Background

The medicine guiding instrument is an instrument for transdermal drug delivery targeting accurate treatment by ultrasonic waves, and medicine acts on a focus of a patient through a treatment head of the therapeutic instrument to quickly permeate the medicine to the treatment part in vitro. The general principle of the medicine guide instrument is to adopt the organic programmed combination of three steps of electrohole generation, ultrasonic wave and ion introduction, and the functions of mutual coordination and superposition. A specific artificial biological channel is formed between skin, tissue and cell membrane, and then the medicine directly enters into diseased organ and tissue along the artificial biological channel by strong driving action such as radiation pressure, and a medicine high-concentration infiltration area is formed locally and rapidly, so that the medicine is promoted to be transported into cells, and the therapeutic action of the medicine is exerted.

However, in the aspect of the plug-in connector, the conventional medicine guiding instrument often leads to the plug-in spool to be separated from the medicine guiding instrument through the front pulling, however, the connector of the spool is pulled apart due to the frequent repeated front pulling, so that the whole medicine guiding instrument cannot be used, and therefore, a fast-replaced and connected stable connector is required.
