[0071] (First Implementation)

[0072] Reference Figures 1 to 29 The box system 100 of the first embodiment of the present invention will be described. The box system 100 includes a clamping unit 1 and a box 5 for storing the clamping unit 1. The box system 100 is a support system for easily loading the clamping unit 1 into the clamping guide device 200.

[0073] [Clamping guide device 200]

[0074] Figure 1 This is a perspective view of the clamping guide device 200.

[0075] The clamp guide device 200 includes a sheath 220, an operating line 230, and an operating section 240. The clamp guide device 200 extends, for example, through the instrument passage of an endoscope and is used in conjunction with the endoscope. Therefore, the sheath 220 is formed to be sufficiently long compared to the length of the instrument passage of the endoscope. The sheath 220 is flexible and bends to accommodate the bending of the insertion portion of the endoscope.

[0076] The sheath 220 includes a front end head 221, a front side coil 222, and a side coil 224, and is formed into a slender tubular shape. The front side coil 222 is disposed on the front end side of the sheath 220. The front end head 221 is disposed on the front end of the front side coil 222.

[0077] like Figure 1 As shown, the operation line (power transmission part) 230 includes an arrow hook part (connection part) 231 connected to the clamp unit 1 and a line 232 for operating the arrow hook part 231.

[0078] The arrow hook portion 231 includes a generally conical engaging portion 231a that engages with the clamp unit 1, and a wire connecting portion 231b provided at the base end of the engaging portion 231a. The arrow hook portion 231 is formed of a metal material such as stainless steel.

[0079] The wire 232 passes through the sheath 220 in a manner that allows it to move freely in and out of the sheath 220. The front end of the wire 232 is fixed to the base end of the wire connector 231b, for example, by welding.

[0080] like Figure 1As shown, the operating part 240 includes an operating part body 241, a slider 242, and a thumb ring 248. The operating part body 241 is injection molded, for example, using resin material. The operating part body 241 includes a slit portion 241a and a rotating handle 241b located at the front end. The slit portion 241a supports the slider 242 so that it can move forward and backward.

[0081] The slider 242 is mounted in a manner that allows it to move forward and backward along the longitudinal axis of the operating part body 241, and the base end of the wire 232 is mounted thereon. As the slider 242 moves forward and backward along the operating part body 241, the wire 232 moves forward and backward relative to the sheath 220, and the arrow hook portion 231 moves forward and backward.

[0082] The thumb ring 248 is mounted on the base of the operating part body 241 in such a way that it can rotate about the length axis of the operating part body 241.

[0083] [Clamping Unit 1]

[0084] Figure 2 This is a perspective view of the clamping unit 1 of the box system 100 in this embodiment. Figure 3 This is a perspective view of the clamping unit 1 of the pressure tube 3. The clamping unit 1 includes a clamp 2, a pressure tube 3 as a fastening member, and a connecting member 4.

[0085] The clamp 2 is formed, for example, by bending a metal sheet such as a leaf spring made of stainless steel at its central portion. The clamp 2 has a pair of arms 21 that can be opened and closed and a connecting portion 22 that connects the pair of arms 21.

[0086] The pair of arms 21 have a first arm 211 and a second arm 212. The first arm 211 and the second arm 212 are symmetrically arranged with respect to the central axis O1 in the longitudinal direction of the clamping unit 1. Tissue holding portions 23 are formed at the front ends of the pair of arms 21, facing each other. The tissue holding portions 23 are formed by bending the front ends of the pair of arms 21 inward.

[0087] Engaging portions 24 protruding in a direction perpendicular to the central axis O1 are formed on the base end side of the first arm 211 and the base end side of the second arm 212. The tissue holding portion 23 side of the engaging portion 24 is formed as an acute-angled slope, and the connecting portion 22 side of the engaging portion 24 is formed as an obtuse-angled slope.

[0088] The first arm 211 and the second arm 212 are connected at their base ends by a connecting portion 22, allowing them to open and close freely toward the front end. The connecting portion 22 is bent into a U-shape and connected to the connecting member 4. The connecting portion 22 applies force to open the pair of arms 21. Therefore, the pair of arms 21 of the clamp 2 have a self-expanding force in the opening and closing direction P.

[0089] The crimping tube 3 has a submerged wing 31 and a crimping tube body 30 formed in a cylindrical shape. The crimping tube body 30 is formed by injection molding of a high-rigidity resin material with moderate elasticity, which is softer than the clamp 2, such as PPA (polyphthalamide) or PA (polyamide). Alternatively, the crimping tube body 30 may be formed of metal instead of a high-rigidity resin material.

[0090] The submersion wing 31 is a pair of protrusions that protrude into the outer peripheral surface 30a of the pressure pipe body 30. The submersion wing 31 is provided on both sides with a central axis O1 between them. The basic posture is the protruding state in which the submersion wing 31 protrudes radially outward relative to the outer peripheral surface 30a. The submersion wing 31 is in the submerged state relative to the outer peripheral surface 30a by bearing a force from the radially outward to the inward. By releasing the above-mentioned force, the submersion wing 31 returns from the submerged state to the protruding state.

[0091] The connecting member 4 is connected to the connecting portion 22 of the clamp 2. Furthermore, the connecting member 4 is connected to the arrow hook portion 231 that penetrates the sheath 220. That is, the connecting member 4 connects the clamp 2 and the arrow hook portion 231. The connecting member 4 includes an insertion portion 41 that is inserted into the internal space of the pressure tube 3 and a connecting portion 42 provided at the base end of the insertion portion 41.

[0092] The insertion part 41 has a hook 41f at its front end. The hook 41f is a hook extending in a direction perpendicular to the central axis O1 and is formed into a generally cylindrical rod shape. The connecting part 22 of the clamp 2 is hooked on the hook 41f. When the connecting part 22 is pulled towards the base end and a tensile breaking force of, for example, 20 N (Newtons) to 60 N is applied to the hook 41f, the hook 41f breaks.

[0093] The connecting part 42 is an engaging part that engages (connects) with the arrow hook part 231 of the clamp guide device 200. The connecting part 42 has a connecting part body 43 and an elastic arm part 44.

[0094] An elastic arm 44 is provided at the base end of the connecting body 43, and branches into two forks. The elastic arm 44 can elastically deform relative to the connecting body 43 and can open and close relative to the connecting body 43. A notch 44m is formed in the elastic arm 44, which holds and receives the engaging portion 231a of the arrow hook portion 231. The notch 44m is shaped to fit tightly against the outer peripheral surface of the engaging portion 231a of the arrow hook portion 231.

[0095] Next, the function of fixture unit 1 will be explained.

[0096] The connecting part 22 of the clamp 2 is inserted into the internal space of the pressure tube 3 through the front opening 3a and connected to the connecting member 4. By using the connecting member 4 to pull the connecting part 22 towards the base end of the pressure tube 3, a pair of arms 21 are pulled into the pressure tube 3, and the pair of arms 21 gradually close. If the pulling force of the connecting part 22 is released in this state, the self-expanding force of the pair of arms 21 is used as a restoring force, and the clamp 2 moves towards the front end and returns to the open state.

[0097] By further pulling the connecting portion 22 toward the base end of the compression tube 3, the engaging portion 24 is pulled into a position closer to the base end opening 3b. Since the connecting portion 22 side of the engaging portion 24 is formed with an obtuse-angled slope, the engaging portion 24 is easily pulled into a position closer to the base end opening 3b. On the other hand, since the tissue holding portion 23 side of the engaging portion 24 is formed with an acute-angled slope, if the engaging portion 24 is pulled into a position closer to the base end opening 3b, the engaging portion 24 engages with the base end opening 3b. As a result, the engaging portion 24 cannot enter the internal space of the compression tube 3, and the pair of arms 21 are locked in a closed state. If the pair of arms 21 are locked in a closed state, the pair of arms 21 cannot be restored to an open state.

[0098] [Box 5]

[0099] Figure 4 This is a perspective view of box 5 containing clamp unit 1. Figure 5 This is a cross-sectional view of the box 5 containing the clamp unit 1. The box 5 has a housing 6 and a limiting member 7. The length of the box 5 in the longitudinal direction L is about 50 mm, the width is about 10 mm to 20 mm, and the thickness (height) is about 5 mm, forming a size that is easy to hold.

[0100] like Figure 4 As shown, one of the two directions perpendicular to and mutually perpendicular to the length direction L of box 5 is designated as the "width direction W", and the other direction is designated as the "height direction H". Furthermore, the surface parallel to both the length direction L and the width direction W is designated as the "horizontal plane HP". The surface parallel to both the length direction L and the height direction H is designated as the "vertical plane VP". Additionally, in box 5 housing the clamping unit 1, the side of the pair of arms 21 is designated as the front end side of box 5, and the side of the connecting member 4 is designated as the base end side of box 5.

[0101] The housing 6 has a housing body 60, a clamping part 65, and a sheath connecting part 66. The housing 6 is manufactured, for example, by injection molding using a transparent resin material with moderate hardness, such as ABS, PC, PP, PS, acrylic, or cyclic olefin polymers. By using a transparent resin material to form the housing 6, the user can easily determine whether the clamping unit 1 is present inside.

[0102] The shell body 60 is formed in a rectangular box shape. The length of the shell body 60 in the width direction W is longer than the length of the shell body 60 in the height direction H.

[0103] The housing body 60 has a receiving region 6S for accommodating the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The receiving region 6S has a first region 61, a second region 62, and a closing portion 63. Figure 5 As shown, the first region 61, the second region 62, and the closing portion 63 are arranged from the front end toward the base end in the length direction L. The first region 61, the second region 62, and the closing portion 63 are formed as an internal space symmetrical about the vertical plane VP with respect to the central axis O2 of the length direction L of the containing box 5.

[0104] Figure 6 This is a cross-sectional view of box 5 before it houses fixture unit 1.

[0105] The clamping unit 1 is received in the receiving area 6S from the front opening 60b formed on the front end side of the receiving area 6S of the shell body 60. The clamping unit 1 is received in the box 5 from the connecting member 4 side.

[0106] like Figure 6 As shown, the clamping unit 1 is housed in the receiving area 6S with its central axis O1 along the length direction L. The clamping unit 1 is also housed in the receiving area 6S with the opening and closing directions P of the pair of arms 21 aligned with the width direction W of the housing 6.

[0107] The first region 61 is an internal space that accommodates the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The first region 61 is connected to the second region 62. The first region 61 has a locking part 64.

[0108] Figure 7 This is a perspective view of the housing 6 without the fixture unit 1.

[0109] The locking part 64 is formed on the front end side of the first region 61 and on the side (upper side) in the height direction H.

[0110] Figure 8 This is a three-dimensional view representing the locking part 64.

[0111] The locking part 64 has an elastically deformable part 64a and a locking protrusion 64b. The elastically deformable part 64a is formed in the shape of a flat plate, and only the end 64c on the front end side in the length direction L is fixed to the shell body 60. The elastically deformable part 64a is elastically deformable as a cantilever beam with the end 64c fixed to the shell body 60 as the fixed end.

[0112] Figure 9 From Figure 7 The direction of the arrow shown is observed in the front view of housing 6.

[0113] The locking protrusion 64b is provided at the end 64d on the base end side of the elastically deformable portion 64a in the length direction L. For example... Figure 9 As shown, the locking protrusion 64b protrudes towards the first region 61 of the receiving region 6S (initial state) without the application of external force. The locking protrusion 64b has an inclined surface 64s and a locking surface 64t.

[0114] An inclined surface 64s is formed on the front end side of the locking protrusion 64b along the length direction L. The inclined surface 64s is inclined relative to the central axis O2, and the normal of the inclined surface 64s faces the front end side along the length direction L.

[0115] The locking surface 64t is formed on the base end side of the locking protrusion 64b in the length direction L. The locking surface 64t is formed as a plane that is approximately perpendicular to the central axis O2, and the normal of the locking surface 64t is directed toward the base end side in the length direction L.

[0116] The second region 62 is an internal space that accommodates the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The length of the second region 62 in the longitudinal direction L is shorter than the length of the first region 61 in the longitudinal direction L. The second region 62 is connected to the closing part 63.

[0117] like Figure 6 As shown, the length W1 of the width direction W of the first region 61 is less than the opening width W3 of the pair of arms 21 in the open state. Furthermore, the length W2 of the width direction W of the second region 62 is greater than the opening width W3 of the pair of arms 21 in the open state.

[0118] The second region 62 has openings 62b on both sides in the width direction W. The edges of the openings 62b are formed into a rectangular shape and extend along the height direction H and the length direction L.

[0119] The closing portion 63 has an expanded diameter portion 63a, a tapered portion 63b, and a reduced diameter portion 63c. The expanded diameter portion 63a, the tapered portion 63b, and the reduced diameter portion 63c are arranged from the front end toward the base end.

[0120] The expansion section 63a is a region that allows the elastic arm 44 of the connecting member 4 to expand (open and close) elastically. In the expansion section 63a, when the arrow hook 231 of the clamp guide device 200 engages with the connecting member 4 of the clamp unit 1, the elastic arm 44 of the connecting member 4 (see reference)... Figure 2 , Figure 3 It can be opened and closed in a direction perpendicular to the central axis O1.

[0121] A tapered portion 63b is provided on the base end side of the enlarged diameter portion 63a and is formed into a tapered shape. The tapered portion 63b expands in diameter from the base end side toward the front end side. Therefore, when the pressure tube 3 slides from the front end side toward the base end side, the protruding wing 31 of the pressure tube 3 is housed inside the pressure tube body 30.

[0122] The reduced diameter section 63c is the area that keeps the submerged wing 31 in a submerged state. For example... Figure 5 As shown, when the clamping unit 1 is housed in the box 5, the reduced diameter portion 63c can maintain the elastic arm 44 in a state that prevents the elastic arm 44 of the connecting member 4 from expanding.

[0123] When the pressure tube 3 slides from the front end side toward the base end side in the tapered portion 63b, the submerged wing 31 of the pressure tube 3 is housed inside the pressure tube 3. Therefore, the reduced diameter portion 63c, which is smoothly connected to the tapered portion 63b, can hold the pressure tube 3 in a state where the submerged wing 31 of the pressure tube 3 is housed (submerged state).

[0124] like Figure 4 As shown, the clamping part 65 is a plate-shaped member provided at the base end of the shell body 60. The clamping part 65 has a first clamping part 651 and a second clamping part 652. The first clamping part 651 and the second clamping part 652 are provided opposite to each other in the height direction H of the shell 6.

[0125] The clamping portion 65 has a connecting portion 65a that connects to the shell body 60. The connecting portion 65a connects the first clamping portion 651 and the second clamping portion 652 to the shell body 60, respectively. The connecting portion 65a is bent such that the first clamping portion 651 and the second clamping portion 652 are separated from each other. Therefore, a gap 65b is formed between the first clamping portion 651 and the second clamping portion 652. The first clamping portion 651 and the second clamping portion 652 are further separated at the base end than at the front end side.

[0126] The first pressing part 651 and the second pressing part 652 are, for example, about 20 mm square, and are shaped to fit the size of a finger grip. On the outer surface of the first pressing part 651 and the outer surface of the second pressing part 652, a plurality of, for example, hemispherical recesses 65c are formed as anti-slip elements when pressing.

[0127] The sheath connecting portion 66 is an insertion groove into which the sheath 220 can be inserted. The sheath connecting portion 66 is an arc-shaped groove formed on the inner surfaces of the first pressing portion 651 and the second pressing portion 652, communicating with the reduced-diameter portion 63c of the closing portion 63 of the receiving region 6S. The sheath connecting portion 66 has a straight portion 66a with a constant diameter and a tapered portion 66b that gradually expands in diameter towards the base end opening 67. The sheath 220 enters the straight portion 66a via the tapered portion 66b and abuts against the base end side of the reduced-diameter portion 63c. The inner diameter of the base end opening 67 is, for example, 3 mm or more.

[0128] The user can fix the sheath 220 relative to the housing 6 by pressing the first clamping part 651 and the second clamping part 652 together while inserting the sheath 220 from the base opening 67 into the sheath connection part 66.

[0129] Figure 10 This is a three-dimensional view of the limiting component 7.

[0130] The restraining member 7, together with the clamping unit 1, is movably accommodated in the first region 61 and the second region 62. The restraining member 7 is, for example, formed of the same resin as the housing 6. The restraining member 7 may also be formed of a different resin than the housing 6. Figure 10 As shown, the limiting member 7 is formed in a shape that is symmetrical with respect to the vertical plane VP of the central axis O3 of the length direction L containing the limiting member 7.

[0131] The limiting member 7 has a middle layer member 70 and an auxiliary member 8. The middle layer member 70 has a front end 71, a protrusion 72, a sloped surface 73, and a pressing part 74. The front end 71, the protrusion 72, the sloped surface 73, and the pressing part 74 are arranged from the front end toward the base end along the central axis O3 of the limiting member 7.

[0132] Figure 11 It is a perspective view of the limiting member 7 held by a pair of arms 21.

[0133] The limiting member 7 is held in the clamp 2 with its central axis O3 approximately aligned with the central axis O1 of the clamp unit 1. For example... Figure 5 As shown, the clamp unit 1 is housed in the receiving area 6S with the clamp 2 holding the limiting member 7. In this case, it is preferable that the central axis O1, central axis O2 and central axis O3 are aligned.

[0134] The front end portion 71 protrudes from the protrusion 72 toward the front end side. The front end of the front end portion 71 is located at a position closer to the front end than the tissue holding portion 23 of the clamp 2 of the holding and restricting member 7. Furthermore, the front end portion 71 is formed into a plane perpendicular to the central axis O3.

[0135] The protrusion 72 is a member that protrudes in a direction perpendicular to the central axis O3 (hereinafter referred to as the "protrusion direction P"). The protrusion 72 is located on both sides of the central axis O3. The protrusion 72 is held by the first arm 211 and the second arm 212. The opening and closing direction P of the pair of arms 21 holding the protrusion 72 is approximately the same as the protrusion direction P of the protrusion 72. The curvature of the outer peripheral surface of the protrusion 72 is less than the curvature of the inner peripheral surface of the tissue holding portion 23. Therefore, the pair of arms 21 can reliably hold the protrusion 72.

[0136] The slope portion 73 is a component formed in the shape of a slope. The slope portion 73 is provided on both sides across the central axis O3. The length of the slope portion 73 in the protruding direction P is shorter than the length of the protruding portion 72 in the protruding direction P. The closer the slope portion 73 is to the base end, the shorter its length in the protruding direction P becomes.

[0137] The pressing part 74 is a plate-shaped member that limits the minimum approach distance between the clamp 2 and the pressure tube 3. The pressing part 74 is provided on the base end side of the slope surface 73. Because the pressing part 74 engages with the edge of the front opening 3a, it cannot enter the internal space of the pressure tube 3 from the front opening 3a. Therefore, even when the clamp 2 is pulled towards the pressure tube 3, the minimum approach distance between the clamp 2 and the pressure tube 3 is limited by the engagement of the pressing part 74 with the edge of the front opening 3a.

[0138] The auxiliary member 8 adjusts the position of the limiting member 7 in the height direction H so that the protrusion 72 is held by a pair of arms 21. The auxiliary member 8 has an upper auxiliary member 81 provided on one side (upper side) in the height direction H and a lower auxiliary member 82 provided on the other side (lower side) in the height direction H. The middle member 70 is clamped by the upper auxiliary member 81 and the lower auxiliary member 82 in the height direction H. In addition, the auxiliary member 8 is not required when it is not necessary to adjust the position of the limiting member 7 in the height direction.

[0139] An engaging recess 83 is formed on one side (upper side) in the height direction H of the upper auxiliary member 81. The engaging recess engages with the engaging protrusion 64b of the locking part 64. In addition, if the auxiliary member 8 is not required, the engaging recess 83 may be provided in at least a portion of the front end 71, the protrusion 72, and the sloped part 73.

[0140] The engaging recess 83 is rectangular in shape when viewed from above in the height direction H. The area of ​​the upper auxiliary member 81 where the engaging recess 83 is not formed is U-shaped when viewed from above.

[0141] like Figure 10 As shown, the engaging recess 83 has a engaging surface 84 on its base end side in the length direction L, which engages with the engaging protrusion 64b of the engaging portion 64. The engaging surface 84 is formed as a plane that is substantially perpendicular to the central axis O3. On the other hand, the engaging recess 83 has a notch 85 formed on its front end side in the length direction L. Therefore, the recessed space 86 of the engaging recess 83 communicates with the space on the front end side in the length direction L.

[0142] When the limiting member 7 moves from the base end side to the front end side in the first region 61, the locking surface 64t of the locking part 64 abuts against the locking surface 84 through the notch 85 and the recess 86.

[0143] Figure 12 This is a top view of the middle layer member 70 of the limiting member 7.

[0144] The portion of the protrusion 72 that protrudes to its maximum extent from the central axis O3 in the protrusion direction P is designated as the maximum protrusion point 72b. The length W4 between the maximum protrusion points 72b is slightly less than the length W1 of the width direction W of the first region 61. The length from the maximum protrusion point 72b to the base of the pressing part 74 in the direction of the central axis O3 is designated as L2.

[0145] Figure 13 This is a top view of the intermediate component 70 held in the first region 61.

[0146] The restraining member 7 is accommodated in the first region 61 in a state of being held by a pair of arms 21. The length W1 of the first region 61 in the width direction W is less than the opening width W3 of the pair of arms 21 in the open state (see reference). Figure 6 Therefore, the pair of arms 21 hold the limiting member 7 in a closed state from the open state. The opening width of the pair of arms 21 is approximately the length W1 of the width direction W of the first region 61. The pair of arms 21 abut against the shell body 60 in the opening / closing direction P. The length from the contact point 72c between the pair of arms 21 and the shell body 60 to the base end of the pressing part 74 in the direction of the central axis O3 is defined as L1.

[0147] The length L1 from the contact point 72c to the base end of the pressing part 74 in the direction of the central axis O3 is preferably longer than the length L2 from the maximum protrusion point 72b to the base end of the pressing part 74 in the direction of the central axis O3. The purpose is that when the clamp 2 is pulled towards the base end, the clamp 2 is pulled towards the base end in a way that reliably engages with the limiting member 7.

[0148] like Figure 12 and Figure 13 As shown, the length W4 between the maximum protrusions 72b is slightly less than the length W1 in the width direction W of the first region 61. Therefore, the limiting member 7 is held in a state by the pair of arms 21 in the first region 61.

[0149] The length L3 from the contact point 72c to the front end of the submerged wing 31 in the direction of the central axis O1, O3 (refer to...) Figure 13 L4 is the distance from the front end of the second region 62 to the base end of the tapered portion 63b (refer to...). Figure 6 )above.

[0150] [Method for loading fixture unit 1]

[0151] Next, the function of the box system 100 will be explained. Figures 14-21 This is a diagram illustrating the method of loading the clamp unit 1 using the box 5-direction clamping guide device 200.

[0152] like Figure 14As shown, the user inserts the sheath 220 of the clamp guide device 200 into the receiving area 6S of the housing 6 through the base opening 67 of the sheath connection portion 66. The user uses the clamping portion 65 to press the sheath 220, fixing the sheath 220 relative to the housing 6.

[0153] like Figure 15 As shown, the user advances the operating line 230 relative to the sheath 220 by operating the operating part 240, thereby advancing the arrow hook 231. The arrow hook 231 advances the connecting member 4, thus restricting the advance of the member 7 and the clamping unit 1. By restricting the movement of the member 7 from the base end side to the front end side, the locking surface 84 of the member 7 is restricted from abutting and engaging with the locking surface 64t of the locking part 64. As a result, the clamping unit 1 cannot advance towards the front end from this position. That is, the locking part 64 restricts the passage of the clamping unit 1 moving towards the front end. The advancing arrow hook 231 is clamped by the elastic arm 44 of the connecting member 4 of the clamping unit 1 and connected to the connecting member 4.

[0154] The locking surface 84 of the limiting member 7 is formed as a plane substantially perpendicular to the central axis O3. Furthermore, the locking surface 64t of the locking part 64 is formed as a plane substantially perpendicular to the central axis O2. Therefore, the limiting member 7, moving from the base end side to the front end side, is less likely to push the locking part 64 away from the side (upper side) in the height direction H. Furthermore, when the locking surface 84 of the limiting member 7 abuts against and engages with the locking surface 64t of the locking part 64, the central axis O1 of the clamp unit 1 is less likely to deviate from the central axis O2 of the receiving area 6S.

[0155] Furthermore, even when the limiting member 7 does not have the engaging recess 83, the limiting member 7 abuts against and engages with the engaging surface 64t of the engaging part 64 by moving from the base end side to the front end side. As a result, similarly to the case described above, the advancing arrow hook 231 connects to the connecting member 4.

[0156] like Figure 16 As shown, the user pulls the operating line 230. The clamp 2 of the clamp unit 1 is pulled towards the base end by the connecting member 4 connected to the arrow hook 231. The hook 41f of the connecting member 4 pulls the connecting part 22 of the clamp 2 without breaking. The restraining member 7 moves in the first region 61 of the receiving area 6S in a state of contact with the pair of arms 21. Since the pair of arms 21 with self-expanding force engage with the edge of the front opening 3a of the pressure tube 3, the pressure tube 3 is also pulled towards the base end along with the clamp 2.

[0157] A pair of arms 21 abut against the shell body 60 in the opening / closing direction P in the first region 61. The frictional force generated by the abutment of the pair of arms 21 against the shell body 60 can properly prevent the clamp 2 from being pulled into the internal space of the pressure tube 3, thus preventing the clamp 2 from being locked in a closed state by the pressure tube 3.

[0158] When the clamp 2 is pulled towards the base end, the pressing part 74 of the limiting member 7 engages with the edge of the front opening 3a of the pressure tube 3, thus limiting the minimum approach distance between the clamp 2 and the pressure tube 3. The pressing part 74 abuts against the pressure tube 3 in a state of contact with the pair of arms 21 by the traction of the operating line 230, limiting the relative movement of the limiting member 7 relative to the pressure tube 3. As a result, it is also possible to properly prevent the clamp 2, which is pulled towards the base end by the connecting structure 4, from being pulled into the internal space of the pressure tube 3 and thus locked in a closed state by the pressure tube 3.

[0159] The user pulls the clamp unit 1 further towards the base end. For example... Figure 17 As shown, the crimp tube 3 passes through the closing part 63. The crimp tube 3 slides from the front end side toward the base end side in the narrowing part 63c, and the protruding wing 31 of the crimp tube 3 is housed inside the crimp tube body 30. The crimp tube 3 with the protruding wing 31 housed inside the crimp tube body 30 is pulled into the sheath 220.

[0160] like Figure 17 As shown, the length L3 from the contact point 72c to the front end of the submersible wing 31 in the direction of the central axis O1, O3 is greater than or equal to the distance L4 from the front end of the second region 62 to the base end of the conical portion 63b. Therefore, when the submersible wing 31 of the pressure tube 3 is retracted into the inside of the pressure tube 3, the contact point 72c between the pair of arms 21 and the shell body 60 is located in the first region 61. That is, before the submersible wing 31 is retracted into the inside of the pressure tube 3, the pair of arms 21 hold the restraining member 7 and are not pulled into the internal space of the pressure tube 3.

[0161] like Figure 18 As shown, the user further pulls the operating line 230 to pull the restraining member 7 to the second region 62. The length W2 of the width direction W of the second region 62 is greater than the opening width W3 of the pair of arms 21 in the open state. Therefore, the restraining member 7 is not held by the pair of arms 21 in the second region 62.

[0162] Figure 19 This is a cross-sectional view of the limiting member 7 disposed in the second region 62 of the housing 6.

[0163] The second region 62 has a central region 621 through which the limiting member 7 passes and side regions 622 that are inserted into the central region 621 from both sides in the width direction W. The side regions 622 communicate with the opening 62b.

[0164] The central region 621 is the area through which the limiting member 7 passes along its length direction L. The lengths of the central region 621 in the width direction W and height direction H are slightly greater than the lengths of the limiting member 7 in the width direction W and height direction H. Therefore, the limiting member 7 can pass smoothly through the central region 621.

[0165] The lateral region 622 is the area through which the pair of arms 21, when in the open state, pass. The length H in the height direction of the lateral region 622 is longer than the length H in the height direction of the pair of arms 21. Furthermore, the length H in the height direction of the lateral region 622 is shorter than the length H in the height direction of the central region 621.

[0166] Guide portions 623 protruding in the height direction H are formed on both sides of the side region 622. The thickness h of the guide portion 623 in the height direction H is shorter than the thickness t1 of the upper auxiliary member 81 in the height direction H and the thickness t2 of the lower auxiliary member 82 in the height direction H. Therefore, the pair of arms 21 that are in the open state in the second region 62 do not hook onto the guide portion 623. In addition, the limiting member 7 passes straight through the central region 621 along the guide portion 623.

[0167] like Figure 20 As shown, the user further pulls the operating line 230. The clamp 2 separates from the restraining member 7 and is pulled towards the base end. The restraining member 7 has a beveled surface 73 formed on the base end side of the protrusion 72 held by a pair of arms 21. Therefore, when the restraining member 7 is pulled towards the base end, the pair of arms 21 are less likely to hook onto the restraining member 7.

[0168] Figure 21 This is a diagram illustrating the shape of the restrictive member 7, which is difficult for the clamp 2 to hold.

[0169] If the restricting member 7 is pulled to the second region 62, the pair of arms 21 will not hold the restricting member 7 and will expand to the open width W3. The base end side of the protrusion 72 of the restricting member 7 is shaped so that the trajectory T of the tissue holding part 23 is not easily disturbed when the clamp 2 is pulled. Therefore, when the restricting member 7 is pulled further towards the base end side, the pair of arms 21 are less likely to hook onto the restricting member 7.

[0170] like Figure 22 As shown, the user further pulls the operating line 230. Since the pair of arms 21 do not hold the restraining member 7, there is no restriction on the minimum approach distance between the clamp 2 and the pressure tube 3. The clamp 2, pulled towards the base end, is pulled into the internal space of the pressure tube 3 and into the sheath 220. Alternatively, the clamp 2 can be pulled into the sheath 220 without being pulled into the internal space of the pressure tube 3. Thus, the clamp unit 1 is loaded into the clamp guide device 200. The user releases the clamping part 65 from the sheath 220 and pulls the sheath 220 out of the housing 6.

[0171] [Method for accommodating fixture unit 1]

[0172] Next, the method of accommodating the fixture unit 1 in the box 5 will be described. Figures 23-26 This is a diagram illustrating the method of accommodating the fixture unit 1 in the box 5.

[0173] like Figure 23 As shown, the user closes a pair of arms 21 with their hand or the like, so that the restraining member 7 is held in the pair of arms 21. Then, the user inserts the clamp unit 1 holding the restraining member 7 into the receiving area 6S of the box 5 through the front opening 60b.

[0174] like Figure 24 As shown, the user moves the clamp unit 1 towards the base end by pushing the limiting member 7 towards the base end. The length W1 of the width direction W of the first region 61 is less than the opening width W3 of the pair of arms 21 in the open state (see reference). Figure 6 Therefore, when the pair of arms 21 holding the restraining member 7 are inserted into the first region 61, the first arm 211 contacts one end of the front opening 60b in the width direction W, and the second arm 212 contacts the other end of the front opening 60b in the width direction W. By pushing the restraining member 7 further towards the base end by the user, the pair of arms 21 in contact with the front opening 60b become further closed and are inserted into the first region 61.

[0175] like Figure 25 As shown, when the limiting member 7 moves from the front end side toward the base end side near the locking part 64 of the housing 6, it pushes the locking part 64 away in the height direction H (upper side) and passes through. Figure 8 As shown, the locking part 64 is elastically deformable as a cantilever beam with the end 64c on the front end side in the length direction L as the fixed end and the end 64d on the base end side in the length direction L as the free end. Therefore, the limiting member 7, which moves from the front end side to the base end side, can easily cause the locking part 64 to elastically deform and push it away.

[0176] like Figure 8 As shown, an inclined surface 64s is formed on the front end side of the locking protrusion 64b in the length direction L. When the limiting member 7, which moves from the front end side to the base end side, contacts the locking protrusion 64b of the locking part 64, the limiting member 7 contacts the inclined surface 64s. Therefore, the limiting member 7, which moves from the front end side to the base end side, can easily push the locking part 64 away to one side (upper side) in the height direction H.

[0177] Furthermore, even if the limiting member 7 does not have the engaging recess 83, the limiting member 7 can still push the locking part 64 to one side (upper side) in the height direction H by moving from the front end side to the base end side. However, since the limiting member 7 has the engaging recess 83, the distance that the locking part 64 needs to be pushed up and the limiting member 7 needs to pass through is shorter, making it easier for the user to operate.

[0178] like Figure 26 As shown, after the limiting member 7 passes near the locking part 64 of the housing 6, the locking part 64 returns to its initial state.

[0179] Alternatively, the housing 6 of box 5 may also have a clamp 68 for guiding clamp unit 1. Figures 27-29 This is a diagram illustrating the method of using clamp 68 to accommodate clamp unit 1 in box 5.

[0180] like Figure 27 As shown, the clamp 68 can be inserted into the second region 62 through openings 62b on both sides of the width direction W formed in the second region 62. The clamp 68 has an inclined surface 68a at the portion that contacts the clamp unit 1. The inclined surface 68a of the clamp 68 inserted into the second region 62 is inclined relative to the central axis O2, and the normal of the inclined surface 68a faces the front end side.

[0181] like Figure 28 As shown, when the clamp unit 1, which is inserted into the receiving area 6S, is moved towards the base end, the user inserts the clamp 68 into the second area 62. The clamp unit 1, which moves from the front end to the base end, is guided by the inclined surface 68a of the clamp 68, thereby enabling it to move horizontally relative to the central axis O2. As a result, the clamp unit 1 can be received vertically in the box 5.

[0182] According to the box system 100 of this embodiment, the clamp 2 with self-expanding force will not be locked in a closed state by the pressure tube 3, and the clamp unit 1 can be easily loaded into the clamp feeding device 200.

[0183] According to the box system 100 of this embodiment, even without closing the front opening 60b of the box 5 into which the clamp unit 1 is inserted, the clamp unit 1 can be loaded into the clamp guide device 200 by using the locking part 64 to restrict the movement of the limiting member 7 towards the front end and the passage of the clamp unit 1. On the other hand, since the locking part 64 allows the movement of the limiting member 7 towards the base end and the clamp unit 1 to pass through, it is easy to insert the clamp unit 1 into the box 5.

[0184] The first embodiment of the present invention has been described in detail above with reference to the accompanying drawings. However, the specific structure is not limited to this embodiment, and design changes are included without departing from the spirit of the present invention. Furthermore, the constituent elements shown in the above-described embodiment and the variations shown below can be appropriately combined to form a configuration.

[0185] (Variation 1-1)

[0186] For example, in the above embodiment, clamp 68 is used to guide clamp unit 1. However, the guiding pattern of clamp unit 1 is not limited to this. Figure 30This diagram shows a modified example of clamp 68, namely clamp 68B. Clamp 68B has a flat clamp body 68b and a pair of guide members 68c. The pair of guide members 68c are provided in the clamp body 68b and extend in the same direction from the clamp body 68b. When using clamp 68B, the shell body 60 has a through hole 62h for the pair of guide members 68c to pass through, instead of the opening 62b. The through hole 62h communicates with the second region 62.

[0187] Figure 31 This is a sectional view of box 5 with clamp 68B installed.

[0188] A pair of guide members 68c are inserted into the second region 62 through a through hole 62h. The pair of guide members 68c, like the clamp 68, guide the clamp unit 1 that moves from the front end side to the base end side. Similar to the clamp 68, an inclined surface 68a is formed on the pair of guide members 68c.

[0189] (Variations 1-2)

[0190] For example, in the above embodiment, the upper auxiliary member 81 and the lower auxiliary member 82 of the limiting member 7 are formed in a generally flat shape. However, the shape of the limiting member 7 is not limited to this. Figure 32 This is a cross-sectional view of a restriction member 7A, which is a modified example of the restriction member 7. The restriction member 7A has a middle layer member 70, an upper auxiliary member 81A, which is a modified example of an upper auxiliary member 81, and a lower auxiliary member 82A, which is a modified example of a lower auxiliary member 82.

[0191] When viewed from the main view along the length direction L, a centrally projecting slope 81s in the width direction W is formed on the side of the lower auxiliary member 82A of the upper auxiliary member 81A. Furthermore, a centrally projecting slope 82s in the width direction W is formed on the side of the upper auxiliary member 81A of the lower auxiliary member 82A.

[0192] Figure 33 This is a cross-sectional view of the limiting member 7A disposed in the second region 62 of the housing 6.

[0193] Since the upper auxiliary component 81A and the lower auxiliary component 82A have slopes 81s and 82s formed, the pair of arms 21 will not snag and can be easily opened.

[0194] The thickness h in the height direction H of the guide portion 623 is shorter than the thickness t1 in the height direction H of the end of the upper auxiliary member 81A in the width direction W and the thickness t2 in the height direction H of the end of the lower auxiliary member 82A in the width direction W. Therefore, the pair of arms 21 that are in the open state in the second region 62 do not hook onto the guide portion 623.

[0195] (Variations 1-3)

[0196] For example, in the above embodiment, the box 5 houses the clamping unit 1. However, different types of clamping units may also be housed in the box 5. Figure 34 This is a diagram showing a box 5 containing a clamp unit 1a. Figure 35 This is a diagram showing a box 5 containing clamp unit 1b. The clamp units 1a and 1b differ from clamp unit 1 in, for example, the shape of a pair of arms 21.

[0197] Clamping unit 1a and clamping unit 1b are different colors. Furthermore, the housing 6 is made of a transparent resin material. Therefore, it is easy for the user to identify the type of clamping unit housed in the box 5.

[0198] Figure 36 This is a diagram showing a box 5 containing a restrictive member 7a. Figure 37 This diagram shows the box 5 containing the limiting member 7b. Limiting members 7a and 7b are different colors compared to limiting member 7. Limiting member 7 can also be a different color corresponding to the type of clamping unit, just like limiting members 7a and 7b. In this case, since the housing 6 is made of a transparent resin material, the user can easily determine the type of clamping unit contained in the box 5.

[0199] Figure 38 This is a diagram showing box 5, which is packaged in packaging box 110.

[0200] Figure 38 The clamp unit 1 shown is packaged in a box 5 within a packaging box 110. The packaging box 110 is made of a transparent resin material. Even when packaged in the packaging box 110, the user can identify the type of clamp unit by having a different color corresponding to the type of clamp unit, just like the limiting member 7a.

[0201] (Second Implementation)

[0202] Reference Figures 39-46 The second embodiment of the present invention will be described below. In the following description, the same reference numerals will be used for structures that are common to the structures already described, and repeated descriptions will be omitted. The structure of the box 5 in the box system 100B of the second embodiment differs from that in the box system 100 of the first embodiment.

[0203] Figure 39 This is a 3D view of the box system 100B.

[0204] The box system 100B includes a box 5B with a clamping unit 1 and a storage clamping unit 1.

[0205] Figure 40 This is a 3D view of the casing 6B.

[0206] Box 5B has a shell 6B and a limiting member 7B. Box 5B has a length of about 50mm in the longitudinal direction L, a width of about 10mm to 20mm, and a thickness of about 5mm, forming a size that is easy to hold.

[0207] Similar to the first embodiment, one of the two directions perpendicular to and mutually perpendicular to the length direction L of the box 5B is designated as the "width direction W", and the other direction is designated as the "height direction H". Furthermore, the surface parallel to both the length direction L and the width direction W is designated as the "horizontal plane HP". The surface parallel to both the length direction L and the height direction H is designated as the "vertical plane VP". Additionally, in the box 5B housing the clamping unit 1, the side of the pair of arms 21 is designated as the front end side of the box 5B, and the side of the connecting member 4 is designated as the base end side of the box 5B.

[0208] The housing 6B has a housing body 60B, a clamping part 65, and a sheath connecting part 66. The housing 6B is formed using the same material and method as the housing 6 of the first embodiment.

[0209] The shell body 60B is formed in a rectangular box shape. The length W in the width direction of the shell body 60B is longer than the length H in the height direction of the shell body 60B.

[0210] A receiving area 6SB is formed in the shell body 60B to accommodate the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The receiving area 6SB has a first region 61B, a second region 62B, and a closing portion 63. The first region 61B, the second region 62B, and the closing portion 63 are arranged from the front end toward the base end in the longitudinal direction L. The first region 61B, the second region 62B, and the closing portion 63 are formed as an internal space that is symmetrical about the vertical plane VP with respect to the central axis O2 of the longitudinal direction L of the containing box 5B.

[0211] Figure 41 From Figure 40 The arrows shown indicate the direction of observation in the front view of housing 6B.

[0212] The clamping unit 1 is received in the receiving area 6SB through a front opening 60b formed on the front end side of the receiving area 6SB of the housing body 60B. Recessed guide grooves 60g are provided on both sides of the width direction W of the front opening 60b.

[0213] The guide groove 60g is a concave groove into which a pair of arms 21 enter. The pair of arms 21 are smoothly inserted into the first region 61B by means of the guide groove 60g. The guide groove 60g has a guide surface 60m and two side surfaces 60s. The two side surfaces 60s are formed on both sides of the guide surface 60m in the height direction H.

[0214] The guide surface 60m is a plane inclined relative to the vertical plane VP. The normal of the guide surface 60m points towards the front end side in the length direction L. The guide surface 60m is the surface that guides the pair of arms 21 inserted into the first region 61B, making them gradually close.

[0215] The side 60s is a plane inclined relative to the horizontal plane HP. For example... Figure 41 As shown, in the main view viewed from the length direction L, the two side surfaces 60s form a slope that extends further towards the central axis O2. Side surfaces 60s are surfaces that guide a pair of arms 21 inserted into the first region 61B so that they are parallel to the horizontal plane HP.

[0216] The first region 61B is an internal space that accommodates the clamp unit 1 in a manner that allows it to move in the longitudinal direction L. The first region 61B is connected to the second region 62B. The first region 61B has a locking part 64 and a second locking part 69.

[0217] The second locking part 69 is formed on the front end side of the first region 61B and on the other side (lower side) in the height direction H. The second locking part 69 is formed with the same shape as the locking part 64. The locking part 64 and the second locking part 69 are formed at a position symmetrical to the central axis O2 in the length direction L of the receiving region 6SB.

[0218] The second region 62B is an internal space that accommodates the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The length of the second region 62B in the longitudinal direction L is shorter than the length of the first region 61B in the longitudinal direction L. The second region 62B communicates with the closing part 63. The second region 62B is the same as the second region 62 in the first embodiment, except that it does not have the guide part 623.

[0219] Figure 42 This is an exploded view of the shell body 60B.

[0220] The shell body 60B is formed by joining a first shell member 601 and a second shell member 602 together. The first shell member 601 and the second shell member 602 are of the same shape. Figure 41 As shown, the first housing member 601 and the second housing member 602 are not symmetrical with respect to the horizontal plane HP containing the central axis O2, but are symmetrical with respect to the central axis O2.

[0221] The joint portion where the first housing member 601 and the second housing member 602 meet typically has irregularities. However, this joint portion is not formed at the point where the guide groove 60g contacts the pair of arms 21 of the first region 61B. Therefore, the pair of arms 21 are smoothly inserted into the first region 61B without being affected by the irregularities formed at the joint portion.

[0222] Figure 43 This is a three-dimensional view of the limiting component 7B.

[0223] The limiting member 7B, together with the clamping unit 1, is movably housed in the first region 61B and the second region 62B. The limiting member 7B is formed in a shape symmetrical with respect to the vertical plane VP of the central axis O3 in the length direction L containing the limiting member 7B. The limiting member 7B has a middle layer member 70 and an auxiliary member 8B.

[0224] The auxiliary member 8B adjusts the position of the limiting member 7B in the height direction H so that the protrusion 72 is held by a pair of arms 21. The auxiliary member 8B has an upper auxiliary member 81 located on one side (upper side) in the height direction H and a lower auxiliary member 82B located on the other side (lower side) in the height direction H. The middle member 70 is clamped by the upper auxiliary member 81 and the lower auxiliary member 82B in the height direction H. Alternatively, the auxiliary member 8B is not required when it is not necessary to adjust the position of the limiting member 7B in the height direction.

[0225] A second engaging recess 87 is formed on the opposite side (lower side) of the lower auxiliary member 82B in the height direction H. The second engaging recess 87 is a recess that engages with the second locking portion 69. The second engaging recess 87 is formed with the same shape as the engaging recess 83. The engaging recess 83 and the second engaging recess 87 are formed in positions symmetrical with respect to the central axis O3. In addition, if the auxiliary member 8B is not required, the second engaging recess 87 only needs to be provided in at least a portion of the front end portion 71, the protrusion 72, and the slope portion 73.

[0226] [Method for loading fixture unit 1]

[0227] The filling method of the fixture unit 1 is the same as that of the first embodiment, except for the following points.

[0228] When the clamp unit 1 is loaded into the clamp guide device 200 using the box 5B, the engaging recess 83 of the limiting member 7B abuts against and engages with the locking part 64. Furthermore, the second engaging recess 87 of the limiting member 7B abuts against and engages with the second locking part 69. As a result, the clamp unit 1 cannot advance towards the front end from this position. That is, the locking part 64 and the second locking part 69 restrict the passage of the clamp unit 1 moving towards the front end. The advancing arrow hook 231 is clamped by the elastic arm 44 of the connecting member 4 of the clamp unit 1 and connected to the connecting member 4. Because the limiting member 7B abuts against and engages with the locking part 64 and the second locking part 69, the box 5B can more reliably restrict the passage of the clamp unit 1 moving towards the front end.

[0229] [Method for accommodating fixture unit 1]

[0230] Next, the method of accommodating the fixture unit 1 in the box 5B will be described. Figures 44-46 This is a diagram illustrating the method of accommodating the fixture unit 1 in the box 5B.

[0231] like Figure 44 As shown, the user inserts a portion of the clamp unit 1, without the restraining member 7B, into the receiving area 6S of the box 5 through the front opening 60b. Then, the user moves the pair of arms 21 along the guide groove 60g.

[0232] like Figure 45 As shown, the user pushes the limiting member 7B towards the base end. The pushed-in limiting member 7B causes the pair of arms 21 to move towards the base end. The pair of arms 21 are guided by the guide surface 60m of the guide groove 60g (see reference). Figure 41 The pair of arms 21 are guided into a gradually closing state even when tilted relative to the horizontal plane HP by the side 60s of the guide groove 60g (see reference). Figure 41 The guide is directed to be parallel to the horizontal plane HP.

[0233] like Figure 46 As shown, by pushing the limiting member 7B further towards the base end, the limiting member 7B, which is held in a state of gripping the pair of arms 21, can be inserted into the first region 61B. Compared with the first embodiment, the user does not need to use their hands or the like to close the pair of arms 21 to hold the limiting member 7 in the pair of arms 21, thus eliminating the labor and time required. The method of receiving the clamp unit 1 thereafter is the same as in the first embodiment.

[0234] According to the box system 100B of this embodiment, the clamp 2 with self-expanding force will not be locked in a closed state by the pressure tube 3, and the clamp unit 1 can be easily loaded into the clamp feeding device 200.

[0235] According to the box system 100B of this embodiment, even without closing the front opening 60b of the box 5B into which the clamp unit 1 is inserted, the clamp unit 1 can be loaded into the clamp guide device 200 by using the locking part 64 and the second locking part 69 to restrict the movement of the limiting member 7 towards the front end and the passage of the clamp unit 1. On the other hand, since the locking part 64 and the second locking part 69 allow the movement of the limiting member 7 towards the base end and the clamp unit 1 to pass through, it is easy to insert the clamp unit 1 into the box 5B.

[0236] The second embodiment of the present invention has been described in detail above with reference to the accompanying drawings. However, the specific structure is not limited to this embodiment, and design changes are included without departing from the spirit of the present invention. Furthermore, the constituent elements shown in the above-described embodiment and the variations shown below can be appropriately combined to form a configuration.

[0237] (Third Implementation)

[0238] Reference Figures 47-54The third embodiment of the present invention will be described below. In the following description, the same reference numerals will be used for structures that are common to the structures already described, and repeated descriptions will be omitted. The structure of the locking part 64 in the box system 100C of the third embodiment differs from that in the box system 100 of the first embodiment.

[0239] Figure 47 This is a 3D view of the box system 100C.

[0240] The box system 100C has a box 5C with a clamping unit 1 and a storage clamping unit 1.

[0241] Figure 48 This is a 3D view of the casing 6C.

[0242] Box 5C has a shell 6C and a limiting member 7C. Box 5C has a length of about 50mm in the longitudinal direction L, a width of about 10mm to 20mm, and a thickness of about 5mm, forming a size that is easy to hold.

[0243] Similar to the first embodiment, one of the two directions perpendicular to and mutually perpendicular to the length direction L of the box 5C is designated as the "width direction W", and the other direction is designated as the "height direction H". Furthermore, the surface parallel to both the length direction L and the width direction W is designated as the "horizontal plane HP". The surface parallel to both the length direction L and the height direction H is designated as the "vertical plane VP". Additionally, in the box 5C housing the clamping unit 1, the side of the pair of arms 21 is designated as the front end side of the box 5C, and the side of the connecting member 4 is designated as the base end side of the box 5C.

[0244] The housing 6C has a housing body 60C, a clamping part 65, and a sheath connecting part 66. The housing 6C is formed using the same material and method as the housing 6 of the first embodiment.

[0245] The shell body 60C is formed in a rectangular box shape. The length W in the width direction of the shell body 60C is longer than the length H in the height direction of the shell body 60C.

[0246] A receiving area 6SC is formed in the shell body 60C to accommodate the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The receiving area 6SC has a first region 61C, a second region 62B, and a closing portion 63. The first region 61C, the second region 62B, and the closing portion 63 are arranged from the front end toward the base end in the longitudinal direction L. The first region 61C, the second region 62B, and the closing portion 63 are formed as an internal space that is symmetrical about the vertical plane VP with respect to the central axis O2 of the longitudinal direction L of the containing box 5C.

[0247] Figure 49 This is a cross-sectional view of the housing 6C.

[0248] The first region 61C is an internal space that accommodates the clamping unit 1 in a manner that allows it to move in the longitudinal direction L. The first region 61C communicates with the second region 62B. The first region 61C has a locking part 64C.

[0249] The first region 61C has a front end region 611, an enlarged diameter region 612, a slope region 613, and a base end region 614. The front end region 611, the enlarged diameter region 612, the slope region 613, and the base end region 614 are arranged from the front end toward the base end in the length direction L.

[0250] The front end region 611 and the base end region 614 are the same as the first region 61 in the first embodiment, which is the internal space of the length W1 in the width direction W.

[0251] The expanded diameter region 612 is a region that is longer in the width direction W compared to the front end region 611 and the base end region 614. One side of the expanded diameter region 612 in the width direction W is longer by a length W5 than both the front end region 611 and the base end region 614. The other side of the expanded diameter region 612 in the width direction W is also longer by a length W5 than both the front end region 611 and the base end region 614. The length (W1 + 2 * W5) of the expanded diameter region 612 in the width direction W is less than the opening width W3 of the pair of arms 21 in the open state.

[0252] Slope region 613 is a slope shape that decreases in length W in the width direction from the front end towards the base end. The length W in the width direction of the front end of slope region 613 is equal to the length W in the width direction of the widening region 612 (W1 + 2 * W5). The length W in the width direction of the base end of slope region 613 is equal to the length W in the width direction of the base end region 614 (W1).

[0253] The locking portion 64C is a step formed in the width direction W between the front end region 611 and the diameter expansion region 612. The locking portion 64C is formed on both sides in the width direction W. Alternatively, the locking portion 64C may be provided only on one side in the width direction W.

[0254] The limiting member 7C, together with the clamping unit 1, is movably accommodated in the first region 61C and the second region 62B. The limiting member 7C is the same as the limiting member 7 in the first embodiment, except that it does not have the engaging recess 83.

[0255] [Method for accommodating fixture unit 1]

[0256] Next, the method of accommodating the fixture unit 1 in the box 5C will be described. Figures 50-51 This is a diagram illustrating the method of accommodating the fixture unit 1 in the box 5C.

[0257] The user closes the pair of arms 21 using their hands, etc., so that the restraining member 7 is held in place by the pair of arms 21. Then, as... Figure 50 As shown, the user inserts the clamp unit 1, which holds the limiting member 7C, into the receiving area 6SC of the box 5C through the front opening 60b. In the front area 611, the length W6 (holding amount) of the portion of the first arm 211 that holds the limiting member 7C in the width direction is longer than the length W5.

[0258] like Figure 51 As shown, the user pushes the limiting member 7 towards the base end, thereby moving the clamping unit 1 towards the base end. The locking part 64C allows the limiting member 7C and the clamping unit 1, which are moving towards the base end, to pass through. If the limiting member 7C moves from the front end region 611 to the widening region 612, the length of the width W of the internal space increases, and therefore the pair of arms 21 open slightly. However, since the length W6 is longer than the length W5, even if the pair of arms 21 expands slightly, the pair of arms 21 maintains the state of holding the limiting member 7C.

[0259] [Method for loading fixture unit 1]

[0260] Next, the method of loading the fixture unit 1 into the fixture guide device 200 using the box 5C will be described. Figures 52-53 This is a diagram illustrating the method of loading the fixture unit 1 into the fixture guide device 200 using the box 5C.

[0261] The user inserts the sheath 220 of the clamp guide device 200 into the receiving area 6SC of the housing 6C through the base opening 67 of the sheath connection portion 66. The user uses the clamping portion 65 to press the sheath 220, fixing the sheath 220 relative to the housing 6C.

[0262] like Figure 52 As shown, the user advances the operating line 230 relative to the sheath 220 by operating the operating part 240, thereby advancing the arrow hook 231. The arrow hook 231 advances the connecting member 4, thereby restricting the advance of the member 7C and the clamp unit 1. By restricting the movement of the member 7C from the base end side to the front end side, a pair of arms 21 abut against and engage with the locking part 64C. As a result, the clamp unit 1 cannot advance towards the front end from this position. That is, the locking part 64C restricts the passage of the clamp unit 1 moving towards the front end. The advancing arrow hook 231 is clamped by the elastic arm 44 of the connecting member 4 of the clamp unit 1 and connected to the connecting member 4.

[0263] The user pulls the operating line 230. The clamp 2 of the clamp unit 1 is pulled towards the base end by the connecting member 4 connected to the arrow hook 231. Figure 53As shown, if the limiting member 7C moves from the widening region 612 to the slope region 613, the length of the width W of the internal space becomes shorter, thus the pair of arms 21 slightly close. If the limiting member 7C moves from the slope region 613 to the base region 614, the pair of arms 21 firmly hold the limiting member 7C. The subsequent filling method of the clamping unit 1 is the same as in the first embodiment.

[0264] According to the box system 100C of this embodiment, the clamp 2 with self-expanding force will not be locked in a closed state by the pressure tube 3, and the clamp unit 1 can be easily loaded into the clamp feeding device 200.

[0265] According to the box system 100C of this embodiment, even without closing the front opening 60b of the box 5C into which the clamp unit 1 is inserted, the clamp unit 1 can be loaded into the clamp guide device 200 by using the locking part 64C to restrict the movement of the limiting member 7C towards the front end and the passage of the clamp unit 1. On the other hand, since the locking part 64C allows the movement of the limiting member 7C towards the base end and the clamp unit 1 to pass through, it is easy to insert the clamp unit 1 into the box 5C.

[0266] The third embodiment of the present invention has been described in detail above with reference to the accompanying drawings. However, the specific structure is not limited to this embodiment, and design changes are included without departing from the spirit of the present invention. Furthermore, the constituent elements shown in the above-described embodiment and the variations shown below can be appropriately combined to form a configuration.

[0267] (Variation 3-1)

[0268] For example, in the above embodiment, box 5C has a limiting member 7C, but the limiting member 7C is not necessarily required. Figure 54 This is a diagram showing a housing 6C that houses the clamp unit 1 without using the limiting member 7C.

[0269] With the clamping unit 1 housed in the housing 6C, the user moves the clamping unit 1 towards the base end by pushing it in. A pair of arms 21 inserted into the first region 61C abut against the housing body 60C in the opening / closing direction P.

[0270] When loading the clamp unit 1 into the clamp feeding device 200, the user advances the arrow hook 231. The arrow hook 231 advances the connecting member 4, thereby advancing the clamp unit 1. As the clamp unit 1 moves from the base end side to the front end side, a pair of arms 21 with self-expanding force abut against and engage with the locking part 64C. As a result, the clamp unit 1 cannot advance further towards the front end from this position. That is, the locking part 64 restricts the passage of the clamp unit 1 moving towards the front end. The advancing arrow hook 231 is clamped by the elastic arm 44 of the connecting member 4 of the clamp unit 1 and connected to the connecting member 4. The subsequent loading method of the clamp unit 1 is the same as in the first embodiment.

[0271] (Variation 3-2)

[0272] In the above embodiment, the clamp 2 has a first arm 211 and a second arm 212, but the form of the clamp 2 is not limited to this. The clamp 2 can have multiple arms that can be opened and closed, for example, it can also have four arms.

[0273] Industrial availability

[0274] This invention can be applied to boxes, etc., that house clamping units.
