Abstract

The invention provides a lacrimal passage drainage tube pull-out device which comprises a conveying tube, a traction tube and a balloon arranged at one end of the traction tube, wherein the traction tube comprises a connecting section and an elastic injection section, the balloon and the elastic injection section are arranged at the two opposite ends of the connecting section, and the caliber of the elastic injection section is gradually decreased in the direction away from the balloon; during use, the elastic injection section extends into the conveying tube; part of the conveying tube extends into the nasolacrimal duct of a human body and reaches a drainage tube, the traction tube is pushed to extend out of the nasal cavity, the conveying tube is withdrawn from the nasolacrimal duct of the human body, and a gas or liquid is injected into the balloon through the elastic injection section, so that the balloon is expanded to pull the traction tube, and the drainage tube is pulled out under the driving of the balloon. The lacrimal passage drainage tube pulling-out device is simple and convenient to use, and the technical problem that no corresponding lacrimal passage drainage tube taking-out device exists on the market to take out the lacrimal passage drainage tube is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lacrimal duct drainage tube pulling device. Background technique [0002] Human tears come from the lacrimal gland, which is the organ that secretes tears. Usually, after tears are produced, they are discharged through the lacrimal duct. If the nasolacrimal duct is abnormal, such as stenosis or occlusion, and the tears cannot be exported through the lacrimal duct, epiphora will occur, which will affect the patient's health and quality of life in the long run. [0003] Existing lacrimal duct stenosis or obstruction can be treated by implanting a lacrimal duct drainage tube indwelling. However, after the clinical lacrimal drainage tube implantation operation, if the patient has pathological changes or the condition improves, or the implantation position of the drainage tube deviates, the drainage tube may need to be taken out. [0004] However, since the lacrimal duct o...
