Embodiment Construction

[0022] As shown in the figure, the injector main body 1, the elastic presser 2, the injection outer tube 3, the injection sleeve 4, the injection fixture 5, the lacrimal canaliculus plug 6, and the tapered tube 7. The main body 1 of the injector is pen-shaped, the front end is a tapered tube 7, the center of the tapered tube 7 is the injection sleeve 4, and the inside of the injection sleeve is a retractable injection clamp 5; the elastic presser 2 controls the retractable injection Expansion of clamp 5. The drawings in the description are only some embodiments of the present invention, and those skilled in the art can also obtain other drawings according to the structures shown in these drawings without creative effort.

[0023] The tip gripper of the bolus injection fixture can be a claw-lobe (two to five-lobe) structure, and the tip gripper of the two-lobe is a tweezers structure, especially three-lobe. The right end of the elastic presser 2 is fixed with the injection fix...

Abstract

The invention discloses a lacrimal ductile embolism introducer which comprises an unfolder body, an elastic presser, a push sleeve and a push clamp. The elastic presser is mounted on the unfolder body, the front end of the elastic presser is fixed to the push clamp, the push clamp is a tweezers-shaped or gripper-shaped clamp holder with minimum two openings at the front end and used for clamping or containing a lacrimal ductile embolism, the push sleeve is arranged at the most front end of the unfolder body, and the diameter of the push sleeve is 0.05 millimeter larger than that of the tweezers-shaped or gripper-shaped clamp holder clamping the lacrimal ductile embolism. The push clamp is pushed out of an orifice of the push sleeve when the elastic presser performs pressing. The elastic presser is structurally a spring with an arc-shaped projection, and the front end of the spring is fixed to the push clamp.

Description

technical field [0001] The invention relates to a lacrimal canaliculus plug inserter, which belongs to micro instruments used in ophthalmology. The advantage is that there is no need to provide an additional fulcrum during operation, and it is easy to achieve one-handed operation to place various canaliculus plugs safely and stably in the canaliculus. Background technique [0002] In 2017, the second meeting of the Dry Eye Disease Working Group of the International Tear Film and Ocular Surface Society (DEWS II) updated the definition of dry eye. The main content of this meeting is to define dry eye as a multifactorial ocular surface disease characterized by an imbalance of tear film homeostasis and accompanied by ocular discomfort symptoms on the basis of DEWSⅠ, combined with new findings on dry eye in recent years , tear film instability, increased tear osmolarity, ocular surface inflammatory response and injury, and neurological abnormalities are the main pathophysiologic...
