发明内容：Summary of the invention:
本发明的目的， 就是针对现有技术所存在的不足，而提供一种扩 张管助推器技术方案， 该方案有一能夹紧扩张管的夹紧套， 在进行穿 刺手术时， 可借助夹紧套进行推入， 方便了穿刺手术的进行。 The object of the present invention is to provide a technique for expanding the tube booster according to the deficiencies of the prior art, which has a clamping sleeve capable of clamping the expansion tube, and can be clamped by the puncture operation. The push is pushed in, which facilitates the puncture operation.
本方案是通过如下技术措施来实现的：本方案的特点是有一个柱 体形夹紧套， 该夹紧套内过夹紧套轴线平面的一侧有活动夹紧块孔， 在所述的活动夹紧块孔内有与活动夹紧块孔配合的活动夹紧块，在所 述的夹紧套和活动夹紧块的接触面上有轴线与夹紧套轴线同轴的夹 针孔； 在所述的夹紧套侧壁上有轴线垂直夹紧套轴线的螺纹孔， 该螺 纹孔内配合有夹紧螺栓，在活动夹紧块上对应所述的夹紧螺栓有定位 盲孔。 本方案具体的特点还有， 所述的夹紧套为圆柱形柱体。 所述的 夹紧套为矩形柱体。所述的夹紧套为多面柱体。所述夹针孔的横截面 为圆形。所述夹针孔的横截面为矩形。所述夹针孔的横截面为多边形。 本方案的有益效果可根据对上述方案的叙述得知，由于在该方案 中有一个柱体形夹紧套，该夹紧套内过夹紧套轴线平面的一侧有活动 夹紧块孔，在所述的活动夹紧块孔内有与活动夹紧块孔配合的活动夹 紧块，在所述的夹紧套和活动夹紧块的接触面上有轴线与夹紧套轴线 同轴的夹针孔。在所述的夹紧套侧壁上有轴线垂直夹紧套轴线的螺纹 孔， 该螺纹孔内配合有夹紧螺栓， 在活动夹紧块上对应所述的夹紧螺 栓有定位盲孔。这一结构，由于在夹紧套和活动夹紧块之间有夹针孔， 扩张管可在夹针孔内由夹紧螺栓紧固。在进行穿刺手术时， 由于夹紧 套要比扩张管的直径大， 便于用力推动， 因此， 在进行穿剌时， 可借 助夹紧套进行推入， 方便了穿刺手术的进行， 解决了穿刺手术在施术 时费力和费时的问题。 由此可见， 本发明与现有技术相比， 具有突出 的实质性特点和显著的进步， 其实施的有益效果也是显而易见的。 附图说明：The solution is achieved by the following technical measures: the feature of the solution is that there is a cylindrical clamping sleeve, and the clamping sleeve has a movable clamping block hole on one side of the axial plane of the clamping sleeve, in the activity a movable clamping block that cooperates with the movable clamping block hole in the clamping block hole, and a pinhole with a coaxial axis and a clamping sleeve axis on the contact surface of the clamping sleeve and the movable clamping block; The side wall of the clamping sleeve has a threaded hole with an axis perpendicular to the axis of the clamping sleeve, and the threaded hole is fitted with a clamping bolt, and the clamping bolt corresponding to the movable clamping block has a positioning blind hole. A specific feature of the solution is that the clamping sleeve is a cylindrical cylinder. The clamping sleeve is a rectangular cylinder. The clamping sleeve is a multi-faceted cylinder. Cross section of the pinhole It is round. The pinhole has a rectangular cross section. The pinhole has a polygonal cross section. The beneficial effects of the present solution can be known from the description of the above solution. Since there is a cylindrical clamping sleeve in the solution, the clamping sleeve has a movable clamping block hole on one side of the axial plane of the clamping sleeve. The movable clamping block hole has a movable clamping block that cooperates with the movable clamping block hole, and the clamping surface of the clamping sleeve and the movable clamping block has a clamp coaxial with the axis of the clamping sleeve. Pinhole. On the side wall of the clamping sleeve, there is a threaded hole with an axis perpendicular to the axis of the clamping sleeve. The threaded hole is fitted with a clamping bolt, and the clamping bolt corresponding to the clamping bolt has a positioning blind hole. In this configuration, since there is a pinhole between the clamping sleeve and the movable clamping block, the expansion tube can be fastened by the clamping bolt in the pinhole. In the puncture operation, since the clamping sleeve is larger than the diameter of the dilating tube, it is easy to push hard. Therefore, when the perforating is performed, the clamping sleeve can be pushed in, which facilitates the puncture operation and solves the puncture operation. A laborious and time consuming problem in the operation. It can be seen that the present invention has outstanding substantive features and significant advances as compared with the prior art, and the beneficial effects of the implementation thereof are also obvious.
