Description

Technical Field

[0001] The present invention relates to the technical field of valve repair, and in particular to a nailing control component and a delivery system. Background Art

[0002] Heart valves are checkpoints between different cardiovascular structures. They can only open and close in a certain direction to ensure that blood can only flow forward and not backward. The mitral valve is a "one-way valve" between the left atrium and the left ventricle, ensuring that blood circulation flows from the left atrium to the left ventricle in a directional manner and passes a certain amount of blood flow. Blood flows from the left atrium through the mitral valve into the left ventricle, and is then pumped into the aorta by the left ventricle and flows to the whole body. The mitral valve opens, and blood flows from the left atrium into the left ventricle; then the mitral valve closes to ensure that when the left ventricle contracts to pump blood to the aorta, blood does not flow back into the left atrium. If the mitral valve is diseased and cannot be fully closed, it will cause blood to flow back into the left atrium when the left ventricle contracts. This is mitral regurgitation.

[0003] Mitral regurgitation is the most common heart valve disease worldwide. Regurgitation reduces blood flow to various parts of the body. In order to compensate, the heart will try to pump blood more forcefully, which increases the heart's workload. Patients with severe mitral regurgitation may experience a variety of debilitating symptoms, such as shortness of breath, palpitations, dizziness and fatigue. These patients face the risk of poor quality of life, significant limitation of activities, repeated hospitalizations due to heart failure and increased mortality. Chronic severe mitral regurgitation is often accompanied by heart failure, which can lead to death if not treated.

[0004] Currently, in valve repair surgery, the control mode of the device that controls the anchor to be nailed into the valve ring tissue is relatively simple and can only achieve simple movement and rotation. Therefore, the doctor mostly relies on his experience to determine the screwing force during nailing.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0020] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present invention are described at the angles shown in the drawings and should not be understood as limiting the embodiments of the present invention. In addition, in the context, it should also be understood that when it is mentioned that an element is formed "on" or "under" another element, it can not only be formed directly "on" or "under" another element, but also be formed "on" or "under" another element indirectly through an intermediate element.

[0021] Figure 1 A schematic diagram schematically shows the structure of a nailing control component according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, a nailing control assembly of the present invention comprises: Housing 10, bending pipe control device 20, spring pipe control device 30 and anchor control device 40; The housing 10 includes a first housing 101 and a second housing 102 , wherein the second housing 102 is axially movable relative to the first housing 101 ; The bending pipe control device 20 is provided with an axially penetrating nailing bending pipe 201, and the nailing bending pipe 201 can move axially and rotate circumferentially relative to the bending pipe control device 20. The bending pipe control device 20 is used to control the bending angle of the nailing bending pipe; The spring tube control device 30 is provided with an axially penetrating nail spring tube 301, which is arranged in the nail bending adjustment tube 201. The nail spring tube 301 can move axially and rotate circumferentially relative to the spring tube control device 30. An axially penetrating anchor cable 401 is provided in the anchor control device 40. The anchor cable 401 is disposed in the nail spring tube 301. The anchor cable 401 can move axially and rotate circumferentially relative to the anchor control device 40 so that the anchor at the end of the anchor cable 401 can be nailed into the valve ring tissue.

[0022] In this way, the bending tube control device 20 can control the axial movement, circumferential rotation and bending of the nailing bending tube 201 therein, the spring tube control device 30 can control the axial movement and circumferential rotation of the nailing spring tube 301 therein, and the anchor control device 40 can control the axial movement and circumferential rotation of the anchor steel cable 401 therein. Through multiple driving modes, each component controls the pipeline separately, making it more convenient for doctors to use and the control more precise, thereby improving the safety of surgery.

[0023] Further, Figure 2 A schematic diagram schematically shows the coordination of the first driving structure and the second driving structure in one embodiment of the present invention, as shown in FIG. Figure 2 As shown: The pipe bending control device 20 includes a first driving structure 202 and a second driving structure 203; The first driving structure 202 is axially inserted into the housing 10, and the second driving structure 203 penetrates the side wall of the housing 10; The first driving structure 202 can move axially and rotate circumferentially relative to the housing 10 , and the second driving structure 203 is meshed with the first driving structure 202 through gears, so that the first driving structure 202 can move axially in steps.

[0024] Specifically, the second driving structure 203 includes a rotating shaft 2031, a second rotating column 2032 and a gear 2033. The rotating shaft 2031 penetrates the housing 10 from the circumferential direction, and the end of the rotating shaft 2031 is exposed from the housing 10, and the rotating shaft 2031 is supported by the housing 10. The second rotating column 2032 is sleeved on the rotating shaft 2031, and the second rotating column 2032 is rotatably connected to the rotating shaft 2031. Both ends of the second rotating column 2032 are also exposed from the housing 10. The gear 2033 is sleeved on the second rotating column 2032, and the gear 2033 is fixedly connected to the second rotating column 2032. The second driving structure 203 also includes a first handle 2034, which is disposed on the side wall of the housing 10 and is rotatably connected to the side wall of the housing 10. The rotating shaft 2031 and the second rotating column 2032 are inserted into the first handle 2034. The rotating shaft 2031 is movably connected to the first handle 2034, and the second rotating column 2032 is fixedly connected to the first handle 2034. When the first handle 2034 is driven to rotate, the second rotating column 2032 is driven to rotate synchronously, thereby driving the gear 2033 to rotate synchronously. A circumferential rack 2021 is provided on the circumferential side wall of the first driving structure 202, and the circumferential rack 2021 is meshedly connected with the gear 2033. When the gear 2033 rotates, it drives the first driving structure 202 to move axially stepwise through the connection with the circumferential rack 2021, thereby realizing the axial stepwise movement of the nailing and bending tube 201.

[0025] In this way, through the mating connection between the first drive structure 202 and the second drive structure 203, when the two are meshed, when the second drive structure 203 is controlled to rotate, the axial movement of the first drive structure 202 can be controlled through the meshing connection. At the same time, when the first drive structure 202 moves axially or rotates circumferentially, the second drive structure 203 will not change position in the axial or radial direction, which solves the problem that when one of the two is moved in a threaded mating connection, the other must change position.

[0026] Furthermore, if Figure 2 As shown, a first rotating member 2022 and a second rotating member 2023 are disposed in the first driving structure 202, and a first sliding groove 2024 is disposed on the side wall of the first driving structure 202; The first rotating member 2022 includes a first rotating column 20221 that can rotate in the circumferential direction, and the second rotating member 2023 is threadedly connected to the first rotating column 20221; A first slider 20231 is provided on the circumferential side wall of the second rotating member 2023. The first slider 20231 is located in the first slide groove 2024. The first slide groove 2024 is used to convert the circumferential rotation of the first rotating column 20221 into the axial movement of the second rotating member 2023 through the first slider 20231. The second rotating member 2023 is fixedly connected to the guide wire in the nailing and bending adjustment tube 201. The second rotating member 2023 pulls the guide wire through axial movement to adjust the nailing and bending adjustment tube.

[0027] In this way, the matching connection between the first slide groove 2024 and the first slider 20231 can convert the rotational movement of the first rotating member 2022 into the axial movement of the second rotating member 2023, and the second rotating member 2023 is fixedly connected with a guide wire, and then the guide wire is pulled through the axial movement of the second rotating member 2023 to realize the bending operation of the nailing and bending tube 201.

[0028] Further, Figure 3 A schematic diagram schematically shows the structure of a spring tube control device and an anchor control device according to an embodiment of the present invention, as shown in FIG. Figure 3 As shown: The spring tube control device 30 includes a first fixed member 302 and a third rotating member 303; The first fixing member 302 is fixedly connected to the bending pipe control device 20, the third rotating member 303 is inserted into the first fixing member 302, and the third rotating member 303 is fixedly connected to the nail spring tube 301; The third rotating member 303 can move axially and rotate circumferentially relative to the first fixed member 302; A first limiting hole (not shown) is provided on the side wall of the first fixing member 302 , and the first locking member 304 is inserted into the first limiting hole to abut against the third rotating member 303 to limit the movement of the nail spring tube 301 .

[0029] Specifically, the nailing spring tube 301 axially penetrates the third rotating member 303 and the first fixed member 302, and is inserted into the nailing bending tube 201. The third rotating member 303 is fixedly connected to the nailing spring tube 301, and the third rotating member 303 can move, thereby enabling the nailing spring tube 301 to achieve axial movement and circumferential rotation.

[0030] A first limiting hole is provided on the side wall of the first fixing member 302, and the first locking member 304 is threadedly connected to the first limiting block. By screwing in the first locking member 304, the first locking member 304 is abutted against the third rotating member 303, thereby limiting the axial movement and circumferential rotation of the third rotating member 303, thereby achieving the fixation of the nail spring tube 301 and the first fixing member 302.

[0031] Furthermore, if Figure 3 As shown: The anchor control device 40 includes a second fixing member 402 and a fourth rotating member 403; The second fixing member 402 is fixedly connected to the spring tube control device 30, the fourth rotating member 403 is inserted into the second fixing member 402, and the fourth rotating member 403 is fixedly connected to the anchor cable 401; The fourth rotating member 403 can move axially and rotate circumferentially relative to the second fixed member 402 .

[0032] Specifically, the anchor cable 401 axially penetrates the fourth rotating member 403 and the second fixed member 402, and extends into the nailing spring tube 301. The end of the anchor cable 401 is detachably connected with an anchor, which is movably connected to the second fixed member 402 through the fourth rotating member 403, and the fourth rotating member 403 is fixedly connected to the anchor cable. The rotation of the fourth rotating member 403 is controlled to realize the rotational movement of the anchor cable 401, thereby realizing the anchor being nailed into the valve ring tissue.

[0033] Furthermore, if Figure 3 As shown, a first limiting groove 4021 and at least one second limiting groove 4022 are provided on the side wall of the second fixing member 402; The first limiting groove 4021 penetrates the second fixing member 402, and the second limiting groove 4022 is connected to the first limiting groove 4021. The first limiting groove 4021 extends axially, and the second limiting groove 4022 extends circumferentially. A second limiting member (not shown) is radially arranged to penetrate the side wall of the fourth rotating member 403. When the end of the second limiting member is located in the second limiting groove 4022, the fourth rotating member 403 can rotate circumferentially but cannot move axially. When the second limiting member is located in the first limiting groove 4021, the fourth rotating member 403 can move axially but cannot rotate circumferentially.

[0034] Specifically, at least one second limiting groove 4022 is provided. In the solution of the present invention, two second limiting grooves 4022 are provided, and the circumferential extension directions of the two second limiting grooves 4022 are opposite. In this way, the two second limiting grooves 4022 are redundantly provided. When one of the second limiting grooves 4022 fails, the axial movement of the anchor cable 401 can still be limited by rotating the second limiting member into the other second limiting groove 4022.

[0035] At the same time, when the fourth rotating member 403 is inserted into the second fixing member 402 and the second limiting member is located in the second limiting groove 4022, the distance from the end of the fourth rotating member 403 close to the second fixing member 402 to the second fixing member 402 is about 6 mm. When the fourth rotating member 403 is rotated to align the second limiting member with the first limiting groove 4021, the fourth rotating member 403 can move axially. When the fourth rotating member 403 moves axially in the direction close to the second fixing member 402, after the fourth rotating member 403 moves the spacing distance, the fourth rotating member 403 will abut the second fixing member 402, thereby preventing the fourth rotating member 403 from moving excessively. The setting of this distance can prevent the anchor at the end of the anchor cable 401 from excessively penetrating into the valve ring tissue to pierce the inner wall of the heart, thereby preventing cardiac bleeding from affecting the safety of the operation.

[0036] Furthermore, if Figure 1 As shown, a second locking member 1021 is provided on the side wall of the second housing 102, and the second locking member 1021 is inserted into the second housing 102 and abuts against the first driving structure 202, so that the first driving structure 202 and the second housing 102 are fixedly connected; A second slide groove 1011 is provided on the side wall of the first housing 101, and a third limiting hole 1022 is provided on the side wall of the second housing 102. The third locking member 1012 can be inserted into the second slide groove 1011 and is located in the third limiting hole 1022. The third locking member 1012 is slidably connected with the second slide groove 1011 to enable the second housing 102 to move axially relative to the first housing 101. The third locking member 1012 is threadedly connected to the third limiting hole 1022 to fix the first housing 101 and the second housing 102 .

[0037] Specifically, the second locking piece 1021 is threadedly connected to the second shell 102. When the second locking piece 1021 is screwed into the second shell 102 and abuts against the first driving structure 202, the first driving structure 202 is fixedly connected to the second shell 102. At this time, the second shell 102 is slid to make the second shell 102 move axially, thereby driving the first driving structure 202, the spring tube control device 30 and the anchor control device 40 to move axially synchronously, thereby realizing the control of the forward and backward movement of the entire pipeline.

[0038] When the second shell 102 is moved into place, since the third locking member 1012 is threadedly connected to the third limiting hole 1022, the third locking member 1012 can be controlled to rotate so that the third locking member 1012 abuts against and squeezes the first shell 101, thereby achieving a fixed connection between the first shell 101 and the second shell 102.

[0039] Furthermore, if Figure 1 As shown, a third slide groove 1013 is provided on the side wall of the first housing 101, a protrusion 1014 is provided on the inner wall of the third slide groove 1013, and notches 1015 are provided on both sides of the protrusion 1014. The notches 1015 extend a certain distance along the circumferential direction. A second limit block 1023 is provided on the side wall of the second housing 102, and the second limit block 1023 is provided corresponding to the third slide groove 1013; When the second housing 102 is inserted into the first housing 101, the second limit block 1023 is located in the third slide groove 1013. When the second housing 102 moves axially relative to the first housing 101, the second limit block 1023 moves in the third slide groove 1013. When the second limit block 1023 touches the protrusion 1014, the protrusion 1014 limits the movement of the second limit block 1023 to prevent the second housing 102 from continuing to move. The protrusion 1014 is arranged close to the edge of the first housing 101, so as to prevent the second housing 102 from excessively sliding out of the first housing 101. At the same time, when the second shell 102 is inserted, the second limit block 1023 abuts against the protrusion 1014. At this time, a greater force can be used to continue to push the second shell 102, so that the second limit block 1023 squeezes the protrusion 1014, causing the protrusion 1014 to shift toward the direction close to the notch 1015, thereby increasing the distance from the protrusion 1014 to the inner wall of the relative third slide groove 1013, so that the second limit block 1023 can slide in, thereby realizing the installation of the second shell 102. After the second shell 102 enters, the protrusion 1014 resets to continue to prevent the second shell 102 from sliding out of the third slide groove 1013 in the opposite direction.

[0040] Furthermore, if Figure 1 As shown, the nail driving control assembly of the present invention further includes a wire lock control device 50; The wire lock control device 50 is fixedly connected to the housing 10 , and a wire lock spring tube axially penetrates the wire lock control device 50 . The wire lock control device 50 is used to control the wire lock anchor in the wire lock spring tube.

[0041] Specifically, the nailing control component of the present invention is installed with the wire locking control component 70. The wire locking control component 70 can control the first group of wire locking devices to lock the first group of anchors, and the wire locking control device 50 in the nailing control component can control the second group of wire locking devices to lock the second group of anchors. The doctor can synchronously control the wire locking control component 70 and the wire locking control device 50 to synchronously lock the first group of anchors and the second group of anchors. When the doctor controls, the two can be referenced to each other and their respective locking force can be compared, so that the locking forces of the two groups can be made the same or similar through regulation, so that after the anchors are finally locked, the shape of the repaired valve ring tissue is regular, which is conducive to subsequent recovery.

[0042] Furthermore, an observation window 103 is also provided on the shell 10, and the nailing and bending tube 201 and the wire locking spring tube pass through the observation window 103. The observation window 103 is made of a transparent material, and scale lines can be provided on the edge of the observation window 103. When the nailing and bending tube 201 or the wire locking spring tube moves axially, the doctor can check the moving distance of the tube through the observation window 103, which is convenient for the doctor to use.

[0043] Further, Figure 4 A schematic diagram schematically shows the structure of a conveying system according to an embodiment of the present invention, as shown in FIG. Figure 4 As shown, the present invention also provides a delivery system, including the above-mentioned nailing control assembly, and also includes a sheath bending adjustment assembly 60 and a wire locking device control assembly 70; One end of the wire lock control assembly 70 is connected to the sheath tube bending adjustment assembly 60, and the other end is connected to the nailing control assembly. The wire lock spring tube in the wire lock control assembly 70 and the nailing bending adjustment tube in the nailing control assembly extend into the sheath tube in the sheath tube bending adjustment assembly 60; The sheath tube bending adjustment component 60 is used to adjust the bending angle of the sheath tube, and the wire locking device control component 70 is used to control the wire locking device to lock the anchor.

[0044] Specifically, the sheath bending adjustment assembly 60 includes a third housing 601 and a first control member 602. The first control member 602 is disposed on the side of the third housing 601.

The first control component 602 is fixedly connected to the guide wire in the sheath, and the first control component 602 can control the axial movement of the guide wire to pull the guide wire to achieve the bending operation of the sheath. At the same time, the first control component 602 is arranged on the side of the third shell 601 to reduce the overall axial length of the third shell 601, thereby reducing the axial length of the wire locking spring tube and the nailing bending adjustment tube 201 to a certain extent. The shorter the axial length of the tube, the higher the control accuracy of its end, thereby improving the surgical accuracy.

[0045] In this way, through the above-mentioned delivery system, the doctor completes the anchor nailing operation by controlling the nailing control component, and completes the operation of locking the anchor with the wire lock through the wire lock control component 70. When all is completed, the wire lock is removed from the wire lock spring tube, the anchor is removed from the nailing and bending tube 201, and the entire device is withdrawn from the human body to complete the valve ring repair operation.

[0046] To sum up, through the scheme of the present invention, the nailing control assembly includes a bending tube control device 20, a spring tube control device 30 and an anchor control device 40. The bending tube control device 20 can control the axial movement, circumferential rotation and bending of the nailing bending tube 201 therein, the spring tube control device 30 can control the axial movement and circumferential rotation of the nailing spring tube 301 therein, and the anchor control device 40 can control the axial movement and circumferential rotation of the anchor steel cable 401 therein. Through multiple driving modes, each component controls the pipeline separately, which makes it more convenient for doctors to use and the control more precise, thereby improving the safety of surgery.
