Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a sealing device and a puncture device. Background Technology

[0002] A thrombus is a small mass that forms on the surface of a blood vessel in the cardiovascular system at a point where blood has broken off or been repaired. Thrombosacs can cause serious harm to human health; for example, they can cause ischemia symptoms in the corresponding organs and severe symptoms such as limb necrosis. If a thrombus forms in a blood vessel, it can cause a blockage in blood flow. Thromboembolism can lead to a reduction in blood supply to organs or tissues, or the deposition of blood in certain organs or tissues, resulting in organ failure or dysfunction. Thromboembolic diseases are very common in clinical practice and seriously endanger human life and health.

[0003] Clinically, for cases of vascular embolism and thrombus accumulation, interventional surgery using thrombectomy devices is often employed to destroy and remove the thrombus. At the start of the procedure, the surgeon uses a puncture device to penetrate the vessel wall and create a channel to introduce the thrombectomy device into the blood vessel. In current technology, the sealing valve in the puncture device is often designed with a single-line or cross-shaped perforation. This type of sealing valve is prone to problems such as difficulty in penetrating the puncture tube and seal failure during insertion, increasing the difficulty of the procedure and potentially leading to the failure of the entire puncture device.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] Reference Figures 1a-1f As shown, according to one embodiment of this application, a sealing device 1 is provided. The sealing device 1 includes at least one body portion 11, the body portion 11 including: a first end face 111, a second end face 112 and a side wall 113, the first end face 111 and the second end face 112 being disposed opposite to each other; the side wall 113 being disposed between the first end face 111 and the second end face 112.

[0040] It also includes a through hole 101 and a slit 102. The through hole 101 is disposed through the first end face 111 and the second end face 112, with one end of the through hole 101 located in the middle of the first end face 111 and the other end located in the middle of the second end face 112. The slit 102 is disposed through the first end face 111 and the second end face 112, and the slit 102 is spaced apart from the through hole 101. Multiple slits 102 are provided, and the multiple slits 102 are distributed at intervals around the through hole 101.

[0041] The sealing device 1 provided in this application embodiment can be installed in a puncture device. During use, the puncture tube of the puncture device passes through the sealing device 1. Specifically, the sealing device 1 is installed inside the housing of the puncture device, and the puncture tube passes through the sealing device 1 via a through-hole 101 located in the middle of the sealing device 1. The sealing device 1 ensures a good seal within the puncture tube, preventing leakage and spillage of blood or other fluids within the puncture device. Furthermore, the sealing device 1 effectively prevents external bacteria, viruses, and other microorganisms from entering the puncture device, thereby reducing the risk of infection.

[0042] The sealing device 1 is made entirely of an elastic material, such as silicone. In its natural state, the slit 102 surrounding the through hole 101 has a hollow, open structure. When the sealing device 1 is installed inside the housing of the puncture device and is passed through by the puncture tube of the puncture device, on the one hand, the side wall 113 of the sealing device 1 is abutted by the housing of the puncture device, and on the other hand, the puncture tube squeezes the sealing device 1 as it passes through the through hole 101. As a result, the sealing device 1 undergoes elastic deformation at the slit 102, causing the slit 102 to close, thus isolating the interior from the exterior and achieving a sealing effect.

[0043] In the prior art, such sealing devices often have a cross-shaped through hole in the middle for the puncture tube to pass through. During the insertion of the puncture tube, especially when a flat-headed puncture tube without a pointed or inclined structure is inserted, the sealing device in the prior art cannot provide strong elastic support for the puncture tube. It is easy for the puncture tube to be rolled into the inside of the puncture tube, resulting in the failure of the puncture tube to pass through the sealing device. The sealing device cannot play a sealing role on the outer periphery of the puncture tube.

[0044] In the sealing device 1 provided in this application embodiment, since a plurality of slits 102 are provided at intervals around the through hole 101, that is, the slits 102 are not connected to the through hole 101, and the plurality of slits 102 are not connected to each other; when the puncture tube passes through the through hole 101, the structure between the through hole 101 and the slits 102 and between the plurality of slits 102 can provide good elastic support for the puncture tube; and since the sealing device 1 can undergo elastic deformation at the through hole 101 and the slits 102, it can ensure that the puncture tube passes smoothly through the sealing device 1, and the sealing device 1 can play an effective sealing role on the outer periphery of the puncture tube.

[0045] Reference Figure 1b , Figure 1c As shown, in one embodiment, the cross-sectional shape of the through hole 101 is circular; the cross-sectional shape of the slit 102 is arc-shaped.

[0046] In this specific example, the circular cross-sectional through-hole 101 can well fit the shape of the puncture tube, ensuring that the puncture tube fits tightly with the sealing device 1 at the through-hole 101 after passing through smoothly; the arc-shaped slit 102 can provide good elastic deformation allowance around the through-hole 101.

[0047] Reference Figure 1b , Figure 1c As shown, in one embodiment, a plurality of the slit portions 102 are evenly spaced around the through-hole portion 101.

[0048] In this specific example, multiple slits 102 are evenly spaced around the through hole 101, so that the structure between every two adjacent slits 102 can provide uniform elastic support for the puncture tube; and each slit 102 can undergo uniform elastic deformation.

[0049] For example, a total of six slits 102 may be provided, and the six slits 102 may be evenly distributed around the through hole 101.

[0050] Reference Figure 1b , Figure 1c As shown, in one embodiment, the distance between two adjacent slit portions 102 gradually increases along the direction gradually moving away from the through hole portion 101. Furthermore, the width of the slit portion 102 gradually increases along the direction gradually moving away from the through hole portion 101.

[0051] In this specific example, near the through-hole 101, the slit 102 is narrower and the distance between adjacent slits 102 is also smaller; far from the through-hole 101, the slit 102 is wider and the distance between adjacent slits 102 is also larger. Thus, near the through-hole 101, the sealing device 1 provides strong elastic support for the puncture tube, while far from the through-hole 101, the sealing device 1 can undergo greater elastic deformation; thereby ensuring that the puncture tube passes smoothly through the through-hole 101.

[0052] Reference Figure 1a As shown, in one embodiment, the distance between the first end face 111 and the second end face 112 gradually decreases along the direction that gradually approaches the through hole portion 101.

[0053] In this specific example, the sealing device 1 is thinnest at the position corresponding to the through hole 101, so that the puncture resistance at the through hole 101 is small, which helps the puncture tube to pass smoothly through the through hole 101.

[0054] Reference Figure 1dAs shown, in one embodiment, the first end face 111 includes a first protrusion 1111 and a first recess 1112, the first protrusion 1111 and the first recess 1112 being alternately connected; and / or, the second end face 112 includes a second protrusion 1121 and a second recess 1122, the second protrusion 1121 and the second recess 1122 being alternately connected.

[0055] In this specific example, the first end face 111 and / or the second end face 112 exhibit an approximately wavy shape. For example, the first end face 111 includes multiple first protrusions 1111 and multiple first recesses 1112 of the same or different sizes, and the second end face 112 includes multiple second protrusions 1121 and multiple second recesses 1122 of the same or different sizes. By designing the dimensions and arrangement of the first protrusions 1111, the first recesses 1112, the second protrusions 1121, and the second recesses 1122, the thickness of the sealing device 1 is minimized at the location corresponding to the through hole 101, thereby reducing puncture resistance.

[0056] Reference Figures 1a to 1c As shown, in one embodiment, the body portion 11 further includes a boss portion 114, which is connected to the outside of the sidewall 113.

[0057] In this specific example, the boss portion 114 disposed on the outer side of the sidewall 113 can improve the sealing performance of the sealing device 1. Optionally, the boss portion 114 can be an integral annular structure or a discrete structure.

[0058] Reference Figure 1e , Figure 1f As shown, in one embodiment, the sealing device 1 includes two body parts 11, which are stacked and connected along the thickness direction, and a cavity part 110 is formed between the two body parts 11.

[0059] In this specific example, the sealing device 1 includes two body portions 11 stacked along the thickness direction, which achieves a double sealing effect, thereby improving the sealing performance of the sealing device 1. Furthermore, both body portions 11 of the sealing device 1 have their thinnest thickness at the position corresponding to the through hole portion 101, thus forming a cavity portion 110 between the two body portions 11. This effectively reduces puncture resistance, allowing the puncture tube to pass smoothly through the second body portion 11 after being buffered by the cavity portion 110 after passing through one body portion 11.

[0060] According to another embodiment of this application, refer to Figure 2As shown, a puncture device is provided, which includes the sealing device 1 as described above.

[0061] The puncture device provided in this application embodiment has high sealing performance and the puncture operation can be carried out smoothly because it includes the sealing device 1 mentioned above.

[0062] Reference Figure 2 As shown, in one embodiment, the puncture device further includes a first housing 21, a second housing 22, a Luer connector 3, and a puncture tube 4; the first housing 21, the second housing 22, and the Luer connector 3 are all hollow structures, and the first housing 21 is connected between the second housing 22 and the Luer connector 3; the sealing device 1 is disposed inside the first housing 21 and located between the second housing 22 and the Luer connector 3; a portion of the puncture tube 4 is disposed inside the hollow structure of the first housing 21, the second housing 22, and the Luer connector 3, and the puncture tube 4 passes through the through hole 101 into the sealing device 1.

[0063] In this specific example, the first housing 21 and the second housing 22 can be connected by interlocking. The Luer connector 3 is sleeved on the end of the first housing 21 away from the second housing 22. The hollow structures of the Luer connector 3, the first housing 21, and the second housing 22 are interconnected. The sealing device 1 is disposed inside the first housing 21 and located between the second housing 22 and the Luer connector 3. During the process of the puncture tube 4 passing through the Luer connector 3, the first housing 21, and the second housing 22 in sequence, the puncture tube 4 needs to pass through the through hole 101 opened in the middle of the sealing device 1. The sealing device 1 with the above structure can ensure that the puncture tube 4 passes smoothly, and the sealing device 1 can play an effective sealing role on the outer periphery of the puncture tube 4.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
