Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a foldable cardiac ear clip structure. Background Technology

[0002] Atrial fibrillation (AF) is the most common type of cardiac arrhythmia, characterized by irregular heartbeats. Non-valvular AF is a prevalent type of AF. The incidence of AF in the general population is 0.5% to 1.5%. The left atrial appendage is an accessory structure of the left atrium of the heart, appearing as a long, narrow, and curved tube with a narrow, pointed apex. It contains abundant pectinate muscles and trabeculae. In patients with AF, the entrance to the left atrial appendage is significantly widened, and the appendage loses its effective, regular contraction. The movement of the appendage walls makes it difficult to induce sufficient emptying of the left atrial appendage, leading to blood pooling and increasing the risk of thrombosis. In non-valvular AF, more than 90% of thrombus formation is related to the left atrial appendage. Currently, the main approach to preventing stroke in patients with AF is cardiac surgery or minimally invasive surgery to ligate the atrial appendage, which is a widely used treatment method. This ligation of the atrial appendage uses atrial appendage clips, but there are certain technical aspects of these clips that require improvement.

[0003] like Figure 1 Currently, there is a foldable atrial appendage clip structure on the market that uses a connecting tube as a clamping arm. The connecting tube is connected by a spring to provide clamping force. Both ends of the connecting tube have elastic rings. When performing minimally invasive left atrial appendage clipping surgery under thoracoscopic guidance, surgical forceps are needed to pull the atrial appendage out from the gap of the clamping arm before the atrial appendage can be clipped. This is inconvenient to operate, requires higher skill from the doctor, and increases the surgical risk.

[0004] like Figure 2 The prior art discloses a foldable atrial appendage clip structure, with patent application number 201910023097.0 and patent name "Heart Tissue Closure Device". One side provides elasticity and the other side can be opened. This structure is better than the atrial appendage clip and facilitates the operation of doctors in the thoracoscopic surgery environment. It can clamp the atrial appendage more easily. However, the clamping force on both sides of this structure is uneven, and there is a risk that the atrial appendage will fall off from the open side, which may lead to other more serious problems.

[0005] To address the above technical issues, there is an urgent need for a cardiac auricle clamp that is both easy for doctors to operate and provides uniform clamping force to ensure surgical safety. Summary of the Invention

[0006] This invention addresses the problems of existing technologies by providing a foldable atrial appendage clip structure. The structure is novel and ingeniously designed. The first and second clamping components are foldable and deformable, with a wide and virtually unrestricted folding angle range. This invention facilitates clamping the atrial appendage, making it easier for doctors to operate and reducing surgical time. Furthermore, the elasticity of the elastic connectors ensures that the atrial appendage remains clamped after being closed. Because elastic connectors are provided at both ends, the clamping force between the first and second clamping components is uniform and balanced, effectively preventing the atrial appendage clip from falling off and ensuring surgical safety and reliability.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] The present invention provides a foldable aortic clip structure, which includes a first clamping component and a second clamping component arranged in parallel; an elastic connector is connected between one end of the first clamping component and one end of the second clamping component, and between the other end of the first clamping component and the other end of the second clamping component, the elastic connector providing clamping force for the first clamping component and the second clamping component; both the first clamping component and the second clamping component are foldable and deformable structures.

[0009] The first clamping assembly includes at least two first clamping arms connected in sequence, with a first folding component disposed between adjacent two first clamping arms; the second clamping assembly includes at least two second clamping arms connected in sequence, with a second folding component disposed between adjacent two second clamping arms.

[0010] Preferably, both the first folding component and the second folding component are either elastic components or soft components.

[0011] Preferably, both the first folding component and the second folding component are one of a hinge, a folding rod, or a hinge.

[0012] Preferably, the first folding component is one of an elastic component or a flexible component, and the second folding component is one of a hinge, a folding rod, or a hinge.

[0013] Preferably, the first folding component is one of a hinge, a folding rod, or a hinge, and the second folding component is one of an elastic component or a flexible component.

[0014] Preferably, the outer periphery of the first clamping arm and the outer periphery of the second clamping arm are both covered with one or more of the following: polyester outer sleeve, cotton outer sleeve, polyester fiber outer sleeve, or nylon outer sleeve.

[0015] Both the first clamping component and the second clamping component are made of nickel-titanium or soft titanium stainless steel.

[0016] The beneficial effects of this invention are:

[0017] This invention features a novel structure and ingenious design. The first and second clamping components are foldable and deformable, with a wide and virtually unrestricted folding angle range. This invention facilitates clamping the atrial appendage, making it easier for doctors to operate and reducing surgical time. Under the elastic action of the elastic connector, the atrial appendage can be held in place after clamping. Since elastic connectors are provided at both ends, the clamping force formed between the first and second clamping components is uniform and balanced, effectively preventing the atrial appendage clamp from falling off and ensuring the safety and reliability of the surgery.

[0031] Example 1

[0032] A foldable ear clip structure includes a first clamping component 1 and a second clamping component 2 arranged in parallel. An elastic connector 3 is connected between one end of the first clamping component 1 and one end of the second clamping component 2, and between the other end of the first clamping component 1 and the other end of the second clamping component 2. The elastic connector 3 provides clamping force to the first clamping component 1 and the second clamping component 2. Preferably, the elastic connector 3 is an elastic ring. Both the first clamping component 1 and the second clamping component 2 are foldable and deformable structures. Both the first clamping component 1 and the second clamping component 2 are made of nickel-titanium or soft titanium stainless steel.

[0033] Specifically, in this embodiment 1, since both the first clamping component 1 and the second clamping component 2 are made of nickel-titanium or soft titanium stainless steel, the first clamping component 1 and the second clamping component 2 can be bent, achieving a folding effect. In use, before the surgeon inserts this embodiment 1 into the human body, the first clamping component 1 and the second clamping component 2 are folded and then inserted into the body in a folded state. After insertion, the atrial appendage clamp of this embodiment 1 is opened via an external conveyor and moved towards the atrial appendage 100. Then, the atrial appendage clamp is unfolded via the conveyor, thereby opening the gap between the first clamping component 1 and the second clamping component 2. The space opened between the first clamping component 1 and the second clamping component 2 is aligned with the root of the atrial appendage 100 and placed at that position. The delivery device releases the atrial appendage clamp, and under the elastic action of the elastic connector 3, the first clamping component 1 and the second clamping component 2 clamp the atrial appendage 100, so that the first clamping component 1 and the second clamping component 2 can maintain the clamping force on the atrial appendage 100, and the structure is stable and reliable. This embodiment 1 has a novel structure and ingenious design. The first clamping component 1 and the second clamping component 2 can be folded and deformed, and the folding angle range is wide and basically unrestricted. This embodiment 1 facilitates clamping the atrial appendage, facilitates the operation of doctors, and reduces the operation time. Under the elastic action of the elastic connector 3, it can also be maintained after the atrial appendage is clamped. Since the elastic connector 3 is provided at both ends, the clamping force formed between the first clamping component 1 and the second clamping component 2 is uniform and balanced, effectively preventing the atrial appendage clamp from falling off, and ensuring the safety and reliability of the operation.

[0034] In this embodiment 1, the first clamping component 1 and the second clamping component 2 can be as follows: Figure 1 It is a cylindrical shape, and because it is made of nickel-titanium or soft titanium stainless steel, it can be folded.

[0035] Of course, preferably, the first clamping assembly 1 is formed by connecting two first clamping arms 4 made of nickel-titanium or soft titanium stainless steel. A folding part is connected between the two first clamping arms 4. The folding part is made of nickel-titanium or soft titanium stainless steel. The first clamping arms 4 and the folding part are integrally formed. The cross-sectional width of the folding part is smaller than the cross-sectional width of the first clamping arms 4. The folding part can provide storage space when the two first clamping arms 4 are folded, thereby improving the folding range of this embodiment 1.

[0036] Example 2

[0037] The difference between Example 2 and Example 1 is as follows: Figure 3 , Figures 5 to 7As shown, the first clamping assembly 1 includes at least two first clamping arms 4 connected in sequence, with a first folding component 5 disposed between adjacent first clamping arms 4; the second clamping assembly 2 includes at least two second clamping arms 6 connected in sequence, with a second folding component 7 disposed between adjacent second clamping arms 6; wherein, the outer periphery of the first clamping arm 4 and the outer periphery of the second clamping arm 6 are both covered with one or more of polyester outer sleeves, cotton outer sleeves, polyester fiber outer sleeves, or nylon outer sleeves (not shown in the figure), under this configuration; the materials of the first clamping arm 4 and the second clamping arm 6 are preferably aluminum alloy or stainless steel, which are rigid materials with high strength and good clamping stability.

[0038] Preferably, there are two first clamping arms 4 and two second clamping arms 6.

[0039] Specifically, in use of Embodiment 2, before the surgeon inserts Embodiment 2 into the human body, the first clamping component 1 and the second clamping component 2 are folded and then inserted into the body in a folded state. That is, the two first clamping arms 4 are folded together side-by-side via the first folding component 5, and the two second clamping arms 6 are folded together side-by-side via the second folding component 7. After Embodiment 2 enters the human body, the atrial appendage clamp of Embodiment 2 is opened by an external conveyor and moved towards the atrial appendage 100. Then, the atrial appendage clamp is unfolded by the conveyor, opening the gap between the first clamping component 1 and the second clamping component 2. The space opened between the first clamping component 1 and the second clamping component 2 is aligned with the root of the atrial appendage and placed at the atrial appendage 100 position. Then, the conveyor opens the two first clamping arms 4 and the two second clamping arms 6, and the conveyor releases the atrial appendage clamp. The elastic connector 3... Under the elastic action, the two first clamping arms 4 and the two second clamping arms 6 clamp the atrial appendage 100, so that the first clamping component 1 and the second clamping component 2 can maintain the clamping force on the atrial appendage, and the structure is stable and reliable. This embodiment 2 has a novel structure and ingenious design. The two first clamping arms 4 and the two second clamping arms 6 achieve the folding effect under the first folding component 5 and the second folding component 7 respectively. The folding angle range is wide and basically unrestricted. This embodiment 2 is convenient for clamping the atrial appendage, which is convenient for doctors to operate and reduces the operation time. Under the elastic action of the elastic connector 3, the clamping effect of the first clamping component 1 and the second clamping component 2 can be maintained after the atrial appendage is clamped. Since the elastic connector 3 is provided at both ends, the clamping force formed between the first clamping component 1 and the second clamping component 2 is uniform and balanced, which effectively prevents the atrial appendage clamp from falling off and ensures the safety and reliability of the operation.

[0040] Of course, the number of the first clamping arm 4 and the number of the second clamping arm 6 in this embodiment 2 can be an even number, such as four, six, or eight.

[0041] Furthermore, both the first clamping arm 4 and the second clamping arm 6 are hollow structures, which reduces production costs and thus medical costs. Moreover, due to their hollow structure, they are lightweight, reducing the load on the auricle and providing greater benefits to patients.

[0042] In this embodiment 2, both the first folding component 5 and the second folding component 7 are either elastic or soft components. Specifically, elastic or soft components such as soft rubber, woven fabric, or polyester fabric can easily achieve the folding effect of the first folding component 5 and the second folding component 7, facilitating the folding of the first clamping assembly 1 and the second clamping assembly 2.

[0043] Example 3

[0044] The difference between Example 3 and Example 2 is as follows: Figure 4 As shown, both the first folding component 5 and the second folding component 7 are hinges, folding rods, or hinges. Specifically, the first folding component 5 and the second folding component 7 in this configuration can also achieve rotational folding between the two first clamping arms 4 and the two second clamping arms 6.

[0045] Example 4

[0046] The difference between Embodiment 4 and Embodiment 2 is that the first folding component 5 is either an elastic component or a flexible component, and the second folding component 7 is either a hinge, a folding rod, or a hinge.

[0047] Example 5

[0048] The difference between Embodiment 5 and Embodiment 2 is that the first folding component 5 is one of a hinge, a folding rod, or a hinge, and the second folding component 7 is one of an elastic component or a flexible component.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present invention without departing from the scope of the present invention are within the scope of the present invention.
