Description
Technical Field
The invention relates to the field of medical education simulation training, in particular to an ultrasonic interventional puncture simulation training device and a using method thereof.
Background
Interventional Ultrasound (Ultrasound) technology, which is a branch of modern Ultrasound medicine, is a new technology developed on the basis of Ultrasound imaging to further meet the needs of clinical diagnosis and treatment. Holm and Goldberg used a central fenestrated needle probe for biopsy in 1972, respectively, and initiated clinical application of interventional ultrasound. In 1983, the world interventional ultrasound conference held by Copenhagen formally determined that the interventional ultrasound technology becomes a new subject in ultrasound medicine. The device is mainly characterized in that various operations such as puncture biopsy, X-ray radiography, suction, intubation, drug injection treatment and the like are completed under the monitoring or guidance of ultrasound during implementation, certain surgical operations can be avoided, and the effect equivalent to the surgical operations is achieved. The fine needle is punctured under the guidance of the ultrasonic equipment and directly reaches the focus area, and corresponding operations such as bag liquid suction or medicine injection are carried out, so that the clinical symptoms are relieved. Has the advantages of no operation, no perforation, safe and non-traumatic fine needle puncture, no pain, no recurrence, no hospitalization and the like, and conforms to the treatment concept of the modern medicine. Ultrasound intervention has many advantages: (1) the accuracy can be improved due to the puncture under the real-time ultrasonic monitoring; (2) the complication is less and the medicine is relatively safe; (3) because the puncture is carried out under real-time dynamic monitoring, the puncture on small focuses and large movable organs is not influenced, and the in-vivo situation in the puncture process can be synchronously displayed; (4) the operation is simple, convenient and rapid, the cost is low, the repeatability is strong, and the practical value is high; (5) the ultrasonic equipment is convenient to move, and can puncture at the bedside when necessary. In recent years, with the continuous improvement and development of various puncture needles, catheters, guiding devices and ultrasonic instruments, interventional ultrasound is applied more and more widely in clinic.
Although the ultrasonic intervention operation is convenient and rapid, a large amount of simulation training is needed, the puncture training model has high simulation degree and can also perform good puncture simulation training, but an auxiliary training device for ultrasonic intervention is lacked, at least two persons are needed to cooperate during the ultrasonic intervention puncture simulation training, one person operates an ultrasonic probe and the other person performs puncture training, and the training efficiency of the two persons, which also reduces the tacit is examined; meanwhile, an ultrasonic probe of the existing ultrasonic interventional puncture simulation training device cannot flexibly turn and move to acquire an image at a proper position in the using process; meanwhile, the position of the display is fixed, so that a displayed image cannot be conveniently seen during puncture training, and the puncture process is easy to be discontinuous and fails due to the fact that the display is seen.
