Description

Technical Field

[0001] The invention relates to the technical field of laser equipment, and in particular to a medical laser equipment compatible with single pulse and double pulse modes. Background Art

[0002] Existing medical lasers rely on the absorption of lasers by lasers and water in tissues, mostly for thermal effects, such as stone crushing and cutting. When crushing stones, the water on the surface of the stones absorbs the laser energy and produces a blasting effect after heating up. The effect of lasers in the same band depends on the pulse energy and pulse frequency (the inverse of the pulse frequency is the pulse interval). The higher the frequency (the smaller the pulse interval) and the greater the energy, the faster the efficiency, but the greater the laser energy, the less safe it is.

[0003] Among them, the reference document 1 (CN 201911050109.5) provides a device and method for reducing the attenuation of a laser beam in a liquid medium, which includes at least two laser devices, which are suitable for generating at least two laser beams, one of the at least two laser beams is generated by a holmium laser, and the other of the at least two laser beams is generated by a thulium laser, wherein the laser system 20 is composed of a laser module 21 and a control component 22. The laser beam 23 emitted by the laser module 21 is configured to be transmitted to the optical waveguide 24 through a connector 25. The partially transparent mirror 26a is positioned along the optical path of the laser beam 23 and is configured to reflect at least a portion of the laser beam 23 into the photodetector module 27. A portion of the backscattered light from the targeted tissue enters the optical waveguide 24 and passes through the connector 25, which is configured to be partially targeted by the rotating mirror 26b and enters the module 29. The module 29 is configured to measure the distance between the top of the waveguide 24 and the targeted tissue. Modules 27 and 29 can also be controlled by programmable controller 22. The core is that the first pulse is large enough to form water vapor bubbles in the liquid medium at the transmission end of the optical fiber, and the second pulse is transmitted to the target tissue part through the water vapor bubbles, the purpose of which is to reduce the retreat of the tissue part. However, this does not solve the problem of reducing the energy carried by a single pulse under the premise of maintaining a certain total energy per unit time to ensure the safety of the operation.

[0025] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0026] This specific implementation provides a medical laser device that is compatible with single-pulse and double-pulse modes, which solves the technical problem in the prior art that the existing laser devices carry relatively large energy, resulting in a relatively high risk factor.

[0027] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0028] Reference Figure 1-Figure 4The present invention provides a medical laser device compatible with single pulse and double pulse modes, including a laser generating module, wherein the laser generating module includes a housing 1, a first laser emitter 2, a second laser emitter 3, a coupling module 4, a beam combining module 6, a reflection module 5, and a control module 7. The first laser emitter 2, the second laser emitter 3, the reflection module 5, and the beam combining module 6 are arranged in the housing 1, and the coupling module 4 is arranged on the housing 1 for receiving a first light beam generated by the first laser emitter 2 and a second light beam generated by the second laser emitter 3, wherein the emission port of the first laser emitter 2 is aligned with the receiving port of the coupling module 4, so that the first light beam emitted by the first laser emitter 2 directly reaches the coupling module 4 for transmission, the emission direction of the second laser emitter is parallel to that of the first laser emitter 2, and the second light beam of the second laser emitter 3 is reflected to the coupling module 4 via the reflection module 5 and the beam combining module 6, so as to facilitate the transmission of the second light beam, wherein the beam combining module 6 is arranged between the first laser emitter 2 and the coupling module 4, and can allow the light beam generated by the first laser generating module to pass through, and can select the time for the first light beam or the second light beam to pass through.

[0029] Among them, the control module 7 is electrically connected to the beam combining module 6, the first laser emitter 2, and the second laser emitter 3, so that the control module 7 controls the beam combining module 6 to control the time for the first light beam and the second light beam to pass through, and also controls the frequency of turning on the first laser emitter 2 and the second laser emitter 3. When the beam combining module 6 allows the first light beam to pass through, the first laser emitter 2 is turned on, and when the beam combining module 6 allows the second light beam to pass through, the second laser emitter 3 is turned on. Specifically, when people use it, since the beam combining module 6 is arranged between the first laser emitter 2 and the coupling module 4, the coupling module 4 can directly receive the first light beam generated by the first laser emitter 2, and the second laser emitter is transmitted to the coupling module 4 through the reflection module 5 and the reflection of the beam combining module 6, wherein the beam combining module 6 chooses whether to allow the first light beam to pass through or the second light beam to pass through at the same time, that is, the two cannot pass through at the same time, but within a period of time, the coupling module 4 receives the light beams frequently in sequence; in this way, the energy carried by each light beam can be reduced, and the energy generated within a certain period of time is the same. For example, the energy of a double pulse of 10Hz0.5J is equivalent to the existing power of 10Hz1.0J. The energy of each pulse is reduced, making the energy of a single pulse lower, the pulse interval smaller, the efficiency higher, and the safety improved.

[0030] In this embodiment, in order to form an equal energy pulse group, the energy of the first light beam emitted by the first laser emitter 2 is the same as the energy of the second light beam emitted by the second laser emitter, thus forming an equal energy pulse group.

[0031] In this embodiment, in order to facilitate the selection of the beam combining module 6, the beam combining module 6 includes a bracket 62, a motor 61, a mirror frame 63, and a first reflector 64. The motor 61 is installed on the bracket 62, the bracket 62 is installed in the shell 1, the first reflector 64 is installed on the mirror frame 63, and the mirror frame 63 is installed on the output shaft of the motor 61. The motor 61 drives the mirror frame 63 to rotate. With the output shaft of the motor 61 as the center, half of the space on the mirror frame 63 is set with the first reflector 64, and the other half is for the first light beam emitted by the first laser emitter 2 to pass through. When the first reflector 64 can receive the second light beam, the first reflector 64 reflects the second light beam to the coupling module 4. When the first reflector 64 cannot receive the second light beam, the first light beam passes through the beam combining module 6 and directly reaches the coupling module 4.

[0032] The control module 7 can adjust the rotation speed of the motor 61 to achieve switching between single pulse and double pulse.

[0033] In this embodiment, in order to protect the first reflector 64 , the beam combining module 6 further includes a cover plate 65 disposed on the movable plate 66 . The cover plate 65 is provided with a through hole for the light beams of the first laser emitter 2 and the second laser emitter 3 to pass through.

[0034] In this embodiment, in order to detect which light beam is passing through the beam combining module 6, a sensor 67 is provided on the beam combining module 6. The sensor 67 is electrically connected to the control module 7. The sensor 67 detects the position of the first reflector on the mirror frame to transmit a signal to the control module 7.

[0035] In this embodiment, the beam combining module 6 also includes a movable plate 66 and an adjusting component. The movable plate 66 is movably mounted on the bracket, the motor is mounted on the movable plate 66, and the adjusting component adjusts the position of the movable plate 66, wherein the adjusting component can be an adjusting screw, and the movable plate 66 and the bracket 62 are both provided with threaded holes, and the adjusting screw is simultaneously passed through the threaded holes on the movable plate 66 and the bracket 62, thereby facilitating the adjustment of the position of the movable plate 66 and the motor 61, so that the position of the through hole on the cover plate 65 is aligned with the emission port of the first laser emitter 2.

[0036] In this embodiment, the coupling module 4 includes a mounting shell, a first lens 41, a protective sheet 42, and an optical fiber connector 43. The mounting shell is mounted on the housing 1, and the first lens 41, the protective sheet 42, and the optical fiber connector 43 are sequentially mounted in the mounting shell. The first lens 41 is used to receive the first light beam and the second light beam, and the protective sheet 42 is used to protect the first lens 41 to prevent the optical fiber from damaging the first lens 41 when installing the optical fiber.

[0037] In this embodiment, the medical laser equipment compatible with single pulse and double pulse modes also includes a laser power module 8 and a frame 9. The laser power module 8 provides power to the laser generating module and the control module 7, and the control module 7, the laser power module 8, and the laser generating module are installed on the frame 9. When people move, they can directly move the frame 9 to achieve the movement of the medical laser equipment compatible with single pulse and double pulse modes.

[0038] In this embodiment, the medical laser equipment compatible with single pulse and double pulse modes also includes a cooling module 10, which is connected to the laser generating module. The control module 7 is electrically connected to the cooling module 10. Since the laser generating module continuously generates heat when working, in order to speed up the dissipation of heat, the cooling module 10 cools the excitation generator to extend the service life of the laser generating module.

[0039] The present application provides a medical laser device that is compatible with single-pulse and double-pulse modes. When in use, the sensor 67 first detects the state of the beam combining module 6 and transmits it to the control module 7. When the detection signal is the first beam, the control module 7 sends the discharge signal of the first beam to the laser power module 8, so that the first laser emitter 2 outputs a single-pulse laser beam; when the detection signal is the second beam, the control module 7 sends the discharge signal of the second beam to the laser power module 8, so that the second laser emitter 3 outputs a single-pulse laser beam. The discharge signal interval between the first beam and the second beam can be determined according to the working parameters of the control module 7, ranging from milliseconds to one second. When it is at the millisecond level, the time interval of the single-pulse laser beams generated by the first laser emitter 2 and the second laser emitter 3 is controlled at the millisecond level, so that the laser generating module generates two spatially distributed single-pulse laser beams that are combined into a double-pulse laser beam with a time interval of milliseconds. This reduces the energy carried by each beam and improves safety. At the same time, the total energy of the beam within a certain period of time is unchanged. When the interval between discharge signals from the first laser emitter 2 is relatively large, the two spatially distributed single-pulse laser beams each become a single-pulse laser beam.

[0040] Specifically, the operating parameters are input into the control module 7: dual pulse mode (the default is 2ms or other ms level, or 1-10ms adjustable), frequency 10Hz, laser energy 1J, the control module 7 sends a frequency control signal to the motor 61, the motor works according to the dual pulse mode and 10Hz operating parameters, the motor drives the first reflector 64 to rotate, the sensor 67 first detects the position signal of the first reflector (that is, the position of the through hole on the cover plate 65 does not correspond to the first reflector 64), and provides the position signal of the first reflector to the control module 7, after receiving the signal, the control module 7 sends an electrical signal to the laser power module 8, the laser power module 8 discharges the first laser emitter according to the operating parameters of 5Hz / 0.5J, and generates a 5Hz / 0.5J single pulse laser beam. After 2ms, the motor of the beam combining module 6 turns to align the first reflector with the position of the through hole, and the sensor provides the detected signal to the control module 7. After receiving the signal, the control module 7 sends a discharge signal to the laser power module 8. The laser power module 8 discharges the second laser emitter 3 according to the working parameters of 5Hz / 0.5J to generate a 5Hz / 0.5J single-pulse laser beam. As a result, the two laser generating modules generate two spatially distributed 5Hz / 0.5J single-pulse laser beams, which are synthesized into a 10Hz / 1J double-pulse laser beam with a time interval of 2 milliseconds. At this time, the time interval between the two single pulses of path A and path B is 2ms, forming a double pulse, and the time interval between the double pulses is 100ms (10Hz). The synthesized laser beam passes through the lens and protective sheet 42 of the coupling module 4 respectively, and is coupled into the medical optical fiber through the optical fiber interface.

[0041] When single pulse is selected, the interval between the two single pulse laser beams generated by the first laser emitter 2 and the second laser emitter 3 is determined by the frequency input by the control module 7 .

[0042] For example, input working parameters: single pulse mode, frequency 10Hz, laser energy 1J. The control module 7 sends a frequency control signal to the motor of the beam combining module 6, so that the motor works according to the single pulse mode and 10Hz working parameters. The motor drives the beam combining lens to rotate. The sensor of the beam combining module 6 first detects the position signal of the first reflector (that is, the position of the through hole on the cover plate 65 does not correspond to the first reflector 64), and provides the position signal to the control module 7. After receiving the signal, the control module 7 sends a discharge signal to the laser power module 8. The laser power module 8 discharges the first laser emitter according to the working parameter of 5Hz / 1J to generate a 5Hz / 1J single pulse laser beam. After 100ms, the motor of the beam combining module 6 turns to align the first refractor with the position of the through hole. The sensor provides the position signal to the control module 7. After receiving the signal, the control module 7 sends a discharge signal to the laser power module 8. The laser power module 8 discharges the second laser emitter according to the working parameter of 5Hz / 1J to generate a 5Hz / 1J single pulse laser beam. Thus, the two laser emitters generate two spatially distributed 5Hz / 1J single pulse laser beams, which are synthesized into a 10Hz / 1J double pulse laser beam with a time interval of 100 milliseconds. At this time, the time interval between the two single pulses of the first beam and the second beam is 100ms. The synthesized laser beam passes through the lens and the protective sheet 42 of the coupling module 4 respectively, and is coupled into the medical optical fiber through the optical fiber interface.
