Background The percutaneous minimally invasive technology is a surgical operation method characterized by minimally invasive, and can achieve the purposes of cutting focus, repairing damage and recovering functions by using a miniature instrument and image equipment through a small skin incision. The percutaneous minimally invasive technology has the advantages of small wound, less bleeding, low infection rate, light pain, quick recovery and the like, is an important development direction and trend of modern surgical operation, is widely applied to a plurality of fields such as spinal endoscopes, arthroscopes, laparoscopes, thoracoscopes and the like at present, and is welcomed and trusted by vast patients. The percutaneous minimally invasive technique is implemented on the premise that percutaneous puncture operation is performed, namely, holes are drilled on the surface of skin, a surgical channel from the skin to the focus position is established, and then surgical instruments are inserted through the channel to diagnose and treat the focus, so that minimally invasive surgery is completed. At present, percutaneous puncture operation in the process of establishing a surgical channel is an operation with higher technical difficulty, and needs to be performed under a 'invisible' condition, namely, a doctor cannot directly observe the position and the direction of a puncture needle in a body, and can only estimate and adjust according to anatomical knowledge and clinical experience, so that a learning curve becomes steep. Meanwhile, the risk of complications in the puncturing process is increased, and particularly for the parts with dense important tissue structures, the risk of free hand puncturing under the condition of invisible is extremely high, and deep important structures can be damaged. For example, when a puncture operation is performed in front of the neck, there is a possibility that tissue structures such as a large blood vessel of the neck, esophagus, trachea, thyroid gland, etc. may be damaged. Therefore, the technical staff in the field are dedicated to develop a visualized and noninvasive soft tissue separation and fixation device and a use method, so that the device can be completed under the visualized condition, the safety, the accuracy and the efficiency of operation are improved, and a foundation is laid for the safe and accurate establishment of a subsequent operation channel. Disclosure of Invention The invention aims to provide a visual and noninvasive soft tissue separation and fixation device and a use method thereof. The method and the device can complete the separation of the deep important soft tissues under the visual condition, improve the safety, the accuracy and the efficiency of the percutaneous minimally invasive operation, and lay a foundation for the safe and accurate establishment of a subsequent percutaneous minimally invasive operation channel. The technical scheme for solving the technical problems is that the visualized and noninvasive soft tissue separating and fixing device comprises a base block component, a blade component, an ultrasonic probe component and a separating component; The base block assembly comprises a first base block and a second base block, the first base block and the second base block are oppositely arranged, the blade assembly comprises a first blade and a second blade, the side wall of the first base block is connected with the first blade, the second base block is connected with the second blade, a separation assembly is arranged between the first base block and the second base block, and an ultrasonic probe assembly is further arranged between the first base block and the second base block. The ultrasonic probe has the beneficial effects that the first blade and the second blade are integrated with the ultrasonic probe assembly after being folded. The ultrasonic probe assembly probe end is used for carrying out ultrasonic scanning on a target operation part, the ultrasonic probe assembly is slowly pressed down after an important tissue structure boundary is determined, the visual blunt separation is carried out on a deep tissue structure by utilizing the structural characteristics of arc shape and blunt property of the ultrasonic probe assembly probe end until the ultrasonic probe assembly completely separates the important tissue structure and accurately locates a target position, then the handle is rotated to separate the first basic block from the second basic block and the first blade and the second blade connected with the first basic block and the second basic block, the ultrasonic probe assembly is taken out, a safe operation area can be fo
