Embodiment Construction
[0048] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and in order to facilitate understanding of their structures and functions, some structures are not shown to scale, so that the advantages and features of the present invention can be more easily understood by those skilled in the art Therefore, the protection scope of the present invention is more clearly defined. Here, some description concepts in the embodiment are first defined: the side close to the conical head end 1 or the probe head end 61, that is, the side away from the dilator holding part 5 or the probe holding part 7 is "down" Either "head" or "front"; the side close to the dilator holding part 5 or the probe holding part 7, that is, the side away from the conical head end 1 or the probe head end 61 is "up", Either "tail" or "after". The side close to the geometric centerline is inside, and the side away from the geometric cen...

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).
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a lacrimal duct inspection and treatment device. Background technique [0002] The current inspection and treatment methods for lacrimal duct obstruction include: lacrimal duct irrigation, lacrimal duct probing, etc. The lacrimal duct probing is generally necessary to first expand the lacrimal point. The head end of the current punctal dilator is a cone with a diameter of 3-4mm. When performing punctal dilation, the doctor does not know when the dilation is in place. It can only be judged based on the doctor's experience. Two situations often occur: [0003] 1. If the expansion is not enough, repeated expansion is required, repeated actions and operating friction increase tissue damage. [0004] 2. Excessive expansion, resulting in punctum damage or even punctum cracking, affects the tear drainage function. [0005] The size of the puncta is 0.2-0.3mm, and it can be ex...
