Abstract

The invention discloses an ultrasonic puncture instrument capable of rotationally sampling, which comprises a needle tube assembly and an adjusting assembly used for adjusting the position of a needle tube; the needle tube assembly comprises an outer sheath tube and an inner rotating needle; the inner rotating needle is arranged in the outer sheath tube; the adjusting assembly comprises a position adjusting structure and a power assembly used for driving the needle tube assembly to rotate; the power assembly is arranged in the position adjusting structure and connected with the position adjusting structure; the inner rotating needle is connected with the power structure; the position adjusting structure comprises a front-end adjusting tube and a middle adjusting tube; the outer sheath tube is connected with the front-end adjusting tube; and the inner rotating needle is connected with the middle adjusting tube. The design scheme has the beneficial effects that (1) the outer sheath tube and the inner rotating needle are combined for sampling, so that the injury to other organs during an operation is reduced; (2) the inner rotating needle can rotate, so that a target area can be accurately sampled.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a rotatable ultrasonic puncture instrument for sampling. Background technique [0002] Ultrasound-guided needle biopsy is an interventional ultrasound, which is to puncture living tissue under the guidance of real-time monitoring of ultrasound equipment to obtain cells and tissues. It not only meets the requirements of pathology, but also meets the requirements of immunohistochemistry and electron microscopy. Meet the needs of genetic testing. Because the real-time monitoring of the whole process can clearly display the important organs of the large blood vessels on the puncture path, it can effectively reduce the occurrence of complications, and the operation is convenient, fast, and safe. [0003] At present, the method of ultrasonic puncture is usually a serrated puncture head, which can obtain more tissue and guide the tissue into the puncture tube to...
