Description

说明书 发明名称：一种带计数功能的止血钳 技术领域
[0001] 本发明涉及医疗工具技术领域， 具体涉及一种通过击发钛钉用于止血的止血钳 [0002] 背景技术
[0003] 一般在医疗手术过程中， 为了避免目标器官因为流血量过多或者血管破裂导致 手术的困难度增加， 都会先将连接目标器官的血管利用钛钉先进行结扎止血的 动作， 而所使用的器具就是止血钳。 止血钳的作用方式是先将止血钳伸入人体 内， 再将钛钉圈住血管的周围， 并从外部施加力量带动夹钳将钛钉夹紧， 以达 到止血的效果。 然而一般止血钳在使用吋已经伸入人体内， 此吋医护人员无法 精确了解止血钳内部是否仍然有钛钉， 若此吋钛钉已用完， 则夹钳会直接对血 管进行夹合， 导致血管有被夹破裂的危险， 存在极大的安全隐患。 为此， 有人 设计了止血钳的空钉锁止机构以避免空击， 然而， 空钉锁止机构在结构上都是 比较复杂的， 而且即使有空钉锁上机构， 操作者在止血钳伸入人体内的情况下 也无法获知是否还有钛钉或者然钉的具体数量， 这样依然会给使用带极大的不 便， 甚至影响手术的正常进行。

[0037] 参照图 10， 所述枪管部分包括有枪管 11、 主骨架 12和推杆 13， 主骨架 12后端安 装于主轴 24中， 推杆 13后端通过固定后座安装于前套环 22内， 下钳部 10固定于 主骨架 12前端， 上钳部 110固定于推杆 13前端构成可移动结构； 后段推片 14和前 段推片 15设于一后座上， 后座设于后套环 23上； 钉座 17固定在主骨架 12上， 钉 座固定片 19从钉座 17后端插入其一部分顶住钉座推片 18， 后段推片 14的后端焊 接在前段推片 15前端， 后段推片 14上的弹片勾住钉座推片 18底部沟槽。
[0038] 扣动扳机部分 3的扳机 31吋， 分段定位片 35和齿轮片 32下端的定位齿 34相接， 定位弹簧 36拉动分段定位片 35， 使扳机可分段击发。 扳机 31上连接的拨动片 33 直接作用于前套环 22实现击发， 前套环 22与后套环 23—起安装于主轴 24上， 主 轴及前、 后套环均由塑胶材质制成， 主轴由可相互扣合的两部分构成； 而拨针 固定支架 25连接拨动后套环， 因而在扣动扳机 31吋， 前套环 22与后套环 23是反 向动作的。 前套环 22向枪管方向移动， 固定后座和带动推杆 13向前移动， 上钳 部 110向前滑动使夹子闭合， 夹子 16顶端的钛钉亦闭合； 后套环 23带动后段推片 14、 前段推片 15及后座向后移动， 后段推片 14上设有可以勾住钉座推片 18底部 沟槽的弹片， 后段推片后移吋， 弹片脱幵钉座推片的沟槽。 松幵扳机吋， 后段 推片向前移动， 带动钉座推片向前移动， 将钛钉一并推向前。
[0039] 第一次击发之后， 拨动片 33向左， 拨针固定支架 25向右， 拨针 27向左倒， 不推 动齿条板， 计数器不动。 松幵扳机， 拨针 27顶住齿条板左移， 计数器移动一格 ； 再次扣扳机， 拨针固定支架 25向右使齿条板归位， 计数器不动。
[0040] 扣动扳机 31吋， 齿条板 54受回位弹簧 50复位之力向右平移， 传动齿轮 55反转， 经过渡齿轮 56后使计数主动轮 52正转， 计数转轮 51不动。 松幵扳机 31吋， 在拨 动弹簧 38作用下， 扳机 31复位， 通过拨动连杆 37的作用， 齿条板被拨针 27压向 左平移， 计数主动轮 52逆吋针转动， 与传动齿轮 55脱幵， 计数转轮 51移动一格
[0041] 以上已将本发明做一详细说明， 以上所述， 仅为本发明之较佳实施例而已， 当 不能限定本发明实施范围， 即凡依本申请范围所作均等变化与修饰， 皆应仍属 本发明涵盖范围内。
