Abstract

一种骨科取钉器涉及骨科医疗器械。包括固定装置和取钉装置二部分,固定装置为可卡于骨干上的倒U形固定架,其顶部具有可穿过钻具的孔。取钉装置包括钻筒和夹具,钻筒前端锯齿状,钻筒前端内壁向心倾斜,钻筒后端具有钻筒帽,钻筒帽顶部具有可与电钻连接的插接柱,夹具相配合的处于钻筒腔内,夹具前端呈瓣页状。本实用新型的有益效果是:将该取钉器对准断钉在骨干上钻孔,当接触到断钉时停止电钻,此时可取下电钻和钻筒帽,用板手或徒手拧动夹具后尾端棱柱,使夹具瓣页状前端伸出钻筒,并夹住断钉,然后将钻筒、夹具及所夹断钉从骨干孔上一并拔出,断钉被取出。

Description

一种骨科取钉器
技术领域:
本实用新型涉及医疗器械,特别涉及骨科手术断钉取钉器。
背景技术:
骨折手术需在骨折复位后用螺钉固定钢板,将骨折连接起来。螺钉植于体内后,受承重、肌应力作用、疲劳腐蚀等常使螺钉折断。对断螺丝钉的取出,现有办法,一是用骨钻钻孔,再用骨嵌将断钉取出,如此需钻的孔较大,二是用骨凿在断钉周围将骨皮质凿洞。上述均对骨骼组织造成较大损伤,且取钉时间长,给患者造成较大痛苦。
实用新型内容:
本实用新型的目的,是提供一种骨科取钉器,它操作方便,取断钉效果好,对骨干损伤小。
实用新型的技术方案,一种骨科取钉器,包括固定装置和取钉装置二部分,特征是,所述固定装置为可卡于骨干上的倒U形固定架,固定架顶部具有可穿过钻具的孔9,固定架其二支腿底端具有可顶紧骨干的螺丝10。所述取钉装置包括钻筒1和夹具4,钻筒前端锯齿状,钻筒前端内壁7向心倾斜,钻筒后端具有可与钻筒后端活动插接的钻筒帽2,钻筒帽顶部具有可与手电钻连接的插接柱3,夹具4相配合的处于钻筒腔内,夹具前端呈瓣页状6,夹具后端与钻筒后端内腔壁螺纹连接,夹具后尾部5呈棱柱状。
实用新型的有益效果:
该取钉器夹具与钻筒内壁螺纹连接,钻筒与其帽插接,钻筒帽顶端插接柱与电钻插接。将固定装置倒U形固定架固定于断钉处的骨干上。将钻筒穿过固定装置顶部孔9,对准断钉在骨干上钻孔,当接触到断钉时停止电钻,此时可取下电钻和钻筒帽,用板手或徒手拧动夹具后尾端棱柱5,使夹具瓣页状前端伸出钻筒,并夹住断钉,因钻筒前端内壁7向心倾斜,故夹具瓣页状前端伸出钻筒后随拧动后尾端棱柱,夹具瓣页将紧紧夹住断钉,然后将钻筒、夹具及所夹断钉从骨干孔上一并拔出,断钉被取出。
附图说明:
附图1本实用新型主视剖面图
附图2本实用新型固定装置主视图
具体实施方式:
实施方式一种骨科取钉器,包括固定装置和取钉装置二部分,固定装置为可卡于骨干上的倒U形固定架,固定架其顶部具有可穿过钻筒的孔9,固定架其二支腿底端具有可顶紧骨干的螺丝10。
取钉装置包括钻筒1和夹具4,钻筒前端锯齿状,钻筒前端内壁7向心倾斜,钻筒后端具有可与其活动插接的钻筒帽2,钻筒帽顶部具有可与手电钻连接的插接柱3。夹具相配合的处于钻筒腔内,夹具前端呈瓣页状6,夹具后端与钻筒后端内腔壁螺纹连接,夹具后尾部5呈棱柱状。
