本实用新型涉及医疗器械领域，尤其涉及一种球囊扩张导管、弯球囊及其弯球囊的成型模具。The utility model relates to the field of medical equipment, in particular to a balloon expansion catheter, a curved balloon and a molding die for the curved balloon.
背景技术Background technique
血管内介入治疗是在不暴露病灶的情况下，通过在皮肤和血管上开通微小的通道，在影像设备的引导下进行创伤最小的治疗方法。经过30多年的不断发展，球囊扩张导管主要应用于经皮腔内血管成形术、血管支架、溶栓治疗等。球囊扩张导管需配合预先已经通入到体内病变位置的导丝一起使用。球囊导管在沿导丝的路径推至病变部位的过程中，需要具备良好的穿越弯曲血管和复杂病变血管的能力，这就要求球囊导管远端特别是球囊部分可以有效地接收施加于近端手柄上的推力并且可以很好地顺应血管的形状前进。此外，由于现今所有传统结构的球囊扩张导管都采用了等壁厚且表面平滑的球囊结构，在血管内扩张后，球囊内部各位置压强相等，球囊主体有效部位成圆柱体扩张。随着球囊的逐渐膨胀，会产生强直血管作用，也就是血管被支撑呈笔直的管体，而非血管本身呈现的自然弧形管体。在球囊保持压力的时间内，靶病变血管往往容易在外力的作用下改变原有形态而受到损伤，这给手术的成功率和术后恢复都带来了隐患。Endovascular interventional therapy is a minimally invasive treatment method under the guidance of imaging equipment by opening tiny channels on the skin and blood vessels without exposing the lesion. After more than 30 years of continuous development, balloon dilatation catheters are mainly used in percutaneous transluminal angioplasty, vascular stents, and thrombolytic therapy. Balloon dilatation catheters should be used together with a guide wire that has been passed into the lesion in the body in advance. When the balloon catheter is pushed along the path of the guide wire to the lesion, it needs to have a good ability to pass through curved blood vessels and complex diseased blood vessels, which requires that the distal end of the balloon catheter, especially the balloon part, can effectively receive the Push on the proximal handle and advances well to the shape of the vessel. In addition, since all the balloon dilatation catheters with traditional structures today adopt a balloon structure with equal wall thickness and smooth surface, after intravascular expansion, the pressure at each position inside the balloon is equal, and the effective part of the balloon body expands into a cylinder. With the gradual expansion of the balloon, there will be an ankylosing effect, that is, the blood vessel is supported as a straight tube body, rather than the natural curved tube body presented by the blood vessel itself. During the time when the balloon maintains pressure, the target lesion blood vessel is often easily damaged by changing its original shape under the action of external force, which brings hidden dangers to the success rate of the operation and postoperative recovery.

具体实施方式Detailed ways
为使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本实用新型进行详细描述。In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
本实用新型实施例提供一种应用在球囊扩张导管上的弯球囊，如图1所示，包括：The embodiment of the utility model provides a curved balloon applied on a balloon dilatation catheter, as shown in FIG. 1 , including:
呈圆筒状的弯球囊主体3，弯球囊主体3的外表面设置有多个径向凹槽纹路4。The curved balloon body 3 is cylindrical, and the outer surface of the curved balloon body 3 is provided with a plurality of radial grooves 4 .
通过在弯球囊主体3的外表面设置有多个径向凹槽纹路4，使得弯球囊在充压和保压过程中，任意一侧受外力成延展状态时，对侧就会相应的收紧，从而形成弧形，由此实现了弯球囊在不受操作者控制的情况下，可以顺应病变部位血管弯曲的弧度和方向自行弯曲。保障在输送支架10时可有效避免强直血管现象，可以顺应血管弯曲弧度将支架10植入在靶病变血管9中，保证了更好的贴壁效果，减轻了手术过程中支架10对血管的损伤。A plurality of radial grooves 4 are arranged on the outer surface of the curved balloon main body 3, so that during the inflation and pressure holding process of the curved balloon, when any side of the curved balloon is extended by external force, the opposite side will be correspondingly stretched. Tighten to form an arc, thereby realizing that the curved balloon can bend itself in accordance with the curvature and direction of the blood vessel in the diseased part without being controlled by the operator. It ensures that ankylosing blood vessels can be effectively avoided when the stent 10 is delivered, and the stent 10 can be implanted in the target diseased blood vessel 9 in compliance with the curvature of the blood vessel, ensuring a better wall-attachment effect and reducing the damage of the stent 10 to the blood vessel during the operation .
本实用新型上述实施例中，如图1所示，弯球囊包括：位于弯球囊主体3的两端，分别与弯球囊主体3连接的球囊远端锥体21和球囊近端锥体22；与球囊远端锥体21连接的球囊远端连接颈11；和与球囊近端锥体22连接的球囊近端连接颈12；其中，球囊远端连接颈11、球囊远端锥体21、弯球囊主体3、球囊近端锥体22和球囊近端连接颈12的轴心在同一条直线上。In the above-mentioned embodiment of the utility model, as shown in Figure 1, the curved balloon includes: the two ends of the curved balloon main body 3, the balloon distal cone 21 and the balloon proximal end respectively connected with the curved balloon main body 3 The cone 22; the balloon distal connection neck 11 connected with the balloon distal cone 21; and the balloon proximal connection neck 12 connected with the balloon proximal cone 22; wherein, the balloon distal connection neck 11 , the balloon distal cone 21 , the curved balloon main body 3 , the balloon proximal cone 22 and the balloon proximal connecting neck 12 are on the same straight line.
具体的，球囊远端连接颈11、球囊远端锥体21、弯球囊主体3、球囊近端锥体22和球囊近端连接颈12依次连接，组成弯球囊。且圆筒状的弯球囊主体3的直径大于球囊远端连接颈11和球囊近端连接颈12的直径。球囊远端锥体21和球囊近端锥体22与弯球囊主体3接触的端面的直径与弯球囊主体3的直径相等。球囊远端锥体21与球囊远端连接颈11接触的端面的直径与球囊远端连接颈11的直径相等，球囊近端锥体22与球囊近端连接颈12接触的端面的直径与球囊近端连接颈12的直径相等。Specifically, the balloon distal connection neck 11 , the balloon distal cone 21 , the curved balloon body 3 , the balloon proximal cone 22 and the balloon proximal connection neck 12 are sequentially connected to form a curved balloon. Moreover, the diameter of the cylindrical curved balloon body 3 is larger than the diameters of the connecting neck 11 at the distal end of the balloon and the connecting neck 12 at the proximal end of the balloon. The diameters of the end faces of the balloon distal cone 21 and the balloon proximal cone 22 in contact with the curved balloon body 3 are equal to the diameter of the curved balloon body 3 . The diameter of the end surface of the balloon distal cone 21 in contact with the balloon distal connection neck 11 is equal to the diameter of the balloon distal connection neck 11, and the end surface of the balloon proximal cone 22 in contact with the balloon proximal connection neck 12 The diameter of the balloon is equal to the diameter of the connecting neck 12 at the proximal end of the balloon.
在本实用新型上述实施例中，在未受外力的自然状态下，弯球囊主体3轴向上除凹槽纹路4外各个位置的外径均相等。若球囊主体3各位置受到的束缚力相等，弯球囊主体3轴向除凹槽纹路4外各位置的外径均保持相等。在手术过程中，操作者向球囊扩张导管中注入造影剂，弯球囊充压膨胀用来扩张因病变而变得狭窄的血管。弯球囊充盈的过程中，弯球囊直径逐渐扩大，弯球囊外壁或压装在弯球囊上的支架10会对血管内壁施加径向的支撑力，同时血管也会对弯球囊施加指向弯球囊内部的反作用力，也可称之为束缚力。若靶病变血管9无自然弯曲，则球囊主体3各位置受到的束缚力相等，弯球囊不会呈现弯曲形态。若靶病变血管9有自然弯曲，则球囊主体3各位置受到的束缚力不相等，弯球囊会呈现弯曲形态。此时弯球囊能够顺应血管弯曲弧度将支架10植入在靶病变血管9中，保证了更好的贴壁效果，减轻了手术过程中支架10对血管的损伤。In the above-mentioned embodiments of the present invention, under the natural state without external force, the outer diameters of the curved balloon body 3 at all positions in the axial direction except the groove lines 4 are equal. If the restraining force received by each position of the balloon body 3 is equal, the outer diameters of the curved balloon body 3 in the axial direction except for the groove lines 4 remain equal at each position. During the procedure, the operator injects a contrast agent into the balloon dilatation catheter, and the curved balloon is inflated to dilate blood vessels narrowed by disease. During the filling process of the curved balloon, the diameter of the curved balloon gradually expands, and the outer wall of the curved balloon or the stent 10 press-fitted on the curved balloon will exert a radial support force on the inner wall of the blood vessel, and at the same time, the blood vessel will also exert a force on the curved balloon. The reaction force directed to the inside of the curved balloon can also be called the binding force. If the target lesion blood vessel 9 has no natural curvature, the binding force received by each position of the balloon body 3 is equal, and the curved balloon will not present a curved shape. If the target lesion blood vessel 9 is naturally curved, the binding force received by each position of the balloon body 3 is not equal, and the curved balloon will assume a curved shape. At this time, the curved balloon can implant the stent 10 in the target diseased blood vessel 9 in compliance with the curvature of the blood vessel, ensuring a better wall-attachment effect and reducing the damage of the stent 10 to the blood vessel during the operation.
在本实用新型上述实施例中，弯球囊主体3上凹槽纹路4的深度为弯球囊主体3壁厚的5％～15％，弯球囊主体3上凹槽纹路4的宽度为弯球囊主体3壁厚的10％～30％。In the above embodiments of the present utility model, the depth of the groove lines 4 on the curved balloon body 3 is 5% to 15% of the wall thickness of the curved balloon body 3, and the width of the groove lines 4 on the curved balloon body 3 is 10%-30% of the wall thickness of the balloon main body 3 .
凹槽纹路4的深度范围在弯球囊主体3壁厚的5％～15％之间，较佳的设置凹槽纹路4的深度为弯球囊主体3壁厚的10％。凹槽纹路4的宽度范围在弯球囊主体3壁厚的10％～30％之间，较佳的，设置凹槽纹路4的宽度为弯球囊主体3壁厚的20％。凹槽纹路4的设置使得弯球囊在充压和保压过程中，当弯球囊任意一侧受外力成延展状态时，对侧就会相应的收紧，从而形成弧形，由此实现了弯球囊在不受操作者控制的情况下，可以顺应病变部位血管弯曲的弧度和方向自行弯曲。The depth of the groove lines 4 is between 5% and 15% of the wall thickness of the curved balloon body 3 , and the depth of the groove lines 4 is preferably set at 10% of the wall thickness of the curved balloon body 3 . The width of the groove lines 4 is between 10% and 30% of the wall thickness of the curved balloon body 3 , preferably, the width of the groove lines 4 is set to be 20% of the wall thickness of the curved balloon body 3 . The setting of the groove pattern 4 makes the curved balloon in the process of inflating and maintaining pressure, when any side of the curved balloon is stretched by external force, the opposite side will be tightened correspondingly, thereby forming an arc, thereby realizing The curved balloon can bend itself according to the curvature and direction of the blood vessel in the lesion without the control of the operator.
在本实用新型上述实施例中，凹槽纹路4的密度，是根据弯球囊规格和靶病变血管9的具体状况而变化的；纹路越密集，弯球囊越柔软。直径较大的血管弯曲弧度较小则所需弯球囊凹槽纹路4密度较小，直径较小的血管弯曲弧度较大则所需弯球囊凹槽纹路4密度较大。此设计既可以起到增加弯球囊柔顺性的效果，又可以保证弯球囊的机械性能(如顺应性和爆破强度等)达到设计要求。具体纹路密度设计可参见下表：In the above embodiments of the present invention, the density of the groove pattern 4 varies according to the specifications of the curved balloon and the specific conditions of the target diseased blood vessel 9; the denser the pattern, the softer the curved balloon. A blood vessel with a larger diameter has a smaller bending arc and requires a lower density of the groove pattern 4 of the curved balloon, and a blood vessel with a smaller diameter has a larger bending arc and requires a higher density of the groove pattern 4 of the curved balloon. This design can not only increase the flexibility of the curved balloon, but also ensure that the mechanical properties of the curved balloon (such as compliance and burst strength, etc.) meet the design requirements. The specific texture density design can be found in the table below:
如图2所示，弯球囊主体3上凹槽纹路4的密度相等。此规格的弯球囊各个位置的柔软度相等。As shown in FIG. 2 , the densities of the groove lines 4 on the curved balloon body 3 are equal. The softness of each position of the curved balloon of this specification is equal.
在本实用新型上述实施例中，如图3和图4所示，弯球囊主体3上凹槽纹路4的密度由球囊远端锥体21向球囊近端锥体22的方向递增，或者由球囊远端锥体21向球囊近端锥体22的方向递减。In the above-mentioned embodiment of the present invention, as shown in Fig. 3 and Fig. 4, the density of the groove lines 4 on the curved balloon body 3 increases from the cone 21 at the distal end of the balloon to the cone 22 at the proximal end of the balloon, Or the direction decreases gradually from the cone 21 at the distal end of the balloon to the cone 22 at the proximal end of the balloon.
