Description

Technical Field

[0001] The invention belongs to the medical field, and in particular relates to a device and a system for detecting and positioning laser. Background Art

[0002] During radiotherapy, positioning is an extremely important part of radiotherapy and an important guarantee for the correct completion of the treatment plan. When positioning for accelerator radiotherapy, the positioning is carried out according to the laser line emitted by the laser. In the radiotherapy room where the accelerator is placed, three lasers are generally installed, one on each side wall of the treatment bed and one on the end wall of the treatment bed; the lasers on both sides of the treatment bed emit cross-shaped laser lines, which are laser lines parallel to the horizontal plane and laser lines perpendicular to the horizontal plane, and the intersection points of the cross-shaped laser lines all pass through the isocenter of the accelerator; the laser on the end side of the treatment bed emits a straight laser line perpendicular to the horizontal plane, and the straight laser line also passes through the isocenter of the accelerator. At the same time, the lasers emitted by the three lasers are all wide-angle laser lines (for example, the effect formed by the cross-shaped laser line emitted by the laser on the side of the treatment bed can be regarded as two mutually perpendicular laser planes passing through the laser).

[0003] However, due to interference from the external environment, the installation position of the laser and the light-emitting components inside the laser are very likely to shift, causing the laser surface to shift from the correct position. When the laser device deviates from the working position, the laser may be involved in positioning marking or positioning treatment for tumor patients, which will reduce the treatment effect of tumor patients and cause greater damage to the normal tissues of tumor patients.

[0004] In the prior art, the operator can set a reference line at the position directly opposite the laser surface. When the laser surface is irradiated onto the reference line, the operator can determine whether the reference line coincides with the laser surface, thereby determining whether the laser surface has shifted. However, when the installation position of the laser and the light-emitting components inside the laser are offset up and down by the same amount (for example, the light-emitting components inside the laser are offset upward, and the installation position of the laser is offset downward), the laser has actually shifted, but when the laser surface is irradiated onto the reference line, it will still coincide with the reference line. Therefore, the reference line can no longer determine whether the laser surface is offset, and the operator cannot grasp the state of the laser surface, which poses a safety risk. Summary of the invention

[0005] The present invention provides a device and a system for detecting positioning laser, which aims to solve the shortcomings of the existing laser surface detection method.

[0006] In order to achieve the above-mentioned object, the present invention provides a device for detecting positioning laser, comprising a first detection panel and a second detection panel, wherein the first detection panel and the second detection panel are arranged front and back, and the first detection panel and the second detection panel are used for uniformly irradiating the laser surface from the front;

[0007] The first detection panel and the second detection panel are both provided with detection components, and the detection components are used to detect whether the laser surface is offset.

[0008] This solution is provided with a first detection panel and a second detection panel. When the laser surface is irradiated onto the first detection panel and the second detection panel, the detection components located on the first detection panel and the second detection panel can detect the irradiation position of the laser surface, and then determine whether the laser surface is deviated.

[0009] In addition, if only the installation position of the laser or the light-emitting components inside the laser are offset, both the first detection panel and the second detection panel can detect the offset of the laser surface; if the installation position of the laser and the light-emitting components inside the laser are offset at the same time, and the upper and lower offset amounts of the installation position of the laser and the light-emitting components inside the laser are the same, the first detection panel can no longer detect the offset of the laser surface, and the second detection panel can play the role of detecting whether the laser surface is offset.

[0010] Furthermore, the detection component in Solution 1 is specifically a photosensitive sensor, and the photosensitive sensor is evenly installed on the first detection panel and the second detection panel, and the photosensitive sensor is used to sense the irradiation position of the laser surface.

[0011] When the laser surface irradiates the photosensitive sensor, the photosensitive sensor can receive the light signal of the laser surface. At the same time, since the photosensitive sensors are evenly installed on the first detection panel and the second detection panel, by comparing the position change of the laser surface irradiated forward and backward, it can be determined whether the laser surface is offset.

[0012] Furthermore, in order to ensure that both the first detection panel and the second detection panel can receive the irradiation of the laser surface, the photosensitive sensors in the first solution are arranged evenly in a circular shape on the first detection panel, and the photosensitive sensors are arranged evenly in a ring shape at the edge of the second detection panel;

[0013] Alternatively, the light sensitive sensors may be evenly arranged in a circular shape on the surfaces of the first detection panel and the second detection panel.

[0014] Furthermore, the detection component in the second solution is a reference line, the first detection panel and the second detection panel are both provided with the reference line, and the reference lines of the first detection panel and the second detection panel are parallel to each other and located in the same plane.

[0015] When the laser surface is irradiated onto the first detection panel and the second detection panel, by comparing whether the laser surface coincides with the reference lines on the first detection panel and the second detection panel, it can be determined whether the laser surface is offset. In addition, reference lines are provided on both the first detection panel and the second detection panel, so that when the installation position of the laser and the light-emitting components inside the laser are offset up and down by the same amount, the reference line on the second detection panel can also detect whether the laser surface is offset.

[0016] Furthermore, in order to ensure that both the first detection panel and the second detection panel can be irradiated by the laser surface, in this solution, the area of ​​the first detection panel can be set to be smaller than that of the second detection panel, and the first detection panel is located in front of the second detection panel.

[0017] When the area of ​​the first detection panel is smaller than the area of ​​the second detection panel, the second detection panel will not be blocked by the first detection panel, thereby ensuring that the second detection panel can be irradiated by the laser surface.

[0018] Alternatively, the first detection panel may be a transparent panel, and the first detection panel is located in front of the second detection panel.

[0019] When the first detection panel is a transparent panel, the laser surface can pass through the first detection panel and then irradiate the second detection panel.

[0020] Furthermore, in order to enable the laser surface to stably irradiate the first detection panel and the second detection panel, the present solution also includes a main shaft and a steering mechanism. The first detection panel and the second detection panel are both installed on the steering mechanism. The steering mechanism is installed on the main shaft. The steering mechanism is used to drive the first detection panel and the second detection panel to rotate horizontally.

[0021] The main shaft is used to support the first detection panel and the second detection panel, and the steering mechanism is used to rotate the first detection panel and the second detection panel so that the first detection panel and the second detection panel face the laser surface to ensure that the laser surface irradiates the first detection panel and the second detection panel.

[0022] Furthermore, the steering mechanism in the present embodiment specifically includes a first bearing and a first transmission assembly, the inner ring of the first bearing is used for installing the main shaft, the outer ring of the first bearing is used for installing the first detection panel and the second detection panel, the outer ring of the first bearing cooperates with the first transmission assembly, and the first transmission assembly is used to drive the outer ring of the first bearing to rotate.

[0023] When the first transmission component moves, the first bearing can rotate, thereby causing the first detection surface and the second detection surface mounted on the first bearing to rotate. When the first detection surface and the second detection surface rotate, they can correspond to the laser surface, ensuring that the laser surface irradiates the first detection surface and the second detection surface.

[0024] Furthermore, since the laser surface emitted by the laser is in a vertical or horizontal state, in order to enable the first detection panel and the second detection panel to correspond to the laser surface, the main shaft in this solution is connected to a vertical mechanism, and the vertical mechanism is used to adjust the main shaft to a vertical state.

[0025] When the main axis is in a vertical state, the irradiated area on the first detection panel and the second detection panel is larger, thereby ensuring that the laser surface stably irradiates the first detection panel and the second detection panel.

[0026] Furthermore, the vertical mechanism in the present embodiment includes a fixed component, a second bearing, a semi-annular rack, a driver and a second transmission assembly, the main shaft is mounted on the fixed component through a spherical joint, the fixed component is fixedly arranged, the inner ring of the second bearing is mounted on the fixed component, the semi-annular rack is mounted on the bottom end of the outer ring of the second bearing, the semi-annular rack is matched and connected with the driver mounted on the main shaft, and the second bearing is driven to rotate by the second transmission assembly.

[0027] In this solution, by providing a second bearing and a semi-annular rack, the main shaft can move spherically, thereby enabling the main shaft to be adjusted to a vertical state.

[0028] The present invention also provides a system for detecting laser positioning equipment, including the above-mentioned detection device and a control terminal, wherein the detection device corresponds one-to-one to the laser surface emitted by the laser, the detection device is connected to the control terminal, and the control terminal is used to receive the detection result of the detection device.

[0029] The detection devices correspond to the laser surfaces emitted by the lasers one by one, so when the laser surfaces are offset, they can be detected by the detection devices. The detection devices are then connected to the control terminal, which is used to receive the detection results of the detection devices, so that both laser surfaces can be detected in real time.

[0030] The beneficial effect of the present invention is that in this solution, by providing the first detection panel and the second detection panel, the tilt of the laser surface can be detected.

[0031] At the same time, by setting up the first detection panel and the second detection panel, the two detection panels cooperate with each other, so that when the installation position of the laser and the light-emitting components inside the laser are offset up and down by the same amount, the laser surface can also be detected to be offset.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiment more clear, the present invention is further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The embodiment is basically as shown in the attached Figure 1 To Attachment Figure 6As shown, a device for detecting positioning laser includes a first detection panel 1 and a second detection panel 2. The first detection panel 1 and the second detection panel 2 are circular, and the first detection panel 1 and the second detection panel 2 are arranged front and back. When the laser surface 9 is emitted from the front of the first detection panel 1 and the second detection panel 2, the laser surface 9 can be uniformly irradiated to the first detection panel 1 and the second detection panel 2. The first detection panel 1 and the second detection panel 2 are connected together by a connecting component. The first detection panel 1 and the second detection panel 2 are arranged in parallel.

[0043] The first detection panel 1 and the second detection panel 2 are both provided with detection components. The detection components can detect the laser surface 9 individually or in cooperation with each other.

[0044] It should be noted that: if the installation position of the laser emitter or the light-emitting components inside the laser emitter are offset individually, and the installation position of the laser emitter and the light-emitting components inside the laser emitter have different vertical offsets (for example, the amount of downward offset of the installation position of the laser emitter is inconsistent with the amount of upward offset of the light-emitting components inside the laser emitter), the laser surface 9 can be detected using only the detection components on the first detection panel 1. If the installation position of the laser emitter and the light-emitting components inside the laser emitter have the same offset value (for example, the amount of downward offset of the installation position of the laser emitter is consistent with the amount of upward offset of the light-emitting components inside the laser emitter), the detection components in the first detection panel 1 and the second detection panel 2 need to cooperate to detect the laser surface 9.

[0045] The detection component in this embodiment may be a photosensitive sensor 3, which is evenly arranged on the first detection panel 1 and the second detection panel 2. The photosensitive sensor 3 may be a photoelectric sensor, and when the laser surface 9 irradiates the photoelectric sensor, the photoelectric sensor at the laser irradiation position can sense the laser, and then determine the irradiation position of the laser surface 9.

[0046] In this embodiment, the photosensitive sensors 3 may be arranged evenly in a circular shape on the first detection panel 1 , and the photosensitive sensors 3 may be arranged evenly in a ring shape on the second detection panel 2 .

[0047] Alternatively, the photosensitive sensors 3 may be arranged in a circular and uniform manner on both the first detection panel 1 and the second detection panel 2 .

[0048] It should be noted that if the light-sensitive sensors 3 are evenly arranged in a circular shape on the first detection panel 1 and the second detection panel 2 , a portion of the middle portion of the second detection panel 2 will be blocked by the first detection panel 1 .

[0049] The working process of detecting the laser surface 9 by the photosensitive sensor 3 is as follows: when the laser surface 9 is irradiated from the front of the first detection panel 1 and the second detection panel 2 onto the first detection panel 1 and the second detection panel 2, the photosensitive sensor 3 can receive the laser surface 9. Since the installation positions of the detection components on the first detection panel 1 and the second detection panel 2 are fixed, when the photosensitive sensors 3 at different positions receive the laser surface 9, the positions where the laser surface 9 is irradiated on the first detection panel 1 and the second detection panel 2 are determined.

[0050] In this embodiment, the first detection panel 1 can be arranged in front of the second detection panel 1. The first detection panel 1 has a smaller area than the second detection panel 2 and is located in the middle of the second detection panel 2, so that the laser surface 9 can irradiate the second detection panel 2.

[0051] Alternatively, the first detection panel 1 may be set as a transparent panel, so that the laser surface 9 can be irradiated onto the second laser surface 9 eventually.

[0052] This embodiment also includes a main shaft 5 and a steering mechanism 6. The steering mechanism 6 is mounted on the main shaft 5, and the first detection panel 1 and the second detection panel 2 are mounted on the steering mechanism 6. The main shaft 5 supports the steering mechanism 6. When the steering mechanism 6 rotates, the first detection panel 1 and the second detection panel 2 are driven to rotate horizontally at the same time.

[0053] It should be noted that the first detection panel 1 and the second detection panel 2 are adjusted in the opposite direction by providing the steering mechanism 6 , so that the first detection panel 1 and the second detection panel 2 can face the laser surface 9 .

[0054] The steering mechanism 6 in this embodiment includes a first bearing 601 and a first transmission assembly 602. The inner ring of the first bearing 601 is used for mounting the main shaft 5, and the outer ring of the first bearing 601 is used to support the first detection panel 1 and the second detection panel 2. At the same time, the outer ring of the first bearing 601 cooperates with the first transmission assembly 602, and the first transmission assembly 602 can drive the outer ring of the bearing to rotate, thereby causing the first detection panel 1 and the second detection panel 2 to rotate horizontally.

[0055] In this embodiment, the first transmission assembly 602 specifically includes a gear ring and a drive motor. The gear ring is fixedly arranged on the top of the outer ring of the first bearing 601, and the drive motor is fixedly installed on the main shaft 5, and the drive motor and the gear ring are meshed and connected with each other. When the drive motor rotates, the outer ring of the first bearing 601 will rotate through the drive of the gear ring. Since the first detection panel 1 and the second detection panel 2 are installed on the outer ring of the first bearing 601, the first detection panel 1 and the second detection panel 2 can finally achieve horizontal rotation.

[0056] At the same time, in this embodiment, the main shaft 5 is also directly connected to the vertical mechanism 7, and the vertical mechanism 7 is used to adjust the main shaft 5 to a vertical state. When the main shaft 5 is adjusted to a vertical state, it can ensure that the laser surface 9 can stably irradiate the first detection panel 1 and the second detection panel 2, and avoid the laser surface 9 being unable to irradiate the detection panel after the detection panel is tilted.

[0057] The vertical mechanism 7 in this embodiment includes a fixed component 702, a second bearing 701, a semi-annular rack 703, a driving motor and a second transmission assembly 705. The fixed component 702 is fixedly arranged, and can be specifically fixedly installed on the housing of a treatment machine or a simulation positioning machine. The main shaft 5 is rotatably connected to the fixed component 702 through a fisheye joint. The main shaft 5 can rotate around the fisheye joint as the center. The fixed component 702 is provided with a second bearing 701, and the fixed component 702 is installed on the inner ring of the second bearing 701. A semi-annular rack 703 is provided at the bottom of the outer ring of the second bearing 701. At the same time, the driving motor is installed on the main shaft 5 and meshes with the semi-annular rack 703. At the same time, the second bearing 701 cooperates with the second transmission assembly 705, and the second transmission assembly 705 can drive the outer ring of the second bearing 701 to rotate.

[0058] In this embodiment, the second transmission assembly 705 has the same structure as the first transmission assembly 602, and both include a gear ring and a drive motor. The gear ring is arranged on the top of the second bearing 701. The drive motor is arranged on the fixed component 702, and the drive motor and the gear ring are meshed with each other. When the drive motor rotates, the second bearing 701 will rotate through the transmission of the gear ring.

[0059] The working principle of the vertical mechanism 7 is as follows: when the entire device is installed, since the installation base may be in an inclined state, in order to ensure that the laser surface 9 can stably irradiate the first detection panel 1 and the second detection panel 2, the outer ring of the second bearing 701 can be driven to rotate, and since a semi-annular rack 703 is provided at the bottom of the outer ring of the second bearing 701, and the semi-annular rack 703 is connected to the main shaft 5 through a driving motor. Therefore, when the second bearing 701 rotates, the main shaft 5 will also rotate accordingly. Afterwards, the driving motor installed on the main shaft 5 can drive the main shaft 5 to move along the semi-annular rack 703, and finally make the main shaft 5 in a vertical state.

[0060] It should be noted that the vertical adjustment mechanism can not only adjust the main shaft 5 to a vertical state when the entire device is installed, but also can adjust the main shaft 5 to a vertical state after the entire device is offset.

[0061] In this embodiment, a level sensor is also provided on the main shaft 5, and the level sensor is used to detect whether the main shaft 5 is in a vertical state.

[0062] This embodiment also includes a moving mechanism 8. The moving mechanism 8 is used to drive the first detection panel 1 and the second detection panel 2 to move.

[0063] In this embodiment, the moving mechanism 8 is fixedly mounted on the steering mechanism 6, and the moving mechanism 8 is used to mount the first detection panel 1 and the second detection panel 2. The moving mechanism 8 can be a linear module. The first detection panel 1 and the second detection panel 2 are mounted on the linear module. When the linear module moves, the first detection panel 1 and the second detection panel 2 also move accordingly.

[0064] It should be noted that: since the laser surface 9 emitted by the laser is a cross-shaped laser surface 9. Therefore, in order to make the laser surface 9 correspond to the first detection panel 1 and the second detection panel 2. Therefore, when it is necessary to use the present device to detect the laser surface 9 in a vertical state, the linear slide in the device is horizontally set. The horizontally set linear slide can drive the first detection panel 1 and the second detection panel 2 to move in the horizontal direction, thereby ensuring that the vertical laser surface 9 can illuminate the first detection panel 1 and the second detection panel 2. When it is necessary to use the present device to detect the laser surface 9 in a horizontal state, the linear slide in the device is vertically set. The vertically set linear slide can drive the first detection panel 1 and the second detection panel 2 to move in the vertical direction, thereby ensuring that the horizontal laser surface 9 can illuminate the first detection panel 1 and the second detection panel 2.

[0065] A detection system using the above detection device includes the above detection device and a control terminal. At least two detection devices are provided, and they correspond to the two laser lines emitted by the laser. The detection device is connected to the control terminal. When the detection device detects that the laser surface 9 is offset, the control terminal can receive a signal.

[0066] The detection device can correspond to the laser surface 9 located on the side and top of the treatment room respectively, thereby realizing the detection of the laser surface 9 on the side and top of the treatment room.

[0067] The control terminal can be connected to an alarm, so when the detection device detects that the laser surface 9 is offset, the control terminal can issue an alarm.

[0068] Alternatively, the control terminal may also be connected to a laser device with an adjustment function, so that the control terminal can control the laser device to adjust itself.

[0069] Example 2

[0070] The difference between this embodiment and embodiment 1 is that Figure 7 and Figure 8As shown: the detection component is a reference line 4, and the reference line 4 is respectively arranged on the first detection panel 1 and the second detection panel 2, and the reference lines 4 are parallel to each other and located in the same plane.

[0071] The following is further detailed description through a specific implementation method: when the laser surface 9 is uniformly irradiated onto the first detection panel 1 and the second detection panel 2 from the front, the detection components on the first detection panel 1 and the second detection panel 2 can detect whether the laser surface 9 is offset.

[0072] It should be noted that if the reference line 4 is used for detection, an operator or a related camera mechanism is required to perform the detection. The camera mechanism can determine whether the laser surface 9 is offset by comparing the change in the front and rear positions of the laser surface 9.

[0073] It should be noted that, since the laser surface 9 emitted by the laser is a cross-shaped laser surface 9. Therefore, when the device is used to detect the vertical laser surface 9, the reference line 4 in the device is in a vertical state, so that the laser surface 9 can correspond to the reference line 4; when the device is used to detect the horizontal laser surface 9, the reference line 4 in the device is in a horizontal state, so that the laser surface 9 can correspond to the reference line 4.

[0074] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
