DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] It should be understood that the terms "proximal" and "distal" used herein are relative to the clinician manipulating the ureteral stent system. The term "proximal" refers to the portion close to the clinician, and the term "distal" refers to the portion away from the clinician. The proximal end of a component refers to the end relatively close to the clinician, and the distal end refers to the end relatively far from the clinician. However, the ureteral stent system can be used in many directions and positions, so these terms expressing relative positional relationships are not limiting and absolute.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms such as "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movably connection, or an integral body; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements such as abutment. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. It should be noted that when there are qualifiers before "connected" and "connection", they have the meaning defined by the corresponding qualifiers, and only exclude situations that obviously need to be excluded, and do not exclude other possible situations. For example, "detachably connected" refers to a detachable connection, and does not include integration, but movable connection, etc. are not excluded.

[0034] The first direction, the second direction and the third direction of the present invention are perpendicular to each other. Figure 7 For reference, the first direction is the up and down direction, and is the direction from bottom to top. The second direction is the direction perpendicular to the paper surface, and is the direction toward the paper surface. The third direction is the left and right direction, and is the direction from left to right.

[0035] See also Figure 7 The present invention provides a ureteral stent system, which includes a contained object and a containing device. The contained object in the present invention is a ureteral stent 6.

[0036] The ureteral stent 6 includes a deflated state and an expanded state. Figure 5 The contracted state means that the ureteral stent 6 has not expanded or deformed, and the ureteral stent 6 is generally cylindrical. Figure 6 The expansion state means that the ureteral stent 6 has expanded and deformed, and at least one end thereof is deformed into a cone. The cone-shaped end can limit the sliding of the ureteral stent 6 in the ureter, so that the ureteral stent 6 can be stably maintained at the stenosis or obstruction of the ureter. The ureteral stent 6 is left in the stenosis or obstruction of the ureter, and the ureteral stent 6 can support and drain the stenosis or obstruction of the ureter to maintain the normal flow of urine.

[0037] The material of the ureteral stent 6 is a shape memory alloy, such as nickel-titanium shape memory alloy. In the initial state, it maintains a contracted shape, and expands and deforms to an expanded shape when heated.

[0038] In the process of preparing the ureteral stent 6, a strip of shape memory alloy is used to wind the ureteral stent 6 in an expanded form and placed at high temperature for finalization. In this process, the ureteral stent 6 can be wound into a single-end expansion shape or a double-end expansion shape as required. The single-end expansion shape is to wind one end of the ureteral stent 6 into an expanded cone, and the double-end expansion shape is to wind both ends of the ureteral stent 6 into an expanded cone. Specifically, the ureteral stent 6 includes two end regions 610 and a middle region 620 located between the two end regions 610. When winding, the middle region 620 is generally wound into a cylindrical shape, and one or two end regions 610 are wound into a cone, and the diameter of the cone-shaped end region 610 gradually increases from the middle region 620 along its extension direction.

[0039] After the expanded ureteral stent 6 is placed at high temperature for shaping, it is taken out and cooled at low temperature, and then the ureteral stent 6 is rewound into a compact shape and then packaged.

[0040] When the ureteral stent 6 is used, the ureteral stent 6 is placed in the ureter of the human body and then heated, and at least one end of the ureteral stent 6 expands and deforms, so that the ureteral stent 6 is transformed into an expanded state. The ureteral stent 6 can be heated by injecting saline into the ureter, and the temperature of the saline can be set according to the temperature required for the expansion and deformation of the ureteral stent 6, but it must be kept within the safety range of the human body.

[0041] If the ureteral stent 6 is converted to an expanded state before use, it cannot be placed in the ureter of the human body. Therefore, the ureteral stent 6 needs to be kept in a contracted state before use, and after being placed in the human ureter, it is heated to expand and deform to the expanded state.

[0042] refer to Figure 1-4 , Figure 7 and Fig. 9 The ureteral stent system of the present invention further includes a delivery device. The delivery device includes a core shaft 7 and a support tube 8. The delivery device has a first state and a second state. In the first state, the ureteral stent 6 is sleeved on the support tube 8, and the core shaft 7 is passed through the support tube 8, so that the support tube 8 maintains its shape to support the ureteral stent 6, and the core shaft 7 maintains its position relative to the support tube 8. In the second state, the core shaft 7 moves relative to the support tube 8 so that the core shaft 7 at least partially detaches from the support tube 8, so that the support tube 8 can be deformed, thereby allowing the ureteral stent 6 to detach from the support tube 8.

[0043] When the support tube 8 maintains its shape, the support tube 8 can support the ureteral stent 6 to limit the movement of the ureteral stent 6 and prevent the ureteral stent 6 from falling off the support tube 8. Figure 1-3The distal end of the support tube 8 has a stop unit. In the first state, the core shaft 7 passes through the support tube 8 and the stop unit to open the stop unit, so that the stop unit abuts against the distal end of the ureteral stent 6, thereby preventing the ureteral stent 6 from detaching from the support tube 8. The support tube 8 maintains its shape, that is, the stop unit at the distal end of the support tube 8 is restricted from moving by the core shaft 7 and remains abutted against the distal end of the ureteral stent 6.

[0044] refer to Figure 1-3 The stop unit includes a first stop arm 810 and a second stop arm 820, and the first stop arm 810 and the second stop arm 820 are both made of elastically deformable plastic material. The first stop arm 810 has a first stop portion 8101, and the second stop arm 820 has a second stop portion. In the first state, the core shaft 7 is arranged in the support tube 8 and penetrates into the stop unit, that is, the core shaft 7 penetrates between the first stop arm 810 and the second stop arm 820, and the core shaft 7 constrains the first stop arm 810 and the second stop arm 820 to limit the lateral deflection of the first stop arm 810 and the second stop arm 820, so that the support tube 8 maintains its shape, so that the first stop portion 8101 of the first stop arm 810 and the second stop portion of the second stop arm 820 are both in contact with the distal end of the ureteral stent 6, thereby preventing the ureteral stent 6 from being separated from the support tube 8.

[0045] In the second state, the core shaft 7 moves relative to the support tube 8 so that the core shaft 7 at least partially detaches from the support tube 8, so that the support tube 8 can be deformed. Specifically, the core shaft 7 moves relative to the support tube 8 so that the core shaft 7 detaches from the stop unit at the distal end of the support tube 8, that is, the core shaft 7 detaches from between the first stop arm 810 and the second stop arm 820, thereby releasing the restriction on the first stop arm 810 and the second stop arm 820. When the ureteral stent 6 moves toward the distal end of the support tube 8, the first stop arm 810 and the second stop arm 820 are moved toward each other by their own elastic lateral deflection, and the support tube 8 is deformed, so that the ureteral stent 6 can detach from the support tube 8 from the stop unit at the distal end of the support tube 8.

[0046] The delivery device further includes a limiting tube 10. In the first state, the limiting tube 10 is sleeved on the support tube 8, the distal end of the support tube 8 extends from the distal end of the limiting tube 10, and the ureteral stent 6 is sleeved on the support tube 8 and located between the stop unit at the distal end of the support tube 8 and the distal end of the limiting tube 10. The stop unit limits the distal end of the ureteral stent 6, and the distal end of the limiting tube 10 limits the proximal end of the ureteral stent 6.

[0047] refer to Figure 1-4The proximal end of the limiting tube 10 is provided with a first connecting member 11, the proximal end of the support tube 8 passes through the limiting tube 10 and the first connecting member 11, and the proximal end of the support tube 8 is provided with a second connecting member 9. The first connecting member 11 and the second connecting member 9 are detachably connected, the proximal end of the core shaft 7 passes through the support tube 8 and the second connecting member 9, and the proximal end of the core shaft 7 extends from the second connecting member 9.

[0048] Optionally, the first connecting member 11 is threadedly connected to the second connecting member 9. Specifically, the proximal end of the first connecting member 11 has a first connecting portion 1101, and the distal end of the second connecting member 9 has a second connecting portion 901. The first connecting portion 1101 is inserted into the second connecting portion 901 and threadedly connected to the second connecting portion 901.

[0049] When placing the ureteral stent 6 in the ureter of the human body, the distal region of the delivery device is placed in the ureter so that the ureteral stent 6 is located at the narrow or blocked part of the ureter, while the proximal end of the core shaft 7, the first connector 11, and the second connector 9 are all located outside the human body. The core shaft 7 is pulled from the proximal end of the core shaft 7 so that the core shaft 7 moves proximally to pull the core shaft 7 out of the support tube 8, so that the core shaft 7 is separated from the stop unit at the distal end of the support tube 8, and the restriction on the stop unit is released. The second connector 9 is then separated from the first connector 11, and the second connector 9 is pulled proximally so that the support tube 8 moves proximally relative to the limiting tube 10 until it is separated from the limiting tube 10. In this process, if the ureteral stent 6 is a single-end expansion type, the distal end of the ureteral stent 6 expands into a cone shape, and the limiting tube 11 is closed. The distal end of 10 abuts against the proximal end of the ureteral stent 6 to prevent the ureteral stent 6 from being moved by the support tube 8, so that the ureteral stent 6 can be stably retained in the obstruction or stenosis. If the ureteral stent 6 is a double-end expansion shape, that is, both ends of the ureteral stent 6 are expanded into a cone, and the two cone ends are supported inside the ureter, the ureteral stent 6 can be stably retained in the obstruction or stenosis in the ureter. Therefore, in the process of pulling out the support tube 8, the ureteral stent 6 will not move. After the support tube 8 is pulled out of the body, the first connecting member 11 is manipulated to pull the limiting tube 10 out of the body. In this way, the delivery device is pulled out of the body.

[0050] refer to Figure 7 The ureteral stent system of the present invention further includes a receiving device. Before the ureteral stent 6 is used, the conveying device maintains a first state, the supporting tube 8 supports the ureteral stent 6, and the ureteral stent 6 is received in the receiving device.

[0051] The accommodating device comprises a first accommodating member 1, a second accommodating member 2 and a locking mechanism. The first accommodating member 1 and the second accommodating member 2 both have an accommodating portion 3. The first accommodating member 1 and the second accommodating member 2 are connected via the locking mechanism.

[0052] The locking mechanism has a locked state and an unlocked state, and the locked state and the unlocked state of the locking mechanism are switchable.

[0053] In the locked state, the first accommodating member 1 and the second accommodating member 2 maintain relative positions, so that a fixed space is formed between the accommodating portions 3 of the first accommodating member 1 and the second accommodating member 2 to accommodate the accommodated object. In the unlocked state, the first accommodating member 1 and the second accommodating member 2 can be separated. The material of the accommodated object is a shape memory alloy. As described above, the accommodated object of the present invention is a ureteral stent 6.

[0054] Maintaining the relative position means that there is no relative movement between the first accommodating component 1 and the second accommodating component 2, one of the first accommodating component 1 and the second accommodating component 2 will not be displaced relative to the other, and the relative position of the first accommodating component 1 and the second accommodating component 2 remains unchanged.

[0055] The fixed space is a storage space with a constant volume. The shape of the fixed space is adapted to the outer diameter of the ureteral stent 6, so that when the ureteral stent 6 is placed in the fixed space, the storage portion 3 of the first storage component 1 and the storage portion 3 of the second storage component 2 are both in contact with the surface of the ureteral stent 6. When the ureteral stent 6 has a tendency to expand, the storage portion 3 is in contact with the surface of the ureteral stent 6, which limits the expansion and deformation of the ureteral stent 6, so that the ureteral stent 6 can maintain a compact shape. When the locking mechanism is in the unlocked state, the first storage component 1 and the second storage component 2 can be separated, so that the ureteral stent 6 can be taken out for use.

[0056] In summary, the first accommodating component 1 and the second accommodating component 2 of the accommodating device of the present invention are connected via a locking mechanism. When the locking mechanism is in a locked state, the first accommodating component 1 and the second accommodating component 2 maintain a relative position, so that a fixed space is formed between the accommodating portions 3 of the first accommodating component 1 and the second accommodating component 2 to accommodate the ureteral stent, which can prevent the ureteral stent 6 from expanding and deforming before use, and the locking mechanism has an unlocked state, which is convenient for disassembling the first accommodating component 2 and the second accommodating component 2 to remove the ureteral stent 6.

[0057] The locking mechanism of the present invention includes a clamping member 110 and a coupling structure. The first accommodating member is provided with the clamping member 110, and the second accommodating member is provided with the coupling structure. In the locked state, the clamping member 110 of the first accommodating member 1 is engaged with the coupling structure of the second accommodating member 2, so that the first accommodating member 1 and the second accommodating member 2 are relatively locked and maintained in relative position.

[0058] The engaging member 110 is released from the engaging structure, so that the locking mechanism is switched to the unlocked state, that is, the first accommodating member 1 and the second accommodating member 2 can be separated. The unlocking process of the locking mechanism has no safety hazard and will not cause harm to medical staff.

[0059] The clamping member 110 is elastic. By applying force to the clamping member 110 , the clamping member 110 can be engaged with the joint structure, or the clamping member 110 can be separated from the joint structure.

[0060] Optionally, the receiving portion 3 of the present invention is a groove. When the ureteral stent 6 is placed in a fixed space, the inner wall of each receiving portion 3 is in contact with the surface of the ureteral stent 6 .

[0061] In the first embodiment of the present invention, the locking mechanism includes a locking unit, and the locking unit includes a clamping member 110 and a coupling structure. Fig.10 and Fig.13 The engaging structure includes an inserting portion 210 and a butting portion 212, and the inserting portion 210 has an opening 211. In the locked state, the clamping member 110 penetrates the inserting portion 210 and extends from the opening 211 to maintain abutment with the butting portion 212, so that the clamping member 110 is engaged with the engaging structure. Maintaining abutment means that the clamping member and the butting portion can be stably abutted and will not be disengaged, thereby enabling the clamping member 110 to engage with the engaging structure.

[0062] refer to Figure 11-12 The clamping member 110 has a first clamping portion 111 and a second clamping portion 112 connected to each other. Figure 8 Combined with Fig.10 In the locked state, the first clamping portion 111 penetrates the plug-in portion 210, and the second clamping portion 112 extends from the opening 211 and maintains contact with the abutting portion 212, so that the clamping member 110 is engaged with the engagement structure. Specifically, the clamping member 110 and the abutting portion 212 maintain contact, specifically, the second clamping portion 112 of the clamping member 110 maintains contact with the abutting portion 212.

[0063] refer to Figure 7-9 When the locking mechanism is in the locked state, the first accommodating member 1 and the second accommodating member 2 are stacked, and the first clamping portion 111 of the first accommodating member 1 penetrates into the plug-in portion 210 of the second accommodating member 2 and abuts against the inner wall of the plug-in portion 210, thereby limiting the relative movement of the first accommodating member 1 and the second accommodating member 2 in the abutting direction of the first clamping portion 111 and the plug-in portion 210.

[0064] The second clamping portion 112 extends out from the opening portion 211 and abuts against the supporting portion 212, thereby limiting the relative movement of the first accommodating member 1 and the second accommodating member 2 in the abutting direction between the second clamping portion 112 and the supporting portion 212, and limiting the first clamping portion 111 from being separated from the plug-in portion 210, so that the clamping member 110 and the engaging structure are stably engaged.

[0065] refer to Figure 11-12, the second clamping portion 112 protrudes relative to the outer wall of the first clamping portion 111. The first clamping portion 111 is elastic. Specifically, the material of the first clamping portion 111 is an elastically deformable plastic material. In response to the force applied to the clamping member, the first clamping portion 111 is elastically deformed so that the second clamping portion 112 abuts against the abutting portion 212. In this embodiment, in the locked state, the deformation of the first clamping portion 111 is limited, so that the second clamping portion 112 and the abutting portion 212 remain in abutment and will not be disengaged, so that the locking mechanism remains in the locked state.

[0066] refer to Figure 9-10 In this embodiment, the plug-in portion 210 is a hole structure, and the plug-in portion 210 penetrates the second accommodating member 2 to form an opening portion 211 in the second accommodating member 2. Specifically, the plug-in portion 210 generally penetrates two opposite walls of the second accommodating member 2 along the first direction, and extends from one of the walls to form the opening portion 211.

[0067] refer to Fig.10 and Fig.13 In this embodiment, a supporting portion 212 is formed at the edge of the opening 211 .

[0068] In the locked state, the first accommodating member 1 and the second accommodating member 2 are arranged opposite to each other along the first direction, the first clamping portion 111 of the clamping member 110 penetrates into the plug-in portion 210 along the first direction, the first clamping portion 111 is located in the plug-in portion 210, the second clamping portion 112 extends from the plug-in portion 210 through the opening portion 211, the first clamping portion 111 abuts against the plug-in portion 210 along a direction perpendicular to the first direction, and the second clamping portion 112 extends from the opening portion 211 and abuts against the abutting portion 212 along the first direction.

[0069] When the locking mechanism is in the locked state, since the clamping member 110 penetrates into the plug-in portion 210 along the first direction, the first clamping portion 111 abuts against the plug-in portion 210 along the direction perpendicular to the first direction, which limits the relative movement of the first accommodating member 1 and the second accommodating member 2 along the direction perpendicular to the first direction, so that the first accommodating member 1 and the second accommodating member 2 have no relative movement in the direction perpendicular to the first direction. In other words, the first accommodating member 1 and the second accommodating member 2 have no relative movement on the plane perpendicular to the first direction.

[0070] The second clamping portion 112 of the clamping member 110 abuts against the supporting portion 212 along the first direction, so that the first clamping portion 111 of the clamping member 110 is restricted in the plug-in portion 210 and cannot be separated from the plug-in portion 210 where it is located, and the relative movement of the first accommodating member 1 and the second accommodating member 2 in the first direction is restricted, so that the first accommodating member 1 and the second accommodating member 2 do not have relative movement in the first direction, and the first accommodating member 1 and the second accommodating member 2 can maintain their relative positions.

[0071] In summary, when the locking mechanism is in the locked state, the first clamping portion 111 of the clamping member 110 of this embodiment penetrates into the plug-in portion 210 along the first direction, the first clamping portion 111 and the plug-in portion 210 abut against each other in a direction perpendicular to the first direction, and the second clamping portion 112 of the clamping member 110 abuts against the abutting portion 212 along the first direction, so that the first accommodating member 1 and the second accommodating member 2 maintain a relative position, thereby forming a fixed space between the accommodating portion 3 of the first accommodating member 1 and the accommodating portion 3 of the second accommodating member 2.

[0072] When the ureteral stent 6 is in use, the deformation restriction on the first clamping portion 111 of the clamping member 110 is released, so that the first clamping portion 111 can be deformed, thereby releasing the abutment between the second clamping portion 112 and the abutting portion 212, and separating the first clamping portion 111 from the plug-in portion 210. As a result, the clamping member 110 is released from the engagement structure, and the locking mechanism is switched to the unlocked state, so that the first accommodating member 1 and the second accommodating member 2 can be separated to open the accommodating device and remove the ureteral stent 6.

[0073] When the deformation restriction of the first clamping part 111 of the clamping part 110 is released, the abutment between the second clamping part and the supporting part 212 is no longer stable. When subjected to external force, the second clamping part and the supporting part 212 will be disengaged. At this time, the clamping part 110 and the engaging structure are not in a clamping state, and the locking mechanism is in an unlocked state.

[0074] As described above, the locking mechanism of this embodiment includes a locking unit, and the locking unit includes a coupling structure and a clamping member 110. Figure 8-10 and Fig.13 , the locking unit of this embodiment further includes a locking member 4. In the locked state, the locking member 4 penetrates into the plug-in portion and abuts against the clamping member 110 in the plug-in portion 210 where it is located, so that the clamping member 110 remains in abutment with the abutting portion 212, thereby enabling the clamping member 110 to engage with the engagement structure. Specifically, when the locking member 4 and the clamping member 110 are both inserted into the plug-in portion 210, the locking member 4 abuts against the clamping member 110 to restrict the clamping member 110, so that the first clamping portion 111 of the clamping member 110 cannot be deformed, and the second clamping portion 112 of the clamping member 110 remains in abutment with the abutting portion 212, thereby enabling the clamping member 110 to engage with the engagement structure.

[0075] Specifically, refer to Figure 8When the locking unit is in the locked state, the locking member 4 and the first clamping portion 111 of the clamping member 110 are both inserted into the plug-in portion 210, so that the first clamping portion 111 is in contact with the inner wall of the plug-in portion 210, and the second clamping portion 112 is in contact with the abutting portion 212. Specifically, the space in the plug-in portion 210 can accommodate the locking member 4 and the first clamping portion 111. When the locking member 4 and the first clamping portion 111 are both inserted into the plug-in portion 210, the locking member 4 presses the first clamping portion 111, so that the first clamping portion 111 is close to the inner wall of the plug-in portion 210 and the deformation of the first clamping portion 111 is limited, so that the second clamping portion 112 is in contact with the abutting portion 212. Due to the squeezing of the locking member 4, the first clamping portion 111 cannot move in the plug-in portion 210 along a direction perpendicular to the first direction, and due to the abutment between the second clamping portion 112 and the abutment portion 212, the first clamping portion 111 cannot move along the first direction to disengage from the plug-in portion 210, thereby making the clamping member 110 stably engaged with the coupling structure.

[0076] refer to Fig. 9 After the locking member 4 is removed from the plug-in portion 210, the first clamping portion 111 can be deformed to be able to move relative to the plug-in portion 210 in the plug-in portion 210, and the locking mechanism is switched to the unlocked state. When the first accommodating member 1 and the second accommodating member 2 are separated, the first clamping portion 111 moves in the plug-in portion 210 until the second clamping portion 112 no longer abuts against the abutting portion 212, and the first clamping portion 111 is separated from the plug-in portion 210.

[0077] Each locking unit includes at least two clamping members 110. In the locked state, each clamping member 110 of each locking unit penetrates into the plug-in portion, and the locking member 4 penetrates between the clamping members 110 and abuts against the clamping members 110, so that each clamping member 110 remains in abutment with the abutting portion 212.

[0078] refer to Figure 10-12 In this embodiment, each locking unit includes two clips 110, and the structures of the two clips 110 are substantially the same. Each clip 110 is elastic and can be elastically deformed when subjected to external force. When the locking unit is in a locked state, the locking member 4 and the first clip portion 111 of each clip 110 are inserted into the plug-in portion 210, and the locking member 4 is inserted between the two first clip portions 111, so that the first clip portion 111 of each clip 110 is in contact with the inner wall of the plug-in portion 210 where it is located, and the second clip portion 112 of each clip 110 is in contact with the abutting portion 212.

[0079] In this embodiment, the first accommodating member 1 is connected to the second accommodating member 2 via at least two locking units, and the locking members 4 of at least two locking units are connected. Specifically, the locking mechanism of this embodiment includes multiple locking units, and the first accommodating member 1 is connected to the second accommodating member 2 via multiple locking units, further improving the connection stability between the first accommodating member 1 and the second accommodating member 2. The locking members 4 of at least two locking units are connected, so that when the accommodating device is affected by external factors and causes one of the locking members 4 to have a tendency to be separated from the plug-in portion 210 where it is located, the locking member 4 connected thereto can have a limiting effect on it, preventing the locking member 4 from being separated from the plug-in portion 210 where it is located.

[0080] The accommodating portion 3 of each accommodating member extends along the third direction, and the fixed space formed by the two accommodating portions 3 also extends along the third direction. The fixed space has locking units on both sides opposite to each other along the second direction, and each side has multiple locking units. The multiple locking units on each side are sequentially spaced along the third direction, thereby making the connection between the first accommodating member 1 and the second accommodating member 2 more stable and more reliable. Fig.11 The accommodating portion 3 of the first accommodating member 1 is provided with a plurality of clamping members 110 on two opposite sides along the second direction, and the plurality of clamping members 110 on each side are sequentially arranged along the third direction. The accommodating portion 3 of the second accommodating member 2 is provided with a plurality of engaging structures on two opposite sides along the second direction, and the plurality of engaging structures on each side are sequentially arranged along the third direction.

[0081] refer to Fig.10 In this embodiment, every four locking members 4 are connected. In the locked state, each of the four locking members 4 is inserted into the corresponding plug-in portion 210, two of the four locking members 4 are distributed on one side of the accommodating portion 3 along the third direction and are adjacently arranged, and the other two are distributed on the other side of the accommodating portion 3 along the third direction and are adjacently arranged.

[0082] In some optional embodiments, the locking members 4 of all locking units are connected.

[0083] refer to Fig.10 In this embodiment, every four locking members 4 are connected via a connecting plate 12, one end of the locking member 4 is disposed on the connecting plate 12, and the other end of the locking member 4 is a tapered end for easy insertion into the plug-in portion 210. Each connecting plate 12 is rotatably connected to one of the accommodating members. Optionally, each connecting plate 12 is rotatably connected to the second accommodating member 2 via at least one connecting arm 121, and the material of the connecting arm 121 is an elastically deformable plastic material, so that the connecting plate 12 can rotate relative to the second accommodating member 2. In this embodiment, each connecting plate 12 is rotatably connected to the second accommodating member 2 via two connecting arms 121.

[0084] One of the first accommodating member 1 and the second accommodating member 2 has a protruding lifting portion 5. In response to the force applied to the lifting portion 5, the lifting portion 5 drives the first accommodating member 1 or the second accommodating member 2 to move, so that the first accommodating member 1 is separated from the second accommodating member 2. Figure 7 In this embodiment, both the first accommodating member 1 and the second accommodating member 2 are provided with a lifting portion 5. The lifting portion 5 of the first accommodating member 1 generally extends in a direction away from the second accommodating member 2, and the lifting portion 5 of the second accommodating member 2 generally extends in a direction away from the first accommodating member 1. By providing the lifting portion 5, it is convenient to apply force to the accommodating device to open the accommodating device.

[0085] The lift-off portion 5 of the first accommodating member 1 has substantially the same structure as the lift-off portion 5 of the second accommodating member 2. The lift-off portion 5 of the second accommodating member 2 is taken as an example to further illustrate the structure of the lift-off portion 5.

[0086] refer to Fig.14 The lifting portion 5 includes a connecting section 511 and a lifting section 521. The connecting section 511 generally extends along the first direction away from the first accommodating member 1, and the lifting section 521 generally extends along the third direction. One end of the connecting section 511 is connected to the first accommodating member 1, and the lifting section 521 is connected to the other end of the connecting section 511. Since the connecting section 511 extends along the first direction, the lifting section 521 protrudes relative to the second accommodating member 2.

[0087] by Figure 7 With the angle of as a reference, when separating the first accommodating component 1 and the second accommodating component 2, the locking mechanism is switched to the unlocked state, and then a downward force is applied to the lifting section 521 of the first accommodating component 1, and an upward force is applied to the lifting section 521 of the second accommodating component 2, thereby disengaging the first accommodating component 1 from the second accommodating component 2.

[0088] In the second embodiment of the present invention, the locking mechanism includes a locking unit and a pressure block 13, and the pressure block 13 is movably arranged on the second accommodating member 2. The locking unit includes a clamping member 110 and a coupling structure. The first accommodating member 1 and the second accommodating member 2 are connected via at least two locking units. In the locked state, at least two locking units are arranged in two rows, and the pressure block 13 is arranged between the two rows of locking units and abuts against the clamping members of each row of locking units, so that the clamping members remain in abutment with the abutting portion.

[0089] refer to Fig.17 The joint structure includes an inserting portion 210 and a resisting portion 212, and the inserting portion 210 has an opening portion 211. Fig.15 The clamping member 110 includes a first clamping portion 111 and a second clamping portion 112 connected to each other.

[0090] refer to Figure 15-16When the locking mechanism is in the locked state, the first accommodating member 1 and the second accommodating member 2 are stacked, the first clamping portion of the first accommodating member 1 penetrates into the plug-in portion 210 of the second accommodating member 2, and the first clamping portion 111 partially extends from the opening portion, so that the second clamping portion 112 extends from the opening portion 211, and the pressing block 13 is arranged in the second accommodating member and is located between the two rows of locking units. The pressing block 13 abuts against the first clamping portion 111 of each clamping member 110, so that the first clamping portion 111 abuts against the inner wall of the plug-in portion 210 where it is located, and the second clamping portion 112 of each clamping member 110 maintains abutment with the abutting portion 212, so that the clamping member 110 is engaged with the engaging structure.

[0091] Maintaining the abutment means that the second clamping portion 112 of the clamping member 110 and the abutting portion 212 can be stably abutted without being disengaged, thereby making the clamping member 110 engage with the engaging structure.

[0092] refer to Fig.19 The second clamping portion 112 protrudes relative to the outer wall of the first clamping portion 111. The first clamping portion 111 is elastic, and specifically, the material of the first clamping portion 111 is an elastically deformable plastic material. In response to the force applied to the clamping member 110, the first clamping portion 111 is elastically deformed so that the second clamping portion 112 abuts against the abutting portion 212.

[0093] In the locked state, the pressing block 13 abuts against the first clamping portion 111 of each clamping member 110 , so that the deformation of the first clamping portion 111 is restricted, and the second clamping portion 112 remains in abutment with the abutting portion 212 , so that the locking mechanism remains in the locked state.

[0094] When the pressure block 13 is taken out from between the two rows of locking units and the deformation restriction of the first clamping portion 111 of the clamping member 110 is released, the abutment between the second clamping member and the abutting portion 212 is no longer stable. When subjected to external force, the second clamping member and the abutting portion 212 will be disengaged. At this time, the clamping member 110 and the engaging structure are not in a clamped state, and the locking mechanism is in an unlocked state.

[0095] When the ureteral stent 6 is used, the pressing block 13 is taken out from between the two rows of locking units, and the first clamping portion 111 can be deformed to be able to move relative to the plug-in portion 210 in the plug-in portion 210, and the locking mechanism is switched to the unlocked state. When the first accommodating member 1 and the second accommodating member 2 are separated, the first clamping portion 111 moves in the plug-in portion 210 until the second clamping portion 112 no longer abuts against the abutting portion 212, and the first clamping portion 111 is separated from the plug-in portion 210.

[0096] In this embodiment, the plug-in portion 210 is a slot structure, and the plug-in portion 210 penetrates the second accommodating member 2 to form an opening portion 211 in the second accommodating member 2. Specifically, the plug-in portion 210 generally penetrates two opposite walls of the second accommodating member 2 along the first direction, and forms an opening portion 211 in one of the walls.

[0097] refer to Fig.17 In this embodiment, the abutting portion 212 is protruding relative to the edge of the opening portion 211, and the abutting portion 212 is located at the edge of the opening portion, so that the second clamping portion 112 abuts against the abutting portion 212. The second accommodating member 2 has two opposite wall surfaces along the first direction, one of which is provided with the accommodating portion 3, and the other is provided with the abutting portion 212. In the locked state, the pressing block 13 is also located on the wall surface of the second accommodating member 2 having the abutting portion 212.

[0098] refer to Fig.18 and Fig.19 The receiving portion 3 of each receiving member extends along the third direction, so that the fixed space formed by the two receiving portions 3 also extends along the third direction.

[0099] The first accommodating member 1 is connected to the second accommodating member 2 via a plurality of locking units. The plurality of locking units are arranged in two rows, and the two rows of locking units are arranged along the second direction on opposite sides of the fixed space along the second direction. The locking units in each row are arranged in sequence along the third direction, so that the connection between the first accommodating member 1 and the second accommodating member 2 is more stable and more reliable. The pressing block 13 extends along the third direction and is located between the two rows of locking units.

[0100] Specifically, refer to Fig.19 , a plurality of clamping members 110 are respectively arranged on two opposite sides of the accommodating portion 3 of the first accommodating member 1 along the second direction, and the plurality of clamping members 110 on each side are sequentially arranged at intervals along the third direction, thereby forming two rows of clamping members 110 on the first accommodating member 1. Fig.17The accommodating portion 3 of the second accommodating member 2 is provided with a plurality of engaging structures on two opposite sides along the second direction, and the plurality of engaging structures on each side are sequentially spaced along the third direction. The second accommodating member 2 is provided with two rows of abutting portions 212, each row includes a plurality of abutting portions 212, and the plug-in portion 210 is located between the two rows of abutting portions 212. In the locked state, the second engaging portions 112 of one row of the clamping members 110 cooperate with the abutting portions 212 of one row, and the second engaging portions 112 of the other row of the clamping members 110 cooperate with the abutting portions 212 of the other row. In the locked state, the pressure block 13 is located between the first clamping portions 111 of the two rows of clamping members 110 and abuts against the first clamping portion 111 of each clamping member 110, so that the first clamping portion 111 abuts against the inner wall of the plug-in portion 210 where it is located, and the second clamping portion 112 of each clamping member 110 remains in abutment with the abutting portion 212, thereby engaging the clamping member 110 with the engaging structure.

[0101] refer to Figure 15-16 When the locking mechanism is in a locked state, the first accommodating member 1 and the second accommodating member 2 are arranged opposite to each other along the first direction, the first clamping portion 111 of the clamping member 110 penetrates the plug-in portion 210 along the first direction, and the pressing block 13 abuts against the first clamping portion 111 of each clamping member 110 along a direction perpendicular to the first direction, and the first clamping portion 111 of each clamping member 110 abuts against the plug-in portion 210 where it is located along a direction perpendicular to the first direction, thereby limiting the relative movement of the first accommodating member 1 and the second accommodating member 2 along the direction perpendicular to the first direction, so that the first accommodating member 1 and the second accommodating member 2 have no relative movement in the direction perpendicular to the first direction. In other words, the first accommodating member 1 and the second accommodating member 2 have no relative movement on the plane perpendicular to the first direction.

[0102] When the locking mechanism is in the locked state, the second clamping portion 112 of the clamping member 110 abuts against the abutting portion 212 along the first direction, so that the first clamping portion 111 of the clamping member 110 is restricted in the plug-in portion 210 and cannot be separated from the plug-in portion 210 in which it is located, and the relative movement of the first accommodating member 1 and the second accommodating member 2 in the first direction is restricted, so that the first accommodating member 1 and the second accommodating member 2 also have no relative movement in the first direction, and the first accommodating member 1 and the second accommodating member 2 can maintain their relative positions.

[0103] In summary, when the locking mechanism is in a locked state, the first accommodating component 1 and the second accommodating component 2 have no relative movement in a plane perpendicular to the first direction, and the first accommodating component 1 and the second accommodating component 2 also have no relative movement in the first direction. The first accommodating component 1 and the second accommodating component 2 maintain their relative positions, thereby forming a fixed space between the accommodating portion 3 of the first accommodating component 1 and the accommodating portion 3 of the second accommodating component 2.

[0104] In this embodiment, both the first accommodating member 1 and the second accommodating member 2 are provided with a lift-off portion 5. The structure of the lift-off portion 5 in this embodiment is substantially the same as that of the lift-off portion 5 in the first embodiment, and will not be described in detail here.

[0105] refer to Fig. 20 The pressing block 13 has a plug-in connector 1301 at one end along the third direction, and a buckle 1302 at the other end opposite to the third direction. The buckle 1302 is rotatably connected to the pressing block 13, and the buckle 1302 has a buckle hole. Figure 17-18 The second accommodating member has a block 213 at one end along the third direction and a plug hole 522 at the other end. Specifically, the plug hole 522 is located at the connecting section 511 of the lifting portion.

[0106] When the locking mechanism is in the locked state, the pressing block 13 is located between the two rows of locking units, the plug-in connector 1301 of the pressing block 13 is inserted into the insertion hole 522 of the second accommodating member 2, and the buckle 1302 of the pressing block 13 is engaged with the clamping block 213 of the second accommodating member 2, so that the pressing block 13 is stably connected to the second accommodating member 2. The clamping block 213 has a convex portion 2131, and the clamping block 213 is inserted into the clamping hole 1312 of the buckle 1302 along the third direction. The convex portion 2131 extends from the clamping hole 1312 and abuts against the edge of the clamping hole 1312 along the third direction, so that the clamping block 213 will not be separated from the clamping hole 1312.

[0107] In this embodiment, the pressing block 13 has two buckles 1302, and the second receiving member 2 is correspondingly provided with two clamping blocks 213 to cooperate with the two buckles 1302. The clamping blocks 213 are elastic and can be elastically deformed.

[0108] When installing the pressing block 13 , first insert the connector 1301 of the pressing block 13 into the insertion hole 522 of the second accommodating member 2 , then rotate the buckle 1302 of the pressing block 13 and press the buckle to deform the block 213 of the second accommodating member 2 , so as to engage the buckle 1302 with the block 213 .

[0109] When using the ureteral stent, rotate the buckle 1302 of the pressing block 13 to separate it from the clamping block, and then pull the connector 1301 of the pressing block 13 out of the socket 522 of the second accommodating member 2. At this time, the clamping member 110 of the first accommodating member 1 and the engaging structure of the second accommodating member are both released, and the locking mechanism is switched to the unlocked state. By operating the lifting portion, the first accommodating member 1 can be separated from the second accommodating member 2 to open the accommodating device and take out the ureteral stent 6.

[0110] refer to Figure 16-19Furthermore, the locking mechanism of this embodiment further includes a limiting unit, which includes a locking groove 14 and a locking column 15. The first accommodating member is provided with the locking column 15, and the second accommodating member is provided with the locking groove 14. In the locked state, the locking column 15 is inserted into the locking groove 14 along the first direction, and the outer wall of the locking column 15 abuts against the inner wall of the locking groove 14, thereby further limiting the movement of the first accommodating member and the second accommodating member in a direction perpendicular to the first direction.

[0111] In the third embodiment of the present invention, the locking mechanism comprises a locking unit, and the locking unit comprises a clamping member 110 and a joint structure. The joint structure comprises an inserting portion 210 and a resisting portion 212 , and the inserting portion 210 has an opening 211 .

[0112] refer to Figure 21-24 The locking mechanism further includes a locking arm 218, which is rotatably disposed on the second accommodating member 2, and the engaging structure is disposed on the locking arm 218. In response to the locking arm 218 rotating toward the clamping member 110, the clamping member 110 penetrates the plug-in portion 210 and extends from the opening portion 211 to maintain abutment with the abutting portion 212, so that the clamping member 110 is engaged with the engaging structure. Maintaining abutment means that the clamping member 110 and the abutting portion 212 can be stably abutted and will not be disengaged, thereby enabling the clamping member 110 to engage with the engaging structure.

[0113] The first accommodating member 1 has two locking end faces opposite to each other along the second direction, and each locking end face is provided with a clamping member 110. The second accommodating member 2 is provided with two locking arms 218. In the locked state, one locking arm 218 is located at one of the locking end faces, and the other locking arm 218 is located at the other locking end face, and the engagement structure of each locking arm 218 is engaged with the clamping member 110 at the locking end face where it is located, thereby limiting the relative movement of the first accommodating member 1 and the second accommodating member 2 in the second direction and the direction opposite to the second direction.

[0114] refer to Fig.24 In this embodiment, the plug-in portion 210 is a slot structure. The plug-in portion 210 passes through two wall surfaces of the locking arm 218 and forms an opening portion 211 on one of the wall surfaces. A supporting portion 212 is formed at the edge of the opening portion 211 .

[0115] refer to Fig.25 The clamping member 110 has a first clamping portion 111 and a second clamping portion 112 connected to each other. The locking arm 218 can rotate relative to the second receiving member 2 until the first clamping portion 111 penetrates into the plug-in portion 210. Figure 19-20In the locked state, the first clamping portion 111 penetrates the plug-in portion 210, and the second clamping portion 112 extends from the opening 211 and maintains contact with the abutting portion 212, so that the clamping member 110 is engaged with the engagement structure. The above-mentioned clamping member 110 and the abutting portion 212 maintain contact specifically means that the second clamping portion 112 of the clamping member 110 maintains contact with the abutting portion 212.

[0116] The second clamping portion 112 protrudes relative to the outer wall of the clamping member 110. The first clamping portion 111 is elastic, specifically, the first clamping portion 111 is made of elastically deformable plastic material, and in response to the force applied to the clamping member 110, the first clamping portion 111 is elastically deformed to make the second clamping portion 112 abut against the abutting portion 212.

[0117] refer to Figure 21-22 In the locked state, the first accommodating member 1 and the second accommodating member 2 are arranged opposite to each other along the first direction, the first clamping portion 111 of the clamping member 110 generally penetrates the plug-in portion 210 along the second direction, and the first clamping portion 111 abuts against the inner wall of the plug-in portion 210 along the first direction to limit the relative movement of the first accommodating member 1 and the second accommodating member 2 in the first direction. At the same time, the first clamping portion 111 also abuts against the inner wall of the plug-in portion 210 along the third direction and the direction opposite to the third direction, limiting the relative movement of the first accommodating member 1 and the second accommodating member 2 in the third direction and the direction opposite to the third direction. The second clamping portion 112 of the clamping member 110 extends from the plug-in portion 210 through the opening portion 211 and abuts against the abutting portion 212 along the second direction, thereby limiting the relative movement of the first accommodating member 1 and the second accommodating member 2 in the second direction, and making the first clamping portion 111 of the clamping member 110 restricted in the plug-in portion 210 and unable to detach from the plug-in portion 210 in which it is located, so that the clamping member 110 and the engaging structure can be stably engaged.

[0118] In summary, when the locking mechanism is in a locked state, the first accommodating component 1 and the second accommodating component 2 have no relative movement in the first direction, the second direction, the third direction and the direction opposite to the three directions, so that the first accommodating component 1 and the second accommodating component 2 maintain a relative position to form a fixed space between the accommodating portion 3 of the first accommodating component 1 and the accommodating portion 3 of the second accommodating component 2.

[0119] The accommodating portion 3 of the first accommodating member 1 and the accommodating portion 3 of the second accommodating member 2 both extend along the third direction, so that the fixed space formed by the two accommodating portions 3 also extends along the third direction. The fixed space has locking units on both sides opposite to each other along the second direction, and each side has multiple locking units, and the multiple locking units on each side are sequentially spaced along the third direction, thereby making the connection between the first accommodating member 1 and the second accommodating member 2 more stable and more reliable.

[0120] Specifically, refer to Fig. 22As described above, the first accommodating member has two locking end faces opposite to each other along the second direction, and each locking end face is provided with a clip. For the convenience of clear description, the two locking end faces are defined as the first locking end face and the second locking end face. The first locking end face of the first accommodating member 1 is provided with a plurality of clips 110, and the plurality of clips 110 are arranged in sequence along the third direction on the first locking end face. The second locking end face of the first accommodating member 1 is also provided with a plurality of clips 110, and the plurality of clips 110 are arranged in sequence along the third direction on the second locking end face. Each clip 110 extends substantially along the second direction.

[0121] The second accommodating member is provided with two locking arms 218. Each locking arm 218 is provided with a plurality of engaging structures. The plurality of engaging structures of one locking arm 218 engages with the plurality of clamping members 110 of the first locking end face, and the plurality of engaging structures of the other locking arm 218 engages with the plurality of clamping members 110 of the second locking end face.

[0122] When connecting the first accommodating member 1 and the second accommodating member 2, the first accommodating member 1 is stacked with the second accommodating member 2, and then each locking arm 218 of the second accommodating member 2 is rotated so that the first clamping portion 111 of each clamping member 110 is inserted into the corresponding plug-in portion 210 of the locking arm 218, and then the locking arm 218 is pressed so that the second clamping portion 112 of the clamping member 110 is abutted against the abutting portion 212, thereby making each clamping member 110 engage with the corresponding engaging structure.

[0123] When the ureteral stent 6 is used, each locking arm 218 is rotated separately so that the multiple engagement structures of each locking arm 218 are disengaged from the corresponding snap-in parts, and the locking mechanism is switched to the unlocked state, so that the first accommodating part 1 can be separated from the second accommodating part 2 to open the accommodating device and remove the ureteral stent 6.

[0124] refer to Fig.24 Each locking arm 218 includes a pivoting portion 2181 and a clamping portion 2182 connected to each other, and the engaging structure is disposed on the clamping portion 2182 of the locking arm 218. The pivoting portion 2181 is connected to the second accommodating member 2, and the material of the pivoting portion 2181 is an elastically deformable plastic material, so that the clamping portion 2182 can rotate relative to the second accommodating member 2 until the first clamping portion 111 penetrates the plug-in portion 210. Each locking arm 218 includes a plurality of pivoting portions 2181, and the plurality of pivoting portions 2181 are sequentially spaced along the third direction, so that the connection between the clamping portion 2182 and the second accommodating member 2 is more stable.

[0125] Each locking arm 218 further includes an operating portion 2183. The operating portion 2183 extends from the engaging portion 2183, so that the engaging mechanism of the locking arm 218 can be separated from the engaging member by applying force to the operating portion, which is convenient for the user to operate.

[0126] In this embodiment, both the first accommodating member 1 and the second accommodating member 2 are provided with a lift-off portion 5. The structure of the lift-off portion 5 in this embodiment is substantially the same as that of the lift-off portion 5 in the first embodiment, and will not be described in detail here.

[0127] refer to Figure 22-23 , Fig.25 Furthermore, the locking mechanism of this embodiment further includes a limiting unit, which includes a locking groove 14 and a locking column 15. The first accommodating member is provided with the locking column 15, and the second accommodating member is provided with the locking groove 14. In the locked state, the locking column 15 is inserted into the locking groove 14 along the first direction, and the outer wall of the locking column 15 abuts against the inner wall of the locking groove 14, thereby further limiting the movement of the first accommodating member and the second accommodating member in a direction perpendicular to the first direction.

[0128] In the fourth embodiment of the present invention, the clamping member 110 includes a first clamping member 114 and a second clamping member 115, and the first clamping member 114 and the second clamping member 115 are arranged opposite to each other along the third direction. The engaging structure includes a first engaging structure 214 and a second engaging structure 215, and the first engaging structure 214 and the second engaging structure 215 are arranged opposite to each other along the third direction.

[0129] As described above, the locking mechanism has a locked state and an unlocked state. In this embodiment, the locking mechanism also has an intermediate state. In the locked state, the first shape fit formed by the first clamping member 114 and the first engagement structure 214 is maintained, and the second shape fit formed by the second clamping member and the second engagement structure is maintained, so that the first accommodating member 1 and the second accommodating member 2 maintain a relative position. In the unlocked state, the first shape fit is released, and the second shape fit is released at the same time, so that the first accommodating member 1 and the second accommodating member 2 can be separated.

[0130] In the locked state, in response to the first external force, the first clamping member 114 is separated from the first engagement structure 214 so that the first shape fit is released, and the second shape fit is maintained, so that the locking mechanism switches to the intermediate state, at which time the first accommodating member can rotate relative to the second accommodating member so that the second shape fit can be released. In the intermediate state, in response to the second external force, the first accommodating member rotates relative to the second accommodating member, and the second clamping member 115 is separated from the second engagement structure 215 so that the second shape fit is released, so that the locking mechanism switches to the unlocked state.

[0131] The "first shape fit" specifically means that the first clamping member 114 matches the shape of the first engaging structure. When the first clamping member 114 and the first engaging structure 214 are in abutment with each other due to their matching shapes, the relative positions of the first clamping member 114 and the first engaging structure 214 are fixed. The meaning of the "second shape fit" can refer to the "first shape fit".

[0132] refer to Fig.26 , the first accommodating member 1 has a first end and a second end opposite to each other along the third direction. The first clamping member 114 is disposed at the first end of the first accommodating member 1. The first clamping member 114 extends along the first direction. In the locked state, the first accommodating member 1 and the second accommodating member 2 are disposed opposite to each other along the first direction. The first clamping member 114 abuts against the first engagement structure 214 to restrict the second accommodating member 2 from moving relative to the first accommodating member 1 in a direction opposite to the third direction, that is, the first shape fit is maintained.

[0133] refer to Fig.26 , the second clamping member 115 is arranged at the second end of the first accommodating member 1, and the second clamping member 115 is arc-shaped. The second engaging structure 215 is arranged at the second end of the second accommodating member 2, and the second engaging structure 215 is also arc-shaped and matches the shape of the second clamping member 115. In the locked state, the second clamping member 115 is buckled with the second engaging structure 215, and the second clamping member 115 abuts against the second engaging structure 215 to limit the second accommodating member 2 from moving relative to the first accommodating member 1 along the third direction, that is, the second shape fit is maintained.

[0134] refer to Figure 27-28 The second clamping member 115 gradually bends upward from the second accommodating member 2 . Specifically, the second clamping member 115 first extends in a direction away from the first accommodating member 1 , and then extends in a direction close to the first accommodating member 1 .

[0135] The second accommodating member 2 also has a first end and a second end opposite to each other along the third direction. The first engaging structure 214 is located at the first end of the second accommodating member, and the second engaging structure 215 is disposed at the second end of the second accommodating member 2. Fig. 27 For reference, the left end surface of the second accommodating member 2 constitutes the first engaging structure 214 , and when the locking mechanism is in the locked state, the first clamping member 114 abuts against the left end surface of the second accommodating member 2 .

[0136] Optionally, in this embodiment, the first end of the first accommodating member 1 is provided with two first clamping members 114, and the first end of the second accommodating member 2 forms two first engaging structures 214. The second end of the first accommodating member 1 is provided with two second clamping members 115, and the second end of the second accommodating member 2 is provided with two second engaging structures 215.

[0137] The second clamping member 115 is elastic, specifically, the material of the second clamping member 115 is an elastically deformable plastic material, and in response to the force applied to the second clamping member 115, the second clamping member 115 is elastically deformed to be engaged with the second engagement structure 215, thereby abutting against the second engagement structure 215. At the same time, the second clamping member 115 is elastically deformed, so that when the second engagement structure 215 of the second accommodating member 2 abuts against the second clamping member 115, the second accommodating member 2 can be displaced along the third direction relative to the first accommodating member 1, so that the second accommodating member can be clamped between the first clamping member 114 and the second clamping member 115.

[0138] Optionally, the first clamping member 114 is elastic. Specifically, the first clamping member 114 is made of elastically deformable plastic material. In response to force being applied to the first clamping member 114 , the first clamping member 114 is elastically deformed to be engaged with the first engaging structure 214 .

[0139] refer to Fig.29 The clamping member further comprises a third clamping member 116 and a fourth clamping member 117. The third clamping member 116 and the fourth clamping member 117 are arranged opposite to each other along the second direction. Both the third clamping member 116 and the fourth clamping member 117 are elastic.

[0140] The bonding structure further includes a third bonding structure 216 and a fourth bonding structure 217 , and the third bonding structure 216 and the fourth bonding structure 217 are arranged opposite to each other along the second direction.

[0141] In the locked state, the second accommodating member 2 is located between the third clamping member 116 and the fourth clamping member 117, and the third clamping member 116 abuts against the third engaging structure 216 to limit the second accommodating member 2 from moving relative to the first accommodating member 1 in a direction opposite to the second direction, and the fourth clamping member 117 abuts against the fourth engaging structure 217 to limit the second accommodating member 2 from moving relative to the first accommodating member 1 in the second direction.

[0142] refer to Fig.29 , the third clamping member 116 and the fourth clamping member 117 both extend along the third direction. Fig. 27 The second accommodating member 2 has a third end and a fourth end opposite to each other along the second direction, the end surface of the third end of the second accommodating member 2 constitutes a third engagement structure 216, and the end surface of the fourth end of the second accommodating member 2 constitutes a fourth engagement structure 217. In the locked state, the second accommodating member 2 is located between the third clamping member 116 and the fourth clamping member 117, the third clamping member 116 abuts against the end surface of the third end of the second accommodating member 2, and the fourth clamping member 117 abuts against the end surface of the fourth end of the second accommodating member 2.

[0143] The clamping member further includes a fifth clamping member 118, and the engaging structure further includes a fifth engaging structure. The fifth clamping member 118 is disposed on one or more of the first clamping member 114, the third clamping member 116, and the fourth clamping member 117. In the locked state, the fifth clamping member 118 abuts against the fifth engaging structure to restrict the second accommodating member 2 from moving relative to the first accommodating member 1 in a direction opposite to the first direction.

[0144] Specifically, refer to Fig.26 and Fig.29 , the first clamping member 114, the third clamping member 116 and the fourth clamping member 117 are all provided with a fifth clamping member 118. The fifth clamping member 118 provided on the first clamping member 114 extends along the third direction, and the fifth clamping members 118 provided on the third clamping member 116 and the fourth clamping member 117 both extend along the second direction. The upper end surface of the second accommodating member 2 forms a plurality of fifth engagement structures. Thus, in the locked state, each fifth clamping member 118 abuts against the upper end surface of the second accommodating member 2 to restrict the second accommodating member 2 from moving relative to the first accommodating member 1 in a direction opposite to the first direction.

[0145] In summary, the first accommodating component 1 and the second accommodating component 2 have no relative movement in the first direction and also have no relative movement in a plane perpendicular to the first direction, so that the first accommodating component 1 and the second accommodating component 2 maintain relative positions to form a fixed space.

[0146] When connecting the first accommodating member 1 and the second accommodating member 2, first accommodate the second coupling structure of the second accommodating member 2 in the second clamping member 115 of the first accommodating member 1, and then press the second accommodating member 2 so that the first clamping member 114, the third clamping member 116 and the fourth clamping member 117 of the first accommodating member are all deformed, so that the second accommodating member 2 is accommodated between the third clamping member 116 and the fourth clamping member 117, and the first clamping member 114 is engaged with the first coupling structure 214, the second clamping member 115 is engaged with the second coupling structure 215, the third clamping member 116 is engaged with the third coupling structure 216, the fourth clamping member 117 is engaged with the fourth coupling structure 217, and the fifth clamping member 118 is engaged with the fifth coupling structure, so that the locking unit is switched to the locked state, and a fixed space is formed between the accommodating portion 3 of the first accommodating member 1 and the accommodating portion 3 of the second accommodating member 2.

[0147] When the ureteral stent 6 is used, the first clamping member 114 is disengaged from the first engaging structure 214, so that the locking unit switches from the locked state to the intermediate state, and then the first accommodating member 1 is rotated with the second clamping member 115 as the pivot point, so that the second clamping member 115 is separated from the second engaging structure 215, and the locking mechanism switches to the unlocked state, and the first accommodating member 1 is separated from the second accommodating member 2. In the process of the first clamping member 114 being disengaged from the first engaging structure 214, the third clamping member 116 is also separated from the third engaging structure 216, the fourth clamping member 117 is also separated from the fourth engaging structure 217, and the fifth clamping member 118 is also separated from the fifth engaging structure.

[0148] refer to Figure 26-27 In this embodiment, the second accommodating member 1 is provided with a lifting portion 5. The lifting portion 5 is provided at the first end of the first accommodating member 1 and extends in a direction opposite to the third direction. In response to the force applied to the lifting portion 5, the lifting portion 5 drives the second accommodating member 2 to move relative to the first accommodating member 1, so that the first accommodating member 1 is disengaged from the second accommodating member 2. Specifically, when the first accommodating member 1 and the second accommodating member 2 are disassembled, an upward force is applied to the lifting portion 5, so that the first clamping member 114 is disengaged from the first engaging structure 214. Optionally, in this embodiment, two lifting portions 5 are provided, and the two lifting portions 5 are both provided at the first end of the second accommodating member 1 and have substantially the same structure.

[0149] In summary, the first accommodating component 1 and the second accommodating component 2 of the accommodating device of the present invention are connected via a locking mechanism. When the locking mechanism is in a locked state, the first accommodating component 1 and the second accommodating component 2 maintain a relative position, so that a fixed space is formed between the accommodating portions 3 of the first accommodating component 1 and the second accommodating component 2 to accommodate the ureteral stent, which can prevent the ureteral stent 6 from expanding and deforming before use, and the locking mechanism has an unlocked state, which is convenient for disassembling the first accommodating component 2 and the second accommodating component 2 to remove the ureteral stent 6.
