Description

Endoscopic foreign body removal device

Technical Field

The utility model relates to the technical field of medical devices, and in particular to an endoscopic foreign body removal device.

Background Art

Foreign bodies in the upper gastrointestinal tract are one of the common emergencies of the digestive system. The American Guidelines for the Treatment of Foreign Bodies in the Gastrointestinal Tract suggest that 80% to 90% of foreign bodies can be discharged on their own, about 10% to 20% of foreign bodies in the upper gastrointestinal tract require endoscopic removal, and about 1% of foreign bodies require surgical removal. Situations that require timely treatment include: children who have obvious symptoms after swallowing foreign bodies, such as vomiting, drooling, pain, etc. that cause children to cry; those with gastrointestinal lesions, such as esophageal stenosis, anastomotic stenosis after upper gastrointestinal surgery, or tumors that cause stenosis of the lumen; those who swallow sharp or dangerous foreign bodies are prone to complications. With the development of endoscopic technology, endoscopic foreign body removal has the characteristics of being convenient, easy to perform, with few complications and a high success rate, thus avoiding surgical treatment and reducing patient pain, and has become the preferred treatment for foreign bodies in the upper gastrointestinal tract.

At present, during foreign body removal surgery, the gastroscope is advanced until the foreign body is found, and appropriate auxiliary instruments are selected according to the properties and location of the foreign body, and the foreign body is partially grasped and withdrawn together with the gastroscope. For oblate foreign bodies (coins, game coins, button batteries, etc.), appropriate foreign body forceps can be selected according to their thickness; long foreign bodies (chopsticks, metal spoons, pens, etc.) can be grasped on one side with three-claw forceps, foreign body forceps, etc.; however, some relatively round and smooth foreign bodies (spheres or cylinders such as glass beads and magnets) are swallowed or inhaled into the gastric cavity or airway by patients, and it is difficult to grasp such foreign bodies using traditional endoscopic foreign body forceps, snares and other instruments. Therefore, it is very difficult to remove such foreign bodies under endoscopy. If the endoscope cannot remove such foreign bodies in time, the foreign bodies may be retained or enter the lower digestive tract, causing intestinal obstruction, infection or even digestive tract perforation in patients.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

Example

Please refer to Figures 1 to 5. This embodiment provides an endoscopic foreign body removal device, comprising a capture component 1, a connection component 2 and a control component 3; the capture component 1 and the control component 3 are connected to the connection component 2; the capture component 1 comprises a plurality of arc-shaped capture skeletons 5 arranged in sequence, and the plurality of capture skeletons 5 constitute a capture area; the control component 3 controls the capture area to expand or collapse.

In the above embodiment, children will have obvious symptoms after accidentally swallowing foreign objects, such as vomiting, drooling, pain, etc., which may cause the child to cry; those who accidentally swallow sharp or dangerous foreign objects are prone to complications. If children accidentally swallow relatively round and smooth foreign objects (glass beads, magnets, etc., spheres or cylinders) that enter the upper digestive tract, medical personnel can remove the above foreign objects through an endoscopic foreign body removal device. In the present application, the endoscopic foreign body removal device is composed of a capture component 1, a connection component 2 and a control component 3, one end of the connection component 2 is connected to the capture component 1, and the other end of the connection component 2 is connected to the control component 3. The medical staff can control the capture component 1 to capture foreign bodies through the control component 3; specifically, the medical staff needs to first detect the patient's digestive tract, move the endoscope from the patient's mouth to the digestive tract, the endoscope obtains the image in the patient's digestive tract and transmits it to the display for the medical staff to watch, the medical staff moves the endoscope to the foreign body according to the image, and then makes the foreign body removal device enter the lesion through the biopsy channel of the endoscope, the medical staff uses the control component 3 to make multiple capture skeletons 5 expand outward into an "umbrella shape" (after the multiple capture skeletons 5 are expanded, the capture area is expanded), and then the capture area is close to the foreign body. At this time, the medical staff again uses the control component 3 to make the multiple capture skeletons 5 collapse inward into a "sphere" (after the multiple capture skeletons 5 are collapsed, the capture area is collapsed), and the multiple capture skeletons 5 are collapsed to wrap the foreign body inside, and finally the foreign body removal device wrapped with the foreign body is removed from the patient's digestive tract.

In this embodiment, the endoscopic foreign body removal device is suitable for oblate foreign bodies (coins, game coins, button batteries, etc.), sharp foreign bodies (blades, thumbtacks, etc.) and some relatively rounded and smooth foreign bodies (glass beads, magnets and other spheres or cylinders); especially when removing relatively rounded and smooth foreign bodies, the foreign bodies can be firmly wrapped to prevent the foreign bodies from being retained or slipping into the lower digestive tract, causing intestinal obstruction, infection or even digestive tract perforation in patients.

Furthermore, in the present invention, an end of the capture frame 5 away from the connection assembly 2 is connected with an arc-shaped capture member 14 , and an anti-slip layer is provided on the inner side of the capture member 14 .

In this embodiment, if the size of the foreign object is small, the foreign object can be clamped by multiple capture members 14 (to prevent the foreign object from falling off from between two adjacent capture frames 5 when it is wrapped in the capture area). The capture member 14 is made of rubber material. The capture member 14 deforms itself when clamping the foreign object, thereby increasing the contact area and pressure with the foreign object, so that the foreign object can be clamped more firmly. The surface of the capture member 14 that contacts the foreign object is provided with anti-slip grooves, which enhances the anti-slip effect on the foreign object.

Furthermore, in the present invention, a leak-proof component 6 is also included, and a leak-proof component 6 is connected between two adjacent capture skeletons 5 .

In this embodiment, the leakproof member 6 (the leakproof member 6 can be a transparent film) can seal the gap between two adjacent capture skeletons 5. During the work of removing foreign matter, multiple capture skeletons 5 are gathered into a "spherical shape". After the multiple capture skeletons 5 are gathered, the foreign matter is wrapped inside. A leakproof member 6 is arranged between two adjacent capture skeletons 5 to prevent foreign matter from falling from between two adjacent capture skeletons 5, and also to prevent foreign matter with sharp edges from damaging the mucosa of the stomach and esophagus during the removal process.

Furthermore, in the utility model, the connecting component 2 includes an inner sleeve 13 and an outer sleeve 4, the inner sleeve 13 is located inside the outer sleeve 4, and one end of multiple capture skeletons 5 is connected to the inner sleeve 13; the control component 3 includes a base 7, a push rod 10 with a hollow structure, a reset spring 11, a first traction line 19 and a second traction line 20, the base 7 is installed on one end of the outer sleeve 4, the push rod 10 passes through the base 7 and is connected to the inner sleeve 13, the reset spring 11 is sleeved on the push rod 10, one end of the reset spring 11 is connected to the base 7, and the other end of the reset spring 11 is connected to the push rod 10, the capture skeleton 5 is a hollow structure, and a first traction line 19 is arranged in the capture skeleton 5, one end of the first traction line 19 is connected to the capture member 14, and the other ends of multiple first traction lines 19 are all connected to the same second traction line 20, and the second traction line 20 passes through the inner sleeve 13 and the push rod 10 in sequence.

In this embodiment, the connecting component 2 is composed of an inner sleeve 13 and an outer sleeve 4. The inner diameter of the outer sleeve 4 is larger than the outer diameter of the inner sleeve 13. The outer sleeve 4 is flexible and the inner sleeve 13 is elastic. The inner sleeve 13 is used to connect the control component 3 and the capture component 1. Multiple capture skeletons 5 are located at one end of the outer sleeve 4 and are all installed in the inner sleeve 13. A first traction line 19 is provided in each of the multiple capture skeletons 5. One end of the first traction line 19 is connected to the capture member 14, and the other end of the first traction line 19 extends into the inner sleeve 13. Multiple first traction lines 19 converge together in the inner sleeve 13. The outer sleeve 4 is provided with a base 7 at one end away from the plurality of capture frames 5, and the base 7 is provided with a channel adapted to the push rod 10. The push rod 10 passes through the channel and is connected to the inner sleeve 13 (the channel has a certain depth, and the push rod 10 will not swing when it moves relative to the base 7). A reset spring 11 is installed between the push rod 10 and the base 7. Specifically, when the reset spring 11 is reset, the push rod 10 is first pulled away from the base 7, and the push rod 10 drives the inner sleeve 13 to move, and the inner sleeve 13 drives the push rod 10 to move. The multiple capture skeletons 5 are moved into the outer sleeve 4. Since the multiple capture skeletons 5 are elastic, the multiple capture skeletons 5 are squeezed and deformed at the opening of the outer sleeve 4, and finally the multiple capture skeletons 5 enter the outer sleeve 4. When removing foreign bodies from patients, the patient's digestive tract is first detected by endoscopy, and then the foreign body removal device is passed through the biopsy channel of the endoscope to enter the digestive tract. After the foreign body removal device enters the patient's digestive tract through the biopsy channel, the medical staff pushes the push rod 10, and the push rod 10 approaches the base 7. The push rod 10 drives the inner sleeve 13 to move, and the inner sleeve 13 drives the multiple capture skeletons 5. Move, and make most of the multiple capture skeletons 5 exposed from the outer sleeve 4, the multiple arc-shaped capture skeletons 5 form an "umbrella-shaped" capture area, adjust the position of the capture area to make it close to the foreign body, and then the medical staff pulls the second traction line 20, the second traction line 20 pulls the multiple first traction lines 19, the arc-shaped capture skeleton 5 increases the curvature under the pulling of the first traction line 19, and finally the multiple capture skeletons 5 form a "sphere" to wrap the foreign body, the medical staff pulls the foreign body removal device to fix it at the front end of the endoscope, and takes out the foreign body and the foreign body removal device together when withdrawing the endoscope.

Furthermore, in the present invention, a plurality of bending openings 15 are provided on the inner side of the capture frame 5 along the extension direction.

In this embodiment, the capture skeleton 5 with a hollow structure is provided with a plurality of bending openings 15 on the inner side. When the first traction line 19 controls the capture skeleton 5 to bend, the capture skeleton 5 can be fixed to bend inward through the plurality of bending openings 15 and make the bending easier. Medical personnel do not need to apply too much pulling force, thus simplifying the operation difficulty.

Furthermore, the present invention also includes a limiting assembly, which includes a U-shaped limiting member 12 and a plurality of limiting holes 16 provided on the push rod 10, a pulling portion 17 is provided on one side of the limiting member 12, and a limiting portion 18 cooperating with the limiting hole 16 is provided on the other side of the limiting member 12.

In this embodiment, the U-shaped limiting member 12 has a pulling part 17 and a limiting part 18. Medical personnel can hold the pulling part 17 to control the movement of the second traction line 20, and the second traction line 20 controls the movement of the first traction line 19, so that the multiple capture skeletons 5 are deformed. After the multiple capture skeletons 5 are deformed to a preset degree, the limiting part 18 is inserted into the corresponding limiting hole 16 to achieve fixation; further, the second traction line 20 is connected to a limiting rod, the limiting rod is connected to the U-shaped limiting member 12, and the limiting rod passes through the push rod 10, thereby improving the overall stability and avoiding the second traction line 20 from shaking and other problems.

Furthermore, in the present invention, first rings 8 are installed on both sides of the base 7 , and a second ring 9 is installed on the push rod 10 .

In this embodiment, the medical staff can place the index finger and the middle finger into the first ring 8, and then place the thumb into the second ring 9, and can push the push rod 10 by the thumb to operate, which is very convenient.
