Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of valve repair, and in particular to a nailing and bending tube control device, a nailing control component and a conveying 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.

[0021] Figure 1 A schematic diagram schematically shows the structure of a nailing and bending pipe control device according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, a nailing and bending pipe control device of the present invention comprises: The housing 10 is connected to the wire lock control assembly 80; The first driving structure 20 has a nailing and bending adjustment tube 201 disposed therein, the nailing and bending adjustment tube 201 axially penetrates the first driving structure 20, and the first driving structure 20 is fixedly connected to the nailing and bending adjustment tube 201, the first driving structure 20 is axially inserted into the housing 10, and the first driving structure 20 can move axially and rotate circumferentially relative to the housing 10; The second driving structure 30 is inserted into the shell 10 from the side wall of the shell 10. The second driving structure 30 is connected with the first driving structure 20. The second driving structure 30 is used to control the stepping movement of the first driving structure 20 to make the nailing and bending tube 201 move axially.
[0022] In this way, the first driving structure 20 is movably connected to the shell 10, so that the first driving structure 20 can move and control the nailing and bending tube 201 to move rapidly axially and rotate circumferentially. The second driving structure 30 is connected to the first driving structure 20 so that the second driving structure 30 rotates to control the axial stepping movement of the first driving structure 20, so that the nailing and bending tube 201 can move axially in steps. The overall device has multiple driving modes, which can assist doctors in operation and is easy to use.
[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 1 , 2 As shown: The second driving structure 30 includes a rotating shaft 301, a rotating column 302 and a gear 303. The rotating shaft 301 is disposed in the rotating column 302. The rotating column 302 is rotatably connected to the rotating shaft 301. The rotating column 302 is disposed in the gear 303. The gear 303 is fixedly connected to the rotating column 302. The rotating shaft 301 is inserted into the housing 10 and supported by the housing 10 , and the rotating column 302 partially extends out of the housing 10 ; A circumferential rack 202 is provided on the side wall of the first driving structure 20 , and the circumferential rack 202 is meshedly connected with the gear 303 . When the rotating column 302 rotates, the gear 303 moves synchronously to control the axial movement of the first driving structure 20 .
[0024] Specifically, the second driving structure 30 is inserted from the circumferential side wall of the housing 10 and penetrates the housing 10, with both ends exposed from the housing 10, a cylindrical third protrusion 101 is provided on the side wall of the housing 10, and the rotating shaft 301 is inserted into the housing 10 through the center of the third protrusion 101; The second driving structure 30 also includes a first handle 304, which is sleeved on the third protrusion 101. The ends of the rotating shaft 301 and the rotating column 302 are inserted into the first handle 304. The rotating shaft 301 is movably connected to the first handle 304, and the rotating column 302 is fixedly connected to the first handle 304. When the first handle 304 rotates relative to the third protrusion 101, the rotating column 302 rotates synchronously to drive the gear 303 to rotate, while the rotating shaft 301 is stationary.
[0025] A first groove 3021 is provided on the side wall of the rotating column 302 near the end, the outer contour of the rotating column 302 is circular, and the outer contour of the first groove 3021 is a straight line. An insertion groove 3041 is provided on the first handle 304, and the inner wall contour of the insertion groove 3041 matches the outer contour of the rotating column 302. At the same time, a first protrusion 3042 is provided on the inner wall of the insertion groove 3041, and the shape of the first protrusion 3042 matches the shape of the first groove 3021. When the rotating column 302 is connected to the first handle 304, the rotating column 302 is inserted into the insertion groove 3041, and the first protrusion 3042 fits the first groove 3021. When the first handle 304 rotates, the cooperation between the first protrusion 3042 and the first groove 3021 can make the rotating column 302 rotate synchronously, thereby driving the gear 303 thereon to rotate.
[0026] The circumferential rack 202 on the first drive structure 20 is meshedly connected with the gear 303 , and the first drive structure 20 is supported by the gear 303 , so that the housing 10 supports the second drive structure 30 , and the second drive structure 30 supports the overall structure of the first drive structure 20 .
[0027] With such arrangement, the cooperation between the circumferential rack 202 and the gear 303 can convert the linear motion into the circumferential rotational motion, so that the second driving structure 30 will not change position during the axial movement or circumferential rotation of the first driving structure 20 .
[0028] Furthermore, if Figure 1 As shown, the housing 10 includes a first housing 102 and a second housing 103, the first housing 102 is connected to the wire lock control assembly 80, the first driving structure 20 passes through the second housing 103 and the first housing 102 in sequence, and the second driving structure 30 is arranged on the second housing 103; A first locking member 1031 is provided on the second housing 103, and the first locking member 1031 is used to fix the first driving structure 20 to the second housing 103; The second housing 103 is axially movable relative to the first housing 102 .
[0029] Specifically, the first housing 102 is sleeved with the second housing 103, and the second housing 103 is slidably connected to the first housing 102, so that the second housing 103 can move axially relative to the first housing 102; At the same time, a first locking member 1031 is arranged at a position on the side wall of the second shell 103 corresponding to the first driving structure 20. The first locking member 1031 is inserted into the second shell 103 from the outside and abuts against the side wall of the first driving structure 20 to achieve a fixed connection between the two. The first locking member 1031 and the second shell 103 can be arranged to be threadedly connected for easy adjustment.
[0030] Further, a first slide groove 1021 is axially arranged on the side wall of the first housing 102, and a first limiting hole 1032 is arranged on the side wall of the second housing 103. The first limiting member 1022 can pass through the first slide groove 1021 and be inserted into the first limiting hole 1032. The first limiting member 1022 is slidably connected with the first slide groove 1021 to enable the second housing 103 to move axially. The first limiting member 1022 is used to lock the relative movement between the first housing 102 and the second housing 103 .
[0031] Specifically, after the second shell 103 is fixedly connected to the first drive structure 20 through the first locking piece 1031, the second shell 103 and the first drive structure 20 thereon can be moved synchronously by sliding the second shell 103, thereby realizing the axial movement of the nailing and bending tube 201 passing through the first drive structure 20.
[0032] At the same time, the first limiting member 1022 is threadedly connected to the first shell 102, and the first limiting member 1022 passes through the first slide groove 1021 and is inserted into the first limiting hole 1032. When the second shell 103 moves, due to the cooperation between the first limiting hole 1032 and the first limiting member 1022, the first limiting member 1022 moves along the first slide groove 1021. When the second shell 103 moves into place, by tightening the first limiting member 1022, the end of the first limiting member 1022 abuts against the side wall of the first shell 102, thereby realizing the fixed connection between the first shell 102 and the second shell 103.
[0033] Further, Figure 3 Schematically showing an embodiment of the present invention Figure 1 A partial enlarged view of Figure 3 As shown: A second slide groove 1023 is provided on the side wall of the first housing 102, and a first protrusion 1033 is provided on the side wall of the second housing 103. When the first housing 102 is connected to the second housing 103, the first protrusion 1033 is located in the second slide groove 1023; A second protrusion 1024 is provided on the side wall of the second slide groove 1023 . The second protrusion 1024 is provided close to the connection end between the first shell 102 and the second shell 103 . When the first shell 102 and the second shell 103 are connected, the second protrusion 1024 is used to prevent the first protrusion 1033 from moving out of the second slide groove 1023 .
[0034] Specifically, the second protrusion 1024 protrudes from the side wall of the second slide groove 1023, and notches 1025 are provided on the side walls of the second slide groove 1023 on both sides of the second protrusion 1024. The notches 1025 extend a certain distance along the circumference of the first housing 102, so that when the second protrusion 1024 is subjected to a large force, it can be deviated toward the notch 1025 by a certain angle; The outer contour of the second protrusion 1024 is set to an arc shape, and the outer contour of the first protrusion 1033 is also set to an arc shape. When the second shell 103 is inserted into the first shell 102, the first protrusion 1033 touches the second protrusion 1024 to prevent the first protrusion 1033 from continuing to move. At this time, the second shell 103 can be pushed to move with a greater force, thereby causing the second protrusion 1024 to shift. At this time, the distance between the second protrusion 1024 and the second slide groove 1023 becomes larger, allowing the first protrusion 1033 to pass through, thereby realizing the installation of the second shell 103 and the first shell 102. When the second shell 103 moves axially relative to the first shell 102, the first protrusion 1033 can slide in the second slide groove 1023.
[0035] When the two are installed, the weight of the second shell 103 cannot cause the first protrusion 1033 to hit the second protrusion 1024 to offset it, so that the second protrusion 1024 prevents the second shell 103 from sliding out of the first shell 102. When the second shell 103 is controlled to move axially away from the first shell 102, the resistance when the first protrusion 1033 touches the second protrusion 1024 can be felt by the doctor, and the doctor will no longer push the second shell 103 to move further, thereby preventing it from sliding out of the first shell 102.
[0036] Furthermore, if Figure 1 As shown, a bending adjustment component 203 is also provided on the first driving structure 20, and the bending adjustment component 203 is fixedly connected to the guide wire in the nailing bending adjustment tube 201; The bending component 203 can move axially along the first driving structure 20 to pull the guide wire.
[0037] Specifically, the bending adjustment component 203 includes a first rotating member 2031, a second rotating member 2032 and a third sliding groove 2033, the first rotating member 2031 is axially inserted into the first driving structure 20, and the first rotating member 2031 is partially exposed, the first rotating member 2031 is rotatably connected to the first driving structure 20, the second rotating member 2032 is sleeved with the first rotating member 2031, the second rotating member 2032 is threadedly connected to the first rotating member 2031, and the second rotating member 2032 is located in the first driving structure 20; The third slide groove 2033 is arranged on the side wall of the first driving structure 20, and a fourth protrusion 20321 is arranged on the circumferential side wall of the second rotating member 2032. The fourth protrusion 20321 is inserted into the third slide groove 2033. When the first rotating member 2031 rotates, the second rotating member 2032 moves axially due to the cooperation between the fourth protrusion 20321 and the third slide groove 2033. The guide wire in the nailing and bending-adjusting tube 201 is fixedly connected to the second rotating member 2032 . When the second rotating member 2032 moves axially, the guide wire is pulled synchronously, thereby realizing the bending operation of the nailing and bending-adjusting tube 201 .
[0038] Furthermore, if Figure 1 As shown, a nailing and bending pipe control device of the present invention further includes a third driving structure 40; The third driving structure 40 is axially inserted into the housing 10 . A wire locking spring tube is disposed inside the third driving structure 40 . The wire locking spring tube axially penetrates the third driving structure 40 . The third driving structure 40 is used to control the wire locking anchor in the wire locking spring tube.
[0039] Specifically, one end of the shell 10 is connected to the wire locking device control assembly 80, and the wire locking device control assembly 80 can control the first group of wire locking devices to lock the first group of anchors. At the same time, the other end of the shell 10 is also connected to the third driving structure 40, and the third driving structure 40 can control the second group of wire locking devices to lock the second group of anchors. After the nailing and bending tube control device of the present invention is installed with the wire locking device control assembly 80, the doctor can synchronously control the wire locking device control assembly 80 and the third driving structure 40 to synchronously lock the first group of anchors and the second group of anchors. During the locking process of the two groups of anchors, the doctor can accurately detect the size of the locking force in the two groups of wire locking devices, and then lock the anchors with the same or similar locking force through comparison of the two groups, thereby making the shape of the valve repair regular and improving the subsequent recovery effect.
[0040] The third driving structure 40 includes a first control component 401 and a second control component 402. The first control component 401 is fixedly connected to the wire locking spring tube, and the first control component 401 can control the axial movement and axial rotation of the wire locking spring tube. The second control component 402 is fixedly connected to the wire locking steel cable. The wire locking steel cable is arranged in the wire locking spring tube, and the end of the wire locking steel cable is detachably connected with a wire locker. The second control component 402 can control the axial movement and circumferential rotation of the wire locking steel cable, thereby realizing the operation of the wire locking anchor.
[0041] Furthermore, if Figure 1 As shown, an observation window 104 is provided on the shell 10, and the nailing and bending adjustment tube 201 and the wire locking spring tube pass through the observation window 104. The observation window 104 is made of a transparent material, and a scale line can be provided at the axial edge of the observation window 104. The specific forward distance of the nailing and bending adjustment tube 201 or the wire locking spring tube can be detected through the scale line and the observation window, which is convenient for doctors to use.
[0042] Further, Figure 4 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 4 As shown, the present invention also provides a nailing control assembly, including the nailing bending pipe control device mentioned above, and also including a nailing spring pipe control device 50 and an anchor control device 60; The nailing spring tube is arranged in the nailing bending tube 201, the anchor is arranged in the nailing spring tube, the nailing spring tube control device 50 is used to control the axial movement and circumferential rotation of the nailing spring tube therein, the anchor control device 60 is used to control the axial movement and circumferential rotation of the anchor therein, and the nailing control component is used to control the anchor to be nailed into the valve ring tissue.
[0043] With such arrangement, the nailing bending tube control device and the nailing spring tube control device 50 are used to control the nailing bending tube 201 and the nailing spring tube to move to the nailing position. At this time, the anchor control device 60 is used to control the anchor to extend out of the nailing spring tube and screw into the valve ring tissue to complete the nailing operation. Each component is controlled by a corresponding device, and the control is more flexible and precise, thereby ensuring the safety of the operation.
[0044] Further, Figure 5 A schematic diagram schematically shows the structure of a conveying system according to an embodiment of the present invention, as shown in FIG.

[0045] Specifically, the sheath bending adjustment assembly 70 includes a third shell 701 and a third control component 702. The third control component 702 is arranged on the side of the third shell 701. One end of the third shell 701 is connected to the sheath, and the other end is connected to the wire locking control assembly 80. The third control component 702 is connected to the guide wire in the sheath. The third control component 702 can move axially to pull the guide wire and thereby realize the bending operation of the sheath.
[0046] The wire locking device control assembly 80 includes a fourth shell 801, a fourth control component 802 and a multi-lumen tube 803. The multi-lumen tube 803 is connected to one end of the fourth shell 801, and the other end of the fourth shell 801 is connected to the nailing control assembly. The fourth control component 802 is arranged on the side of the fourth shell 801. The wire locking device spring tube axially penetrates the inside of the fourth control component 802, and the wire locking device spring tube penetrates into the multi-lumen tube 803. When the wire locking device control assembly 80 is connected to the sheath bending adjustment assembly 70, the multi-lumen tube 803 extends into the sheath.
[0047] The third control component 702 is arranged on the side of the third shell 701, and the fourth control component 802 is arranged on the side of the fourth shell 801. Such an arrangement can shorten the overall length of the third shell 701 and the fourth shell 801, thereby shortening the length of the thread locking spring tube and the nailing and bending tube 201 that penetrate through the tube. After the tube is shortened, the control accuracy of the control device connected to its end is improved, thereby improving the completeness of the operation.
[0048] Through the above-mentioned delivery system, the doctor completes the anchor nailing operation by controlling the nailing control device, and completes the operation of locking the anchor with the wire lock through the wire lock control assembly 80. When all is completed, the wire lock is removed from the wire lock spring tube, the anchor is removed from the nailing spring tube, and the entire device is withdrawn from the human body to complete the valve ring repair surgery.
[0049] To summarize, the nailing and bending pipe control device includes a first driving structure 20 and a second driving structure 30. The first driving structure 20 is axially arranged on the shell 10. The first driving structure 20 can move axially and rotate circumferentially relative to the shell 10 to realize the rapid operation of the nailing and bending pipe 201. At the same time, the second driving structure 30 is circumferentially arranged on the side wall of the shell 10, which is connected with the first driving structure 20 and can realize the stepping movement of the nailing and bending pipe 201 by controlling the stepping movement of the first driving structure 20; at the same time, the second driving structure 30 includes a gear 303, and a circumferential rack 202 is arranged on the side wall of the first driving structure 20. When the gear 303 rotates, the first driving structure 20 can be moved axially through the cooperation of the gear 303 and the circumferential rack 202. At the same time, when the first driving structure 20 moves axially or rotates circumferentially, the second driving structure 30 will not move axially. Through the cooperation of the gear 303 and the circumferential rack 202, the disadvantage that when the two are threadedly matched, one side moves and the other side also changes position is solved.
