[0052] Figure 1 A schematic diagram schematically shows the structure of the first connecting member of an embodiment of the utility model, Figure 2 A schematic diagram schematically shows the structure of the second connecting member in one embodiment of the present invention. Figure 3 A cross-sectional view schematically showing a multi-lumen tube according to an embodiment of the present invention is shown in FIG. Figure 1-3 As shown, a quick-connect device of the utility model includes:

[0053] The first connecting member 10 has a first passage 101 extending axially therethrough, and the first passage 101 is used for the pipeline in the nailing control assembly 60 to pass through;

[0054] The second connecting member 20 has a second channel 201 and a third channel 202 axially disposed therein. One end of the third channel 202 is connected to the second channel 201, and the other end is connected to the multi-lumen tube 30. The first connecting member 10 can be inserted into the second channel 201 to connect the first channel 101 with the third channel 202.

[0055] The multi-lumen tube 30 includes a first chamber 301 and a second chamber 302. The first chamber 301 is in communication with the thread lock control assembly 50 and is used for the pipeline in the thread lock control assembly 50 to pass through. The second chamber 302 is in communication with the third channel 202 and is used for the pipeline in the nailing control assembly 60 to pass through.

[0056] The diameter of the third channel 202 is smaller than that of the second channel 201. A first groove 2021 is provided on the end face of the third channel 202 facing the second channel 201, and a first protrusion 102 is provided on the surface of the first connecting member 10 facing the second connecting member 20. When the first connecting member 10 is inserted into the second channel 201 and the first protrusion 102 is inserted into the first groove 2021, the first channel 101 is arranged corresponding to the second chamber 302.

[0057] Specifically, the nailing control assembly 60 is installed with the thread lock control assembly 50 to implement the surgical operation of the valve ring repair. When the pipelines in the nailing control assembly 60 are extended, the multiple pipelines will be scattered. Since the thread lock control assembly 50 is connected to the multi-lumen tube 30, the multi-lumen tube 30 has multiple chambers. When in use, the pipelines in the nailing control assembly 60 need to be inserted into the corresponding chambers of the multi-lumen tube 30 to complete the surgical operation. The scattered pipelines need to be manually controlled by the doctor to gather and adjust them to correspond to the chambers in the multi-lumen tube 30. The overall operation is cumbersome and inefficient.

[0058] By putting the first connecting piece 10 onto the pipeline, the scattered pipelines can be gathered. At the same time, by inserting the first connecting piece 10 into the second connecting piece 20 and the first protrusion 102 into the first groove 2021, it can be ensured that the pipeline in the nail control component 60 is correctly inserted into the corresponding chamber of the multi-lumen tube 30. The nail control component 60 and the wire lock control component 50 can be quickly installed, saving installation time and improving work efficiency.

[0059] Furthermore, Figure 4 A schematic diagram schematically shows the structure of the first shell of an embodiment of the present invention, Figure 5 A schematic diagram schematically shows the structure of the second shell of an embodiment of the utility model, Figure 6 The schematic diagram of the structure of the limit sleeve of one embodiment of the present invention is shown as follows: Figure 4-6 As shown:

[0060] The first connecting member 10 includes a first shell 103, a second shell 104 and a limiting member 105;

[0061] The first shell 103 and the second shell 104 are detachably connected. When the first shell 103 and the second shell 104 are combined, the first channel 101 is formed inside the first shell 103 and the second shell 104. The stopper 105 is used to combine the first shell 103 and the second shell 104.

[0062] A second protrusion 1031 is provided on the first joint surface of the first shell 103, and a second groove 1041 is provided on the second joint surface of the second shell 104. When the first shell 103 and the second shell 104 are assembled, the first joint surface and the second joint surface are abutted, and the second protrusion 1031 is inserted into the second groove 1041 to lock the axial movement of the first shell 103 and the second shell 104.

[0063] The limiting member 105 includes a limiting sleeve 1051 , through which the pipeline in the nailing control assembly 60 passes. When the first shell 103 and the second shell 104 can be inserted into the limiting sleeve 1051 at the same time, the limiting sleeve 1051 limits the radial movement of the first shell 103 and the second shell 104 .

[0064] Specifically, the first shell 103 and the second shell 104 are detachably connected. When in use, the first shell 103 and the second shell 104 can be placed around the pipeline, and the first shell 103 and the second shell 104 can be combined by approaching each other, while surrounding the pipeline to achieve the gathering of the pipeline. After use, the first shell 103 and the second shell 104 can be moved away from each other for disassembly, and the first connecting piece 10 can be disassembled without affecting the insertion of the pipeline into the multi-lumen tube 30, which is convenient for use.

[0065] At the same time, when the first shell 103 and the second shell 104 are combined, the cooperation between the second protrusion 1031 and the second groove 1041 can mutually limit the axial movement of the first shell 103 and the second shell 104. At the same time, when the limit sleeve 1051 is sleeved on the first shell 103 and the second shell 104, it can limit the radial movement of the first shell 103 and the second shell 104, and fix the combination state of the two.

[0066] Furthermore, the limiting member 105 further includes a limiting post 1052;

[0067] First through holes 1032 are provided on both axial sides of the second protrusion 1031, and second through holes 1042 are provided on both axial sides of the second housing 104. The second through holes 1042 pass through the second groove 1041. When the second protrusion 1031 is inserted into the second groove 1041, the first through holes 1032 are connected to the second through holes 1042.

[0068] A third through hole 10511 is axially arranged in the limiting sleeve 1051. When the first shell 103 and the second shell 104 are inserted into the limiting sleeve 1051, the limiting column 1052 can pass through the third through hole 10511, the second through hole 1042 and the first through hole 1032 in sequence to limit the axial rotation of the first shell 103 and the second shell 104 relative to the limiting sleeve 1051.

[0069] Specifically, when the first shell 103 and the second shell 104 are combined, the limiting sleeve 1051 can be used to connect the two to limit the radial movement of the first shell 103 and the second shell 104, but the connection between the two and the limiting sleeve 1051 is unstable, and the combination as a whole can rotate within the limiting sleeve 1051. When the doctor controls the installation of the limiting sleeve 1051 and the thread lock control assembly 50, the first shell 103 and the second shell 104 enter the thread lock control assembly 50, which is not conducive to the doctor controlling its first channel 101 to align with the second chamber 302. However, through the setting of the limiting column 1052, the limiting sleeve 1051 can be fixedly connected to the combined shape of the first shell 103 and the second shell 104. The internal first channel 101 can be aligned with the second chamber 302 by positioning the limiting sleeve 1051, thereby completing the installation of the nailing control assembly 60 and the thread lock control assembly 50.

[0070] A corresponding slider 10512 can be set on the side wall of the limit sleeve 1051, and a corresponding slide groove can be set on the inner wall of the shell of the wire lock control component 50. By inserting the slider 10512 into the slide groove, the limit sleeve 1051 can be quickly positioned, and the first channel 101 and the second chamber 302 can be quickly positioned at the same time, thereby achieving quick installation.

[0071] Furthermore, the limiting member 105 further includes a limiting pin 1053;

[0072] A fourth through hole 10513 is provided on the circumferential side wall of the limiting sleeve 1051, and a first limiting hole 106 is provided on the circumferential side wall of the first shell 103 or the second shell 104. However, when the limiting pin 1053 passes through the fourth through hole 10513 and is inserted into the first limiting hole 106, the limiting pin 1053 limits the axial movement and circumferential rotation of the first shell 103 and the second shell 104 relative to the limiting sleeve 1051.

[0073] Specifically, when the first shell 103 and the second shell 104 are combined and located in the limiting sleeve 1051, the axial movement of the first shell 103 and the second shell 104 relative to the limiting sleeve 1051 is not limited. In order to prevent the limiting sleeve 1051 from slipping out and no longer wrapping the first shell 103 and the second shell 104, the first shell 103 and the second shell 104 can be confined in the limiting sleeve 1051 by setting the limiting pin 1053. When the limiting sleeve 1051 is moved or rotated, the internal first shell 103 and the second shell 104 can move synchronously.

[0074] Further, if Figure 6 As shown, a third groove 10514 is provided on the axial side wall of the limiting sleeve 1051. The third groove 10514 extends radially and connects the interior and exterior spaces of the limiting sleeve 1051.

[0075] The third groove 10514 is used for the pipeline in the nailing control assembly 60 to enter or leave the limiting sleeve 1051 in the radial direction.

[0076] In addition, a fourth channel 10515 and a fifth channel 10516 are axially arranged in the limit sleeve 1051, and the fourth channel 10515 is connected to the fifth channel 10516. The fourth channel 10515 is used for inserting the first shell 103 and the second shell 104, and the fifth channel 10516 is used for the pipeline in the nail control component 60 to pass through. The diameter of the fourth channel 10515 is larger than the diameter of the fifth channel 10516, so that the fifth channel 10516 limits the axial movement of the first shell 103 and the second shell 104.

[0077] With such an arrangement, during installation, the pipeline is first gathered by combining the first shell 103 and the second shell 104, and then the limiting sleeve 1051 is moved from the radial direction of the pipeline to coaxial with the pipeline through the third groove 10514. At this time, the limiting sleeve 1051 is controlled to move axially in the direction close to the first shell 103 and the second shell 104, so that the first shell 103 and the second shell 104 are inserted into the limiting sleeve 1051 and radially limited. At this time, the combination of the first shell 103 and the second shell 104 and the limiting sleeve 1051 are circumferentially limited by inserting the limiting column 1052 through the third through hole 10511. The first shell 103 and the second shell 104 are axially limited by inserting the locking pin 1053, so that the first shell 103, the second shell 104 and the limiting sleeve 1051 are completely fixedly connected, so that the pipeline no longer changes position, and the assembly of the first connecting member 10 is completed.

[0078] Furthermore, Figure 7 A schematic diagram showing the structure of a seal according to an embodiment of the present invention is shown as follows: Figure 7 As shown, a sealing member 203 is provided in the second connecting member 20;

[0079] The sealing member 203 is located in the second channel 201 and is disposed in the third channel 202. The sealing member 203 is used to seal the inner space of the second connecting member 20.

[0080] When the first connecting member 10 is inserted into the second connecting member 20 , the first shell 103 and the second shell 104 pass through the sealing member 203 , and the limiting sleeve 1051 is located outside the second channel 201 .

[0081] Specifically, the sealing member 203 is made of elastic material, and a cross-shaped sealing opening 2031 is provided at the center of the sealing member 203 for the first shell 103 and the second shell 104 to pass through;

[0082] When the first connecting member 10 is inserted into the second connecting member 20 , the first shell 103 and the second shell 104 are squeezed and pass through the sealing opening 2031 .

[0083] In this way, the sealing opening 2031 on the sealing member 203 can ensure that the interior of the second connecting member 20 is sealed when the first connecting member 10 is not inserted, and at the same time, the first connecting member 10 can be inserted without disassembling parts.

[0084] Furthermore, a liquid injection channel 204 is provided on the side wall of the second connecting member 20 . The liquid injection channel 204 is located between the sealing member 203 and the third channel 202 . The liquid injection channel 204 is communicated with the second channel 201 . The liquid injection channel 204 is used to inject sealing liquid.

[0085] With such arrangement, the sealing liquid is injected into the interior through the injection channel 204, so that the internal air can be exhausted and bubbles in the tube gap can be prevented from entering the human body.

[0086] Furthermore, Figure 8 The schematic diagram of the structure of the conveying system of one embodiment of the present invention is shown as follows: Figure 8 As shown, the present invention also provides a delivery system, comprising a quick-connect device as described above, and further comprising a sheath bending assembly 40, a wire lock control assembly 50 and a nailing control assembly 60;

[0087] The second connecting member 20 is disposed in the wire lock control assembly 50 , and the pipeline extending from the nailing control assembly 60 passes through the first connecting member 10 ;

[0088] One end of the wire lock control assembly 50 is connected to the sheath bending assembly 40, and the other end is connected to the nailing control assembly 60 through a quick-connect device. The pipeline in the wire lock control assembly 50 enters the first chamber 301 of the multi-lumen tube 30 through the second connecting piece 20;

[0089] When the first connecting member 10 is connected to the second connecting member 20 , the pipeline in the nailing control assembly 60 can enter the second chamber 302 in the multi-lumen tube 30 .

[0090] Specifically, one end of the sheath bending adjustment component 40 is connected to the sheath, and the other end is connected to the wire locking control component 50. The other end of the wire locking control component 50 is connected to the nailing control component 60. The sheath bending adjustment component 40 can bend the sheath, the wire locking control component 50 can control the wire locking component to lock the anchor, and the nailing control component 60 can control the anchor to be nailed into the valve ring tissue.

[0091] When the nailing control assembly 60 is connected to the wire lock control assembly 50 , the quick connection device can realize a quick connection between the two, solving the problem that the nailing control assembly 60 extends out of the pipeline and is scattered, and cannot be quickly extended into the corresponding cavity of the multi-lumen tube 30 .

[0092] To sum up, through the solution of the present invention, a first channel 101 is provided in the first connecting member 10, and the first channel 101 can be used for the pipeline in the nailing control component 60 to pass through, and it can gather the pipeline extending out of the nailing control component 60. At the same time, one end of the second connecting member 20 is connected to the multi-lumen tube 30, and the other end is connected to the first connecting member 10.
