Description

腹腔镜胆囊切除术碎石取石钳
技术领域:本实用新型涉及一种医疗器械,具体的说是一种腹腔镜胆囊切除术碎石取石钳,它适用于腹腔镜胆囊切除术。
背景技术:目前,腹腔镜胆囊切除术腹壁最长切口一般为10mm,胆囊结石直径大于10mm,特别是直径大于15mm的结石,或结石过多时,切除的胆囊就不能顺利取出,通常用血管钳扩大切口,或血管钳/胆石钳夹碎结石取出,有时需延长切口,手术创伤大,由于血管钳头部窄、尖,胆石钳适宜胆道取石,对于胆囊内坚硬的结石,碎石、取石困难,且结石易滑脱,费时费力,且有胆囊破漏,胆汁、结石进入腹腔等缺点。
发明内容:本实用新型的目的是要提供一种能防止结石滑脱,碎石、取石容易,并可同时完成,缩短手术时间,可避免扩大切口,不会戳破胆囊的腹腔镜胆囊切除术碎石取石钳。
本实用新型的目的是采用以下方案实现的:
该取石钳是由二叶匹配成对的钳身和鳃轴组成的金属钳,该对钳身借助鳃轴铰接在一起,钳身含钳头、钳体、钳柄和指环,钳头为长圆形,中间有长圆形孔,咬合面带有齿:一叶为横向齿,一叶为纵向齿,钳柄有侧弯,闭合后钳体呈线形。
本实用新型结构简单,操作简便、快捷,使用时,先将胆囊颈部提至腹壁外,剪开胆囊,吸除胆汁,即可进行碎石取石,由于闭合后钳体呈线形,钳身长短适宜,即便通过肥胖病人的腹壁也很容易操作;钳头长圆形,中间有长圆形孔,咬合面有齿:一叶为横行,一叶为纵行,防止结石滑脱,碎石、取石容易,并可同时完成,省时省力,不会戳破胆囊;钳柄有侧弯,利于加力。避免延长切口。
附图说明:
图1为本实用新型的结构示意图
图2为本实用新型的咬合面结构示意图
图3为本实用新型的另一咬合面结构示意图
具体实施方式:
图中1钳头,2钳体,3鳃轴,4钳柄,5指环,6内孔,7咬合面。
该器械全长200~240mm,穿鳃或叠鳃式结构,头端至鳃轴中心长80mm,钳头咬合面长宽15~20×8~10mm,内孔长宽8~10×3~4mm,闭合后两钳柄相距20mm。
