Description

[0002] Ultrasonic micro-mediated technology is a technology developed in China since the early 1990s. It is a new technology developed on the basis of interventional therapy and arteriovenous catheter technology. It is not as painful as interventional therapy and is not expensive. If the temperature continues to rise, the atoms that make up the molecules will separate and form independent atoms. For example, a nitrogen molecule will split into two nitrogen atoms. We call this process the dissociation of molecules in the gas. If the temperature is further increased, the electrons in the atoms will be stripped away from the atoms and become positively charged nuclei and negatively charged electrons. This process is called atomic ionization. The occurrence of the ionization process forms plasma. The production of the needle knife tool was triggered by an accidental event, and the formation of needle knife therapy was gradually formed on the basis of a large amount of clinical practice and experimental research.

[0003] The existing needle knife is not easy to operate due to its small hand-held area; and the existing needle head has a simple structure and a relatively single function. During surgery, the blood flowing out of the patient's wound will affect the ultrasonic imaging effect, which is easy to cause visual misleading or visual blind spots for the doctor; therefore, the present application proposes an ultrasonic micro-interventional needle knife to solve the above problems.
