实施该发明的最佳实施例
本发明的最佳实施方式
[0038] 在此处键入本发明的最佳实施方式描述段落。
本发明的实施方式
[0039] 请参阅图 1-9， 本发明提供的医用射线定位薄膜， 包括表面保护层 11、 第一中 间透明层 12、 光显影纤维层 13、 第二中间透明层 14和内侧防粘层 15; 表面保护 层 11、 第一中间透明层 12、 光显影纤维层 13、 第二中间透明层 14和内侧防粘层 1 5由外至内依次贴合， 其中表面保护层 11和第一中间透明层 12直接接触贴合， 第 一中间透明层 12和光显影纤维层 13之间以及光显影纤维层 13和第二中间透明层 1 4之间均用粘结剂粘合， 第二中间透明层 14与内侧防粘层 15接触的一侧涂有压敏 胶， 内侧防粘层 15附于压敏胶上。
[0040] 相较于现有技术， 本发明提供的医用射线定位薄膜， 为无菌医用薄膜， 可以覆 盖在患者病变部位的体表投射区； 在使用 C臂机照射吋， 光显影纤维层 13中的不 透射线的结构在放射图片中呈网状覆盖手术区域， 医生可以根据定位膜上的相 应特殊标记确定手术部位和定位膜标记物的空间位置关系， 从而达到精确操作 目的。 避免了在患者皮肤表面标记， 也不需要另外打幵克氏针增加耗材， 也不 需要反复调整位置。 对于不允许记号笔标记的部位， 薄膜本身保护了创面不被 细菌污染， 同吋起到标记作用， 代替了医用手术薄膜的作用。 定位膜本身也具 有手术薄膜的创面保护作用， 可以替代现有的手术薄膜。
[0041] 请参阅图 5-7， 本发明提供的医用射线定位薄膜， 其光显影纤维层 13至少可以 为以下六种：
[0042] 1， 如图 5所示的基本形式， 无任何标记， 适用于患者病变部位极易辨认， 无需 通过标记即可；
[0043] 2， 如图 6所示， 通过数字和字母的组合标记命名每根光显影纤维的名称以达到 区分顺序、 区域的目的；
[0044] 3， 如图 7所示， 通过具有长轴和短轴的形状来标记光显影纤维层的中心， 比如 图中所示的菱形， 也可为长轴和短轴交叉的十字形；
[0045] 4， 图未示， 通过光显影纤维的颜色或直径来标记光显影纤维层 13的中心、 以 及产品的长轴和短轴。
[0046] 5， 图未示， 通过十字交叉的一道虚线和实线来标记光显影网格层 11。
[0047] 6， 也可为以上五种中的两种或两种以上的组合。
[0048] 当然， 这仅是本发明的光显影纤维层 13几个具体实施例， 其具体结构并不仅限 于此， 也可为其他能够确定病变位置的结构。
[0049] 在本实施例中， 光显影纤维层 13由多条交织排列呈网格状的光显影纤维构成； 网格为正方形， 网格间距为 2cm。
[0050] 正方形的网格， 最简洁， 可较容易的确定位置， 当然， 网格形状并不仅限于此
， 特可谓正方形、 长方形、 正六边形或者其他特殊要求形状； 而光显影纤维的 网格间距可根据手术需求确定， 网格间距为 2cm能满足大多数的手术需求。
[0051] 在本实施例中， 表面保护层 11为医用 PE材料， 但表面保护层的材质并不仅限于 此， 能达到自然直立吋不倒伏， 但是柔软的材料也是此专利的保护范畴。 第一 中间透明层 12和第二中间透明层 14为聚氨酯薄膜； 光显影纤维层 13， 所有的医 用、 光显影纤维都可以作为显影材料， 例如聚丙烯光显影纤维， 显影结构为柔 性结构， 可以达到紧密和皮肤结合的目的； 内侧防粘层 15为防粘纸。
[0052] 当然， 这仅是本发明的一个具体实施例， 本发明的各层的材质并不仅限于此， 也可为其他符合性能要求的其他材质。
[0053] 此外， 本发明还提供第二种医用射线定位薄膜， 包括光显影网格层、 薄膜层和 内侧防粘层， 光显影网格层直接印刷在薄膜层的一面， 薄膜层的另一面涂有压 敏胶， 内侧防粘层附于压敏胶上。 相较于本发明提供的第一种医用射线定位薄 膜， 第二种医用射线定位薄膜采用了三层结构， 生产难度低， 生产效率高， 而 且产品结构更加简洁， 降低了生产成本。
[0054] 在本实施例中， 光显影纤维层具有长轴和短轴,利用十字交叉的虚线和实线来标 记光显影网格层。 可用长短不同的虚线与虚线结合、 实线与实线结合或者实线 与虚线结合三种方式来标记光显影网格层的中心、 以及产品的长轴和短轴。 此 光显影纤维层利于印刷， 生产难度低， 使用也很方便。
[0055] 此外， 本发明还提供一种定位便捷的病变处拍照方法， 包括以下步骤：
[0056] 步骤一， 准备上述的医用射线定位薄膜， 该医用射线定位薄膜的光显影纤维层 的中心位置处设有菱形标记；
[0057] 步骤二， 揭下内侧防粘层， 调整定位薄膜的方向， 使定位膜的中心标记对准病 变位置， 将定位膜长轴同体内的参照物保持平行， 然后将第二中间透明层通过 医用压敏胶粘贴于皮肤表面；
[0058] 步骤三， 用 C臂机照射覆盖有医用射线定位薄膜的病变区， 生成带有光显影纤 维层留下的阴影的图片；
[0059] 步骤四， 医生依据图片中菱形标记的长短轴与体内参照物的方向及所处的网格 ， 判断病变区和网格的具体空间位置关系。
[0060] 相较于现有技术， 本发明提供的定位便捷的病变处拍照方法， 可以在体表定位 膜的相应部位作为进针点直接进针， 避免了在患者皮肤表面标记， 也不需要另 外打幵克氏针增加耗材， 也不需要反复调整位置。 对于不允许记号笔标记的部 位， 薄膜本身保护了创面不被细菌污染， 同吋起到标记作用， 代替了医用手术 薄膜的作用。
[0061] 具体来说， 该方法可用于椎体成形术， 所述体内的参照物为脊柱， 具体过程为 ： 将定位膜的中心标记即菱形标记对准病变椎体， 将定位膜长轴同脊柱保持平 行， 即定位膜中心的菱形标记长轴与脊柱保持平行， 生成的图片， 是被网格覆 盖的椎体， 医生依据图片中定位膜中心的菱形标记判断图片的长轴以及病变椎 体所在的网格； 并且以此图片判断体表的进针位置。
[0062] 此外， 该方法可用于股骨颈骨折闭合复位内固定术， 所述体内的参照物为大腿 长轴， 具体过程为： 将定位膜长轴与大腿长轴保持一致， 定位膜中心菱形标记 基本对准压痛点， 这吋定位膜的菱形标记长轴会同大腿长轴一致， C臂机照射形 成的图片为被网格覆盖的股骨， 医生依据菱形标记同骨折部位的关系， 以及进 针部位同网格的关系， 来确定进针方式及进针点。
[0063] 该方法可用于皮瓣整形手术， 具体过程为： 取相同规格的两张薄膜， 其中一张 贴于皮损区， 另一张贴附于皮瓣供给部位。 依据皮损区边缘对应的网格线得到 的交点， 就可以直接在皮瓣供给部位相应的坐标直接取皮瓣， 而不需要用直尺 反复测量， 尤其对于创面边缘不规则或者曲面的人体部位， 使用非常准确便利
[0064] 当然， 这仅是本发明的三个具体实施例， 本发明提供的定位便捷的病变处拍照 方法还可应用于其他手术中， 其工作原理同上述手术相同。
[0065] 以上仅为本发明的优选实施方式， 应当指出， 对于本技术领域的普通技术人员 来说， 在不脱离本发明技术原理的前提下， 还可以做出若干改进和润饰， 这些 改进和润饰也应视为本发明的保护范围。
