The invention belongs to the technical field of puncture sampling, and discloses a human liver puncture sampling device which comprises a puncture assembly, the puncture assembly comprises a needle cylinder and a puncture needle head, and the puncture needle head is installed on the needle cylinder; the supporting assembly comprises a supporting plate, fixing belts symmetrically hinged to the two ends of the supporting plate, a connecting belt, a sliding groove formed in the connecting belt, a sliding block and an adjusting rotary knob, through cooperation of the fixing belts, the supporting plate, the adjusting rotary knob and other structures, the supporting plate can be firmly fixed to the abdomen, and meanwhile through cooperation of the fixing rotary knob, a clamping ring and other structures, the supporting plate can be firmly fixed to the abdomen; the needle cylinder can be firmly fixed in the fixing frame, then the needle cylinder is limited and fixed through the supporting plate, liver tissue can be extracted only by pulling a piston rod on the needle cylinder during use, operation is easy and convenient, time and labor are saved, the two hands are liberated, the working efficiency is improved, a puncture needle head is prevented from shaking and deviating, and safety is improved.
Description
technical field [0001] The invention belongs to the technical field of puncture and sampling, and in particular relates to a device for puncture and sampling of human liver. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract tissue samples for testing, or a gas or contrast agent is injected into the body cavity for contrast examination, and drugs are injected into the body cavity. Catheter is inserted for angiography, etc., and sampling is to select representative samples from the target. During the treatment of liver disease, medical staff need to perform puncture to obtain liver tissue samples to analyze the pathological changes of the tissue and make more accurate Treatment. [0003] However, the existing puncture sampling device has many defects in actual use. For example, after puncturing, the doctor needs to press the puncture point with one hand to prevent the needle from ...
