Abstract

The invention discloses a rotatable scraper spoon used under an endoscope. The rotatable scraper spoon comprises a first handle and a sliding handle slidably arranged on the first handle, wherein a sheath tube is arranged at the front end of the first handle; a mandrel penetrates through the sheath tube and can move back and forth in the sheath tube; one end of the mandrel is connected with the sliding handle; a scraper spoon is fixed at the other end of the mandrel; and the scraper spoon is driven to extend out and retract from the front end of the sheath tube by moving the sliding handle back and forth. The sliding handle is pushed and pulled to drive the mandrel to move back and forth, then the mandrel drives the scraper spoon to move back and forth to get gastric juice by scraping, andafter the gastric juice is scraped by the scraper spoon, the sliding handle is pulled to move backwards to enable the scraper spoon to extend into the sheath tube. The inner wall of the sheath tube can exert a certain sealing effect on the gastric juice in the scraper spoon, so that the gastric juice in the scraper spoon is prevented from leaking out and flowing into a digestive tract, and then the functions of extracting gastric juice on a gastric antrum and a gastric body and collecting the gastric juice and tissues under an endoscope are further realized.

Description

technical field [0001] The present invention relates to endoscopic medical operation instrument, more specifically, it relates to a kind of rotatable spatula used under endoscope. Background technique [0002] my country is one of the countries with a high incidence of peptic ulcer. Helicobacter pylori (Hp) is a factor that causes peptic ulcer. , and has a certain degree of contagion. [0003] Currently, methods for detecting Helicobacter pylori include gastric biopsy mucosal smear, tissue section staining, bacterial culture, C13 / C14 urea breath test, and polymerase chain reaction (PCR) technology. Taking tissue samples from the gastric antrum and gastric body will be accompanied by bleeding, which is a problem for both the patient and the operator. At present, the internationally recognized "gold standard" for the detection of Helicobacter pylori is the C13 / C14 urea breath test. The urea can be decomposed by it, and the CO2 produced is exhaled, and the presence or absence...
