Digestive tract foreign matter taking-out device

Abstract

The invention discloses a digestive tract foreign matter taking-out device, which comprises a stretching-in pipe. A spline shaft is arranged in an inner cavity of the stretching-in pipe, a mounting plate is fixedly connected to the bottom of the spline shaft, an annular tooth rack is fixedly connected to the bottom of the mounting plate, and a clamping mechanism is movably connected to the position, opposite to the annular tooth rack, of the outer wall of the stretching-in pipe. The three sets of clamping mechanisms are evenly distributed at the bottom of the stretching-in pipe, and each clamping mechanism comprises a mounting frame. Due to the synchronous outward expansion effect of the four sets of arc-shaped plates, the inner wall of the opening air bag is opened and deforms, so that the opening air bag supports the peripheral inner wall of the digestive tract clamped by foreign matter in the digestive tract of a patient, the inner wall of the digestive tract is opened through the opening air bag, the extending height of the extending pipe is limited, and the stability of the extending pipe is improved, and the phenomenon of secondary injury caused by instability when the foreign matter is clamped due to the fact that the stretching-in tube continues to deviate after stretching into the digestive tract is prevented.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical treatment, in particular to a device for taking out foreign bodies in the digestive tract. Background technique [0002] Gastrointestinal foreign bodies are common gastrointestinal emergencies. With the popularization of endoscopy and the maturity of operating techniques, it is safe and simple to remove foreign bodies under gastroscope. has become the treatment of choice. For some sharp foreign bodies embedded in the entrance of the esophagus or next to the aortic arch or in the stomach, if they are not removed promptly and effectively, they will perforate the digestive tract and penetrate into important organs such as arteries or the heart outside the lumen, resulting in perforation, bleeding, infection, etc. Serious complications can even endanger the life of the patient. [0003] Usually, the doctor clamps out the foreign body through the digestive endoscope with foreign body forcep...

AI Technical Summary

Problems solved by technology

[0003] Usually, the doctor clamps out the foreign body through the digestive endoscope with foreign body forceps. Because the process of clamping the foreign body is difficult and the operation time is long, the existing digestive tract foreign body removal device does not have the function of extending the insertion tube to limit the position, and the insertion tube extends into the digestive tract. Finally, it is easy to shift when clamping the foreign body, resulting in instability when clamping the foreign body, causing secondary damage, and bringing great pain to the patient
