[0030] Referring to Figures 1 to 7 , in an embodiment of the present utility model, a wire guide includes:
[0031] The needle part 100 includes a needle rod body 110 and a blocking ring 120 arranged on the outer periphery of one end of the needle rod body 110 in the length direction. A threading channel 111 in the form of a blind hole is arranged on the needle rod body 110 and extends from the end surface of one end in the length direction to the other end. An outlet hole 112 leading to the threading channel 111 is arranged on the side wall of the other end of the needle rod body 110 in the length direction.
[0032] The handle part 200 includes a front-end solid 210, a middle-section plate 220, and a rear-end solid 230 that are sequentially connected to enclose a handle opening 240. A first channel 211 and a second channel 231 that are aligned with each other are respectively penetrated through the front-end solid 210 and the rear-end solid 230 in the length direction. Both the first channel 211 and the second channel 231 lead to the handle opening 240. Among them, the needle part 100 passes through the second channel 231 and penetrates into the first channel 211, and the first channel 211 matches the needle rod body 110 and blocks the blocking ring 120.
[0033] Among them, the inner diameter of the second channel 231 is larger than the outer diameter of the needle part 100.
[0034] In the prior art, the introducer includes a needle part and a needle holder part that are connected to each other, generally made of stainless steel. Due to certain dead corners in the connection part, there is a problem of incomplete disinfection during the disinfection process; in particular, during the use of the wire introducer, the wire introducer can guide the user to perform relevant operations or adjustments by receiving force feedback. However, due to the existence of the needle holder part, the action received by the needle part cannot be sensitively and directly perceived by the user, and thus the fineness of the operation process is poor.
[0035] In the present utility model, the wire introducer includes a needle part 100 and a handle part 200. The needle part 100 completes the penetration and withdrawal actions, and the handle part 200 serves as the basis for holding by hand.
[0036] The needle part 100 includes a needle rod body 110 and a blocking ring 120 arranged at one end of the needle rod body 110 in the length direction. A threading channel 111 in the form of a blind hole is arranged on the needle rod body 110 and extends from the end surface of one end in the length direction to the other end. An outlet hole 112 leading to the threading channel 111 is arranged on the side wall of the other end of the needle rod body 110 in the length direction. The installation of the wire is realized through the threading channel 111 and the outlet hole 112 on the needle part 100.
[0037] The handle part 200 includes a front-end entity 210, a middle-section plate 220, and a rear-end entity 230 that are sequentially connected to enclose a handle opening 240. The handle opening 240 serves as the meshing and placement position for the thumb or index finger. The first channel 211 and the second channel 231 that are aligned with each other are respectively penetrated in the length direction of the front-end entity 210 and the rear-end entity 230, and both the first channel 211 and the second channel 231 communicate with the handle opening 240. The needle part 100 passes through the second channel 231 and penetrates into the first channel 211. The first channel 211 matches the needle rod body 110 and blocks and restricts the blocking ring 120. The inner diameter of the second channel 231 is larger than the outer diameter of the needle part 100, so as to ensure that the needle part 100 can be installed at the position of the rear-end entity 230 of the handle part 200. The cross-section of the first channel 211 can be unchanged or reduced, mainly for restricting the needle part 100. The cross-section of the needle rod body 110 is preferably circular or oval.
[0038] In summary, the structure between the needle part 100 and the handle part 200 is a dismountable structure, so that a better degree of disinfection can be achieved; the handle opening 240 on the handle part 200 can serve as the holding basis for the user, improving the operability of the entire wire guide; when the needle part 100 is combined with the front-end entity 210 of the handle part 200, the blocking ring 120 on the needle part 100 restricts the outward detachment of the needle part 100, and the size of the blocking ring 120 is larger than that of the needle part 100. When the needle part 100 abuts against the user's finger, it can directly give the user force feedback without causing discomfort or harm to the user.
[0039] Refer to Figure 3 , in one embodiment, a limiting groove 212 is provided at one end of the first channel 211 close to the second channel 231, and the shape of the limiting groove 212 corresponds to that of the blocking ring 120.
[0040] In this embodiment, considering that the needle part 100 of the wire guide is abutted by the user's finger during use, if the blocking ring 120 protrudes from the front-end entity 210, it is not convenient for the finger to abut; then a limiting groove 212 is provided on the first channel 211, and the shape of the limiting groove 212 corresponds to that of the blocking ring 120. After the needle part 100 is installed, the blocking ring 120 is flush with the front-end entity 210. The above flush setting makes the user more stable during the process of abutting the needle part 100.
[0041] Refer to Figures 4 to 7 , in one embodiment, the cross-section of the first channel 211 is oval, and the cross-section of the needle rod body 110 corresponds to the first channel 211 and is oval.
[0042] In this embodiment, by defining the shapes of the first channel 211 and the needle rod body 110, the shape matching formed between the needle rod body 110 and the front-end entity 210 of the handle part 200 can directly limit the rotation of the needle part 100, facilitating the use process of the wire guide. Specifically, the ratio of the major axis to the minor axis of the cross-section of the first channel 211 is designed and adjusted according to the processing and usage conditions.
[0043] In one embodiment, the length direction of the wire outlet hole 112 is consistent with the length direction of the cross-section of the needle rod body 110.
[0044] In this embodiment, the extending direction of the wire outlet hole 112 is set to be consistent with the length direction of the cross-section of the needle rod body 110, so that the length of the wire outlet hole 112 can be as long as possible, and a more sufficient chamfer structure can be formed. Through the above settings, the possibility that the pulling wire is damaged by the wire outlet hole 112 during the operation is reduced.
[0045] In one embodiment, the middle section plate 220 is provided with a concave arc on the side close to the handle opening 240.
[0046] In this embodiment, by providing an arc surface on the middle section plate 220, and the handle opening 240 is the position held by the user, the above arc surface setting makes the holding process more stable.
[0047] In one embodiment, the needle rod body 110 and the blocking ring 120 are of an integral structure.
[0048] In this embodiment, during the processing of the needle rod body 110, local processing is performed on one end of the needle rod body 110 in the length direction, so that the blocking ring 120 is processed. For example, after the cold rolling of the needle rod body 110 is completed, local heat treatment is performed on one end of the needle rod body 110 in the length direction, and then the blocking ring 120 is formed by pressing. The integral setting of the needle rod body 110 and the blocking ring 120 makes the overall structure more stable and reduces the risk of failure.
[0049] In one embodiment, the blocking ring 120 is made of a polymer material and is a connecting structure with the needle rod body 110.
[0050] In this embodiment, considering that the processing method of the needle rod body 110 is often cold rolling, it is difficult to process its end. At this time, the blocking ring 120 and the needle rod body 110 are set as a connecting structure, and the shape of the blocking ring 120 can be selectively improved. The connection method between the blocking ring 120 and the needle rod body 110 can be snap connection or bonding, etc., specifically based on achieving stable connection. The material of the blocking ring 120 is selected from at least one of polyvinyl chloride, polyethylene, polypropylene, polystyrene, polycarbonate, polyurethane, polyamide, polysulfone, and polyether ether ketone.
[0051] In one embodiment, the outer surface of the handle portion 200 is provided with anti-slip patterns.
[0052] In this embodiment, considering that the wire guide sometimes rotates during the withdrawal process, the anti-slip pattern can be a convex or concave stripe structure, a convex point structure, etc. of various shapes, and the size of the convex or concave can be 0.5 to 2 mm. At this time, the anti-slip pattern provided on the outer surface of the handle portion 200 can improve the convenience of operation.
[0053] In one embodiment, the needle rod body 110 and the handle portion 200 are made of stainless steel.
[0054] In this embodiment, the needle body 110 and the handle 200 are made of stainless steel, so that hygiene is guaranteed, especially stainless steel is adaptable to various methods of disinfection. Medical stainless steel usually refers to the addition of 18% chromium or 10% nickel to make the steel more durable and corrosion-resistant, with excellent use characteristics.
[0055] In one embodiment, a side of the middle plate 220 facing away from the handle opening 240 is provided with anti-slip grooves.
[0056] In this embodiment, considering that the back side of the middle plate 220 is more important for stable holding during the holding of the wire guide, an anti-slip pattern is provided on the side of the middle plate 220 away from the handle 240 to improve the use effect. The anti-slip pattern can be a convex or concave stripe structure, a convex point structure, etc. of various shapes, and the size of the convex or concave can be 0.5 to 2 mm.
[0057] In summary, the wire guide provided by the utility model has a disassembly structure between the needle portion 100 and the handle portion 200, so that the degree of disinfection can be better achieved; the handle opening 240 on the handle portion 200 can be used as a basis for the user to hold, so that the operability of the entire wire guide is improved; when the needle portion 100 is combined with the front end entity 210 of the handle portion 200, the blocking ring 120 on the needle portion 100 limits the needle portion 100 from falling out, and the size of the blocking ring 120 is larger than that of the needle portion 100. When the needle portion 100 is against the user's finger, it can directly give the user force feedback without causing discomfort or harm to the user.
[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
