  The best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described below with reference to the drawings.

  First, a first embodiment will be described with reference to FIGS.

  As shown in FIG. 1, an image observation system 10 according to this embodiment includes an image observation apparatus (not shown) such as a microscope or an endoscope (rigid endoscope) used for observing a surgical site, and an operator. And an image display device for displaying an image observed by the image observation device in real time or the like.

  The pedestal 12 includes a base 22 placed on the floor and a chair 24 disposed on the base 22 and on which an operator sits. A plurality of casters 22 a are attached to the base 22. For this reason, the chair 24 can be arranged in a desired direction at a desired position by moving the base 22 relative to the operating table 16 (contacting / separating). In other words, the chair 24 can be moved toward and away from the patient's surgical part 18 placed on the operating table 16.

  The chair 24 includes a leg body 26 fixed to the base 22, a seat portion 28 disposed on the leg body 26, and a backrest 30 connected to or integrally formed with the seat portion 28. . An arm 32 is disposed at the upper end of the backrest 30. Specifically, the lower end of the arm 32 is supported on the upper end of the backrest 30. An image projection unit (projector) 34 which is a part of the image display device is attached to the upper end portion of the arm 32. In other words, an image projection unit 34 that projects an image obtained by an image observation apparatus (not shown) such as a microscope onto an image display unit 36 (described later) is disposed at the upper end of the backrest 30 by the arm 32.

  An image display unit 36 that is a part of an image display device that displays an image projected by the image projection unit 34 is provided at the tip of a support bar 42 supported by a holding unit 38 provided on the left side of the pedestal 12, for example. Is retained. As shown in FIG. 2, such holding portions 38 are respectively disposed on the left side and the right side of the base 12. Hereinafter, the holding portion that does not specify the left side and the right side is mainly denoted by reference numeral 38 as described above, the left holding portion is denoted by reference numeral 38L, and the right holding portion is denoted by reference numeral 38R. To do. The left holding portion 38L and the right holding portion 38R are arranged symmetrically with respect to the alternate long and short dash line indicated by reference sign SS in FIGS. 1 and 2.

  As shown in FIG. 3, these holding portions 38 include a holding portion main body 45, an insertion portion 46, a circular hole (not shown), and a screwed portion (rotating knob) 48. The holding unit main body 45 is attached to the base 22 of the base 12. The insertion portion 46 is formed in the holding portion main body 45, and a base end portion of a support rod 42 described later is inserted therein. The insertion portion 46 is formed, for example, in a cylindrical shape, and its longitudinal axis is inclined forward of the chair 24 with respect to the vertical direction. A circular hole has an axis | shaft in the direction orthogonal to the longitudinal axis of the insertion part 46, and has an internal thread in an edge part. The screwed portion (rotating knob) 48 has a male screw that is screwed into the circular hole.

  As shown in FIG. 4, the support rod 42 is integrally formed with the base end portion being straightly extended and the tip end being curved in a substantially semicircular shape. At the base end portion of the support rod 42, a cut portion 44 in which a screwed portion 48 described later is disposed is formed. On the other hand, an image display unit 36 is attached to the tip of the support bar 42. The image display unit 36 is formed of a sterilizable material such as a stainless material. Further, the support rod 42 is formed of a sterilizable material such as a stainless material.

  For example, a pair of flanges 52 facing each other are formed at the tip of the support bar 42. On the other hand, the image display unit 36 attached to the support rod 42 includes, for example, a screen unit 56 and a support mechanism 58 integrally. The support mechanism 58 includes a coupling portion 62 that covers the flange 52 at the tip of the support rod 42, and a hole portion 64 that is provided in the coupling portion 62 corresponding to the flange 52 of the support rod 42 and has a female screw. . A rotation knob 66 having a male screw can be screwed into the hole 64. For this reason, the tip of the rotary knob 66 is disposed between the flanges 52 of the support bar 42, and the support bar 42 and the image display unit 36 are fixed.

  Since the left holding portion 38L and the right holding portion 38R are attached symmetrically, as shown in FIG. 5, the support bar 42 is not only provided on the left holding portion 38L of the chair 24 but also on the right side. It is similarly held in the holding portion 38R. That is, the support bar 42 can be selectively supported by the left and right holding portions 38L and 38R of the chair 24. Then, it can be appropriately selected depending on the operator's dominant arm, the standing position of the assistant, and the like.

  Next, the operation of the image observation system 10 according to this embodiment will be described.

  The image display unit 36 is attached to the sterilized support rod 42. In this case, the flange 52 at the tip of the support rod 42 is covered with the coupling portion 62 of the image display portion 36. The rotation knob 66 is screwed into the hole 64 of the coupling portion 62 and the tip of the rotation knob 66 is disposed between the flanges 52 to fix the support rod 42 and the image display portion 36.

  The base end portion of the support rod 42 in this state is attached to the holding portion 38L on the left side of the base 22 (chair 24). In this case, the base end portion of the support rod 42 is inserted into the insertion portion 46 of the holding portion 38. The support rod 42 is rotated around its axis, and the screw portion 48 is screwed into the cut portion 44 of the support rod 42. Then, the image display part 36 at the tip of the support bar 42 is arranged at a desired position in front of the operator. In this state, the position of the image display unit 36 is adjusted so as to be arranged at a desired position with respect to the operator.

  For example, there is a case where the standing position of the assistant is changed from the left side to the right side when viewed from the back of the chair 24 during the treatment of the surgical part 18. In this case, the assistant loosens the screwed portion 48 of the left holding portion 38L while holding the position of the support rod 42 close to the chair 24 (base end side). Then, the fixing of the support bar 42 to the left holding portion 38L is released, and the support bar 42 is pulled out in the direction of the arrow X in FIG.

  As shown in FIG. 5, the assistant who pulled out the support bar 42 moves to the right side of the chair 24 and inserts the base end part of the support bar 42 into the insertion part 46 of the right holding part 38R. When the assistant screwes the screw portion 48 in a state where the screw portion 48 of the right holding portion 38R is fitted to the notch portion 44 of the support rod 42, the support rod 42 is fixed to the chair 24. The image display unit 36 is disposed at a spatial position that is aligned with the right side when viewed from the back of the chair 24 at the tip of the support bar 42.

  As described above, according to this embodiment, the following can be said.

  By simply attaching and detaching the support bar 42 to and from the holding unit 38, the image display unit 36 can be disposed at a desired position that is unlikely to be an obstacle to the operator or can be retracted. That is, it is possible to provide the image observation system 10 that can easily retract the image display unit 36 when the image display unit 36 is not used.

  When the support bar 42 is removed, the base 12 can be used simply as a chair. Therefore, the image observation system 10 can be accommodated as long as the chair 24 has an occupied area. That is, the storage space of the image observation system 10 can be reduced. Further, the support rod 42 can be sterilized and can be reused, which is efficient and can reduce the cost.

  Further, if the image display unit 36 is configured with a light screen, the amount of moment applied to the support bar 42 can be reduced, and therefore, the support bar 42 is not high in strength but can be used with an appropriate strength. it can.

  Next, a second embodiment will be described with reference to FIGS. This embodiment is a modification of the first embodiment. The same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 6, the holding portion 38 that holds the base end portion of the support bar 42 is provided not only on the left and right sides of the chair 24 but also on the back surface of the backrest 30 of the chair 24. The holding portion provided on the back surface of the backrest 30 will be described with reference numeral 38B.

  As with the left and right holding portions 38L and 38R described in the first embodiment, the holding portion 38B provided on the back surface of the backrest 30 has a holding portion main body 45, an insertion portion 46, and a circular hole ( (Not shown) and a screwed portion (rotating knob) 48.

  As shown in FIG. 7, the insertion portion edge (opening portion edge portion) of the insertion portion 46 of the holding portion 38 when the support rod 42 is inserted into the holding portion 38 around the flange 52 and the coupling portion 62 of the support rod 42. ) Is arranged on a locus L indicated by a broken line in FIG. That is, when the insertion portion edge portion of the holding portion 38 is disposed on the locus L, the flange 52 and the coupling portion 62 of the support rod 42 are positioned at predetermined positions. In this embodiment, the insertion portion edges of the insertion portions 46 of the left holding portion 38L, the right holding portion 38R, and the holding portion 38B provided on the back surface of the backrest 30 are on the locus L.

  Further, the image display unit 36 is rotatable with the coupling unit 62 of the support mechanism 58 as a fulcrum. The image display unit 36 rotates in a state in which the rotation knob 66 is sandwiched between the flange 52 at the tip end portion of the support rod 42. At this time, the support mechanism 58 is the center of rotation and remains in that position. For this reason, when the base end portion of the support bar 42 is arranged on the locus L, the image display unit 36 is always arranged at the same position, so that the operator can use the same regardless of the position of the support bar 42. The screen unit 56 of the image display unit 36 can be observed at the position.

  Next, the operation of the image observation system 10 according to this embodiment will be described.

  As described in the first embodiment, for example, the support bar 42 is attached to the left holding portion 38L and the right holding portion 38R. From this state, the support bar 42 is disposed on the holding portion 38B on the back surface of the backrest 30. That is, the arrangement position of the support bar 42 is switched. In a state where the support bar 42 is simply disposed on the holding portion 38B, the image display portion 36 is at a position indicated by a broken line in FIG. In this case, the image of the image projection unit 34 cannot be displayed on the screen unit 56 of the image display unit 36.

  An operator or an assistant in the clean area loosens the rotation knob 66 of the support mechanism 58 and rotates the image display unit 36 in the direction of arrow R1 in FIG. 6, and then rotates the rotation knob 66 in the reverse direction to move the image display unit 36. Fix it.

  Then, the insertion portion edge of the holding portion 38B is on a locus L indicated by a broken line in FIG. 7, and the locus L is centered on the coupling portion 62 of the support mechanism 58 in FIG. The mechanism 58 is always located at the same position. Therefore, the surgeon can place the image display unit 36 at the same position as when the support bar 42 is held by the left holding unit 38L or the right holding unit 38R as shown in FIGS. The observation can be performed at that position.

  As described above, according to this embodiment, the following can be said.

  One support bar 42 can be selectively attached to the chair 24 at positions on the left side, right side, and back side (upper side). Since the assistant can be located on either the left or right side of the chair 24, the standing position can be changed even when the treatment position of the surgical site is changed.

  Next, a third embodiment will be described with reference to FIGS. This embodiment is a modification of the first embodiment. The same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 8, the image observation system 10 according to this embodiment detects whether or not the support bar 42 is arranged in the insertion part 46 of the holding part 38, and the support bar 42 is inserted in the insertion part 46. , The rotation position of the support bar 42 is detected, and the power of the image projection unit 34 is automatically switched on / off.

  First and second switches 72 and 74 are disposed in the insertion portion 46 of each holding portion 38. The first switch (SW1) 72 is provided at the bottom of the insertion portion 46 and detects whether or not the proximal end portion of the support bar 42 is inserted into the insertion portion 46 of the holding portion 38. The second switch (SW2) 74 is provided on the side portion of the insertion portion 46, and the base end portion of the support rod 42 is disposed on the insertion portion 46 of the holding portion 38, and the second switch (SW2) 74 The rotation position is detected. As shown in FIG. 9, a protrusion 76 is formed on the base end portion of the support rod 42. The protrusion 76 can be switched between a position where the second switch 74 is pressed (ON position) and a position where the pressure is released (OFF position) by turning the support rod 42 around the axis.

  Furthermore, as shown in FIG. 10, the first and second switches 72 and 74 are electrically connected to the switch detection unit 80, respectively. The switch detection unit 80 is electrically connected to the projection unit control unit 82. The projection unit control unit 82 is electrically connected to the projection unit power supply unit 84. The projection unit power supply unit 84 is electrically connected to the image projection unit 34. The image projection unit 34 is electrically connected to a surgical microscope (image observation device) 86 for obtaining an observation image of the surgical unit 18 (see FIG. 1), for example.

  Note that the switch detection unit 80 and the projection unit control unit 82 are respectively disposed inside the base 22 of the base 12 in order to use space effectively. The projection unit power supply unit 84 is provided in the image projection unit 34.

  Next, the operation of the image observation system 10 according to this embodiment will be described.

  The surgeon performs various observations in a state where the image display unit 36 is disposed at a position indicated by a broken line in FIG. When the surgeon directly observes the surgical site, the image display unit 36 is rotated in the direction of arrow R2 and moved to the position indicated by the solid line in FIG. Specifically, an assistant or the like loosens the screwed portion 48 and rotates the support bar 42 around the axis of the support bar 42. In this case, the surgeon and assistant rotate the support bar 42 until the image display unit 36 is disposed at the position shown in FIG. 11, for example.

  Then, the second switch 74 is pushed by the protrusion 76 of the support bar 42 by the rotation of the support bar 42. When the second switch 74 is pushed, the switch detection unit 80 detects that the second switch 74 is pushed.

  On the other hand, even when the support bar 42 is rotated around its axis, the first switch 72 is in a pressed state. For this reason, the switch detection unit 80 detects that the first switch 72 is pushed.

  The switch detection unit 80 transmits a signal indicating that the second switch 74 is pressed in a state where the first switch 72 is pressed into the projection unit control unit 82. The projection control unit 82 switches the power of the projection unit power supply unit 84 to OFF. That is, the projection of the image is stopped from the image projection unit 34 that projects the image obtained by the surgical microscope 86. For this reason, it is possible to prevent the image projected from the image projection unit 34 from being projected onto a part in the operating room other than the image display unit 36 (for example, an operation site).

  When performing image observation again, the surgeon returns the image display unit 36 to the position indicated by the broken line in FIG. Specifically, the screwing portion 48 of the holding portion 38 is rotated to release the support rod 42 from being fixed. In this state, the operator or the like rotates the image display unit 36 in the direction opposite to the direction of the arrow R2 in FIG. An assistant or the like rotates the rotary knob 66 to fix the support rod 42.

  At this time, the first switch 72 is in an ON state, and the second switch 74 is in an OFF state. This state is detected by the switch detection unit 80 and transmitted to the projection unit control unit 82. The projection unit control unit 82 switches the power of the projection unit power supply unit 84 to the ON state. The image projection unit 34 causes the image display unit 36 to display an image obtained by the surgical microscope 86.

  When both the first and second switches 72 and 74 are in the OFF state, the image projection unit 34 is prevented from projecting an image.

  As described above, according to this embodiment, the following can be said.

  For example, in the case of direct observation without observing an image such as a microscope using the image display unit 36, it is possible to prevent the observation image light emitted from the image projection unit 34 from being irradiated to an appropriate part in the operating room. The surgeon can observe as desired without projecting extra light.

  Moreover, ON / OFF of the image projection part 34 can be controlled automatically.

  In this embodiment, it has been described that the power of the image projection unit 34 is switched ON / OFF. For example, a shutter is provided in the image projection unit 34, the first switch 72 is ON, and the first switch 74 is OFF. If the shutter is opened while the first switch 72 is ON and the second switch 74 is ON while the shutter is closed, it is possible to eliminate the need to consider the activation time of the image projection unit 34. Even when such a shutter is provided in the image projection unit 34, the power of the image projection unit 34 may be turned off when the first switch 72 is OFF.

  Next, a fourth embodiment will be described with reference to FIGS. This embodiment is a modification of the first embodiment. The same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the image observation system 10 according to this embodiment, a cylindrical electromagnet 92 is provided in the insertion portion 46 of the holding portion 38 that holds the support rod 42, and the support rod 42 is held by the holding portion 38 by electromagnetic force. . As shown in FIG. 12, an electromagnet 92 is disposed on the peripheral edge of the insertion portion 46 of the holding portion 38. A switch (SW) 94 for switching the excitation of the electromagnet 92 to ON / OFF is disposed on the base 22 of the base 12.

  As shown in FIG. 13, the electromagnet 92 is electrically connected to an electromagnet power source 96. The electromagnet power supply 96 is electrically connected to the switch 94. Although not shown here, the electromagnet power supply 96 is further provided with a main switch. When the main switch is ON, the electromagnet 92 is excited.

  As shown in FIG. 14, a magnet 42 a is attached to the base end portion of the support rod 42.

  Next, the operation of the image observation system 10 according to this embodiment will be described.

  The surgeon presses a switch 94 provided on the base 22 of the base 12. A signal is transmitted from the switch 94 to the electromagnet power supply 96 to turn off the power supply 96 of the electromagnet 92. The electromagnet 92 is de-energized by the electromagnet power supply 96, and the electromagnet 92 of the insertion portion 46 of the holding portion 38 and the magnet 42a of the support bar 42 are not coupled by magnetic force.

  An assistant or the like holds the support rod 42 and inserts the support rod 42 into the insertion portion 46, and the operator places the image display portion 36 at a position indicated by a broken line in FIG. 11.

  The surgeon releases the pressing of the switch 94 provided on the base 22 of the base 12. A signal is transmitted from the switch 94 to the electromagnet power supply 96 to turn on the power supply 96 of the electromagnet 92 of the insertion portion 46 of the holding portion 38. The electromagnet 92 of the insertion portion 46 of the holding portion 38 is excited to couple the electromagnet 92 of the insertion portion 46 of the holding portion 38 and the magnet 42a of the support rod 42 by magnetic force.

  In this state, the surgeon looks at the image display part 36 and observes the surgical part.

  When the surgeon observes the surgical site directly, the surgeon presses a switch 94 provided on the base 22 of the base 12. A signal is transmitted from the switch 94 to the electromagnet power source 96 to turn on the electromagnet 92 of the insertion portion 46 of the holding portion 38.

  The electromagnet 92 of the insertion portion 46 of the holding portion 38 is excited by the electromagnet power source 96, and the coupling by the magnetic force between the electromagnet 92 of the insertion portion 46 of the holding portion 38 and the magnet 42a of the support rod 42 is released.

  The surgeon releases the pressing of the switch 94 and fixes the support rod 42 in a state where the image display unit 36 is moved to the position indicated by the solid line in FIG. Then, the surgical site is observed directly with the image display unit 36 retracted.

  As described above, according to this embodiment, the following can be said.

  Only by operating the switch 94 provided on the base 22 of the pedestal 12, the image display unit 36 can be disposed in the vicinity of the surgical site and retracted outside the surgical site. This eliminates the need for an assistant or the like as in the third embodiment, so that the image display unit 36 can be arranged smoothly, and thus the operation can proceed smoothly.

  Note that the image display unit 36 according to the first to fourth embodiments may be a screen as described above, or may be a lightweight LCD, an organic EL display, or the like. When using an LCD or an organic EL display, the image projection unit 34 is not necessary.
