Ultrasonic medicine liquid permeation promoting device for gastrointestinal tract based on piezoelectric drive and working method of ultrasonic medicine liquid permeation promoting device

Abstract

The invention discloses an ultrasonic medicine liquid permeation promoting device for the gastrointestinal tract based on a piezoelectric drive and a working method of the ultrasonic medicine liquid permeation promoting device, relating to the fields of ultrasound and piezoelectric technology. According to the embodiment provided by the invention, an elastic cantilever beam generates pre-compression force acting on a bolt, by utilizing a base body structure and through motion synthesis generated by vibration of two groups of piezoelectric ceramic plates, anticlockwise elliptical orbit movement is generated at the tail end of the elastic cantilever beam; the tail end of the elastic cantilever beam contacts the surface of the bolt, through friction force, the linear motion of the bolt is realized, meanwhile, pushing force is output, and locating can be carried out on the lesion tissue in the gastrointestinal tract; ultrasonic waves generated by a machine body of a sheet chip-mounted energy converter is utilized for promoting the permeation of medicine liquid, and thus the effect of promoting the permeation of the medicine liquid in the gastrointestinal tract is realized. With the adoption of the embodiment provided by the invention, the side effects generated by unnecessary medicines in the traditional treatment methods are greatly reduced, the lesion tissue is rapidly treated, and finally, the purposes of examination convenience, no trauma, no leads, no pain, no cross infection, dosage reduction and high cure rate are achieved.

Description

Technical field [0001] The invention relates to the field of ultrasound and piezoelectric technology, and in particular to a gastrointestinal ultrasonic liquid medicine permeation device based on piezoelectric drive and a working method thereof Background technique [0002] At present, the improvement of people's living standards and changes in dietary structure have led to the increase in the morbidity and mortality of major gastrointestinal diseases (such as malignant tumors and gastrointestinal bleeding) year by year. The related research has become the research and prevention and control of the international society. the key of. However, the high incidence and incurable problems of gastrointestinal diseases are still international problems, especially for advanced gastrointestinal tumors, there is still a lack of accurate and effective clinical treatment methods. The first choice for treatment is still surgical resection, but it is easy to induce Many postoperative complicat...

Problems solved by technology

However, the high incidence and refractory problems of gastrointestinal diseases are still an international problem, especially in the middle and advanced stages of gastrointestinal tumors, there is still a lack of accurate and effective treatment methods in clinical practice. The preferred method of treatment is still surgical resection, but it is easy to induce Many postoperative complications, among which gastrointestinal bleeding is one of the most serious complications, even threatening the patient's life

[0003] The current difficulty is: there is a lack of controllable, high-precision minimally invasive surgery and drug delivery devices at home and abroad to reduce postoperative complications of gastrointestinal diseases
