Novel lacrimal passage drainage tube

Abstract

The invention discloses a novel lacrimal passage drainage tube. The novel lacrimal passage drainage tube includes a probe, a feeding tube sleeves the probe, the middle section part of the feeding tubeis of an open structure, the probe is inserted through the open structure part of the feeding tube, one end of the feeding tube is connected with a first implanting tube, one end of the first implanting tube is connected with a second implanting tube, the tail end of the second implanting tube is provided with a connecting short tube, and the connecting short tube is connected with a lacrimal point limit plug. According to the novel lacrimal passage drainage tube, the design of the lacrimal point plug is adopted to solve the problem that a single tube cannot be fixed in a lacrimal passage, and redundant damage and operation steps completed by double-tube operation are avoided; and the two-stage implanting tube design is adopted, one of the tubes is used for healing, the other one of the tubes is used for access, metal wires are no longer needed to be used for access, a nasal cavity is hooked without using tools, a lacrimal passage pipe can be expanded out spontaneously, and the operation difficulty of surgeries is lowered.

Description

technical field [0001] The invention relates to the technical field of ophthalmic accessories, in particular to a novel lacrimal duct drainage tube. Background technique [0002] At present, the lacrimal ducts on the market are double-tube operation, that is, a silicone tube is placed in the upper canaliculus and the lower canaliculus at the same time for treatment, and according to the strength of the patients, 80% of the patients have no upper canaliculus. If there is a problem, no treatment is needed. This will not only cause unnecessary damage to the upper lacrimal canaliculus, but also increase the difficulty and time of the operation, and bring unnecessary pain to the patient. And the reason why this scene occurs is that the fixing problem of the single pipe cannot be solved always. At the same time, the lacrimal ducts currently on the market need to add a metal guide wire to the hollow tube for lacrimal passage. However, due to the physiological structure of the nasa...

Problems solved by technology

[0002] At present, the lacrimal ducts on the market are double-tube operation, that is, a silicone tube is placed in the upper canaliculus and the lower canaliculus at the same time for treatment, and according to the strength of the patients, 80% of the patients have no upper canaliculus. If there is a problem, no treatment is needed. This will not only cause unnecessary damage to the upper lacrimal canaliculus, but also increase the difficulty and time of the operation, and bring unnecessary pain to the patient.

The reason why this kind of scene occurs is that the fixing problem of the single pipe has been unable to solve

At the same time, the lacrimal ducts currently on the market need to add a metal guide wire to the hollow tube for lacrimal passage. However, due to the physiological structure of the nasal cavity, the lacrimal ducts cannot pass directly through the nasal cavity and need to be hooked with tools. The first step is complicated, inconvenient to operate, and easy to cause nasal cavity damage
