Description

Technical Field

[0001] The utility model relates to a nail channel cleaning device after internal fixation removal in spinal infection debridement surgery, belonging to a surgical operation auxiliary device. Background Art

[0002] Most spinal injuries require internal fixation with a screw-rod system for treatment. Once a spinal infection occurs, most of them require debridement surgery. Since bacteria easily adhere to the surface of screws and other built-in objects, it is difficult to control the infection, so the screws and other built-in objects must be removed at the same time. In order to thoroughly debride, it is crucial to thoroughly debride the residual infection foci in the nail channel. Traditionally, a small scraper is used to scrape off the suspected infected tissue, and then hydrogen peroxide, saline, iodine, etc. are poured in for soaking and flushing. It is difficult to thoroughly debride the nail channel, and it is easy for the infection source to remain, leading to recurrence of infection. Utility Model Content
