Ultrasonic puncture guidance device and ultrasonic puncture guidance equipment

Abstract

The invention provides an ultrasonic puncture guidance device and ultrasonic puncture guidance equipment, and relates to the field of medical instruments. The ultrasonic puncture guidance device comprises a puncture needle tube and an ultrasonic transducer; puncture needle head is arranged at one end of the puncture needle tube; the ultrasonic transducer is contained in the puncture needle tube, and extends to the position of the puncture needle head; the ultrasonic transducer comprises a plurality of ultrasound array elements which are used for launching and receiving ultrasound; and the plurality of ultrasound array elements are arranged at the puncture needle head. During practical use, the plurality of ultrasound array elements are used for carrying out electronic scanning imaging, sothat, wide imaging range can be achieved; and thus, tissue structure in front of the puncture needle head can be effectively recognized, thereby facilitating planning of the best puncture path. Compared with the prior art, the ultrasonic puncture guidance device provided by the invention is closer to imaged tissues, so that, clearer imaging can be achieved; and thus, imaging is not liable to be affected by blocking by other parts. Moreover, the ultrasonic puncture guidance device is convenient to operate; and collaboration of multiple medical stuffs is not required.

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...

AI Technical Summary

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
