With the increasing development of science and technology and the modern demand for medical technology, scalpel is no longer purely medical cutting role, in order to achieve accurate and rapid cutting, while having the function of hemostasis, ultrasonic scalpel came into being.
What is ultrasonic scalpel?
Ultrasonic scalpel , known as ultrasonic surgical instrument, it uses the cavitation effect of ultrasound and high-frequency mechanical vibration, change the structure and state of biological tissues, mainly used for surgical operations such as cutting of biological tissues and vascular closure, with less bleeding, less damage to the surrounding tissues, post-operative recovery, etc., it is to replace the mechanical scalpel tissue cutting one of the main electrosurgical instruments, there are "Bloodless scalpel".
How does the ultrasonic scalpel work?
The working principle of ultrasonic scalpel is through the system host current conduction to the handle, handle piezoelectric ceramic sheet activation work, ceramic sheet will be converted into mechanical energy, longitudinal mechanical vibration and expansion in the node of the conduction axis, conduction to the cutter head bite to reach the maximum vibration, the cutter head in contact with the tissue proteins, protein hydrogen bond fracture and protein structural reorganization, protein coagulation and closure of the small tubular lumen, the protein by the vibration of the second level of energy energy, the vibration of the protein. Deep coagulation closure of the larger lumen, while the tissue water vaporization, further help tissue layering, thus achieving cutting, coagulation closed tissue and hemostasis.
What are the advantages of ultrasonic scalpel?
Compared with scalpel, electric scalpel, laser scalpel and other instruments, ultrasonic scalpel has obvious application advantages, it has the function of hemostasis, but also can work in a low temperature state, minimize the scope of damage to the human body of the surgical tool.
Scalpels comparison and analysis:
Mechanical scalpel:
Knife cutting of living physical tissue, compared to other tools and equipment without obvious advantages; trauma, bleeding, long operating time.
Electro-scalpel:
High-frequency current in contact with the muscle body when the tissue is heated, to achieve separation and coagulation of muscle tissue, so as to achieve the purpose of cutting and hemostasis, cutting speed, hemostasis is good; separation and cutting next to the important organs and large blood vessels, there is a smoked crust in the operation.
Laser scalpel:
Laser has a single direction, high energy density, the use of its thermal effect, light effect and electromagnetic effect, rapid separation and coagulation of muscle tissue, smooth incision, less bleeding; surgery with smoke and burnt scabs.
Ultrasonic scalpel:
The head of the ultra-high vibration frequency contact tissue, cavitation effect, so as to achieve cutting, coagulation of the tissue, can work in a low-temperature state, to minimize the scope of damage to the body of the surgical tool; higher price.
How to cast an excellent ultrasonic scalpel?
A complete set of ultrasonic scalpel equipment consists of the following parts: frame, host, handle, foot control device, head and other components. Among them, the ultrasonic scalpel handle by the energy converter, energy amplifier and energy conduction part of the composition, located in the center of the energy converter piezoelectric ceramic, carrying the key role of the conversion of electrical energy into mechanical energy, is to control the vibration frequency of the head of the core components.
A good ultrasonic scalpel, not only need to have stable electrical energy host, safe and hygienic head, but also need to be sensitive and easy to control the handle, piezoelectric ceramics quality is to determine the quality of this component is the key.
Product Recommendation: Transducer for ultrasonic scalpel
The transducer developed by AUDIOWELL is a special piezoelectric ceramic specially designed for ultrasonic scalpel. The large amplitude and high reliability of the product provide a good hardware foundation for the ultrasonic scalpel to realize finer control and more flexible operation.
