Description

Rotatable spatula that uses under scope

Technical Field

The invention relates to a medical surgical instrument under an endoscope, in particular to a rotatable spatula used under an endoscope.

Background

As one of the countries with high incidence of peptic ulcer, China, Helicobacter pylori (Hp) is a factor causing peptic ulcer, is a gram-negative Helicobacter parasitizing on the gastric mucosa of human, is related to a plurality of gastrointestinal tract diseases, and has certain infectivity.

The current methods for detecting helicobacter pylori include gastric biopsy mucous membrane smear, tissue section staining, bacteria culture, C13/C14 urea breath test, Polymerase Chain Reaction (PCR) technology and the like, wherein the first three methods are all to take gastric antrum and stomach tissue samples by endoscope, bleeding is accompanied when the gastric antrum and stomach tissue samples are taken, and the method is a trouble for patients and operators. At present, the internationally accepted "gold standard" for helicobacter pylori examination is the C13/C14 urea breath test, which utilizes the characteristic of urease with high activity of helicobacter pylori, so that 13C or 14C labeled urea can be decomposed by a subject after oral administration, generated CO2 is discharged through breath, and the existence of helicobacter pylori infection can be judged by measuring the change of labeled CO2 in exhaled gas. The detection method belongs to indirect detection, and false negative detection results can be caused if a subject takes acid-inhibiting drugs or antibiotics before. In addition, this method is to judge whether positive is found by the cut-off value, that is, HP ≦ 100 is negative and HP ≦ 100 is positive and > 100 is positive, and if the measured value is less than 100, negative is shown on the report sheet, and the meaning of HP value is unknown to the general subjects, and it is known whether positive or negative only, and if negative, it is good for everything. For negative subjects, hospitals do not generally prescribe medicines, and the subjects do not pay attention to the medicines, so that further propagation of HP and even deterioration of various stomach lesions can be artificially caused. This is why the "last examination or negative examination, which often becomes so high in every half year", is one of the drawbacks and risks of the urea breath test for HP. There is also a method for detecting HP, namely Polymerase Chain Reaction (PCR), which is a non-invasive method for diagnosing helicobacter pylori infection by using molecular biology technology, and has the advantages of strong specificity, high sensitivity and the like, and can detect helicobacter pylori globulus, which is difficult to culture, as few as 100 bacteria, and helicobacter pylori in saliva and gastric juice samples; because only trace amount of DNA is needed and no viable bacteria exist, the helicobacter pylori except the stomach, such as dental plaque, feces and the environment can be detected, and recurrent reinfection can be identified through DNA sequence analysis; can also be used for researching the pathogenic gene of helicobacter pylori and further deeply discussing the pathogenesis of the helicobacter pylori. The technology is used for detecting helicobacter pylori in saliva, and if the technology is used for detecting gastric juice and gastric mucosa, instruments for tissue and gastric juice extraction in vivo need to enter a gastroscope. At present, no special instrument for the technology is found at home and abroad, and the popularization of the technology is greatly limited due to no special instrument, so that an instrument which is used under an endoscope and can extract gastric juice and tissues is urgently needed to be designed.
