All of these components (including parts such as the fastening screws used) that make up the medical support and fixation device 2 reliably avoid the occurrence of failures during radiotherapy, imaging, nuclear magnetic resonance imaging, etc. Therefore, it is preferable that it be made of synthetic resin rather than metal.

Continuing the explanation with reference to FIGS. 4 to 6, the base plate 4 has a rectangular shape, with one end (the left end in FIGS. 4 to 6) and the center in the width direction (vertical direction in FIGS. 4 and 5) A circular hole is formed in the circular hole, and a bearing member 14 is fixed to this circular hole by press fitting. A short shaft member 16 that passes through this bearing member 14 is fixed to the base plate 4 (fixing of the short shaft member 16 will be further referred to later). The short shaft member 16 extends perpendicularly to the base plate 4, and an annular flange is formed at the upper end of the short shaft member 16. Various parts (these parts will be described later) constituting the yaw angle fine adjustment mechanism 10 are arranged at the other end of the base plate 4 (the right end in FIGS. 4 to 6). A backing material 18 whose dimensions are somewhat smaller than that of the base plate 4 is adhered to the back surface (lower surface in FIG. 6) of the base plate 4. The backing material 18, which is advantageously formed from a soft synthetic resin, is provided in the region where the short shaft member 16 and the components of the yaw angle adjustment mechanism 10 are present, as clearly illustrated in FIG. It is cut out in the area where it is done.

As clearly understood from FIGS. 7 to 9, the yaw angle fine adjustment plate 6 also has a rectangular shape, and its one end (the left end in FIGS. 7 to 9) and the width direction (the vertical direction in FIGS. 7 and 8) ) A circular hole is formed in the center, and a short cylindrical bearing member 20 is fixed to this circular hole by press fitting. On the back surface (lower surface in FIG. 9) of the other end of the yaw angle fine adjustment plate 6, parts (these parts will be described later) constituting the yaw angle fine adjustment mechanism 10 are arranged.

By fixing to the base plate 4 the short shaft member 16 that passes through the bearing member 20 fixed to the other end of the plate 6 and the bearing member 14 fixed to the other end of the base plate 4, the base plate 4 The upper yaw angle fine adjustment plate 6 is rotatably mounted around the central axis 26 of the short shaft member 16. In the illustrated embodiment, the short shaft member 16 is fixed to the base plate 4 by disposing a circular retaining piece 28 on the back surface of the base plate 4, the outer diameter of which may be the same as the outer diameter of the flange of the short shaft member 16. This is realized by screwing the fastening screw 30 onto the short shaft member 16 through the circular stopper 28. In the illustrated embodiment, the short shaft member 16 is fixed to the base plate 4 and the bearing member 20 is fixed to the yaw angle fine adjustment plate 6, but the bearing member 20 is fixed to the base plate 4 and the yaw angle fine adjustment plate It is also possible to fix the short shaft member 16 to 6. Alternatively, the bearing member 20 may be omitted and the circular hole formed in the yaw angle fine adjustment plate 6 (or base plate 4) may be used as a bearing hole, and the short shaft member 16 may be assembled (i.e., inserted) into this bearing hole. You can also do that.

A tilt angle fine adjustment plate 8 is illustrated in FIGS. 10 to 12. The tilt angle fine adjustment plate 8 has a rectangular main portion 32 and drooping portions 34 that hang down from both side edges of the main portion 32 . One end of the tilt angle fine adjustment plate 8 (the left end in FIGS. 10 to 12) is connected to one end of the yaw angle fine adjustment plate 6 via at least one hinge 36 so as to be freely pivotable. Specifically, in the illustrated embodiment, two hinges 36 are arranged at intervals in the width direction (vertical direction in FIGS. 7 to 12) of the yaw angle fine adjustment plate 6 and the tilt angle fine adjustment plate 8. The pivot axis 37 of the hinge 36 extends in the width direction of the yaw angle fine adjustment plate 6 and the tilt angle fine adjustment plate 8. As shown in FIGS. 10 to 12, the one-side rotating part 38 located at the center of the hinge 36 is fixed to the back surface of one side of the tilt angle fine adjustment plate 8 by a fastening screw 40, and is located on both sides of the hinge 36. The other side rotating portion 42 is fixed to the surface of one side of the yaw angle fine adjustment plate 6 by a fastening screw 44. A pair of tilt angle indicator pieces 46 are fixed to the lower surface of the other end of the tilt angle fine adjustment plate 8 at intervals in the width direction of the tilt angle fine adjustment plate 8 by fastening screws 47 . The tip of the tilt angle indicator piece 46 protrudes beyond the other edge of the tilt angle fine adjustment plate 8. A pair of protrusions 48 are fixed to the surface of the other end of the tilt angle fine adjustment plate 8 at intervals in the width direction of the tilt angle fine adjustment plate 8. A pair of circular holes are formed at intervals, and the bearing member 50 is press-fitted into the circular holes. The pair of protrusions 48 and the pair of bearing members 50 are used to mount a fixing means (an example of which is shown by a two-dot chain line in FIG. 1) for fixing a predetermined part of the human body on the tilt angle fine adjustment plate 8. I can do it.

Next, the yaw angle fine adjustment mechanism 10 will be described with reference to FIG. 13 as well as FIGS. 1 to 9. A support member 52 extending long and narrow in the width direction of the base plate 4 is fixed to the surface of the other end of the base plate 4 by a fastening screw 54 (FIG. 5). A circular hole 56 is formed in the center of the support member 52, and a bearing member 58 is fixed on the surface of the center of the support member 52 with a fastening screw (not shown). A circular hole 60 is formed in the bearing member 58, which is concentric with the circular hole 56 formed in the support member 52, and has a lower portion with a relatively large diameter and an upper portion with a relatively small diameter. An input member 62 is rotatably mounted on the bearing member 58. The input member 62 has a fitting part 62a having an outer diameter corresponding to the inner diameter of the upper part of the circular hole 60 of the bearing member 58, and a grip part 62b having an outer diameter larger than the outer diameter of the fitting part 62a. The input member 62 is rotatably attached to the bearing member 58 by fitting the portion 62a into the circular hole 56 of the bearing member 58. A transmission gear 64 is fixed to the lower end surface of the input member 62. The through hole 66 formed in the center of the transmission gear 64 has an upper part with a relatively small diameter and a lower part with a relatively large diameter, and has a head having an outer diameter larger than the upper part and smaller in diameter than the lower part. The transmission gear 64 is fixed to the input member 62 by screwing the fastening screw 68 having the input member 62 through the through hole 66 of the transmission gear 64. The relative angular position of the transmission gear 64 with respect to the input member 62 can be regulated by a regulation pin 70 interposed between the two. In the illustrated embodiment, the input member 62 and the transmission gear 64 are formed separately and fixed together by a fastening screw 68, but they can also be formed integrally if desired. On the other hand, an arcuate gear piece 72 is fixed to the back surface of the other end of the yaw angle fine adjustment plate 6 by a set screw 74, and this arcuate gear piece 72 is engaged with the transmission gear 64. As will be clearly understood by referring to FIG. 5, an opening 76 is formed at the other end of the base plate 4 to correspond to the transmission gear 64 and the arcuate gear piece 72. As shown in FIGS. 1, 2, and 4, a sheet 78 on which a yaw angle memory is printed is adhered to the surface of the support member 52.

In the yaw angle fine adjustment mechanism 10 as described above, when the grip portion 62b of the input member 62 is gripped and rotated, the rotation is transmitted to the arcuate gear piece 72 via the transmission gear 64, and the rotation is transmitted to the arcuate gear piece 72 as shown in FIG. As shown at 6A and 6B, the yaw angle fine adjustment plate 6 is rotated about the central axis 26 of the short shaft member 16 with respect to the base plate 4, and the yaw angle of the yaw angle fine adjustment plate 6 with respect to the base plate 4 is adjusted. fine-tuned. By referring to the position of the yaw angle indicator piece 22 relative to the yaw angle memory printed on the sheet 78, the yaw angle of the yaw angle fine adjustment plate 6 relative to the base plate 4 can be visually confirmed. The above-mentioned support member 52 extends beyond the other edge of the base plate 4, and a circular hole 80 and an oblong hole 82 are formed at the extending end. The circular hole 80 and the oblong hole 82 can be used to mount a fixing means (an example of which is shown by a two-dot chain line in FIG. 1) for fixing a predetermined part of the human body on the tilt angle fine adjustment plate 8. can.

Next, the tilt angle fine adjustment mechanism 12 will be explained with reference to FIG. 14 as well as FIGS. 1 to 3 and 7 to 12. As clearly understood by referring to FIG. 1, a pair of guide walls 84 are provided on the surface of the other end of the yaw angle fine adjustment plate 6 at intervals in the width direction. More specifically, each of the guide walls 84 stands perpendicularly to the yaw angle fine adjustment plate 6, and extends parallel to each other. Each of the guide walls 84 is attached to the surface of the yaw angle fine adjustment plate 6 by screwing a plurality of fastening screws (not shown) into the lower end of each of the guide walls 84 from the back side of the yaw angle fine adjustment plate 6. Fixed. One side of the inner surface (surfaces facing each other) of each of the guide walls 84 is relatively thick and the other side is relatively thin, and there is a space between the two that extends perpendicularly to the surface of the yaw angle fine adjustment plate 6. A shoulder surface 86 (FIG. 1 shows the shoulder surface 86 formed on one inner surface of the guide wall 84) facing one end side (lower left side in FIG. 1) is formed. A sheet 88 (one of the sheets 88 is shown in FIG. 1) on which a tilt angle memory is printed is attached to the outer surface of each guide wall 84. A bearing member 90 is fixed between the upper end surfaces of the pair of guide walls 84 with fastening screws 92 . A bearing hole 94 (FIG. 14) is formed in the center of the bearing member 90 in the width direction. Each of the above-mentioned tilt angle indicating pieces 46 protrudes beyond the other edge of the tilt angle fine adjustment plate 8 and is located close to the outer surface of the pair of guide walls 84.

As clearly shown in FIG. 14, a circular opening 100 is formed at the center in the width direction of the other end of the yaw angle fine adjustment plate 6, and a bearing member 102 is press-fitted into this circular opening 100. The main portion of the bearing member 102 has a short cylindrical shape, and an annular flange is attached to the upper end. A male screw member 104 is rotatably attached to the bearing member 102 fixed to the bearing member 90 and the yaw angle fine adjustment plate 6. The outer diameters of the upper end 104a and lower end 104b of the male threaded member 104 are somewhat smaller than the outer diameter of the main portion 104c, and their outer peripheral surfaces are cylindrical, with the upper end 104a being fitted into the bearing hole 94 and the lower end 104b is fitted into the bearing member 102, and the male threaded member 104 is thus rotatably mounted. A male thread is formed on the outer peripheral surface of the main portion 104c of the male threaded member 104. As clearly shown in FIGS. 1 and 14, a female threaded member 106 is screwed onto the male threaded member 104. A locking piece 108 extending downward from the other end of the tilt angle fine adjustment plate 8 is attached to this female screw member 106 . In the illustrated embodiment, the locking piece 108 is elongated in the width direction of the yaw angle fine adjustment plate 6, and the length in the width direction on one side thereof is somewhat smaller than the length in the width direction on the other side. Shoulder surfaces 110 facing the other end (upper right side in FIG. 1) are formed on both sides of the locking piece 108. As clearly understood by referring to FIG. 1, the shoulder surfaces 110 formed on both sides of the locking piece 108 abut against the shoulder surfaces 86 formed on the inner surfaces of each of the pair of guide walls 84. The locking pieces 108 are brought close to each other, and the vertical movement of the locking pieces 108 is guided by the pair of guide walls 84. In the illustrated embodiment, the female thread member 106 and the locking piece 108 are integrally formed, but if desired, they can be formed separately and fixed to each other by appropriate means. An input member 112 whose upper part has a short cylindrical shape is fixed to the upper end of the male screw member 104 by a fastening screw 114 . A through hole 116 is formed in the male threaded member 104 and has a relatively large inner diameter at the lower part and a relatively small inner diameter at the upper part, and the shaft of the fastening screw 114 passes through the upper part of the through hole 116 and is screwed into the input member 112 ing. If desired, input member 112 can be integrally formed with externally threaded member 104.

In the tilt angle fine adjustment mechanism 12 as described above, when the input member 112 is gripped and rotated in a predetermined direction (for example, clockwise when viewed from above), the female threaded member 106 is raised and the locking piece 108 adjusts the tilt angle finely. The other end of the tilt angle fine adjustment plate 8 is raised by coming into contact with the back surface of the other end of the adjustment plate 8, and thus the tilt angle of the tilt angle fine adjustment plate 8 is increased as shown by the two-dot chain line in FIG. Ru. When the input member 112 is rotated in the opposite direction (for example, counterclockwise when viewed from above), the female screw member 106 is lowered and the locking piece 108 is moved downward from the back surface of the tilt angle fine adjustment plate 8, thereby finely adjusting the tilt angle. The other end of the plate 8 is lowered, thus reducing the tilt angle of the tilt angle fine adjustment plate 8. The tilt angle of the tilt angle fine adjustment plate 8 can be visually confirmed by the position of the tilt angle indicator piece 46 with respect to the tilt angle memory printed on the sheet 88.

To explain a typical example of how the medical support and fixation device 2 is used as described above, during radiation therapy, imaging, nuclear magnetic resonance imaging, etc., the medical support and fixation device 2 is placed on an appropriate bed on which a human body lies. It will be placed. Then, as shown by the two-dot chain line in FIG. 1, a fixing means 118 is attached to the surface of the tilt angle fine adjustment plate 8. The fixing means 118 includes a rectangular plate-shaped substrate 120 and a cover member 122 attached to the substrate 120. Holes 124 are formed on both sides of one end of the substrate 120, and by fitting the holes 124 into projections 48 provided on both sides of the other end of the tilt angle fine adjustment plate 8, the tilt angle can be adjusted. The fixing means 118 can be positioned at a predetermined position with respect to the angle fine adjustment plate 8. The head of the human body is positioned on the substrate 120 and covered and fixed by the cover member 122. Precise positioning of the human head can be achieved by manually operating the input member 62 to finely adjust the yaw angle of the yaw angle fine adjustment plate 6 with respect to the base plate 4, and by manually operating the input member 112 to finely adjust the yaw angle. This is achieved by finely adjusting the tilt angle of the tilt angle fine adjustment plate 8 with respect to the plate 6. The fixing means 118 itself may be of a form well known to those skilled in the art, so a detailed description thereof will be omitted.

Although preferred embodiments of the medical support and fixation device configured according to the present invention have been described above in detail with reference to the accompanying drawings, the present invention is not limited to such embodiments, and does not depart from the scope of the present invention. It goes without saying that various modifications and modifications can be made without any problems.

For example, in the illustrated embodiment, the yaw angle fine adjustment plate 6 is mounted on the base plate 4 via the short shaft member 16 and the bearing member 20 (or bearing hole), and the hinge 36 is mounted on the yaw angle fine adjustment plate 6. A yaw angle fine adjustment mechanism 10 is installed between the base plate 4 and the yaw angle fine adjustment plate 6, and the yaw angle fine adjustment plate 6 and the tilt angle fine adjustment plate are connected to each other.
