Description

tear duct irrigation device

technical field

The utility model belongs to the technical field of medical treatment, in particular to a lacrimal duct flushing device.

Background technique

The lacrimal duct is the channel through which tear fluid is excreted, and is divided into upper and lower punctum, lacrimal canaliculi, common lacrimal duct, and lacrimal sac. If the lacrimal duct is blocked, the tears will overflow the eyes because it cannot flow into the nasal cavity, resulting in epiphora. To treat epiphora, it is necessary to dredge the lacrimal duct. Rinse well and keep the tear ducts open. Now in the process of lacrimal duct irrigation, the lacrimal duct is first expanded through the punctum enlarger, and then the needle of the irrigator is inserted vertically into the lacrimal punctum, about 1.5~2mm deep, and then rotated 90°, so that the needle tip faces the nasal side, that is, the needle The long uranium is parallel to the eyelid margin, and the needle tip is slowly advanced along the lacrimal canaliculus. If there is no resistance, it will continue to advance 5-6mm, and the flushing drug will be injected into the lacrimal duct. In the process of the existing treatment, the punctum expander is used to expand the punctum first, and then the punctum is flushed, which is troublesome to operate. After the punctum is enlarged, due to the intermittent operation and the retractability of the muscle, the lacrimal duct is flushed. It may be necessary to expand the lacrimal point again before flushing; because there is no scale on the irrigator, it is impossible to determine the length of the irrigation needle in the lacrimal duct, which is easy to damage the lacrimal duct of the patient. If the lacrimal duct is too large, it will also damage the patient's lacrimal duct. At the same time, because the space near the lacrimal duct is relatively limited and narrow, it is not easy to observe the surrounding environment of the lacrimal duct, and it is not conducive to observing the length of the irrigation needle. The damage cannot be detected in time.

The mounting ring is connected with a magnifying glass through a connecting column, wherein the connecting column and the mounting ring are rotated and matched, and the connecting column and the magnifying glass are fixedly connected.

By adopting the above technical scheme, the utility model has the following beneficial effects: the utility model utilizes the liquid injection cylinder to extract the flushing liquid, and the flushing liquid enters the liquid injection cylinder body through the flushing needle; , and then push the push handle forward, the push handle pushes the flushing needle forward through the rigid rod, so that the front of the flushing needle is pushed into the tear duct through the socket of the conical head, and the distance the push handle moves forward can be read out by the pointer, That is, the distance between the irrigating needle and the lacrimal duct can be pushed, and then the handle can be pushed to push the irrigating liquid in the injection cylinder into the lacrimal duct through the irrigating needle to flush the lacrimal duct. When the ring moves forward to the position of the limit snap ring, due to the limit of the limit snap ring, the rubber sealing ring is prevented from continuing to move forward, so as to prevent the irrigating needle from moving forward for too long and damaging the lacrimal duct; A rotatable magnifying glass is provided to facilitate observation of the surrounding lacrimal duct and the presence or absence of bleeding injury.

To sum up, the utility model is easy to operate, the distance from the irrigating needle entering the lacrimal duct can be accurately observed, and a limit snap ring is provided to prevent the lacrimal duct from being damaged during the process of entering the lacrimal duct by the irrigating needle, and it is safe to use.
