Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a dual xenon lamp handle for an intense pulsed light therapy device. Background Art

[0002] Intense pulsed light, also known as photon rejuvenation, is a high-intensity, wide-spectrum, incoherent light with a wavelength between 500nm and 1200nm. It is a composite light. It is not a single-wavelength laser, but contains multiple wavelengths of light. Through instantaneous high-energy release, it produces photothermal and photochemical effects to achieve the treatment and improvement of skin problems.

[0003] Intense pulsed light technology has been widely used in the field of medical cosmetology due to its advantages of non-invasiveness and wide treatment range. The most common of these is the intense pulsed light therapy device, which uses a dual xenon lamp to generate high-energy, wide-spectrum pulsed light that can penetrate the skin surface and effectively treat a variety of skin problems such as pigmentation, vascular lesions and hair removal. The dual xenon lamp handle, as the core component of the intense pulsed light therapy device, directly determines the output efficiency of light energy, the accuracy and safety of treatment, and its performance has a crucial impact on the treatment effect.

[0004] The dual xenon lamp handle for intense pulsed light therapy devices currently on the market is mainly composed of a handle body, a dual xenon lamp and a cold compress head.

Since the ring 32 can rotate, the use angle of the cold compress head 6 can be adjusted according to the shape and pathological conditions of different parts of the skin. There is no need for medical staff to frequently manually adjust the overall angle of the handle body 1, which will not prolong the single treatment time, thereby improving the work efficiency of medical staff and ensuring the continuity of treatment; And while the treatment is being carried out, the micro motor 41 is started, and the micro motor 41 can drive the first rotating rod 42 to rotate, and the driving gear 43 on the first rotating rod 42 will rotate accordingly, and the driven half gear 45 engaged with it will rotate accordingly, thereby driving the knocking rod 46 to swing left and right to knock the inner wall of the cold compress head 6. In conjunction with the cold compress head 6, the local blood circulation of the patient's skin can be promoted, thereby improving the cold compress effect of the structure.

[0027] When the dual xenon lamp 582 fails after long-term use, the worm 593 is rotated, and the worm wheel 591 engaged with it will rotate accordingly, thereby driving the movable rod 51 to rotate, and the disk 52 at the bottom end of the movable rod 51 will also rotate accordingly. At the same time, the fixed shaft 53 at the bottom of the disk 52 will move left and right inside the limit groove 56, thereby driving the movable plate 55 to move back and forth inside the limit frame 54, and the dual xenon lamp 582 can be removed from the inside of the opening slot 2 to facilitate the staff to carry out inspection and maintenance work on it.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
