Abstract

一种消化道吻合器的穿刺锥与钉座的连接结构,包括钉座、穿刺锥,所述的钉座上固定有卡簧,所述的穿刺锥插在该卡簧之间,卡簧夹紧所述的穿刺锥。依靠卡簧的弹簧卡力,使得钉座能可靠地与穿刺锥相连接或相分离,使用安全、安装方便。

Description

消化道吻合器的穿刺锥与钉座的连接结构
                          技术领域
本实用新型涉及一种医疗器械,特别是消化道吻合器的穿刺锥与钉座的连接结构。
                          背景技术
现有技术中,消化道吻合器是用于肠、胃等消化道的缝合手术之用。手术时,钉座与食管缝接,穿刺锥穿过胃壁,然后把两者相对接,因此穿刺锥与钉座有分离和相连的过程,目前的钉座与穿刺锥之间主要依靠插接进行连接,因此在消化道的吻合手术中,钉座与穿刺锥之间易分离,影响了手术的安全性。
                          发明内容
本实用新型的目的在于提供一种消化道吻合器的穿刺锥与钉座的连接结构,穿刺锥与钉座的连接可靠、使用安全。
本实用新型的技术方案是:一种消化道吻合器的穿刺锥与钉座的连接结构,包括钉座、穿刺锥,所述的钉座上固定有卡簧,所述的穿刺锥插在该卡簧之间,卡簧夹紧所述的穿刺锥。
本实用新型与现有技术相比具有下列优点:
依靠卡簧的弹簧卡力,使得钉座能可靠地与穿刺锥相连接或相分离,使用安全、安装方便。
                          附图说明
附图1为消化道吻合器的整体结构剖视图;
附图2为本实用新型的结构半剖视图;其中:
1、钉座;2、卡簧;3、穿刺锥;4、穿刺锥颈部槽;5、卡簧径向凸起;
                        具体实施方式
参见附图1和附图2,主要参见附图2,一种消化道吻合器的穿刺锥与钉座的连接结构,包括钉座1、穿刺锥3,所述的钉座1上固定有卡簧2,所述的穿刺锥3插在该卡簧2之间,卡簧2夹紧所述的穿刺锥3。
所述的穿刺锥3上设有径向变小的穿刺锥颈部4,卡簧2上具有卡簧径向凸起5,该卡簧径向凸起5插在穿刺锥颈部槽4内。当穿刺锥部分与卡簧一起缩入钉仓体内时,钉仓体限制了卡簧2的径向张开,从而使得卡簧径向凸起5相对于穿刺锥颈部槽4不能轴向移动,则本实用新型的钉座1、穿刺锥3被可靠地连接为一体,只有在附图2的情况下,钉座1才能从穿刺锥3上拔下来。

Claims (2)
