Dry eye is an inflammatory ocular surface disease, and patients can suffer from ocular discomfort such as dry eyes, foreign body sensation, pain sensation, burning sensation and the like, and seriously affect the work and life quality of the patients. About 1.8 hundred million people in China suffer from dry eye, and 4 hundred million people have dry eye symptoms, so that huge economic and social burden is caused. At present, the treatment method of dry eye mainly comprises drug treatment and physical treatment, wherein the physical treatment is the basis of treating dry eye, and the gland secretion function is improved by improving or eliminating the obstruction of a meibomian gland duct through means such as hot compress, meibomian gland massage, meibomian gland sounding and the like, so that the meibomian fat discharge is recovered, thereby treating meibomian gland dysfunction (meibomian gland dysfunction, MGD) and improving the condition of dry eye.
Meibomian glands are fat-secreting glands present in the upper and lower eyelids, which secrete meibum that can cover the topmost layer of the ocular tear film, slowing down tear film rupture, tear evaporation. Obstruction meibomian gland dysfunction (obstructive meibomian gland dysfunction, O-MGD) refers to the blockage of the opening and ducts of the meibomian glands by abnormal meibum, inability to properly drain, reduced meibomian gland secretory function, resulting in lack of meibum coverage of the ocular tear film, and the onset of overevaporative dry eye. It is characterized by abnormal meibum character and high melting point.
Physical therapy for O-MGD disorders may be performed clinically using meibomian gland probing. The meibomian gland opening is dilated by using a meibomian gland probe, a meibomian gland duct is probed, the secretion function of the gland is restored, and dry eye is treated. However, most of the clinical meibomian gland probes are formed by manually bending and grinding the blunt needle tip by using the existing syringe needle, and lack special tools for meibomian gland probing. And the existing meibomian gland probe in clinic has no heating function, can not carry out thermal therapy on O-MGD, and can not carry out suction on abnormal meibum at the same time of probing so as to promote the discharge of the meibum.

Because the outer sleeve 722 and the inner sleeve 721 are connected at one end far away from the shell 1 through the connecting rod 723, the rotating sleeve 72 is hollow, and the space enclosed by the outer sleeve 722 and the inner sleeve 721 forms an eyelid fat channel communicated with the suction head 51.
Further, the specific using method of the meibomian gland probe is as follows:
s1: the topical anesthetic was instilled at a concentration of 0.5% procaine hydrochloride into the lower conjunctival fornix of the eye for topical ocular anesthesia.
S2: the meibomian gland opening is fully exposed under the slit lamp.
S3: after the preheating of the needle 3 is completed, the switch 45 is turned on, the hand-held portion 6 is held and the needle 3 is inserted perpendicularly to the opening of the meibomian gland duct to expand the opening of the meibomian gland duct. When resistance is encountered during insertion, the needle 3 is inserted deeper depending on the physiological length of the meibomian gland duct being probed.
S4: after the needle 3 is inserted into place in the meibomian gland duct, the needle 3 is maintained in the meibomian gland duct for about 30 seconds so that abnormal meibum is melted by heating and discharged.
S5: after the heating probe is completed, the rotating sleeve 72 is rotated to move the needle 3 relative to the rod 2 in the axial direction of the rod 2 to retract the first chamber 11.
S6: the meibum sucking switch is turned on, and the suction head 51 sucks the melted meibum.
S7: after the eyelid fat absorption is finished, the levofloxacin eye drops are dripped into eyes, and then classical special eye ointment is smeared, so that the anti-inflammatory and anti-infection effects are realized.
