Abstract

一种可弯曲的腹腔镜手术器械，由钳头、轴销(2)和钳身(3)构成，钳头由钳尖(1)和钳头中间节(5)构成，钳尖(1)和钳头中间节(5)内部设有导索，导索一端与钳尖(1)固定，另一端穿过钳身(3)并与钳身上卡扣固定。导索也采用多节杆套圈连接结构，每节杆的长度与钳头中间节的长度相同。本实用新型以简单明了的结构构成了可弯曲的腹腔镜手术钳，其它夹持器等均可用此结构制备，减少非主要操作器械对于手术操作的影响。

Description

可弯曲的腹腔镜手术器械
技术领域
本实用新型涉及外科手术用的腹腔镜手术器械的结构。
背景技术
在进行腹腔镜外科手术时，特别是进行单孔腹腔镜手术时，由于术野范围小，器械之间互相干扰，影响手术的进行，如果钳头可以进行弯曲，能减少非主要操作器械对于手术操作的影响。
实用新型内容
本实用新型的目的是提出一种可弯曲的腹腔镜手术器械。减少非主要操作器械对于手术操作的影响，使手术更方便，提高手术的质量。
本实用新型的技术方案是，一种可弯曲的腹腔镜手术器械，由钳头、轴销2和钳身3构成，钳头由钳尖1和钳头中间节5构成，钳尖1和钳头中间节5内部设有导索，导索一端与钳尖1固定，另一端穿过钳身3并与钳身上卡扣固定。
本实用新型设计的关键是钳头和钳身之间的连接处有可弯曲的部分，该弯曲部分有互相连接的卡扣组成，当卡扣放松状态时，导索松弛钳头变弯，便于钳子可以自由进出腹腔镜，当卡扣恢复其原有状态，导索张紧钳头变直从而变成完全的钳子，进行操作。当然此钳的钳夹力会低些。
本实用新型的有益效果，以简单明了的结构构成了可弯曲的腹腔镜手术钳，其它夹持器等均可用此结构制备，减少非主要操作器械对于手术操作的影响。使手术更方便，提高手术的质量。
附图说明
图1是本实用新型结构示意图。
具体实施方式
如图所示，钳尖1、轴销2、钳身3、钳头关节4、钳头中间节5、卡扣6。由钳头、轴销2和钳身3构成，钳头由钳尖1和钳头中间节5构成，钳尖1和钳头中间节5相当于将钳头截断后拼接成一钳头的形状，一般截成3-10节即可，图中画了7节；钳尖1和钳头中间节5内部设有钢制导索，导索一端与钳尖1固定，另一端穿过钳身3并与钳身上卡扣固定，卡扣采用螺栓螺丝的螺旋固定并张紧导索结构(导索在卡扣的固定端部是一带螺丝的螺杆)，旋紧可以张紧钳头部位。图中是是一种手术器械的示意图，在腔镜中使用是可以的。本实用新型尤其应用于腔镜手术中。
导索也可以采用与三节棍(杆)或多节棍(杆)的套圈的连接结构，每节杆的长度与钳头中间节的长度相同。因是钢性的连接且可弯曲，卡扣张紧固定后张紧力更大，从而可以保证医生的应用更加可靠。
