[0003] In the prior art, medical optical fiber couples the laser output by the laser into the optical fiber through a coaxial connector (SMA end). During this process, the laser energy is transmitted to the ceramic ferrule through the optical fiber. Although the ceramic material is resistant to high temperatures, it is not easy to dissipate heat. During the laser output process, the energy is concentrated on the ceramic ferrule, which often causes the ceramic ferrule to break. The ceramic ferrule often breaks in the coupler, and the coupling mirror must be replaced and the coupling must be readjusted. The process is cumbersome and requires a special engineer to go to the hospital for repair, which is expensive and causes inconvenience to the use of medical laser optical fiber and the doctor's surgery.

On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and complete, and to fully convey the scope of the disclosure of the present application to those skilled in the art.
[0025] In this embodiment, Figures 1 to 4 shown.
[0026] An embodiment of the utility model provides a medical optical fiber with a metal-embedded ceramic ferrule. The medical optical fiber includes a coaxial connector 7. The coaxial connector 7 includes a metal-embedded ceramic ferrule 6. The metal-embedded ceramic ferrule 6 includes a ceramic ferrule 61 and a metal shell 62. The metal shell 62 is attached to the outer side of the ceramic ferrule 61.
[0027] Furthermore, the ceramic ferrule 61 is wrapped in the metal shell 62 .
[0028] Furthermore, the outer diameter of the metal-embedded ceramic ferrule 6 remains unchanged.
[0029] Furthermore, the outer diameter of the metal embedded ceramic ferrule 6 is the sum of the outer diameter of the ceramic ferrule 61 and the thickness of the metal shell 62. The metal embedded ceramic ferrule 6 has the same outer diameter as the original ceramic ferrule, and the metal thickness can be thickened or thinned accordingly according to the process.
[0030] Furthermore, the medical optical fiber also includes an optical fiber 1 and a medical optical fiber handle 8 , and the optical fiber 1 passes through the SMA end of the coaxial connector 7 and the axial center of the medical optical fiber handle 8 .
[0031] Furthermore, the coaxial connector 7 further comprises a coaxial connector joint sleeve 2 and a coaxial connector handle 3. The coaxial connector joint sleeve 2, the coaxial connector handle 3 and the metal-embedded ceramic ferrule 6 are assembled together.
[0032] Furthermore, the coaxial connector joint sleeve 2, the coaxial connector handle 3 and the metal-embedded ceramic ferrule 6 are assembled together through threads.
[0033] Furthermore, the coaxial connector 7 further comprises a coaxial connector dust cap 5 , and the coaxial connector dust cap 5 covers the metal-embedded ceramic ferrule 6 .
[0034] Furthermore, the coaxial connector dust cap 5 covers the optical fiber 1 .
[0035] Furthermore, the medical optical fiber comprises a metal-embedded ceramic ferrule 6 , and the metal-embedded ceramic ferrule 6 is resistant to high temperatures and avoids breaking.
[0036] like Figure 2 As shown, Figure 1 The SMA end 7 of the overall structure of the medical optical fiber shown, that is, the overall structure diagram of the SMA end of the medical optical fiber after assembly, is a connector connecting the laser coupling end and the optical fiber.
[0037] like Figure 3 As shown, Figure 2 The exploded view of the SMA end of the medical optical fiber is shown. The SMA end structure includes an optical fiber 1, an SMA connector sleeve 2, an SMA handle 3, a metal-embedded ceramic ferrule 6, and an SMA dust cap 5. The optical fiber 1 passes through the axial center of the SMA as a whole. The SMA connector sleeve 2, the SMA handle 3 and the metal-embedded ceramic ferrule 6 are assembled together by threads. The dust cap 5 prevents dust from entering the SMA connector and the inside of the optical fiber to cause contamination.

The metal-embedded ceramic ferrule 6 is obtained by adding metal material to the outer contour of the ceramic ferrule 61 in the prior art to connect and fix the ceramic ferrule.
[0039] The laser output by the laser is coupled into the optical fiber through the SMA end. During this process, the energy of the laser is transmitted to the ceramic ferrule through the optical fiber. Although the ceramic material is resistant to high temperatures, it is not easy to dissipate heat. During the laser output process, the energy is concentrated on the ceramic ferrule, and the ceramic ferrule often breaks. The ceramic ferrule often breaks in the coupler, and the coupling mirror must be replaced and the coupling must be readjusted. The process is cumbersome and requires a special engineer to go to the hospital for repair.
