However, the description of the specific configuration of the control unit will be omitted from the description of the control unit of the second embodiment below.

Hereinafter, a phototherapy apparatus according to a second embodiment of the present invention will be described with reference to FIGS. 6 to 12. FIG. However, components and corresponding technical features corresponding to those of the above-described embodiments are replaced with those described in the first embodiment in order to avoid duplication of description.

6 is a perspective view showing a state of a phototherapy apparatus according to a second embodiment of the present invention. 6, the phototherapy apparatus 10 according to the present embodiment includes the diagnosis and treatment system 20 and the patient support unit 30 as in the above-described embodiment. The diagnosis and treatment system 20 includes a frame 40 and a diagnostic unit 100 and a treatment unit 200 installed in the frame. The patient support unit 30 includes a sliding and / And a supporter (32). The phototherapy apparatus 10 according to the present embodiment is different from the above embodiments in the installation and operation structure of the diagnosis and treatment system 20 and the structure of the diagnosis unit 100 and the treatment unit 200 And can be configured differently.

FIG. 7 is an exploded perspective view of the diagnostic and treatment system of FIG. 6, FIG. 8 is a cross-sectional view of the diagnostic and treatment system in the A direction, and FIG. Fig.

7, the frame 40 of the phototherapy apparatus 10 according to the present embodiment includes a frame body 44 having an annular structure, a first rotary panel 45 forming one side surface of the frame, And a second rotation panel (46) forming the other side surface of the frame. The first rotating panel 45 and the second rotating panel 46 are installed on both sides of the frame body 44 so as to be rotatable about the central axis of the frame 40. Here, the first rotating panel 45 and the second rotating panel 46 are configured to be independently rotatable by separate driving members (not shown).

7 to 9, the treatment unit 200 of the phototherapy apparatus 10 according to the present embodiment includes two treatment light irradiation units 210 and 220 ), And the treatment is performed by irradiating light to the affected part of the patient and delivering energy.

Here, the first treatment light irradiation unit 210 is installed on the first rotary panel 45, and the second treatment light irradiation unit 220 is installed on the second rotation panel 46. Therefore, the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 are moved in position as the first rotation panel 45 and the second rotation panel 46 rotate, Light can be irradiated. The first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 can independently rotate the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 independently of each other because the first rotation panel 45 and the second rotation panel 46 are independently rotatable. The operation can be performed while changing.

The treatment unit 200 according to the present embodiment may further include beam stoppers 230 and 240 that block the treatment light emitted from the treatment light irradiation units 210 and 220. In the case of the above-described embodiment, the treatment light irradiated from the treatment light irradiation unit is transmitted to the other components at the opposed positions through the patient, which may cause damage to the system. Therefore, in the present embodiment, a beam stopper is further provided at a position opposite to the treatment light irradiation unit, thereby preventing other components from being damaged by the treatment light.

7, the first beam stopper 230 is disposed at a position 180 degrees away from the first treatment light irradiation unit 210 along the circumferential direction of the first rotary panel 45, And blocks the therapeutic light emitted from the light source 210. The second beam stopper 240 is disposed at a position 180 degrees away from the second treatment light irradiation unit 220 along the circumferential direction of the second rotary panel 46 and irradiated from the second treatment light irradiation unit 220 Thereby blocking the curing light.

In the meantime, the diagnosis unit 100 according to the present embodiment is configured to diagnose the position and state of the affected part by irradiating light to acquire the affected part image of the patient, as in the above-described embodiment, And a photodetector unit 120. The diagnostic light irradiation unit 110 includes two diagnostic light irradiation units 111 and 112 and the diagnostic light detection unit 120 may include two diagnostic light detection units 121 and 122. [ Therefore, the diagnosis unit 100 according to the present embodiment is also capable of acquiring a lesion image in various directions, and is advantageous in that a three-dimensional image can be constructed quickly using the lesion image.

However, in the above-described embodiment, two diagnostic light irradiation units are provided on the first frame and the third frame, respectively, and are disposed apart from each other in the rotational axis direction (key direction of the patient) of the frame. The two diagnostic light irradiation units 111 and 112 can be configured to be arranged along the circumferential direction on the same section of the annular frame.

In this case, it is more advantageous to form an angle at which the two diagnostic light beams irradiated from the two diagnostic light irradiation units 111 and 112 cross each other, as compared with the above-described embodiment, It is possible. In addition, since each diagnostic light is irradiated in the lateral direction of the patient, there is an advantage in favor of image acquisition in consideration of the human body structure.

Specifically, as shown in Figs. 7 and 8, the first diagnostic light irradiation unit 111 and the second diagnostic light irradiation unit 112 are connected to a first treatment light irradiation unit (not shown) provided on the first rotary panel 45 210, respectively. The first diagnostic light detecting unit 121 and the second diagnostic light detecting unit 122 may be installed on both sides of the first beam stopper 230, respectively. Therefore, the first diagnostic light irradiation unit 111 and the first diagnostic light detection unit 121, and the second diagnostic light irradiation unit 112 and the second diagnostic light detection unit 122 are connected to the first rotary panel 45 And 180 degrees apart from each other along the circumferential direction.

In this case, since the first diagnostic light irradiation unit 111 and the second diagnostic light irradiation unit 112 irradiate the diagnostic light in a state of being separated from the width of the first treatment light irradiation unit 210 or more, Images can be obtained. Further, each of the diagnostic light irradiation units 111 and 112 and the diagnostic light detection units 121 and 122 are provided with legs that can be extended to both sides of the first treatment light irradiation unit 210 and the first beam stopper 230, respectively It is also possible to arrange to adjust the irradiation direction of the diagnostic light. In such a phototherapy apparatus, it is advantageous for the diagnosis of the lesion and the construction of the three-dimensional image that the angle formed by intersection of the two diagnostic lights is in the range of 60 degrees to 110 degrees.

Hereinafter, the operation of the diagnosis unit and the irradiation unit of the optical therapy apparatus according to the present embodiment will be schematically described with reference to FIGS. 10 to 12. FIG.

FIG. 10 is a schematic view showing an example of the operation of the diagnosis section of the optical therapy apparatus of FIG. 6; 10, the diagnosis unit 100 of the phototherapy apparatus 10 according to the present embodiment includes a first diagnostic light irradiation unit 111 and a second diagnostic light irradiation unit 112 at a fixed position It is possible to acquire two projection images in different directions by using the two projection images. As the first rotary panel 45 moves, the first diagnostic light irradiation unit 111 and the second diagnostic light irradiation unit 112 acquire images in various directions continuously while moving their positions, It is also possible to form a three-dimensional image. Furthermore, it is also possible to secure a real-time image during the treatment through the diagnosis unit during the treatment light proceeding by the treatment unit 200.

FIG. 11 is a schematic view showing an example of a treatment section of the phototherapy apparatus in FIG. 6, and FIG. 12 is a schematic view showing another example of a treatment section of the phototherapy apparatus in FIG. 6.

As shown in Fig. 11, the treatment unit 200 according to the present embodiment includes two treatment light irradiation units 210 and 220, so that it is possible to simultaneously irradiate two lights to the affected part of the patient. At this time, in the first treatment light irradiation unit 210, the irradiation position is adjusted by rotating the first rotary panel 45, and the irradiation position is adjusted by rotating the second treatment light irradiation unit 220 . The first and second treatment light irradiation units 210 and 220 can be simultaneously irradiated to the same lesion from different directions to improve the treatment effect and shorten the treatment time. In addition, the first and second treatment light irradiation units 210 and 220 can be simultaneously irradiated to the foreign parts at different positions, thereby shortening the treatment time.

On the other hand, as described above, the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 are installed in the first rotation panel 45 and the second rotation panel 46, which are independently rotatable , The treatment light can be independently controlled to be irradiated. Therefore, when irradiation of treatment light is required at various positions on the affected area T of the patient P, as shown in Fig. 12, while one of the treatment light irradiation units irradiates the treatment light, the remaining treatment light irradiation unit By moving to the next irradiation position, the treatment time can be shortened.

Although the treatment unit 200 according to the present embodiment is capable of adjusting the position by rotation of the first rotary panel 45 and the second rotary panel 46, the first and second treatment light irradiation units 210, The angle between the treatment light beams irradiated from the first and second treatment light irradiation units 210 and 220 may be limited by the sizes of the first and second beam stoppers 230 and 240 and the first and second beam stoppers 230 and 240 themselves. It may be appropriate to configure the angle between the treatment light irradiated from the two treatment light irradiation units as a result of constructing the prototype equipment to be formed in a range of 30 degrees or more and 150 degrees or less.

Fig. 13 is a block diagram schematically showing each component of the phototherapy apparatus in Fig. 6. Fig. As shown in FIG. 13, the respective components of the diagnostic and treatment system 20 constituting the phototherapy apparatus 10 and the patient support section 30 can be controlled by the control section 300, respectively. Specifically, the patient support unit 30 may perform a sliding operation or a swiveling operation under the control of the control unit 300 to move the patient's position or adjust the posture. The rotation of the first and second rotary panels 45 and 46 of the frame 40 can be controlled to adjust the positions of the diagnosis unit 100 and the treatment unit 200 respectively. Here, the control unit 300 controls the first rotary panel 45 and the second rotary panel 46 to rotate independently of each other. Therefore, only the first rotary panel 45 is rotated to adjust only the positions of the diagnosis unit 100, the first treatment light irradiation unit 210 and the first beam stopper 230, or only the second rotary panel 46 The diagnostic unit 100 installed on each rotary panel by rotating only the positions of the second treatment light irradiation unit 220 and the second beam stopper 240 or by rotating both the first and second rotary panels 45 and 46, And the position of each component constituting the treatment unit 200 can be simultaneously adjusted.

The control unit 300 controls the position of the diagnosis unit 100 and drives the first diagnostic light irradiation unit 111 and the second diagnostic light irradiation unit 112 to irradiate the irradiated light to the affected part of the patient Can be controlled. Thereby, the image information detected by the first diagnostic light detecting unit 121 and the second diagnostic light detecting unit 122 is transmitted to the processor 400, and the processor 400 obtains the two-dimensional projection image from this information Alternatively, a three-dimensional image can be constructed using a plurality of images in different directions.

Further, the control unit 300 may control the treatment operation of the treatment unit according to the set treatment pattern. That is, the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 of the treatment unit 200 are driven under the control of the control unit 300 to selectively irradiate the treatment light. At this time, the control unit 300 can independently control the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220, and determines whether or not the treatment light is irradiated, the output of the treatment light irradiated from the irradiation unit, It is possible to control the time. Therefore, each of the treatment light irradiation units 210 and 220 can irradiate treatment light corresponding to a dosage set to the affected part T of the patient P at a predetermined position.

At this time, the patterns in which the treatment light irradiation units 210 and 220 are controlled can be set by the processor 400 based on the image of the affected part acquired by the diagnosis unit 100, It may be determined by the user based on the information input from the outside based on the image or information already diagnosed through the other diagnostic equipment. Then, the control unit 300 can control the treatment operation of the treatment unit based on this pattern.

Although the control of the components of the optical therapy apparatus by the control unit has been described above, it has been described based on the configuration of the optical therapy apparatus according to the present embodiment, but the present invention is not limited thereto. For example, in the case of the optical therapy apparatus having the configuration according to the first embodiment, the control unit may control the positions of the diagnosis unit and the treatment unit by driving the first frame, the second frame, and the third frame, It is needless to say that the control contents can be changed so as to correspond to the respective structures.

Hereinafter, a control method of the optical therapy apparatus according to the present embodiment will be described in detail with reference to FIGS. 14 to 16. FIG. First, Fig. 14 is a flowchart showing a control method of the optical therapy apparatus of Fig.

As shown in FIG. 14, the control method of the optical therapy apparatus according to the present embodiment includes steps of acquiring a diagnostic image (S10), setting a treatment pattern (S20), and irradiating treatment light (S30) And the like.

First, the image acquiring step (S10) can be configured so that the control unit 300 drives the diagnosis unit 100 to acquire an image of the affected part of the patient. For example, the control unit rotates the first rotary panel 45 on which the diagnosis unit is installed to arrange the first and second diagnostic light irradiation units 111 and 112 of the diagnosis unit at proper positions, It is possible to irradiate the diagnosis light and acquire the affected part image from the patient.

In this step, the controller 300 can control the diagnosis light irradiation units 111 and 112 to be able to acquire a two-dimensional image in the corresponding direction while being fixed at a specific position. In addition, the control unit 300 controls the diagnostic unit 100 to rotate the first rotary panel 45 while obtaining the image by irradiating the diagnostic light, thereby continuously controlling the irradiation direction of the diagnostic light, It is also possible to do. In this case, the processor 400 may perform an operation of constructing a three-dimensional image of the affected part of the patient using the plurality of images.

The lesion image of the patient obtained in this step can be used for diagnosing the position and shape of the lesion, and can be used for determining the treatment pattern of the lesion.

The treatment pattern setting step S20 is a step of setting patterns such as the position of the affected part irradiated with the treatment light, the amount of the treatment light to be irradiated and the order to be irradiated, before the treatment light is irradiated.

In this step, the processor 400 itself determines a treatment pattern based on the affected image of the patient obtained through the diagnostic image obtaining step (S10), or a method in which the operator sets a pattern based on the affected part image and inputs it . ≪ / RTI >

However, the present invention is not limited to this, and it is also possible that the treatment pattern is set in advance through a separate diagnostic device before the diagnosis image acquisition step It is also possible to set it.

When the treatment pattern is determined, the treatment light irradiation step (S30) is performed. In this step, the control unit 300 operates the first and second rotary panels 45 and 46 in accordance with the determined treatment pattern to detect the position of the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 And the treatment can be proceeded by controlling the output and irradiation time of the treatment light irradiated from each irradiation unit.

Since the optical therapy apparatus 10 according to the present embodiment includes two treatment light irradiation units 210 and 220 whose position and treatment light characteristics are independently controlled, It is possible. The concrete operation contents of this step will be described in more detail using the following examples.

FIG. 15 is a schematic view showing an example of the treatment pattern in FIG. 14, and FIG. 16 is a flowchart showing the operation contents of main components in the treatment light irradiation step according to the treatment pattern in FIG.

The treatment pattern can be determined by irradiating the treatment light to the affected area T of the patient P in four different positions P1, P2, P3 and P4, as shown in Fig. Here, the position where the therapeutic light is irradiated is referred to as a first position P1, a second position P2, a third position P3, and a fourth position P4 according to the order in which light is irradiated. At this time, the control unit controls the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 so as to minimize the time required for changing the irradiation position in the treatment light irradiation step, It is possible to control to alternately irradiate the treatment light. That is, the first treatment light irradiation unit 210 irradiates the treatment light at the first position P1 and the third position P3, the second treatment light irradiation unit 220 irradiates the treatment light at the second position P2, The treatment pattern may be set to irradiate the treatment light at the fourth position P4. At this time, the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 are limited to be adjacent to each other due to the size of the treatment light irradiation unit itself as described above. Therefore, in order for the first treatment light irradiation unit 210 and the second treatment light irradiation unit 220 to alternately irradiate the treatment light, the treatment positions temporally adjacent to each other (for example, The angle between the second position P2, the second position P2 and the third position P3, the third position P3 and the fourth position P4) is in the range of 30 degrees to 150 degrees, (See Fig. 15).

The step of irradiating the treatment light corresponding to this treatment pattern can be started with the first treatment light irradiation unit 210, the second treatment light irradiation unit 220 and the diagnosis unit 100 being disposed at the initial position. At this time, the initial position of the first treatment light irradiation unit 210 and the diagnosis unit 100 may be X1, and the initial position of the second treatment light irradiation unit 220 may be X2 (S31).

The first treatment light irradiation unit 210 is first moved to the first position P1 to irradiate the treatment light to the first position P1 and then the first treatment light irradiation unit 210 is moved to the first position P1, dosage can be irradiated. At this time, the second treatment light irradiation unit 220 can be controlled to move to the second position P2 to irradiate the treatment light to the next position. Then, the diagnosis unit 100 can acquire a real-time image of the affected part treated by the first treatment light irradiation unit 210 (S32).

On the other hand, when the treatment light irradiation at the first position P1 is finished, the treatment light of the second dose can be irradiated to the affected part through the second treatment light irradiation unit 220 located at the second position P2. At this time, the first treatment light irradiation unit 210 can be controlled to move to the third position P3 so that the treatment at the third position P3 can proceed immediately after the treatment at the second position P2 is finished have. Then, the diagnosis unit 100 can acquire a real-time image of the affected part treated by the second treatment light irradiation unit 220 (S33).

When the treatment light irradiation at the second position P2 is finished, the treatment light of the third dose can be irradiated to the affected part through the first treatment light irradiation unit 210 located at the third position P3. At this time, the second treatment light irradiation unit 220 can be controlled to move to the fourth position P4 so that the treatment can be proceeded at the fourth position P4 immediately after the treatment at the third position is finished. Then, the diagnosis unit 100 can acquire a real-time image of the affected part treated by the first treatment light irradiation unit 210 (S34).

When the treatment light irradiation at the third position P3 is finished, the second treatment light irradiation unit 220 located at the fourth position P4, which is the final position, can irradiate the treatment light of the fourth dose. Then, the diagnosis unit 100 can acquire a real-time image of the affected part treated by the second treatment light irradiation unit 220 (S35).

As described above, the phototherapy apparatus according to the present embodiment is provided with two treatment light irradiation units, and it is advantageous in that the time required for treatment can be remarkably shortened by controlling light to be irradiated alternately at different positions.

However, the present invention is not limited to this, and it is possible to perform the treatment of the above-mentioned phototherapy apparatus by two treatments depending on the position of the affected part and the necessary treatment contents It is possible to control the light irradiation unit to be driven simultaneously, and it is also possible to perform the treatment by operating only one of the treatment light irradiation units.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It should be decided by scope.
