Description

Technical Field

[0001] This utility model relates to the field of corneal scraping technology, and in particular to a disposable needle for corneal scraping. Background Technology

[0002] Corneal lesion sampling is a commonly used technique in ophthalmological clinical diagnosis. When the cornea is infected, inflamed, or has other lesions, samples are scraped from the lesion site for laboratory examination, such as smear staining, bacterial culture, and fungal culture. This helps to clarify the cause and provides a basis for precise treatment. This technique requires precise and gentle operation to obtain sufficient and representative samples while minimizing damage to corneal tissue. In clinical practice, accurate corneal lesion sampling is crucial for timely diagnosis and effective treatment of corneal diseases. It can help doctors develop personalized treatment plans and improve the cure rate and visual recovery of patients.

[0003] Currently, the corneal scraping needles used in clinical practice pose certain risks. Because corneal tissue is relatively fragile, the tip of the needle can easily puncture the cornea during the scraping process. Once the cornea is punctured, it will not only cause additional pain to the patient, but may also lead to a series of serious complications, such as corneal perforation and intraocular infection, which will seriously threaten the patient's vision, increase the risk of infection spread, and make it difficult to scrape and sample from corneal lesions. Utility Model Content

[0004] To overcome the problem that existing corneal scraping needles pose a high risk of use and the needle tip can easily puncture the cornea during scraping, making it difficult to scrape and sample corneal lesions, this utility model provides a disposable needle for corneal scraping.

[0005] The technical solution is as follows: a disposable needle for corneal scraping includes a scraping needle assembly and a scraping handle assembly; the scraping needle assembly has a scraping handle assembly at its rear end; the scraping needle assembly includes an anti-slip connecting tube, a connector, a connecting rod, a scraping blade, and an interface; the scraping handle assembly includes a handle, a plug, and a grip.

[0006] Furthermore, the front end of the anti-slip connecting tube is provided with a connector, and the connector is fixedly connected to the anti-slip connecting tube; the front end of the connector is provided with a connecting rod.

[0007] Furthermore, the connecting rod is fixedly connected to the connector; the rear end face of the anti-slip connecting tube is provided with an interface, and the interface is integrally formed with the anti-slip connecting tube.

[0008] Furthermore, a scraper is provided at the front end of the connecting rod, and the scraper is integrally formed with the connecting rod.

[0009] Furthermore, a handle is provided at the rear of the anti-slip connecting tube; a plug is provided at the front of the handle.

[0010] Furthermore, the plug and grip are integrally molded, and the plug insertion interface has an internal Luer sliding snap connection.

[0011] Furthermore, a grip handle is provided at the rear end of the grip, and the grip handle is integrally formed with the grip.

[0012] The beneficial effects are: This utility model connects the scraper needle assembly and the sampling handle assembly through an anti-slip connecting tube, and the connection method of inserting the plug into the interface with interference fit improves the ease of installation and disassembly of the scraper needle assembly, thereby reducing the cost of consumables and increasing the service life of the sampling handle assembly. At the same time, compared with the traditional corneal lesion scraping sampling method, the scraper structure is smoother and safer to use. The arc structure on one side is used for scraping and accumulating the sample, improving the convenience of sampling. In contrast, the tip of the traditional needle is sharp and can easily puncture the cornea if used improperly, causing irreparable damage.

[0013] By designing the sampling grip assembly, the handle of the sampling grip assembly is used as the point of force exertion when the hand is holding it, making the sample scraping action of the scraper more stable and efficient, improving anti-slip performance, and reducing sampling difficulty.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-5 As shown, the disposable needle for corneal scraping includes a scraping needle assembly 1 and a scraping handle assembly 2; the scraping needle assembly 1 has a scraping handle assembly 2 at its rear end; the scraping needle assembly 1 includes an anti-slip connecting tube 101, a connector 102, a connecting rod 103, a scraping blade 104, and an interface 105; the scraping handle assembly 2 includes a handle 201, a plug 202, and a grip 203.

[0023] The anti-slip connecting pipe 101 has a connector 102 at its front end, and the connector 102 is fixedly connected to the anti-slip connecting pipe 101; the connector 102 has a connecting rod 103 at its front end.

[0024] The connecting rod 103 is fixedly connected to the connector 102; the rear end face of the anti-slip connecting tube 101 is provided with an interface 105, and the interface 105 is integrally formed with the anti-slip connecting tube 101.

[0025] The front end of the connecting rod 103 is provided with a scraper 104, and the scraper 104 is integrally formed with the connecting rod 103.

[0026] A handle 201 is provided at the rear of the anti-slip connecting tube 101; a plug 202 is provided at the front of the handle 201.

[0027] The plug 202 and the grip 201 are integrally formed, and the plug 202 is inserted into the internal Luer sliding connection of the interface 105.

[0028] The scraper needle assembly 1 and the sampling handle assembly 2 are connected by the anti-slip connecting tube 101. The plug 202 is inserted into the interface 105 for a fixed connection, which improves the ease of installation and disassembly of the scraper needle assembly 1, thereby reducing the cost of consumables and increasing the service life of the sampling handle assembly 2. At the same time, the scraper 104 is designed to be smoother and safer to use than the traditional corneal lesion scraping sampling method. The arc-shaped structure on one side is used to scrape and accumulate the sample, which improves the convenience of sampling. In contrast, the tip of the traditional needle is sharp and can easily puncture the cornea if used improperly, causing irreparable damage.
