Example 1
Referring to fig. 1, the present embodiment provides a photomedical device, including:
the central shaft 10 is provided with a central shaft,
a sliding sleeve 20 which is slidably sleeved outside the central shaft 10;
the supporting structure I and the supporting structure II are fixed on the outer surface of the sliding sleeve 20;
the support structure I and the support structure II jointly form an adjusting profile which wraps the central shaft 10;
a flexible light source 50 connected to both the support structure I and the support structure II; the flexible light source is distributed along the adjusting contour and used for providing a therapeutic light source;
the support structure I and the support structure II are unfolded when the sliding sleeve is stressed so as to unfold the flexible light source; the support structure I and the support structure II are contracted such that the adjustment profile becomes wavy.
In the present embodiment, the central shaft 10 is made of steel wire, thin deformable plastic rod or tube, hollow or solid rubber tube; the end part of the support structure I and the support structure II is used for extending into the body for treatment, the other end is exposed out of the body, and the end part exposed out of the body is provided with a control structure 60.
In this embodiment, the supporting structure I is composed of a plurality of supporting strips I31; the supporting structure II consists of a plurality of supporting strips II 41;
one end of the supporting strip I31 is fixed at the end of the central shaft 10, and the other end is fixed at the upper part of the sliding sleeve 20;
one end of the supporting strip II41 is fixed at the end of the central shaft 10, and the other end is fixed at the lower part of the sliding sleeve 20;
support strip I31 and support strip II41 are circumferentially spaced apart.
Support bars I31 and II41 may also be made of steel wire, thin deformable plastic rod or tube, hollow or solid rubber tube. Wherein, only the middle part of the length direction of the supporting strip I31 is connected with the flexible light source; because support bar I31 is shorter than support bar II41, and its spherical contour lies within the spherical contour formed by support bar II41, when the flexible light source is simultaneously placed on support bar I31 and support bar II41 and the support structure I and support structure II are unfolded, the ends of support structure II form a spherical or ellipsoidal contour, with which the flexible light source is unfolded; when the support structures I and II are contracted, as shown in fig. 1d, the wavy adjustment contour is formed, and the flexible light source 50 follows the wavy surface, so that the flexible light source between two adjacent support strips II41 is prevented from being damaged due to the excessive folding angle when being contracted, and the flexible light source is protected.
For ease of viewing, fig. 1a provides a profile of support structure I and support structure II without a flexible light source; fig. 1b provides that the support structure I and the support structure II are covered by a flexible light source 50.
The control structure 60 may alternatively take the following forms:
1. as shown in fig. 1a and fig. 1b, a push cylinder 61 is sleeved outside the central shaft 10, the push cylinder 61 is fixedly connected with the end surface of the sliding sleeve 20, the end of the push cylinder 61 is exposed, when in use, the push cylinder 61 is provided with axial pushing force or pulling force to realize sliding control of the sliding sleeve 20, and further realize control of expansion and contraction of the supporting structure.
At this time, the power supply line 51 of the flexible light source 50 is disposed by being attached to the outer surfaces of the sliding sleeve and the push cylinder 61, and an adjustment margin 51-1 is provided at the joint of the sliding sleeve 20 and the support structure.
2. As shown in fig. 1c, the length of the sliding sleeve 20 extends along the length direction of the central shaft 10, and the direct end is exposed, when in use, the sliding control of the sliding sleeve 20 is realized by providing axial pushing force or pulling force to the exposed end of the sliding sleeve 20, so as to realize the control of the expansion and contraction of the supporting structure.
At this time, the power supply line 51 of the flexible light source 50 is arranged in such a way as to be attached to the outer surface of the sliding sleeve, and an adjustment margin 51-1 is provided at the joint of the sliding sleeve and the support structure.
In this embodiment, the flexible light source 50 is fixed on a flexible substrate 70, two sides of the flexible substrate are fixed on the adjacent support strips II41, and the middle of the flexible substrate is fixed on the support strip I31 between the two support strips II 41. When the support structures I and II are contracted, the flexible light source 50 is folded along the center line of the flexible substrate 70, and the folded flexible light source and the flexible substrate 60 can be curled by rotating the central shaft clockwise or counterclockwise; if the treatment is performed by clockwise curling, the flexible light source is turned on by rotating the central shaft 10 counterclockwise after entering the body.
In this embodiment, the flexible substrate 70 is a rubber sheet, the flexible light source is an OLED light source substantially conforming to the shape of the flexible substrate 70, and is fixed on the flexible substrate 70 by glue, and the edge of the flexible substrate 70 is fixed on the support structure by glue. In other embodiments, the flexible light source can also be a plurality of OLED light sources, LED light sources, quantum dot light sources, miniLED light sources, micro LED light sources, or optical fibers arranged on the flexible substrate 70, or a combination of any two or three of the above light sources.
In other embodiments, the flexible light source 40 is coated with a skin-friendly material layer, such as silica gel, Polydimethylsiloxane (PDMS), silica gel, Collagen (Collagen), Silicone Hydrogel (Hydrogel), Hydrogel (hydrocoloid), Polyurethane (PU), polymethyl methacrylate (PMMA), polymethylpentene polymer (PMP), Polyethylene (PE), polycarbonate, polystyrene, acrylonitrile butadiene styrene, polyolefin, polyamide, polyvinyl chloride, polyethylene, polypropylene, nylon, polyester, Silicone, polyimide, polytetrafluoroethylene, polyethersulfone, polysulfone, polyetheretherketone, chitosan, pectin, gelatin, nylon, fiber, and the like.
When adopting flexible light source to lay on bearing structure's surface, compare the mode of single fiber treatment among the prior art, because when the treatment, bearing structure is expanded, can be close to the focus area more, avoids the loss that liquid leads to. For example, some lesions such as bladder may sometimes block the lesion due to larger organs, and the whole bladder may be supported by filling liquid during treatment, and light loss may also be caused due to the presence of liquid, especially for the case of a single light guide fiber, the liquid needs to be transmitted from the end of the fiber to the lesion, and in this case, the light loss may be very serious; and in the technical scheme of this application, strut through bearing structure for the light source can be close to focus position more, and the distance that light permeates through liquid is shorter, and correspondingly, light loss also can be a lot less.
In this embodiment, the color of the flexible light source may be red light, blue-green light or blue light, or a light source with multiple mixed colors:
the irradiation depth of the yellow green light with the wave band of 510 nm-590 nm is between the blue light and the red light, so that the dredging and the expansion of the capillary vessel in the skin depth can be promoted, the resistance of cells is enhanced, and the treatment effect of the affected part is accelerated.
Red light with a waveband of 590-810 nm can enable mitochondria to release cytochrome c oxidase, increase adenosine triphosphate, and enable cells to provide energy by utilizing the adenosine triphosphate, so that the metabolism of the cells is promoted; meanwhile, the red light irradiation heats molecules in the blood vessel, so as to adjust the blood vessel expansion and improve the blood circulation;
the blue light irradiation of the 440-510 nm wave band can be used for relieving pain and swelling caused by inflammation. Therefore, the present embodiment can achieve a plurality of different therapeutic effects by arranging different light sources.
When the photomedical device provided by this embodiment is used for internal treatment, can send into the internal with bearing structure I and bearing structure II and flexible light source through promoting the center pin. The photomedical device provided by the embodiment can also be used for extracorporeal treatment, and local treatment can be performed by selectively electrifying part of the flexible light source.

In the embodiment, the length of the support strip I31 is basically consistent with that of the support strip II41, and the support structure I and the support structure II can form a circular outline after being unfolded, so that the flexible light sources are distributed more uniformly; after the supporting structure I and the supporting structure II are contracted, the sliding sleeve I21 and the sliding sleeve II22 are respectively and independently controlled, so that the sliding sleeve I21 can be retracted into the sliding sleeve II22 when being contracted, and the contraction degree of the supporting bar I31 relative to the supporting bar II41 is larger, thereby forming a wave-shaped adjusting contour.
In the embodiment, the sliding sleeve I21 is driven by a push cylinder I61-1, and the sliding sleeve II22 is driven by a push cylinder I61-2; the push cylinder I61-2 is sleeved outside the push cylinder I61-1;
example 3
In this embodiment, on the basis of embodiment 1, the implementation manner of the support structure I and the support structure II is changed as follows:
as shown in fig. 3a and 3b, the outer peripheral surface of the sliding sleeve 20 is rotatably provided with a plurality of circles of supporting columns along the length direction thereof, and each circle of supporting columns is formed by long supporting columns 32 and short supporting columns 42 which are distributed at intervals; all the long support columns 32 form the support structure I; all the short support columns 42 form the support structure II.
