Embodiment Construction

[0028] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] Such as Figure 1 to Figure 4 As shown, the present invention provides a nasal cavity lacrimal sac drainage bracket, which includes a conical drainage body 1 with a large upper part and a smaller lower part. The inner part of the drainage body 1 is provided with a tapered drainage chamber 5 whose aperture gradually decreases from top to bottom. The drainage body 1 The upper end is provided with a drainage tray 2 for contacting with the lacrimal gland, the drainage tray 2 covers the drainage cavity 5, and the surface of the drainage tray 2 is provided with a plurality of drainage holes communicating with the drainage cavity 5, and the drainage holes are evenly distributed on the drainage tray 2, Two drainage b...

Abstract

The invention provides a nasal cavity dacryocyst drainage support frame, which comprises a drainage body, wherein a drainage cavity is formed inside the drainage body, a drainage disc used for being in contact with the lachrymal gland is arranged at the upper part of the drainage body, the upper surface of the drainage disc is a plane, a plurality of drainage holes communicated with the drainage cavity are formed in the drainage disc, the lower part of the drainage body is connected with a drainage branch tube, and the drainage branch tube is connected with the drainage cavity. The nasal cavity dacryocyst drainage support frame has the advantages that the drainage disc is in contact with the lachrymal gland of the human body, the contact area is increased, the tears can be conveniently sucked, the liquid can be discharged out through the drainage branch tube after entering the drainage cavity through the drainage holes, the airflow in a drainage passage is smooth, and the drainage effect is good.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a nasal lacrimal sac drainage bracket. Background technique [0002] Lacrimal duct obstruction is a disease that often occurs at the lacrimal point, lacrimal canaliculus, junction of the lacrimal sac and nasolacrimal duct, and the lower opening of the nasolacrimal duct. The main symptom is epiphora. The lower end of the nasolacrimal duct is an anatomically narrow segment. Susceptibility to obstruction due to nasal pathology. The origin of the lacrimal duct (lacrimal punctum, lacrimal canaliculus, and common lacrimal duct) is narrow and superficial, and is adjacent to the conjunctival sac, so it is easily blocked by inflammation and trauma. [0003] At present, the commonly used methods for the treatment of lacrimal duct obstruction are nasal dacryocystor anastomosis, lacrimal duct intubation, lacrimal duct stent surgery, etc.; A silicone stent that replaces a blocked...
