic products, dry eye has become one of the important and common eye diseases, seriously affecting people's quality of life. According to statistics, the global incidence of dry eye is 5.5%-33.7%, and in my country it is 21-33%. Therefore, paying attention to the diagnosis and treatment of dry eye has become an important research topic in ophthalmology. Among them, 70% of dry eye is caused by meibomian gland dysfunction (MGD), and the proportion of MGD in dry eyes is as high as 87.6%. Therefore, the research and development of medical equipment for MGD is one of the important development directions for the treatment of dry eye.

[0003] Meibomian glands are located in the tarsal plates of the upper and lower eyelids and can be seen through the conjunctiva. The texture of the tarsal plates is relatively hard. There are about 30 meibomian glands in the upper eyelid and about 20 meibomian glands in the lower eyelid. Their direction is perpendicular to the eyelid margin and they open at the eyelid margin. The distal end is a blind end. Meibomian glands secrete a large amount of lipids, which are discharged through the meibomian gland openings at the eyelid margin with blinking and evenly spread on the ocular surface. They are the outermost layer of the three-layer component of the tear film and have the function of reducing tear evaporation and lubricating the ocular surface. The reduction of meibomian gland secretion and discharge of oil will accelerate the evaporation of tears and lead to dry eyes. MGD is divided into insufficient secretion type and discharge disorder type, of which the latter accounts for the vast majority. Long-term meibomian gland lipid discharge disorder, on the one hand, the accumulated old lipids seriously affect the gland's secretory function, and at the same time, it will cause excessive pressure in the meibomian gland cavity, leading to gland atrophy, further aggravating the secretion disorder of the meibomian gland. Therefore, dredging the meibomian glands and dissolving and discharging the old lipids in the meibomian glands are currently important and main methods for treating MGD in clinical practice.

[0004] Currently, the meibomian glands can be unblocked by massaging and squeezing the eyelids, which indirectly applies pressure to the meibomian glands and squeezes out the old lipids in the meibomian gland cavity. However, due to the hard texture of the tarsal plate, a large amount of squeezing force is often required to squeeze out the lipids in the meibomian glands, and the patient feels obvious pain. In addition, the lipids in the meibomian glands need to become liquid before they can be discharged smoothly. MGD causes a large amount of lipids in the meibomian gland cavity to harden and cannot be discharged. Currently, heating is generally used to liquefy the lipids. Studies have shown that when the temperature is 42 degrees, the lipids in the meibomian glands can be dissolved without causing damage to the surrounding tissues. Therefore, the main theoretical basis for treatment is the combined external heating of the meibomian glands to promote the melting of the old lipids in the meibomian gland cavity and then combined with external squeezing to expel them.

[0005] Currently, the devices that use this principle and are on the market or under development include heat or liquid pulsation dry eye treatment devices, warm pulse dry eye treatment devices, etc. This type of device is similar to the manual massage squeezing method in squeezing the meibomian glands. The heating method requires indirectly transferring heat to the meibomian glands by heating the conjunctiva. This process is bound to cause heat loss. At the same time, due to the three-dimensional structure of the meibomian glands and their different depths, the meibomian glands may be heated unevenly, thereby affecting the dissolution and liquefaction of lipids in the meibomian gland cavity.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. After the patient lies flat on the operating table, the eyelid hook is placed in the patient's eye socket through the cooperation between the movable frame, the slider, the support rod and the operating table. Then the support rod is slid on the slider to both sides to drive the eyelid hook to move to both sides, pulling the upper eyelid upward and the lower eyelid downward respectively, so that the patient's eyelids are opened, which is convenient for medical staff to observe the location of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage; at the same time, it is prevented that the patient blinks during the treatment process to affect the treatment effect, and there is no need for medical staff to continuously open the patient's eyelids, thereby improving the treatment efficiency of meibomian gland blockage;

[0021] 2. Power on the heating wire to heat the needle at the end of the injection device to 42 degrees. Then move the injection device so that the needle passes through the opening of the meibomian gland and is inserted into the bottom of the meibomian gland cavity along the direction of the meibomian gland. After heating the meibomian gland with the needle for 30 seconds, the lipid in the meibomian gland is completely melted. Then press the block extending to the outside of the tube body to push the piston to slide on the tube body, squeeze the medicine in the tube body into the meibomian gland, thereby flushing the meibomian gland cavity, accelerating the discharge of lipids in the meibomian gland, and then improving the discharge efficiency of lipids in the gland cavity, and improving the treatment effect of meibomian gland blockage.

[0022] 3. When it is necessary to adjust the lateral position of the eyelid hook on the operating table, the restriction on the sliding of the slider on the movable frame is released through the cooperation between the limit block, the first protrusion, the first wedge block, and the groove. Then, the limit block is restricted from sliding on the slider through the cooperation between the slider, the second screw, and the guide block, so as to facilitate the subsequent adjustment of the position of the slider on the movable frame, improve the efficiency of the eyelid hook position adjustment, and thus improve the treatment efficiency of meibomian gland obstruction;

[0023] By sliding the slider on the movable frame so that the eyelid hook and the eyeball are on the same horizontal line, the slider, the first screw, the second screw, the guide block, the movable frame, the first spring, the limit block, the first protrusion, the groove, the conical surface, the first inclined surface, and the second inclined surface are matched to limit the slider from sliding relative to the movable frame, so as to avoid the external force accidentally driving the slider to slide on the movable frame during the operation, thereby affecting the fixation effect of the eyelid hook on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage; in addition, according to actual needs, the slider can be fixed at different positions to avoid the slider being driven to move slightly on the movable frame during the fixation process, thereby affecting the effect of the eyelid traction mechanism on fixing the patient's eyelid, thereby further improving the treatment effect of meibomian gland blockage;

[0024] 4. When the longitudinal position of the eyelid hook needs to be adjusted on the operating table, the position of the support rod on the slider is adjusted by the cooperation among the slider, the support rod, the ball, the groove and the second spring, thereby improving the efficiency of adjusting the position of the eyelid hook and thus improving the treatment efficiency of meibomian gland obstruction;

[0025] When the eyelid hook is above the eyeball, the slider, the third screw and the ball bearing cooperate to limit the support rod from sliding on the slider, thereby preventing the slider from sliding on the movable frame accidentally due to external force during surgery, thereby affecting the fixation effect of the eyelid hook on the patient's eyelid, thereby improving the treatment effect of meibomian gland obstruction;

[0026] 5. After the two corresponding eyelid hooks are hung on the patient's upper eyelid and lower eyelid respectively, the eyelid hook slides relative to the support rod by sliding the support rod on the slider, and compresses the third spring provided between the support rod and the eyelid hook. The rebound force generated by the compression of the third spring applies a pulling force to the upper eyelid and the lower eyelid, so that the upper eyelid and the lower eyelid are in an open state, which is convenient for medical staff to observe the position of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage; at the same time, it avoids the patient's blinking during the treatment process to affect the treatment effect, and there is no need for medical staff to continuously open the patient's eyelids, thereby improving the treatment efficiency of meibomian gland blockage;

[0027] 6. When it is necessary to adjust the vertical position of the eyelid hook on the operating table, the movable frame, the second wedge block and the fixed block are used to limit the moving direction of the movable frame to ensure that the movable frame moves vertically, thereby avoiding the need to readjust the horizontal and vertical positions of the eyelid hook on the operating table, thereby improving the treatment efficiency of meibomian gland obstruction;

[0028] When the two corresponding eyelid hooks are in contact with the upper eyelid and the lower eyelid respectively, the second wedge block is restricted from moving relative to the fixed block through the cooperation among the fixed block, the fourth screw, the T-shaped block, the T-slot, the clamping block, the third protrusion, the second wedge block and the third inclined plane, thereby achieving the fixation of the movable frame on the operating table, avoiding the external force from accidentally driving the movable frame to slide on the operating table, affecting the fixation effect of the eyelid hooks on the patient's eyelids, and thus improving the treatment effect on meibomian gland obstruction; at the same time, avoiding the fourth screw from driving the clamping block to rotate, affecting the fixation of the movable frame on the operating table, and thus improving the treatment effect on meibomian gland obstruction.

[0059] On the basis of Example 1, Figure 2 and Figure 3 As shown, when it is necessary to adjust the lateral position of the eyelid hook 5 on the operating table 1, the limit block 13 is pulled outward so that the first protrusion and the first wedge block 15 provided at the end thereof slide out of the groove 12, thereby releasing the restriction on the sliding of the slider 3 on the movable frame 2, and then the second screw 22 is tightened on the slider 3 so that it contacts the guide block 19, and the resistance generated limits the sliding of the limit block 13 on the slider 3, which facilitates the subsequent adjustment of the position of the slider 3 on the movable frame 2, improves the efficiency of the position adjustment of the eyelid hook 5, and further improves the treatment efficiency of the meibomian gland obstruction;

[0060] After the eyelid hook 5 and the eyeball are on the same horizontal line by sliding the slider 3 on the movable frame 2, the second screw 22 is then loosened on the slider 3 to release the restriction on the sliding of the guide block 19 on the movable frame 2, and the limit block 13 is driven to move inward under the action of the rebound force generated by the compression of the first spring 18, until the first inclined surface 16 provided on the first protrusion 14 on the limit block 13 contacts the groove 12, and then the second screw 22 is tightened on the slider 3 to restrict the limit block 13 from sliding on the slider 3, and then the first screw 20 is tightened on the guide block 19, and the conical surface 21 provided at the end of the first screw 20 contacts the first wedge block 15, and the component force generated will drive the wedge The block slides on the limit block 13 until the second inclined surface 17 provided on one side of the wedge-shaped block contacts the groove 12, and the resistance generated by the contact between the first inclined surface 16 and the second inclined surface 17 and the groove 12 limits the sliding of the slider 3 relative to the movable frame 2, so as to avoid the external force inadvertently driving the slider 3 to slide on the movable frame 2 during the operation, thereby affecting the fixing effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect on the blockage of the meibomian gland; in addition, according to actual needs, the slider 3 can be fixed at different positions to avoid the slider 3 being driven to move slightly on the movable frame 2 during the fixing process, thereby affecting the effect of the eyelid traction mechanism on fixing the patient's eyelid, thereby further improving the treatment effect on the blockage of the meibomian gland.

[0061] Example 3

[0062] On the basis of Example 1, Figure 4 and Figure 5 As shown, when the longitudinal position of the eyelid hook 5 needs to be adjusted on the operating table 1, the support rod 4 is slid on the slider 3, and the ball 26 is driven to move outward by the force generated by the contact between the ball 26 and the groove 25, and the second spring 27 between the ball 26 and the slider 3 is compressed until the ball 26 moves into the next groove 25, and under the action of the rebound force of the second spring 27, the ball 26 is driven to reset and contact with the next groove 25, so as to facilitate the adjustment of the position of the support rod 4 on the slider 3, improve the efficiency of the position adjustment of the eyelid hook 5, and further improve the treatment efficiency of the meibomian gland blockage;

[0063] When the eyelid hook 5 is above the eyeball, the third screw 28 is tightened on the slider 3 so that its end contacts the ball 26. The resistance generated after the contact limits the movement of the ball 26 outward, and the resistance generated after the ball 26 contacts the groove 25 limits the sliding of the support rod 4 on the slider 3, so as to avoid the external force inadvertently driving the slider 3 to slide on the movable frame 2 during the operation, thereby affecting the fixing effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect of meibomian gland blockage;

[0064] In addition, when the two corresponding eyelid hooks 5 are respectively hung on the patient's upper eyelid and lower eyelid, the eyelid hook 5 slides relative to the support rod 4 by sliding the support rod 4 on the slider 3, and compresses the third spring 29 provided between the support rod 4 and the eyelid hook 5. The rebound force generated by the compression of the third spring 29 applies a pulling force to the upper eyelid and the lower eyelid, so that they are in an open state, which is convenient for medical staff to observe the position of the patient's meibomian glands and improve the treatment effect of meibomian gland blockage; at the same time, it avoids the patient's blinking during the treatment process to affect the treatment effect, and there is no need for medical staff to continuously open the patient's eyelids, thereby improving the treatment efficiency of meibomian gland blockage.

[0065] Example 4

[0066] On the basis of Example 1, Figure 6 As shown, when the vertical position of the eyelid hook 5 needs to be adjusted on the operating table 1, the movable frame 2 is moved up and down, and the second wedge block 31 provided on the movable frame 2 slides on the fixed block 30 to limit the moving direction of the movable frame 2, so as to ensure that the movable frame 2 moves vertically, thereby avoiding the need to readjust the horizontal and vertical positions of the eyelid hook 5 on the operating table 1, thereby improving the treatment efficiency of meibomian gland obstruction;

[0067] After the two corresponding eyelid hooks 5 are in contact with the upper eyelid and the lower eyelid respectively, the fourth screw 36 is tightened on the fixing block 30, and the two sides of the T-shaped block are in contact with the T-slot 35 respectively, and the T-shaped block 37 is rotatably connected with the T-slot 35, so that the fourth screw 36 drives the clamping block 33 to move on the fixing block 30, and contacts the third inclined surface 32 on the second wedge block 31 through the third protrusion 34 provided on one side of the clamping block 33. The friction force generated after the contact limits the movement of the second wedge block 31 relative to the fixing block 30, thereby achieving the fixation of the movable frame 2 on the operating bed 1, avoiding the external force from accidentally driving the movable frame 2 to slide on the operating bed 1, affecting the fixing effect of the eyelid hook 5 on the patient's eyelid, thereby improving the treatment effect on meibomian gland obstruction; at the same time, avoiding the fourth screw 36 from driving the clamping block 33 to rotate, affecting the fixation of the movable frame 2 on the operating bed 1, thereby improving the treatment effect on meibomian gland obstruction.
