Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a tear duct flushing needle head with a light source. BACKGROUND

[0002] Tear duct obstruction is a common ophthalmic disease, which is mainly caused by obstruction of lacrimal punctum, lacrimal canaliculus, nasolacrimal duct and lower opening of nasolacrimal duct due to various reasons, so that the tear liquid cannot be smoothly discharged, thereby accumulating in the eye and overflowing, causing the patient to frequently tear, which is commonly known as "lacrimal gland obstruction". However, in fact, the lacrimal gland is mainly responsible for producing tear liquid, and the tear duct is responsible for draining the tear liquid, and the tear duct obstruction is generally flushed by a tear duct flusher.

[0003] Tear duct flushing is flushing the tear duct with physiological saline or drugs from the lacrimal punctum to the lacrimal canaliculus by using a special tear duct flusher. When the tear duct flusher is used clinically, it needs to be performed under sufficient light or bright light. However, in primary hospitals or examination rooms, the light is not good, which can easily cause safety hazards. In addition, the needle head of the present needle is a steel needle like a syringe, which can cause the tear duct wall to be pierced. CONTENT OF THE UTILITY MODEL

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a tear duct flushing needle head with a light source, comprising a needle cylinder and a liquid storage cylinder, the liquid storage cylinder is arranged in the needle cylinder, a piston is arranged in the liquid storage cylinder, the piston is connected with a piston rod, the right end of the liquid storage cylinder is threadedly connected with a needle seat, the needle seat is fixedly connected with a needle tube, the needle tube is arranged in a curved shape, a flushing needle head is fixedly connected to the right side of the needle tube, a handle is arranged on the left side of the needle cylinder, a fixing hole and a light emitting assembly are arranged on the right side of the needle cylinder, and the fixing hole is threadedly connected with a bolt.

[0006] Preferably, the light emitting assembly comprises a light emitting tube, a power supply and a mounting plate, the power supply is fixedly connected with the mounting plate, a switch is arranged on the power supply, a mounting hole is arranged in the middle of the mounting plate, and the bolt can pass through the mounting hole to fix the mounting plate on the right side of the needle cylinder.

[0007] Preferably, the flushing needle head is a soft tube made of a high polymer material.

[0008] Preferably, the light emitting tube is in a circular ring shape.

[0009] The utility model has the following technical effects and advantages:

[0010] The light emitting assembly can well compensate for the insufficient light source and improve the safety of the operation.

[0011] By changing the flushing needle to soft material, the flushing needle will not damage the lacrimal passage wall when passing through the lacrimal punctum. BRIEF DESCRIPTION OF DRAWINGS
