Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of valve repair, and particularly relates to a suture passer control device and a delivery system. Background Art
[0002] The heart valve is a checkpoint between different cardiovascular structures, which can only open and close in a specific 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 the directional flow of blood circulation from the left atrium to the left ventricle and a certain blood flow rate. Blood flows from the left atrium through the mitral valve into the left ventricle, and then is pumped from the left ventricle into the aorta and flows to the whole body. When the mitral valve opens, blood flows from the left atrium into the left ventricle; then the mitral valve closes to ensure that when the left ventricle contracts and pumps blood into the aorta, the blood will 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, which is mitral regurgitation.
[0003] Mitral regurgitation is the most common heart valve disease globally. The regurgitation reduces the blood flow rate to various parts of the body. To compensate, the heart will try to pump blood more forcefully, increasing the heart burden. Patients with severe mitral regurgitation may experience various debilitating symptoms, such as shortness of breath, palpitations, dizziness, and fatigue. These patients are at risk of poor quality of life, significantly limited activities, repeated hospitalizations due to heart failure, and increased mortality. Chronic severe mitral regurgitation is usually accompanied by heart failure and can lead to death if left untreated.
[0004] Currently, in valve repair surgery, the control mode of the device for controlling the suture passer to lock the anchor is relatively simple, and it can only achieve 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 locking force is mostly determined by the doctor's experience, resulting in poor final valve repair effect, irregular valve shape, and affecting the subsequent recovery effect.

Detailed implementation manners
[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.
[0049] 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", "the", and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0050] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present invention are described from the angles shown in the drawings, and should not be construed as limitations on the embodiments of the present invention. In addition, in the context, it should also be understood that when it is mentioned that one component is formed "on" or "under" another component, it can not only be directly formed "on" or "under" another component, but also be indirectly formed "on" or "under" another component through an intermediate component.
[0051] Figure 1 A schematic structural diagram of a thread-locking device control device showing an embodiment of the present invention is as Figure 1 shown. A thread-locking device control device of the present invention includes:
[0052] A first housing 10, internally connected with a multi-chamber tube 40, and the multi-chamber tube 40 extends out from one end of the first housing 10;
[0053] A thread-locking device spring tube 20, which extends into the first housing 10 from the outside and extends into the multi-chamber tube 40;
[0054] A control assembly 30, which is arranged on the side of the first housing 10, and the thread-locking device 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 fixedly connect the first adjustment structure 301 with the thread-locking device spring tube 20. When the first adjustment structure 301 is fixedly connected with the thread-locking device spring tube 20, the first adjustment structure 301 is used to control the step rotation of the thread-locking device spring tube 20;
[0055] The second adjustment structure 303 is fixedly connected with the thread-locking device spring tube 20, and the second adjustment structure 303 is used to control the axial movement and circumferential rotation of the thread-locking device spring tube 20.
[0056] Specifically, a thread-locking device is arranged inside the thread-locking device spring tube 20. After the anchor nail is driven into the valve tissue, the thread-locking device rotates itself to make the two anchor nails approach each other, so as to reduce the valve annulus and achieve the repair effect.
[0057] During repair, the internal space of the heart valve cannot be clearly imaged by relevant imaging equipment. When the thread-locking device is locked, it is necessary to rely on the doctor's experience to control the locking force, and the surgical balance of valve repair is poor. It is impossible to ensure that the locking forces of multiple groups of anchor nails are the same or similar, resulting in an irregular valve shape and affecting the subsequent recovery effect;
[0058] In this solution, the first adjustment structure 301 is sleeved on the wire-locking spring tube 20. It can control the wire-locking spring tube 20 to perform step-by-step rotation through self-rotation. Through the step-by-step rotation, the doctor can perceive the rotation angle of the wire-locking spring tube 20, and the device itself provides assistance for the doctor's surgical operation to achieve a more precise wire-locking operation.
[0059] Meanwhile, the control component 30 is arranged on the side of the first housing 10, which can reduce the axial length of the first housing 10. Then, when both ends of it are used for the pipeline to pass through, the overall length of the pipeline can be reduced to a certain extent. And when the pipeline is shorter, the control accuracy of the control device used to control the movement of the pipeline end is higher, thereby improving the surgical accuracy.
[0060] Furthermore, Figure 2 The schematic diagram of the first rotating part showing an embodiment of the present invention is as Figure 1 、 2 shown:
[0061] The first adjustment structure 301 includes a first rotating part 3011 and a second rotating part 3012;
[0062] The first rotating part 3011 is fixedly connected to the first housing 10. The first rotating part 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 part 3012 is sleeved on the limiting column 30112, and the bottom of the second rotating part 3012 contacts the top of the fixed base 30111;
[0063] A plurality of first limiting grooves 30113 are arranged on the top surface of the fixed base 30111, and a plurality of first limiting blocks 30121 are arranged on the bottom surface of the second rotating part 3012. The first limiting blocks 30121 are arranged corresponding to the first limiting grooves 30113;
[0064] When the second rotating part 3012 rotates forward 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 part 3012 rotates backward relative to the limiting column 30112, the first limiting groove 30113 prevents the first limiting block 30121 from moving.
[0065] Specifically, the first limiting grooves 30113 are arranged on the top surface of the fixed base 30111, and the first limiting blocks 30121 are arranged on the bottom surface of the second rotating part 3012. When the second rotating part 3012 is sleeved on the limiting column 30112, the first limiting blocks 30121 can be inserted into the first limiting grooves 30113;
[0066] A plurality of first limiting grooves 30113 and first limiting blocks 30121 are provided, and they are circumferentially and uniformly distributed around the center of the limiting column 30112. When the second rotating member 3012 rotates positively 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 at 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 into the next first limiting groove 30113, through the re - reset movement of the reset device, the first limiting block 30121 impacts the first limiting groove 30113, and this impact will produce a sound and can be heard by the doctor.
[0067] By specially designing the number of the first limiting grooves 30113 that are circumferentially and uniformly distributed, for example, setting 12 first limiting grooves 30113, when the second rotating member 3012 rotates positively, each time the first limiting block 30121 impacts the first limiting groove 30113, it means that the locking wire spring tube 20 rotates by 30°. In this way, it can assist the doctor to accurately control the tightening force of the locking wire spring tube 20, which is convenient for the doctor to use. At the same time, when the doctor needs to tighten multiple groups of anchor bolts, by referring to the rotation angle of each group of locking wire spring tubes 20, the tightening forces of multiple groups of anchor bolts can be made the same or similar, so that the shape of the finally repaired valve is regular, and the subsequent recovery effect of the valve is improved.
[0068] Furthermore, Figure 3 、 4 Schematically showing the structural schematic diagrams of the second rotating member from different perspectives of an embodiment of the present invention, as Figure 1-4 shown:
[0069] The second rotating member 3012 includes a second housing 30122, a rotating block 30123, and an elastic member 30124;
[0070] The limiting column 30112 is arranged inside the rotating block 30123 and the elastic member 30124. The rotating block 30123 and the elastic member 30124 are arranged inside the second housing 30122, and the second housing 30122 is circumferentially limited to the rotating block 30123;
[0071] A limiting plane 30125 is further arranged inside the second housing 30122. The elastic member 30124 is arranged between the limiting plane 30125 and the rotating block 30123, and the limiting column 30112 passes through the limiting plane 30125;
[0072] 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.
[0073] Specifically, the first limiting groove 30113 includes a first side wall 30114 and a second side wall 30115. The first side wall 30114 is inclined. 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 extends.
[0074] When the doctor controls the rotation of the second rotating member 3012, the first limiting block 30121 moves along the inclined first side wall 30114 to the next first limiting groove 30113, causing the first limiting block 30121 and the rotating block 30123 to gradually move upward, and the elastic member 30124 to be gradually compressed. When the first limiting block 30121 moves to the junction of the first side wall 30114 and the next second side wall 30115 and then moves further, the first limiting block 30121 is no longer limited, and the elastic member 30124 extends and resets, so that the first limiting block 30121 pops into the first limiting groove 30113 and impacts the first side wall 30114 and the second side wall 30115, making a sound and being perceived by the doctor, realizing the control of the locking force.
[0075] Further, the second side wall 30115 abuts against the side of the first limiting block 30121 to prevent the reverse rotation of the rotating block 30123. When the first limiting block 30121 is located in the first limiting groove 30113 and moves reversely relative to the limiting column 30112, the first limiting block 30121 touches the second side wall 30115 and is limited by the second side wall 30115, thereby preventing the reverse rotation of the wire locking spring tube 20 of the wire locking device, and avoiding the loosening of the wire locking device caused by external reasons such as accidental touch after the wire locking device is tightened in place, so that the tightening force cannot be controlled.
[0076] Further, the rotating block 30123 is circumferentially limited with the second housing 30122. Specifically:
[0077] A second limiting groove 30126 is provided on the side wall of the second housing 30122, and the second limiting groove 30126 penetrates through the second housing 30122.
[0078] A second limiting block 30127 is provided 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, and the second limiting groove 30126 limits the circumferential movement of the second limiting block 30127.
[0079] The axial length of the second limiting groove 30126 is greater than that of the first limiting groove 30113. When the second limiting block 30127 axially moves 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 reverse direction relative to the fixed base 30111.
[0080] Specifically, a second limiting groove 30126 is provided on the side of the second housing 30122, and a second limiting block 30127 is provided on the side of the rotating block 30123. By passing through the second limiting groove 30126, the circumferential limiting between the rotating block 30123 and the second housing 30122 is realized, so that when the doctor controls the movement of the second housing 30122, the rotating block 30123 can move synchronously.
[0081] When the doctor controls the second housing 30122 to rotate excessively, resulting in too large a locking force of the wire locking device, in order to avoid the inability to rotate in the reverse direction to correct the locking force of the wire locking device, in this solution, the axial length of the second limiting groove 30126 is set to be greater than that of the first limiting groove 30113;
[0082] In the initial state, the first limiting block 30121 is located in the first limiting groove 30113 and the reverse movement of the first limiting block 30121 is restricted by the second side wall 30115. When the forward rotation is excessive, by controlling the second limiting block 30127 to slide in the second limiting groove 30126, the rotating block 30123 is lifted, so that the first limiting block 30121 moves out of the first limiting groove 30113. At this time, the second limiting block 30127 can be controlled to rotate in the reverse direction, so that the rotating block 30123 and the second housing 30122 rotate in the reverse direction as a whole, realizing the correction of the excessive locking force.
[0083] Furthermore, as shown in Figure 1 、 3 、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 circumferentially along the wire locking device spring tube 20;
[0084] The diameter of the figure surrounded by the plurality of clamping members 30128 is greater than the diameter of the wire locking device spring tube 20;
[0085] The locking member 302 sleeved on the plurality of clamping members 30128. When the locking member 302 axially moves away from the second housing 30122, the locking member 302 makes the plurality of clamping members 30128 approach each other to clamp the wire locking device spring tube 20.
[0086] Specifically, the opening diameter of the locking member 302 is smaller than the diameter of the figure enclosed by the plurality of 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 plurality of clamping members 30128 when clamping the wire locking spring tube 20, so that when the locking member 302 axially moves away from the second housing 30122, the plurality of clamping members 30128 can be gradually gathered, achieving the effect of clamping the wire locking spring tube 20.
[0087] The locking member 302 can be threadedly connected to the top of the second housing 30122, and the locking member 302 axially moves relative to the second housing 30122 by rotating the locking member 302. The plurality of clamping members 30128 are elastic. When the locking member 302 no longer clamps the clamping members 30128, the clamping members 30128 can be reset to release the wire locking spring tube 20, realizing the rapid axial movement and circumferential rotation of the second adjustment structure 303 to control the wire locking spring tube 20.
[0088] Furthermore, as Figure 1 、 3 shown in FIG. 4, a third limiting block 30129 is further provided in the second housing 30122. The third limiting block 30129 is provided between the limiting plane 30125 and the top of the second housing 30122;
[0089] The third limiting block 30129 is fixedly connected to the limiting column 30112. When the elastic member 30124 extends, the limiting plane 30125 prevents the axial movement of the third limiting block 30129.
[0090] Specifically, the limiting column 30112 penetrates through the limiting plane 30125, the third limiting block 30129 sleeves 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 through which the limiting column 30112 penetrates, so that when the elastic member 30124 extends, it pushes the fixed base 30111 to move away from the limiting plane 30125, thereby driving the limiting column 30112 fixedly connected to the fixed base 30111 to move together. The third limiting block 30129 is sleeved on the limiting column 30112. When the limiting column 30112 moves, it drives the third limiting block 30129 to move and hit the limiting plane 30125, preventing the first rotating member 3011 from sliding out of the second rotating member 3012.
