Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

Example one

Referring to the accompanying drawings 1-6, the utility model provides a foreign matter takes out apparatus, including handle 1 and clip 2, clip 2 rotates the outside of connecting at handle 1, the inside of handle 1 is provided with connecting rod 9, the one end fixedly connected with threaded rod B13 of connecting rod 9, connecting rod 9 keeps away from threaded rod B13's other end fixedly connected with threaded rod A8, the inside of handle 1 has set up the expanding mechanism who is used for adjusting clip 2, expanding mechanism includes bolt A12, bolt A12 threaded connection is in threaded rod B13's outside, threaded rod A8's outside threaded connection has bolt B5, the externally mounted of clip 2 has protective sheath 3, the outside of protective sheath 3 is provided with emulsion cover 4.

In this embodiment, when using clip 2, at first anticlockwise rotation bolt a12, bolt a12 moves down, bolt a12 drives dead lever 14 anticlockwise rotation, dead lever 14 drives bolt B5 anticlockwise rotation, bolt B5 anticlockwise rotation moves down, sleeve 7 is restricted by two bracing pieces 11 and can not follow bolt B5 and rotate, sleeve 7 follows bolt B5 and moves down, along with bracing piece 11 moves down, the contained angle between bracing piece 11 and sleeve 7 diminishes, when the contained angle between them approaches 0 °, the distance between two clips 2 is minimum, after transferring to minimum distance, stretch into the inside of alimentary canal with handle 1, observe the position of clip 2 and the interior foreign matter of alimentary canal through the gastroscope, after finding suitable position, clockwise rotation bolt a12, bolt a12 moves up, bolt a12 drives dead lever 14 and rotates clockwise, thereby dead lever 14 moves up, fixed lever 14 drives bolt B5 and rotates clockwise, bolt B5 moves up, thereby drive sleeve 7 and move up, the contained angle between sleeve 7 and bracing piece 11, when adjusting the angle that needs to bolt a, stop bolt a clockwise rotation bolt 12 when using, bolt a12 stops clockwise rotation, the interior foreign matter of handle 14 moves up, last 4 that the clamp is inside the latex clip that the clamp is inside, the latex sleeve 2 increases, the last thing that the clamp that the latex is taken out, the interior foreign matter that the latex was increased.
