Sheet foreign body removing device and method

Abstract

The invention relates to a sheet foreign body removing device and method and belongs to the technical field of medical apparatuses and instruments. The sheet foreign body removing device comprises a fixing device, a protecting device, a cutting device and an imaging device, wherein the fixing device comprises a case, a first pushrod, a second pushrod, a retractable flexible shaft, a main clamp, afirst auxiliary clamp and a second auxiliary clamp; the protecting device comprises a net, a net driver and a net shape limiter; the cutting device comprises a laser generator, a laser cutting head and a cutting driver, the laser cutting head is integrally arranged at the bottom of one side of the laser generator, one end of the cutting driver is fixed to the other side of the laser generator, andthe other end of the cutting driver extends to in vitro; the imaging device comprises a camera and a display. On the one hand, the sheet foreign body removing device can cut foreign bodies to reducethe widths of the foreign bodies and meanwhile reduce the possibility of contact with digestive tracts, and on the other hand, can protect the digestive tracts to avoid direct contact between the foreign bodies and the walls of the digestive tracts and accordingly to provide assistance for non-invasive digestive tract foreign body removal.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for taking sheet-shaped foreign bodies in the digestive tract. Background technique [0002] It is the first choice for most patients to take out foreign bodies directly from the oral cavity into the digestive tract without opening an incision. But this approach can also cause harm: [0003] For some flaky foreign bodies such as blades and iron blocks, the existing technology uses a clamp-type device to remove them. Since the device does not have a cutting device, the size of the foreign bodies cannot be reduced, so that the foreign bodies maintain their original size, and there is no protection device for the digestive tract. The blade may be in direct contact with the wall of the digestive tract. Since the blade is hard and sharp, it may cause serious secondary damage to the wall of the digestive tract when it moves in the bent digestive tract durin...
