Description

Photo-medical device

Technical Field

The present disclosure relates generally to the field of photomedical technology, and more particularly to a photomedical device.

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. In vivo treatment includes bladder cancer, throat cancer, bronchial cancer, etc. 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. However, the optical fiber has large light energy loss and poor light emitting uniformity, and the light energy irradiated to the focus through the optical fiber is relatively low in the treatment process of a large organ, which is unfavorable for photodynamic therapy.

Detailed Description

The application is described in further detail below with reference to the drawings and examples. 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

Referring to fig. 1, the present embodiment provides an optical medical device, including:

The central axis 10 is provided with a central axis,

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

a support structure I and a support structure II are fixed on the outer surface of the sliding sleeve 20;

An adjustment profile jointly formed by the support structures I and II, 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 sources 50 are distributed along the adjustment profile for providing a therapeutic light source;

the support structures I and II expand when the sliding sleeve 20 is stressed to expand the flexible light source 50; the support structures I and II contract such that the adjustment profile becomes wavy.

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 part provided with the supporting structure I and the supporting structure II is used for stretching into the body for treatment, the other end of the supporting structure I and the supporting structure II is exposed out of the body, and the end part exposed out of the body is provided with a control structure.

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 bar I31 is fixed at the end part 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 bar II41 is fixed at the end part of the central shaft 10, and the other end is fixed at the lower part of the sliding sleeve 20;

The supporting bars I31 and the supporting bars II41 are circumferentially distributed at intervals.

The supporting bar I31 and the supporting bar II41 can also be made of steel wires, thin deformable plastic bars or plastic tubes, hollow or solid rubber tubes. Wherein, the support bar I31 is connected with the flexible light source 50 only at the middle part of the length direction; since support bar I31 is shorter than support bar II41, the spherical profile formed thereby is within the spherical profile formed by support bar II41, and when flexible light source 50 is disposed on both support bar I31 and support bar II41 and support structure I and support structure II are deployed, the ends of support structure II form a spherical or ellipsoidal profile along with which flexible light source 50 is deployed; when the support structures I and II shrink, as shown in fig. 1d, a wavy adjustment profile is formed, and the flexible light source 50 forms a wavy surface, so that the flexible light source 50 between two adjacent support bars II41 is prevented from being damaged due to an excessively large folding angle when shrinking, and the flexible light source 50 is protected.

For ease of viewing, the contoured surfaces of support structure I and support structure II provided in fig. 1a are not provided with flexible light sources 50; the support structures I and II provided in fig. 1b are covered by a flexible light source 50.

The control structure may alternatively take the following form:

1. As shown in fig. 1a and 1b, the central shaft 10 is sleeved with a push tube 61, the push tube 61 is fixedly connected with the end surface of the sliding sleeve 20, and the end part of the push tube 61 is exposed.

At this time, the power supply line 51 of the flexible light source 50 is provided by attaching to the outer surfaces of the sliding sleeve 20 and the push barrel 61 in such a manner that an adjustment margin 51-1 is provided at the junction of the sliding sleeve 20 and the support structure.

2. As shown in fig. 1c, the length of the sliding sleeve 20 extends along with 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 for the exposed end of the sliding sleeve 20, and further the control of the expansion and contraction of the supporting structure is realized.

At this time, the power supply line 51 of the flexible light source 50 is attached to the outer surface of the sliding sleeve 20 in such a manner that an adjustment margin 51-1 is provided at the junction of the sliding sleeve 20 and the supporting structure.

In this embodiment, the flexible light source 50 is fixed on a flexible substrate, two sides of the flexible substrate are fixed on the adjacent support bars II41, and the middle part of the flexible substrate is fixed on the support bar I31 between the two support bars II 41. When the support structures I and II shrink, the flexible light source 50 is folded along with the central line of the flexible substrate, and the central shaft 10 is rotated clockwise or anticlockwise at this time, so that the folded flexible light source 50 and the flexible substrate 60 can be curled; if the flexible light source 50 is turned on before treatment, after entering the body, the central shaft 10 is rotated counterclockwise.

In this embodiment, the flexible substrate is a rubber sheet, and the flexible light source 50 is an OLED light source substantially conforming to the shape of the flexible substrate, and is fixed on the flexible substrate by adhesive, and the edge of the flexible substrate is fixed on the supporting structure by adhesive. In other embodiments, the flexible light source 50 may be a plurality of OLED light sources, LED light sources, quantum dot light sources, miniLED light sources, microLED light sources, or optical fibers arranged on a flexible substrate, or a combination of any two or three of the foregoing.

In other embodiments, the flexible light source 50 is overcoated with a layer of skin-friendly material, such as a material of 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.

When the flexible light source 50 is disposed on the surface of the support structure, the support structure is deployed closer to the focal zone than in the single fiber treatment of the prior art, thereby avoiding loss due to liquid. 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 50 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 according to the present embodiment is used for in vivo treatment, the support structures I and II and the flexible light source 50 can be introduced into the body by pushing the central shaft 10. The photomedical device provided in this embodiment may also be used for extracorporeal treatment by selectively energizing portions of the flexible light source 50 to effect localized treatment.

Example 2

As shown in fig. 2a and 2b, in this embodiment, based on embodiment 1, the sliding sleeve 20 includes a sliding sleeve I21 slidably sleeved outside the central shaft 10, and a sliding sleeve II22 slidably sleeved outside the sliding sleeve I21; the support structure I consists of a plurality of support bars I31, and the support structure II consists of a plurality of support bars II 41;

One end of the supporting bar I31 is fixed at the end part of the central shaft 10, and the other end of the supporting bar I is fixed at the top of the sliding sleeve I21;

And one end of the supporting bar II41 is fixed at the end part of the central shaft 10, and the other end of the supporting bar II is fixed on the outer surface of the sliding sleeve II 22.

Wherein, a plurality of grooves are arranged at intervals on the top end of the sliding sleeve II22 corresponding to the supporting bar I31. In this embodiment, the lengths of the supporting bar I31 and the supporting bar II41 are substantially identical, and after the supporting structures I and II are unfolded, a circular outline can be formed, so that the flexible light source 50 is more uniformly distributed; after the supporting structure I and the supporting structure II shrink, the sliding sleeve I21 and the sliding sleeve II22 are controlled independently, so that the sliding sleeve I21 can shrink into the sliding sleeve II22 when shrinking, and the supporting bar I31 shrinks to a larger degree relative to the supporting bar II41, thereby forming a wavy adjusting profile.

In this embodiment, the sliding sleeve I21 is driven by the first pushing cylinder 61-1, and the sliding sleeve II22 is driven by the second pushing cylinder 61-2; the second pushing barrel 61-2 is sleeved outside the first pushing barrel 61-1;

Example 3

The implementation manner of the support structure I and the support structure II in this embodiment is changed to:

As shown in fig. 3a and 3b, the outer peripheral surface of the sliding sleeve 20 is rotatable along the length direction thereof to form a plurality of circles of support columns, and each circle of support columns is formed by a long support column 32 and a short support column 42 which are distributed at intervals; all long support columns 32 form the support structure I; all short support columns 42 form the support structure II.

At this time, wavy profile surfaces are formed when the support structure I and the support structure II are expanded and contracted.

Example 4

In the technology of embodiment 1, the arrangement mode of the flexible light source 50 is replaced by a structure of a woven light band, in this embodiment, as shown in fig. 4a, the light band comprises a transverse light band 45-1 and a longitudinal light band 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, and the flat layer 43 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 individual and have uniform illumination, the overall braided strip form will have better illumination uniformity relative to the bulk of the flexible light source 50; because the bulk flexible light source 50 emits light more darkly at locations away from the bonding region, it emits light more brightly at locations closer to the bonding region.
