Abstract

一种用于腹腔镜辅助胃肠道手术的墩头肠钳,是由:钳臂,销轴,钳把,钳扣,钳头,通孔构成;两根钳臂以销轴为中心对应设置,两根钳臂的一侧设置钳把,另一侧设置钳头,钳把上设置钳扣,两钳扣对应咬合,钳头为C形曲面结构,钳头中部设置通孔,钳头的各角为平滑圆角,钳头的端面为平面或浅弧形。在钳头夹住肠管向腹腔还纳时,钳头的各角为平滑圆角使肠管能安全地还纳入腹腔,还纳过程安全可靠,有效地保护了肠管,避免了钳头的尖角刺破肠腔造成伤害。

Description

一种用于腹腔镜辅助胃肠道手术的墩头肠钳
技术领域
本实用新型涉及医疗器械装置,尤其是一种用于腹腔镜辅助胃肠道手术的墩头肠钳。 
背景技术
目前,在腹腔镜辅助胃肠道手术过程中,经常需要在腹部做5cm左右的辅助切口,通过该切口将肠管提出腹腔进行肠切除、吻合等操作,操作完成后,需要将肠管还纳入腹腔;目前普遍使用传统开腹手术器械中的肠钳、环钳或鼠齿钳,由于这些器械顶端都很小,在其夹住肠管向腹腔还纳的时候,钳子的尖端可能刺入肠腔或系膜,造成严重的损伤。 
申请号为20100013389.0的专利文件公布了一种卵圆钳,钳嘴尖端易刺破肠管,不适合腹腔镜胃肠道手术使用。 
鉴于上述原因,现有的肠钳结构需要改进。 
实用新型内容
本实用新型的目的是为了克服现有技术中的不足,提供一种用于腹腔镜辅助胃肠道手术的墩头肠钳,有效地保护了肠管避免了尖形钳头刺破肠腔造成伤害。 
本实用新型为了实现上述目的,采用如下技术方案:一种用于腹腔镜辅助胃肠道手术的墩头肠钳,是由:钳臂,销轴,钳把,钳扣,钳头,通孔构成; 两根钳臂以销轴为中心对应设置,两根钳臂的一侧设置钳把,另一侧设置钳头,钳把上设置钳扣,两钳扣对应咬合,钳头为C形曲面结构,钳头中部设置通孔,钳头的各角为平滑圆角,钳头的端面为平面或浅弧形。 
本实用新型的有益效果是:结构简单,设计合理,操作方便,便于携带,将钳头设计成膨大的C形曲面结构,钳头内设置通孔,钳头的端面为平面或浅弧形,钳头的各角为平滑圆角,钳扣可对夹紧程度进行调节;在钳头夹住肠管向腹腔还纳时,钳头的各角为平滑圆角使肠管能安全地还纳入腹腔,还纳过程安全可靠,有效地保护了肠管,避免了钳头的尖角刺破肠腔造成伤害。 
附图说明
下面结合附图对本实用新型作进一步说明: 
图1是,总装立体结构示意图; 
图2是,主视结构示意图; 
图3是,侧视结构示意图; 
图1、2、3中:钳臂1,销轴2,钳把3,钳扣4,钳头5,通孔6。 
具体实施方式
下面结合附图与具体实施方式对本实用新型作进一步详细说明: 
如图所示,两根钳臂1以销轴2为中心对应设置,两根钳臂1的一侧设置钳把3,另一侧设置钳头5,钳把3上设置钳扣4,两钳扣4对应咬合,钳头5为C形曲面结构,钳头5中部设置通孔6,钳头5的各角为平滑圆角,钳头5的端面为平面或浅弧形。
