[ shape of storage tank and lifting platform ]

Next, the shapes of the storage groove 12 and the lift table 13 will be described.

Fig. 3 is a diagram for explaining the shapes of the storage groove 12 and the lift table 13. Specifically, fig. 3 is a sectional view of the rigid member 62 cut by a sectional plane extending along the insertion axis Ax and passing through the housing groove 12. Fig. 3 shows a state in which the lift table 13 is set to the upside down state.

Hereinafter, the upper side of fig. 3 (the side of the opening 121 of the storage groove 12) is referred to as "upper", and the lower side of fig. 3 is referred to as "lower".

In the housing groove 12, the pair of side wall surfaces 122 are each formed of flat surfaces orthogonal to the rotation axis RAx and parallel to each other (see fig. 4).

Further, in the housing groove 12, the bottom 123 has a shape shown below. In the bottom portion 123, hereinafter, the distal end side is referred to as a distal end side bottom portion 123A and the proximal end side is referred to as a proximal end side bottom portion 123B with reference to a 1 st plane PL1 (fig. 3) passing through the rotation axis RAx and orthogonal to the insertion axis Ax.

The distal end side bottom portion 123A is formed of a curved surface which curves upward from a boundary position with the proximal end side bottom portion 123B toward the distal end and the distal end becomes an edge portion of the opening 121. That is, the tip end side of the tip end side bottom portion 123A is constituted by an inclined surface 123C inclined with respect to the 1 st plane PL 1.

The base end bottom portion 123B is formed of a curved surface 123D extending from a boundary position with the tip end bottom portion 123A toward the base end side so as to draw 1/4 a circle centering on the rotation axis RAx, and a flat surface 123E extending upward from the curved surface 123D in parallel with the 1 st flat surface PL1 and having an edge portion of the opening 121 at an upper end. The treatment instrument insertion hole 11 penetrates the plane 123E and communicates with the storage groove 12.

The lift table 13 is constituted by a columnar body extending along the rotation axis RAx.

In the lift table 13, the pair of bottom surfaces 131 of the columnar body are each formed of flat surfaces orthogonal to the rotation axis RAx and parallel to each other (see fig. 4). A fixing hole 131A (see fig. 4) recessed toward the other bottom surface 131 is formed in the rotation axis RAx of one bottom surface 131 of the pair of bottom surfaces 131.

In the lift table 13, the outer peripheral surface 132 of the columnar body has the following shape. In the following, in the lift table 13, the lower side is defined as the lower side outer peripheral surface 132A and the upper side is defined as the upper side outer peripheral surface 132B with reference to the 2 nd plane PL2 passing through the rotation axis Rax and orthogonal to the 1 st plane PL 1.

The lower outer circumferential surface 132A includes a 1 st curved surface 132C curved so as to follow the distal end bottom portion 123A, and a 2 nd curved surface 132D extending from a boundary position on the base end side with the 1 st curved surface 132C so as to follow the curved surface 123D. That is, the lower outer circumferential surface 132A has a shape that matches the shapes of the distal end bottom portion 123A and the curved surface 123D. The lift table 13 is pivotally supported so as to be able to pivot about a position (pivot axis RAx) that is offset upward and toward the distal end side with respect to the distal end side bottom portion 123A and the curved surface 123D and is offset toward the distal end side by a dimension obtained by adding the above-described gap and the radius of curvature of the 2 nd curved surface 132D, so as to form a posture in which a uniform gap is left between the distal end side bottom portion 123A and the lower side outer peripheral surface 132A and between the curved surface 123D and the lower side outer peripheral surface 132A when set in the upside-down state. That is, the lifting table 13 is pivotally supported so as to be rotatable about the center of curvature (the rotation axis RAx) in a state where the center of curvature of the 2 nd curved surface 132D coincides with the center of curvature of the curved surface 123D. Hereinafter, the above gap is referred to as a uniform portion Sp1 (fig. 3).

The upper outer circumferential surface 132B is formed of the 3 rd to 6 th curved surfaces 132E to 132H and a flat surface 132I.

The 3 rd curved surface 132E is a curved surface extending circularly from a boundary position on the base end side between the 3 rd curved surface 132E and the lower outer circumferential surface 132A (a boundary position on the base end side between the 2 nd curved surface 132D) toward the tip end side with a curvature drawing 1/4 identical to that of the 2 nd curved surface 132D.

The 4 th curved surface 132F is a curved surface that curves upward from the boundary position on the distal end side between the 4 th curved surface 132F and the 3 rd curved surface 132E toward the distal end.

The 5 th curved surface 132G is a curved surface curved in an arc shape from a boundary position on the tip end side between the 5 th curved surface 132G and the 4 th curved surface 132F so as to protrude upward toward the tip end side.

The flat surface 132I is a flat surface extending parallel to the 1 st flat surface PL1, and faces downward from the boundary position on the tip end side between the lift table 13 and the 5 th curved surface 132G in the state where the lift table 13 is set in the upside-down state.

Further, a concave groove 132J (fig. 3) having a U-shaped cross section is formed from the 4 th curved surface 132F and the 5 th curved surface 132G to the flat surface 132I in the outer circumferential surface 132, and the treatment instrument Tt inserted into the storage groove 12 through the treatment instrument insertion hole 11 is placed in the concave groove 132J.

The 6 th curved surface 132H is a curved surface connecting the flat surface 132I and the lower outer circumferential surface 132A, and is curved in an arc shape from a lower boundary position between the curved surface and the flat surface 132I to a base end side so as to be convex downward with a curvature smaller than that of the distal end side bottom portion 123A.

When the lift table 13 is set to the upside down state, as shown in fig. 3, the gap between the 6 th curved surface 132H and the distal end side bottom portion 123A and the gap between the 3 rd curved surface 132E and the base end side bottom portion 123B are larger than the gap of the uniform portion Sp 1. Hereinafter, these gaps are respectively referred to as the introduction portions Sp2 and Sp3 (fig. 3).

That is, a cleaning space Sp (fig. 3) is formed between the bottom 123 and the lift table 13, and when the lift table 13 is set in the inverted state, the cleaning space Sp is constituted by a uniform portion Sp1 and introducing portions Sp2 and Sp3, which are continuous from the tip end side to the base end side and open at both ends of the tip end side and the base end side.

It is also preferable that the radius of curvature of the 2 nd curved surface 132D, the 3 rd curved surface 132E, and the curved surface 123D is two times or more and less than 5 times the gap of the uniform portion Sp 1.

Then, the raised table cleaning brush 100 (see fig. 6A and 6B) is inserted into the cleaning space Sp to clean the space between the bottom 123 and the raised table 13.

The detailed structure of the lift-table cleaning brush 100 will be described later.

The above-described lifting table 13 is rotated by a rotating mechanism 14 (see fig. 4 and 5) in conjunction with the operation of the operation unit 7 by the doctor or the like.

The structure of the turning mechanism 14 will be explained below.

[ Structure of rotating mechanism ]

Fig. 4 and 5 are sectional views showing the structure of the rotating mechanism 14. Specifically, fig. 4 is a view of a part of a cross section of the hard member 62 cut by a cutting plane passing through the 1 st plane PL1, as viewed from the proximal end side. Fig. 5 is a part of a cross section of the rigid member 62 cut by a cross-sectional plane passing through the 3 rd plane PL3 shown in fig. 4. In fig. 4 and 5, the lifting table 13 is set in an upside-down state as in fig. 3.

As shown in fig. 4 or 5, the rotating mechanism 14 is located on the side of the storage groove 12, and is disposed in a recess 69 recessed from the outer surface of the rigid member 62 toward the storage groove 12 (side wall surface 122).

As shown in fig. 4, a circular hole 691A is formed in the recessed portion 69 on the rotation axis RAx of the bottom 691, and the circular hole 691A penetrates through the one side wall surface 122 of the storage groove 12.

As shown in fig. 4, a cover 693 is attached to an opening 692 of the recess 69. The cover 693 has substantially the same planar shape as the opening 692, and closes the recess 69 by being attached to the opening 692. A circular hole 693A penetrating inside and outside is formed in the rotation axis RAx of the cover 693.

Further, as shown in fig. 4 or 5, the turning mechanism 14 includes: a bearing member 15, a rotation member 16, and an operation wire 17.

The bearing member 15 has an outer surface shape substantially equal to the inner surface shape of the recess 69, is fitted (fixed) to the recess 69, and rotatably supports the rotary member 16.

As shown in fig. 4 or 5, a concave portion 151 that is recessed from the opening 692 side toward the bottom 691 side is formed on the surface of the bearing member 15 on the opening 692 side. A circular hole 152 communicating with the storage groove 12 via a circular hole 691A is formed in the bottom of the recess 151. Further, a circular frame-shaped shaft support portion 153 that protrudes from the edge portion of the circular hole 152 toward the accommodating groove 12 and fits into the circular hole 691A is formed on the bottom portion.

The rotating member 16 is a member that is pivotally supported so as to be rotatable about a rotation axis RAx with respect to the bearing member 15 and the cover 693, and rotates the lift table 13. As shown in fig. 4 or 5, the rotating member 16 includes a rotating member main body 161 (fig. 4), an extension 162, and a projection 163.

The rotating member main body 161 has a cylindrical shape extending along the rotation axis RAx, and one end side thereof is fitted (fixed) in the fixing hole 131A. The rotary member main body 161 is inserted into the shaft support portion 153 and is rotatably supported about the rotation axis RAx together with the lift table 13.

The protruding portion 162 is provided at the other end of the rotating member main body 161, and is formed of a plate body protruding to the outside (the side away from the rotation axis RAx) of the outer peripheral surface of the rotating member main body 161, and the protruding portion 162 is positioned in the concave portion 151.

The protrusion 163 has a cylindrical shape protruding from the plate surface of the protruding portion 162 on the side opposite to the plate surface connected to the rotating member main body 161 and extending along the rotation axis RAx. The protrusion 163 is inserted into the circular hole 693A and is pivotally supported so as to be rotatable about the rotation axis RAx.

The operation wire 17 is wound around the inside of the operation portion 7, the flexible tube 64, the bending portion 63, and the rigid member 62, and one end of the operation wire 17 is connected to the operation portion 7 and the other end thereof is connected to the protruding portion 162 in the concave portion 151. The operation wire 17 transmits power to the rotation member 16 in accordance with the user operation of the operation unit 7 by the doctor or the like.

Specifically, when the operation wire 17 is pulled toward the base end side in accordance with a user operation performed on the operation portion 7 by a doctor or the like, the rotation member 16 rotates counterclockwise in fig. 5 centering on the rotation axis RAx. The lift table 13 is rotated together with the rotation member 16, and is set in a raised state lifted from the insertion axis Ax by rotating the rotation axis RAx in the clockwise direction in fig. 3 as the center.

On the other hand, when the user operates the operation unit 7 by a doctor or the like to release the operation wire 17 from being pulled toward the proximal end side (to return the operation wire 17 toward the distal end side), the rotation member 16 rotates the rotation axis RAx clockwise in fig. 5 about the rotation axis RAx until the protruding portion 162 abuts on the side wall surface 154 (fig. 5) of the concave portion 151. Then, the lift table 13 rotates counterclockwise in fig. 3 about the rotation axis RAx together with the rotation member 16 until the projecting portion 162 abuts on the side wall surface 154. That is, before the lift table 13 rotates counterclockwise in fig. 3 and abuts on the bottom portion 123, the bearing member 15 (the side wall surface 154) abuts on the projecting portion 162, and further rotation of the lift table 13 is restricted. Then, in a state where the side wall surface 154 and the protruding portion 162 are in contact, the lift table 13 is set in an inverted state (fig. 3 to 5) inverted from the lifted state.

[ Structure of brush for cleaning raised table ]

As shown in fig. 6A, the plurality of shaft members 102 extend from the side end portion 101A so as to be parallel to the normal direction of the side end portion 101A. That is, the plurality of shaft members 102 are arranged in parallel with each other. The shaft members 102 are arranged such that a plane PL4 (fig. 6B) including the shaft members 102 is parallel to the plate surface PL5 (fig. 6B) of the lever 101.

The plurality of bristles 103 correspond to the 1 st to 3 rd bristles of the present invention, have the same cross-sectional shape and length dimension, and are made of a bristle-like material such as a synthetic resin. The plurality of brush staples 103 are implanted on the entire outer peripheral surfaces of the plurality of shaft members 102. For example, the brush 103 is implanted in the shaft member 102 by being sandwiched between a plurality of wires constituting the shaft member 102 and twisting the plurality of wires with each other. When 1 shaft member 102 is viewed from the distal end side, the locus of the distal ends of the connecting bristles 103 has a substantially circular shape as shown in fig. 6B.

The fixing portion 104 is a portion for fixing the distal ends of the plurality of shaft members 102 to each other.

[ dimensional relationship between cleaning space and cleaning brush for lifting table ]

Next, the dimensional relationship between the cleaning space Sp and the lift table cleaning brush 100 will be described with reference to fig. 3, 4, 6A, and 6B.

The width d1 (fig. 6A) of the plurality of bristles 103 is set to about 2.8mm to 4.2 mm. The width D1 is set to be larger than the width D1 (fig. 4) of the cleaning space Sp (the length along the rotation axis RAx).

The thickness d2 (fig. 6B) of the plurality of bristles 103 is set to about 0.6mm to 1.2 mm. The thickness D2 is set to be larger than a gap D2 (fig. 4) between the bottom 123 of the cleaning space Sp (the uniform part Sp1) and the lift table 13.

The length d3 (fig. 6A) of the plurality of bristles 103 is set to about 8mm to 20 mm. The length D3 is set to be larger than the length D3 (fig. 3) of the cleaning space Sp (length connecting the openings at both ends to each other).

The above-described brush 100 for cleaning a lift table of the present embodiment has the following effects.

Fig. 7A and 7B are diagrams for explaining the effects of the present embodiment. Specifically, fig. 7A is a cross-sectional view corresponding to fig. 3. Fig. 7B is a sectional view corresponding to fig. 4.

The lift table cleaning brush 100 of the present embodiment includes: a handle 101, a plurality of shaft members 102, and a plurality of bristles 103. The cleaning space Sp and the lift table cleaning brush 100 have the above-described dimensional relationship. Therefore, as shown in fig. 7A and 7B, for example, when the platform cleaning brush 100 is inserted into the cleaning space Sp from the distal end side of the insertion portion 6, the platform cleaning brush 100 can be inserted from the distal end side to the proximal end side of the cleaning space Sp. Further, the tips of the plurality of brush staples 103 can be brought into contact with the entire wall surface constituting the cleaning space Sp. Then, when the lift table cleaning brush 100 is moved forward and backward in the cleaning space Sp, the entire gap between the bottom portion 123 and the lift table 13 can be collectively brushed by the lift table cleaning brush 100.

Therefore, the use of the platform cleaning brush 100 according to the present embodiment has the effect of simplifying the cleaning operation and reducing the operation time required for cleaning.

In the lift table cleaning brush 100 of the present embodiment, the handle 101 has a flat plate shape. Further, a plurality of shaft members 102 are provided at the side end portion 101A. Therefore, for example, when the raised platform cleaning brush 100 is inserted into the cleaning space Sp from the distal end side of the insertion portion 6, the handle 101 can be positioned near the introduction portion Sp2 of the cleaning space Sp, and the distance of moving the raised platform cleaning brush 100 forward and backward can be increased. Therefore, the raised platform cleaning brush 100 can be downsized without unnecessarily extending the length dimensions of the plurality of shaft members 102 (the plurality of brush staples 103).

In the lift table cleaning brush 100 of the present embodiment, the plurality of shaft members 102 are arranged such that a plane PL4 including the plurality of shaft members 102 is parallel to the plate surface PL5 of the handle 101. Therefore, the user can easily insert the platform cleaning brush 100 into the cleaning space Sp by simply checking the posture of the handle 101.

Further, the brush 100 for cleaning a lift table of the present embodiment further includes a fixing portion 104 for fixing the distal ends of the plurality of shaft members 102 to each other. Therefore, even when the lift table cleaning brush 100 is used for a long period of time, the distal ends of the plurality of shaft members 102 are prevented from being separated from each other, and the insertion performance of the lift table cleaning brush 100 into the cleaning space Sp can be maintained well.
