Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology, and in particular to a corneal foreign body removal device. Background Technology

[0002] Corneal foreign bodies are a common eye injury seen in ophthalmology clinics. Compared to intraocular foreign bodies, corneal foreign bodies pose a greater risk, causing significant irritation symptoms such as tearing, redness, and photophobia. If left untreated for an extended period, patients may experience eyelid spasms. Prompt treatment is crucial to prevent further damage to the patient's health and vision. Corneal foreign body removal is a method to remove foreign objects or rust-like irritants and prevent infection. However, the lack of targeted lighting during removal can compromise accuracy.

[0003] A search revealed a Chinese patent document (authorization announcement number CN219700297U) for a corneal foreign body removal hook, comprising a cylindrical rod, one end of which has a coaxial cylindrical cavity, and the other end of which has a coaxial cylindrical hole. The end of the rod away from the cylindrical cavity has a coaxial annular groove, and a mounting shaft is coaxially mounted within the cylindrical hole. The top of the mounting shaft is located within the cylindrical cavity and coaxially connected to a pressing rod. A spring is connected between the bottom of the pressing rod and the bottom surface of the cylindrical cavity. The spring and the mounting shaft are coaxially arranged. The pressing rod extends to the outside of the cylindrical rod. The bottom of the mounting shaft extends through the outside of the cylindrical rod and has a first locking slot at its end. A second locking slot is located on the side of the mounting shaft near the first locking slot. The device also includes a strip block, with a second locking block and a first locking block sequentially fixed to the bottom of the strip block, the second and first locking blocks not contacting each other. This invention allows for the installation and removal of the needle by pressing and adjusting the pressing rod, providing convenience for the user and greatly improving practicality. Because it is a precision operation, the lack of targeted lighting during foreign object removal will affect the accuracy of the removal. Utility Model Content

[0004] The purpose of this invention is to provide a corneal foreign body removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corneal foreign body removal device, comprising:

[0007] The handheld handle is connected to the disassembly and installation parts. The outer periphery of the handheld handle has external threads, and a protective tube is connected to the outer periphery of the handheld handle. Multiple miniature lamp heads for lighting are installed on the side of the handheld handle.

[0008] The storage tube, threaded to the outer periphery of the handheld handle, is used to store other corneal foreign body removal tools. A magnetic plate with magnetic function is attached to one side of the storage tube, and a protective rubber pad is attached to the side of the magnetic plate near the storage tube, with the rubber pad inside the storage tube.

[0009] As a preferred embodiment, the disassembly and installation components include:

[0010] The mounting plate is connected and fixed to the hand handle using multiple mounting bolts.

[0011] The clamping tube is used to clamp and fix the picking needle, and is fixedly connected to the side of the mounting plate.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] During operation, this corneal foreign body removal device uses multiple micro-light strips to provide strong illumination, which, in conjunction with external lighting, ensures the accuracy and precision of the removal. Compared to relying solely on external lighting, it offers higher accuracy.

[0018] This corneal foreign body remover has a protective tube that protects the needle, reducing the possibility of the needle accidentally affecting other areas before use. The storage tube is used to store other corneal foreign body removal tools, serving a storage function. Before use, the threaded connection makes it easy to remove the protective tube and the storage tube.

[0019] This corneal foreign body removal device has a clamping tube that can store the end of the lancet, and multiple fixing bolts to fix the lancet, thus adapting to the fixation and use of different corneal foreign body removal tools;

[0020] This corneal foreign body remover not only provides illumination but also offers multiple adjustments to meet various usage needs. Attached Figure Description
