Problems solved by technology

[0002] Gastrointestinal disease is a common disease that affects the health of modern people, but because digestion is inside the human body, the diagnosis and treatment of related diseases requires corresponding observation and inspection, so visual detection plays a very important role in the prevention, diagnosis and treatment of gastrointestinal diseases , and the shape of the human digestive tract is a slender pipe, which is distributed between various organs of the human body, and the structure of the digestive tract is irregular. The total length of the digestive tract in the human body is 8m. big challenge
Clinically, in order to confirm the nature of gastrointestinal tumors, biopsy samples must be taken. The traditional method is to let the patient swallow the airbag to expand the digestive tract, and then the doctor takes a biopsy sample with a hand-held instrument. This operation is more troublesome, and the doctor is more laborious. It is more painful. The existing biopsy samplers for digestive tract tumors all use a scraper on the soft support arm. The patient does not need to swallow the airbag, and directly uses the scraper for biopsy sampling. Although the sampler with the above structure does not need to swallow the airbag, it is convex. When the scraper is inserted into the digestive tract and pulled out, it will cause damage to the oral cavity and digestive tract, and it is very unsafe to use. At the same time, the tissue sample taken out is on the scraper, and the tissue sample will easily fall when it is pulled out and cannot be taken out.

Abstract

The invention relates to the technical field of medical treatment, in particular to a sampler special for biopsy of the digestive tract tumor. The sampler comprises a catheter, a sampling box, a sampling mechanism and a pair of clamping cutters. The sampling box is arranged on the head of the catheter through two rotation shafts, a sampling port is formed in the cylinder face of the head of the catheter, and the head of the sampling box fits the sampling port of the catheter; the two rotation shafts penetrate through the sampling box and are inserted in the two ends of the sampling port in thelength direction, a pair of clamping cutters are symmetrically arranged on the head of the sampling box, the tail of each clamping cutter can rotatably sleeve the rotation shaft at the correspondingposition, and the sampling mechanism is arranged in the sampling box and the catheter. The sampler is simple in structure and convenient to operate, all the structures are located in the catheter or fit the outer wall of the catheter, the digestive tract cannot be injured, and during sampling, the clamping cutters clamp and cut the sampling tissue, so that the sampling tissue does not easily falldown and is not easily lost.
