Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a device for removing foreign bodies from the digestive tract. Background Technology

[0002] Foreign bodies in the digestive tract are substances that are not inherent to the digestive tract and remain in the digestive tract due to various reasons. Foreign bodies in the digestive tract are commonly found in the esophagus and stomach. Clinically, they are usually treated by emergency gastroscopy or even surgery. Some foreign bodies in the digestive tract can be removed by forceps or snares under the guidance of laryngoscopy or gastroscopy.

[0003] During the process of using foreign body forceps to remove foreign objects in the digestive tract, the forceps are first moved inward along the digestive tract. When the foreign object is located, the forceps are pulled outward to drive the pull rope, which clamps and fixes the end of the foreign object. Finally, the foreign object is removed from the digestive tract by pulling outward.

[0004] However, when using foreign body forceps and snares to remove irregularly shaped foreign objects, the existing technology results in a fixed and singular gripping position of the forceps on the digestive tract. If the gripping position of the forceps on the digestive tract is uneven, the gripping effect of the forceps on the foreign object is poor. During the process of moving the forceps outward, the foreign object is prone to falling back into the digestive tract, making it difficult to effectively grasp or fix the foreign object, making removal difficult, and causing secondary damage to the digestive tract itself. Summary of the Invention

[0005] Therefore, the present invention provides a foreign body removal device for the digestive tract, which effectively solves the problems of poor clamping effect of foreign body forceps on foreign bodies in the digestive tract and the easy occurrence of foreign bodies falling back into the digestive tract during the process of moving the foreign body forceps outward.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figure 1 and Figure 2 As shown, the present invention provides a foreign body removal device for the digestive tract, comprising an inlet tube structure 1, an adjustable clamping mechanism 2, an angle adjustment drive structure 3, and a pull rope adjustment structure 4.

[0044] The inlet tube structure 1 is used to drive the adjustable clamping mechanism 2 to be inserted into the patient's body.

[0045] The adjustable gripping mechanism 2 is movably installed at the front end of the inlet tube structure 1. The adjustable gripping mechanism 2 is used to fix the head of the foreign object in the digestive tract and form a retractable gripping space 5 to fix and grip the foreign object as a whole in the digestive tract. The adjustable gripping mechanism 2 can rotate to adjust its gripping angle.

[0046] Angle adjustment drive structure 3 is connected to the adjustable clamping mechanism 2. The angle adjustment drive structure 3 is used to pull one side of the adjustable clamping mechanism 2 so that the adjustable clamping mechanism 2 rotates to one side until the clamping space 5 is directly facing the foreign object in the digestive tract.

[0047] The pull rope adjustment structure 4 is connected to the adjustable clamping mechanism 2. The pull rope adjustment structure 4 is used to pull the structure inside the adjustable clamping mechanism 2 to fix and clamp the foreign object in the digestive tract as a whole, so as to adjust and drive the clamping space 5 to contract inward and make the inner wall of the clamping space 5 form multiple clamping positions to clamp and fix the foreign object in the digestive tract as a whole.

[0048] In this embodiment of the invention, an angle-adjusting drive structure 3 is provided to pull one side of the adjustable clamping mechanism 2, thereby causing the adjustable clamping mechanism 2 to rotate to one side until the clamping space 5 is directly facing the foreign object in the digestive tract. Furthermore, by pulling the structure inside the adjustable clamping mechanism 2 that fixes and clamps the entire foreign object in the digestive tract, the clamping space 5 is adjusted and contracted inward, so that the inner wall of the clamping space 5 forms multiple clamping positions for clamping and fixing the entire foreign object in the digestive tract. This increases the clamping positions for the foreign object in the digestive tract, enhances the clamping effect, and prevents the foreign object from falling back into the digestive tract during the clamping process.

[0049] In this invention, the inlet tube structure 1 is used to drive the adjustable clamping mechanism 2 to be inserted into the patient's body. The inlet tube structure 1 of this invention adopts the following preferred embodiments, such as... Figure 3 As shown, the inlet tube structure 1 includes an inlet tube 11, a cavity 12 disposed within the inlet tube 11, an installation guide rod 13 disposed within the cavity 12, and a rotating connecting seat 14 disposed at the end of the installation guide rod 13.

[0050] In the above embodiment, the adjustable clamping mechanism 2 is mounted on the rotary connecting seat 14. In order to make the direction of the adjustable clamping mechanism 2 adjustable, the rotary connecting seat 14 needs to be rotatably mounted at the end of the mounting guide rod 13. The mounting guide rod 13 is inserted through the inlet tube 11. The adjustable clamping mechanism 2 can follow the rotation angle of the rotary connecting seat 14 to achieve direction adjustment.

[0051] This invention uses an adjustable gripping mechanism 2 to fix the head of a foreign object in the digestive tract and forms a retractable gripping space 5 to fix and grip the entire foreign object in the digestive tract. The adjustable gripping mechanism 2 can rotate to adjust its gripping angle. The adjustable gripping mechanism 2 of this invention mainly adopts the following preferred embodiments, such as... Figure 5 As shown, the adjustable clamping mechanism 2 includes a clamping mounting base 21 disposed on the rotary connecting base 14, a clamping slot seat 22 disposed on the clamping mounting base 21, a telescopic plate 23 disposed in the clamping slot seat 22, and a clamping clamp body 24 rotatably disposed on the telescopic plate 23.

[0052] In the above embodiment, the clamping clamp body 24 is movably mounted on the telescopic plate 23, and the clamping clamp body 24 moves up and down with the telescopic plate 23, while the telescopic plate 23 is slidably mounted in the clamping slot seat 22.

[0053] In addition, in order to grasp the head of the foreign object in the digestive tract from multiple angles, the grasping forceps 24 are set to at least two.

[0054] The clamping clamp body 24 is not in a clamping state in the initial state, and the telescopic plate 23 is also above the clamping slot 22. In order to enable the telescopic plate 23 to perform telescopic movement within the clamping slot 22, a connecting spring 25 is also provided below the telescopic plate 23. The telescopic plate 23 is connected to the bottom of the clamping slot 22 through the connecting spring 25.

[0055] Under the action of the connecting spring 25, the telescopic plate 23 is above the clamping slot 22. When the telescopic plate 23 is pulled down, it moves to the bottom of the clamping slot 22. When the telescopic plate 23 is not pulled down, it returns to its initial position under the action of the connecting spring 25.

[0056] In order to enable the telescopic movement of the telescopic plate 23 to simultaneously drive the adjustment of the clamping state of the clamping structure at the front of the clamping body 24, the present invention also makes the following design: a clamping head 26 is provided on the clamping body 24, the side of the clamping body 26 abuts against the clamping slot seat 22, and the ends of the clamping head 26 and the clamping body 24 away from the connection between the clamping head 26 and the clamping body 24 are away from the inner wall of the clamping slot seat 22.

[0057] As the telescopic plate 23 moves from the top of the clamping slot 22 to the bottom of the clamping slot 22, the sides of the clamping clamp body 26 are squeezed, the clamping clamp body 26 moves inward, and the clamping clamp head 26 retracts inward, so that the clamping clamp head 26 moves closer to each other, thereby realizing the clamping of foreign objects in the middle of the clamping clamp head 26.

[0058] In the above embodiments, the side of the gripping clamp body 26 is always in contact with the side wall of the gripping slot seat 22. In order to ensure that the gripping clamp body 26 can always maintain the above contact state, the present invention also makes the following design: the bottom of the gripping clamp body 24 is rotatably mounted on the telescopic plate 23, the telescopic plate 23 is provided with a connecting seat 27, the gripping clamp body 24 is provided with a connecting shaft 28, the connecting shaft 28 is rotatably mounted on the connecting seat 27, and a torsion spring is provided on the connecting shaft 28. One end of the torsion spring is connected to the connecting shaft 28, and the other end is connected to the connecting seat 27.

[0059] Under the action of the torsion spring, the connecting shaft 28 is always subjected to an outward force, which in turn causes the clamping body 24 to always be subjected to an outward force. Therefore, regardless of whether the telescopic plate 23 causes the clamping body 24 to move up or down, the clamping body 24 always rests against the side wall of the clamping slot seat 22.

[0060] In the above embodiment, the telescopic plate 23 is initially positioned above the gripping slot 22. When the head of the foreign object in the digestive tract is between the gripping jaws 26, the telescopic plate 23 is pulled inward, moving to the bottom of the gripping slot 22. The sides of the gripping jaws 26 are compressed, causing the gripping jaws 26 to move inward and retract, thus bringing the gripping jaws 26 closer together to grip the end of the foreign object in the middle of the gripping jaws 26. When it is necessary to release the gripping force on the foreign object, the tension applied to the telescopic plate 23 is released. Under the action of the connecting spring 25, the telescopic plate 23 returns to its initial position. Under the action of the torsion spring 35, the gripping jaws 26 remain against the inner wall of the gripping slot 22, and the gripping jaws 26 gradually move outward, releasing the gripping of the end of the foreign object in the middle.

[0061] The above structure only grips the end of the foreign object. In order to grip and fix the entire foreign object, the present invention also includes the following design, such as... Figure 5As shown, a gripping claw 29 is rotatably mounted on the gripping mounting base 21. The gripping claw 29 consists of a gripping main plate 291 and at least one gripping secondary plate 292. An adjustment shaft 293 is provided at the end of both the gripping secondary plate 292 and the gripping main plate 291. The gripping secondary plate 292 is rotatably connected to the gripping main plate 291 through the adjustment shaft 293.

[0062] In the above embodiment, the main clamping plate 291 does not perform the clamping function, while the secondary clamping plate 292 performs the clamping function. In order to increase the clamping area with the foreign object, a corresponding sponge clamping pad 294 can be provided on the secondary clamping plate 292. The secondary clamping plate 292 can rotate around the adjustment shaft 293, so that the sponge clamping pad 294 fits more closely and is fixed to the outer wall of the foreign object, thereby enhancing the corresponding clamping effect.

[0063] In order to drive the telescopic plate 23 to slide within the clamping slot seat 22, the present invention is designed as follows: a drive pull rope 210 is provided on the telescopic plate 23, and the drive pull rope 210 passes through the inlet tube 11; the clamping slot seat 22, the rotating connecting seat 14, and the mounting guide rod 13 are all provided with through slots for the drive pull rope 210 to pass through; a drive tube 211 is provided on the inlet tube 11, and a drive threaded bolt 212 is provided on the drive tube 211; a first threaded cylinder 213 is threadedly connected to the drive threaded bolt 212, and the end of the drive pull rope 210 is connected to the first threaded cylinder 213.

[0064] In the above embodiment, the rotating drive tube 211 drives the drive threaded bolt 212. Under the rotation of the drive threaded bolt 212, the first threaded cylinder 213 gradually approaches the drive threaded bolt 212, driving the drive pull rope 210 to pull outward. The drive pull rope 210 pulls the telescopic plate 23 inward, thereby driving the telescopic plate 23 to slide in the clamping slot seat 22.

[0065] In order to enable the angle adjustment drive structure 3 to drive the rotary connecting seat 14 to rotate, the present invention also makes the following design: a sliding groove 214 is provided at the bottom of the rotary connecting seat 14, a sliding block 215 is provided in the sliding groove 214, a telescopic rod 216 is rotatably connected to the sliding block 215, a connecting cavity 217 is provided in the insertion tube 11, and the telescopic rod 216 extends into the connecting cavity 217.

[0066] The telescopic rod 216 can move within the connecting cavity 217. The movement of the telescopic rod 216 causes the sliding block 215 to move, which in turn causes the rotating connecting seat 14 to rotate to one side. During the rotation, the sliding block 215 slides within the sliding groove 214, and the rotating connection between the telescopic rod 216 and the sliding block 215 rotates.

[0067] To facilitate the movement of the telescopic rod 216 within the connecting cavity 217, the present invention provides an angle adjustment drive structure 3. The angle adjustment drive structure 3 of the present invention adopts the following preferred embodiments, such as... Figure 3 and Figure 4 As shown, the angle adjustment drive structure 3 includes a first adjustment rope 31 connected to the telescopic rod 216, a first adjustment tube 32 disposed on the inlet tube 11, a first adjustment threaded bolt 33 disposed on the first adjustment tube 32, and a second threaded cylinder 34 threadedly connected to the first adjustment threaded bolt 33; the end of the first adjustment rope 31 is connected to the end of the second threaded cylinder 34, and the first adjustment rope 31 is disposed through the connecting cavity 217.

[0068] In the above embodiment, rotating the first adjusting tube 32 causes the first adjusting threaded bolt 33 to rotate. Under the rotation of the first adjusting threaded bolt 33, the first threaded cylinder 34 gradually approaches the first adjusting threaded bolt 33, thereby causing the first adjusting pull rope 31 to pull outward. The first adjusting pull rope 31 causes the telescopic rod 216 to move within the connecting cavity 217.

[0069] In order to ensure that the rotating connecting seat 14 can automatically reset when the direction of the adjustable clamping mechanism 2 is not adjusted, the present invention also makes the following design: a reset spring 35 is provided in the connecting cavity 217, and the telescopic rod 216 is connected to the inner wall of the connecting cavity 217 through the reset spring 35.

[0070] Rotate the first adjusting tube 32 to the initial position, causing the first adjusting threaded bolt 33 to rotate. Under the rotation of the first adjusting threaded bolt 33, the first threaded cylinder 34 gradually moves away from the first adjusting threaded bolt 33, thereby causing the first adjusting pull rope 31 to move inward. The first adjusting pull rope 31 reduces the outward pulling distance of the telescopic rod 216. Under the action of the return spring 35, the telescopic rod 216 returns to its original position, so that the rotating connecting seat 14 returns to its initial position.

[0071] This invention utilizes a pull-cord adjustment structure 4 to pull and adjust the clamping mechanism 2 to secure and clamp foreign objects within the digestive tract. This adjusts and causes the clamping space 5 to contract inward, creating multiple clamping positions on the inner wall of the clamping space 5 to hold and fix the foreign object within the digestive tract. The pull-cord adjustment structure 4 of this invention adopts the following preferred embodiments, such as... Figure 3 and Figure 4 As shown, the pull rope adjustment structure 4 includes a second adjustment pull rope 41 connected to the end of the adjustment shaft 293, a connecting cylinder 42 connected to the end of the second adjustment pull rope 41, and a second adjustment threaded bolt 43 connected to the connecting cylinder 42; a second adjustment tube 44 is provided on the second adjustment threaded bolt 43, the second adjustment threaded bolt 43 is fixed on the second adjustment tube 44, the connecting cylinder 42 is threadedly connected to the second adjustment threaded bolt 43, and the second adjustment tube 44 is rotatably mounted on the inlet tube 11; the second adjustment pull rope 41 passes through the clamping mounting base 21 and the inlet tube 11.

[0072] In the above embodiment, rotating the second adjusting tube 44 causes the second adjusting threaded bolt 43 to rotate. Under the rotation of the second adjusting threaded bolt 43, the connecting cylinder 42 gradually approaches the second adjusting threaded bolt 43, causing the second adjusting pull rope 41 to pull outward and the adjusting shaft 293 to move inward, thereby causing the clamping main plate 291 and the clamping secondary plate 292 to rotate inward, clamping and fixing the middle and tail positions of the foreign object.

[0073] In summary, the main implementation process of this invention is as follows:

[0074] Insertion of intubation cannula 11: Insert the intubation cannula 11. The insertion depth of the intubation cannula 11 is determined according to the position of the foreign body in the digestive tract. It is necessary to ensure that the foreign body in the digestive tract is facing or is located on the side of the adjustable gripping mechanism 2.

[0075] Direction adjustment of the adjustable clamping mechanism 2: Rotating the first adjusting tube 32 drives the first adjusting threaded bolt 33 to rotate. Under the rotation of the first adjusting threaded bolt 33, the first threaded cylinder 34 gradually approaches the first adjusting threaded bolt 33, thereby driving the first adjusting pull rope 31 to pull outward. The first adjusting pull rope 31 drives the telescopic rod 216 to move in the connecting cavity 217. The movement of the telescopic rod 216 drives the sliding block 215 to move, thereby driving the rotating connecting seat 14 to rotate to one side, thereby driving the adjustable clamping mechanism 2 to rotate to face the foreign object.

[0076] The head of the foreign object is clamped: the forward-adjustable clamping mechanism 2 is moved forward so that the head of the foreign object is placed between the clamping jaws. The drive tube 211 is rotated to drive the drive threaded bolt 212. Under the rotation of the drive threaded bolt 212, the first threaded cylinder 213 gradually approaches the drive threaded bolt 212, which drives the drive pull rope 210 to pull outward. The drive pull rope 210 pulls the telescopic plate 23 to move inward, thereby moving the telescopic plate 23 to the bottom of the clamping slot seat 22. The side of the clamping jaw body 26 is squeezed. The clamping jaw body 26 moves inward and causes the clamping jaws 26 to retract inward, thereby making the clamping jaws 26 close together to clamp the end of the foreign object in the middle of the clamping jaws 26.

[0077] The body and tail parts of the foreign object are clamped and fixed: the second adjusting tube 44 is rotated to drive the second adjusting threaded bolt 43 to rotate. Under the rotation of the second adjusting threaded bolt 43, the connecting cylinder 42 gradually approaches the second adjusting threaded bolt 43, which drives the second adjusting pull rope 41 to pull outward, and drives the adjusting shaft 293 to move inward, thereby driving the clamping main plate 291 and the clamping secondary plate 292 to rotate inward, clamping and fixing the middle and tail parts of the foreign object;

[0078] Foreign object removal: Reset the first adjusting tube 32 to reset the adjusting clamping mechanism 2, slowly move the inlet tube 11 out, and remove the foreign object. At this time, reset the drive tube 211 and the second adjusting tube 44 to release the clamping force on the foreign object.

[0079] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
