Description
Technical Field
The invention relates to an ultrasonic surgical device, in particular to an ultrasonic surgical device integrated with spray water mist and disinfection and anti-infection functions.
Background
Many common injuries which are not timely and endangered for life are often generated in places without operation conditions such as home, travel and field operation, especially when sudden disasters such as earthquake occur, open injuries of a large number of people are caused, and operations such as cutting treatment, hemostasis and coagulation need to be carried out on site in an emergency manner. The existing first-aid method has few methods except the operation of rapidly delivering to the operating room of the hospital, and many lives cannot be recovered in the delivery process because of being unable to be cured in time or stopping bleeding.
However, if the operation treatment is forced on site and the problem of bacterial and viral infection is faced, with the development of modern medical technology, the requirement on sterility during operation is more strict, the number of bacteria and microorganisms in the surrounding environment is related to the success or failure of the operation to a certain extent, how to effectively disinfect the operation part, reduce the operation infection caused by pollution, and always be the subject of attention, the current air disinfection power supply widely adopted in the market is usually the main power supply of alternating current, but these are not considering the use requirement under the field operation condition, and cannot be suitable for rapidly curing the first line of batch wounded in the emergency situations such as war time, natural disasters, serious accidents and the like. Conventional surgical anti-infective/disinfectant systems also suffer from the following drawbacks: bulky and inconvenient to move; the whole machine has high power and high power consumption, and is powered by a 220V power supply, so that the machine cannot be used in a severe power supply environment; the whole machine cannot be shockproof, waterproof and dustproof and cannot be normally used in severe medical environments.
The ultrasonic knife is selected during emergency operation under the severe environment, so that a part of problems can be solved to a great extent in the aspects of hemostasis and healing, but in actual operation, the current ultrasonic knife has certain defects, certain smoke or liquid fog drops are required to be generated during the operation of the ultrasonic knife, the visual field is affected, and in addition, disinfection and infection prevention cannot be synchronously and accurately completed.
In addition, the inventor introduces the ultrasonic technology into the field of circumcision operation for the first time on the same application day, but discovers that although the circumcision operation can be finished in a few seconds to a few minutes by adopting the ultrasonic, the circumcision blood vessel can be healed, the bleeding risk can not occur after the operation, but the problems of smoke generation and smell still exist in the research and development process.
In summary, the following problems exist in the prior art:
(1) In a large number of environments without surgical conditions, timely injury treatment cannot be performed;
(2) The sterilization and infection prevention treatment cannot be accomplished synchronously and accurately when the operation or other treatment is performed in a severe environment;
(3) In addition, the prior art in the field of circumcision has the following problems to be solved as yet: after the foreskin tissue is cut at the time of the operation, the incision can not heal in time; the limitation of the circumcision device structure leads to the poor appearance of the circumferential surface, which can cause a lifelong regretta; a certain probability of operation can occur that a section cannot form a complete ring; the knife blade is required to cut or the scissors are required to cut human tissues during the operation, so that the psychological fear and the physiological pain of the patient are realized; the surgical operation requires nails or rings, which brings psychological and physiological pains to patients; when a stitching manner is adopted, blood vessels are easy to puncture due to uncertain stitching positions, and the blood vessels are difficult to heal, so that postoperative bleeding is easy to occur; the process of taking nails after operation needs to last for a few days or even more than ten days, so that the life of a patient is very inconvenient, and once the activity is severe or the external force is influenced, the nails are easy to be separated, and the danger is caused; post-operative stapling, which leads to bleeding or de-stapling when there is a post-physiologic erection at all times; the cutting surface of the traditional operation mode is scabbed or slowly healed, and the like, so that the foreskin loses the original elasticity; traditional surgical methods need to last for several minutes to half a day, and long surgical time leads to various risks; traditional surgical approaches are prone to bleeding, leading to risk of infectious diseases, and so forth. When the circumcision is carried out by adopting the ultrasound to solve the problems, a certain amount of smoke and smell are easy to generate, the visual field and the operation environment are influenced, and meanwhile, the adhesion between tissues and the cutter head can possibly cause operation failure or bleeding.
