Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically to a coil for packaging neurotransmitter wires. Background Technology

[0002] In neurointerventional surgery, a guidewire is a thin metal wire used to guide other instruments through blood vessels to the treatment site, while a coil is a device for storing and transporting the guidewire. It is usually a circular reel that can be easily deployed and retracted.

[0003] The coil can protect the internal neurosurgical guidewire. Traditional snap-fit ​​coils are molded in one piece, which is prone to deformation during use, resulting in product deformation. At the same time, the front and rear ends of the neurosurgical guidewire cannot be picked up by hand and can only be pulled out from the middle of the guidewire, which is inconvenient for medical staff to handle and thus inconvenient for medical staff to operate. Utility Model Content

[0004] The purpose of this utility model is to provide a coil for packaging neurotransmitter guidewires, in order to solve the problems mentioned in the background art. The coil can protect the internal neurotransmitter guidewires, but the traditional snap-fit ​​coil is integrally molded and is prone to deformation during use, which leads to product deformation. At the same time, the front and rear ends of the neurotransmitter guidewire cannot be picked up by hand and can only be pulled out from the middle of the guidewire, which is inconvenient for medical staff to handle and thus inconvenient for medical staff to operate.

[0005] This utility model provides the following technical solution: a coil for packaging a guide wire, comprising a guide wire body and a coil body; the outer side of the guide wire body is provided with a coil body, and a connecting structure is installed on the outer side of the coil body;

[0006] The connection structure includes a connector, a connecting ring, a locking block, and a locking groove. The outer sides of both ends of the coil body are provided with connecting rings, one end of the connecting ring is equipped with a connector, both ends of the connector are provided with locking blocks, and the inner side of the connecting ring near the connector is provided with a locking groove.

[0007] Preferably, the outer side of the connector is provided with a connecting buckle.

[0008] Preferably, the connecting buckle has a protrusion on the outer side near the connector, and the connector has a fixing groove on the inner side near the protrusion.

[0009] Preferably, the connector has a retaining ring inside.

[0010] Preferably, the outer surface of the connector and the connecting ring is provided with a protective layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a connector, a connecting ring, a locking block, and a locking groove in combination. The segmented coil body facilitates access for medical staff and improves the overall packaging strength. By locking the locking block at one end of the connector into the locking groove inside the connecting ring, the connector and the connecting ring at one end of the coil body can be spliced ​​together, thus allowing multiple coil bodies to be spliced ​​together. When medical staff move the connector and the connecting ring to separate them, the guidewire body can be directly pulled out from the middle, which facilitates the operation of medical staff.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0022] Example 1:

[0023] This application provides a coil for packaging a neurotransmitter guidewire, comprising a guidewire body 1 and a coil body 2; the outer side of the guidewire body 1 is provided with the coil body 2, and the outer side of the coil body 2 is equipped with a connecting structure 3;

[0024] The connection structure 3 includes a connector 301, a connecting ring 302, a locking block 303, and a locking groove 304. The outer sides of both ends of the coil body 2 are provided with a connecting ring 302, one end of the connecting ring 302 is equipped with a connector 301, both ends of the connector 301 are provided with locking blocks 303, and the inside of the connecting ring 302 near the connector 301 is provided with a locking groove 304.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the coil body 2 is used to protect the internal guidewire body 1, and the connecting structure 3 is used to splice multiple coil bodies 2. Multiple coil bodies 2 are set on the outside of the guidewire body 1. By locking the locking block 303 at one end of the connector 301 into the locking groove 304 inside the connecting ring 302, the connector 301 at one end of the coil body 2 can be spliced ​​with the connecting ring 302, so that multiple sets of coil bodies 2 can be spliced. When the medical staff moves the connector 301 and the connecting ring 302 to separate them, the guidewire body 1 can be directly pulled out from the middle, which facilitates the operation of the medical staff.

[0026] Furthermore, a connecting buckle 4 is provided on the outer side of the connector 301;

[0027] Specifically, such as Figure 3 As shown, in order to fix and store the coil body 2, the coil body 2 is wrapped around and locked inside the connecting buckle 4 on one side of the connector 301. The connecting buckle 4 can fix the coil body 2 and prevent it from falling apart and affecting storage.

[0028] Furthermore, the connecting buckle 4 has a protrusion 5 on the outer side near the connector 301, and the connector 301 has a fixing groove 6 on the inner side near the protrusion 5;

[0029] Specifically, such as Figure 3 As shown, in order to disassemble and install the connecting buckle 4, the connecting buckle 4 can be fixedly installed on the connector 301 by snapping the protrusion 5 of the connecting buckle 4 into the fixing groove 6. When the person moves the connecting buckle 4 and the protrusion 5 moves out of the fixing groove 6, the connecting buckle 4 can be removed.

[0030] Furthermore, a retaining ring 7 is provided inside the connector 301;

[0031] Specifically, such as Figure 1 As shown, in order to limit the internal guide wire body 1, the fixing ring 7 is set inside the connector 301. When the guide wire body 1 passes through the inside of the fixing ring 7, the fixing ring 7 can limit and fix the guide wire body 1.

[0032] Furthermore, a protective layer 8 is provided on the outer surface of the connector 301 and the connecting ring 302;

[0033] Specifically, such as Figure 4 As shown, in order to protect the outer side of the coil body 2, the protective layer 8 is composed of protective material. The protective layer 8 can protect the outer surface of the connector 301 and the connecting ring 302, and prevent damage to the connector 301 and the connecting ring 302.

[0034] Working principle: By locking the locking block 303 at one end of the connector 301 into the locking groove 304 inside the connecting ring 302, the connector 301 at one end of the coil body 2 can be spliced ​​with the connecting ring 302, thereby splicing multiple sets of coil bodies 2. The coil body 2 can protect the internal guide wire body 1.

[0035] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
