Description

Technical Field

[0001] The invention relates to the technical field of laser devices, and in particular provides an ophthalmic laser device which can be adjusted quickly. Background Art

[0002] Ophthalmic laser surgery uses a laser device to generate laser light and acts on the eye through a controllable laser to treat the eye. Laser treatment of the eye requires high precision, and the laser focus position needs to be accurately matched to the treatment position before treatment.

[0003] Due to the large size and weight of laser equipment, the laser equipment will have low precision due to large inertia when moving, so the patient's position is usually moved by moving the operating table to adjust the focus position of the laser on the eye. However, frequent movement of the operating table will cause the position of doctors and nurses relative to the operating table to change, resulting in inconvenience in operation, and will also cause patients to be nervous, affecting treatment. Summary of the invention

[0004] The present invention provides an ophthalmic laser device which can be adjusted quickly, and is used to solve the problem that laser surgery requires frequent movement of an operating table, which causes inconvenience to doctors and nursing staff, and also causes tension in patients, thus affecting treatment.

[0005] The technical solution of the present invention is as follows:

[0006] A rapidly adjustable ophthalmic laser device comprising a laser source, a guide assembly and a focusing lens;

[0007] The laser source is used to generate a laser beam;

[0008] The guide assembly is used to reflect the laser beam to the focusing mirror and adjust the position of the focusing mirror;

[0009] The guide assembly includes a base, a first slide, a second slide, a lifting platform and a CCD visual detection component. A first guide rail is arranged between the first slide and the base. The first slide is slidably connected to the first guide rail. The length direction of the first guide rail is parallel to the direction of the laser beam generated by the laser source. The first slide is provided with a second guide rail. The second slide is slidably connected to the second guide rail. The second guide rail is perpendicular to the first guide rail. The first guide rail and the second guide rail are both parallel to the horizontal plane. The first slide is provided with a first reflector, and the second slide is provided with a second reflector. The first reflector is used to reflect the laser beam generated by the laser source to the second reflector. The second slide is provided with a vertical guide rail and a third reflector. The lifting platform is slidably connected to the vertical guide rail. The focusing mirror is connected to the lifting platform. The axis of the focusing mirror is parallel to the vertical guide rail. The second reflector is used to reflect the laser beam to the third reflector. The third reflector is used to reflect the laser beam to the focusing mirror. The lifting platform moves in the vertical direction to adjust the focal position of the focusing mirror in the vertical direction. The CCD visual detection component is used to display an image of the corresponding area of ​​the focusing mirror.

[0010] In this solution, the laser light generated by the laser source can be reflected to the focusing mirror by the first reflecting mirror, the second reflecting mirror and the third reflecting mirror, and the position of the focusing mirror can be adjusted by the first slide, the second slide and the lifting platform, and during the adjustment process, the first reflecting mirror, the second reflecting mirror and the third reflecting mirror will always reflect the laser beam to the focusing mirror. Therefore, the focusing mirror can be moved by the first slide, the second slide and the third slide without moving the laser source, which greatly reduces the volume and weight of the parts that need to be moved, making the movement of the focusing mirror light and accurate. While ensuring that the movement accuracy of the laser beam is sufficient, the position of the laser beam relative to the eye can be changed by moving the focusing mirror, so there is no need to move the operating table, which solves the problem that the operation of doctors and nurses will not change due to the moving operating table and the patient will be nervous and affect the treatment.

[0011] In order to solve the problem of unclear eye images obtained by the CCD visual detection component, the ophthalmic laser device also includes a light source, which is connected to the second slide, and the second slide is provided with a fourth reflector, which is used to reflect the illumination light beam generated by the light source to the focusing mirror.

[0012] In this solution, the illumination light beam provided by the light source is irradiated onto the focusing mirror, and the reflected light reflected by the focusing mirror is transmitted to the CCD visual detection component, which is used to form an eye image. In the presence of an illumination light beam, the eye image formed by the CCD visual detection component is clearer and more accurate, making it easier for doctors and nurses to observe.

[0013] Preferably, the illumination light beam reflected by the fourth reflector is coaxial with the laser beam reflected by the third reflector, and the illumination light beam passes through the third reflector and coincides with the laser beam.

[0014] Preferably, the third reflector is a broadband beam splitter plate.

[0015] In this solution, the third reflector adopts a broadband beam splitter plate, so that the third reflector can reflect the laser beam and allow the illumination beam to pass through, which is convenient for the installation of the light source.

[0016] In order to reduce the volume of the second slide, a fifth reflector is arranged between the fourth reflector and the light source. The fifth reflector is a dichroic mirror. The reflected light of the focusing mirror passes through the third reflector and the fourth reflector, and is reflected from the fifth reflector to the CCD visual detection component. The third reflector, the fourth reflector and the fifth reflector are all broadband spectroscopic plates.

[0017] In this solution, the reflected light from the focusing mirror is reflected to the CCD visual detection component through the fifth reflector, which can change the transmission path of the reflected light, so that the installation position of the CCD visual detection component can be adjusted, and the CCD visual detection component does not need to be installed on the upper side of the focusing mirror, which can reduce the vertical height of the second slide, thereby achieving the effect of reducing the volume and facilitating the operation of doctors and nurses. The fourth reflector divides the reflected light into two parts, one part is transmitted to the microscope to facilitate the observation of the position of the laser beam in the patient's eye; the other part is transmitted to the CCD visual detection component.

[0018] Preferably, a cemented lens is further provided between the fifth reflector and the CCD visual detection component, and the reflected light reflected by the fifth reflector passes through the cemented lens and then is transmitted to the CCD visual detection component.

[0019] In this solution, the cemented lens can further improve the image quality generated by the CCD visual detection component, making it easier for doctors and nurses to observe the patient's eye condition.

[0020] Preferably, the ophthalmic laser device also includes a microscope and a sixth reflector, the reflected light of the focusing mirror is reflected to the microscope through the sixth reflector, the microscope and the sixth reflector are respectively arranged on the second slide, and the microscope is used to observe the horizontal position of the focus of the focusing mirror.

[0021] In this scheme, the focusing mirror is used to focus the laser beam on the patient's eye, so that the energy of the laser beam is concentrated in one place, thereby treating the patient's eye. Before the focus of the focusing mirror coincides with the patient's eye, a circular light spot will be formed on the patient's eye. A microscope is set to observe the relative position of the light spot and the eye. The smaller the light spot, the closer the distance between the focus and the patient, and the more concentrated the energy of the beam. Conversely, the larger the light spot, the larger the distance between the focus position and the patient's eye, and the more dispersed the energy of the beam. Laser surgery requires the energy of the laser beam to be concentrated to treat the patient's position. The reflected light of the focusing mirror is reflected to the microscope, and the field of view observed by the microscope is affected by the focus position. When the focus is close to the patient's eye, the range of the patient's eye observed by the microscope will be reduced. Before adjusting the focus position, the light spot position is observed through a microscope. At this time, the distance between the focus and the patient's eye is large, and the range of the patient's eye that the microscope can observe is large. The focus can be moved to the patient's position first, so that the midpoint of the light spot coincides with the patient's position, and then the focus is performed through the lifting platform. Because the midpoint of the light spot coincides with the patient's position, the focal point after focusing will coincide with the patient's position, and there is no need to adjust the focal position after focusing, thereby improving the efficiency of focusing on the patient's position.

[0022] Preferably, the sixth reflector is a dichroic mirror.

[0023] In this solution, the sixth reflector adopts a dichroic mirror, which can divide the reflected light of the focusing mirror into two parts. One part is transmitted to the microscope, and the other part passes through the sixth reflector and is transmitted to the CCD visual detection component, so that doctors and nurses can observe the position of the light spot formed by the laser beam in the patient's eye through the microscope, and at the same time observe the patient's eye condition through the CCD visual detection component.

[0024] Preferably, a driving mechanism is provided between the first slide and the base, and the driving mechanism is used to drive the first slide to move;

[0025] A driving mechanism is provided between the second slide and the first slide, and the driving mechanism is used to drive the second slide to move;

[0026] A driving mechanism is arranged between the lifting platform and the second sliding platform, and the driving mechanism is used for driving the lifting platform to move.

[0027] In this solution, the positions of the first slide table, the second slide table and the lifting table are adjusted by the driving mechanism, so that the adjustment efficiency can be improved.

[0028] Preferably, a spring is arranged between the lifting platform and the second slide, the top end of the spring is connected to the second slide, and the bottom end of the spring is connected to the lifting platform, the spring is in a balanced state, and the lifting platform is located at the top of the third guide rail.

[0029] In this solution, the initial position of the lifting platform is maintained at the top of the third guide rail by a spring, so that the height of the focusing mirror is maintained at the highest position, and the focal height of the focusing mirror is higher than the patient's eyes. The laser beam forms a larger light spot in the patient's eyes, and the position of the light spot can be quickly adjusted so that the center of the light spot coincides with the affected part of the patient's eyes, thereby improving the adjustment efficiency.

[0030] Beneficial effects of the present invention:

[0031] The present invention arranges the focusing mirror on the guide component, and the position of the focusing mirror can be adjusted by the guide component. When adjusting the position of the focusing mirror, there is no need to adjust the position of the laser source. The volume and weight of the focusing mirror are much smaller than the volume and weight of the laser source. The position of the laser relative to the patient's eyes can be adjusted by adjusting the position of the focusing mirror. There is no need to adjust the position of the operating table, which will not cause the position of the doctor and the nurse relative to the operating table to change, and will not cause inconvenience to the doctor and the nurse's operation. At the same time, it also solves the problem of patient tension caused by the movement of the operating table. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through specific implementation methods of the embodiments of the present invention.

[0039] Embodiment 1:

[0040] like Figure 1 and Figure 2 As shown, the first embodiment provides a rapidly adjustable ophthalmic laser device, including a laser source 1, a guide component 2 and a focusing mirror 3, wherein the laser source 1 is used to generate a laser beam, the laser beam is irradiated onto the guide component 2, the focusing mirror 3 is arranged on the guide component 2, the guide component 2 can guide the direction of the laser beam so that the laser beam can be irradiated onto the focusing mirror 3, and at the same time, the position of the focusing mirror 3 can be adjusted by the guide component 2, and the laser beam can be continuously transmitted to the focusing mirror 3 during the adjustment process.

[0041] like Figure 3 As shown, the guide assembly 2 includes a base 201, a first slide 202, a second slide 212, a lifting platform 213 and a CCD visual detection component 209. The first slide 202 is slidably arranged on the base 201. The base 201 is provided with a first guide rail. The first slide 202 is slidably connected to the first guide rail. The sliding direction of the first slide 202 is parallel to the direction and horizontal plane of the laser beam generated by the laser source 1. The first slide 202 is provided with a first anti-color mirror, and the first reflector 203 is used to reflect the laser beam. Because the sliding direction of the first slide 202 is parallel to the laser beam, when the first slide 202 slides, the laser beam is always irradiated on the first reflector 203, so that the first reflector 203 can continuously reflect the laser beam.

[0042] A second guide rail is provided on the first slide 202, and the second slide 212 is slidably connected to the second guide rail. The sliding direction of the second slide 212 is parallel to the horizontal plane, and the sliding direction of the second slide 212 is perpendicular to the laser beam. A second reflector 204 is provided on the second slide 212, and the first reflector 203 reflects the laser beam to the second reflector 204. The axis of the first reflector 203 is tilted relative to the laser beam generated by the laser source 1, and the tilt angle is 45°. The axis of the first reflector 203 is parallel to the horizontal plane, and the tilt angle is an angle in the horizontal plane. Because the angle between the axis of the first reflector 203 and the laser beam generated by the laser source 1 is 45°, the laser beam reflected by the first reflector 203 is parallel to the second guide rail, and when the second slide 212 moves, the laser beam reflected by the first reflector 203 can always irradiate the second reflector 204.

[0043] The second slide 212 is also provided with a third reflector 215 and a third guide rail, the third guide rail is vertically arranged, the lifting platform 213 is slidably connected to the third guide rail, the focusing mirror 3 is connected to the lifting platform 213, and the focusing mirror 3 is located at the lower side of the third reflector 215, the second reflector 204 reflects the laser beam to the third reflector 215, and the third reflector 215 reflects the laser beam to the focusing mirror 3. The axis of the focusing mirror 3 is vertical, and the axis of the third reflector 215 is inclined relative to the vertical plane, and the angle between the axis of the third reflector 215 and the vertical plane is 45°.

[0044] When the lifting platform 213 moves up and down, the distance between the focusing mirror 3 and the third reflector 215 changes. When the patient lies on the operating table, the height of the focusing mirror 3 can be changed to change the focal position of the focusing mirror 3. When the focus coincides with the patient's eyes, the energy of the focusing mirror 3 is most concentrated in the patient's eyes. When the focus of the focusing mirror 3 is far away from the patient's eyes, an obvious light spot will be formed in the patient's eyes. The third reflector 215 is a dichroic mirror. The laser beam is focused on the patient's eyes through the focusing mirror 3. The focusing mirror 3 will form a reflected light. The reflected light will pass through the third reflector 215 and be transmitted to the CCD visual detection component 209, so that the CCD visual detection component 209 can obtain the patient's eye image through the reflected light. The image obtained is related to the focusing range of the focusing mirror 3. When the focus of the focusing mirror 3 coincides with the patient's eyes, the image magnification ratio is the largest.

[0045] The focusing lens 3 may be a white light confocal probe.

[0046] The second slide 212 is equipped with a light source 207 and a fourth reflector 211. The light source 207 may be an LED lamp. The axis of the fourth reflector 211 is tilted relative to the horizontal plane. The light source 207 is used to generate an illumination beam, which is irradiated to the fourth reflector 211 and then reflected from the fourth reflector 211 to the third reflector 215. When the light source 207 is provided, the image obtained by the CCD visual detection component 209 is clearer, which is convenient for doctors and nurses to observe the patient's eye condition.

[0047] The third reflector 215 can be a broadband beam splitter plate, and the third reflector 215 can split light according to different wavelengths. The wavelength of the laser beam is within the reflection wavelength range of the third reflector 215, so the laser beam will be reflected; while the illumination beam generated by the light source 207 may continue to propagate through the third reflector 215.

[0048] The illumination beam reflected by the fourth reflector 211 is coaxial with the focusing mirror 3. The focusing mirror 3 can only move up and down along the direction of the third guide rail. During the movement of the focusing mirror 3, the illumination beam will not deviate from the focusing mirror 3, ensuring that the focusing mirror 3 always obtains the illumination effect.

[0049] A microscope 206 and a fifth reflector 205 are also installed on the second slide 212. The fifth reflector 205 is used to reflect the reflected light of the focusing mirror 3 to the microscope 206. The function of the microscope 206 is to observe the relative position relationship between the laser beam and the patient's eye disease. After the focusing mirror 3 focuses the laser beam, the focused laser beam will irradiate the patient's eye. At this time, the microscope 206 can observe the light spot formed by the laser beam on the patient's eye. After observing the position of the light spot, the first slide 202 and the second slide 212 can be moved to change the position of the light spot, thereby moving the center of the light spot to the patient's eye disease. After the center of the light spot moves to the patient's eye disease, the height of the focusing mirror 3 is changed by the lifting platform 213 so that the focus of the focusing mirror 3 coincides with the patient's eye, thereby performing surgery on the patient's eye. This method of first adjusting the light spot position and then focusing the laser beam can improve the adjustment efficiency of the laser beam and shorten the operation time.

[0050] The fifth reflector 205 can adopt a dichroic beam splitter, which divides the reflected light from the focusing mirror 3 into two parts. The two parts of the reflected light have different wavelengths. One part is transmitted to the microscope 206 so that the microscope 206 can observe the position of the light spot, and the other part is transmitted to the CCD visual detection component 209. The CCD visual detection component 209 obtains the patient's eye image through this part of the reflected light.

[0051] A sixth reflector 208 can also be set on the second slide 212. The sixth reflector 208 is set between the fourth reflector 211 and the light source 207. The reflected light of the condenser passes through the third reflector 215 and then irradiates the fifth reflector 205. After passing through the fifth reflector 205, part of the reflected light is reflected by the fourth reflector 211 to the sixth reflector 208, and then reflected from the sixth reflector 208 to the CCD visual detection component 209. The CCD visual detection component 209 obtains an eye image through the reflected light reflected by the sixth reflector 208.

[0052] The sixth reflector 208 can be a broadband spectroscopic plate, and the broadband spectroscopic plate is coated with a spectroscopic film on one side and an anti-reflection film on the other side. The spectroscopic film can divide the incident light into reflected light and transmitted light, and the anti-reflection film is used to reduce the loss of reflected light on the other side and improve the efficiency of transmitted light. The design of the broadband spectroscopic plate can adjust the ratio of reflected light to transmitted light as needed. Common ratios include: 10% transmission and 90% reflection, 20% transmission and 80% reflection, 30% transmission and 70% reflection, 40% transmission and 60% reflection, 50% transmission and 50% reflection (half reflection and half transmission), 60% transmission and 40% reflection, 70% transmission and 30% reflection, 80% transmission and 20% reflection, etc. In order to achieve the effect of light transmission from one side and reflection from the other side, a broadband spectroscopic plate with a higher reflection ratio can be selected, such as 10% transmission and 90% reflection or 20% transmission and 80% reflection.

[0053] A cemented lens 210 is also provided on the second slide 212 . The reflected light is transmitted from the sixth reflector 208 to the cemented lens 210 , and then transmitted from the cemented lens 210 to the CCD visual detection component 209 .

[0054] A driving mechanism is respectively arranged on one side of the first guide rail, the second guide rail and the third guide rail, and the driving mechanism can be replaced by a linear motor.

[0055] The driving mechanism can adopt another embodiment, the driving mechanism includes a screw nut assembly and a driving motor, the driving motor is used to drive the screw in the screw nut assembly to rotate the screw, and the rotation of the screw will cause the nut to move along the axis of the screw, so as to move the first slide 202, the second slide 212 and the lifting platform 213. For example, a driving mechanism is provided on one side of the first guide rail, wherein the screw in the screw nut assembly is rotatably connected to the base 201, the nut in the screw nut assembly is connected to the first slide 202, the driving motor is connected to the base 201, and the output shaft of the driving motor is connected to the screw. When the driving motor drives the screw to rotate, the nut moves along the axis of the screw, and the movement of the nut will carry the first slide 202 along the axis of the screw, thereby achieving the effect of driving the first slide 202 to move. Similarly, the second slide 212 and the lifting platform 213 can be driven to move by the driving mechanism.

[0056] If the driving mechanism adopts a linear motor, a spring 214 is provided between the lifting platform 213 and the second slide 212. The top end of the spring 214 is connected to the second slide 212, and the bottom end of the spring 214 is connected to the lifting platform 213. When the driving mechanism stops working and the spring 214 is in a force balance state, the lifting platform 213 is located at the top end of the third guide rail. Therefore, the linear motor is used to drive the lifting platform 213 to move downward. The advantage of this setting method is that the height of the focusing mirror 3 can be placed at the highest position. Before adjusting the position of the laser beam, the spot size formed by the laser beam in the patient's eye is large, and the center of the spot can be adjusted to the affected part of the patient's eye more efficiently.

[0057] The driving motor or linear motor is equipped with a controller, and the doctor or nurse controls the driving motor or linear motor through the controller, thereby moving the first slide 202, the second slide 212 and the lifting platform 213.

[0058] The controller may be a PLC.
