    • A stent includes a stent body in which struts are joined mutually while intersecting and which is formed tubularly as a whole, and a drug coat layer on the outer surface of the struts. The strut has a bend which is deformed as the stent body expands/contracts in the radial direction, and the drug coat layer with which the bend is coated is formed in such a manner that the drug coat layer is mountain-shaped in a cross-section perpendicular to the axis of the strut and the ridgeline of the mountain shape extends in a wavy shape along the longitudinal direction of the strut. The drug coat layer deforms relatively easily without using plasticizer as the stent deforms and is not so susceptible to causing problems such as peeling, destruction, damage or falling off of the drug coat later.
    • 支架包括支架,其中支柱相互交叉地相互连接并且整体上形成为管状,支架外表面上的药物涂层。 支架具有随着支架主体沿径向方向扩张/收缩而变形的弯曲部,并且以这样的方式形成涂覆有弯曲部的药物涂层,使得药物涂层在横截面中呈山形, 垂直于支柱的轴线的截面和山形的脊线沿着支柱的纵向方向呈波浪形状延伸。 当涂层变形时,药物涂层相对容易变形而不使用增塑剂,并且不太容易引起诸如以后的药物外皮的剥离,破坏,损坏或脱落等问题。

    • To facilitate insertion of an implant while retaining a cut in an opened state. There is provided a spreader 1 for high tibial osteotomy to be inserted into a cut made in the deformed femur or tibia of a patient with knee osteoarthritis, and to open the cut so as to make a space that allows insertion of an implant, comprising: two pairs of swinging members 2a/2b and 3a/3b which are respectively connected in a relatively swingable manner by hinge parts 6 and 7 disposed at the distal end; and two opening/closing mechanisms 4 and 5 which open/close these two pairs of swinging members 2a/2b and 3a/3b respectively about the axes of the hinge parts 6 and 7, wherein the two pairs of swinging members 2a/2b and 3a/3b are detachably assembled in the axial directions of the hinge parts 6 and 7.
    • 为了便于植入物的插入,同时保持切口处于打开状态。 提供了一种用于高胫骨截骨术的扩张器1,其被插入到患有膝关节骨性关节炎的变形股骨或胫骨中的切口中,并且打开切口以形成允许植入物插入的空间,包括: 两对摆动构件2a / 2b和3a / 3b分别通过设置在远端的铰链部分6和7以相对可摆动的方式连接; 以及分别围绕铰链部件6和7的轴线打开/关闭这两对摆动构件2a / 2b和3a / 3b的两个打开/关闭机构4,5,其中两对摆动构件2a / 2b和3a 3b可沿铰链部分6和7的轴向可拆卸地组装。
