本发明第二实施例的包皮环切缝合器包括相互交叉并铰接的第一操作手柄 1和第二操作手柄 2，所述第一操作手柄和第二操作手柄的前端分别设置圆弧形 的第一切割环 11和第二切割环 21， 第一切割环或第二切割环所在的平面与第 一操作手柄和第二操作手柄所在的平面相垂直， 第一操作手柄和第二操作手柄 的尾端分别设置用于控制第一切割环 11和第二切割环 21之间距离的多级卡扣 3' ； 第一切割环上沿圆弧方向均匀设置多个凸起 12， 第二切割环上设置多对 与凸起相对应的缝隙 22，第一切割环和第二切割环重叠时缝隙与凸起的两侧对 齐， 还包括以可拆卸的方式设置在第一切割环外侧的尺子 4， 尺子 4的外沿为 圆弧形且与第一切割环 11上的凸起 12外沿相对齐； 还包括以可拆卸的方式设 置在第二切割环外侧的底座 5，第一切割环 11与第二切割环 21闭合时，尺子 4 与底座 5之间沿切割环的径向有用于供手术刀划入的间隙 6。 本实施例中， 所 述尺子 4和底座 5的一端以包裹或半包裹的方式分别固定套设在第一切割环 11 和第二切割环 21的自由端，另一端以开叉卡位的方式分别固定咔合在第一操作 手柄 1和第二操作手柄 2的前端。
本发明第二实施例的环切缝合器的使用方法为： 先将待切除的多余包皮用 第一切割环和第二切割环夹紧， 压迫止血， 将尺子和底座分别安装在第一切割 环和第二切割环上， 然后再用手术刀沿着尺子的外沿划入间隙， 将多余的包皮 划掉， 即可得到连贯、 整齐、 标准、 美观的包皮切口， 最后将尺子和底座拆除 后进行八字缝合， 拆下缝合器即可。 利用本发明所述切割器进行包皮切除和缝 合，手术效率提高了 2— 3倍，大大缩短了手术时间，而且包皮切口连贯、整齐、 美观， 易于缝合， 而且较好地实现了标准化切除， 不同的操作医生的切除结果 一致， 治愈后包皮形状美观， 不影响患者心理。
另外， 本实施例中， 所述尺子 4和底座 5也可以以销孔过盈配合的方式设 置在第一切割环 11和第二切割环 21上。 此连接方式简单， 拆卸方便， 有利于 节约手术时间。
最后说明的是， 以上实施例仅用以说明本发明的技术方案而非限制， 尽 管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理 解， 可以对本发明的技术方案进行修改或者等同替换， 而不脱离本发明技术 方案的宗旨和范围， 其均应涵盖在本发明的权利要求范围当中。
