[0002] The multi-directional gastrointestinal fixation device is a medical device, which is mainly used in general surgery. When performing gastrointestinal surgery in general surgery, a gastrointestinal tube is needed. The gastrointestinal tube is used to supply nutrition and gastrointestinal decompression to the patient. The gastrointestinal tube needs to be fixed when in use.

[0003] After searching, the Chinese patent number CN213527034U discloses a multi-directional fixation device for the gastrointestinal tract of general surgery, which relates to the technical field of general surgery, including an arc-shaped fixing plate, both sides of which are fixedly connected with a bandage, the outer surface of each of the bandages is sleeved with a sliding tube, and the end of the bandage away from the arc-shaped fixing plate is fixedly connected to the outer surface of the sliding tube, and the sides of the two sliding tubes away from each other are threaded with screws. The utility model has a reasonable design structure, which can insert the gastrointestinal tube into the interior of the airbag, and the push-pull rod pushes the piston to move, and the piston pushes the air inside the control barrel into the interior of the airbag. The air pressure inside the airbag increases and expands to make its inner circle contact with the surface of the gastrointestinal tube, so that the inner circle of the airbag is fully contacted and fixed with the outer surface of the gastrointestinal tube, which improves the stability of the gastrointestinal tube and prevents the gastrointestinal tube from falling off. At the same time, it will not squeeze the gastrointestinal tube to cause poor connectivity, thereby ensuring the normal use of the gastrointestinal tube.

[0042] The outside of the fourth rotating shaft 23 is fixedly connected with the first gear 18, the outside of the first gear 18 is rotatably connected with the pawl 19, the outside of the pawl 19 is provided with a ratchet 20, the outside of the ratchet 20 is fixedly connected with the third rotating shaft 21, the third rotating shaft 21 and the fourth rotating shaft 23 are rotatably connected, the outside of the third rotating shaft 21 is connected with a belt 22 for transmission, the outside of the belt 22 is connected with a fifth rotating shaft 24 for transmission, the outside of the fifth rotating shaft 24 is fixedly connected with a universal shaft 25, the side of the universal shaft 25 away from the fifth rotating shaft 24 is fixedly connected with the first rotating shaft 13, and the outside of the first rotating shaft 13 is fixedly connected with a second fixed plate 26;

[0043] The outside of the second fixed plate 26 is slidably connected with the second gear 27, the outside of the second gear 27 is meshedly connected with the rack 30, the rack 30 and the slider 31 are fixedly connected, the outside of the second gear 27 is provided with a first slide groove 28, the outside of the first slide groove 28 is slidably connected with the third connecting block 29, the third connecting block 29 and the disk 9 are fixedly connected, the outside of the slider 31 is fixedly connected with the spring 17, the side of the spring 17 away from the slider 31 is fixedly connected to the disk 9, the outside of the disk 9 is fixedly connected with the second rotating shaft 14, the second rotating shaft 14 and the main body 1 are rotatably connected.

[0044] The working principle of the multi-directional fixing device for the gastrointestinal tract proposed by the present invention is that, based on the first embodiment, the motor 2 fixedly installed outside the first fixing block 3 is started to rotate the threaded rod 4 arranged at the output end of the motor 2, and the rotation of the threaded rod 4 can drive the slide plate 5 connected with the external thread to slide on the main body 1, so as to realize the multi-directional fixing of the gastrointestinal tube body 15. When the threaded rod 4 rotates, the fourth rotating shaft 23 fixedly connected outside is driven to rotate, and when the fourth rotating shaft 23 rotates, the first gear 18 fixedly connected outside is driven to rotate;

[0045] The first gear 18 will cause the externally rotatably connected pawl 19 to push the ratchet 20 to rotate, the ratchet 20 will cause the externally fixedly connected third rotating shaft 21 to rotate, the third rotating shaft 21 will cause the externally driven belt 22 to transmit, the belt 22 will cause the externally driven fifth rotating shaft 24 to rotate, the fifth rotating shaft 24 will drive the externally fixed universal shaft 25 to rotate, the universal shaft 25 will cause the externally fixed first rotating shaft 13 to rotate, the universal shaft 25 is convenient for keeping the disk 9 stable when it is slightly tilted, when the first rotating shaft 13 rotates, it can drive the externally fixed second fixed plate 26 to rotate, the second fixed plate 26 will cause the externally slidably connected second gear 27 to rotate, when the second gear 27 rotates, the position of the externally meshed rack 30 will drop;

When the slider 31 descends, the spring 17 fixed to the outside is in a compressed state. When the angle adjustment is completed, the clamping sleeve 33 rises under the elastic action of the spring 17 to re-fix the gastrointestinal tube body 15. When the rack 30 rises and drives the second gear 27 to rotate in the opposite direction, the angle of the gastrointestinal tube body 15 after the adjustment is completed will not be affected due to the action of the ratchet 20 and the pawl 19.

[0047] The second gear 27 is symmetrically provided with a first slide groove 28 on the outside, and the third connecting block 29 slidably connected to the first slide groove 28 is fixedly connected to the disc 9, so as to keep the position of the second gear 27 unchanged and allow the second gear 27 to slide on the second fixed plate 26 when the angle of the disc 9 changes, thereby maintaining the stability of the device and improving the multi-directional fixing effect of the gastrointestinal tube body 15.
