Therefore, in the process of scraping gout crystals for patients, the fallen crystals can be collected in time to avoid the crystals being scattered on the patient's body or on the operating table. The problem that the gout crystal scraper in the prior art cannot effectively collect the scraped crystals in the process of scraping gout crystals, resulting in the random scattering of crystals, is solved.

[0024] During specific implementation, in order to prevent the crystals entering the crystal storage chamber 11 from entering the negative pressure device under the action of negative pressure, affecting the operation of the negative pressure device or even damaging the negative pressure device, the gout crystal scraping device further includes a filter 50.
