Living body sampling device for digestive system department

Abstract

The invention discloses a living body sampling device for the digestive system department. The device comprises a cannula, an instrument bin and a handle, the side wall of the cannula is of a sandwichstructure, the interlayer structure of the side wall of the cannula is filled with heat-conducting silica gel, the instrument bin is fixedly mounted at one end of the cannula, a liquid storage box isfixedly mounted in the instrument bin, heat insulation blocks are symmetrically arranged in the instrument bin, a heating rod is fixedly installed between the two heat insulation blocks, a heat conduction ring is arranged on the heating rod, a heat conduction wire is connected to the heat conduction ring, a liquid guide pipe is arranged in the cannula, a suction pump is arranged on the liquid guide pipe, a fixed block is fixedly installed in the cannula, a telescopic rod is fixedly installed on the fixed block, and a sampling needle is fixedly connected to one end, away from the fixed block,of the telescopic rod, the handle is fixedly installed at the end, away from the cannula, of the instrument bin, and the handle is provided with a control button used for controlling the device. The device is adjustable in temperature, more comfortable for a patient to use, and capable of effectively removing hydrops in human tissues, facilitates more accurate observation and sampling for medicalpersonnel, and is simple in structure, convenient and practical.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a living body sampling device for gastroenterology. Background technique [0002] Gastroenterology is a third-level clinical discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Endoscopic examination is a commonly used clinical examination method because it can visually observe gastrointestinal lesions. In the process of endoscopic examination, doctors often use a living tissue sampling device to first pass through the endoscope to sample living tissue. The device is connected to the patient's body, and a certain amount of diseased tissue is removed from the patient's body by cutting, clamping or puncturing for pathological examination. [0003] When the existing living body sampling device enters the human body, because the temperature is lower than the body temperature, it will bring gre...

Problems solved by technology

[0003] When the existing living body sampling device enters the human body, because the temperature is lower than the body temperature, it will bring greater stimulation to the stomach or intestinal tract, causing people's discomfort, and at the same time, there may be fluid accumulation in the patient's diseased tissue Too many mixtures will hinder the observation, affect the accurate extraction of diseased tissues, and bring great troubles to medical personnel
