Abstract

The invention provides a device for pushing out a lacrimal drainage pipe. The drainage pipe comprises a conveying pipe, a push-out needle and a nickel-titanium net arranged at one end of the push-outneedle, when the device is used, the nickel-titanium net is stretched to be pushed in from one end of the conveying pipe, the push-out needle is pushed to push out the nickel-titanium net from the other end of the conveying pipe, the nickel-titanium net restores to the original shape, and the push-out needle is continuously pushed to push out the drainage pipe. The device for pushing out the lacrimal drainage pipe is simple and convenient to use, and solves the technical problem that no corresponding lacrimal drainage pipe pushing-out device exists on the market to take out the lacrimal drainage tube.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lacrimal duct drainage tube pushing 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...
