Description

Technical Field

[0001] The utility model relates to the technical field of radiofrequency treatment instruments, in particular to a treatment head with an internal temperature control function and a radiofrequency therapeutic apparatus. Background Art

[0002] The main treatment principle of a radiofrequency therapeutic apparatus is that radiofrequency waves are generated at a specific depth under the skin through radiofrequency, acting on the water molecules in collagen. The bipolar water molecules vibrate and rotate at high speed, generating heat by friction, so as to achieve the effect of heating the dermal collagen. During the treatment process, the heating of the dermal collagen fibers first causes the collagen fibers to contract, tightening the loose skin and wrinkles. Subsequently, the thermal effect generated in the dermal layer causes collagen hyperplasia. The newly generated collagen is rearranged and increased in quantity, repairing the aged and damaged collagen layer, thereby achieving the effect of removing wrinkles and tightening the skin. Of course, it can also be used for the rehabilitation treatment of scapulohumeral periarthritis and lumbar muscle strain.

[0003] During the treatment process, the treatment head generates heat. An overheated treatment head is likely to cause burns to patients. Therefore, it is necessary to add a temperature control function to the treatment head. Content of the Utility Model
