The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the application.

A side-transmitting fiber 100 and a laser medical device according to an embodiment of the present application are described below with reference to fig. 1-10.

As shown in fig. 1,2 and 5, the side light-transmitting fiber 100 includes: a transparent sheath 110, a light guide 120, and a dispersoid 130.

As shown in fig. 1 and 2, the transparent sheath 110 is used as a support carrier for the light guide 120 and the dispersoid 130, and is used to wrap the light guide 120 and the dispersoid 130, and the transparent sheath 110 is protruded into a human body during medical operation, so that the transparent sheath 110 needs to have certain flexibility and strength, for example, the transparent sheath 110 can be made of medical polyethylene material.

As shown in fig. 1 and 2, the light guide 120, which is a light guide carrier for laser light, may be made of a core, a cladding, and a coating layer, by causing the laser light to be totally reflected in the direction of the core, which may be made of high purity quartz or quartz glass containing impurities, and guiding the light toward the dispersoid 130.

As shown in fig. 1 and 2, the caliber of the dispersoid 130 becomes smaller in the direction away from the light guide 120.

The dispersoid 130 is used as a scattering carrier of laser light and is used for scattering light to the periphery of the dispersoid 130, wherein the dispersoid 130 can be soft plastic material containing dispersoid, or can be other structures which can scatter light when the light passes along the dispersoid 130.

It should be noted that, the side-transmitting fiber 100 does not have the dispersoid 130, so that light is totally reflected along the side-transmitting fiber 100 and is transmitted out from the end of the side-transmitting fiber 100, and if the lesion is located on the side wall of the throat of the patient, the light cannot approach the lesion.

In the related art, the dispersion 130 is provided along the light guiding direction of the side light-transmitting fiber 100, the dispersion 130 is in a cylindrical structure, a part of light is transmitted along the dispersion 130, scattered around the dispersion 130, and another part of light is continuously transmitted along the dispersion 130 until the light is transmitted from the end of the dispersion 130, and the part of light cannot approach the focus, so that waste is caused, meanwhile, due to the waste of the part of light, the transmission power of the side light-transmitting fiber 100 is often required to be increased, and the light causes overheat of the side light-transmitting fiber 100 in the coupling transmission process, so that discomfort of human body is caused.

In the embodiment of the present application, the dispersoid 130 is designed into a structure with a caliber decreasing in the direction away from the light guide 120, so as to destroy the total reflection of light, scatter and refract the light when the light is transmitted along the dispersoid 130, and transmit the light from the periphery of the dispersoid 130, so that the transmission of laser from the end of the dispersoid 130 can be greatly reduced, the utilization rate of the laser is improved, the transmission power of the side-transmitting fiber 100 is indirectly reduced, and the overheating of the side-transmitting fiber 100 is avoided.

It should be noted that, the light guide 120 and the dispersoid 130 may be nested in the transparent sheath 110, the light guide 120 is disposed close to the dispersoid 130, and the end portions between the light guide 120 and the dispersoid 130 and between the dispersoid 130 and the transparent sheath 110 may be bonded by using transparent glue.

In some embodiments, as shown in fig. 2, the dispersion 130 includes a positioning segment 131 and a tapered segment 132, the positioning segment 131 is axially connected to the tapered segment 132, an outer sidewall of the positioning segment 131 is connected to an inner sidewall of the transparent sheath 110, and a caliber of the tapered segment 132 becomes smaller in a direction away from the positioning segment 131.

In this embodiment, the outer sidewall of the positioning section 131 is used to connect with the inner sidewall of the transparent sheath 110, so that the tapered section 132 can keep the same extension direction with the side light-transmitting fiber 100, and further ensure that the dispersoid 130 emits light uniformly.

In some examples, as shown in fig. 2, the end of the tapered section 132 distal from the locating section 131 is planar, which is connected to the end of the transparent sheath 110. Such a design can facilitate the securement of the tapered section 132 with the end of the transparent sheath 110.

In practical implementation, the positioning segment 131 and the tapered segment 132 may be vertebral bodies, or may be table bodies, or the positioning segment 131 is a cylinder, and the tapered segment 132 is a vertebral body, for example, the positioning segment 131 and the tapered segment 132 are both round tables, and the diameters of the positioning segment 131 and the tapered segment 132 are both smaller along the direction away from the light guide body 120, for example, the positioning segment 131 is a cylinder, and the tapered segment 132 is a round table.

In some examples, if the positioning segment 131 and the tapered segment 132 are both frustoconical, the angle between the generatrix of the positioning segment 131 and the tapered segment 132 and the inner wall of the transparent sheath 110 is 5 ° to 25 °, or if only the tapered segment 132 is frustoconical, the angle between the generatrix of the tapered segment 132 and the inner wall of the transparent sheath 110 is 5 ° to 25 °. This design can facilitate refraction of light out of the perimeter of the dispersion 130.

In some examples, the perimeter of the dispersion 130 may be roughened, for example, the perimeter of the locating segment 131 and the tapered segment 132 may be polished. The purpose of this design is to further disrupt the total reflection of the light, allowing more refraction of the light out around the dispersoid 130.
