背景技术Background technique
目前覆膜支架一般装入鞘管，随着鞘管移动至人体病变部分。覆膜支架装入鞘管的过程或者覆膜支架在鞘管内部移动的过程，覆膜支架与鞘管之间会存在摩擦力。而传统的鞘管，一般由弹簧螺旋延伸形成。覆膜支架与鞘管之间的摩擦力会使得覆膜支架沿着弹簧螺旋延伸方向转动，覆膜支架在人体的位置与预设的位置不同而容易导致手术失败。At present, the covered stent is generally loaded into the sheath, and moves to the diseased part of the human body along with the sheath. During the process of loading the stent-graft into the sheath or the process of moving the stent-graft inside the sheath, there will be friction between the stent-graft and the sheath. The traditional sheath tube is generally formed by the helical extension of a spring. The frictional force between the stent-graft and the sheath will cause the stent-graft to rotate along the helical extension direction of the spring, and the position of the stent-graft on the human body is different from the preset position, which easily leads to operation failure.
发明内容Contents of the invention

外管组件用于收容植入物，外管组件包括第一部分和与第一部分连接的第二部分，植入物滑过第一部分转动第一角度，植入物滑过第二部分转动第二角度，植入物滑过第一部分及第二部分后，植入物的姿态与预设姿态保持一致，其中，第一角度的方向和第二角度的方向相反。The outer tube assembly is used to accommodate the implant. The outer tube assembly includes a first part and a second part connected to the first part. The implant slides through the first part to rotate a first angle, and the implant slides through the second part to rotate a second angle. After the implant slides through the first part and the second part, the posture of the implant remains consistent with the preset posture, wherein the direction of the first angle is opposite to the direction of the second angle.
植入物滑过第一部分后会转动第一角度，植入物与预设姿态不同，植入物与预设姿态相差第一角度；植入物滑过第二部分并完全释放会转动第二角度。植入物在人体释放的姿态与预设姿态保持一致。避免植入物与预设姿态不同，植入物无法正常植入人体而导致手术失败。After the implant slides over the first part, it will rotate a first angle, and the implant is different from the preset posture, and the implant is different from the preset posture by a first angle; the implant slides through the second part and is fully released, and it will rotate a second time. angle. The released posture of the implant in the human body is consistent with the preset posture. To prevent the implant from being different from the preset posture, the implant cannot be implanted into the human body normally, resulting in the failure of the operation.

请参阅图1，本实施例提供一种外管组件1。外管组件1具有近端1A和与近端1A相对的远端1B。外管组件1用于收容植入物。植入物不限于为覆膜支架、封堵器等。植入物收容在外管组件1内。具体地，植入物收容在外管组件1的远端1B。本实施例以植入物为覆膜支架为例进行说明。Please refer to FIG. 1 , this embodiment provides an outer tube assembly 1 . The outer tube assembly 1 has a proximal end 1A and a distal end 1B opposite the proximal end 1A. The outer tube assembly 1 is used to accommodate implants. Implants are not limited to stent grafts, occluders, and the like. The implant is accommodated in the outer tube assembly 1 . Specifically, the implant is housed at the distal end 1B of the outer tube assembly 1 . In this embodiment, the implant is a stent-graft as an example for illustration.
覆膜支架从外管组件1的近端1A滑至外管组件1的远端1B，覆膜支架在外管组件1远端1B的姿态与覆膜支架装载进外管组件1之前的姿态（以下简称“预设姿态”）保持一致。在本实施例中，外管组件1包括第一部分11和与第一部分11相连的第二部分12。覆膜支架滑过第二部分12、第一部分11并从远端1B完全释放后，覆膜支架的姿态与预设姿态保持一致。具体地，在本实施例中，覆膜支架滑过第一部分11后会转动第一角度，覆膜支架与预设姿态不同，覆膜支架与预设姿态相差第一角度；覆膜支架滑过第二部分12并完全释放会转动第二角度。The stent-graft slides from the proximal end 1A of the outer tube assembly 1 to the distal end 1B of the outer tube assembly 1, and the posture of the stent-graft at the distal end 1B of the outer tube assembly 1 is the same as the posture before the stent-graft is loaded into the outer tube assembly 1 (hereinafter referred to as "preset posture") to be consistent. In this embodiment, the outer tube assembly 1 includes a first part 11 and a second part 12 connected to the first part 11 . After the stent-graft slides through the second part 12 and the first part 11 and is completely released from the distal end 1B, the posture of the stent-graft remains consistent with the preset posture. Specifically, in this embodiment, the stent-graft will rotate by a first angle after sliding through the first part 11, the stent-graft is different from the preset posture, and the stent-graft is different from the preset posture by the first angle; the stent-graft slides over The second part 12 and fully released will rotate the second angle.
覆膜支架完全释放后的姿态与预设姿态保持一致指的是，覆膜支架完全释放后的姿态，与预设姿态完全相同；或者，覆膜支架完全释放后的姿态，与预设姿态的偏差在预设范围内，且在该预设范围内，不影响医生的手术。在本实施例中，预设范围为负45°到正45°之间的区间。在其他实施例中，预设范围为负5°到5°之间的区间。The posture after the stent-graft is fully released is consistent with the preset posture means that the posture after the stent-graft is fully released is exactly the same as the preset posture; or, the posture after the stent-graft is fully released is the same as the preset posture. The deviation is within the preset range, and within the preset range, the doctor's operation will not be affected. In this embodiment, the preset range is an interval between minus 45° and plus 45°. In other embodiments, the preset range is an interval between negative 5° and 5°.
在本实施例中，第二角度的方向，与第一角度的方向相反。第二角度的大小与第一角度的大小相同；或者第二角度的大小与第一角度的大小接近相同，以覆膜支架转动第一角度、第二角度后，与预设姿态保持一致，且不影响医生的手术为准。In this embodiment, the direction of the second angle is opposite to the direction of the first angle. The size of the second angle is the same as the size of the first angle; or the size of the second angle is nearly the same as the size of the first angle, and after the stent graft rotates the first angle and the second angle, it remains consistent with the preset posture, and Does not affect the doctor's surgery shall prevail.
第二角度的大小与第一角度大小相等，方向相反。即，覆膜支架以预设姿态装入外管组件1的近端1A，从外管组件1的近端1A滑至外管组件1的远端1B、再从外管组件1的远端1B释放到人体，覆膜支架的每一部分都在第二部分上转动第二角度、再在第一部分上转动第一角度，覆膜支架在人体释放的姿态与预设姿态保持一致。避免覆膜支架与预设姿态不同，覆膜支架无法正常植入人体而导致手术失败。可以理解地，预设姿态可根据医生操作的习惯来调整，以覆膜支架释放到人体的姿态与预设姿态保持一致为准。The magnitude of the second angle is equal to that of the first angle, and the direction is opposite. That is, the stent-graft is loaded into the proximal end 1A of the outer tube assembly 1 in a preset posture, slides from the proximal end 1A of the outer tube assembly 1 to the distal end 1B of the outer tube assembly 1, and then slides from the distal end 1B of the outer tube assembly 1. After being released to the human body, each part of the stent-graft is rotated by a second angle on the second part, and then rotated by a first angle on the first part, and the released posture of the stent-graft on the human body remains consistent with the preset posture. Avoid the difference between the stent graft and the preset posture, and the stent graft cannot be implanted into the human body normally, resulting in operation failure. It can be understood that the preset posture can be adjusted according to the doctor's operating habits, and the posture when the stent-graft is released to the human body is consistent with the preset posture.
可以理解地，覆膜支架滑至外管组件1的远端时，靠近第二部分12的部分覆膜支架由于并没有滑过第一部分11，仍没有修正为预设姿态；但覆膜支架逐渐从外管组件1中释放到人体的过程，该部分会完全滑过第一部分11，并修正成预设姿态，然后再释放到人体。It can be understood that when the stent-graft slides to the distal end of the outer tube assembly 1, the part of the stent-graft close to the second part 12 has not been corrected to the preset posture because it has not slid over the first part 11; but the stent-graft gradually In the process of being released from the outer tube assembly 1 to the human body, the part will completely slide over the first part 11 and be corrected to a preset posture before being released to the human body.
在本实施例中，第一部分11在轴向方向上的长度、第二部分12在轴向方向上的长度均比覆膜支架要长。In this embodiment, the length of the first part 11 in the axial direction and the length of the second part 12 in the axial direction are both longer than the stent-graft.
在本实施例中，第一部分11由第一弹性部件111螺旋延伸形成。相同地，第二部分12由第二弹性部件螺旋延伸形成。第一弹性部件111、第二弹性部件均为具有弹性的部件。在本实施例中，第一弹性部件111、第二弹性部件均为弹簧。弹簧可提高整体外管组件1的抗弯折性能。在本实施例中，第一部分11由第一弹簧螺旋延伸形成。第二部分12由第二弹簧螺旋延伸形成。第一弹簧包括多个相连的第一弹簧圈，第二弹簧包括多个相连的第二弹簧圈。可以理解地，第一弹簧圈及第二弹簧圈不限于为金属，也可以为非金属、合金等材料制成。In this embodiment, the first portion 11 is formed by helically extending the first elastic member 111 . Similarly, the second portion 12 is formed by helically extending the second elastic member. Both the first elastic component 111 and the second elastic component are elastic components. In this embodiment, both the first elastic member 111 and the second elastic member are springs. The spring can improve the bending resistance of the overall outer tube assembly 1 . In this embodiment, the first part 11 is formed by the helical extension of the first spring. The second part 12 is formed by a second spring helical extension. The first spring includes a plurality of connected first coils, and the second spring includes a plurality of connected second coils. It can be understood that the first spring ring and the second spring ring are not limited to be made of metal, and can also be made of non-metal, alloy and other materials.
在本实施例中，第一部分11螺旋延伸的方向为右螺旋。第二部分12螺旋延伸的方向为左螺旋。具体地，第一弹簧的螺旋方向为右螺旋，第二弹簧的螺旋方向为左螺旋。在另一实施例中，第一弹簧的螺旋方向也可以为左螺旋，第二弹簧的螺旋方向也可以为右螺旋。In this embodiment, the helical extension direction of the first part 11 is a right helix. The direction in which the second part 12 extends helically is left helical. Specifically, the helical direction of the first spring is right helical, and the helical direction of the second spring is left helical. In another embodiment, the helical direction of the first spring may also be left helical, and the helical direction of the second spring may also be right helical.
可以理解地，除了螺旋延伸的方向，第一部分11与第二部分12的其他特性相同，以覆膜支架在第一部分11转动的角度大小，和在第二部分12转动的角度大小相等为准。即第二角度的大小，与第一角度的大小相等。具体地，第一部分11在轴向方向上的长度，和第二部分12在轴向方向上的长度相同。请参阅图1，在本实施例中，外管组件1的轴心方向与X轴的方向平行。第一部分11的螺距，与第二部分12的螺距相同。第一部分11中弹簧的直径与第二部分12中弹簧的直径相等。It can be understood that, except for the direction of helical extension, other characteristics of the first part 11 and the second part 12 are the same. That is, the magnitude of the second angle is equal to the magnitude of the first angle. Specifically, the length of the first portion 11 in the axial direction is the same as the length of the second portion 12 in the axial direction. Please refer to FIG. 1 , in this embodiment, the axis direction of the outer tube assembly 1 is parallel to the direction of the X axis. The pitch of the first part 11 is the same as that of the second part 12 . The diameter of the spring in the first part 11 is equal to the diameter of the spring in the second part 12 .
在其他实施例中，上述特性中的一个或者多个可不同，以覆膜支架在第一部分11转动的角度大小，和在第二部分12转动的角度大小相等为准。具体地，例如，第一部分11的螺距小于第二部分12的螺距；第一部分11在轴向的长度，大于第二部分12在轴向的长度，但支架在第一部分11中转动的角度大小，和在第二部分12中转动的角度大小相同。In other embodiments, one or more of the above characteristics may be different, and the angle at which the stent-graft rotates at the first part 11 is equal to the angle at which the second part 12 rotates. Specifically, for example, the pitch of the first part 11 is smaller than the pitch of the second part 12; the length of the first part 11 in the axial direction is greater than the length of the second part 12 in the axial direction, but the angle of rotation of the bracket in the first part 11 is It is the same as the angle of rotation in the second part 12 .
在本实施例中，第一部分11的长度与第二部分12的长度相同。具体地，在本实施例中，第一部分11在轴向方向的长度、及第二部分12在轴向方向的长度，均为外管组件1在轴向方向上长度的一半。第一部分11在轴向方向的长度、第二部分12在轴向方向的长度均大于覆膜支架在轴向方向上的长度。In this embodiment, the length of the first part 11 is the same as that of the second part 12 . Specifically, in this embodiment, the length of the first part 11 in the axial direction and the length of the second part 12 in the axial direction are both half of the length of the outer tube assembly 1 in the axial direction. Both the length of the first part 11 in the axial direction and the length of the second part 12 in the axial direction are greater than the length of the stent-graft in the axial direction.
请参阅图2，外管组件1还包括外层1C。外层1C覆膜覆盖第一部分11的外壁及第二部分12的外壁。外管组件1还包括内层1D，内层1D与外层1C相对设置。内层1D覆盖第一部分11的内壁及第二部分12的内壁。第一部分11及及第二部分12设置在外层1C和内层1D之间。外层1C及内层1D相互配合，将第一部分11及第二部分12固定，防止第一部分11及第二部分12相互脱离。外层1C的材料不限于为高分子材料。具体地，在本实施例中，外层1C由聚醚嵌段聚酰胺材料（PEBAX）制成，使外管组件1具备弹性，且耐磨的性能。内层1D不限于为高分子材料。具体地，在本实施例中，由聚四氟乙烯（Poly tetra fluoroethylene，PTFE）制成。内层1D表面光滑，能够减少支架与内层1D的摩擦力。在本实施例中，部分外层1C及部分内层1D填充第一部分11中多个第一弹簧圈之间的空隙、第二部分12中多个第二弹簧圈之间的空隙，使得第一部分11、第二部分12、内层1D及外层1C之间更加紧凑。具体地，在本实施例中，外层1C、内层1D通过热熔固定在一起，并将第一部分11及第二部分12固定。可以理解地，在其他实施例中，外层1C、内层1D不限于用热熔等其他方式来固定，也可以用粘接的方式固定。Please refer to FIG. 2 , the outer tube assembly 1 further includes an outer layer 1C. The coating of the outer layer 1C covers the outer wall of the first part 11 and the outer wall of the second part 12 . The outer tube assembly 1 also includes an inner layer 1D, which is arranged opposite to the outer layer 1C. The inner layer 1D covers the inner wall of the first part 11 and the inner wall of the second part 12 . The first part 11 and the second part 12 are disposed between the outer layer 1C and the inner layer 1D. The outer layer 1C and the inner layer 1D cooperate with each other to fix the first part 11 and the second part 12 and prevent the first part 11 and the second part 12 from being separated from each other. The material of the outer layer 1C is not limited to polymer materials. Specifically, in this embodiment, the outer layer 1C is made of polyether block polyamide material (PEBAX), so that the outer tube assembly 1 is elastic and wear-resistant. The inner layer 1D is not limited to polymer materials. Specifically, in this embodiment, it is made of polytetrafluoroethylene (Poly tetrafluoroethylene, PTFE). The surface of the inner layer 1D is smooth, which can reduce the friction between the bracket and the inner layer 1D. In this embodiment, part of the outer layer 1C and part of the inner layer 1D fill the gaps between the multiple first coils in the first part 11 and the gaps between the multiple second coils in the second part 12, so that the first part 11. The second part 12, the inner layer 1D and the outer layer 1C are more compact. Specifically, in this embodiment, the outer layer 1C and the inner layer 1D are fixed together by thermal fusion, and fix the first part 11 and the second part 12 . It can be understood that, in other embodiments, the outer layer 1C and the inner layer 1D are not limited to being fixed by other methods such as hot melting, but can also be fixed by bonding.
请参阅图3，在本实施例中，第一部分11与第二部分12沿轴向排布。第一部分11具有第一端部112，第一端部112靠近第二部分12。第二部分12具有第二端部122，第二端部122靠近第一部分11。第一端部112与第二端部122连接，且第一端部112和第二端部122相互平齐。第一端部112和第二端部122相互平齐指的是，第一端部112与第二端部122平整地对接。具体地，第一端部112与外管组件1的轴向垂直，第二端部122与外管组件1的轴向垂直，使得第一端部112能够平整贴合在第二端部122上，便于覆膜支架平稳地从第二部分12平稳地滑至第一部分11。Please refer to FIG. 3 , in this embodiment, the first part 11 and the second part 12 are arranged along the axial direction. The first part 11 has a first end 112 which is close to the second part 12 . The second part 12 has a second end 122 which is close to the first part 11 . The first end portion 112 is connected to the second end portion 122 , and the first end portion 112 and the second end portion 122 are flush with each other. The first end portion 112 and the second end portion 122 are flush with each other, which means that the first end portion 112 and the second end portion 122 are flatly abutted. Specifically, the first end 112 is perpendicular to the axial direction of the outer tube assembly 1 , and the second end 122 is perpendicular to the axial direction of the outer tube assembly 1 , so that the first end 112 can fit flatly on the second end 122 , so that the stent graft can smoothly slide from the second part 12 to the first part 11 smoothly.
在另一实施例中，请参阅图4，第一端部112和第二端部122之间相互倾斜。使得第一端部112和第二端部122之间的连接处，存在较大的空隙14。该空隙14会降低第一部分11和第二部分12之间的抗折强度，同时会降低外管组件1在第一部分11和第二部分12之间区域的强度，且覆膜支架滑过该空隙14容易朝径向向外扩张，而卡在第一部分11和第二部分12之间。In another embodiment, please refer to FIG. 4 , the first end portion 112 and the second end portion 122 are inclined to each other. Therefore, there is a larger gap 14 at the joint between the first end portion 112 and the second end portion 122 . The gap 14 will reduce the flexural strength between the first part 11 and the second part 12, and at the same time reduce the strength of the outer tube assembly 1 in the region between the first part 11 and the second part 12, and the stent graft slides through the gap 14 is easy to expand outward in the radial direction and get stuck between the first part 11 and the second part 12 .

The transition portion 15 is a hollow ring structure. Two opposite ends of the transition portion 15 are attached to the first end portion 112 of the first portion 11 and the second end portion 122 of the second portion 12 respectively. The transition part 15 improves the flexural strength between the first part 11 and the second part 12 in the outer tube assembly 1, and improves the strength of the area between the first part 11 and the second part 12 of the outer tube assembly 1. The first part 11 and the second part The parts 12 are less likely to be bent; and the stent-graft can pass through the joint between the first end 112 and the second end 122 more smoothly.

The sum of the rotation angles of the two second sub-parts 123 is equal, the direction of the rotation angle of the stent-graft sliding through the plurality of first sub-parts, and the rotation angle of the stent-graft sliding through the plurality of second sub-parts 123 The opposite direction prevails.
在本实施例中，第一子部分113的数量和第二子部分123的数量相等，第一子部分113的长度与第二子部分123的长度相等。第一子部件113的数量和第二子部分123为偶数个，且大于等于2个。In this embodiment, the number of the first sub-section 113 is equal to the number of the second sub-section 123 , and the length of the first sub-section 113 is equal to the length of the second sub-section 123 .

On the one hand, the hardness of the push rod assembly 7 is greater than that of the outer pipe, and the push rod assembly 7 is inserted into the outer pipe (not shown in the figure), which can increase the strength of the outer pipe and make the outer pipe difficult to dent in the extrusion of human blood vessels . On the other hand, the push rod assembly 7 restricts the position of the stopper 61, so that the stopper 61 is not easy to shift in the radial direction under the action of the stent-graft 2, and the stopper 61 is in close contact with the outer wall of the stent-graft 2 to prevent the stent graft 2 from rotating when the proximal end of the outer tube 1A slides to the distal end.

第十八实施例Eighteenth embodiment
请参阅图37，本实施例提供一种覆膜支架2。覆膜支架2包括主体21和稳固件22。稳固件22设置在主体21的外壁上。稳固件22可与限位组件（图未示）连接，稳固件22受到限位组件6的限位作用而无法转动，使得整体覆膜支架2也无法转动。Referring to FIG. 37 , this embodiment provides a stent graft 2 . The stent graft 2 includes a main body 21 and a stabilizer 22 . The stabilizer 22 is disposed on the outer wall of the main body 21 . The stabilizer 22 can be connected with a limiting component (not shown in the figure), and the stabilizing component 22 cannot rotate due to the limiting action of the limiting component 6 , so that the whole stent graft 2 cannot rotate.
在本实施例中，所述稳固件22包括多个间隔设置的稳固部221。多个稳固部221设置在主体21的外壁。稳固部221为中空的环状结构。在图37中，多个稳固部221在主体21外壁上，排成平行的组。每组在同一水平线上。在同一个组的稳固部221沿X轴方向排布。限位组件穿过在同一个水平方向上的多个稳固部221，限位组件限制同一个水平方向上的多个稳固部221的位置。可以理解地，覆膜支架2在外管组件内滑动，覆膜支架2与外管组件存在摩擦力，覆膜支架2具有沿着外管组件内弹簧结构的延伸方向转动的趋势。由于多个稳固部221受到限位组件的限位，使得主体21及整个覆膜支架2的转动也受到限位组件的限位，防止主体21及整个覆膜支架2转动。In this embodiment, the stabilizing member 22 includes a plurality of stabilizing portions 221 arranged at intervals. A plurality of stabilizing portions 221 are disposed on the outer wall of the main body 21 . The stabilizing portion 221 is a hollow ring structure. In FIG. 37 , a plurality of stabilizing portions 221 are arranged in parallel groups on the outer wall of the main body 21 . Each group is on the same level. The stabilizing parts 221 in the same group are arranged along the X-axis direction. The limiting assembly passes through the multiple stabilizing portions 221 in the same horizontal direction, and the limiting assembly restricts the positions of the multiple stabilizing portions 221 in the same horizontal direction. It can be understood that the stent-graft 2 slides in the outer tube assembly, there is friction between the stent-graft 2 and the outer tube assembly, and the stent-graft 2 has a tendency to rotate along the extension direction of the inner spring structure of the outer tube assembly. Since the plurality of stabilizing parts 221 are limited by the limiting component, the rotation of the main body 21 and the entire stent-graft 2 is also limited by the limiting component, preventing the main body 21 and the entire stent-graft 2 from rotating.
在本实施例中，稳固部221呈圆环状。多个稳固部221形成相对的两组。限位组件的数量与多个稳固部221形成的排数相同。即，每个限位组件限制在同一水平线上的稳固部221。可以理解地，在其他实施例中，多个稳固部221形成多个分组，限位组件的数量也与多个分组的组数相同。通过增大稳固部221组数及限位组件的数量，提高限位组件对稳固部221及覆膜支架2的限位效果，使得整个覆膜支架2难以转动。在另一实施例中，多个稳固部221形成四个分组时，四个分组间隔排布，并且关于覆膜支架2的中心对称分步。In this embodiment, the stabilizing portion 221 is in the shape of a ring. The plurality of stabilizing parts 221 form two opposite groups. The number of limiting components is the same as the number of rows formed by the plurality of stabilizing parts 221 . That is, each limiting component limits the stabilizing portion 221 on the same horizontal line. It can be understood that, in other embodiments, multiple stabilizing parts 221 form multiple groups, and the number of limiting components is also the same as the number of groups of multiple groups. By increasing the number of groups of stabilizing parts 221 and the number of limiting components, the limiting effect of the limiting components on the stabilizing parts 221 and the stent graft 2 is improved, making it difficult for the entire stent graft 2 to rotate. In another embodiment, when the plurality of stabilizing parts 221 form four groups, the four groups are arranged at intervals, and are divided into steps symmetrically with respect to the center of the stent-graft 2 .
可以理解地，稳固件22及其稳固部221与主体21的外壁固定连接。稳固件22与主体21的外壁的固定方式不限于为热熔、粘接等方式。稳固件22不限于由金属或者非金属材料制成。在本实施例中，稳固件22有镍钛丝制成。It can be understood that the stabilizer 22 and its stabilizer portion 221 are fixedly connected to the outer wall of the main body 21 . The fixing method of the stabilizer 22 and the outer wall of the main body 21 is not limited to hot-melt, adhesive and other methods. The stabilizer 22 is not limited to be made of metal or non-metal material. In this embodiment, the stabilizer 22 is made of nickel-titanium wire.
在本实施例中，将覆膜支架2安装进入输送器的外管组件的过程中，无论是将覆膜支架2装入外管组件的远端；还是，将覆膜支架2装入外管组件的近端，然后再将覆膜支架2从外管组件的近端滑至外管组件的远端，覆膜支架2的稳固件22都受到限位组件的限位作用而无法转动，保证了覆膜支架2在外管组件的远端的姿态与预设的姿态保持一致。In this embodiment, during the process of installing the stent graft 2 into the outer tube assembly of the conveyor, whether the stent graft 2 is loaded into the distal end of the outer tube assembly or the stent graft 2 is loaded into the outer tube the proximal end of the assembly, and then slide the stent graft 2 from the proximal end of the outer tube assembly to the distal end of the outer tube assembly, the stabilizer 22 of the stent graft 2 is limited by the limit assembly and cannot rotate, ensuring This ensures that the posture of the stent graft 2 at the distal end of the outer tube assembly is consistent with the preset posture.
