Background

The flexible light source is changeable in shape, so that the flexible light source can be suitable for various occasions, such as indoor illumination, photodynamic therapy and the like. Photodynamic therapy, among others, is a method for treating diseases directly using light or using light and drug combination, and has been currently applied to clinical medicine. There are two main ways of photodynamic therapy, one is direct phototherapy and the other is the synergistic effect of light and a drug (also called photosensitizer). Photodynamic therapy is favored because of its advantages of good selectivity, minimal trauma, good tolerability, simple handling, etc. Photodynamic therapy can be classified into in vivo therapy and in vitro therapy, and in vivo therapy includes bladder cancer, throat cancer, bronchus cancer, and the like. The light source for in vivo treatment is mainly a laser optical fiber, and the optical fiber has the advantages of easy insertion into the body and small wound.

It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that, for convenience of description, only the portions related to the application are shown in the drawings.

It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.

Example 1

The present embodiment provides an photomedical device including:

The central axis 10 is provided with a central axis,

A sliding sleeve 20 slidably sleeved on the central shaft 10;

A support structure 30 fixed to the sliding sleeve 20 to form an adjustment profile around the end of the central shaft 10;

A flexible light source 40, fixed to said support structure 30, distributed along said adjustment profile, for providing a therapeutic light source;

the support structure 30 expands when the runner 20 is stressed to expand the flexible light source 40.

Wherein, in the present embodiment, the central shaft 10 is made of steel wire, thin deformable plastic rod or plastic tube, hollow or solid rubber tube; the end provided with the support structure 30 is used for stretching into the body for treatment, the other end is exposed outside the body, and the end exposed outside the body is provided with the control structure 50.

For ease of viewing, the contoured surface of the support structure 30 provided in FIG. 1a is not provided with a flexible light source; the support structure 30 provided in fig. 1b is covered by a flexible light source 40.

The control structure 50 may alternatively take the following form:

1. As shown in fig. 1a and 1b, the central shaft 10 is sleeved with a push tube 51, the push tube 51 is fixedly connected with the end surface of the sliding sleeve 20, and the end part of the push tube 51 is exposed.

At this time, the power supply line 41 of the flexible light source 40 is provided by attaching to the outer surfaces of the sliding sleeve and the push cylinder 51 in such a manner that an adjustment margin 41-1 is provided at the junction of the sliding sleeve 20 and the supporting 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 end portion is exposed directly, so that when the sliding sleeve is used, 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, and further the expansion and contraction control of the supporting structure 30 is realized.

At this time, the power supply line 41 of the flexible light source 40 is disposed in such a manner as to be attached to the outer surface of the sliding sleeve, and an adjustment allowance 41-1 is provided at the junction of the sliding sleeve and the supporting structure.

As shown in fig. 1a, in this embodiment, the support structure is in a grid sphere shape, the end of the central shaft 10 penetrates into the support structure 30 and is fixedly connected with the support structure, when the support structure 30 is pushed by the sliding sleeve 20 towards the end of the central shaft, a spherical surface is formed in the figure, so that the flexible light source fixed on the surface is unfolded; as shown in FIG. 1d, when an outward pulling force is provided to the sliding sleeve 20, the support structure 30 contracts, forming a rod shape, thereby facilitating removal from or entry into the body.

The "mesh spherical shape" in the present embodiment may be a perfect circular mesh spherical shape or an elliptical mesh spherical shape. The 'grid sphere' support structure in this embodiment is formed by a plurality of mutually hinged support bars connected.

In this embodiment, the flexible light source is attached to the surface of the flexible substrate 60, and the edge of the flexible substrate 60 is fixed on the support structure 30; when the support structure 30 is contracted, the flexible light source is folded along with the central line of the flexible substrate 60, and the central shaft is rotated clockwise or anticlockwise at this time, so that the folded flexible light source and the flexible substrate 60 can be curled; if the flexible light source is curled clockwise before treatment, the central shaft 10 is rotated anticlockwise after entering the body to turn on the flexible light source.

In this embodiment, the flexible substrate 60 is a rubber sheet, the flexible light source is an OLED light source having a shape substantially identical to that of the flexible substrate 60, and the OLED light source is fixed on the flexible substrate 60 by an adhesive, and the edge of the flexible substrate 60 is fixed on the support structure by an adhesive manner. In other embodiments, the flexible light source may be a plurality of OLED light sources, LED light sources, quantum dot light sources, miniLED light sources, microLED light sources, optical fibers, or a mixture of these light sources arranged on the flexible substrate 60.

In other embodiments, the flexible light source 40 is coated with a layer of skin-friendly material, such as silicone gel, polydimethylsiloxane (PDMS), silicone gel, collagen (Collagen), silicone gel (Silicone Hydrogel), hydrogel (Hydrogel), hydrocolloid (Hydrocolloid), 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.

The flexible light source is directly arranged on the surface of the supporting structure, and compared with the mode of single optical fiber treatment in the prior art, the loss on the path is avoided.

When the flexible light source is arranged on the surface of the supporting structure, compared with the single optical fiber treatment mode in the prior art, the supporting structure is unfolded during treatment, so that the supporting structure is closer to a focus area, and the loss caused by liquid light absorption is avoided. For example, some lesions are relatively large in organs such as bladder, and sometimes can block the affected part, and the whole bladder is supported by filling liquid during treatment, and light loss is caused by the existence of the liquid, especially in the case of a single optical fiber, the liquid needs to be transmitted from the end part of the optical fiber to the lesion, and the light loss is very serious; in the technical scheme of the application, the light source can be closer to the focus part by the supporting structure, the distance of light penetrating through the liquid is shorter, and correspondingly, the light loss is much smaller.

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 a mixture of colors:

The light irradiation depth of yellow green light with the wave band of 510 nm-590 nm is between blue light and red light, so that the dredging and the expansion of capillary vessels with the skin depth can be promoted, the resistance of cells can be enhanced, and the treatment effect of an affected part can be accelerated.

Red light with the wave band of 590-810 nm can lead mitochondria to release cytochrome c oxidase, increase adenosine triphosphate, and the cells provide energy by using the adenosine triphosphate, thereby promoting the metabolism of the cells; meanwhile, the red light irradiation heats molecules in blood vessels, regulates the vasodilation and improves the blood circulation;

Blue light irradiation in the 440-510 nm band can be used for relieving pain and swelling caused by inflammation. Therefore, the embodiment can achieve a plurality of different treatment effects by arranging different light sources.

When the photomedical device provided by the embodiment is used for in-vivo treatment, the supporting structure and the flexible light source can be sent into the body by pushing the central shaft. The photomedical device provided by this embodiment may also be used for extracorporeal treatment by selectively energizing portions of the flexible light source to effect localized treatment.

Example 2

The implementation manner of the supporting structure of this embodiment is replaced by the following manner on the basis of embodiment 1: as shown in fig. 2a, the supporting structure 30 is composed of a plurality of supporting bars 31 circumferentially distributed around the central shaft 10, one end of each supporting bar 31 is fixed at the end of the central shaft 10, and the other end is fixed on the sliding sleeve 20.

At this time, a shuttle-shaped space is formed between the adjacent support bars 31, and both sides of the flexible substrate 60 are fixed to the adjacent support bars 31.

The support bar 31 may be made of, for example, a plastic having a certain elasticity.

Example 3

As shown in fig. 3a, the difference between the present embodiment and embodiment 2 is: the flexible light source is replaced with: the flexible light sources are distributed along the length direction of the supporting bar 31, in this embodiment, the flexible light sources are LED beads 42, the supporting bar 31 is provided with a flat layer 43 covering all the flexible light sources, the flat layer is made of organic materials, such as PMMA, parylene, etc., and the thickness of the flat layer is 10 μm-50 μm higher than that of the light sources.

At this time, as shown in fig. 3b, optical fibers 44 may be attached to the supporting bar 31 along the length direction thereof;

Alternatively, an OLED light source may be attached to the support bar 31 along the length direction thereof;

The number of the flexible light sources is multiple, and the flat layers 43 enable the lamp strip to be flat through parallel or serial circuit connection, so that comfort in use is improved.

As shown in fig. 3c, the light strips 45 may also be preferably arranged circumferentially.

Example 4

As shown in fig. 4a and 4b, this embodiment differs from embodiment 1 in that, on the basis of embodiment 1, it is: the fixing mode of the flexible light source is changed into a flexible woven structure, wherein the flexible light source is fixed on a lamp strip, and in the embodiment, as shown in fig. 4a, the lamp strip comprises a transverse lamp strip 45-1 and a longitudinal lamp strip 45-2; the transverse light strip 45-1 and the longitudinal light strip 45-2 are woven on the supporting structure 30, and the transverse light strip 45-1 and the longitudinal light strip 45-2 may be made of thin rubber sheets, for example.

In this embodiment, the light sources are LED beads, and are connected by parallel or serial circuits, and the horizontal light strip 45-1 and the vertical light strip 45-2 are provided with a flat layer 43 covering all the light sources 40, and the flat layer is made of an organic material, such as PMMA, parylene, etc., and has a thickness 10 μm-50 μm higher than that of the light sources. The flat layer 43 allows the strip to be relatively flat, improving comfort during use.

In other embodiments, the LED lamp beads can be replaced by optical fibers or OLED light sources, and the optical fibers are attached to the transverse lamp strip 45-1 and the longitudinal lamp strip 45-2 along the length direction;

The light-emitting area of the single light strip is smaller, and the light-emitting area of the braided light strip is larger than that of the single light strip; since the lamps arranged throughout the strip are independent individuals with consistent illumination, the overall braided strip form will have better illumination uniformity relative to a massive, monolithic flexible light source; because the part of the large-block flexible light source far away from the bonding area emits light with darker brightness, and the part near the bonding area emits light with brighter brightness.

Example 5

This example differs from example 1 on the basis of example 1 in that: the flexible light source is attached to the surface of a flexible substrate 60, the edges of which are secured to the support structure 30.

As shown in fig. 5a, a row of connection ribs is fixed on the bottom surface of the flexible substrate 60 perpendicular to the central axis 10.

Therefore, when the supporting structure is contracted, the situation that the flexible light source is damaged due to complete folding can be avoided at the folding position of the flexible light source, and particularly for the whole OLED light source, the bending angle of the connecting ribs is increased.

In other embodiments, as shown in fig. 5b, the effect of expanding the folding angle of the connecting rib may also be achieved by providing a greater thickness in the middle of the flexible substrate 60 along the length direction.

The movement stop position of the slide sleeve 20 can be realized by providing a protrusion for limiting the movement of the slide sleeve on the central shaft, or by providing a structure for limiting the rotation position of the support column 32 on the side surface of the slide sleeve.

Preferably, the length of each circle of support columns 32 can be gradually increased from the two ends of the sliding sleeve to the middle part, so that an oval or circular profile surface is realized.

In other embodiments, as shown in fig. 6d, the number of sliding sleeves may be plural, and plural sliding sleeves 20 are disposed in linkage; a circle of support columns 32 are hinged to the side face of each sliding sleeve.

In this embodiment, by designing the support columns 32 in a plurality of circles, the outline shape of the support structure is convenient to control, and the shape of the final support structure can be controlled by designing the length of the support bar so as to adapt to different treatment requirements.
