Change road tumor biopsy tissue Special sampling device.
Background technique
Tumour refers to body under the effect of the various tumorigenesis factors, and local organization hyperplasia is formed by neoformation, because
This neoformation is in occupancy block-like protrusions, also referred to as neoplasm more, and tumour is also classified into malignant tumour and benign tumour, to tumour
Pathological analysis just needs to be sampled inside tumor analysis.
Clinically, in order to make a definite diagnosis the property of tumor in digestive tract, it is necessary to carry out biopsy sampling, traditional way is to allow patient
It swallows air bag, expands alimentary canal, then doctor's hand-held apparatus carries out biopsy sampling, operates so more troublesome, and doctor compares expense
Power, patient are also more painful.In order to solve this problem, those skilled in the art have invented the sampler of profession, such as authorize public
Number sampler for digestive tract tumor biopsy for being CN201631234U is accused, Authorization Notice No. is the tumor in digestive tract of CN203107168U
Biopsy sampler is utilized on soft support arm and scraping blade is arranged, and patient directlys adopt scraping blade progress biopsy and take without swallowing air bag
Sample, although the sampler of above structure is not necessarily to swallow air bag, the scraping blade protruded, when entering and extracting out to digestion trace interpolation,
Oral cavity, alimentary canal can be damaged, use is very dangerous.Simultaneously without providing visible environment, operation is with feel, tissue
Sample time fully relies on the experience of operator.
Summary of the invention
In view of this, the present invention scrapes sector-meeting counterpart in order to solve to protrude in tumor in digestive tract sampler in the prior art
Chamber and alimentary canal damage, and using unsafe problem, provide a kind of tumor in digestive tract sampler.
