Gastrointestinal endoscope polyp removal collector

Abstract

The invention discloses a gastrointestinal endoscope polyp removal collector. The collector comprises a transparent tube, wherein the two ends of the transparent tube are connected with an absorption cover and a negative pressure device respectively, the transparent tube is connected with a collecting device between the absorption cover and the negative pressure device, the collecting device comprises an inner tube, a plurality of collecting tubes are connected to the interior of the inner tube, filter screens matched with the transparent tube are arranged in the collecting tubes, an outer tube is rotationally connected to the outside the inner tube, the outer wall of the inner tube is matched with the inner wall of the outer tube, the bottom of the inner tube is connected with the inner bottom wall of the outer tube through a spring, and a handle extending out of the outer tube is downwards arranged at the bottom of the inner tube. Compared with the prior art, the collector has the advantages that the structure is simple, polyps can be rapidly removed, and the polyps can be filtered and collected respectively.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a polyp collector for gastrointestinal endoscopy. Background technique [0002] When the gastrointestinal endoscope removes polyps, it needs to be taken out by special grasping forceps or sucked on the mirror surface by negative pressure, and withdrawn with the gastrointestinal endoscope; partially removed polyps slide into the intestinal cavity, which is difficult to grasp, and the doctor gives up grasping and asks the patient to pay attention Excreted with the stool, and then sent for biopsy; some small polyps are easily inhaled into the recovery bottle by negative pressure after resection, and cannot be separated for inspection; for multiple polyps, resected under the gastroenteroscope, it is necessary to grab the polyps and exit the endoscope Afterwards, he went into the mirror again, looked for the second one, cut it again, and repeatedly entered and exited.

[0002] When the gastrointestinal endoscope removes polyps, it needs to be taken out by special grasping forceps or sucked on the mirror surface by negative pressure, and withdrawn with the gastrointestinal endoscope; partially removed polyps slide into the intestinal cavity, which is difficult to grasp, and the doctor gives up grasping and asks the patient to pay attention Excreted with the stool, and then sent for biopsy; some small polyps are easily inhaled into the recovery bottle by negative pressure after resection, and cannot be separated for inspection; for multiple polyps, resected under the gastroenteroscope, it is necessary to grab the polyps and exit the endoscope Afterwards, he went into the mirror again, looked for the second one, cut it again, and repeatedly entered and exited. The patient suffered a lot, and the operation was delayed, which caused a lot of inconvenience. In addition, the polyp specimen was easily contaminated by other tissue fluids, which affected the quality of the specimen, which in turn affected clinical diagnosis and effective treatment. The market Most polyp collectors collect all polyps mixed together, it is difficult to collect polyps separately according to the growth site of polyps, which affects the pathological evaluation of patients
