Description

Technical Field

[0001] The embodiments of the present application relate to the field of medical equipment, and in particular to a laser emitting device. Background Art

[0002] During corneal cross-linking surgery using therapeutic laser, a laser emitting device is usually required to position the therapeutic laser relative to the pupil.

[0003] The current laser emitting device is used to emit multiple lasers with the same intersection. The laser emitting device is usually fixedly connected to a structure for emitting therapeutic lasers. The therapeutic laser emitted by the structure passes through the laser intersection of the laser emitting device, and the distance between the position where the structure emits the therapeutic laser and the laser intersection of the laser emitting device is a preset distance. During the corneal cross-linking surgery, the position of the laser emitting device can be adjusted first so that the laser intersection of the laser emitting device is located on the pupil of the eye to be treated. At this time, the structure for emitting therapeutic lasers will adjust its position synchronously with the laser emitting device, and then the structure can be turned on to emit the therapeutic laser, and the therapeutic laser will treat the pupil. At this time, the therapeutic laser will treat the pupil when the distance between the emission point and the pupil is the preset distance.

[0004] However, when producing laser emitting devices, due to processing and assembly errors, there is a situation where multiple lasers emitted by the produced laser emitting devices do not have the same intersection, so that the yield rate of the produced laser emitting devices is low, and rework or additional production is required, resulting in low production efficiency of the laser emitting devices.

[0005] In view of this, an embodiment of the present application provides a laser emitting device to at least partially solve the above-mentioned problem.

[0006] According to a first aspect of an embodiment of the present application, a laser emitting device is provided, which includes a plurality of laser emitting structures, wherein the lasers emitted by the plurality of laser emitting structures have a same intersection, and the laser emitting structures include a support seat, a laser, and an adjustment component; the support seats included in the plurality of laser emitting structures are connected to each other, and a cavity is provided in the support seat; the laser is located in the cavity, and the laser includes a first end and a second end, and the laser emitted by the laser is emitted from the first end to the outside of the laser, and the second end is an end of the laser away from the first end, and a first light-transmitting hole is provided in the support seat at a position opposite to the first end; the adjustment component is used to adjust the position of the first end or the second end in the cavity, so as to adjust the position of the intersection of the lasers emitted by the plurality of laser emitting structures relative to the support seat.

[0008] In a second possible implementation, in combination with the above-mentioned first possible implementation, each of the laser emitting structures includes two adjustment components, and the adjustment directions of the two adjustment components in the same laser emitting structure are perpendicular to each other, and the adjustment direction of the adjustment component is from the top piece in the adjustment component to the elastic piece in the adjustment component.

[0009] In a third possible implementation manner, in combination with the first possible implementation manner or the second possible implementation manner, the adjustment components included in the same laser emitting structure are arranged on the same plane or on different planes.

[0010] In a fourth possible implementation, in combination with the first aspect above, a ball seat is externally connected to the first end or the second end, the outer surface of the ball seat is a spherical arc surface, the outer surface of the ball seat and the inner surface of the support seat formed by the cavity fit each other, and if the ball seat is sleeved on the outside of the first end, a second light-transmitting hole is opened at a position opposite to the end face of the ball seat and the first end.

[0011] In a fifth possible implementation, in combination with the first aspect, a receiving groove is provided on the inner surface of the support seat formed by the cavity, and the end of the elastic member away from the laser is located in the receiving groove.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0024] The laser emitting device provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0025] Figure 1 is a schematic diagram of a laser emitting device provided in an embodiment of the present application, Figure 2 is a cross-sectional view of a laser emitting device provided in an embodiment of the present application. Figure 1 and Figure 2 As shown, the laser emitting device provided in the embodiment of the present application includes a plurality of laser emitting structures 1, the lasers emitted by the plurality of laser emitting structures 1 have a same intersection, and the laser emitting structure 1 includes a support seat 11, a laser 12 and an adjustment component 13;

[0026] The support seats 11 included in the multiple laser emitting structures 1 are connected to each other, and a cavity 111 is provided in the support seat 11;

[0027] The laser 12 is located in the cavity 111. The laser 12 includes a first end 121 and a second end 122. The laser emitted by the laser 12 is emitted from the first end 121 to the outside of the laser 12. The second end 122 is the end of the laser 12 away from the first end 121. A first light-transmitting hole 112 is provided in the support base 11 at a position opposite to the first end 121.

[0028] The adjustment component 13 is used to adjust the position of the first end 121 or the second end 122 in the cavity 111 to adjust the position of the intersection of the lasers emitted by the plurality of laser emitting structures 1 relative to the support base 11 .

[0029] It should be noted that if the adjustment component 13 is used to adjust the position of the first end 121 in the cavity 111, then in the process of adjusting the position of the first end 121 in the cavity 111 by the adjustment component 13, the laser 12 will rotate with the second end 122 as the rotation point; if the adjustment component 13 is used to adjust the position of the second end 122 in the cavity 111, then in the process of adjusting the position of the second end 122 in the cavity 111 by the adjustment component 13, the laser 12 will rotate with the first end 121 as the rotation point; the drawings provided in the embodiments of the present application are examples of the adjustment component 13 being used to adjust the position of the second end 122 in the cavity 111.

[0030] In the embodiment of the present application, the laser emitting device includes a plurality of laser emitting structures 1 for emitting lasers, the laser emitting structure 1 includes a support seat 11, a laser 12 and an adjustment component 13, and the adjustment component 13 is used to adjust the position of the first end 121 or the second end 122 in the cavity 111 of the support seat 11, so as to adjust the position of the intersection of the lasers emitted by the plurality of laser emitting structures 1 relative to the support seat 11. After the laser emitting device is produced, the position of the second end 122 in the cavity 111 can be adjusted by the adjustment component 13, at which time the laser 12 will rotate with the first end 121 as the rotation point, or the position of the first end 121 in the cavity 111 can be adjusted by the adjustment component 13, at which time the laser 12 will rotate with the second end 122 as the rotation point, so that the direction of the laser emitted by the laser emitting structure 1 changes, until the lasers emitted by the plurality of laser emitting structures 1 included in the laser emitting device have a same laser intersection, and the position of the laser intersection relative to the support seat 11 meets the expected design. It can be seen that after the laser emitting device is produced, the directions of the multiple lasers emitted by the laser emitting device can be adjusted by adjusting the component 13 until the multiple lasers have a same intersection, and the position of the intersection relative to the support seat 11 meets the expected design, so that there is no need to strictly limit the multiple lasers emitted by the completed laser emitting device to directly have the same intersection, so that the tolerance rate for processing and assembly errors is higher when producing the laser emitting device, the yield rate of the produced laser emitting devices is improved, the possibility of rework or supplementary production is reduced, and the production efficiency of the laser emitting device is improved.

[0031] In addition, the application scenarios of the laser emitting device are not limited in the embodiments of the present application. Specifically, Figure 3 is a schematic diagram of an application scenario of a laser emitting device provided in an embodiment of the present application, such as Figure 3As shown, the laser emitting device can be used in the treatment head of the corneal cross-linking device for performing corneal cross-linking surgery on the eye. The treatment head can also include a treatment laser emitting component 2, which is fixedly connected to the support seat 11 in the laser emitting device. The distance between the laser intersection of the laser emitting device and the treatment laser emission point of the treatment laser emitting component 2 is a preset distance. During the corneal cross-linking surgery on the eye, the operator can first turn on the laser emitting device to enable the multiple laser emitting structures 1 included in the laser emitting device to emit lasers. At this time, the lasers emitted by the multiple laser emitting structures 1 have and only have one same intersection. Then the operator can adjust the position of the treatment head until the laser intersection of the laser emitting device is located on the pupil of the eye to be treated. At this time, the laser emitting device can be turned off to stop the laser emitting device from emitting lasers, and the treatment laser emitting component 2 can be turned on to enable the treatment laser emitting component 2 to emit treatment lasers to the pupil of the eye to be treated, and the treatment laser emission of the treatment laser emitting component 2 can be made to be at the above-mentioned preset distance. At this time, the treatment laser begins to treat the eye to be treated.

[0032] like Figure 2 As shown, the support seats 11 in the multiple laser emitting structures 1 included in the laser emitting device can be integrally connected or fixedly connected to each other, the laser emitted by the laser emitting structure 1 is a non-therapeutic laser, and the cross-section of the laser emitted by the laser emitting structure 1 can be circular or cross-shaped, etc.; for each laser emitting structure 1, the adjustment component 13 it includes can be one or more.

[0033] In order to make the laser emitting device as simple as possible and save materials, Figure 2 As shown, the laser emitting device may include two laser emitting structures 1. Figure 2 As shown, the laser emitting device includes two laser emitting structures 1, the dotted line a is the path of the laser emitted by one laser emitting structure 1, the dotted line b is the path of the laser emitted by the other laser emitting structure 1, and the dotted line a and the dotted line b are located on the same plane and have an intersection.

[0034] In one possible implementation, Figure 2 As shown, the adjustment assembly 13 includes an elastic member 131 and a top member 132;

[0035] The laser 12 is located between the elastic member 131 and the top member 132;

[0036] The elastic member 131 is located in the cavity 111, one end of the elastic member 131 is connected to the support seat 11, the other end of the elastic member 131 abuts against the side of the laser 12, and the elastic member 131 is in a compressed state;

[0037] The top piece 132 is connected to the support seat 11, and one end of the top piece 132 abuts against the side surface of the laser 12;

[0038] When the top member 132 moves toward the direction close to the elastic member 131 , the top member 132 drives the first end 121 or the second end 122 of the laser 12 to move in the cavity 111 ;

[0039] When the top member 132 moves in a direction away from the elastic member 131 , the elastic member 131 drives the first end 121 or the second end 122 of the laser 12 to move in the cavity 111 .

[0040] It should be noted that if the adjustment component 13 is used to adjust the position of the first end 121 in the cavity 111, when the top piece 132 moves in a direction close to the elastic piece 131, the top piece 132 drives the first end 121 of the laser 12 to move in the cavity 111, and when the top piece 132 moves in a direction away from the elastic piece 131, the elastic piece 131 drives the first end 121 of the laser 12 to move in the cavity 111; if the adjustment component 13 is used to adjust the position of the second end 122 in the cavity 111, when the top piece 132 moves in a direction close to the elastic piece 131, the top piece 132 drives the second end 122 of the laser 12 to move in the cavity 111, and the top piece 132 moves in a direction away from the elastic piece 131. 32 moves in a direction away from the elastic member 131, the elastic member 131 drives the second end 122 of the laser 12 to move in the cavity 111; based on the drawings provided in the embodiments of the present application, the adjustment component 13 is used to adjust the position of the second end 122 in the cavity 111. For the laser emitting device exemplified in the drawings provided in the embodiments of the present application, when the top member 132 moves in a direction close to the elastic member 131, the top member 132 drives the second end 122 of the laser 12 to move in the cavity 111; when the top member 132 moves in a direction away from the elastic member 131, the elastic member 131 drives the second end 122 of the laser 12 to move in the cavity 111.

[0041] In the embodiment of the present application, the laser 12 is abutted between the elastic member 131 and the top member 132, the top member 132 is connected to the support seat 11, and when the top member 132 moves in the direction close to the elastic member 131, the top member 132 drives the second end 122 of the laser 12 to move in the cavity 111, and when the top member 132 moves in the direction away from the elastic member 131, the elastic member 131 drives the second end 122 of the laser 12 to move in the cavity 111. Since the top member 132 changes position relative to the support seat 11 in the direction close to or away from the elastic member 131, the first end 121 or the second end 122 of the laser 12 can be driven to move in the cavity 111, that is, the direction of the laser emitted by the laser 12 can be adjusted, so that the operation of adjusting the direction of the laser emitted by the laser emitting structure 1 can be made more convenient. When the top member 132 moves toward the elastic member 131, it moves along the straight line direction from the top member 132 to the elastic member 131. When the top member 132 moves away from the elastic member 131, it moves along the straight line direction from the elastic member 131 to the top member 132. Figure 2 As shown, the top member 132 moves along the direction of the dotted line c, toward or away from the elastic member 131.

[0042] The side surface of the laser 12 is a side surface of the outer surface of the laser 12 that is used to connect the end surface of the first end 121 and the end surface of the second end 122 .

[0043] The elastic member 131 may be a spring, a spring sheet or a rubber block, etc. The elastic member 131 is in a compressed state at least in a straight line direction from the elastic member 131 to the top member 132 .

[0044] The top piece 132 is a slider or a bolt, etc.; if the top piece 132 is a slider, the slider is slidably connected to the support seat 11 along the axial direction of the top piece 132, and the support seat 11 or the slider is provided with a locking piece that can relatively fix the slider and the fixed seat when the slider is slid to any position relative to the support seat 11.

[0045] In one possible implementation, Figure 1 and Figure 2 As shown, each laser emitting structure 1 includes two adjustment components 13, and the adjustment directions of the two adjustment components 13 in the same laser emitting structure 1 are perpendicular to each other. The adjustment direction of the adjustment component 13 is from the top component 132 in the adjustment component 13 to the elastic component 131 in the adjustment component.

[0046] In the embodiment of the present application, two adjustment components 13 are provided in the same laser emission structure 1, and the adjustment directions of the two adjustment components 13 are perpendicular to each other. Since the top pieces 132 in the two adjustment components 13 in the same laser emission structure 1 can move the first end 121 or the second end 122 of the laser 12 to any position on a certain arc spherical surface, the adjustment of the laser emission direction of the laser emission structure 1 can be more flexible.

[0047] In one possible implementation, Figure 1 and Figure 2 As shown, the adjustment component 13 included in the same laser emitting structure 1 is arranged on the same plane or not on the same plane. If it is arranged on the same plane, when the position of the second end 122 of the laser 12 is adjusted by different top pieces 132 included in the same laser emitting structure 1, the different top pieces 132 move similar distances relative to the support seat 11, and the distance moved by the first end 121 or the second end 122 of the laser 12 in the cavity 111 is also similar. Therefore, it is easier for the operator to grasp the adjustment rules when adjusting the laser emission direction of the laser emitting structure 1, thereby improving the efficiency of adjusting the laser emission direction of the laser emitting structure 1.

[0048] In one possible implementation, Figure 2 As shown, a ball seat 123 is connected to the outer surface of the first end 121 or the second end 122, and the outer surface of the ball seat 123 is a spherical arc surface. The outer surface of the ball seat 123 and the inner surface of the support seat 11 formed by the cavity 111 fit each other. If the ball seat 123 is sleeved on the outside of the first end 121, a second light-transmitting hole 1231 is opened at a position opposite to the end surface of the ball seat 123 and the first end 121.

[0049] It should be noted that if the adjustment component 13 is used to adjust the position of the first end 121 in the cavity 111, the ball seat 123 is sleeved on the outside of the second end 122; if the adjustment component 13 is used to adjust the position of the second end 122 in the cavity 111, the ball seat 123 is sleeved on the outside of the first end 121; the drawings provided based on the embodiments of the present application illustrate that the adjustment component 13 is used to adjust the position of the second end 122 in the cavity 111, and the drawings provided in the embodiments of the present application illustrate that the ball seat 123 is sleeved on the outside of the first end 121.

[0050] In the embodiment of the present application, since the outer surface of the ball seat 123 and the inner surface of the support seat 11 formed by the cavity 111 fit each other, when the adjustment component 13 adjusts the position of the first end 121 or the second end 122 in the cavity 111, at the first end 121 and the second end 122, the end that is not socketed with the ball seat 123 moves on the arc spherical surface with the ball seat 123 as the center, and the position of the end socketed with the ball seat 123 is relatively stable. Therefore, it is easier for the operator to grasp the adjustment rules when adjusting the laser emission direction of the laser emission structure 1, thereby improving the efficiency of adjusting the laser emission direction of the laser emission structure 1.

[0051] like Figure 2 As shown, the ball seat 123 and the laser 12 can be detachably connected or fixedly connected.

[0052] In one possible implementation, Figure 2 As shown, a receiving groove 113 is provided on the inner surface of the support seat 11 formed by the cavity 111 , and the end of the elastic member 131 away from the laser 12 is located in the receiving groove 113 .

[0053] In the embodiment of the present application, the end of the elastic member 131 away from the laser 12 is located in the receiving groove 113, which can reduce the possibility of the elastic member 131 being damaged due to bending and the like during elastic deformation.

[0054] In one possible implementation, Figure 2 As shown, the receiving groove 113 passes through the outer surface of the support seat 11, and a top plate 114 is provided at the receiving groove 113 on the outer surface of the support seat 11. The top plate 114 is detachably connected to the support seat 11, and the end of the elastic member 131 away from the laser 12 is connected to a side of the top plate 114 close to the receiving groove 113.

[0055] In the embodiment of the present application, the setting of the top plate 114 allows the elastic member 131 to be taken out of the support seat 11 by directly removing the top plate 114 relative to the support seat 11 when replacing the elastic member 131, thereby facilitating the repair and maintenance of the elastic member 131.

[0056] It should be noted that Figure 2 There is no top plate at h in the figure, but the top plate is replaced by one side of a support base in another laser emitting structure 1 to simplify the structure.

[0057] like Figure 2 As shown, the top plate 114 is used to cover the port of the accommodating groove 113 in the outer surface of the support seat 11, and the top plate 114 and the support seat 11 can be connected by bolts or the like.

[0058] like Figure 2As shown, the end of the elastic member 131 away from the laser 12 is fixedly connected or detachably connected to a surface of the top plate 114 close to the receiving groove 113 .

[0059] In one possible implementation, Figure 2 As shown, at least one laser emitting structure 1 among the multiple laser emitting structures 1 includes a spectrometer 14. For the laser emitting structure 1 including the spectrometer 14, the angle between the laser emitted by the laser 12 included in the laser emitting structure 1 and the spectrometer 14 is not a right angle, and at least a portion of the laser emitted by the laser 12 included in the laser emitting structure 1 is reflected by the spectrometer 14 and then emitted outside the laser emitting structure 1.

[0060] In the embodiment of the present application, by setting up the beam splitter 14, the therapeutic laser can be emitted toward the eye to be treated after passing through the beam splitter 14, and thus the part of the therapeutic laser after passing through the beam splitter 14 can overlap with the part of the laser emitted by the laser 12 after being reflected by the beam splitter 14, so as to facilitate the determination of the relative position of the therapeutic laser emitting component 2 and the laser emitting device when producing the treatment head.

[0061] For example, Figure 3 As shown, the laser emitting device includes two laser emitting structures 1. The path of laser emission by the laser 12 of one laser emitting structure 1 is a dotted line d, and the path of laser emission by the laser 12 of the other laser emitting structure 1 is a dotted line e. The laser emission path of the part of the therapeutic laser after passing through the spectrometer 14 is also a dotted line e. d and e are on the same plane and have an intersection.

[0062] In addition, a portion of the therapeutic laser can pass through the beam splitter 14, and the other portion can be reflected by the beam splitter 14 to the side of the beam splitter 14 away from the laser 12. Then, by detecting the light intensity and other data of the portion of the therapeutic laser reflected by the beam splitter 14, the light intensity and other data of the portion of the therapeutic laser that passes through the beam splitter 14 and is emitted to the eye to be treated can be obtained, thereby achieving more accurate monitoring of the treatment process.

[0063] like Figure 2 As shown, the angle between the laser emitted by the laser 12 included in the laser emitting structure 1 and the beam splitter 14 can be 45°, 50% of the laser emitted by the laser 12 included in the laser emitting structure 1 penetrates the beam splitter 14, and the other 50% is reflected by the beam splitter 14 and then emitted outside the laser emitting structure 1.

[0064] In one possible implementation, Figure 2As shown, the top member 132 is a bolt, and the bolt is threadedly connected to the support seat 11. Since the bolt is threadedly connected to the support seat 11, the adjustment component 13 can be fine-tuned, thereby improving the accuracy of adjusting the position of the second end 122 of the adjustment component 13 in the cavity 111. In addition, the direction of the laser emitted by the laser emitting structure 1 can be adjusted by simply screwing the bolt in or out relative to the support seat, which has a simple structure and a clear adjustment direction.

[0065] In one possible implementation, Figure 2 As shown, the support seats 11 included in the multiple laser emitting structures 1 are detachably connected to each other. For example, the support seats 11 included in the multiple laser emitting structures 1 in the laser emitting device can be bolted to each other.
