Clamp-type foreign body removal device and method thereof

Abstract

The invention relates to a clamp type foreign matter picking device and a method thereof, and belongs to the technical field of medical instruments. The device comprises a fixing device, an expandingdevice and an image forming device. The fixing device comprises a casing, a first push rod, a second push rod, a telescopic flexible shaft, a main clamp, a first sub clamp and a second sub clamp. Themain clamp includes a first clamp finger and a second clamp finger. The telescopic flexible shaft is disposed in the casing. One end of the first push rod and one end of the second push rod are respectively provided with a flange, and each flange is provided with a sealing ring which forms a movable seal with the cavity inner wall of the casing. The expanding device comprises a net body, a net body drive and a net body limiter. The imaging device includes a camera disposed at the front end of the net body limiter and a display coupled to the camera via a wire. The picking device can fix foreign matters more firmly, the sliding risk is low, and the picking device is suitable to pick the long foreign matters. By means of the net body, the foreign matters cannot damage the wall of the digestive tract, and the operation is safer.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clamp-type foreign body removal device and a method thereof. Background technique [0002] Gastrointestinal foreign bodies are common abdominal emergency foreign bodies, most of which are swallowed, especially in infants and mental illness or suicide attempts. Most of the foreign bodies can be discharged through the anus, but some patients need surgical treatment because of difficulty in foreign body discharge or complications. According to the circumstances, the operation is divided into two cases: one is a non-invasive operation, which uses a guide tube to enter the digestive tract from the mouth to remove the foreign body, and the other is to directly open an incision in the abdominal cavity to remove it. [0003] However, whether it is invasive or non-invasive, it needs to be fixed by a fixation device when taking it out, so that the foreign body can be taken out. ...
