Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a guide wire feeding fixture. Background Technology
[0002] A guidewire is a slender, flexible metal or composite wire structure commonly used in medical, industrial, and communications fields. Its function is to guide, position, support, or deliver. In the medical field, the guidewire is a commonly used interventional device that reaches the target site by inserting into the body's lumen. Some guidewires are also used in cardiac and neurological surgeries, where high safety requirements are necessary. The surface of the guidewire needs to be coated with a special functional coating to give it lubrication and other functional properties, and to allow it to integrate with the human body environment. Guidewires are conventionally stored in coils. In existing guidewire coating processes, to avoid guidewire tangling and adhesion, the coil is often fixed to a fixture, and the guidewire to be coated is pulled out, passed through a hole, and inserted into the coating solution for coating. This method is inconvenient and time-consuming, and there is also a risk of scratching the guidewire by the hole wall. Therefore, there is an urgent need to design a convenient and safe guidewire loading fixture. Utility Model Content

[0018] One end of the elastic element is located in the mounting groove, and the other end is sleeved on the protrusion.
[0019] Optionally, the clamping assembly further includes:
[0020] An operating element is located on the outside of the mounting plate and connected to the first part. The operating element is configured to move the connecting element when pulled, so that the first part moves away from the mounting plate.
[0021] Optionally, the top of the box body is provided with a plurality of first limiting grooves, the plurality of first limiting grooves are arranged at intervals along the extension direction of the box body, and each first limiting groove is used to place a disc-shaped guide wire;
[0022] The box body has multiple vertically arranged baffles inside, which are spaced apart along the extension direction of the box body. Each baffle corresponds to a first limiting groove for limiting the disc-shaped guide wire.
[0023] Optionally, the through groove has an opening that faces upward or downward.
[0024] Optionally, the front side of the mounting plate is provided with at least one second limiting groove, each second limiting groove being located below one of the clamping components.

[0042] Figure 1 This is a schematic structural diagram of a guide wire feeding fixture 100 according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic enlarged view of part A in the diagram. Figure 3 This is a schematic structural diagram of a disc-shaped guide wire 200 placed on a guide wire feeding fixture 100 according to an embodiment of the present invention. Figure 4 yes Figure 3 A schematic enlarged view of section B, where the arrows indicate the reciprocating movement direction of the clamping component. (See diagram below.) Figures 1 to 4As shown, in one specific embodiment, the guide wire feeding fixture 100 includes a housing 10, a mounting plate 20, and at least one clamping assembly. The housing 10 is used to hold a disc-shaped guide wire 200, the guide wire 200 having an open section 210. The mounting plate 20 is mounted on one side of the housing 10 and has at least one through slot 21. Each clamping assembly includes an elastic member 50 and a connector 40, the connector 40 passing through the through slot 21 and having a first portion 41 and a second portion 42 located on both sides of the mounting plate 20. One end of the elastic member 50 abuts against one side of the mounting plate 20, and the other end abuts against the second portion 42. When the connector 40 is pulled, the first portion 41 moves away from the mounting plate 20 and compresses the elastic member 50, allowing the open section 210 to pass between the first portion 41 and the mounting plate 20. When the connector 40 is released, the elastic member 50 returns to its original position, causing the first portion 41 to return to its original position, thus clamping the open section 210 between the first portion 41 and the mounting plate 20. Here, the disc-shaped guidewire 200 is a product such as Zebra guidewire or micro guidewire, and it comes with a protective sleeve or coil.
[0043] In this embodiment, the open section 210 of the guide wire 200 can be clamped by pulling and releasing the operating component 30. The operation process is simple and quick.
[0044] In some embodiments, the connector 40 further includes a third portion 43, which is arranged in the through groove 21 along the thickness direction of the mounting plate 20. The two ends of the third portion 43 are respectively connected to the first portion 41 and the second portion 42. It can be understood that the third portion 43 passes through the through groove 21 of the mounting plate 20, and the through groove 21 positions the third portion 43 and guides it when it moves.
[0045] In some embodiments, the first portion 41 and the second portion 42 are arranged in parallel and perpendicular to the third portion 43. This can be understood as the first portion 41 and the second portion 42 extending and bending along opposite sides of the third portion 43, with a bending angle of 90°. Here, the structure of the first portion 41, the second portion 42, and the third portion 43 includes, but is not limited to, plate-like, perforated, strip-like, or combinations thereof.
[0046] In some embodiments, when the connector 40 is pulled, a guide wire receiving space is formed between the first portion 41 and the mounting plate 20. The guide wire receiving space has an opening 441 arranged along the extension direction of the guide wire 200, and the open segment 210 is inserted into the guide wire receiving space from the opening 441. It can be understood that one side of the guide wire receiving space corresponding to the extension direction of the guide wire is open, and the guide wire 200 can be inserted into the guide wire receiving space through the opening 441. This insertion has very low precision requirements and can quickly achieve the feeding of the guide wire 200.
[0047] In some embodiments, the third part 43 can be connected to one side of the first part 41 to form a guidewire receiving space, or it can be connected to the middle part of the first part 41 to form two guidewire receiving spaces.
[0048] In some embodiments, there are multiple through slots 21, which are spaced apart along the extension direction of the mounting plate 20, with each pair of adjacent through slots 21 corresponding to a connector 40. Each connector 40 corresponds to a disc-shaped guide wire 200. The connector 40 also includes a fourth portion 44 parallel to the third portion 43, which is arranged in adjacent through slots 21. One end of the fourth portion 44 is connected to the second portion 42, and the other end forms an opening 441 between it and the first portion 41. Installing one connector 40 requires two through slots 21, with the third portion 43 and the fourth portion 44 respectively installed in the two through slots 21. When the connector 40 is pulled, the third portion 43 and the fourth portion 44 move along their respective through slots 21. The structure of the fourth portion 44 includes, but is not limited to, a plate-like shape, a perforated shape, a strip-like shape, or a combination thereof.
[0049] In some embodiments, the guidewire feeding fixture 100 further includes a gasket 60, which is installed on the side of the first portion 41 facing the mounting plate 20, and / or on the side of the mounting plate 20 facing the first portion 41, for contacting the open section 210. The gasket 60 is made of a soft material to protect the guidewire and prevent scratches. Additionally, the gasket 60 can also press the guidewire, using its friction to limit guidewire movement. Here, the gasket 60 is made of silicone.
[0050] In some embodiments, the mounting plate 20 is coated with a protective coating to provide special protection for the guidewire, so that contact with the guidewire will not have an adverse effect.
[0051] Figure 5 This is a schematic cross-sectional view of a clamping assembly according to an embodiment of the present invention. Figure 5 As shown, in some embodiments, the second portion 42 has a protrusion 421 on the side facing the mounting plate 20, and the mounting plate 20 has a mounting groove 22 on the side facing the second portion 42. One end of the elastic member 50 is located in the mounting groove 22, and the other end is sleeved on the protrusion 421. This embodiment can limit the two ends of the elastic member 50 by setting the protrusion 421 and the mounting groove 22 respectively. Here, see Figure 5 Each clamping assembly includes two elastic elements 50, which are arranged vertically at intervals to improve the stability of the clamping assembly during operation. In this embodiment, the elastic element 50 is a spring. In other embodiments, the elastic element 50 may also be a leaf spring or other component with the same properties as a spring.
[0052] In some embodiments, the clamping assembly further includes an operating member 30 located outside the mounting plate 20 and connected to the first portion 41. The operating member 30 is configured to move the connector 40 when pulled, causing the first portion 41 to move away from the mounting plate 20. The operating member 30 has a pulling structure, which is not particularly required; simply pulling the pulling structure will move the connector 40 toward the outside of the mounting plate 20. Furthermore, the operating member 30 has an operating hole 31 for inserting a finger. When it is necessary to clamp the open section 210 of the guidewire, the operator's finger passes through the operating hole 31 and pulls forward, thereby moving the connector 40 toward the outside of the mounting plate 20. At this time, the first portion 41 separates from the mounting plate 20, and the elastic member 50 is compressed by the second portion 42. Then, the open section 210 of the guidewire 200 is inserted from the opening 441 into the space between the first portion 41 and the mounting plate 20, i.e., within the guidewire receiving space. Finally, the operator releases the operating component 30, and the restoring force of the elastic component 50 causes the connecting component 40 to move inward toward the mounting plate 20, so that the first part 41 and the mounting plate 20 together clamp the open section 210. Here, the operating component 30 and the connecting component 40 move along... Figure 4 The arrow in the image moves back and forth in the direction it points.
[0053] In some embodiments, the operating member 30 may be integrally formed with the connector 40, or it may be independently installed on the connector 40.
[0054] In some embodiments, the operating member 30 has one or more abutment plates 32, preferably two abutment plates 32 arranged vertically spaced apart. When the operator's fingers are inserted into the operating hole 31, they come into contact with the abutment plates 32, thereby facilitating the operation of the operating member 30.
[0055] In some embodiments, the through groove 21 has an opening that faces upward or downward.
[0056] In some embodiments, the through groove 21 may be open at the top, and during assembly, the third part 43 and / or the fourth part 44 of the connector 40 are inserted into the through groove 21 from top to bottom. Preferably, a limiting plate may be set up above the connector 40.
[0057] In some embodiments, the through groove 21 may be a bottom opening, and during assembly, the third part 43 and / or the fourth part 44 of the connector 40 are inserted into the through groove 21 from bottom to top. Preferably, a limiting plate may be installed below the connector 40.
[0058] In some embodiments, the through groove 21 may be without an opening at the top or bottom, and there may be only the through groove 21. During assembly, the connector 40 is set to be spliced, and the third part 43 passes through the through groove 21 to splice the first part 41 and / or the second part 42, or the third part 43 itself is designed as two splicable parts.
[0059] In some embodiments, the first portion 41 and the second portion 42 are distributed facing each other on both sides of the mounting plate 20; in other embodiments, the first portion 41 and the second portion 42 are distributed offset on both sides of the mounting plate 20.
[0060] In some embodiments, the second part 42 can be divided into two regions, the third part 43 connects the first region of the first part 41 and the second region of the second part 42, and the fourth part 44 connects the second region of the first part 41 and the second region of the second part 42. The open port 441 is no longer provided. In this case, the guide wire 200 passes directly through the guide wire receiving space between the first part 41 and the mounting plate 20, instead of being inserted laterally. The two regions of the first part 41 and the second part 42 are either directly opposite or staggered, or one region is directly opposite the other and staggered. For example, the connector 40 is in a "U" shape.
[0061] In some embodiments, the top of the housing 10 is provided with a plurality of first limiting grooves 11, which are arranged at intervals along the extending direction of the housing 10. Each first limiting groove 11 is used to place a disc-shaped guide wire 200. In this embodiment, the number of first limiting grooves 11 is 10, that is, the guide wire feeding fixture 100 can accommodate 10 pieces of products, and can be customized according to customer needs.
[0062] In some embodiments, the front side of the mounting plate 20 is provided with at least one second limiting groove 23, each second limiting groove 23 being located below a clamping assembly. The second limiting groove 23 is used for the open segment 210 to pass through, thereby limiting the open segment 210 when it passes between the first portion 41 and the mounting plate 20.
[0063] In some embodiments, the box 10 of the wire feeding fixture 100 has handles on both sides, which facilitates the handling of the wire feeding fixture 100.
[0064] Figure 6 This is a schematic structural diagram of the baffle 12 according to an embodiment of the present invention. Figure 6 As shown, in some embodiments, the interior of the housing 10 is provided with a plurality of vertically arranged baffles 12, which are spaced apart along the extending direction of the housing 10. Each baffle 12 corresponds to a first limiting groove 11 for limiting the disc-shaped guide wire 200. This embodiment adds baffles 12 inside the housing 10 to limit the disc-shaped guide wire 200 and prevent the disc-shaped guide wire 200 placed in the first limiting groove 11 from tilting or shaking.
[0065] The wire feeding fixture 100 provided in this embodiment is relatively simple to operate and can achieve rapid feeding. Compared with the traditional feeding method, the feeding speed is increased by about 1 times. In addition, the entire wire feeding fixture 100 is relatively lightweight and can be easily loaded and unloaded by both men and women.
[0066] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
