Abstract

The invention discloses a device for taking a foreign body out of the alimentary canal. The device consists of a handle, a plier rod and a plier head sequentially from the back part to the front part, wherein the plier rod consists of an inner core, an inner concentric pipe, a middle pipe and an outer sleeve pipe which are sleeved with one another from the inside to the outside; the plier head consists of a net structure and a protective umbrella; the transparent protective umbrella is sleeved outside the net structure and is made of silica gel and nickel titanium memory alloy; the tail of the protective umbrella is connected with the middle pipe; the tail of the net structure is connected with the inner core; the net structure and the protective umbrella are controlled by the middle pipe and the inner core to be unfolded or folded in the plier rod; and the length of the protective umbrella is more than or equal to the length of the net structure. Through the protective umbrella and the net structure, the foreign body can be taken out safely in time under an endoscope.

Description

technical field [0001] The invention relates to an endoscopic foreign body removal device, in particular to an improved endoscopic foreign body removal device for digestive tract. Background technique [0002] At present, the occurrence of foreign bodies in the digestive tract is relatively common in clinical practice, and it is a common emergency in the Department of Gastroenterology. Usually the foreign matter is smooth, spherical or flat, etc. The characteristics of the foreign matter are: the foreign matter is too large to be clamped directly, and it can only be clamped when it exceeds the diameter of the foreign matter, but smooth or spherical objects are often still will slip. It is easier to scratch the digestive tract when encountering foreign bodies with edges and corners. Therefore, in the limited space of the digestive tract, it is not easy to successfully remove the foreign body through the endoscope. It may take 2 to 6 hours, and surgery may be required if nec...
