Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a visualized lacrimal duct scraper. Background Art

[0002] The tear duct is located at the inner corner of the eye and is composed of the lacrimal puncta, lacrimal canaliculi, common lacrimal duct, lacrimal sac and nasolacrimal duct. Under normal circumstances, the tears produced by the lacrimal gland pass through the ocular surface, through the upper and lower lacrimal puncta and lacrimal canaliculi, and flow into the lacrimal sac through the common lacrimal duct. Under the action of the lacrimal sac pump, the tears are squeezed and discharged from the nasolacrimal duct into the nasal cavity. The lacrimal canaliculus is part of this system. It is a thin tubular channel with a diameter of about 0.3-0.5mm, a vertical part of about 21-2mm, and a horizontal part of about 8mm. The total length of the nasolacrimal duct is about 18mm, and the lower opening is located 16mm behind the front end of the inferior turbinate; the lumen is narrow and curved. In view of the anatomical characteristics of the lacrimal canaliculus itself, when the conjunctiva or surrounding tissues are inflamed, the lacrimal canaliculus may be affected, leading to inflammatory lesions, so that tears cannot be discharged normally. For early, mild, and simple canaliculitis, conservative treatment methods such as canaliculus squeezing, scraping, and intra-canalicular drug injection can be used to promote the discharge of particles, stones, and secretions in the canaliculus through the tear points, solve the problem of canaliculus blockage, and enable drugs to act on the affected areas of the canaliculus, thereby improving the efficacy of the drugs and achieving the purpose of healing.

[0003] Since the nasal endoscopes currently used in clinical practice are large in size and cannot observe the internal structure of the lacrimal canaliculus, ophthalmic chalazion curettes are generally used in clinical practice to scrape the lacrimal canaliculus. During the process, it is impossible to observe the stones and secretions in the lacrimal canaliculus in real time, and improper scraping may cause iatrogenic damage to the lacrimal canaliculus. Incomplete scraping may result in stones remaining in the lacrimal canaliculus wall, and the inflammation of the lacrimal canaliculus cannot be observed, which brings difficulties to the assessment and prognosis of the disease. Utility Model Content

[0004] The purpose of the utility model is to provide a visual lacrimal duct scraper which is easy to operate and highly practical. During the lacrimal duct scraping operation, the stones, secretions or inflammation in the lacrimal duct can be transmitted to the display in real time, thereby facilitating the doctor to make corresponding evaluations and adjustment measures.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A visualized lacrimal duct scraper comprises a handle, a mirror tube, an electronic camera, a scraper head and a circuit board, wherein the electronic camera is led out from the front end of the handle through an optical fiber, the rear end of the mirror tube is fixedly connected to the front end of the handle, and the electronic camera is sealed and installed on the front end of the mirror tube; the scraper head is fixedly connected to the front end of the mirror tube, and the upper plane of the scraper head is lower than the electronic camera; the circuit board is arranged inside the handle, and a data port is provided at the rear end of the handle, and the data port and the electronic camera are both electrically connected to the circuit board; the data port can be connected to a display through a data line.

[0007] As a preferred solution of the present utility model, the front end of the handle is a tapered structure.

[0008] As a preferred solution of the utility model, a transition slope is provided between the mirror tube and the scraper head.

[0009] As a preferred solution of the present utility model, the mirror tube is made of medical transparent silicone.

[0010] As a preferred embodiment of the utility model, a video sensor and an optical lens system for focusing light are provided inside the electronic camera, and a light source generator and a video transmitter are provided inside the handle; the optical lens system is connected to the light source generator through the optical fiber, the video sensor is electrically connected to the video transmitter, and the light source generator and the video transmitter are both electrically connected to the circuit board.

[0011] As a preferred solution of the utility model, the handle is provided with an adjustment switch for controlling the brightness of the light source, and the adjustment switch is electrically connected to the circuit board.

[0012] Compared with the prior art, the visualized lacrimal duct scraper provided by the utility model has the following beneficial effects:

[0013] During the lacrimal duct scraping operation, the doctor holds the handle. Since the upper plane of the scraper head is lower than the electronic camera, when the scraper head enters the lacrimal duct from the lacrimal punctum, the stones, secretions or inflammation in the lacrimal duct can be transmitted to the display in real time, thereby facilitating the doctor to make corresponding evaluations and adjustment measures. It can not only avoid iatrogenic damage to the lacrimal duct caused by improper scraping, but also avoid the blockage of the lacrimal duct caused by stones and secretions remaining due to incomplete scraping. It is easy to operate and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
