By means of the arrangement, the automatic detection mechanism for the optical fiber end face realizes the automatic detection of the to-be-detected end face 1100 of the optical fiber 1000, improves the detection efficiency, reduces the detection difficulty, avoids the detection omission, and prevents the optical fiber 1000 with unqualified end face from being connected to laser treatment equipment, thereby causing the damage of the laser treatment equipment and even affecting the life safety of patients.

Wherein, the included angle between the axis L1 of the detection lens 210 and the axis L2 of the end face 1100 to be detected is A, and 0 DEG < A < 90 deg. The above-mentioned angle arrangement ensures that the laser light reflected from the end surface 1100 to be inspected is deviated from the path of the laser light emitted from the emitting assembly 2000 after being reflected by the inspection lens 210, so that there is enough space for installing the inspection piece 220.

Specifically, the angle between the axis L1 of the detection lens 210 and the axis L2 of the end face 1100 to be detected is a, and a=45°. This arrangement allows the connection between the sensing element 220 and the sensing lens 210 to be perpendicular to the laser light emitted from the emitting assembly 2000, facilitating the mounting of the sensing element 220. In this embodiment, the transmittance of the detection lens 210 is greater than 99%, so as to avoid excessive loss of laser and reduce the influence on the operation.

The detecting member 220 judges whether or not the end face 1100 to be inspected is normal by detecting the power of the laser light reflected from the end face 1100 to be inspected. If the surface 1100 to be inspected is uneven, less reflected laser light will be caused, and the power detected by the detecting member 220 will be smaller. It should be noted that the structure and the working principle of the detecting element 220 are well known to those skilled in the art, and thus are not described herein.

The automatic optical fiber end face detection mechanism comprises a detection bracket 230, wherein the detection bracket 230 is fixed on the mounting seat 100, and the detection lens 210 and the detection piece 220 are both arranged on the detection bracket 230.

In this embodiment, the angle B between the detection platform 232 and the detection plate 231 is 45 °. The arrangement allows the detection platform 232 to be horizontal and the detection member 220 to be placed horizontally. In the present embodiment, the angle between the axis L1 of the detection lens 210 and the axis L2 of the end surface to be detected 1100 is a, and a=45°. With the above-mentioned angle setting, the detecting member 220 is located at the center of the laser light reflected by the detecting lens 210, and may face the laser light to collect the energy of the laser light as much as possible.

In this embodiment, the detecting platform 232 is provided with a second detecting hole, the detecting member 220 is disposed on one side of the detecting platform 232 away from the detecting plate 231, and the detecting portion 221 of the detecting member 220 is disposed in the second detecting hole. With this arrangement, the first aspect allows the outer periphery of the detection portion 221 to be protected from damage caused by impact of an external object; the second aspect protects the other parts of the detecting member 220 except the detecting portion 221 from the laser light by the detecting platform 232; the third aspect avoids interference of other parts of the detecting member 220 on the laser, and improves the detection accuracy.

The mounting portion 233 has a plate-like structure, and the mounting portion 233 is perpendicular to the detection platform 232. The mounting portion 233 is provided with a fixing hole through which a mounting screw passes and is screwed into the mounting seat 100.

The automatic optical fiber end face detection mechanism comprises a flange 1200, the mounting seat 100 is provided with a through hole 110, and the optical fiber 1000 is mounted in the through hole 110 through the flange 1200.

Example two

The embodiment also provides a laser treatment device, which comprises laser treatment equipment, an emission component 2000, an optical fiber 1000 and an optical fiber end face automatic detection mechanism in the scheme, wherein the optical fiber 1000 is used for transmitting laser emitted by the emission component 2000 to the laser treatment equipment, and the optical fiber end face automatic detection mechanism is used for detecting an end face 1100 to be detected of the optical fiber 1000. With the above arrangement, the purpose of detecting the end face 1100 to be detected of the optical fiber 1000 in real time can be achieved, and the safety of the laser treatment device is improved.

In this embodiment, the emitting assembly 2000 includes a condensing cavity 2100, a full-return lens 2200, and a half-return lens 2300, and the condensing cavity 2100, the full-return lens 2200, and the half-return lens 2300 constitute a resonant cavity capable of emitting laser light. The working principle of lasing a resonant cavity is well known to those skilled in the art and is not important to the present utility model, and thus is not described in detail herein as an important point.

The emission assembly 2000 includes a coupling lens 2400, where the coupling lens 2400 is disposed between the resonant cavity and the optical fiber 1000, and is configured to focus laser light onto the end surface 1100 to be inspected of the optical fiber 1000.

In use, the resonant cavity can emit pulsed laser light which is focused onto the end face 1100 of the optical fiber 1000 to be inspected through the coupling lens 2400 and then transmitted to the focal site of the patient through the optical fiber 1000 for corresponding treatment.

Before laser enters the optical fiber 1000, the laser passes through the detection lens 210, the transmittance of the detection lens 210 is greater than 99%, most of the laser can be transmitted to a focus through the optical fiber 1000, a small amount of laser is reflected back on the end face 1100 to be detected of the optical fiber 1000, the reflected laser is reflected along the direction perpendicular to the original laser direction when passing through the detection lens 210, the detection piece 220 is arranged on the optical path of the reflected light, the detection piece 220 is a power detection probe, and the power of the laser returned by the end face 1100 to be detected can be detected, so that whether the end face of the optical fiber 1000 is qualified or not is judged.

When the optical fiber 1000 is connected to the laser treatment device, the user clicks the preparation button each time to prepare to emit laser, the resonant cavity emits a detection laser first, and the detection laser is detected by the detecting member 220 and then outputs a detection value, so as to determine whether the end face 1100 to be detected is qualified. Specifically, the method of judging is to compare the detected value with a preset value, if the detected value is within the interval of the set value, the detected end face 1100 is qualified, the optical fiber 1000 can be used normally, and if the detected value is smaller than the set value, the detected end face 1100 of the optical fiber 1000 is abnormal, and the user is prompted to replace the optical fiber 1000.

In an embodiment, the detection support 230 is slidably disposed on the mounting base 100, and can slide between a detection position and an avoidance position, and the mounting base 100 in the detection position places the detection lens 210 in a reflection position, that is, the laser energy emitted from the emission component 2000 passes through the detection lens 210, and the laser energy reflected from the end face 1100 to be detected is reflected by the detection lens 210 to the detection member 220. The mounting seat 100 at the avoiding position positions the detection lens 210 at the recovery position, and at this time, the detection lens 210 is positioned outside the laser emitted by the emission assembly 2000, that is, the laser emitted by the emission assembly 2000 does not pass through the detection lens 210, so that the loss of laser energy in the operation process is avoided.

In one embodiment, the detection support 230 is moved to the detection position prior to starting the procedure and moved to the avoidance position after the detection is completed. In one embodiment, the detection support 230 moves to the detection position for detection every preset time period, and moves to the avoidance position after detection is completed.
