[0044] The guidewire catheter sealing structure of the Y-tube connector for interventional surgery of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.
[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0046] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0047] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0048] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0049] like Figure 1-Figure 6 As shown, the guidewire catheter sealing structure of the Y-tube connector for interventional surgery includes: a sealing shell 01 that passes through the guidewire catheter and a roller 02 that compresses and seals the guidewire catheter. In order to achieve that the roller 02 can compress and seal the guidewire catheter during the rolling process, and can also roll away from the guidewire catheter to relax the guidewire catheter. The roller 02 is connected to the inside of the sealing shell 01 in a rolling manner, and the rolling groove 03 of the roller 02 is inclined, so that the roller 02 can compress the guidewire catheter or move away from the guidewire catheter during the rolling process;
[0050] In order to limit the position of the guidewire catheter and ensure the compression and sealing effect, the sealing housing 01 has a catheter groove 1 at the bottom, and a guidewire groove 2 at the bottom of the catheter groove 1; the catheter groove 1 constrains the position of the guidewire catheter to ensure that the guidewire catheter can be compressed during the compression and sealing process to improve the sealing effect.
[0051] In order to compress and seal the catheter guide wire, especially to cooperate with the catheter groove 1 and the guide wire groove 2 structure to improve the sealing effect of the guide wire catheter, the outer wall of the roller 02 is convexly provided with a catheter convex ring 3, and the middle of the catheter convex ring 3 is provided with a guide wire ring groove 4. The catheter convex ring 3 extends into the catheter groove 1, and the guide wire ring groove 4 and the guide wire groove 2 form a guide wire passing cavity.
[0052] In order to compress and seal the guidewire catheter and ensure the tightness of the catheter and the guidewire, the cross section of the catheter groove 1 is semicircular, and the radius of the catheter groove 1 is the same as the radius of the guidewire catheter.
[0053] In order to maximize the compression and sealing effect with the outside of the guide wire during the compression and sealing process, the cross section of the guide wire groove 2 is semicircular, the radius of the guide wire groove 2 is greater than the radius of the guide wire, and the radius of the guide wire groove 2 is less than the sum of the radius of the guide wire and the thickness of the catheter wall of the catheter. Since the material of the guide wire catheter has a certain toughness, it can have appropriate compression deformation during the compression and sealing process to improve the sealing effect on the outer wall of the guide wire.
[0054] In order to ensure the cooperation between the roller 02 and the catheter groove 1, and to ensure that the guidewire catheter is compressed and deformed to the greatest extent during the sealing process, thereby achieving the sealing effect of the guidewire catheter, the cross section of the catheter convex ring 3 is semicircular, and the radius of the catheter convex ring 3 is the same as the radius of the guidewire catheter.
[0055] In order to leave enough space for the guide wire to pass through during the compression and sealing process, and to minimize the influence of the guide wire on the compression and sealing of the catheter, the cross section of the guide wire annular groove 4 is semicircular, and the radius of the guide wire annular groove 4 is the same as the radius of the guide wire groove 2. Therefore, when the maximum compression and sealing is achieved, the guide wire annular groove 4 and the guide wire groove 2 enclose a space for the guide wire to pass through, and the guide wire catheter is compressed to the maximum extent to ensure the sealing effect.
[0056] In order to ensure that the deformed guidewire catheter can be smoothly deformed during the compression and sealing process, reduce damage to the guidewire catheter, and ensure the long-term use effect of the guidewire catheter, the two sides of the guidewire groove 2 and the catheter groove 1 are smoothly transitioned; the two sides of the guidewire ring groove 4 and the catheter convex ring 3 are smoothly transitioned.
[0057] Similarly, in order to avoid the roller 02 from deforming smoothly during the compression and sealing process, the guidewire catheter has an arc transition between the catheter convex ring 3 and the outer wall of the roller 02, and between the catheter groove 1 and the bottom of the sealing housing 01, and the transition radius of the two arc transitions is the same.
[0058] In order to achieve the cooperation between the sealing shell 01 and the guidewire catheter and ensure the connection with the guidewire catheter. The sealing shell 01 includes: a bottom shell 5, a side wall 6 and an end wall 7. The side walls 6 are integrally formed on both sides of the bottom shell 5, and the end walls 7 are integrally formed on both ends of the bottom shell 5. In order to ensure sufficient compression deformation area, improve the realization of various sealing requirements, and facilitate control, the catheter groove 1 and the guidewire groove 2 are opened in the middle length direction of the upper surface of the bottom shell 5;
[0059] In order to achieve the goal of fixing the roller 02 after reaching the set sealing position during the sealing process, and to ensure that the set sealing effect position can be stable for a long time, the side wall 6 is provided with a rolling groove 03, the bottom surface of the rolling groove 03 is in the shape of a rack, and the outer wall of the roller shaft 04 of the roller 02 is provided with a tooth groove; through the cooperation between the tooth groove and the rack, the position of the roller 02 is limited and fixed.
[0060] Of course, in order to facilitate the operation of the roller 02, the upper side of the sealing housing 01 is open, the diameter of the roller 02 is greater than the maximum height of the side wall 6, and the upper side of the roller 02 extends out of the opening. The user can push and roll the roller 02 extending out of the sealing housing 01, thereby adjusting the sealing effect.
[0061] In order to meet the extension of the guidewire catheter, the end wall 7 is provided with an extension hole 9;
[0062] In order to cooperate with the catheter groove 1 and the guide wire groove 2, the lower side of the extension hole 9 is connected to the catheter groove 1 and the guide wire groove 2;
[0063] In order to ensure the smooth extension of the guide wire catheter, a certain limiting effect can be provided to the guide wire catheter. The upper side of the extension hole 9 and the catheter groove 1 are on the same circumference, and the diameter of the circumference is the same as the guide wire catheter diameter.
[0064] In order to ensure that sufficient deformation space is left for the guidewire catheter during the compression and sealing process, the two sides of the extension hole 9 are arc-shaped transitions, and the maximum transverse dimension of the extension hole 9 is greater than or equal to the circumference of the guidewire catheter.
[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
