A tracheal tube for foreign bodies, which belongs to the technical field of medical instruments, which comprises a sleeve, a supporting rod, a supporting spring, a ring, a handle, an expansion wire, which is characterized in that the sleeve is sheathed with a sliding support rod and the outer diameter of the inner diameter of the sleeve to support, a support spring is connected between the surface and the bottom end of the sleeve rod right the supporting rod, the right end of the side wall of the vertical fixed limit pin, rectangular axial limit pin through the bottom wall of the sleeve above the through hole and is fixedly connected with the handle sleeve, right side wall and a vertical fixed ring corresponding to the supporting rod and the sleeve; between the left end of the left outer wall uniform even with multiple arc expansion steel wire. The utility model has the advantages of simple structure and convenient operation. When the tubular foreign body is taken out of the trachea, the tubular foreign body can be taken out without opening the tracheal wall, thereby avoiding damage to the tracheal wall and reducing the pain of the patient.
【技术实现步骤摘要】
气管管状异物取出器
:本技术属于医疗器械
,具体地说是一种气管管状异物取出器。
技术介绍
:在临床上经常遇到异物掉入气管中的患者,大多数异物通过现有的异物取出钳就能将异物取出。但有时会遇到管状异物,这种异物掉入气管后与气管壁结合紧密,如用目前的气管异物取出钳钳取则必须将气管壁撑开,撑开的过程中易损伤气管壁,给病人带来很大痛苦。
技术实现思路
:本技术的目的在于克服上述不足,提供一种在取出管状异物时不会对气管壁造成损伤的气管管状异物取出器。本技术的目的是这样实现的:该气管管状异物取出器包括套筒、支撑杆、支撑弹簧、指环、手柄、弧形扩张钢丝,套筒内部滑动套装着外径与套筒内径相适应的支撑杆,支撑杆右端面与套筒筒底之间连有支撑弹簧,支撑杆右端侧壁垂直固定着限位销,限位销下端穿过套筒筒壁上面的长方形轴向通孔后与指环固定相连,套筒右端外壁垂直固定着与指环相对应的手柄;支撑杆左端与套筒左端外壁之间均匀的连有多条弧形扩张钢丝。使用时,将支撑杆左端插入管状异物内,然后握紧指环和手柄,支撑杆便可拉动弧形扩张钢丝进行膨胀,膨胀后的弧形扩张钢丝即可顶紧管状异物内壁,从而将管状异物取出。本技术的优点:结构简单,操作方便,在取出气管内管状异物时,不用将气管壁撑开即可将管状异物顺利取出,避免对气管壁造成损伤,减轻病人痛苦。附图说明:图1为本技术的结构剖视图。具体实施方式:以下结合图1对本技术作进一步详细描述:该气管管状异物取出器包括套筒1、支撑杆2、支撑弹簧3、指环4、手柄5、弧形扩张钢丝6,套筒I内部滑动套装着外径与套筒I内径相适应的支撑杆2,支撑杆2右端面与套筒I筒底之间连 ...
