| titleOfInvention | A lacrimal duct examination and treatment device |
| abstract | The invention discloses a lacrimal duct inspection and treatment device, which belongs to the technical field of medical devices. It comprises: a punctum dilator with a punctum cannula and a flushing soft lacrimal duct probe, which are separately arranged; through the above method, the punctum dilator with a punctum cannula of the present invention can be expanded as needed to damage the punctum At the same time, the punctal cannula supports the puncta, so that the frictional resistance caused by the punctal contraction force disappears, and the lacrimal duct probing is more accurate to determine the blockage position; the soft lacrimal duct probe can follow the lacrimal duct. Change the probing direction in the direction of the cavity, and turn to the weak direction or the direction of the physiological lacrimal duct, which is not easy to produce iatrogenic false tract; and has a certain rigidity in a short distance, it can probe a certain degree of stenosis and obstruction; it can also be flushed The removal of harmful substances retained in the lacrimal duct can also provide a method for investigating the incidence of anatomical differences (the inability of a rigid lacrimal duct probe to penetrate the lacrimal duct without resistance even in the absence of lacrimal duct obstruction). |
