Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a puncture-friendly repair system. Background Technology

[0002] The foramen ovale is a physiological passage in the atrial septum of the heart during embryonic development. Since the fetus lacks pulmonary circulation, oxygenated blood from the umbilical cord flows from the right atrium into the left atrium through the foramen ovale. After birth, as pulmonary circulation develops, left atrial pressure increases, causing the secondary and primary septa to approach and fuse, gradually forming a permanent atrial septum. However, in some individuals, this fusion fails, resulting in patent foramen ovale (PFO). In patients with PFO, the remaining slit-like abnormal passage between the primary and secondary septa acts like a functional valve. Because the blood pressure in the left atrium is higher than in the right atrium, blood may flow from the left atrium into the right atrium through the foramen ovale. Prolonged blood flow from the left atrium to the right atrium leads to an increase in right atrial blood volume, causing right ventricular hypertrophy and increased pulmonary blood volume.

[0003] Patent CN201811177715.9 discloses a suturing device. The technical defects of this solution are as follows: because the primary septum is thinner and more flexible than the secondary septum, the primary septum is not easy to puncture. At the same time, the tubular catheter has a large diameter due to the puncture catheter inside, and there is no corresponding reaction force to restrict the primary septum, making it even more difficult to puncture the primary septum. The primary septum will only be pushed towards the left atrium by the tubular catheter, which will damage the primary septum tissue, affect the normal heartbeat, and result in high surgical risk and low feasibility.

[0004] Patent CN202210546721.7 provides a repair system. The technical defect of this solution is that when the repair unit is connected to the double puncture structure, if the repair unit is a flexible component, the actual repair effect is not good and it is prone to breakage after long-term use. If the repair unit is a rigid component, it is easy to interfere with the primary and secondary septa during the movement of the double puncture structure, resulting in damage to intracardiac tissue and causing secondary injury.

[0005] In summary, the existing technology has the following problems that urgently need to be solved: First, the puncture structure is difficult to puncture accurately because it does not receive the corresponding support force during puncture; Second, the repair unit is placed outside the puncture structure, resulting in poor repair effect or interference. Summary of the Invention

[0006] This application is made in view of the above and other ideas.

[0007] One of the purposes of this application is to overcome the shortcomings of the prior art and to provide a repair system that facilitates puncture, addressing the issues of unreasonable puncture structure design and unreasonable repair unit design.

[0008] The objective of this invention is achieved through the following solution: A puncture-friendly repair system includes at least a double-puncture structure, a grasping device, and a repair component. The repair component is at least partially fitted within the double-puncture structure. During the repair process, the double-puncture structure can puncture two tissues with gaps back and forth. The grasping device is positioned on the first puncture starting point side of the double-puncture structure and abuts against the tissue, providing support for the tissue punctured by the double-puncture structure in the second puncture. Furthermore, the double-puncture structure delivers the repair component to the target position during the puncture process, and the repair component connects the two punctured tissues to reduce or eliminate the gap.

[0009] The objective of this invention can also be further achieved through the following technical solutions: Furthermore, the repair system also includes a guide connected to the distal end of the repair component.

[0010] Furthermore, the dual-puncture structure includes a first puncture member and a second puncture member; and the second puncture member is sleeved inside the first puncture member.

[0011] Furthermore, the distal end of the guide is pointed, and the guide is positioned at the distal end of the double-puncture structure during pre-installation.

[0012] Furthermore, when the dual-puncture structure performs the first puncture, the first puncture member pushes the guide member to complete the puncture; when the dual-puncture structure performs the second puncture, the first puncture member or the second puncture member pushes the guide member to complete the puncture.

[0013] Furthermore, the guide is coil-shaped or spherical, and is pre-installed within the double-puncture structure, and is located at the distal end of the second puncture member.

[0014] Furthermore, the first and second punctures of the dual-puncture structure are both completed by the first puncture member; and after the second puncture is completed, the second puncture member pushes out the guide member.

[0015] Furthermore, the repair system also includes a stabilizing structure connected to the dual-puncture structure. The stabilizing structure includes a fixing member and a connecting member. When the dual-puncture structure performs a second puncture, the connecting member is pulled to ensure the puncture angle.

[0016] Furthermore, the repair system also includes a retrieval catheter, in which the dual-puncture structure and the stabilizing structure are pre-installed and fitted together; and the distal end of the retrieval catheter is pointed, so that the retrieval catheter will pass through the tissue that was punctured for the first time in order to retrieve the dual-puncture structure.

[0017] Furthermore, the capturing device includes a capturing rod and a capturing ring connected to the distal end of the capturing rod; and, in its natural state, the capturing rod and the capturing ring are not on the same plane.

[0018] Furthermore, before the second puncture of the double-puncture structure, the proximal portion of the capture circle abuts against the tissue; and, in the projection direction of the capture circle, the guide is located within the capture circle.

[0019] Furthermore, the repair component includes a locking unit and a connecting unit; and after the second puncture of the dual-puncture structure is completed, the second puncture member and / or the first puncture member are retrieved, and the entire guide member and part of the connecting unit are exposed in the body.

[0020] Furthermore, the far end of the capture circle captures the guide component. During the process of pulling the capture rod towards the near end, the connecting unit passes through the first puncture point and the second puncture point in sequence and moves towards the near end. When the locking unit is connected to or in contact with both the first puncture point and the second puncture point, the repair component is rotated until the locking unit separates from the repair component.

[0021] Furthermore, the stabilizing structure is connected to the first puncture member.

[0022] Furthermore, the connector is a flexible component and does not have a predetermined shape.

[0023] Furthermore, the locking unit is made of metal.

[0024] Furthermore, when the double-puncture structure performs a second puncture, the tissue subjected to the second puncture receives a puncture force from the double-puncture structure or the guide and a supporting force from the capture ring. The puncture force is directed towards the proximal end, and the supporting force is directed towards the distal end, thereby confining the tissue subjected to the second puncture between the two and stably securing it, thus successfully achieving the second puncture.

[0025] Furthermore, during the first puncture, the dual-puncture structure, carrying the guide, enters the left atrium from the right atrium; during the second puncture, the dual-puncture structure, carrying the guide, enters the right atrium from the left atrium.

[0026] Furthermore, the direction of the first puncture of the double puncture structure is from the proximal end to the distal end, and the direction of the second puncture of the double puncture structure is from the distal end to the proximal end.

[0027] Furthermore, the first puncture of the double-puncture structure is from the right atrium through the secondary septum to the left atrium, and the second puncture of the double-puncture structure is from the left atrium through the primary septum to the right atrium.

[0028] Furthermore, the double-puncture structure penetrates both the tertiary and primary septa simultaneously during the first puncture.

[0029] Furthermore, the double-puncture structure simultaneously penetrates the primary septum / secondary septum during the second puncture.

[0030] Furthermore, the direction of the first puncture of the double puncture structure is opposite to the direction of the second puncture of the double puncture structure.

[0031] Furthermore, the repair system also includes an outer sheath, and the retrieval conduit and the capture rod are sleeved inside the outer sheath.

[0032] Furthermore, the repair system also includes an operating handle that controls the movement of the dual-puncture structure, the capture device, the repair component, and the stabilizing structure.

[0033] Furthermore, the guide includes a sharp part and a limiting step. The advantages of this design are: first, the sharp part helps the double puncture structure to puncture; second, the limiting step restricts the limiting unit to be placed at the far end of the double puncture structure; and third, the limiting step facilitates the capture ring's grasping.

[0034] Compared with the prior art, the advantages of the technical solution of this application include at least the following: 1. In existing technologies, when a puncture structure is used for puncture, problems arise due to the small thickness and high flexibility of the tissue being punctured, and because the puncture structure only provides puncture force in one direction and does not provide corresponding reverse support force. This makes it difficult for the puncture structure to pass through the tissue to be repaired normally, leading to puncture failure or unsatisfactory puncture positions. The technical solution of this application avoids these problems. This solution employs a repair system that facilitates puncture, including a double puncture structure, a grasping device, and a repair component. First, the repair component is at least partially fitted within the double puncture structure. During the repair process, the double puncture structure can pass back and forth through the tissue to be repaired. This is equivalent to driving the repair component to pass through the first and second tissues sequentially. Furthermore, because... The repair component is fitted within the double-puncture structure, preventing interference or damage to tissue during surgery. Furthermore, it's worth noting that the grasping device, positioned at the first puncture point of the double-puncture structure and abutting against the tissue, provides support for the second puncture (the second puncture site is thinner and more flexible). This balance of forces, with support and puncture force from both proximal and distal directions, allows the double-puncture structure to smoothly puncture the target location on the second tissue, ensuring accuracy and facilitating subsequent repair procedures. This design is highly practical and has significant potential for wider application.

[0035] 2. In the prior art, after the first puncture, the puncture structure is unable to support and penetrate the primary septum during the second puncture due to the lack of any support, easily leading to puncture failure or tearing of the primary septum causing secondary damage. The technical solution of this application avoids these problems. This solution employs a repair system that facilitates puncture, including a double-puncture structure, a grasping device, and repair components. After the first puncture by the double-puncture structure, the grasping device abuts against the primary septum or the primary and secondary septum at the side of the first puncture starting point, providing distal support for the double-puncture structure to puncture the primary septum. Furthermore, since the direction of the second puncture is proximal, the primary septum receives support from the double-puncture structure and the grasping device. The forces in both directions are firmly clamped during puncture, preventing significant shaking or vibration of the primary septum throughout the second puncture. The dual-puncture structure allows for easy puncture at the target location without tearing intracardiac tissue, improving surgical safety. Furthermore, the operation is simple and efficient, possessing significant clinical value. In addition, after providing support, the grasping device can also grasp the repair component. Under the action or pull of the grasping device, the locking unit of the repair component can move to connect or contact both the first and second puncture points. Subsequently, the locking unit is operated to pull or traction the secondary and primary septa together to complete the repair of the foramen ovale. In summary, the grasping device is ingeniously designed, multi-functional, and highly practical.

[0036] 3. According to a concept of this application, the repair component includes a locking unit and a connecting unit. The distal end of the connecting unit is connected to a guide. The locking unit and the connecting unit are pre-installed within a double-puncture structure. The guide is sharp and connected to the distal end of the double-puncture structure. The purpose of this design is that, since the locking unit is made of metal, its placement within the double-puncture structure not only avoids interference with the tissue during puncture but also facilitates the movement of the locking unit to the target position. The double-puncture structure provides a "movement track" for the locking unit, resulting in a high degree of fit and smooth operation. On the other hand, since the guide is designed to penetrate the tissue to be repaired before being captured by the capture device into the outer sheath, its sharp shape helps the double-puncture structure penetrate the tissue. Furthermore, the guide also includes a limiting step, which facilitates capture by the capture ring. In summary, the components fit tightly together, resulting in high operability.

[0037] 4. According to a concept of this application, the repair system also includes a stabilizing structure connected to the dual-puncture structure. The stabilizing structure includes a fixing member connected to the first puncture member. After the first puncture member completes the first puncture, tightening or operating the connecting member can fix the position of the first puncture member. This is beneficial for ensuring the puncture angle and puncture point position of the second puncture member when it is punctured, so that the second puncture member will not bend arbitrarily when it is punctured, thereby stably puncturing the tissue.

The repair component 3 is at least partially fitted within the double-puncture structure 1. During the repair process, the double-puncture structure 1 can puncture two tissues with gaps back and forth. The gripping device 2 is positioned at the first puncture starting point of the double-puncture structure 1 and abuts against the tissue, providing support for the tissue punctured by the double-puncture structure 1 in the second puncture. Furthermore, the double-puncture structure 1 delivers the repair component 3 to the target position during the puncture process, and the repair component 3 connects the two punctured tissues to reduce or eliminate gaps.

[0054] In this first embodiment, the repair system further includes a guide 5 connected to the distal end of the repair component 3, such as... Figure 2a As shown.

[0055] In this first embodiment, the double-puncture structure 1 includes a first puncture member 11 and a second puncture member 12; and the second puncture member 12 is sleeved inside the first puncture member 11, as shown below. Figure 2b As shown.

[0056] In this first embodiment, the distal end of the guide 5 is pointed. The guide 5 is pre-installed at the distal end of the double-puncture structure 1, such as... Figure 2c As shown.

[0057] In this first embodiment, the guide 5 includes a pointed portion 51 and a limiting step 52, such as Figure 2a As shown, the advantages of this design are: first, the sharp part 51 is conducive to assisting the double puncture structure 1 in puncturing; second, the limiting step 52 restricts the limiting unit to be placed at the far end of the double puncture structure 1; and third, the limiting step 52 is conducive to the capture circle 22 grasping.

[0058] In this first embodiment, when the dual-puncture structure 1 performs its first puncture, the first puncture member 11 pushes the guide member 5 to complete the puncture, as shown below. Figure 3b As shown; when the double-puncture structure 1 performs a second puncture, the first puncture member 11 or the second puncture member 12 pushes the guide member 5 to complete the puncture, as shown.

[0061] In this first embodiment, the repair system further includes a retrieval catheter 6. The dual-puncture structure 1 and the stabilizing structure 4 are pre-installed within the retrieval catheter 6. Furthermore, the distal end of the retrieval catheter 6 is pointed. To retrieve the dual-puncture structure 1, the retrieval catheter 6 passes through the tissue that was first punctured, such as... Figure 5a As shown.

[0062] In this first embodiment, the first puncture element 11 can only be retrieved after the retrieval catheter 6 has passed through the tissue punctured for the first time.

[0064] In this first embodiment, before the second puncture of the double-puncture structure 1, the proximal portion of the capture ring 22 abuts against the tissue; and, in the projection direction of the capture ring 22, the guide 5 is positioned within the capture ring 22, such as... Figure 1a As shown.

[0065] In this first embodiment, when the double puncture structure 1 performs a second puncture, the tissue subjected to the second puncture receives the puncture force provided by the double puncture structure 1 or the guide 5 and the support force provided by the capture ring 22. The puncture force is directed towards the proximal end, and the support force is directed towards the distal end, so that the tissue subjected to the second puncture is confined between the two and stably held in place, thus successfully achieving the second puncture.

[0067] The distal end of the capture circle 22 captures the guide member 5. During the process of pulling the capture rod 21 towards the proximal end, the connecting unit 32 sequentially passes through the first puncture point and the second puncture point, moving towards the proximal end. Figure 6a and 6b As shown; and, when the locking unit 31 is connected to or in contact with both the first puncture point and the second puncture point, as...

[0071] In this first embodiment, the distal end of the first puncture member 11 is J-shaped, and the distal end of the second puncture member 12 is U-shaped.

[0072] In one embodiment, under natural conditions, the length of the distal end of the second puncture member 12 is greater than the length of the first puncture member 11.

[0073] The exemplary operation process of the repair system in this embodiment is as follows: 1. The outer sheath 8 enters the right atrium via a femoral vein approach, and the retrieval catheter 6 is manipulated to abut against the secondary septum, such as... Figure 3a As shown, the first puncture member 11 is then manipulated to push against the guide member 5 through the secondary septum, completing the first puncture of the double puncture structure 1, as follows. Figure 3b and 3c As shown; 2. Operate the capturing device 2 to make the capturing ring 22 exit from the limiting tube 7 and return to its original state, such as... Figure 4a As shown, the proximal end of the capture ring 22 abuts against the primary hair septum, and the connecting member 42 is pulled to maintain the stability of the first piercing member 11, as... Figure 4b As shown, the second puncture member 12 then pushes against the guide member 5 through the hair septum, completing the second puncture of the double puncture structure 1, as follows. Figure 4c As shown; 3. Maneuver the retrieval catheter 6 through the puncture site of the first tissue, such as... Figure 5a As shown, the double-puncture structure 1 is then retrieved, and the stabilizing structure 4 is retrieved together with the double-puncture structure 1 into the retrieval catheter 6, as shown. Figure 5b and 5c As shown; 4. Operate the capturing device 2 to move it closer to the end, the guide 5 is captured into the capturing circle 22, and pull the capturing rod 21 to move it closer to the end, as shown. Figure 6a As shown, the guide 5 moves towards the proximal end as the capture circle 22 moves. During the pulling process, the connecting unit 32 passes through the first puncture point and the second puncture point in sequence, as... Figure 6b As shown; 5. Continue pulling the capture lever 21 towards the proximal end. When the locking unit 31 is connected to or in contact with both the first puncture point and the second puncture point, as... Figure 6c and 6d As shown, rotate the repair component 3 until the locking unit 31 separates from the repair component 3, as... Figure 6e and 6f As shown; 6. Retrieve the outer sheath tube 8; implantation complete.

It includes at least a double-puncture structure 1, a gripping device 2, and a repair component 3. The repair component 3 is at least partially fitted inside the double-puncture structure 1. During the repair process, the double-puncture structure 1 can puncture two tissues with gaps back and forth. The gripping device 2 is positioned on the first puncture starting point side of the double-puncture structure 1 and abuts against the tissue, providing support for the tissue punctured by the double-puncture structure 1 in the second puncture. Furthermore, during the puncture process, the double-puncture structure 1 delivers the repair component 3 to the target position. The repair component 3 connects the two punctured tissues to reduce or eliminate gaps.

[0076] In this second embodiment, the guide 5 is in the shape of a coil, a thread end, or a ball, such as... Figure 7a As shown.
