Abstract
本实用新型涉及一种剥脱静脉分支血管用的静脉剥脱钩，其结构是在钩柄的前端制有下垂的U型钩，U型钩的平面与钩柄的夹角为85°～110°。使用本剥脱钩，先在皮肤上切出约2mm的微小切口，然后将U型钩顺切口伸入皮下，将皮下的曲张静脉分支血管分段钩出，再钳夹抽剥，最后剪断，即可完成分支血管的分段剥脱。使用本实用新型具有成本低和操作简便的特点，并且还具有不需缝合创口、出血少、术后无疤痕等优点，可最大限度地减少手术创伤、手术用时和手术费用，适于在各级各类医院普及使用。
Description
技术领域
本实用新型涉及一种医用外科手术器具，具体地说是一种静脉剥脱钩。
技术背景
大隐静脉曲张是外科常见病，多发病。传统的治疗方法是采用定位结扎大隐静脉的主干和分支，然后剥脱大隐静脉主干，对大隐静脉的分支血管则采取分段切除的方法进行治疗。这种治疗方法的缺点是手术切口大，创面多，术后疤痕多，并且还易伤及下肢肌组织和神经组织。近期有用射频、旋刀等方法切除大隐静脉分支的报道，但这种方法的器械费用高，创面大，在一般的中小医院难以推广。
实用新型内容
本实用新型的目的就是提供一种不需缝合、操作简便的专用于剥脱大隐静脉分支部分的静脉剥脱钩。
本实用新型是这样实现的：一种静脉剥脱钩，在钩柄的前端制有下垂的U型钩，U型钩的平面与钩柄的夹角为85°～110°。
在大隐静脉主干被先期结扎、剥脱或者采用激光闭锁的情况下，用手术刀在皮肤上切出约2mm的微小切口，然后使用本剥脱钩，将钩端顺切口伸入皮下，将皮下的曲张静脉分支血管分段钩出，再用止血钳夹住伸出段，旋拧抽剥，最后将血管两端剪断，即可完成分支血管的分段剥脱。使用本实用新型对大隐静脉分支血管实施分段剥脱，具有成本低和操作简便的特点，并且还具有不需缝合创口、出血少、术后无疤痕等优点，可最大限度地减少手术创伤、手术用时和手术费用，因而适于各级各类医院普及使用。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图1所示，本静脉剥脱钩的钩柄2为有一定锥度的细杆，钩柄的前端制有下垂的U型钩3，U型钩的平面与钩柄的夹角为85°～110°，过大或过小的夹角，都不利于剥脱操作，一般以略大于90°的夹角为宜。在钩柄2的后端可制出一个较宽段的手持柄1，以便于手持操作。
为减小切口，U型钩3不宜过大，其上口宽度以1.5～2.2mm为宜，其钩口深度以1.5～3.0mm为宜。
Claims (2)
1.一种剥脱静脉分支血管用的静脉剥脱钩，其特征在于在钩柄(2)的前端制有下垂的U型钩(3)，U型钩的平面与钩柄的夹角为85°～110°。
2.根据权利要求1所述的静脉剥脱钩，其特征在于U型钩(3)的上口宽度为1.5～2.2mm，钩口深度为1.5～3.0mm。
