Description

Technical Field

[0001] This invention belongs to the field of occlusion device technology, specifically relating to a femoral artery puncture site occlusion system. Background Technology

[0002] Femoral artery puncture is an interventional medical procedure in which a physician inserts a specialized needle into the femoral artery in the groin area (inner thigh) to establish arterial access. This technique is widely used in procedures such as coronary angiography and stent implantation, peripheral artery embolization, and aortic dissection stent placement. Post-procedure hemostasis at the puncture site is a crucial aspect of interventional procedures; improper handling can easily lead to complications such as hematoma, infection, and pseudoaneurysm, which can even be life-threatening in severe cases.

[0003] Currently, commonly used hemostasis methods in clinical practice mainly include manual compression, mechanical compression, suture closure, and collagen sponge-assisted hemostasis, but all of these methods have certain limitations: Manual compression relies on the operator's experience. Uneven pressure control may lead to incomplete hemostasis or vascular damage. It also requires continuous pressure for 15 to 20 minutes, which not only increases the workload of medical staff, but also requires patients to maintain a fixed position for a long time, which may cause discomfort such as lower back pain and limb numbness.

[0004] Mechanical compression therapy often lacks precise pressure adjustment; excessive pressure may cause skin damage or lower limb ischemia, while insufficient pressure can easily lead to bleeding. Furthermore, this method further restricts limb movement, prolongs bed rest, and affects postoperative recovery. Some patients may also experience allergic reactions to the device materials, or experience localized pain and swelling.

[0005] Suture closure requires a high level of skill from the operator, who must accurately suture the vessel wall and skin tissue at the puncture site. Inexperienced operators are prone to misaligning the sutures or failing to tie them securely, which can affect the hemostasis effect. In addition, suturing the skin tissue near the puncture site can further damage the skin, making the puncture site difficult to heal and easily leaving suture scars on the patient.

[0006] Collagen sponges are mainly suitable for small to medium diameter puncture sites (generally ≤6F). Their hemostatic effect is limited in cases of large diameter punctures or severe damage to the blood vessel wall. In addition, the sponge may be dispersed when blood flow is fast, resulting in hemostasis failure or delayed bleeding.

[0007] In summary, existing hemostasis methods still have significant shortcomings in terms of ease of operation, applicability, and safety.

[0008] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0009] The purpose of this invention is to provide a femoral artery puncture site occlusion system to solve the technical problems of existing hemostasis methods, such as complex operation, poor hemostasis reliability, and the tendency to cause additional trauma and pain to patients.

[0010] To achieve the above objectives, the femoral artery puncture site occlusion system of the present invention provides the following technical solution: A femoral artery puncture site occlusion system includes: An occlusion assembly has an occlusion disc and an anchoring component disposed opposite to each other, and a connecting component for connecting the occlusion disc and the anchoring component. The occlusion disc has a radially contracting rod-shaped form and a radially expanding disc-shaped form, and is used to extend into the blood vessel from the puncture site to block the puncture site on the blood vessel. The connecting component has an axially disposed receiving cavity inside, and the anchoring component is housed in the receiving cavity and extends out from the receiving cavity to anchor into the skin tissue near the puncture site when needed. A delivery assembly for receiving and delivering the occlusion assembly to the puncture site to jointly seal the puncture site in the blood vessel and skin tissue.

[0011] As a further optimized technical solution, the sealing disc has multiple support rods spaced apart along the circumference. One end of the support rod is fixedly connected to the connecting component, and the other end is used to rotate axially toward or away from the connecting component to realize the contraction and expansion of the sealing disc. A sealing membrane is provided on one side of the support rod.

[0012] As a further optimized technical solution, the anchoring component includes a limiting block, which is slidably disposed in the receiving cavity. The limiting block is provided with a plurality of anchoring spikes spaced circumferentially, and the anchoring spikes are used to extend out of the receiving cavity when the limiting block slides toward the sealing disc.

[0013] As a further optimized technical solution, the conveying assembly includes a push rod and a storage sleeve. The storage sleeve is fitted on the outside of the sealing assembly, and one end of the push rod extends into the receiving cavity of the connecting component to drive the anchoring component to extend out of the receiving cavity.

[0014] As a further optimized technical solution, the inner wall of the receiving cavity is provided with an internal thread, and one end of the push rod is provided with an external thread that matches the internal thread.

[0015] As a further optimized technical solution, the radial dimension of the anchoring spike gradually decreases from the end near the limiting block to the end away from the limiting block.

[0016] As a further optimized technical solution, the end of the anchoring spike away from the limiting block bends and extends in the direction close to the sealing disc.

[0017] As a further optimized technical solution, at least one axially extending guide protrusion is provided on the circumferential outer side of the limiting block, and a guide groove is provided on the inner wall of the receiving cavity at the corresponding position of the guide protrusion to cooperate with the guide protrusion. The limiting block achieves sliding cooperation with the receiving cavity through the cooperation of the guide protrusion and the guide groove.

[0018] As a further optimized technical solution, an operating handle is provided at the end of the push rod away from the connecting component.

[0019] As a further optimized technical solution, the outer side of the connecting component is covered with a sealing layer that can automatically expand after absorbing liquid, which is used to seal the puncture site.

[0020] Beneficial effects: First, this invention enables precise delivery and release of the occlusion component via a delivery assembly. The occlusion disc can retract into a rod-like shape, facilitating insertion into the blood vessel through the puncture site. After unfolding, it quickly occludes the vascular puncture site. The anchoring component is anchored by a push rod. The occlusion operation is completed after the occlusion disc unfolds and the anchoring component extends, eliminating the need for complex operations, reducing operational difficulty, improving surgical efficiency, and reducing reliance on the operator's experience. Second, this invention achieves dual and simultaneous occlusion of the vascular puncture path by sealing the vascular puncture site on the inner wall of the blood vessel with the occlusion disc and simultaneously anchoring it within the skin tissue through the anchoring component. This effectively prevents blood from seeping from the vascular rupture into the interstitial space to form a hematoma, resulting in a more stable and reliable hemostasis effect. Finally, the entire system is implanted via a minimally invasive method, and the anchoring component is anchored within the skin tissue near the puncture site, eliminating the need for sutures on the skin surface. This avoids additional trauma and scarring caused by sutures, greatly reducing patient pain and facilitating postoperative recovery.

[0021] Furthermore, the end of the anchoring needle bends towards the occlusion disc, forming a barb structure. This structure allows the anchoring needle to resist pulling forces from the proximal end (i.e., from the outside) after implantation, thus firmly locking the entire occlusion component in the preset position. This effectively prevents the component from falling off or shifting due to postoperative patient activity, ensuring long-term stability of the occlusion effect. In addition, this structure causes the tissue near the puncture site on the skin to tighten towards the puncture site, thereby facilitating healing of the puncture site. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] The shapes and sizes of the components in the accompanying drawings do not reflect the actual proportions of the product; they are only intended to illustrate the content of the invention.

[0028] This invention provides a femoral artery puncture site occlusion system, comprising an occlusion component 100 and a delivery component 200. The occlusion component 100 has an occlusion disc 110, an anchoring component 120, and a connecting component 130 connecting the two, all disposed opposite each other. The occlusion disc 110 can switch between a radially contracting rod-like shape and a radially expanding disc-like shape, used to occlude the puncture site on the blood vessel 300 after insertion. The connecting component 130 has a receiving cavity 131 inside, in which the anchoring component 120 is housed, and extends and anchors into the skin tissue 400 when fixation is required. The delivery component 200 is used to receive and deliver the occlusion component 100 to the puncture site. The connecting component 130 is covered with a liquid-swellable sealing layer 140. The support rod 111 of the occlusion disc 110 is made of a memory effect polymer material. The anchoring punctures 122 are circumferentially spaced and curved at their distal ends. The push rod 210 and the receiving cavity 131 are precisely driven through a threaded engagement. This invention achieves simultaneous, dual mechanical occlusion of the vascular puncture site and the tissue puncture channel through an occlusion system. It is easy to operate, has a reliable hemostatic effect, is minimally invasive, and effectively avoids complications such as hematoma and infection, significantly improving the safety and efficiency of hemostasis after femoral artery puncture.

[0029] Example 1 like Figure 1 As shown, the femoral artery puncture site occlusion system includes an occlusion component 100 and a delivery component 200.

[0030] like Figure 2 , Figure 3 , Figure 4 As shown, the occlusion assembly 100 includes an occlusion disc 110, an anchoring component 120, and a connecting component 130. The connecting component 130 is a hollow tubular structure, closed at the distal end and open at the proximal end, thereby forming an axially extending receiving cavity 131 within its internal space. The occlusion disc 110 is located at the distal end of the connecting component 130. The anchoring component 120 is normally housed within the receiving cavity 131 of the connecting component 130, and extends from the receiving cavity 131 to anchor into the skin tissue 400 near the puncture site when occlusion is required, and is arranged opposite to the occlusion disc 110.

[0031] The sealing disc 110 consists of multiple support rods 111 spaced circumferentially and a sealing membrane 112 covering one side of the support rods 111. One end of each support rod 111 is fixedly connected to a connecting component 130, and the other end is used to rotate axially toward or away from the connecting component 130 to achieve the contraction and expansion of the sealing disc 110. The preferred material for the support rods 111 is an absorbable polymer material with shape memory effect (such as a shape-memory polymer), for example, one or a combination of polylactic acid (PLA), polylactic acid-glycolic acid copolymer (PLGA), polycaprolactone (PCL), polytrimethylene carbonate (PTMC), and polyhydroxyalkanoate (PHA). These materials can automatically recover from a compressed rod-shaped form to a memorized disc-shaped form under body temperature (phase transition temperature) stimulation. This characteristic provides the driving force for the expansion of the sealing disc, making the expansion process gentler, more reliable, and with uniform force, thus improving safety during use. Simultaneously, after completing its occlusion mission (typically several weeks to months), the support rod 111 can be degraded into smaller molecules by hydrolytic enzymes in the body and absorbed by the body, ultimately eliminating the need for permanent retention. Furthermore, these materials exhibit good biocompatibility and adjustable degradation cycles. For example, the degradation rate of PLGA can be precisely controlled by the ratio of its monomers LA and GA to meet the needs of different healing cycles. The occlusion membrane 112 can be fixed to the side of the support rod 111 facing the vessel wall via suturing, bonding, or heat pressing. When the occlusion disc 110 is deployed within the vessel 300, the occlusion membrane 112 is tightly pressed against the inner wall of the vessel 300, physically blocking blood flow. The occlusion membrane 112 is also made of absorbable material, and its designed degradation cycle matches that of the support rod 111, typically being slightly shorter or equal to the degradation time of the support rod 111. This ensures that the occlusion membrane 112 and the support rod 111 continuously provide mechanical support until the endothelial cells at the vascular puncture site are fully healed and repaired. Once they have completed their mission, they will be absorbed by the body gradually and in synergy, eventually causing the entire occlusion disc 110 to disappear completely from the body without leaving any permanent implant.

[0032] The anchoring component 120 includes a limiting block 121 slidably disposed within a receiving cavity 131, and a plurality of anchoring spikes 122 circumferentially spaced on the limiting block 121. To facilitate the extension of the anchoring spikes 122 from the receiving cavity 131, a plurality of circumferentially spaced through holes 132 are provided on the side wall of the receiving cavity 131, each through hole 132 corresponding to one of the anchoring spikes 122. The anchoring spikes 122 are also made of an absorbable polymer material with shape memory effect, such as... Figure 3 As shown, when the anchoring component 120 is housed in the receiving cavity 131, the anchoring spike 122 is pre-shaped so that its tail end extends into the through hole 132, thereby facilitating the smooth passage of the anchoring spike 122 through the connecting component 130 and anchoring into the skin tissue 400 when the limiting block 121 is pushed.

[0033] Furthermore, the radial dimension of the anchoring needle 122 gradually decreases from the end near the limiting block 121 towards the distance, forming a sharp end to facilitate insertion into the skin tissue 400. Preferably, the end of the anchoring needle 122 bends and extends towards the sealing disc 110 (i.e., distal end), forming a barb structure. This structure allows the anchoring needle 122 to resist pulling forces from the proximal end (i.e., external direction) after implantation, thereby firmly locking the entire sealing component 100 in the preset position, effectively preventing the sealing component 100 from falling off or shifting due to postoperative patient activity, and ensuring long-term stability of the sealing effect. On the other hand, this structure causes the tissue near the puncture site on the skin tissue 400 to tighten towards the puncture site, thus making the puncture site easier to heal.

[0034] The delivery assembly 200 includes a push rod 210, a storage sleeve 220, and an operating handle 230. The storage sleeve 220 is a cylindrical structure with its proximal opening adapted to the outer diameter of the push rod 210. The proximal end is slidably disposed at one end of the push rod 210 for storing the sealing assembly 100. The distal end of the push rod 210 can extend into the receiving cavity 131 of the connecting component 130 and contact or connect with the limiting block 121 to push the anchoring component 120 to move axially. In this embodiment, in order to achieve precise linear control of the limiting block 121 sliding axially along the receiving cavity 131, the inner sidewall of the receiving cavity 131 is provided with an internal thread, and the distal end of the push rod 210 is provided with a matching external thread. By rotating the push rod 210, the limiting block 121 and the anchoring spike 122 can be precisely driven to move within the receiving cavity 131. The operating handle 230 is disposed at the proximal end of the push rod 210 for easy gripping and operation by the doctor.

[0035] Furthermore, a sealing layer 140 is also provided on the outside of the connecting component 130. This sealing layer 140 is made of a material that can automatically expand after absorbing liquids (such as blood or tissue fluid), such as gelatin sponge, collagen, or a superabsorbent polymer. When the sealing assembly 100 is in place, the sealing layer 140 absorbs liquid and expands, which can further fill and seal the gap between the skin tissue 400 and the connecting component 130.

[0036] Furthermore, such as Figure 3 , Figure 5As shown, in order to achieve stable and controllable threaded transmission between the push rod 210 and the connecting component 130, and to minimize the interference of the internal thread of the receiving cavity 131 on the sliding of the limiting block 121, at least two axially extending guide protrusions 123 are symmetrically arranged on the outer circumferential side of the limiting block 121. Simultaneously, guide grooves 133 that mate with the guide protrusions 123 are provided at corresponding positions on the inner wall of the receiving cavity 131. The guide protrusions 123 can slide freely within the guide grooves 133. Thus, when the push rod 210 rotates, the radial force it generates is mainly borne by the guide groove structure, thereby preventing the limiting block 121 from rotating with the thread, avoiding possible jamming, jumping, or skewing of the limiting block 121 due to thread friction, and ensuring that all anchoring spikes 122 extend synchronously and smoothly, with uniform anchoring force.

[0037] like Figure 6 , Figure 7 As shown, the usage process of this sealing system is as follows: First, the occlusion component 100, which is in a contracted state, is completely housed within the storage sleeve 220 of the delivery component 200. After the femoral artery puncture procedure is completed, the delivery component 200 containing the occlusion component 100 is delivered along the puncture site to the target position, allowing the occlusion disc 110 to pass through the puncture site on the blood vessel 300 and enter the blood vessel lumen.

[0038] Then, the retractable sleeve 220 is retracted to release the constraint on the occlusion disc 110. Under the action of its own memory effect, the support rod 111 unfolds outward, causing the occlusion membrane 112 to form a disc-shaped structure, which is tightly attached to the inner wall of the blood vessel 300, thereby sealing the puncture site on the blood vessel 300.

[0039] Rotating the operating handle 230 drives the push rod 210 to advance distally. The push rod 210 drives the limiting block 121 to slide axially distally within the receiving cavity 131 via a threaded engagement. The anchoring puncture 122 extends out of the connecting component 130 through the through hole 132 and pierces into the skin tissue 400 surrounding the puncture site, thus fixing the sealing component 100. In this embodiment, the specific anchoring method of the anchoring component 120 into the skin tissue 400 is as follows: Figure 7As shown, the anchoring component 120 is located in the subcutaneous tissue on one side of the puncture site of the blood vessel 300. By placing the anchoring point subcutaneously, sutures or any anchoring traces are avoided on the surface of the skin tissue 400. With only a tiny puncture point on the skin surface, it can heal quickly and naturally after instrument removal, greatly reducing the risk of infection and achieving a truly scarless effect, significantly improving the patient's postoperative experience and satisfaction. Furthermore, the subcutaneous tissue has a certain degree of toughness and thickness, providing a solid and reliable anchoring foundation for the anchoring needle 122. Simultaneously, this internal anchoring, in conjunction with the occlusion disc 110 within the blood vessel, forms a sandwich-type fixation structure that runs through the puncture channel, resulting in a more stable fixation effect and effectively resisting the risk of displacement caused by blood flow impact and patient movement.

[0040] At this point, the occlusion disc 110 is sealed within the blood vessel, the anchoring needle 122 is anchored within the tissue, and the connecting component 130 is located within the puncture channel. The sealing layer 140 expands after absorbing fluid, enhancing the seal.

[0041] Finally, the delivery assembly 200 is separated from the occlusion assembly 100, and the entire delivery assembly 200 is withdrawn from the puncture passage, completing the entire occlusion process. After occlusion, if the proximal end of the connecting component 130 protrudes too far from the skin, it can be cut to be flush with the outer surface of the skin tissue 400.

[0042] In summary, the femoral artery puncture site occlusion system provided by this invention achieves rapid, accurate, and reliable occlusion of the puncture site through the synergistic effect of the occlusion disc, anchoring component, sealing layer, and delivery component of the occlusion assembly. It is easy to operate and widely applicable, effectively reducing the risk of complications and improving the patient's postoperative recovery experience.

[0043] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are within the protection scope of the present invention.
