[0033] In order to make the above objectives, features and advantages of the application more apparent and understandable, the specific embodiments of the application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to fully understand the application. However, the application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the application, so the application is not limited to the specific embodiments disclosed below.

[0034] Referring toFigures 1 to 3 The application provides a novel fixing tool 100 which can realize positioning of the mounting seat and the mounting pipe and facilitate adhesive connection between the mounting seat and the mounting pipe. Figure 1 FIG. 1 is a schematic view of the fixing tool 100 according to an embodiment of the application, Figure 2 FIG. 2 is a sectional view of the fixing tool 100 shown in FIG. 1, and Figure 1 the sectional line is not drawn in FIG. 3, Figure 2 FIG. 4 is a schematic view of the fixing tool 100 shown in FIG. 1 positioning the catheter seat 200 and the hypotube 300. Figure 3 Figure 1 FIG. 5 is a schematic view of the fixing tool 100 shown in FIG. 1 positioning the catheter seat 200 and the hypotube 300.

[0035] In the embodiment, the mounting seat is the catheter seat 200, the mounting pipe is the hypotube 300, and the fixing tool 100 of the application mainly positions the connection between the catheter seat 200 and the hypotube 300 in a medical instrument. Of course, the mounting pipe can also be a catheter or other pipes matched with the catheter seat 200, and in other embodiments of the application, the fixing tool 100 can also position the connection between two components which require positioning accuracy.

[0036] Hereinafter, when the structure of the fixing tool 100 is described, the catheter seat 200 is used to replace the mounting seat, and the hypotube 300 is used to replace the mounting pipe. The connection principle when the mounting seat and the mounting pipe are other types is substantially the same as the connection principle of the catheter seat 200 and the hypotube 300 of the application, and will not be described again.

[0037] It can be understood that the fixing tool 100 of the application can be used independently, that is, after the catheter seat 200 and the hypotube 300 are mounted to the fixing tool 100, the positioning between the catheter seat 200 and the hypotube 300 is accurate, and the glue can be directly injected between the catheter seat 200 and the hypotube 300. After the glue is cured, the catheter seat 200 and the hypotube 300 are adhesively connected, and the fixed connection of the catheter seat 200 and the hypotube 300 is realized.

[0038] Of course, the fixing tool 100 of the application can also be used in cooperation with a curing device (not shown). The curing device has a UV light source (not shown), the fixing tool 100 positions the catheter seat 200 and the hypotube 300, and then the glue is injected between the catheter seat 200 and the hypotube 300. The UV light source can accelerate the curing of the glue and improve the assembly efficiency of the catheter seat 200 and the hypotube 300.

[0039] It is worth noting that the principle of the fixing tool 100 used independently or in cooperation with the curing device is substantially the same. The application only takes the fixing tool 100 used in cooperation with the curing device to position the catheter seat 200 and the hypotube 300 as an example for description.

[0040] ​The fixed tool 100 of the present application can realize the limiting installation of the catheter seat 200 and the hypotube 300, coaxially arrange the catheter seat 200 and the hypotube 300, facilitate the adhesive connection between the catheter seat 200 and the hypotube 300 in the later stage, ensure the reliability of the connection between the catheter seat 200 and the hypotube 300, and further ensure the use performance of the balloon dilatation catheter. In addition, the fixed tool 100 can facilitate the connection between the catheter seat 200 and the hypotube 300 and improve the operation efficiency. The specific structure of the fixed tool 100 in an embodiment is introduced below.

[0041] Referring to Figures 1 to 3 In an embodiment, the fixed tool 100 comprises a mounting seat 110 and a limiting seat 120. The limiting seat 120 is arranged on the mounting seat 110, and the limiting seat 120 has a mounting hole 121 at one end away from the mounting seat 110. The mounting hole 121 is coaxially arranged with the limiting seat 120. The catheter seat 200 is sleeved on the limiting seat 120 and is limitingly installed on the limiting seat 120. One end of the hypotube 300 is arranged in the mounting hole 121 through the catheter seat 200.

[0042] The mounting seat 110 is the base of the fixed tool 100. The mounting seat 110 is mounted on the mounting frame of the curing equipment through the mounting seat 110, so as to realize the mounting of the fixed tool 100 on the curing equipment. The limiting seat 120 is arranged on the mounting seat 110, and the limiting seat 120 is used for limitingly installing the catheter seat 200.

[0043] The catheter seat 200 is sleeved and mounted on the outside of the limiting seat 120. The limiting seat 120 can limit the catheter seat 200 along the axial direction of the limiting seat 120, so as to ensure that the catheter seat 200 is reliably limitingly installed on the limiting seat 120 and avoid the catheter seat 200 from moving along the axial direction of the limiting seat 120, thereby facilitating the positioning of the catheter seat 200 and the hypotube 300 in the later stage.

[0044] In addition, the limiting seat 120 has the mounting hole 121 at one end away from the mounting seat 110. The mounting hole 121 is coaxially arranged with the limiting seat 120 and is used for mounting one end of the hypotube 300. The mounting hole 121 can realize the limiting installation of the hypotube 300, so as to enable the limiting seat 120 to limit and fix the hypotube 300.

[0045] The fixed tool 100 of the present application can respectively install the catheter seat 200 and the hypotube 300, limit the catheter seat 200 and the hypotube 300, and coaxially position the catheter seat 200 and the hypotube 300. In this way, glue can be injected at the connection between the catheter seat 200 and the hypotube 300 in the later stage, so as to realize the adhesive connection between the catheter seat 200 and the hypotube 300.

[0046] When the fixed tool 100 is used to position the catheter seat 200 and the hypotube 300, the catheter seat 200 is first installed on the limiting seat 120, and the limiting seat 120 limits the catheter seat 200 to avoid the catheter seat 200 moving along the axial direction of the limiting seat 120. Then, one end of the hypotube 300 is inserted into the inner cavity of the catheter seat 200 through the catheter seat 200, and then the one end of the hypotube 300 is installed on the mounting hole 121 of the limiting seat 120.

[0047] At this time, the limiting seat 120 can limit the catheter seat 200, and the limiting seat 120 can also limit the hypotube 300 through the mounting hole 121, so that the limiting of the catheter seat 200 and the hypotube 300 is realized. Moreover, since the limiting seat 120 and the mounting hole 121 are coaxially arranged, after the limiting seat 120 limits the catheter seat 200 and the hypotube 300, the coaxiality of the catheter seat 200 and the hypotube 300 can be ensured, and the position between the catheter seat 200 and the hypotube 300 is accurate.

[0048] Then, glue is injected at the end of the catheter seat 200 away from the mounting seat 110, and the glue can fill the gap between the catheter seat 200 and the hypotube 300. After the glue solidifies, the glue can bond the catheter seat 200 and the hypotube 300, and the fixation of the catheter seat 200 and the hypotube 300 is realized. After the catheter seat 200 and the hypotube 300 are fixed, the catheter seat 200 and the hypotube 300 are detached from the fixed tool 100.

[0049] The fixed tool 100 of the above embodiment realizes the limiting installation of the catheter seat 200 and the hypotube 300 through the limiting seat 120, and the catheter seat 200 and the hypotube 300 are coaxially arranged. In this way, the glue can be injected between the catheter seat 200 and the hypotube 300, the coaxial fixed connection of the catheter seat 200 and the hypotube 300 is realized, the reliability of the connection between the catheter seat 200 and the hypotube 300 is ensured, and then the use performance of the balloon dilatation catheter is ensured. At the same time, the connection between the catheter seat 200 and the hypotube 300 can be facilitated, and the operation efficiency is improved.

[0050] Referring to Figures 1 to 3 In an embodiment, the limiting seat 120 is conically arranged and is matched with the shape of the inner cavity of the catheter seat 200. The catheter seat 200 can be installed along the axial direction of the limiting seat 120 and can rotate relative to the limiting seat 120.

[0051] The limiting seat 120 is conical as a whole, and the diameter of the end of the limiting seat 120 away from the mounting seat 110 is smaller than the diameter of the end of the limiting seat 120 connected with the mounting seat 110. The inner cavity of the catheter seat 200 is also conical. In this way, after the catheter seat 200 is installed to the limiting seat 120, the conical cooperation relationship can reliably install the catheter seat 200 to the limiting seat 120, avoiding the axial movement of the catheter seat 200 along the limiting seat 120.

[0052] At the same time, the catheter seat 200 can also rotate relative to the limiting seat 120, that is, the catheter seat 200 can rotate around the central axis of the limiting seat 120. After the glue is injected between the catheter seat 200 and the hypodermic tube 300, the catheter seat 200 drives the hypodermic tube 300 to rotate through the glue, so that the glue at each position around the catheter seat 200 can be aligned with the UV light source, realizing the rapid curing of the glue and improving the efficiency of the connection between the catheter seat 200 and the hypodermic tube 300.

[0053] In an embodiment, the limiting seat 120 is made of an elastic material to provide elastic support and ensure the concentricity of the catheter seat 200 and the hypodermic tube 300. That is, the limiting seat 120 is made of a material with a certain elasticity to make the limiting seat 120 have a certain elastic property. In this way, the elastic limiting seat 120 can accurately provide elastic support for the catheter seat 200, avoiding the axial movement of the catheter seat 200 along the limiting seat 120, and at the same time, the elastic limiting seat 120 can also realize the reliable limiting of the hypodermic tube 300, avoiding the hypodermic tube 300 from separating from the mounting hole 121, and ensuring the concentricity of the catheter seat 200 and the hypodermic tube 300.

[0054] In an embodiment, the limiting seat 120 is made of a material such as silicone or rubber. In this way, the limiting seat 120 has a certain elasticity, and the elastic limiting seat 120 can accurately limit the catheter seat 200, avoiding the axial movement of the catheter seat 200 along the limiting seat 120, and at the same time, the elastic limiting seat 120 can also realize the reliable limiting of the hypodermic tube 300, avoiding the hypodermic tube 300 from separating from the mounting hole 121.

[0055] Referring to Figures 1 to 3 In an embodiment, the inner diameter of the mounting hole 121 is less than or equal to the outer diameter of the hypodermic tube 300 to realize the limiting of the hypodermic tube 300. That is, the inner diameter of the mounting hole 121 is the same as the outer diameter of the hypodermic tube 300, or the inner diameter of the mounting hole 121 is slightly smaller than the outer diameter of the hypodermic tube 300.

[0056] Thus, after one end of the hypotube 300 is mounted to the mounting hole 121, the hypotube 300 can be fixed to the mounting hole 121, avoiding the hypotube 300 from being separated from the fixing hole 114. At the same time, since the limiting seat 120 is made of elastic material, after the hypotube 300 is mounted to the mounting hole 121, the elastic limiting seat 120 can fix the end of the hypotube 300, realizing reliable limiting of the hypotube 300.

[0057] Referring to Figures 1 to 3 In an embodiment, the limiting seat 120 also has a guide hole 122, which is arranged at one end of the mounting hole 121 away from the mounting seat 110 and communicates with the mounting hole 121. The diameter of the guide hole 122 gradually decreases from the end away from the mounting hole 121 to the end close to the mounting hole 121, for guiding the hypotube 300 to be inserted into the mounting hole 121.

[0058] The guide hole 122 is of a flared structure and is arranged at one end of the mounting hole 121 away from the mounting seat 110. The diameter of the end of the guide hole 122 connected with the mounting seat 110 is adapted to the inner diameter of the mounting hole 121, and the diameter of the end of the guide hole 122 away from the mounting seat 110 is greater than the diameter of the mounting hole 121 and gradually decreases in the direction towards the mounting seat 110.

[0059] Thus, the guide hole 122 and the mounting hole 121 can form a funnel-shaped structure, and the guide hole 122 can play a guiding role. When one end of the hypotube 300 is inserted into the mounting hole 121, the hypotube 300 first contacts the guide hole 122 and moves along the guide hole 122, facilitating the mounting of the hypotube 300 into the mounting hole 121.

[0060] Referring to Figures 1 to 3 In an embodiment, the mounting seat 110 includes a mounting body 111 and a connecting body 112, and one end of the mounting body 111 is connected with the limiting seat 120. The end of the mounting body 111 away from the limiting seat 120 is connected with the connecting body 112, and the connecting body 112 is mounted to the mounting frame of the curing equipment.

[0061] The mounting body 111 is a main component of the mounting seat 110 and supports the limiting seat 120. The limiting seat 120 is arranged at one end of the mounting body 111, and the connecting body 112 is arranged at the end of the mounting body 111 away from the limiting seat 120. After the mounting body 111 is arranged, the mounting body 111 can facilitate the assembly of the connecting body 112 and the mounting frame of the curing equipment, so that the mounting seat 110 is fixed to the mounting frame through the connecting body 112, realizing the mounting of the fixing tool 100 to the curing equipment.

[0062] In an embodiment, the mounting body 111 and the connecting body 112 are in an integrated structure. In this way, the structural strength of the mounting seat 110 can be ensured, and the mounting body 111 and the connecting body 112 can be prevented from being broken at the connection. Of course, in other embodiments of the present application, the mounting body 111 and the connecting body 112 can be separately arranged and fixed by means of gluing or threaded connection.

[0063] Referring to Figures 1 to 3 In an embodiment, the mounting seat 110 further comprises a connecting thread 113 arranged at one end of the mounting seat 110 away from the limiting seat 120. The mounting seat 110 is fixed to the mounting frame of the curing equipment through the connecting thread 113, so as to realize quick mounting and dismounting. In this way, the mounting seat 110 is mounted to the mounting frame through the threaded connection, so as to facilitate quick mounting and dismounting of the mounting seat 110.

[0064] Further, the connecting thread 113 is arranged on the outer circumferential surface of the connecting body 112, and the connecting body 112 is connected to the mounting frame through the connecting thread 113, so as to realize connection of the mounting seat 110 and the mounting frame. Of course, in other embodiments of the present application, the connecting body 112 can also be mounted to the mounting frame through clamping or other detachable ways.

[0065] Of course, in other embodiments of the present application, the mounting seat 110 can also be mounted to the mounting frame through clamping or other ways capable of realizing quick mounting and dismounting.

[0066] Referring to Figures 1 to 3 In an embodiment, the limiting seat 120 is coaxially arranged with the mounting seat 110. That is, the limiting seat 120 and the mounting seat 110 also need to ensure coaxiality during processing, so as to ensure coaxiality of the mounting hole 121 and the limiting seat 120.

[0067] Referring to Figures 1 to 3 In an embodiment, the mounting seat 110 and the limiting seat 120 adopt a separate structure and are fixed through threaded connection, clamping or gluing. That is, the mounting seat 110 and the limiting seat 120 can adopt a separate structure, and during assembly, the mounting seat 110 and the limiting seat 120 are reliably connected through threaded connection, clamping or gluing, so as to prevent the mounting seat 110 and the limiting seat 120 from being separated during use, and ensure accuracy of limiting the catheter seat 200 and the hypotube 300.

[0068] Referring to Figures 1 to 3In an embodiment of the present application, the mounting base 110 has a fixing hole 114, and the limiting seat 120 has a mounting portion 123 at one end thereof, which is mounted in the fixing hole 114 to fix the limiting seat 120 to the mounting base 110. When the limiting seat 120 is mounted to the mounting base 110, the mounting portion 123 of the limiting seat 120 is mounted to the fixing hole 114 of the mounting base 110, and the mounting portion 123 is limited by the fixing hole 114 to ensure that the limiting seat 120 is reliably mounted to the mounting base 110.

[0069] Further, the mounting portion 123 and the fixing hole 114 are fixedly connected by a clamping portion such as a buckle. Of course, the mounting portion 123 and the fixing hole 114 can also be fixed by a threaded connection, or can be fixed by a glueing method, or by an interference fit.

[0070] Of course, in other embodiments of the present application, the mounting base 110 and the limiting seat 120 are an integral structure. In this way, the structural strength of the mounting base 110 and the limiting seat 120 can be ensured, and the mounting base 110 and the limiting seat 120 can be prevented from separating at the connection, and the limiting effect on the catheter seat 200 and the hypotube 300 can be ensured.

[0071] The fixing tool 100 of the present application has the limiting seat 120 arranged on the mounting base 110, and the limiting seat 120 is used to limit and fix the catheter seat 200. Meanwhile, a mounting hole 121 is arranged at one end of the limiting seat 120, and the mounting hole 121 is used to limit the hypotube 300. In this way, the catheter seat 200 and the hypotube 300 can be limited, and coaxial fixed connection of the catheter seat 200 and the hypotube 300 can be achieved. The reliability of the connection between the catheter seat 200 and the hypotube 300 can be ensured, and the use performance of the balloon dilatation catheter can be ensured. Meanwhile, the connection between the catheter seat 200 and the hypotube 300 can be facilitated, the operation efficiency can be improved, and the bonding effect can be ensured.

[0072] Further, a guide hole 122 is arranged at one end of the mounting hole 121, so that the mounting hole 121 and the guide hole 122 have a funnel structure. This facilitates the installation of the hypotube 300, and the hypotube 300 can be completely fixed to avoid shaking. Furthermore, the limiting seat 120 is made of a material such as silicone or rubber, which facilitates the limiting of the catheter seat 200 and the hypotube 300 by the limiting seat 120. Meanwhile, the mounting base 110 is arranged on a mounting frame of a curing device to support the catheter seat 200 and the hypotube 300. This facilitates the injection of glue between the catheter seat 200 and the hypotube 300, and facilitates the irradiation by a UV light source to cure the glue, and ensures the reliability of the bonding connection between the catheter seat 200 and the hypotube 300.

[0073] The application also provides a curing device, comprising a mounting frame, a UV light source and the fixing tool 100 in any of the above embodiments. The fixing tool 100 and the UV light source are arranged in the mounting frame, and the fixing tool 100 is used to limit the installation of the hypotube 300 and the catheter seat 200. The UV light source is used to irradiate the glue at the connection between the hypotube 300 and the catheter seat 200, so as to realize the bonding connection between the hypotube 300 and the catheter seat 200.

[0074] The curing device of the application can realize the reliable positioning of the catheter seat 200 and the hypotube 300 after the fixing tool 100 of the above embodiments is used. After the glue is injected between the catheter seat 200 and the hypotube 300, the UV light source can irradiate the glue at the connection between the hypotube 300 and the catheter seat 200, so as to realize the bonding connection between the hypotube 300 and the catheter seat 200.

[0075] It should be noted that the curing device of the application uses a UV light source (UV ultraviolet) to solidify. The glue here refers to UV glue, that is, the glue that can be solidified after being irradiated by the ultraviolet light source, which will not be described in the application.

[0076] The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described. However, as long as the combination of the technical features does not exist, it should be considered as the scope of the description.

[0077] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as the limitation of the patent application scope.
