Next, with reference to FIGS. 18 to 20, the attitude holding mechanism 61 and the like provided in the observation device 21 will be described. FIG.
8 (A), (C), (B), and (D) show the side and front views of the observation device 21 in a state in which the posture holding mechanism 61 is set to an operation state and in a retracted non-operation state, respectively. 1
9 shows an enlarged main part of FIG. 18B, and FIG. 20 shows a posture holding mechanism 61 on the bottom surface of the observation device 21.

As shown in FIG. 18, the observation device 21 of the present embodiment has an observation device main body 62 and this observation device main body 62.
A frame 63 held so as to sandwich the bottom side and both side surfaces, a caster 64 that allows the observation device 62 to be movable is attached to the bottom surface of the frame 63, and a ceiling frame provided at the upper end of the frame 63 The liquid crystal monitor 25 is mounted on 63a. An operation panel 24 is provided at a front corner of the ceiling frame 63a.

On the front side of the frame 63, a disc-shaped coil unit 23 is vertically movable by a lifting mechanism 65.
Attached to. Further, on the bottom surface of the frame 63, a posture holding mechanism 61 is provided as shown in FIGS.

A hook or hanger 66 for suspending and holding the probe 15 is provided at the upper end of the frame 64. The shape of the observation device 21 is different from the size on the front side.
The vertical size of the side surface is reduced so that it can be installed in a small occupied area close to the side surface of the bed 4.

As shown in FIGS. 19 and 20, the frame 63
The bottom surface (or the bottom plate attached to the bottom of the frame 63) is separated from the rear side to the front side (facing diagonally forward).
Posture holding legs that are almost symmetrically paired in the direction
A leg (only a leg) 71a is a leg storage member 72, and the rear end side is held so as to be able to expand and contract.

The leg storage member 72 has a cylindrical shape, and has legs 71a.
The rear end side of the leg 71a is retractably stored in the leg storage member 72 or is projected forward from the stored state, so that the rear end side of the leg 71a can be retractably stored and held. Further, the distal end of the leg 71a is rotated by approximately 90 degrees as shown by the arrow by the urging force of the spring 73 as shown in FIG.
A rotating leg 71b whose lower end extends is attached to the side.

More specifically, the leg 71a is a frame whose lower side is open, and one end of a rotatable rotating leg 71b is rotatably connected to the tip of the frame 71a. The rotating leg 71b is urged to rotate and the rotating leg 71b is
(The storage state is indicated by a two-dot chain line in FIG. 19). Therefore, as shown in FIGS. 18A and 18B (or an enlarged view of FIG. 19), when the leg 71a is pulled out from the stored state of FIGS. As shown in FIG. 19 and the like, the distal end side of the leg 71a projects outward from the bottom surface of the frame 63, and by pulling out (from the leg storage member 72), the rotating leg 71b indicated by a two-dot chain line is provided with a spring 73. It is rotated by the force as shown by the arrow so that its lower end is located at a position slightly separated from the floor surface 74. Since the lower end of the rotating leg 71b is slightly separated from the floor surface 74, it does not hinder the movement of the observation device main body 62 by the casters 64.

Therefore, in this state, if the observation device 21
Alternatively, when a force is applied to the frame 63 to defeat it, and the frame 63 is slightly inclined,
Has a function of holding the posture to prevent the lower end of the abutment against the floor surface 74 to prevent the lower end from being further inclined.

Further, since the legs 71a and the rotating legs 71b of the posture holding mechanism 65 can be set in a retracted state so as not to protrude from the position of the bottom surface of the frame 63, even when the observation device 21 is moved, It is possible to prevent the posture holding mechanism 65 from getting in the way.

In FIG. 20, the legs 71a are provided so as to protrude sideways from the bottom surface of the frame 63, but they may be provided so as to protrude forward as shown in FIG. In this case, since the size in the front-back direction is smaller than that in the horizontal direction, the function of holding the posture can be further increased.

In the case shown in FIG. 21, depending on the shape of the lower side of the bed 4, there is a possibility that the distal end side when the leg 71a is protruded may become an obstacle. For this reason, the leg 71 a is provided at a plurality of locations in the longitudinal direction inside the leg storage member 72.
It is preferable to be able to fix by a click mechanism or the like. That is, a plurality of lengths when extended can be changed, and when there is a large space below the bed 4, the legs 71a
In the case where there is no space in the lower part of the bed 4, the length of protruding the leg 71 a is shortened so that the leg 71 a can be used. Is also good.

In the type of extending and retracting the leg 71a shown in FIGS. 18 to 21, when the leg 71a is projected from the leg storage member 72, the rotating leg 71b is rotated by the biasing force of the spring 73 to hold the posture. However, as shown in FIGS. 22 (A) and (B), a bending type which can be set to a posture holding state by bending (by a user manually) or set to a retracted state by bending in the opposite direction is used. Is also good.

In this case, a rotation restricting piece 76 protruding laterally is provided near the rotation supporting portion of the rotation leg 71b, and the lower end of the rotation leg 71b is slightly away from the floor surface 74 in a posture holding state. In this state, the rotation restricting piece 76 is brought into contact with (the bottom surface of the frame body 63) and the rotation is positioned.

In FIG. 22, for simplicity, the rotating legs 7
Although the case where 1b is rotatably mounted on the bottom surface of the frame 63 is shown, it may be mounted on a leg 71a which can protrude from the bottom surface of the frame 63.

FIG. 23 shows the lifting mechanism 6 of the coil unit 23.
5 shows a configuration. If the coil unit 23 is set close to the bed 4, the shape can be detected with higher accuracy. The height of the bed 4 is set by the bed elevating mechanism according to the height of the doctor to be examined. Also, the coil unit 23 can be set up and down near the bed 4 at the height set by the up and down mechanism 65.

The frame 63 has a columnar member 8 extending vertically.
1 is cut out in a triangular shape at a predetermined pitch in the longitudinal direction to form a concave portion 81a (at a portion where the concave portion 81a is not provided) to form a substantially saw-toothed uneven portion. Guide groove (guide hole) to be movable
A coil unit holder 83 provided with 82 is provided (on the coil unit 23 side) so that the coil unit 23 side can be moved up and down, and protrudes from the lateral hole of the coil unit holder 83 toward the sawtooth-shaped uneven portion side of the columnar member 81. Lock piece 8
The coil unit 23 can be set at a desired height position by freely engaging and disengaging the coil unit 23.

The tip of the lock piece 84 protrudes in a triangular shape in which the lower side protrudes from the upper side.
Has a triangular concave shape into which the tip shape of the lock piece 84 fits. By operating the knob 85 on the base end side of the lock piece 84, the lock piece 84 is moved rearward to release the engagement, that is, it can be freely inserted into and removed from the recess 81a. Then, the position for holding the coil unit 23 in the state in which the engagement is released can be moved downward (as well as upward). In a locked state in which the lock piece 84 has its tip engaged with the triangular recess 81a, the lock piece 84 elastically urges the lock piece 84 toward the recess 81a. Further, it is configured to be able to rotate a little in the horizontal hole.

Therefore, as shown in FIG.
In a state where the tip of the lock piece 84 is fitted into the recess 81a, when a force is applied to the coil unit holder 83 so as to push the coil unit holder 83 upward from below, the lock piece 8 engages with the lower wall of the recess 81a.

Has formed. In addition, when a force is applied to the coil unit holder 83 that pushes the coil unit holder 83 from the upper side to the lower side, the coil unit holder 83 cannot retract from the concave portion 81a and does not move downward.

That is, if the coil unit 23 of the observation device 21 is set in a state in which the bed unit 4 is approached,
Even if the bed 4 is moved upward by the bed elevating mechanism and a part of the bed 4 hits the coil unit 23, the coil unit 23 can move up to a position where the force for pushing up from the bed 4 hardly works due to its relief structure. So that the attitude of the observation device 21 can be held effectively.

FIG. 24 shows the probe 15. Since the probe 15 is long, the boundary between the probe insertion portion 15a (with the source coil built in and inserted into the forceps channel 12 of the endoscope 6) and the cable portion 16 formed on the rear end side is provided. The hook 6 shown in FIG.

The probe 15 is suspended from the hook hole 88 through the hook 66 and held in a suspended state. If the tip of the probe insertion portion 15a reaches the floor in this state, the tip side is further used for probe holding. Hole 8
9, the probe 15 can be held without the front end side of the probe 15 coming into contact with the floor and becoming dirty.

In the above description, the hook 66 is provided on the observation device 21 side in FIG. 18 and the like, and the probe 15 shown in FIG.
Although the hook hole 88 for passing the hook 66 is provided on the side, the hook hole may be provided on the observation device 21 side and the hook may be provided on the probe 15 side.

Although not shown, the probe insertion portion 15
a is provided with a display unit indicating the length of the forceps channel 12 of the endoscope 6 into which the probe 15 is inserted and set, and when the probe insertion unit 15a is inserted through the forceps channel 12, depending on the position of the display unit, You may make it understand that the tip of the probe insertion part 15a could be set to the appropriate insertion position which does not protrude from the tip of the forceps channel.

Further, a detachable stopper (not shown) is provided at the rear end side of the probe insertion portion 15a, and the stopper is set at the position of the display portion. When the probe reaches the tip, the probe insertion portion 1
5a may be prevented from being inserted, so that an appropriate insertion state can be set more reliably.

The stopper is usually fixed to the relay portion 87 by screwing or the like, and is inserted into the endoscope 6 so as to be inserted into the insertion port 12a.
When fixedly used at a portion, the position may be set at the position of the display section.
