Abstract

The invention relates to a water-cooled microwave burning cut heat clotting cutter, which comprises: a cutter tip radiation head, a medium tube, a semi-rigid coaxial cable and an outer tube having a cutting edge at the front end. The cutter tip radiation head and the outer tube have a special structural design, and a unidirectional circulating water cooling system structure is arranged in a cutterbar and a handle, and a micro switch for controlling the start / stop of the microwave output and two-color luminous tube display are mounted on the handle. The clotting cutter has the unique structureand performance in the clinical surgical operation, so that the clotting cutter has the effect of high-efficiency microwave burning and rapid thermal coagulation and hemostasis, because of the lightweight, stable performance and safe use of the water cooling system, and the control switch and the two-color luminous tube display on the handle further increase the spirituality of the present invention in surgical operation. The clotting cutter certainly play an even better role in clinical surgical open surgery with the advantages.

Description

technical field [0001] The invention relates to a water-cooled microwave cauterization and thermal coagulation knife, which is suitable for dissecting and cutting organs and tissues in open surgery, and belongs to the application field of medical microwave technology. Background technique [0002] The "microwave fever" in the 20th century made microwave hyperthermia popular in almost every hospital in China. With the rapid development of modern science and technology, microwave technology first formed a branch of application in the clinical field of microwave physical (thermal) therapy and microwave superficial tissue. [0003] In clinical open surgery, microwave knife is often used as a surgical instrument for dissecting or cutting organs and tissues. The reason why it has a good application prospect is that: macroscopically, the microwave knife is cutting tissue, and microscopically, it is performing thermal coagulation and hemostasis at a very high speed at the same time...
