Description

Technical Field

[0001] The present invention relates to a phototherapy device, in particular to a light-guiding component and a phototherapy terminal for sinus tract treatment, belonging to the technical field of phototherapy instruments. Background Art

[0002] Sinus refers to a potential blind tube that opens to the body surface and does not communicate with the hollow organs in the body after the body tissue is infected, necrotic and discharged from the body surface. It can occur in soft tissue, fat, muscle and even bone. Common sinus include: abdominal wall sinus caused by poor drainage after infection of abdominal wall incision or foreign body left in the incision; chronic sinus caused by bone necrosis due to fracture or other reasons; chronic sinus caused by foreign body residue after trauma or surgery, etc.

[0003] Red light has anti-inflammatory, anti-swelling, analgesic and antipruritic effects, can relieve muscle spasms, promote tissue regeneration, promote wound and ulcer healing, relieve pain, etc., so red light can be used for sinus treatment. Currently, there is no phototherapy device dedicated to sinus treatment on the market. Some medical staff use conventional red light phototherapy devices for skin irradiation to directly irradiate the surface of the sinus, or use bare optical fiber to introduce sinus irradiation treatment.

[0004] The method of directly irradiating the surface of the sinus tract has the following defects: when red light irradiates the surface of the sinus tract, due to the poor penetration of light, most of the light will be reflected and absorbed by the surface, and it is difficult to enter the interior of the sinus tract. The light energy utilization rate is low and the treatment effect is poor.

[0005] The method of using optical fiber for irradiation has the following defects: when the bare optical fiber emits a light beam, its output end is relatively small and has a relatively small divergence angle, which will cause the light energy to be concentrated in a certain part of the sinus tract, resulting in uneven irradiation and failure to treat other parts of the sinus tract. In addition, the optical fiber head needs to be disinfected each time for invasive irradiation, which is time-consuming and difficult to handle.

[0006] Therefore, those skilled in the art are committed to developing a phototherapy instrument specifically for sinus tract treatment. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a phototherapy terminal for sinus tract irradiation, which can penetrate deep into the sinus tract and evenly transmit light energy to the surface of the tissue inside the sinus tract.

Words such as "including" or "having" and similar terms mean that the elements or objects appearing before "including" or "having" include the elements or objects listed after "including" or "having" and their equivalent elements, and do not exclude other elements or objects.

[0063] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0064] In the description of this patent, it should be understood that the terms "upper", "lower", "left", "right", "horizontal", "lateral", "longitudinal", "top", "bottom", "inside", "outside", "clockwise", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing this patent and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0065] Different embodiments of the present invention may be replaced or combined, so the present invention may also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, the present invention should also be considered to include embodiments containing one or more of A, B, C, and D, all other possible combinations, even though the embodiment may not be clearly described in the following text.

[0066] The present invention provides a phototherapy terminal for sinus tract phototherapy, which is mainly composed of a light guide component and an optical adapter. The optical adapter can adopt a standard optical fiber coupling connector, such as a standard SMA905 or FC connector. One end of the optical adapter is connected to the optical fiber, and the other end is connected to the light guide component. The light guide component is a specially designed light guide lens structure that can evenly transmit the light energy derived from the optical fiber to the surface of the internal tissue of the sinus tract. Preferably, the light guide component is detachably connected to the optical adapter, so that the light guide component can be used as a disposable.

[0067] The light guide component is made of materials such as acrylic, PC (polycarbonate), quartz, optical glass, etc., and can transmit visible light such as red light. The main body of the light guide component is a smooth-surfaced column, preferably a cylinder, with a diameter of 2 to 4 mm and a length of 10 to 15 mm. The light guide component can also be other columns. For example, a column similar to a hexagonal prism, but the edges are rounded.

[0068] The side surface of the cylindrical light-guiding component is provided with a recessed portion, which may include but is not limited to: pits of various shapes (for example, hemispherical pits, conical pits, frustum-shaped pits, etc.) and / or grooves of various shapes (for example, annular grooves, spiral grooves), etc. The recessed portion is preferably a circular groove. The groove cross-section may be flat-bottomed, semicircular, arc-shaped, etc., and the effect of a semicircular groove is better. The radius (or arc height) of the groove is less than 1 / 6 of the diameter of the cylinder to ensure that the light-guiding component as a whole is not easy to break. The number, position and size of the grooves vary to meet different sinus irradiation requirements. Limited by the size of the cylinder and the spacing requirements between the grooves, the number of grooves generally does not exceed 10.

[0069] Considering that the light guide component will enter the sinus tract during use, the edges of the grooves are preferably rounded or chamfered to reduce scratching and stimulation to human tissue in the sinus tract. The width of the protrusion between two adjacent annular grooves is greater than 0.3 mm. The width of the edge of the frontmost annular groove adjacent to the front end surface and the front end surface is greater than 0.3 mm. If the above two dimensions are less than 0.3 mm, the protrusion of the light guide component will become very sharp and may scratch human tissue in the sinus tract.

[0070] The tail end of the light guide component is connected to the optical adapter, and its shape matches the connection position of the optical adapter. The front end surface of the conduit component is flat. The light entering the light guide component can be scattered from the side surface and the front end surface of the columnar body. The light guiding effect of the main body of the light guide component is similar to that of a common light guide column. The groove refracts part of the light from the side surface of the light guide component, and the annular groove can radiate the light to all sides. The front end surface of the light guide component is required to be flat so that the light emitted from the front end surface is not convergent.

[0071] The specific embodiments are further described in detail below with reference to the accompanying drawings.

[0072] Example 1

[0073] The phototherapy terminal provided in this embodiment is as follows: Figure 1 As shown in FIG. 1 , the light therapy terminal is composed of a light guide component 100 and an optical adapter 500. The optical adapter 500 is as shown in FIG. Figure 2 As shown, one end of the optical adapter 500 has a recessed connection position 510. The tail end of the light guide component 100 is inserted into the connection position 510, and the two realize optical path communication. The other end of the optical adapter 500 has a recessed connection position 520, as shown in FIG. Figure 4 The optical fiber is inserted into the connection position 520. In this embodiment, the optical adapter 500 is SMA905.

[0074] The light guide component 100 is made of quartz. The body of the light guide component 100 is a cylinder with a diameter of 3 mm and a length of 15 mm. Four round-bottomed annular grooves are arranged in sequence along the axial direction of the cylinder: a round-bottomed annular groove 120, a round-bottomed annular groove 130, a round-bottomed annular groove 140, and a round-bottomed annular groove 150. The groove cross-sections of the four grooves are all semicircular, and the radius of the semicircle is about 0.5 mm. The two edges of the round-bottomed annular groove 120 are respectively provided with groove fillets 121 and groove fillets 122. The front end face 110 of the light guide component 100 is flat to avoid the convergence of light. The edge of the front end face 110 has an end face fillet 111. The width of the protrusion 170 between the round-bottomed annular groove 120 and the round-bottomed annular groove 130 is about 0.4 mm. The width of the protrusion 160 is about 0.3 mm.

[0075] The optical path schematic diagram of the light guide component 100 is shown in FIG. Figure 3The light incident into the light guide component 100 from the rear end thereof is reflected and refracted multiple times and then uniformly emitted from the side surface and the front surface thereof.

[0076] Example 2

[0077] In the first embodiment, the front end surface 110 of the light guide component 100 is flat, and the resistance is relatively large when inserted into the sinus, which may cause discomfort to the patient.

[0078] The phototherapy terminal provided in this embodiment is as follows: Figure 4 As shown, a guide sleeve 600 is installed at the front end of the light guide component 100, which is an improvement of the light therapy terminal provided in Example 1. The structural details of the guide sleeve 600 are as follows: Figure 5 As shown, the guide sleeve 600 is composed of a top 610, a body 620, and a tail 630, and gradually becomes thicker from the top to the tail. The top 610 is a curved surface, the body 620 is a truncated cone, and the tail 630 is a cylindrical shape. The guide sleeve 600 is a thin-walled shell made of acrylic, and the shell thickness is the same everywhere, so that a cavity 640 is formed inside the guide sleeve 600, and the light passing through the guide sleeve 600 follows the original direction without convergence. The guide sleeve 600 can also be made of the same material as the light guide component 100, that is, quartz is used to make the guide sleeve 600. But quartz is brittle and hard, because it is a thin-walled device, which increases the manufacturing cost.

[0079] Example 3

[0080] The phototherapy terminal provided in this embodiment is as follows: Figure 6 As shown in FIG. 1 , the light therapy terminal is composed of a light guide component 200 and an optical adapter 500. The optical adapter 500 is shown in FIG. Figure 2 As shown, the optical adapter 500 has a connection position 510 and a connection position 520. The tail end of the light guide component 200 is inserted into the connection position 510, and the optical fiber is connected to the connection position 520, and the optical path of the optical fiber and the light guide component 200 is connected by the optical adapter 500. In this embodiment, the optical adapter 500 uses an FC connector.

[0081] The light guide component 200 is made of acrylic. The main body of the light guide component 200 is a cylinder with a diameter of 4 mm and a length of 15 mm. Six grooves including a flat-bottomed annular groove 210 and a flat-bottomed annular groove 220 are sequentially arranged along the axial direction of the cylinder. The bottoms of these grooves are flat and the side walls are straight, which is different from the light guide component 100 in Example 1.

[0082] The front end of the light guide component 200 is also covered with a guide sleeve 600, which is also made of acrylic. The shape and function of the guide sleeve 600 are described in Example 2 and will not be repeated here.

[0083] Example 4

[0084] The phototherapy terminal provided in this embodiment is as follows: Figure 7 As shown, the phototherapy terminal is composed of a light guide component 300, a guide sleeve 600 and an optical adapter 500. In this embodiment, the optical adapter 500 is SMA905.

[0085] The light guide component 300 is made of optical glass, and the guide sleeve 600 is made of polycarbonate. The main body of the light guide component 300 is a cylinder with a diameter of 4 mm and a length of 15 mm. The spiral groove 310 spirals along the side surface of the cylinder.

[0086] Example 5

[0087] The phototherapy terminal provided in this embodiment is as follows: Figure 8 As shown, the phototherapy terminal is composed of a light guide component 400, a guide sleeve 600 and an optical adapter 500. In this embodiment, the optical adapter 500 adopts an FC connector.

[0088] The light guide component 400 and the guide sleeve 600 are both made of polycarbonate. The body of the light guide component 400 is a cylinder with a diameter of 2 mm and a length of 10 mm. The shape of the light guide component 400 in this embodiment is different from that of the guide components provided in other embodiments. The side surface of the light guide component 400 is completely smooth without any grooves or pits.

[0089] In order to allow more light to be scattered from the side surface of the light guide component 400, rather than just directly from the front face, a hollow position can be set in the light guide component 400. The inside of the hollow position is air, and due to the different refractive indices of light in glass and air, the propagation direction of the light changes at the interface between the two. The light entering the light guide component 400 is repeatedly refracted through these interfaces, and the accumulation of refraction causes a significant change in the direction of the light path, and finally scatters from the side surface of the light guide component 400. Regarding the formation of the hollow position, a simpler method is to foam a small amount of the inside of the polycarbonate when it is molded.

[0090] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
