Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a heart intervention surgery implant-free suturing device. BACKGROUND

[0002] With the continuous development of cardiovascular disease diagnosis and treatment technology, heart intervention surgery has gradually replaced traditional open chest surgery and become the mainstream means for treating coronary heart disease, arrhythmia, heart structure defects and other diseases due to its small trauma, fast recovery and definite effect. In common heart intervention surgeries such as percutaneous coronary intervention and transcatheter aortic valve replacement, effective closure of postoperative vascular puncture wounds or intra-cardiac operation wounds is a key link to ensure surgical safety and reduce the risk of complications. The mainstream treatment method in clinical practice is to use implant closure devices such as vascular suture devices and occluders, which achieve closure by implanting metal anchors, suture anchors, polymer occlusive pads and other implants at the wound site.

[0003] However, implant-dependent closure devices have many inherent defects in clinical application. Metal implants may cause local tissue inflammatory reactions, thrombosis, and even serious complications such as vascular stenosis and perforation due to implant migration. Polymer implants have problems such as incomplete degradation and poor compatibility with body tissues. Although existing implant-free suturing devices avoid the risks of implants, most suturing devices complete valve puncture suturing through barbed needles, which have a low success rate of hooking artificial sutures, reducing the success rate of surgery and prolonging the operation time. SUMMARY

[0004] In view of the problems in the prior art, the purpose of the present application is to provide a heart intervention surgery implant-free suturing device.

[0005] To solve the above problems, the technical scheme adopted by the present application is as follows.

[0007] The adjusting assembly comprises a sliding groove formed in the fixed plate, a plurality of sliding seats are slidably connected in the sliding groove, one end of the sliding seat away from the puncture needle is rotatably connected with a rotating plate, a adjusting plate is rotatably connected in the sliding groove, and the adjusting plate is rotatably connected with the rotating plate, a threaded rod is rotatably connected in the sliding groove, and the threaded rod is threadedly connected with the sliding seat away from the adjusting plate;

[0008] The release assembly includes a top seat fixedly connected to a slide. A light rod is fixedly connected to one end of the top seat near the puncture needle. A second truncated cone is fixedly connected to one end of the light rod away from the top seat. A sleeve is fixedly connected to one end of the puncture needle near the slide. Two telescopic grooves are symmetrically opened inside the sleeve. A telescopic rod is slidably connected inside the telescopic grooves. A locking block is fixedly connected to one end of the telescopic rod near the second truncated cone, and the locking block is adapted to the second truncated cone.

[0009] Optionally, a sliding groove is provided inside the grip bar, and a pull plate and a push plate are slidably connected in the sliding groove. Two connecting plates are symmetrically installed at the end of the pull plate near the push plate, and an installation plate is fixedly connected to the end of the connecting plate near the push plate.

[0010] Optionally, an electric rod is fixedly connected to the mounting plate, and the output end of the electric rod is fixedly connected to the mounting plate.

[0011] Optionally, a snap-fit ​​groove is provided inside the cylinder, and a slide rod is slidably connected in the snap-fit ​​groove. A limit block is fixedly connected to one end of the slide rod located inside the cylinder.

[0012] Optionally, the puncture needle is provided with a slot, and the limiting block is adapted to the slot, and a frustum is slidably connected to the outer wall of the optical rod.

[0013] Optionally, two rotating seats are installed on the side of the push plate away from the pull plate, and the rotating seats are fixedly connected to the push plate, with clamps rotatably connected inside the rotating seats.

[0014] Optionally, an electric actuator is fixedly connected to the push plate, and a guide plate is fixedly connected to the output end of the electric actuator. Hinges are installed at both ends of the guide plate, and the hinges are rotatably connected to the guide plate. The end of the hinge away from the guide plate is rotatably connected to the clamp.

[0015] Optionally, a sleeve is slidably connected inside the grip, and the sleeve is fixedly connected to the pull plate. An adjustment groove is provided on the grip, and an adjustment knob is slidably connected inside the adjustment groove. The adjustment knob is fixedly connected to the arc-shaped end of the sleeve.

[0016] Optionally, an adjusting rod is slidably connected inside the sleeve, the adjusting rod is fixedly connected to the push plate, and the pull plate is slidably connected to the adjusting rod.

[0017] Optionally, a support plate is fixedly connected to the end of the grip rod away from the sliding groove, and an insertion rod is slidably connected to the support plate. The adjusting rod is evenly provided with multiple insertion holes, and the insertion rod is adapted to the insertion holes.

[0018] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0019] In the above solution, the problem of the inability to adjust the suture needle spacing in the existing device is solved by setting an adjustment component. This component drives the threaded rods in the two fixed plates to rotate, so that the slide in the groove can be adjusted at equal intervals, thereby adjusting the position of the puncture needle and the cylinder synchronously. The position of the puncture needle can be adjusted by pushing the adjustment knob, and the position of the clamp can be adjusted by pulling the adjustment rod, so as to avoid scratching the tissue around the wound during the movement of the gripping rod. By adjusting the suture needle spacing, the application range of the suturing device is effectively expanded.

[0020] The newly designed release mechanism addresses the issues of implant-induced inflammation and low success rate of needle suture snagging in existing devices. An electric actuator drives clamps to tighten the area requiring suturing. Simultaneously, a pressure sensor at the contact point between the clamps and the suture site, linked to the electric actuator, prevents damage to the suture site due to excessive clamping force. Driven by the electric actuator, the puncture needle passes through the suture site and inserts into the cylinder. The cylinder engages the puncture needle, causing it to press against a locking block within the sleeve, automatically disengaging it from the truncated cone. Finally, the puncture needle pulls the suture to complete the automatic suturing of the wound. This design avoids implant-induced inflammation and significantly improves suturing efficiency.

[0039] like Figures 1 to 9 As shown, this embodiment of the invention provides a non-implantable suture device for cardiac interventional surgery, including a handle 1, two fixing plates 18, a puncture needle 32 (located on one fixing plate 18), and a cylinder 21 (located on the other fixing plate 18). An adjustment component for adjusting the spacing of the puncture needles 32 is installed inside the fixing plate 18, and a release component for automatically releasing the puncture needle 32 is installed at the end of the puncture needle 32 near the fixing plate 18.

[0040] like Figure 6 and Figure 7As shown, the adjustment assembly includes a slide groove 19 formed in a fixed plate 18. Multiple slide seats 20 are slidably connected in the slide groove 19. A rotating plate 28 is rotatably connected to the end of each slide seat 20 away from the puncture needle 32. An adjustment plate 27 is rotatably connected in the slide groove 19, and the adjustment plate 27 is rotatably connected to the rotating plate 28. The rotating plate 28 is rotatably connected between two adjacent slide seats 20. A threaded rod 26 is rotatably mounted on the fixed plate 18. The threaded rod 26 passes through the slide groove 19. The threaded rod 26 includes a smooth rod with an external thread. The slide seat 20 located at the external thread is threadedly connected to the threaded rod 26. The remaining slide seats 20 are slidably mounted on the smooth rod.

[0041] like Figure 2 As shown, a sliding groove 7 is provided inside the grip 1. A pull plate 9 and a push plate 10 are slidably connected in the sliding groove 7. Two connecting plates 11 are symmetrically installed on the pull plate 9 near the push plate 10. A mounting plate 12 is fixedly connected to the end of the connecting plate 11 near the push plate 10. The two mounting plates 12 are respectively installed on the two connecting plates 11, and two fixing plates 18 are respectively installed on the two mounting plates 12. Specifically, as shown... Figure 6 As shown, one of the fixing plates 18 is fixedly installed on the mounting plate 12, and a cylinder 21 is installed on the slide 20 inside the fixing plate 18; as Figure 7 As shown, another fixing plate 18 is mounted on the mounting plate 12 via an electric actuator 29. A top seat 33 and a puncture needle 32 are mounted on a slide 20 inside the fixing plate 18, and a cylinder 21 is mounted on the fixing plate. When the electric actuator 29 is activated, it pushes the fixing plate 18 toward the other fixing plate 18 until the puncture needle 32 is inserted into the cylinder 21.

[0042] like Figure 6 As shown, a snap-fit ​​groove 22 is provided inside the cylinder 21, and a slide rod 23 is slidably connected inside the snap-fit ​​groove 22. One end of the slide rod 23 located inside the cylinder 21 is fixedly connected to a limit block 24. Figure 2 As shown, a sleeve 8 is slidably connected inside the grip 1, and the sleeve 8 is fixedly connected to the pull plate 9. An adjustment groove 3 is provided on the grip 1, and an adjustment knob 5 is slidably connected inside the adjustment groove 3. The adjustment knob 5 is fixedly connected to the arc-shaped end of the sleeve 8. An adjustment rod 2 is slidably connected inside the sleeve 8. The adjustment rod 2 is fixedly connected to the push plate 10, and the pull plate 9 is slidably connected to the adjustment rod 2. A support plate 4 is fixedly connected to the end of the grip 1 away from the sliding groove 7. An insertion rod 6 is slidably connected to the support plate 4. A spring is sleeved on the insertion rod 6. One end of the spring is connected to the support plate, and the other end is connected to the middle of the insertion rod 6. A plurality of insertion holes 39 are evenly provided on the adjustment rod 2, and the insertion rod 6 is adapted to the insertion holes 39.

[0043] To broaden the application range of the suturing device, this invention includes an adjustment component. This component drives the threaded rods 26 within the two fixed plates 18 to rotate, enabling the slide blocks 20 within the slide grooves 19 to be adjusted at equal intervals. This allows for synchronous adjustment of the positions of the puncture needle 32 and the cylinder 21. By pushing the adjustment knob 5 to adjust the position of the puncture needle 32 and pulling the adjustment rod 2 to adjust the position of the clamp 14, the device avoids scratching the tissue around the wound during the movement of the grip rod 1. By adjusting the spacing between the suture needles, the application range of the suturing device is effectively expanded.

[0044] Specifically, first, push the adjusting knob 5 to move the sleeve 8 and pull plate 9, causing the puncture needle 32 and cylinder 21 on the mounting plate 12 to retract into the sliding groove 7. Then, pull the adjusting rod 2 to retract the push plate 10 and clamp 14 into the sliding groove 7, preventing the gripping rod 1 from scratching the tissue around the wound during movement. Control the rotation of the motor matched with the threaded rod 26 according to the size of the wound, driving the slide seat 20 in the sliding groove 19 to slide. It is worth noting that only one slide seat 20 is threadedly connected to the threaded rod 26, while the other slide seats 20 are not threaded to the threaded rod. 26 Sliding contact, one slide 20 moves, causing the remaining slides 20 to move along the groove 19 opened on the fixed plate 18 under the pull of the rotating plate 28. The adjustment principle of the two fixed plates 18 is the same, both adjusting the slides 20 at equal distances by rotating the threaded rod 26. After the position of the suture needle is adjusted, the doctor holds the handle 1 and slowly pushes the prepared suture device along the sheath retained after the cardiac intervention surgery. The accuracy of the position of the puncture needle 32 and the clamp 14 is ensured by the matching DSA multi-angle projection.

[0045] Secondly, once the suturing device reaches the designated position, pull out the insertion rod 6 along the insertion hole 39 on the adjusting rod 2, slowly push the adjusting rod 2 so that the push plate 10 extends along the sliding groove 7, and when the clamp 14 on the push plate 10 moves to the wound, release the insertion rod 6 so that the insertion rod 6 is inserted into the insertion hole 39 under the push of the spring sleeve on it, thus limiting the position of the adjusting rod 2. Push the adjusting knob 5 along the adjusting groove 3 so that the sleeve 8 and the pull plate 9 extend along the sliding groove 7 and move to the position that matches the clamp 14, thus preparing for suturing at the wound.

[0046] like Figures 7 to 9As shown, the release assembly includes a top seat 33, which is located on a fixed plate 18 on which an electric actuator 29 is mounted. Specifically, the top seat 33 is fixedly connected to the slide 20. A smooth rod 34 is fixedly connected to one end of the top seat 33 near the puncture needle 32, and a second frustum 36 is fixedly connected to the other end of the smooth rod 34 away from the top seat 33. A sleeve 30 is fixedly connected to one end of the puncture needle 32 near the slide 20. Two telescopic grooves 37 are symmetrically formed inside the sleeve 30. A telescopic rod 38 is slidably connected inside the telescopic grooves 37. A locking block 25 is fixedly connected to one end of the telescopic rod 38 near the second frustum 36, and the locking block 25 is adapted to the second frustum 36. A spring is sleeved on the telescopic rod 38, with one end of the spring connected to the inner wall of the telescopic groove 37 and the other end connected to the locking block. An electric rod 29 is fixedly connected to the mounting plate 12. The output end of the electric rod 29 is fixedly connected to the fixing plate 18. A slot 31 is provided on the puncture needle 32, and the limiting block 24 is adapted to the slot 31. A frustum 35 is slidably connected to the outer wall of the optical rod 34.

[0047] like Figure 5 As shown, two rotating seats 13 are installed on the side of the push plate 10 away from the pull plate 9, and the rotating seats 13 are fixedly connected to the push plate 10. A clamp 14 is rotatably connected inside the rotating seat 13. An electric push rod 15 is fixedly connected to the push plate 10. A guide plate 17 is fixedly connected to the output end of the electric push rod 15. A hinge plate 16 is installed at both ends of the guide plate 17, and the hinge plate 16 is rotatably connected to the guide plate 17. The end of the hinge plate 16 away from the guide plate 17 is rotatably connected to the clamp 14.

[0048] To improve suturing efficiency, this invention incorporates a release mechanism. An electric actuator 15 drives a clamp 14 to clamp the area to be sutured. Simultaneously, a pressure sensor is installed at the contact end between the clamp 14 and the suture site. This sensor, linked to the electric actuator 15, prevents damage to the suture site due to excessive clamping force. Driven by an electric rod 29, the puncture needle 32 passes through the suture site and inserts into the cylinder 21. The cylinder 21 engages with the puncture needle 32, causing it to press against the locking block 25 within the sleeve 30, automatically disengaging it from the frustum 36. Finally, the puncture needle 32 pulls the suture to complete the automatic suturing of the wound. This design avoids inflammation caused by the implant and significantly improves suturing efficiency.

[0049] Specifically, firstly, the electric actuator 15 pulls the guide plate 17, causing the guide plate 17 to pull the clamp 14 to clamp the wound. Simultaneously, a pressure sensor is installed at the contact end of the clamp 14 with the wound, and this sensor is linked to the electric actuator 15. The electric actuator 15 automatically adjusts its extension and retraction based on the monitoring data from the pressure sensor to avoid damage to the suture site due to excessive clamping force. After the wound is clamped, the position of the fine-tuning sleeve 8 is adjusted, thereby adjusting the position of the puncture needle 32. The electric rod 29 pushes the fixing plate 18 to move, bringing the puncture needle 32 and the cylinder 21 closer together. It is worth noting... It is worth noting that the mounting plate 12 moves away from the clamp 14 under the push of the pull plate 9 and the connecting plate 11. The movement of the puncture needle 32 and the cylinder 21 will not contact the clamp 14. After the previous synchronous adjustment, the positions of the puncture needle 32 and the cylinder 21 are set accordingly. When the puncture needle 32 passes through the wound clamped by the clamp 14, the puncture needle 32 is inserted into the cylinder 21. The limiting block 24 in the cylinder 21 engages with the slot 31 opened on the puncture needle 32. At the same time, the needle tip of the puncture needle 32 is inserted into the conical sleeve set in the cylinder 21 to fix the position of the puncture needle 32.

[0050] Secondly, as the electric rod 29 extends further, the locking block 25 inside the sleeve 30 pushes the first truncated cone 35 to slide along the smooth rod 34, making the first truncated cone 35 fit tightly against the top seat 33. When the locking block 25 passes the end of the first truncated cone 35 away from the top seat 33, the locking block 25 slides along the conical end of the first truncated cone 35, and at this time the mounting plate 12 is not in contact with the wound suture. At this time, the electric rod 29 is controlled to retract, and the locking block 25, pushed by the spring force of the telescopic rod 38, clamps the first truncated cone 35 and moves it along the smooth rod 34, making the first truncated cone 35 fit against the second truncated cone 36. Under the pull of the electric rod 29, the locking block 25 and the telescopic rod 38 move along... As the telescopic groove 37 retracts, after the locking block 25 passes the contact end of the first truncated cone 35 and the second truncated cone 36, the locking block 25 and the telescopic rod 38 spring back. At this time, the puncture needle 32 passes through the suture under the pull of the cylinder 21. At the same time, the sleeve 30 is equipped with suture thread, and the two ends of the suture thread are fixedly connected to the sleeve 30 and the second truncated cone 36 respectively. At this time, there will be suture thread at both ends of the wound. The suture thread can be knotted to complete the suturing of the wound. The above-mentioned components have been thoroughly disinfected and sterilized before use, and the suture thread is also a bioabsorbable suture thread. After the suturing is completed, the clamp 14 and the puncture needle 32 are returned to the sliding groove 7 according to the above method, and the suturing device is removed from the wound.

[0051] The working principle of this invention is as follows: First, push the adjusting knob 5 to move the sheath 8 and the pull plate 9, causing the puncture needle 32 and the cylinder 21 on the mounting plate 12 to retract into the sliding groove 7. Pull the adjusting rod 2 to retract the push plate 10 and the clamp 14 into the sliding groove 7, driving the slide seat 20 in the sliding groove 19 to slide. After the suture needle position is adjusted, slowly push the prepared suture device along the sheath retained after the cardiac intervention surgery. Use the matching DSA multi-angle projection to ensure the accuracy of the position of the puncture needle 32 and the clamp 14. When the suture device reaches the designated position, pull out the insertion rod 6 along the insertion hole 39 on the adjusting rod 2. Slowly push the adjusting rod 2 to extend the push plate 10 along the sliding groove 7. When the clamp 14 on the push plate 10 moves to the wound, release the insertion rod 6, allowing the spring on the insertion rod 6 to push down. Insert the insertion hole 39 to limit the position of the adjusting rod 2. Push the adjusting knob 5 along the adjusting groove 3 to make the sleeve 8 and the pull plate 9 extend along the sliding groove 7 and move to the matching position with the clamp 14. The electric push rod 15 drives the clamp 14 to clamp the part to be sutured. At the same time, the contact end of the clamp 14 with the suture is equipped with a pressure sensor. This sensor is linked with the electric push rod 15 to avoid damage to the suture due to excessive clamping force. Under the push of the electric rod 29, the puncture needle 32 passes through the suture and is inserted into the cylinder 21. The cylinder 21 forms a locking contact with the puncture needle 32, causing the puncture needle 32 to squeeze the locking block 25 in the sleeve 30, so that it automatically releases the locking contact with the second truncated cone 36. At this time, the puncture needle 32 passes through the suture under the pull of the cylinder 21. At this time, there will be sutures at both ends of the wound. Tie the sutures to complete the suturing of the wound.
