Description

  The present invention relates to an irradiation apparatus and a program.

  There is a technique of using an optical beam such as a laser during surgery. As an example, there is a method of using a femtosecond laser having a pulse width (pulse period) of about 100 femtoseconds to about 10 picoseconds in ophthalmic surgery. This technique was initially targeted at LASIK surgery, but in recent years it has been extended to cataract surgery. In Patent Document 1 below, when an incision is made in a lens capsule of a patient using a femtosecond laser, an asymmetric feature is added to the incision or the intraocular lens so that the intraocular lens is accurately seated in the capsule. Techniques aimed at achieving this are disclosed.

JP 2012-91053 A

  When incising human tissue, there is a case where no particular attention is paid to the cross-sectional shape of the incision. For example, when the cornea is incised in the prior art, the cross-sectional shape of the incision (however, the cross-section is the cross-section in the direction crossing the direction of incision from the front surface to the back surface of the cornea. )) Seems to have received no particular attention. Even when the cornea is incised with a laser as in Patent Document 1, the cross-sectional shape of the incision is not particularly taken into consideration, and is considered to be, for example, a simple linear shape.

  However, according to the knowledge obtained by the present inventor, the cross-sectional shape of the incision is not limited to a straight line in the incision of the cornea, and an effect that has not been obtained in the past can be achieved by making the shape more appropriate. For example, if the cross-sectional shape is an incision with an arc shape or an inverted V shape, the convex side of both sides of the incision will fall toward the inside of the eye when the intraocular lens is inserted into the eye after the incision. Therefore, it is possible to achieve effects such as suppression of stretching of the incision and ease of self-closing of the incision.

  Therefore, in view of the above, the problem to be solved by the present invention is to provide an irradiation apparatus and a program that can appropriately set the cross-sectional shape when incising a human tissue by beam irradiation.

In order to solve the above-described problems, an irradiation apparatus according to the present invention includes an output unit that outputs a surgical beam having a function of incising the cornea of the eye, and a cornea of the eye by the surgical beam output from the output unit. Control means for controlling at least the direction of irradiation of the surgical beam so as to form an incision for inserting an intraocular lens into the eye, penetrating from the outer surface to the inner surface, and the cornea in the incision When the intraocular lens is inserted through the incision, the cross-sectional shape in a direction intersecting with the direction of progression from the outer surface opening to the inner surface opening collapses from the outer surface of the cornea to the inner surface side. Setting means for receiving an input from a user who sets such a convex shape to a linear shape other than a linear shape such that the convex shape is a shape formed on at least one of both sides of the incision. , The setting means, display means for displaying an image of the treatment site, and superimposed on the image of the treatment site which is displayed by the display means, progression path extending from the outer surface of the cornea of the eye in the incision to the inside surface And an overlap setting means for receiving an input for setting the shape of the incision and a cross-sectional shape in a direction intersecting the advance path in the incision, the overlap setting means depending on a position on the advance path in the incision It is possible to accept a cross-sectional shape that changes the cross-sectional shape .

  The membranous tissue may be a membranous tissue in the eye. As a result, in the incision of the membranous tissue of the eye, effects such as suppression of incision extension when the incision is opened and an instrument is inserted, and self-closing of the incision wound are achieved.

  The membranous tissue may be the cornea of the eye. As a result, in the incision of the cornea of the eye, effects such as suppression of incision extension when opening the incision and inserting an instrument, and facilitating self-closing of the incision are achieved.

  Further, the linear shape other than the linear shape is a convex shape that collapses from one side of the first surface and the second surface to the other side when an object is inserted through the incision. However, it is good also as a shape formed in at least one of the both sides of the said incision. As a result, the formation of the convex shape achieves effects such as suppression of incision stretching when the incision is opened and an instrument is inserted, and facilitation of self-closing of the incision.

  The setting means may set the cross-sectional shape of the incision according to a position between the first surface and the second surface of the incision. Thus, by appropriately setting the cross-sectional shape according to the position in the incision, effects such as suppression of incision extension in the case of opening an incision and inserting an instrument, facilitating self-closing of the incision, etc. Is achieved.

  The surgical beam may be a femtosecond laser. Thereby, in the incision using the femtosecond laser, effects such as suppression of the incision extension when opening the incision and inserting the instrument, and facilitating the self-closing of the incision are achieved.

  Further, the program according to the present invention provides an output means for instructing the output of a surgical beam having a function of incising a human tissue, and the surgical beam output by the instruction of the output means to the film-like tissue of the human body. In contrast, control means for controlling at least the direction of irradiation of the surgical beam so as to form an incision from the first surface of the membranous tissue toward the second surface, and the first surface of the incision The computer is caused to function as setting means for setting the cross-sectional shape in a direction intersecting the direction from the first to the second surface to a linear shape other than the linear shape. As a result, by setting the cross-sectional shape to a linear shape other than a linear shape, effects such as suppression of incision stretching when the incision is opened and an instrument is inserted, and ease of self-closing of the incision are achieved. Is done.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram conceptually showing an internal configuration of a laser apparatus 1 as an example of an irradiation apparatus of the present invention. The laser device 1 includes a control unit 2, a laser output unit 3, an optical unit 4, a patient interface 5, an image forming unit 6, an input unit 7, and a display unit 8.

  The control unit 2 is a part that controls the laser device 1. The control unit 2 has a structure similar to that of a normal computer, a CPU that performs various commands and operations related to the present invention, a RAM of a volatile storage unit as a work area of the CPU, and data necessary for various information processing in the CPU. And a non-volatile storage unit 20 (memory) for storing programs. The memory 20 stores a program 21 describing the control procedure of the present invention, various patient data 22 processed by the laser apparatus 1, and the like (details will be described later).

  The laser output unit 3 is a part that outputs a laser for the purpose of incising human tissue, for example. The laser output from the laser output unit 3 may be a femtosecond laser, for example. As is well known, the femtosecond laser is a pulsed laser whose pulse width (or pulse period in the case of periodicity) falls within a range of, for example, 100 femtoseconds to 10 picoseconds. The pulse width, period, etc. of the laser to be output are controlled by the control unit 2.

  The optical unit 4 includes an optical system, that is, a lens, a reflecting mirror, a prism, and the like, and is a part that directs the laser output from the laser output unit 3 to the irradiation target by the action of refraction, reflection, concentration, and divergence of laser light. . The control unit 2 controls the optical unit 4 so that the laser output from the laser output unit 3 is irradiated to a desired position of the irradiation target.

  The patient interface 5 is a part that contacts the patient in the laser apparatus 1. When the patient interface 5 comes into contact with the patient, the positional relationship between the laser apparatus 1 and the patient is fixed, and the laser is stably irradiated to a desired position.

  FIG. 18 shows an embodiment of the patient interface 5. In the example of FIG. 18, the target of laser irradiation is the human eye (such as the cornea 100 or the crystalline lens). In the configuration example of FIG. 18, the patient interface 5 includes a cylindrical portion 50 having a cylindrical shape and a contact glass 51 in contact with the patient's cornea 100. In use, the cylindrical portion 50 is fixed to the patient's eye by bringing the cylindrical portion 50 into contact with the patient's eye so that the cylindrical shape surrounds the surgical site, and sucking the air at the contact portion by the suction portion 9.

  At that time, the contact glass 51 is brought into contact with the cornea 100, so that the positional relationship between the patient interface 5 and the laser device 1 and the patient's eye is also combined with the contact of the contact glass 51 with the cornea 51. It is fixed stably. The contact glass 51 is made of, for example, glass and transmits laser. The contact glass 51 may be a flat applanation glass or may be curved and have a lens function.

  Returning to FIG. 1, the image forming unit 6 acquires a reflected wave formed by reflecting the laser beam output from the laser output unit 3 by an irradiation target (for example, the cornea 100 and the crystalline lens 104), and the reflected wave is obtained. Based on the information such as the delay time, a 3D image of the treatment site and its surroundings is formed.

  The input unit 7 includes various buttons and a numeric keypad, and is a part that receives input from the user related to the present invention. The specific form of the input unit 7 is not limited at all. The content input to the input unit 7 is sent to the control unit 2. The display unit 8 includes a liquid crystal display, for example, and displays information related to the present invention to the user under the control of the control unit 2.

  With the above configuration, the laser device 1 irradiates a laser beam, for example, for incision of human tissue. A laser is output from the laser output unit 3 in response to a command from the control unit 2, and the output laser is subjected to actions such as refraction and reflection by the optical unit 4 under the control of the control unit 2, and passes through the patient interface 5 to human tissue. Is irradiated.

  FIG. 19 is a diagram schematically showing the principle of incision of a human tissue, for example, the cornea 100, by the laser irradiated by the laser device 1. FIG. 19 shows an example in which the laser output from the laser device 1 is a femtosecond laser. As is well known, a femtosecond laser device irradiates a pulsed laser having a pulse width (pulse period) of about 100 femtoseconds to about 10 picoseconds, thereby causing a plasma explosion within an irradiation target to form a cavity. Such cavities are continuously formed in the irradiation object at intervals, and they are connected to form a perforated cut surface. At that time, the depth of the cut surface can be set, and the shallower part is not damaged.

  There are two main purposes of laser irradiation of the laser device 1: surgery (incision) and image formation. When the incision is intended, the irradiated portion is incised by irradiating the incision site of the human tissue with a laser. When image formation is intended, the image forming unit 6 receives the reflected wave of the laser irradiated to the treatment site and its surroundings. As described above, the image forming unit 6 forms a three-dimensional image of the treatment site and its surroundings from information such as a delay time of the reflected wave. The control unit 2 controls (adjusts) the direction and depth of the surgical laser based on the stereoscopic image. The principle of image formation by the image forming unit 6 may be a known optical coherence tomography (OCT), for example.

  Below, the laser irradiation by the laser apparatus 1 shows the case of irradiation with respect to a cornea and a crystalline lens in an eye cataract operation. Normally, during cataract surgery, incision of the cornea, incision of the anterior lens capsule, emulsification and suction treatment of the lens by ultrasound, insertion of an intraocular lens into the eye and placement in the lens capsule, etc. are performed. However, in the laser apparatus 1, it is only necessary to perform incision of the cornea, incision of the anterior lens capsule, and crushing of the lens nucleus.

  FIGS. 2 to 7 show examples of the shape of corneal incision by the laser device 1. FIG. 2 shows an example of the cornea 100 viewed from the visual axis direction and an incision 101 (incision) formed therein. 3 is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 4 is an enlarged view of FIG. 3. The incision 101 is directed from the front surface (surface outside the human body) side to the back surface (surface inside the human body). An example of a cross-sectional shape is shown. In cataract surgery, multiple incisions are performed, including an incision for inserting an intraocular lens and an ultrasonic chip (main incision) and an incision for inserting a hook or the like. An incision may be made.

  In the example of FIGS. 2 to 7, an incision 101 is formed at the position of the side edge of the cornea 100 close to the sclera 102. As shown in FIG. 2, the shape viewed from the surface of the incision 101 is a curved shape, and more specifically, a curved shape that is convex toward the visual axis of the eye (the central axis of the eye). 3 and 4, the cross-sectional shape of the incision 101 including the visual axis is a bent shape or a zigzag shape. More specifically, the incision 101 first proceeds from the corneal surface toward the inside of the eye. 101 a, a portion 101 b bent from there and proceeding substantially parallel to the corneal surface, and a portion 101 c bent from there and reaching the back side of the cornea.

  The position where the portion 101b is formed may be arbitrarily set, for example, a depth position about half the thickness of the cornea 101. Moreover, the cross-sectional shape shown in FIG. 4 of the portions 101a, 101b, and 101c may be a linear shape or a curved shape. The portions 101a and 101b and the portions 101b and 101c may be bent at an acute angle (right angle or obtuse angle) or may be bent smoothly.

  5 to 7 show examples of the BB cross section, the CC cross section, and the DD cross section of the incision 101 in FIG. 4, respectively. In the example of FIG. 5, the cross-sectional shape of the portion 101 a is a curved shape (arc shape) that is convex toward the visual axis side of the eye. In the example of FIG. 6, the curved shape is convex toward the surface side of the cornea 100 continuously from the shape of FIG. 5. In the example of FIG. 7, the curved shape is convex toward the visual axis side of the eye continuously from the shape of FIG. In the incision 101, the cross-sectional shape as shown in FIGS. 5 to 7 may be formed continuously from the front surface side to the back surface side of the cornea 100.

  In the case of the conventional incision, it can be said that the cross-sectional shapes shown in FIGS. 5 to 7 are linear shapes. In that case, for example, when opening an incision for insertion of an intraocular lens or an ultrasonic chip into the eye, there may be a problem that the side end of the incision is torn and the incision is extended.

  On the other hand, in the case of the cross-sectional shape shown in FIGS. 5 to 7, when opening the incision 101, one part (the lower part in FIGS. 5 to 7) of both side parts of the incision 101 is formed. It can be tilted in the direction of the eye, so that an intraocular lens, an ultrasonic chip, etc. can be inserted without any trouble from the gap. Therefore, the conventional incision stretching is effectively suppressed. Further, in the case of the cross-sectional shape as shown in FIGS. 5 to 7, it is considered that the effect of the self-closing of the incision is also improved.

  The cross-sectional shape of the incision in the present invention is not limited to the examples of FIGS. 8 to 10 show a second example of the cross-sectional shape. In the example of FIG. 8, the cross-sectional shape of the portion 101a is a concave curved shape (arc shape) toward the visual axis side of the eye. In the example of FIG. 9, the curved shape is concave toward the surface side of the cornea 100 continuously from the shape of FIG. 8. In the example of FIG. 10, the curved shape is concave toward the visual axis side of the eye continuously from the shape of FIG.

  In the incision 101, the cross-sectional shape as shown in FIGS. 8 to 10 may be formed continuously from the front surface side to the back surface side of the cornea 100. Since the cross-sectional shapes as shown in FIGS. 8 to 10 are not easy even if the shape of the knife is deformed in the case of incision with a knife, the present invention can realize a sectional shape that could not be realized conventionally.

  11 to 13 show a third example of the cross-sectional shape. Specifically, in this example, the portion 101a in FIG. 11 has a circular cross-sectional shape, the portion 101b in FIG. 12 has a linear cross-sectional shape, and the portion 101c in FIG. 13 has a curvature different from that of the portion 101a in FIG. The arc shape has the opposite sign. In the example of FIGS. 11 to 13, the curvature may be set to change continuously (monotonically) as the incision 101 progresses from the front surface side to the back surface side of the cornea 100.

  11 to 13, if the curvature in FIG. 11 is a positive curvature, the curvature is such that the portion 101a is a negative curvature arc, the portion 101b is a straight line, and the portion 101c is a positive curvature arc. May be changed. More generally, as the incision 101 progresses from the front surface side to the back surface side of the cornea 100, the curvature may be set to increase or decrease continuously (monotonically). Furthermore, the present invention is not limited to monotonous increase or monotonic decrease, and the curvature may be set to change (including increase or decrease) according to the progress of incision from the front side to the back side of the cornea. In addition to these examples, in the present invention, the cross-sectional shape of the incision may be set according to the progress of the incision from the front side to the back side of the cornea. As described above, it is considered that determining the cross-sectional shape according to the degree of progress of the incision from the front surface side to the back surface side of the cornea 100 is not easy even if the scalpel shape is deformed in the case of incision with a scalpel. According to the present invention, a cross-sectional shape that could not be realized conventionally can be realized.

  Further, the cross-sectional shape including the visual axis in the incision of the present invention is not limited to the examples of FIGS. FIG. 14 shows a second example of the AA cross section. In this example, the incision is advanced in a cross-sectional (substantially) linear shape from the front side to the back side of the cornea 100. FIG. 15 shows a third example of the AA cross section. In this example, the incision is advanced in a S-shaped cross section from the front side to the back side of the cornea 100. The present invention is not limited to the examples of FIG. 4, FIG. 14, FIG.

  The present invention is not limited to the cross-sectional shapes shown in FIGS. 5 to 13, but may be cross-sectional shapes as shown in FIGS. 16 and 17, for example. In the example of FIG. 16, the cross-sectional shape of the incision 101 is V-shaped (or inverted V-shaped). In the example of FIG. 17, the cross-sectional shape of the incision 101 is a wave shape. In the case of FIGS. 16 and 17, either the upper side or the lower side in the figure may be the sclera side.

  In any of the cross-sectional shapes of the incision, when an object is inserted from the outside of the eye into the eye through the incision, the convex shape that collapses from the surface side of the cornea to the back side is formed on both sides of the incision. It is formed in at least one of them. (For example, in the case of FIGS. 5 to 7, the lower side of the incision 101 is convex in the upper and lower sides of the incision 101. In FIGS. 8 to 10, the upper side of the incision 101 is the convex shape.) Depending on the shape, it may be possible to suppress the extension of the incision at the time of inserting an object and to improve the self-closing ability of the incision.

  An example of the processing procedure of the laser apparatus 1 for making the above incision is shown in FIG. The processing procedure of FIG. 20 is programmed in advance and stored in the memory 20 as the program 21, and the control unit 2 may call it and automatically execute processing other than processing manually performed by the user.

  In the processing procedure of FIG. 20, first, in S10, the relative positional relationship between the laser device 1 and the treatment site of the patient is fixed. Specifically, as described above, the laser device 1 may be fixed to the patient's eye by the patient interface 5 as shown in FIG.

  Next, the control unit 2 calls the patient data 22 from the memory 2 in S20. The patient data 22 may be various data of a patient to be treated by the laser device 1, for example, data such as past treatment locations, and may be stored in past treatment opportunities. In S20, the called patient data may be displayed on the display unit 8. For example, the user may refer to the information in the input in S50 described later. In addition, embodiment which abbreviate | omitted the procedure of patient data 22 and S20 may be sufficient.

  Next, at 30, the control unit 2 instructs the laser output unit 3 to output an image forming laser. In response to this, the laser output unit 3 radiates the output of the image forming laser toward the treatment site and its periphery. In S <b> 40, the image forming unit 6 receives the reflected laser wave reflected by the treatment site, thereby forming an image (for example, a three-dimensional image) of the treatment site and its periphery. The control unit 2 may acquire the image and display it on the display unit 8.

  In step S50, the user inputs the incision position, shape, and the like using the input unit 7. Specifically, for example, a cross-sectional shape related to the cross section including the visual axis of the incision (for example, the shape shown in the AA cross section in FIGS. 4, 14, and 15 in the above example) is first input, and then the cross-sectional shape If you specify a desired point above and input the cross-sectional shape of the incision at the position of the point (however, the cross-section is the cross-section in the direction that the incision proceeds from the front to the back of the cornea) Good.

  There may be several forms as an input method using the input unit 7. For example, the position of each point on the cut surface may be input numerically. In this case, for example, when the cross-sectional shape of the incision is set in an arc shape as shown in FIGS. 6 to 10 and the like, the curvature of the arc may be numerically input. Or you may designate the position of each point of an incision surface with a pen on the image of the treatment site | part displayed on the display part 8 by using the display part 8 as a touch panel.

  Alternatively, some typical incision shapes may be described in advance in the program 21, and the user may select a desired shape from them. Furthermore, it may be displayed in a superimposed manner on the image of the treatment site, and the user may finely correct it with a pen or numerical input. In any of the input forms, in order to allow the user to confirm whether or not the input content by the user is appropriate, the incision shape set by the user input is formed in the image of the surgical site and its surroundings (formed in S40). The image may be displayed on the display unit 8 in a superimposed manner.

  Next, in S60, the control unit 2 instructs the laser output unit 3 to output the surgical laser so as to form the incision having the shape set in S50. Thus, an incision is formed in the patient's cornea according to the principle shown in FIG. The above is the processing procedure of FIG.

  The processing procedure in FIG. 20 is merely an example and may be changed as appropriate. For example, the process of S50 may be performed prior to the process of FIG. In that case, specifically, for example, the data of the shape of the patient's cornea in the past examination is acquired (by executing S30, S40, etc.), and the process of S50 is executed on the data. Good. The patient's cornea shape data and incision shape data are included in the patient data 22 and stored in the memory 2, and may be recalled in S 20.

  The processing procedure of FIG. 20 is incorporated as part of the overall cataract surgery. An example of the procedure other than the processing of FIG. 20 is as follows. Prior to (or subsequent to) the processing of FIG. 20, the anterior lens capsule is cut using the laser device 1. In this incision, for example, a circular incision 105 around the visual axis may be formed in the anterior lens capsule.

  Following this, the nucleus of the crystalline lens 104 that has become cloudy due to cataracts is crushed by the laser of the laser device 1. Then, the nucleus of the crushed lens 104 is sucked using a predetermined ultrasonic emulsification suction device (not shown). At that time, for example, the ultrasonic chip of the same apparatus is inserted into the eye through the incision 101 and further inserted into the crystalline lens through the incision 105 to perform a suction process. In this case, most of the nuclei may be crushed by the laser device 1 and the remaining portion may be crushed and sucked by the ultrasonic emulsification suction device.

  Subsequently, the intraocular lens 107 is inserted into a state in which the inside of the crystalline lens 104 becomes a cavity and the posterior capsule 106 remains. An example of this state is shown in FIG. In this example, the intraocular lens 107 includes a lens 107a and a haptic 107b. The haptic 107b is formed in a tactile shape (haptic shape, loop shape) from, for example, two places on the side edge of the lens 107a, and has appropriate elasticity. It is assumed that the lens 107a also has elasticity.

  When the intraocular lens is mounted, for example, the intraocular lens 107 that has been rounded into a bar shape is accommodated in an instrument (not shown) such as a predetermined cartridge. Then, the distal end of the instrument is inserted into the eye through the incision 101, for example, and further inserted into the posterior capsule 106 beyond the iris 103, and the intraocular lens 107 is delivered from the distal end of the instrument in this state. As a result, the intraocular lens 107 is inserted into the posterior capsule 106, and the haptic 107b always presses the interior of the posterior capsule 106 by the elastic restoring force. Thus, the intraocular lens 107 is stably fixed in the posterior capsule 106. The above is an example of a surgical procedure in cataract surgery.

  The above-described embodiments may be modified and modified based on the spirit described in the claims. For example, in the above embodiment, the laser device is exemplified as the irradiation device. However, the present invention is not limited to this, and any device that outputs an (optical) beam having a cutting ability of human tissue may be used. Moreover, although the example of the corneal incision in a cataract was described above, this invention is not limited to it, For example, incision of other membranous tissues, such as a sclera, may be sufficient, and surgery other than a cataract may be sufficient. Furthermore, the present invention is not limited to the eyes, and may be an incision of human tissue or an incision of, for example, a film-like part of human tissue.
