Medical device for extracting foreign objects

The invention relates to the technical field of medical instruments, in particular to a medical device for extracting foreign objects, comprising an extraction mechanism and a press mechanism; the extraction mechanism includes a support sleeve, a first hinging head, a second hinging head, a link component, a jacket and two support plates; in the medical device, the press mechanism controls movement of the extraction mechanism, the second hinging head moves down long the support sleeve, the support plates are lowered via the link component to be as high as a foreign object, and the foreign object is held by rotation trough a V-shaped notches of the support plates and is extracted. The medical device is simple to operate, can treat a foreign object inlaid transversely, with less accessory damage caused by an endoscope. 本发明涉及医疗器械技术领域，特别涉及种医疗取异物的装置；本发明包括取出机构和按压机构；取出机构包括支撑管套、第铰接头、第二铰接头、连杆组件、外套和两块撑板；在本发明中，按压机构控制取出机构的运动，第二铰接头在支撑管套上向下运动，通过连杆组件将撑板下降至与异物同高度，再旋转通过撑板上的V型槽口夹住异物，再取出；本发明操作简便，同时可以处理横贯嵌顿的异物，减少内镜操作带来的副损伤。
