胆道用取石球囊制造技术

一种胆道用取石球囊,包括球囊接口(1)、鞘管(2)和球囊(3),所述鞘管(2)的近端连接所述球囊接口(1),所述鞘管(2)的远端外侧套设所述球囊(3),所述鞘管(2)在套设所述球囊(3)处设有孔口；所述球囊(3)的两端部固定在所述鞘管(2)的外侧壁上,在所述球囊(3)的两端部之间是球囊(3)的有效可充盈部分,所述球囊(3)的有效可充盈部分为径向可伸缩的,且所述球囊(3)在充盈后呈径向尺寸(D)大于轴向尺寸(H)的扁平状。所述胆道用取石球囊在使用时能够减小摩擦阻力,同时更易取出泥沙状结石,进而可以缩短手术时间,减少患者痛苦；通过设置球囊充盈回复结构(4),可以调节球囊(3)在收缩回复时的回复速度,解决了球囊(3)充盈后回复速度过快的问题。

Lithotomy balloon for biliary tract

A bile duct stone with balloon balloon, including interface (1), (2) and balloon sheath (3), the sheath (2) attached to the proximal end of the balloon interface (1), the sheath (2) distal sleeved outside the balloon (3). The sheath (2) in the set of the balloon (3) is provided with a hole; the balloon (3) the two ends fixed on the sheath (2) on the outer side wall of the balloon (3) between the two ends of the balloon (3) is the effective part of filling the balloon (3), the effective filling part is radial retractable, and the balloon (3) is in the radial dimension after filling (D) is greater than the axial dimension (H) flat. The use of biliary stone balloon can reduce the friction resistance when in use, but also easy to remove sand like stones, which can shorten the operation time, reduce the pain of patients; reply structure by setting the balloon (4), can adjust the balloon (3) in response to the contraction of recovery speed, solve the balloon (3) filling after the fast speed of response.
