Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cleaning device for impacted fecal stones under colonoscopy. Background Art

[0002] The main cause of most diverticulitis is the impaction of fecal stones. Because fecal stones are stuck in the diverticula for a long time and are difficult to expel on their own, they can cause inflammation and abdominal pain. Patients can only find impacted fecal stones when undergoing colonoscopy. The commonly used method to remove fecal stones is to use biopsy forceps to clamp and peel off the fecal stones, and use clean water under the endoscope to rinse them. However, in clinical application, it is often found that the impacted fecal stones are stubborn and deep. The amount of biopsy forceps is small each time, which is time-consuming, and there is a risk of clamping the mucosa next to the diverticula and causing bleeding. When dealing with deeper diverticula, the use of biopsy forceps has the risk of perforation due to poor control of strength and depth. Therefore, the present application proposes a cleaning device for impacted fecal stones under colonoscopy to solve the above problems. Utility Model Content
