Real-time ultrasonic percutaneous puncture suction biopsy injection device

Abstract

The invention provides a real-time ultrasonic percutaneous puncture suction biopsy injection device. An improved ultrasonic probe is an ultrasonic-guided percutaneous puncture bone positioning device;a puncture needle is of a needle core structure with a triangular pyramid-shaped head; a puncture sleeve is sleeved on a main body of the puncture needle; a grab handle is arranged at the tail end ofthe puncture sleeve; external threads are arranged on the outer surface of the puncture sleeve; the handle is of a sleeve type structure with internal threads matched with the external threads of thepuncture sleeve; the handle is screwed on the puncture sleeve through threads, the other end of the puncture sleeve is led in through an ultrasonic probe tunnel inlet of the improved ultrasonic probeand led out through an ultrasonic probe tunnel outlet; one end of the handle is clamped at the ultrasonic probe tunnel inlet of the improved ultrasonic probe. The problems that when important nerves,blood vessels or organs are adjacent to the periphery of a focus, adjacent important structures are easily damaged by percutaneous puncture, and serious complications are generated, and meanwhile, the puncture depth and the accurate position are difficult to grasp are solved. The invention belongs to the field of medical operation instruments.

Description

technical field [0001] The invention relates to a real-time ultrasonic percutaneous puncture aspiration biopsy injection device, which belongs to the field of medical operation instruments. Background technique [0002] When lesions occur in different tissues or organs of the human body, due to their unknown nature, in order to accurately find out the cause, lesion biopsy is required to confirm the diagnosis and provide evidence-based medical evidence for further effective treatment. Conventional surgery has the disadvantages of large trauma, excessive bleeding, accelerated lesion spread, and increased risk of radical surgery. The existing common device is a shotgun biopsy needle. This device is an empirical percutaneous blind puncture for biopsy in the lesion. When the lesion is adjacent to important nerves, blood vessels or organs, the percutaneous puncture will easily damage the adjacent important structures and cause serious complications; at the same time, it is difficu...
