Problems solved by technology

However, this method is difficult to operate. Medical personnel need to operate the array transducer and the needle tube at the same time, and the components of the vertebral attachment are complex. The ligament is relatively small, and a transducer with a relatively high frequency is required to ensure the resolution of the imaging
When performing a puncture on an obese patient, it is difficult for an imaging array transducer placed outside the body to ensure sufficient imaging depth

Abstract

The invention provides a puncture ultrasonic guiding device and a puncturing ultrasonic guiding device, which relate to the field of medical instruments. The puncturing ultrasonic guiding device includes a puncture needle tube and an ultrasonic transducer. The container is accommodated in the puncture needle tube and extends to the puncture needle, and the ultrasonic transducer includes a plurality of ultrasonic array elements for transmitting and receiving ultrasonic waves, and the plurality of ultrasonic array elements are arranged on the At the puncture needle. In actual use, by using multiple ultrasonic array elements for electronic scanning imaging, the imaging range is wide, and the tissue structure at the front end of the puncture needle can be effectively identified, thereby facilitating the planning of the best puncture path. Compared with the prior art, the puncture ultrasonic guiding device provided by the present invention is closer to the imaged tissue, the imaging is clearer, it is not easy to be blocked by other parts to affect the imaging, and the operation is convenient without the cooperation of multiple medical staff.

Description

technical field [0001] The present invention relates to the field of medical instruments, in particular to a puncture ultrasonic guiding device and puncture ultrasonic guiding equipment. Background technique [0002] Vertebral puncture technology has always been a technical problem in the field of medical applications. Due to the complex tissue environment around the human spine and lumbar spine, various components of fat, muscle, ligament, hard bone, and cartilage have increased the difficulty for medical staff to puncture the vertebrae. Therefore, a real-time and effective method is needed to guide medical personnel to perform puncture. [0003] Compared with X-ray, CT, etc., ultrasound is a real-time, portable, less painful, and no side effect imaging method, so ultrasound-guided vertebral puncture has attracted more and more attention. In the prior art, the ultrasound-guided puncture method is mainly to guide the advance route of the needle tube by fixing or not fixing...
