Description

Coil pipe
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to coil pipe.
Background
Aneurysms are common vascular diseases in clinic, and are mostly generated in the elderly, and the diseases easily cause rupture of the aortic aneurysm, thereby causing great threat to the life of patients.
With the continuous development of the existing medical technology, the covered stent is implanted into the body by utilizing a minimally invasive surgery, and the treatment surgery for treating aortic aneurysm and dissecting aneurysm is used, so that the covered stent is widely applied due to small wound and quick recovery. The treatment mode is that the covered stent is compressed into the conveying device, is guided into a human body along a guide wire track implanted in advance, reaches a diseased position, and then is released to isolate blood flow and the diseased position, and simultaneously rebuilds a blood flow channel, after the aneurysm and the interlayer lose blood flow supply, residual blood in a tumor cavity gradually forms thrombus and becomes blood vessel tissues, the tumor wall in an expanded state shrinks due to pressure, and the original state is gradually recovered, so that the purpose of treating the aneurysm and the interlayer is achieved.
However, the vascular structure of the human body is complicated, and when a lesion occurs at a branch site, a stent graft capable of reconstructing a branch artery is required. At present, one type of stent graft for such lesions is a built-in stent graft, i.e. a straight tube type stent graft is connected inside a straight tube stent graft, which is generally called an inner branch. When reconstructing a branch artery by using the covered stent, a guide wire track from a hole on the covered stent to the branch artery needs to be established.
However, the guide wire channel of the inner branch is difficult to establish in the operation process, in order to simplify the operation of the operation, the stent system can prepare the preset guide wire in the inner branch, the preset guide wire is caught by the catcher in the operation process and then pulled out, the guide wire channel penetrating through the inner branch can be established, the preset guide wire is preset in the conveyor, but the length of the preset guide wire is required to be far longer than that of the conveyor in the actual use process, so most of the preset guide wire is outside the body. The preformed guidewire can be compromised in its performance characteristics if any damage, such as kinking, or coating removal, occurs.
Generally, the guide wire is placed in a coil pipe to protect the guide wire from external influence, but for the preset guide wire preset in a conveyor, the coil pipe of the preset guide wire needs to be assembled with the conveyor as small as possible, the volume is reduced, and in order to ensure that the preset guide wire with the same length can be loaded, the coil pipe is required to be coiled as close to the circle center as possible. When the straight and elastic preset guide wire is fed into the coil, the closer to the circle center, the larger the friction force between the preset guide wire and the wall of the coil is, which can cause the problem that the preset guide wire cannot be arranged in the coil or the arranged preset guide wire is not easy to be drawn out.

Implementation mode one
Fig. 1 is a partial schematic structural diagram of a coil 100 according to a first embodiment of the present invention. Fig. 2 is a partial structural schematic view of the first bracket 20 in fig. 1. Referring to fig. 1 and 2, the coil 100 of the present embodiment includes a hollow coil body 10 and a first bracket 20, the first bracket 20 includes a first mounting surface 221 and a second mounting surface 222 that are oppositely disposed, the first mounting surface 221 and the second mounting surface 222 are respectively provided with a plurality of first mounting grooves 223, and the coil body 10 is clamped in the plurality of first mounting grooves 223, so that the coil body 10 is spirally disposed.
Specifically, the coil body 10 in the present embodiment is a deformable member, preferably a plastic member, which is easily bent and light in weight, and the coil body 10 is spirally engaged in the plurality of first mounting grooves 223. After the coil body 10 is fixed by the first bracket 20, the whole coil body is approximately circular or elliptical, so that the space occupancy rate of the coil body 10 can be reduced as much as possible. The first bracket 20 includes a middle section 21 and connecting sections 22 respectively provided at both ends of the middle section 21, and the connecting sections 22 at both ends respectively have a first mounting surface 221 and a second mounting surface 222.
When the coil pipe body 10 is connected with the first support 20, one embodiment is that the coil pipe body 10 penetrates from the first mounting groove 223 at the outermost side of the first mounting surface 221 and is coiled for multiple times along a spiral shape until the coil pipe body 10 is close to the first mounting groove 223 of the middle section 21, so that the coil pipe body 10 is fixed on the first mounting surface 221. And then, the rest part of the coil body 10 is continuously coiled along the first installation groove 223 of the second installation surface 222 close to the middle section 21 until the coil body 10 is coiled to the outermost first installation groove 223 of the second installation surface 222, so that the whole coil body 10 is fixed. In the process, the coil pipe 100 is in a double-layer structure because the coil pipe body 10 is coiled on the first mounting surface 221 and the second mounting surface 222. The benefit of bilayer structure lies in, compares to single-deck coil structure, in order to hold longer preset seal wire, the coil pipe must continue inside spiral and arrange, along with the diminishing of diameter, the length that each ring can hold is littleer and smaller, and along with the diminishing of diameter, the resilience of seal wire is bigger and bigger, results in the frictional force between coil pipe and seal wire bigger and bigger, leads to the seal wire can't insert in the coil pipe, perhaps can't take out from the coil pipe. The double-layer coil pipe 100 is coiled inwards in the radial direction by a certain size from one installation surface to the other installation surface after the coil pipe body 10 is coiled inwards in the radial direction, and is continuously coiled outwards in the radial direction, and the radial size is gradually increased, so that the friction force between the guide wire and the inner wall of the coil pipe body 10 is effectively reduced, the guide wire is convenient to be loaded into the coil pipe body 10, and the guide wire in the coil pipe body 10 is convenient to be drawn out.
Simultaneously, first support 20 plays the constraint effect to coil pipe body 10, because coil pipe body 10 and seal wire self have the resilience force, coil pipe body 10 after coiling can form circularly naturally, and through the constraint effect of first support 20, can reduce coil pipe body 10 by furthest and form oval to do benefit to coil pipe 100 and assemble in the less packing of size.
Fig. 3 is a partial structural view of the second bracket 30 in fig. 1. Referring to fig. 1 and 3, the coil pipe 100 in this embodiment further includes a second bracket 30, a plurality of second mounting grooves 31 are respectively disposed on two end surfaces of the second bracket 30, which are oppositely disposed, a portion of the coil pipe body 10 is clamped in the plurality of second mounting grooves 31, and positions and numbers of the plurality of second mounting grooves 31 are respectively corresponding to positions and numbers of the plurality of first mounting grooves 223.
Referring to fig. 1, 2 and 3, four first installation grooves 223 are respectively formed on the same installation surfaces of the connection ends 22 at the two ends, the wound coil body 10 forms a radial four-ring structure, and in order to ensure that the coil body 10 is orderly and orderly arranged in each ring, the number of the corresponding second installation grooves 31 is the same as that of the first installation grooves 223, and is four. In the present embodiment, the first mounting grooves 223 are provided only on both side surfaces of the first bracket 20, and thus the second mounting grooves 31 are also provided only on both opposite side surfaces of the second bracket 30.
The number of the first installation grooves 223 and the second installation grooves 31 depends on the number of the coiled circumference of the coil body 10, and when the number of the coiled circumference of the coil body 10 is large due to the overlong guide wire required to be stored in the coil body 10, the number of the first installation grooves 223 and the number of the second installation grooves 31 can be correspondingly increased, and similarly, the number of the first installation grooves 223 and the number of the second installation grooves 31 can also be correspondingly reduced. The bottom surfaces of the first mounting groove 223 and the second mounting groove 31 are arc-shaped surfaces, the radius of the arc-shaped surfaces is preferably equal to the radius of the coil body 10, and the arc length of the arc is slightly larger than half of the peripheral circumference of the cross section of the coil body 10, so that the first support 20 can keep stable after the coil body 10 is coiled into a spiral shape, and cannot be easily loosened. In other embodiments of the present invention, the radius of the arc shape of the bottom surfaces of the first mounting groove 223 and the second mounting groove 31 may be slightly larger or smaller than the radius of the coil body 10, as long as it is ensured that the coil body 10 is not easily loosened.
It can be understood that, in order to ensure the stability of the coiled pipe body 10, a corresponding number of the first support 20 and the second support 30 can be disposed on the coiled pipe body 10 according to actual requirements, and the present invention does not limit the specific number and the usage position of the first support 20 and the second support 30.
Fig. 4 is a schematic cross-sectional view of the coil 100 after receiving the guide wire 200 according to an embodiment of the present invention. As shown in fig. 4, in some embodiments of the present invention, the coil body 10 is a hollow tube, and a linear partition 40 connected to an inner wall of the hollow tube is disposed in the lumen of the coil body 10, so that the lumen of the coil body 10 is divided into two lumens which are not communicated with each other by the linear partition 40.
By arranging the partition plate 40 in the lumen and dividing the lumen into two lumens different from each other, on the one hand, one guide wire 200 can be respectively accommodated in the two lumens, thereby increasing the storage number of the guide wires 200 without additionally adding the coil pipe 100. On the other hand, when the storage space of the coil body 10 is not enough, the guide wire 200 may be continuously inserted along one lumen of the coil body 10 after the other lumen is full, so as to further increase the length of the coil 100 for storing the guide wire 200.
The outer profile of the coil body 10 can have various forms, preferably circular. The circular outer profile can be easily fixed in the first mounting groove 223, thereby facilitating the assembly of the coil body 10. The partition plate 40 has various arrangement forms, the linear partition plate 40 has a simple structure, the flexibility of the coil pipe 100 is not influenced, the contact area of the guide wire 200 and the partition plate 40 in the coil pipe body 10 is the minimum, and the friction force can be well reduced. The wall thickness of the coil body 10 and the wall thickness of the partition 40 are preferably 0.2-0.5mm, too small a wall thickness is prone to rupture, too large a wall thickness affects the flexibility of the coil body 10 and is prone to break during bending.
Fig. 5 is a schematic cross-sectional view of a coil 100 after receiving a guide wire 200 according to another embodiment of the present invention. As shown in fig. 5, in this embodiment, the outer contour of the coil body 10 is circular, and the partition 40 is S-shaped.
Fig. 6 is a schematic cross-sectional view of a coil 100 after receiving a guide wire 200 according to another embodiment of the present invention. As shown in fig. 6, the coil body 10 in this embodiment has a circular outer contour, and the separator 40 has an hourglass shape.
Fig. 7 is a schematic cross-sectional view of a coil 100 after receiving a guide wire 200 according to another embodiment of the present invention. As shown in fig. 7, in this embodiment, the coil body 10 has a circular outer contour, and the inside of the tube cavity is divided into three tube cavities that are not communicated with each other by the partition plates 40 arranged in a herringbone manner.
Fig. 8 is a schematic cross-sectional view of a coil 100 after receiving a guide wire 200 according to another embodiment of the present invention. As shown in fig. 8, in this embodiment, the outer contour of the coil body 10 is elliptical, and the partition 40 is linear.
Second embodiment
Fig. 9 is a partial schematic structural view of the first bracket 20 according to the second embodiment of the present invention. As shown in fig. 9, the present embodiment is substantially the same as the first embodiment, except that two first mounting grooves 223 are also provided in the end surface 224 of the connecting section 22 of the first bracket 20 between the first mounting surface 221 and the second mounting surface 222 in the present embodiment.
When the coil body 10 is coiled, in one embodiment, the coil body 10 is coiled from the first mounting surface 221 near the first mounting groove 223 of the intermediate section 21, and when the coil is coiled to the outermost first mounting groove 223 of the connection section 22, the coil of the coil body 10 on the first mounting surface 221 is completed. And then, according to the position shown in fig. 9, the coil is coiled from the first installation groove 223 above the end surface 224 to the first installation groove 223 below the end surface 224, and then the coil is coiled continuously from the outermost first installation groove 223 of the second installation surface 222 until the first installation groove 223 close to the middle section 21 is reached, so that the coiling process of the coil body 10 is completed, and the coil body 10 is in a four-layer structure. If the number of layers of the coiled pipe body 10 is further increased, the number of the first installation grooves 223 on the end surface 224 can be correspondingly increased.
Fig. 10 is a partial structural schematic view of the second bracket 30 according to the second embodiment of the present invention. Correspondingly, in the second bracket 30 of the present embodiment, in addition to the plurality of second mounting grooves 31 respectively provided on the two end surfaces arranged in opposite directions, two second mounting grooves 31 are also provided on one side end surface of the second bracket 30, so that the coil body 10 is coiled orderly under the cooperation of the first bracket 20 and the second bracket 30.
Third embodiment
Fig. 11 is a partial schematic structural view of the coil pipe 100 according to the third embodiment of the present invention after the guide wire 200 is housed therein. As shown in fig. 11, the coil 100 of the present embodiment includes a plurality of coil bodies 10 and a plurality of first brackets 20, and the radial dimensions of the plurality of coil bodies 10 may be equal or different. Each coil pipe body 10 is clamped in the first installation grooves 223 of the two first brackets 20. Each coil body 10 comprises two C-shaped sub-coils 11 with opposite openings and arranged at a distance. The two ends of the sub-coil pipe 11 are respectively clamped in a first mounting groove 223 of the first bracket 20, and the openings of the two C-shaped sub-coil pipes 11 are oppositely arranged. A guidewire 200 is threaded into the lumen of each coil body 10 and a portion of the guidewire 200 is exposed at a location spaced between the two sub-coils 11 of the coil body 10.
Specifically, the coil 100 may be circular or elliptical in its entirety. The coil 100 may house one or more guide wires 200. Taking the example of accommodating a plurality of guide wires 200, each of the plurality of guide wires 200 is inserted into one coil body 10, and each guide wire 200 is partially exposed between two sub-coils 11 of the corresponding coil body 10. For example, the oval portion of the outermost layer in fig. 11, two parallel straight line segments between the two sub-coils 11 are part of the exposed guide wire 200. The advantage of this design is that when the guide wire 200 is pulled out and is stressed, the stress direction of the guide wire 200 and the pull-out path of the guide wire 200 are the same, and the guide wire 200 is not deformed due to the pulling-out. The interval part between two sub-coils 11 of the same coil body 10 can reduce the friction between the coil body 10 and the guide wire 200, and is also favorable for switching the guide wire 200 between coil bodies 10 at different radial positions. The larger the distance between the two sub-coil pipes 11 of the same coil pipe body 10 is, that is, the longer the exposed length of the guide wire 200 is, the larger the distance between the first support 20 connected with one of the sub-coil pipes 11 in a clamping manner and the other first support 20 connected with the other sub-coil pipe 11 in a clamping manner is.
The coiled tubing 100 may be a two or more layer structure or a single layer structure with the separator 40 disposed within the lumen, in the same manner as the coiled tubing of the first embodiment, thereby increasing the overall length of the coiled tubing 100. Further, since the two sub-coils 11 constituting the coil body 10 are not physically continuous in the present embodiment, the number of the first brackets 20 in the present embodiment is two, and the two first brackets 20 are arranged in parallel, wherein the plurality of first installation grooves 223 on one first bracket 20 are respectively arranged opposite to the plurality of first installation grooves 223 on the other first bracket 20 in pairs. Further, the two first brackets 20 can be connected by a connecting rod 50, so as to connect and fix a plurality of coil bodies 10. The larger the length of the connecting rod 50 is, the larger the distance between the two first brackets 20 is, and thus the longer the straight line segment of the guide wire 200 exposed outside is, the greater the friction force between the coil body 10 and the guide wire 200 can be reduced, so that the guide wire 200 can be more easily drawn in the coil body 10.
In other embodiments, the coiled tubing body 10 can be snapped onto more than two first brackets 20. The two first brackets 20 can also be connected through two or more connecting rods 50 to enhance the connection firmness and avoid the overall deformation of the coil pipe 100 caused by the local stress of the coil pipe body 10.
In other embodiments, such as the coil 100 shown in fig. 11, the middle section of the C-shaped sub-coil 11 may be broken, that is, the C-shaped sub-coil 11 may only retain a portion of the first bracket 20, that is, only retain portions near two ends of the C-shaped sub-coil 11. Further, the two sub-coils 11 located at the outermost position may be left in a C shape to avoid the guide wire 200 located at the outermost position from being damaged, and to avoid the end of the sub-coil 11 from being easily scratched due to the large friction between the end of the sub-coil 11 and the guide wire 200 bent at the position when the guide wire 200 is withdrawn.
Referring to fig. 4 and 11, the coil 100 of the present invention is used to accommodate one or more guide wires 200 disposed in the lumen of the coil body 10, and may also be used to accommodate other linear members similar to the guide wires 200.
Compared with a single-layer coil structure, the coil 100 of the present embodiment can accommodate a longer or greater number of guide wires 200, and effectively reduce the friction between the guide wires 200 and the inner wall of the coil body 10, so as to facilitate the installation of the guide wires 200 into the coil body 10, and the extraction of the guide wires 200 from the coil body 10.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
