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.

Thirdly, one notch 231 can be arranged at one end of the male head 210 close to the female head 220, and the other notch 231 is arranged at the bottom end of the female head 220, so that the bare head 140 can be fastened in the notch 231, and the current quick-disassembly side-penetration optical fiber 100 can be achieved.
In practical implementation, the crimping pieces 240 are connected in the notch 231, so that the distance difference between the bare head 140 and the male head 210 and/or the female head 220 can be compensated by one crimping piece 240, the other crimping piece 240 can be in threaded connection with the notch 231, and one end of the crimping piece 240 away from the notch 231 is positioned outside the notch 231, so that the crimping piece 240 is designed to be easy to detach.
In practice, the spring may be mounted in a slot 231 in which the crimp 240 is located, which may allow for a tighter connection of the components of the installer 200 (not shown in the figures).
In some examples, as shown in fig. 7 and 8, the installer 200 further includes a connection ring 250.
The male head 210 has a shoulder 211 near the female head 220, the connecting ring 250 has a bearing 251 at one end for receiving the shoulder 211, and the other end of the connecting ring 250 is screwed with the female head 220. This is designed to facilitate the detachable connection of the male 210 and female 220.
In some examples, as shown in fig. 9 and 10, the installer 200 further includes an end cap 212.
The end cap 212 is screwed on the male head 210, and at least one installation position connected with the medical equipment body is arranged on the end cap 212.
In actual practice, the mounting locations may be mounting holes or other mounting members.
The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application, wherein like reference numerals are used to refer to like elements throughout. Therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
