Embodiment 1

[0032] see Figure 2-3, a device for taking out foreign matter in the digestive tract, comprising an insertion tube 1, a spline shaft 2 is provided in the inner cavity of the insertion tube 1, a mounting plate 6 is fixedly connected to the bottom of the spline shaft 2, and a mounting plate 6 is fixedly connected to the bottom of the mounting plate 6 The ring tooth rack 7 is movably connected with the clamping mechanism 5 on the outer wall of the insertion tube 1 relative to the position of the ring tooth rack 7. The clamping mechanism 5 is provided with three groups, and is evenly distributed on the bottom of the insertion tube 1. The clamping mechanism 5 includes a mounting frame 8, the mounting frame 8 is fixedly connected with the outer wall of the pipe 1, the inner cavity of the mounting frame 8 is movably connected with a toothless gear 9, the toothless gear 9 is meshed with the ring rack 7, and the mounting frame 8 The outer wall is movably connected with a clamp arm 10 ...

Embodiment 2

[0035] see image 3 , is basically the same as the first embodiment, furthermore, the splint 11 is an elastic structure, and the inner wall of the splint 11 is provided with anti-skid lines.

[0036] Improve the stability of clamping by setting anti-skid lines.

[0037] see Figure 4 The side of the mounting frame 8 far away from the clamp arm 10 is provided with an anti-reverse mechanism, the anti-reverse mechanism includes a ratchet 15, and the ratchet 15 is coaxially fixed with the axial center of the tooth-missing gear 9, and the outer wall of the mounting frame 8 is relatively The upper position is fixedly connected with the limiting housing 12, the inner cavity of the limiting housing 12 is slidingly connected with the limiting block 13, the bottom of the limiting block 13 is engaged with the ratchet 15, and the bottom of the limiting block 13 is connected with the bottom of the limiting housing 12. A spring 14 is arranged between the inner walls.

[0038] When the too...

Embodiment 3

[0046] see Figure 7 , is basically the same as Embodiment 2, furthermore, the top of the jet housing 27 is fixedly connected with a jet tube one 32, the bottom of the jet tube one 32 communicates with the inner cavity of the jet housing 27, and the inner wall of the jet tube one 32 slides A piston block 33 is connected, a spring 2 34 is arranged between the top of the piston block 33 and the inner wall of the jet tube 1 32, and the side wall of the jet tube 1 32 near the conduit 31 is fixedly connected with an air guide tube 1 35, an air guide tube 1 35 The end away from the jet tube 1 32 extends to the inner cavity of the conduit 31 , and the outlet position is inclined.

[0047] After the protective fluid in the inner cavity of the liquid storage bag 30 is squeezed out, as the piston plate 28 continues to move to the right, there is still pressure in the inner cavity of the jet housing 27, and when the pressure in the inner cavity of the jet housing 27 is gradually greater ...

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...
