Description

Technical Field

[0001] The utility model relates to the technical field of meibomian gland conducting tools, in particular to a pair of meibomian gland thermal therapy clamping forceps. Background Art

[0002] Meibomian glands are located in the tarsal plate, and their openings open to the ocular surface along the eyelid margin. Normally functioning meibomian glands can stabilize the tear film, reduce evaporation, and prevent dry eyes by secreting meibomian esters that cover the surface of the tear film. Obstructive meibomian gland dysfunction (o-MGD) is the main type of dry eye, which is characterized by increased viscosity and melting point of meibomian esters, blockage of the meibomian gland ducts and openings by abnormal meibomian esters, excessive keratinization of the meibomian gland terminal ducts, and decreased secretion of the meibomian glands, leading to dry eye symptoms. The average melting temperature of normal meibomian esters is 36°C, while the meibomian esters of MGD patients require an average temperature of 38.5°C to become fluid.

[0003] The current treatment for obstructive meibomian gland dysfunction generally involves using meibomian forceps to clamp and squeeze the eyelids to encourage the meibomian glands to expel abnormal meibum. Because abnormal meibum is hard and the meibomian gland opening is small, it is difficult to encourage the meibum at the meibomian gland opening to be expelled by physical squeezing, and it is difficult to control the amount of force applied. Excessive squeezing can easily cause eyelid damage. Utility Model Content

[0044] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0045] See also Figure 1-6 The embodiment of the utility model provides a meibomian gland thermal therapy clamping forceps, including clamping forceps 23. The clamping forceps 23 include a first clamping plate 231 and a second clamping plate 232 that are arranged opposite to each other.

[0046] A heating component is disposed in the cavity of the first clamping plate 231 and the second clamping plate 232, and the heating component is used to heat the first clamping plate 231 and the second clamping plate 232; the first clamping plate 231 can be attached to the inner side of the eyelid, and the second clamping plate 232 can move closer to or away from the first clamping plate 231 to clamp the inner and outer sides of the eyelid or loosen the eyelid.

[0047] When in use, the first clamping plate 231 and the second clamping plate 232 can clamp and massage the inner and outer sides of the eyelid to heat, melt and discharge the meibum in the meibomian gland.

[0048] The first clamping plate 231 and the second clamping plate 232 are heated by the heating component, and the first clamping plate 231 is attached to the inner side of the eyelid, and the second clamping plate 232 moves closer to or away from the first clamping plate 231 to clamp the inner and outer sides of the eyelid or loosen the eyelid, so that the first clamping plate 231 and the second clamping plate 232 can clamp and massage the inner and outer sides of the eyelid to heat, melt and discharge the meibum in the meibomian gland, and promote the melted abnormal meibum to flow out from the meibomian gland opening. The first clamping plate 231 and the second clamping plate 232 only play an auxiliary discharge role, do not require a large clamping force, avoid eyelid damage, and can improve the patient's comfort.

[0049] Furthermore, the meibomian gland thermal therapy clamping forceps also include a hand-held rod 1 connecting the first clamping plate 231 and the second clamping plate 232 .

[0050] When in use, the hand-held rod 1 is held and the clamping forceps 23 are driven to clamp and massage both sides of the eyelids to heat, melt and discharge the meibum in the meibomian glands.

[0051] Specifically, the method for using the meibomian gland thermal therapy clamping forceps includes the following steps:

[0052] S1: Fully expose the meibomian gland opening under the slit lamp and observe the blockage.

[0053] S2: Hold the hand-held rod 1 and drive the clamping forceps 23 to clamp and massage both sides of the eyelids to heat, melt and discharge the meibum in the meibomian glands until meibum flows out of the meibomian gland openings. For severely blocked areas, the heating and massage time can be extended until the meibum melts.

[0054] S3: After the treatment is completed, use levofloxacin eye drops and apply Divac eye ointment to sterilize and disinfect.

[0055] Furthermore, temperature sensors for monitoring the temperature of the clamping forceps 23 are disposed in the cavities of the first clamping plate 231 and the second clamping plate 232. A battery 3 and a controller are also disposed in the inner cavity 12 of the hand-held rod 1.

[0056] The battery 3 is connected to and supplies power to the heating component, and the controller is connected to the battery 3 and the temperature sensor. The controller is used to control the battery 3 to be turned on and off, and receive the temperature information sent by the temperature sensor, so that the controller controls the heating component to heat the clamping forceps 23 to a temperature range of 30-50°C, which is suitable for melting the abnormal meibum in the meibum glands without damaging the eyelids. Preferably, the temperature range of the clamping forceps 23 is 40-45°C.

[0057] Preferably, a display screen for displaying the temperature of the clamping forceps 23 is also provided on the handheld rod 1, and the display screen is connected to the controller and receives the temperature information of the clamping forceps 23 sent by the controller, so that the temperature of the clamping forceps 23 can be intuitively known from the display screen, thereby improving the operation accuracy.

[0058] Preferably, the hand-held rod 1 is also provided with a plurality of buttons including power on, temperature increase and temperature decrease. The buttons are connected to the controller through wires, and by pressing the buttons, signals for power on, temperature increase and temperature decrease are sent to the controller for easy operation.

The push key 13 is fixedly connected to a push rod 14, and the end of the push rod 14 can abut against the second clamping plate 232. When the push key 13 is pushed along the axial direction of the handle bar 1, the push rod 14 can abut against and drive the second clamping plate 232 to fit against the first clamping plate 231.

[0064] When in use, when the push key 13 is pushed in the direction close to the first clamping plate 231 along the axial direction of the hand-held rod 1, the push rod 14 can abut and drive the second clamping plate 232 to move synchronously in the direction close to the first clamping plate 231, so that the first clamping plate 231 and the second clamping plate 232 are clamped on the inner and outer sides of the eyelid. At this time, the slider on the second clamping plate 232 slides along the first slide groove 2331, and the first elastic member 235 is in a stretched or compressed state. When the push key 13 is released, the first elastic member 235 returns and drives the second clamping plate 232 to move in the direction away from the first clamping plate 213, and then the first clamping plate 213 drives the push rod 14 and the push key 13 to return.

[0065] Specifically, a pushing plate 141 is provided at one end of the pushing rod 14 close to the second clamping plate 232 , and the pushing plate 141 abuts against the second clamping plate 232 to increase the contact area, so as to facilitate pushing the second clamping plate 232 to move.

[0066] Specifically, the inner cavity 12 of the hand-held rod 1 is provided with a slide rail 15, and the slide rail 15 is provided with a second slide groove 151 for accommodating and sliding the push rod 14. The push end of the push key 13 protrudes from the outer wall of the hand-held rod 1.

[0067] When in use, the push rod 14 moves along the second sliding groove 151 to improve the movement accuracy of the push rod 14 .

[0068] Preferably, a second elastic member extending along the axial direction of the handle bar 1 is connected between the inner wall of the handle bar 1 and the push key 13, so that after the push key 13 is pushed along the axial direction of the handle bar 1 and the push key 13 is released, the restoring force of the first elastic member 235 and the second elastic member jointly drives the push key 13 to return, thereby improving the reliability of use.

[0069] Preferably, the number of the push key 13 and the push rod 14 is two, and the second slide grooves 151 are arranged on opposite sides of the slide rail 15. The two push rods 14 are slidably connected in the two second slide grooves 151 in a one-to-one correspondence.

[0070] When the medical staff holds the hand-held rod 1, the corresponding push keys 13 can be pushed on both sides of the hand-held rod 1 to drive the first clamping plate 231 and the second clamping plate 232 to clamp and squeeze the eyelids for massaging, so that the medical staff can operate at different angles.

[0071] Specifically, the heating assembly includes heating resistors 4 disposed in the cavities of the first clamping plate 231 and the second clamping plate 232 , respectively. The heating resistors 4 are connected to the battery 3 via a wire 5 .

[0072] More specifically, the connecting rod 233 is a hollow structure, and a wire 5 for connecting the heating resistor 4 and the battery 3 is passed through the connecting rod 233.
