Puncture biopsy device for liver malignant tumor

Abstract

The invention discloses a puncture biopsy device for liver malignant tumor. The puncture biopsy device comprises a puncture biopsy device body, wherein the puncture biopsy device body comprises a lifting plate, sliding blocks are arranged at the two ends of the lifting plate, supporting plates are arranged on one sides of the two sliding blocks, fixing seats are arranged on one sides of the two supporting plates, electric push rods are arranged at the top ends of the two fixing seats and located at the two ends of the bottom of the lifting plate, and clamping plates are arranged at the bottom ends of the two fixing seats and located at the bottom ends of one sides of the two supporting plates. According to the puncture biopsy device for liver malignant tumor, a knife cylinder is movably fixed on one side of a moving sleeve, and the moving sleeve is movably arranged outside the lifting plate in a sleeving mode, so that the knife cylinder can rotate by 360 degrees and move in a reciprocating mode, the electric push rods push the lifting plate to ascend and descend, a micro telescopic rod pushes a micro speed reducing motor to drive a spiral blade to rotate and work to extend out of the interior of the knife cylinder, and therefore the collection effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of a puncture biopsy device, in particular to a puncture biopsy device for liver malignant tumors. Background technique [0002] Needle biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. Biopsy may be abandoned, the patient's clavicular vessels are denser and closer to the carotid artery. Bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous improvement of examination methods and methods, the correct rate of diagnosis has gradually increased, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. A correct diagnosis requires a combination of clinic...

Problems solved by technology

[0003] At present, the needle biopsy device is used to collect the soft tissue on the tumor to diagnose the patient's condition. When the traditional primary liver cancer needle biopsy device is used, the doctor needs to hold it to collect the soft tissue of the patient's tumor. This kind of needle biopsy device There is no support for the hand when using it, which leads to poor collection effect. In addition, the collection cannot see the internal situation clearly, causing it to touch other parts, which will cause unnecessary trouble
