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.

[0046] As Figures 7 to 9As shown, the release assembly comprises a top seat 33 located on the fixed plate 18 on which the electric push rod 29 is mounted, specifically the top seat 33 fixedly connected to the sliding seat 20, a light rod 34 fixedly connected to one end of the top seat 33 close to the puncture needle 32, and a circular table two 36 fixedly connected to the other end of the light rod 34 away from the top seat 33. The puncture needle 32 is fixedly connected to a sleeve 30 close to the sliding seat 20, two expansion slots 37 are symmetrically formed in the sleeve 30, an expansion rod 38 is slidably connected in the expansion slot 37, a clamping block 25 is fixedly connected to one end of the expansion rod 38 close to the circular table two 36, the clamping block 25 is matched with the circular table two 36, a spring is sleeved on the expansion rod 38, one end of the spring is connected to the inner wall of the expansion slot 37, and the other end of the spring is connected to the clamping block. The mounting plate 12 is fixedly connected with the electric rod 29, the output end of the electric rod 29 is fixedly connected with the fixed plate 18, the puncture needle 32 is provided with a clamping groove 31, the limiting block 24 is matched with the clamping groove 31, and the outer wall of the light rod 34 is slidably connected with a circular table one 35.

[0047] As shown in the figure, Figure 5 The push plate 10 is provided with two rotating seats 13 away from the pull plate 9, and the rotating seats 13 are fixedly connected with the push plate 10, the rotating seats 13 are rotatably connected with the clamps 14, the push plate 10 is fixedly connected with the electric push rod 15, the output end of the electric push rod 15 is fixedly connected with the guide plate 17, the both ends of the guide plate 17 are provided with the hinged plates 16, the hinged plates 16 are rotatably connected with the guide plate 17, and the one end of the hinged plate 16 away from the guide plate 17 is rotatably connected with the clamp 14.

[0048] In order to improve the stitching efficiency, the release assembly is arranged, the clamp 14 is driven by the electric push rod 15 to clamp the part to be stitched, and the contact end of the clamp 14 with the stitching part is provided with a pressure sensor, the sensor is linked with the electric push rod 15, so that damage to the stitching part caused by excessive clamping force can be avoided; under the pushing of the electric rod 29, the puncture needle 32 penetrates through the stitching part and is inserted into the cylinder 21, the cylinder 21 forms clamping with the puncture needle 32, the puncture needle 32 is pressed to extrude the clamping block 25 in the sleeve 30, so that the clamping block 25 is automatically disengaged from the circular table two 36, and finally the puncture needle 32 pulls the suture to complete the automatic suture of the wound. This design not only avoids inflammation caused by the implant, but also significantly improves the stitching efficiency.

[0049] Specifically, first, the electric push rod 15 pulls the guide plate 17, so that the guide plate 17 pulls the clamp 14 to clamp the wound, and the clamp 14 is provided with a pressure sensor at the contact end of the wound, and the sensor is linked with the electric push rod 15. The electric push rod 15 automatically adjusts its extension according to the monitoring data of the pressure sensor to avoid damage to the suture site due to excessive clamping force. After the wound is clamped, the position of the micro-adjusting sleeve 8 is adjusted to adjust the position of the puncture needle 32. The puncture needle 32 and the cylinder 21 are moved close to each other by the electric rod 29 pushing the fixed plate 18 to move. It is worth noting that the mounting plate 12 is moved away from the clamp 14 under the pushing 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 correspondingly arranged. When the puncture needle 32 passes through the wound clamped by the clamp 14, the puncture needle 32 is inserted into the cylinder 21, and the limiting block 24 in the cylinder 21 is clamped with the clamping groove 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 arranged in the cylinder 21 to fix the position of the puncture needle 32.

[0050] Secondly, with the further extension of the electric rod 29, the clamping block 25 in the sleeve 30 pushes the circular table one 35 to slide along the light rod 34, so that the circular table one 35 is tightly attached to the top seat 33. When the clamping block 25 passes the end of the circular table one 35 away from the top seat 33, the clamping block 25 slides along the conical end of the circular table one 35, and at this time the mounting plate 12 does not contact the suture site of the wound. At this time, the electric rod 29 is controlled to retract, and the clamping block 25 is pushed by the spring force of the spring arranged on the telescopic rod 38, so that the clamping block 25 clamps the circular table one 35 to move along the light rod 34, so that the circular table one 35 is attached to the circular table two 36. Under the pulling of the electric rod 29, the clamping block 25 and the telescopic rod 38 are retracted along the telescopic groove 37. When the clamping block 25 passes the contact end of the circular table one 35 and the circular table two 36, the clamping block 25 and the telescopic rod 38 rebound. At this time, the puncture needle 32 is pulled through the suture site under the pulling of the cylinder 21. The sleeve 30 is provided with a suture line, and the two ends of the suture line are fixedly connected with the sleeve 30 and the circular table two 36. At this time, the two ends of the wound will have a suture line, and the suture line can be knotted to complete the suture of the wound. The above components have been fully disinfected and sterilized before use. The suture line is a bioabsorbable suture line. After the suture is completed, the clamp 14 and the puncture needle 32 are retracted into the sliding groove 7 according to the above method, and the suture device is removed from the wound.
