Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic instruments, in particular to a disposable sterile lacrimal point dilating head. Background Art

[0002] Punctal embolization is one of the main treatments for dry eyes. Its principle is to reduce tear drainage by blocking the lacrimal canaliculi to increase local tears in the eye. Punctal embolization requires the use of a punctum dilator to dilate the punctum first, then insert the lacrimal plug from the punctum into the lacrimal canaliculus, and finally use a lacrimal duct flushing needle to push the lacrimal plug into the middle of the lacrimal canaliculus. Existing clinical dilator tips are reusable and need to be disinfected after use. It is easy to fail to disinfect in time and not be used enough. Utility Model Content

[0003] The utility model aims to solve the problem that the existing clinical expansion heads are all reused and need to be disinfected after use, which is prone to untimely disinfection and insufficient use.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A disposable sterile lacrimal point dilation tip, characterized in that it includes an dilation tip for lacrimal point dilation, the dilation tip is conical, the end of the dilation tip away from the cone tip is fixedly connected to a syringe connector, the dilation head is detachably connected to the syringe barrel of a commonly used medical syringe through the syringe connector, and the outer surface of the syringe connector is provided with an dilation head mark for identifying the model and size of the dilation head.

[0006] A further improvement is that the inner wall of the syringe connector is provided with a connecting hole for detachable connection with the syringe barrel of a commonly used medical syringe.

[0007] A further improvement is that: the expansion head mark is a color mark of a different color.

[0008] A further improvement is that a skirt is provided on the outer peripheral wall of the end of the syringe connector away from the cone tip.

[0009] A further improvement is that the outer surface of the syringe connector is provided with anti-slip grooves.

[0010] A further improvement is that the length of the expansion head is 0.5 cm to 1.0 cm.

[0011] A further improvement is that: the syringes are provided in multiple types.

[0012] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0013] Through the setting of the syringe connector, the expansion head can be easily disassembled and assembled on different syringes. According to the different conditions of the patients, the expansion head of corresponding length can be selected for treatment. After use, the expansion head can be disassembled and directly discarded, becoming a disposable item, which is safer and more hygienic.

[0014] At the same time, the corresponding syringes can be selected according to the usage habits of different medical staff to meet the usage needs of different medical staff;

[0015] There are markings on the outer wall of the syringe connector, which can easily and quickly find the required expansion head and improve efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
