Description

Technical Field

[0001] The present invention relates to the technical field of valve repair, and in particular to a wire lock control device 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 locking wire to lock the anchor is relatively simple, and can only realize the movement and rotation of the tube. The device itself cannot provide other assistance or reference for the doctor's locking operation. When locking, the doctor mostly relies on his experience to determine the locking force, resulting in poor final valve repair effect and irregular valve shape, which affects the subsequent recovery effect.

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 wire lock control device according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, a wire lock control device of the present invention comprises: The first shell 10 has a multi-lumen tube 40 connected thereto, and the multi-lumen tube 40 extends from one end of the first shell 10; The wire lock spring tube 20 extends from the outside into the first housing 10 and into the multi-lumen tube 40; The control assembly 30 is arranged at the side of the first housing 10. The wire locking spring tube 20 passes through the control assembly 30. The control assembly 30 includes a first adjustment structure 301, a locking member 302, and a second adjustment structure 303. The locking member 302 is used to fix the first adjustment structure 301 with the wire locking spring tube 20. When the first adjustment structure 301 is fixedly connected with the wire locking spring tube 20, the first adjustment structure 301 is used to control the stepping rotation of the wire locking spring tube 20. The second adjustment structure 303 is fixedly connected to the wire locking spring tube 20 , and the second adjustment structure 303 is used to control the axial movement and circumferential rotation of the wire locking spring tube 20 .

[0022] Specifically, a wire locker is provided in the wire locker spring tube 20. When the anchors are driven into the valve tissue, the wire locker rotates to bring the two anchors closer to each other, thereby shrinking the valve ring and achieving a repair effect.

[0023] During repair, the internal space of the heart valve cannot be clearly visualized by relevant imaging equipment. When the locking device is locked, the locking force must be controlled based on the doctor's experience. The surgical balance of valve repair is poor, and the locking force of multiple sets of anchors cannot be guaranteed to be consistent or similar, resulting in an irregular valve shape, affecting the subsequent recovery effect. In this solution, a first adjustment structure 301 is provided to sleeve the wire locking spring tube 20, which can control the wire locking spring tube 20 to rotate in steps by self-rotation. The doctor can sense the rotation angle of the wire locking spring tube 20 through the step-by-step rotation, and the device itself can assist the doctor's surgical operation, thereby achieving a more precise wire locking operation.

[0024] At the same time, setting the control component 30 on the side of the first shell 10 can reduce the axial length of the first shell 10, and when its two ends are used for pipelines to pass through, the overall length of the pipeline can be reduced to a certain extent. When the pipeline is shorter, the control device at its end used to control the movement of the pipeline has higher control accuracy, thereby improving the surgical accuracy.

[0025] Further, Figure 2 A schematic diagram schematically shows the structure of the first rotating member of an embodiment of the present invention, as shown in FIG. Figure 1 , 2 As shown: The first adjustment structure 301 includes a first rotating member 3011 and a second rotating member 3012; The first rotating member 3011 is fixedly connected to the first housing 10, and the first rotating member 3011 includes a fixed base 30111 and a limiting column 30112, the limiting column 30112 is fixedly connected to the top of the fixed base 30111, the second rotating member 3012 is sleeved on the limiting column 30112, and the bottom of the second rotating member 3012 is in contact with the top of the fixed base 30111; A plurality of first limiting grooves 30113 are provided on the top surface of the fixed base 30111, and a plurality of first limiting blocks 30121 are provided on the bottom surface of the second rotating member 3012, wherein the first limiting blocks 30121 are provided corresponding to the first limiting grooves 30113; When the second rotating member 3012 rotates forwardly relative to the limiting column 30112, the first limiting block 30121 can move from one first limiting groove 30113 to the next first limiting groove 30113 along the rotation direction. When the second rotating member 3012 rotates backward relative to the limiting column 30112, the first limiting groove 30113 prevents the first limiting block 30121 from moving.

[0026] Specifically, a first limiting groove 30113 is provided on the top surface of the fixed base 30111, and a first limiting block 30121 is provided on the bottom surface of the second rotating member 3012. When the second rotating member 3012 is sleeved on the limiting column 30112, the first limiting block 30121 can be inserted into the first limiting groove 30113; There are multiple first limiting grooves 30113 and first limiting blocks 30121, which are evenly distributed circumferentially with the center of the limiting column 30112 as the center. When the second rotating member 3012 rotates forwardly relative to the limiting column 30112, the first limiting block 30121 can move circumferentially from one first limiting groove 30113 to the next first limiting groove 30113. A reset device is provided on the top of the first limiting block 30121. When the first limiting block 30121 moves from one first limiting groove 30113 to the next first limiting groove 30113, the reset device goes through an initial reset state, a compressed state and a re-reset state. When the first limiting block 30121 moves to the next first limiting groove 30113, the re-reset movement of the reset device causes the first limiting block 30121 to hit the first limiting groove 30113. The collision will make a sound and can be heard by the doctor.

[0027] By specially designing the number of first limit grooves 30113 evenly distributed along the circumference, such as setting 12 first limit grooves 30113, when the second rotating member 3012 rotates forward, each time the first limit block 30121 hits the first limit groove 30113, it means that the thread locking spring tube 20 has rotated 30°. In this way, the doctor can be assisted to accurately control the tightening force of the thread locking spring tube 20, which is convenient for the doctor to use. At the same time, when the doctor needs to lock multiple groups of anchors, by referring to the rotation angle of each group of thread locking spring tube 20, the locking force of multiple groups of anchors can be made the same or similar, thereby making the shape of the valve after the final repair regular and improving the subsequent valve recovery effect.

[0028] Further, Figure 3 , 4 The schematic diagrams schematically show the structure of the second rotating member from different viewing angles in one embodiment of the present invention, such as Figure 1-4 As shown: The second rotating member 3012 includes a second housing 30122 , a rotating block 30123 and an elastic member 30124 ; The limiting column 30112 is disposed in the rotating block 30123 and the elastic member 30124. The rotating block 30123 and the elastic member 30124 are disposed in the second housing 30122. The second housing 30122 and the rotating block 30123 are circumferentially limited. A limiting plane 30125 is further provided in the second housing 30122, the elastic member 30124 is provided between the limiting plane 30125 and the rotating block 30123, and the limiting column 30112 passes through the limiting plane 30125; A first limiting block 30121 is provided at the bottom of the rotating block 30123 . When the first limiting block 30121 moves to the next first limiting groove 30113 , the elastic member 30124 is used to rotate the rotating block 30123 .

[0029] Specifically, the first limiting groove 30113 includes a first side wall 30114 and a second side wall 30115. The first side wall 30114 is tilted. When the rotating block 30123 rotates forward relative to the fixed base 30111, the first limiting block 30121 abuts against the first side wall 30114, so that the rotating block 30123 compresses the elastic member 30124. When the first limiting block 30121 moves to the next first limiting groove 30113, the elastic member 30124 stretches. When the doctor controls the second rotating member 3012 to rotate, the first limit block 30121 moves along the inclined first side wall 30114 to the next first limit groove 30113, causing the first limit block 30121 and the rotating block 30123 to gradually move upward, and the elastic member 30124 is gradually compressed. When the first limit block 30121 moves to the junction of the first side wall 30114 and the next second side wall 30115 and moves further, the first limit block 30121 is no longer limited, and the elastic member 30124 stretches and resets, so that the first limit block 30121 pops out into the first limit groove 30113 and hits the first side wall 30114 and the second side wall 30115, making a sound that can be perceived by the doctor, thereby achieving control of the locking force.

[0030] Furthermore, the second side wall 30115 abuts against the side of the first limit block 30121 to prevent the rotating block 30123 from rotating in the opposite direction. When the first limit block 30121 is located in the first limit groove 30113 and moves in the opposite direction relative to the limit column 30112, the first limit block 30121 touches the second side wall 30115 and is limited by the second side wall 30115, thereby preventing the wire lock spring tube 20 from rotating in the opposite direction, thereby preventing the wire lock from loosening due to external reasons such as accidental touch after the wire lock is locked in place, resulting in the inability to control the tightening force.

[0031] Furthermore, the rotating block 30123 and the second housing 30122 are circumferentially limited, which is specifically: A second limiting groove 30126 is provided on the side wall of the second housing 30122, and the second limiting groove 30126 penetrates the second housing 30122; A second limiting block 30127 is disposed on the side wall of the rotating block 30123. The second limiting block 30127 extends out of the second housing 30122 through the second limiting groove 30126. The second limiting groove 30126 limits the circumferential movement of the second limiting block 30127. The axial length of the second limiting groove 30126 is greater than the axial length of the first limiting groove 30113. When the second limiting block 30127 moves axially away from the first limiting groove 30113, the first limiting block 30121 extends out of the first limiting groove 30113, and the second rotating member 3012 can rotate in the opposite direction relative to the fixed base 30111.

[0032] Specifically, a second limiting groove 30126 is provided on the side of the second shell 30122, and a second limiting block 30127 is provided on the side of the rotating block 30123. The second limiting groove 30126 passes through the second limiting groove 30126 to achieve mutual circumferential limitation of the rotating block 30123 and the second shell 30122, so that when the doctor controls the movement of the second shell 30122, the rotating block 30123 can move synchronously.

[0033] When the doctor controls the second housing 30122 to rotate excessively so that the locking force of the thread lock is too large, in order to avoid the inability to reversely rotate so that the locking force of the thread lock is corrected, the present solution sets the axial length of the second limiting groove 30126 to be greater than the axial length of the first limiting groove 30113; In the initial state, the first limit block 30121 is located in the first limit groove 30113 and is restricted by the second side wall 30115 from reverse movement. When the forward rotation is excessive, the second limit block 30127 is controlled to slide in the second limit groove 30126 to lift the rotating block 30123, so that the first limit block 30121 moves out of the first limit groove 30113. At this time, the second limit block 30127 can be controlled to rotate in the reverse direction, so that the rotating block 30123 and the second shell 30122 rotate in the reverse direction as a whole, thereby correcting the excessive locking force.

[0034] Furthermore, if Figure 1 , 3 As shown in , 4, a plurality of clamping members 30128 are provided on the top of the second housing 30122, the clamping members 30128 are fixedly connected to the second housing 30122, and the plurality of clamping members 30128 are arranged along the circumference of the wire lock spring tube 20; The diameter of the pattern surrounded by the plurality of clamping members 30128 is greater than the diameter of the wire lock spring tube 20; The locking member 302 is sleeved with the plurality of clamping members 30128 . When the locking member 302 moves axially in a direction away from the second housing 30122 , the locking member 302 brings the plurality of clamping members 30128 closer to each other to clamp the wire locking spring tube 20 .

[0035] Specifically, the opening diameter of the locking member 302 is smaller than the diameter of the figure enclosed by the multiple clamping members 30128 in the initial state, and the opening diameter of the locking member 302 is larger than the diameter of the figure enclosed by the multiple clamping members 30128 when they are clamping the wire locking spring tube 20, so that when the locking member 302 moves axially away from the second shell body 30122, the multiple clamping members 30128 can be gradually gathered together to achieve the effect of clamping the wire locking spring tube 20.

[0036] The locking piece 302 can be connected to the top thread of the second shell body 30122. The locking piece 302 can be rotated to make the locking piece 302 move axially relative to the second shell body 30122. The multiple clamping pieces 30128 are elastic. When the locking piece 302 no longer clamps the clamping pieces 30128, the clamping pieces 30128 can be reset to loosen the wire locking spring tube 20, thereby realizing the second adjustment structure 303 controlling the rapid axial movement and circumferential rotation of the wire locking spring tube 20.

[0037] Furthermore, if Figure 1 , 3As shown in FIG. 4 , a third limit block 30129 is further provided in the second housing 30122 , and the third limit block 30129 is provided between the limit plane 30125 and the top of the second housing 30122 ; The third limiting block 30129 is fixedly connected to the limiting column 30112 , and when the elastic member 30124 is extended, the limiting plane 30125 prevents the third limiting block 30129 from axially moving.

[0038] Specifically, the limiting column 30112 passes through the limiting plane 30125, and the third limiting block 30129 is sleeved on the limiting column 30112, and the diameter of the third limiting block 30129 is larger than the diameter of the opening on the limiting plane 30125 for the limiting column 30112 to pass through, so that when the elastic member 30124 extends, it pushes the fixed base 30111 to move away from the limiting plane 30125, and then drives the limiting column 30112 fixedly connected to the fixed base 30111 to move together, and the third limiting block 30129 is sleeved on the limiting column 30112.
