A special sampler for digestive tract tumor biopsy tissue

Abstract

The invention relates to the field of medical technology, in particular to a special sampler for digestive tract tumor biopsy tissue, which includes a catheter, a sampling box, a sampling mechanism and a pair of clamping knives. The sampling box is arranged on the catheter head through two rotating shafts. The cylindrical surface is provided with a sampling port, the head of the sampling box fits the sampling port on the conduit, two rotating shafts pass through the sampling box and are inserted at both ends of the sampling port in the length direction, and a pair of clamping knives are symmetrically arranged on the head of the sampling box The tail of each clamping knife can be rotatably sleeved on the rotating shaft at the corresponding position, and the sampling mechanism is arranged in the sampling box and the conduit. The invention has simple structure and convenient operation. Each structure is located in the catheter or adheres to the outer wall of the catheter, which will not cause damage to the digestive tract. When sampling, the sampled tissue is cut and clamped by a clamp knife so that the sampled tissue is not easy to fall and lose.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a special sampler for digestive tract tumor biopsy tissue. Background technique [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. Great challenge. Clinically, in order to confirm the nature of gastrointestinal tumors, biopsy samples must be taken.

[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.
