Neurosurgical ultrasonic focusing assisted three-stage atomization cooling and postoperative wound film forming device

A neurosurgical ultrasonic focusing assisted three-stage atomization cooling and postoperative wound film forming device, comprising:

• a transducer housing, wherein a horn II is arranged in the transducer housing, at least two layers of piezoelectric ceramic sheets II are arranged at a top of the horn II, an electrode sheet connected with an ultrasonic generator is arranged between two adjacent layers of piezoelectric ceramic sheets II, a bottom of the transducer housing is of a hemispherical structure, a plurality of piezoelectric elements connected with the ultrasonic generator are arranged inside the hemispherical structure, a copper mesh common electrode is arranged on a surface of the piezoelectric elements, and a bottom of the horn II protrudes from the hemispherical structure of the transducer;
• and
• a nozzle, arranged at the bottom of the horn II, wherein the nozzle is connected with a medical nanofluid storage cup, compressed gas can be introduced into the nozzle, an electrode is also arranged inside the nozzle, so after pneumatic-ultrasonic-electrostatic atomization medical nanofluid can be flushed into a grinding zone in a form of nanofluid droplet jet for effective cooling and lubrication, at the same time, a postoperative wound can be coated effectively.
