Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a throat and upper digestive tract foreign body removal device and a foreign body removal method thereof. Background Art

[0002] The pharynx is a key part of the human anatomy. It is located at the junction of the head and neck, connecting the nasal cavity, oral cavity, trachea and esophagus. The pharynx is an important intersection of the respiratory system and the digestive system and has multiple physiological functions. The pharynx consists of two parts: the pharynx and the larynx. The pharynx is a common passage for digestion and respiration. It starts from the base of the skull and is connected to the esophagus. It includes three parts: the nasopharynx, the oropharynx and the laryngopharynx. The larynx includes structures such as the vocal cords, trachea and bronchi, and is the entrance and exit of the respiratory system. The structure of the pharynx is complex and has multiple functions such as breathing, swallowing and phonation. The upper digestive tract is part of the human digestive system and is responsible for the intake, digestion and absorption of food. The upper digestive tract starts from the mouth and extends to the duodenum. It is an important place for the human body to digest food. The upper digestive tract refers to the part of the digestive tract above the Treitz ligament, mainly including the mouth, pharynx, esophagus, stomach, duodenum and other organs. These organs work together to complete physiological functions such as food intake, chewing, swallowing, digestion and absorption.

[0003] In daily life, the throat and upper digestive tract are easily stuck by foreign objects, which can cause serious health problems. Small and smooth foreign objects may have little effect on the body, but larger and sharp foreign objects, if not handled in time, will cause certain damage to the digestive tract mucosa, and in severe cases, may cause digestive tract perforation. Long-term entrapment of foreign objects in the upper digestive tract can cause complications such as mucosal perforation, bleeding, injury and infection, and may even be life-threatening. Therefore, when the throat and upper digestive tract are stuck by foreign objects, medical treatment is generally sought in time. The doctor uses the corresponding removal device to remove the foreign objects to prevent continued damage to the throat and digestive tract mucosa and reduce the risk of complications such as perforation, bleeding, and infection.

[0004] In the existing technology for removing foreign bodies from the throat and upper digestive tract, doctors usually observe and perform the foreign body removal process under the illumination of light by using medical forceps. At the same time, there are also some devices on the market that help doctors remove foreign bodies quickly and safely. Some of them are composed of a shell and an internal movement and clamping mechanism. Although these mechanisms reduce the difficulty of clamping foreign bodies, it is difficult to reduce the secondary contact between the foreign body and the throat or upper digestive tract after the clamping work is completed and removed from the throat or upper digestive tract, which may cause secondary damage to the throat or upper digestive tract by the foreign body. Therefore, when removing foreign bodies, doctors also need to pay attention to and adjust the posture of clamping foreign bodies at all times to reduce the possibility of foreign bodies scratching the throat or upper digestive tract. In summary, the present invention proposes a throat and upper digestive tract foreign body removal device and a foreign body removal method thereof, which improves the efficiency of clamping foreign bodies while reducing the possibility of secondary damage to the throat or upper digestive tract caused by foreign bodies during the process of clamping foreign bodies and removing them from the throat or upper digestive tract, thereby improving the safety and efficiency of the foreign body removal process. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a throat and upper digestive tract foreign body removal device and a foreign body removal method thereof, which improves the efficiency of clamping foreign bodies while reducing the possibility of secondary damage to the throat or upper digestive tract caused by foreign bodies during the process of removing the foreign bodies from the throat or upper digestive tract after clamping, thereby improving the safety and efficiency of the foreign body removal process.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: A foreign body removal device for the throat and upper digestive tract, comprising an outer shell, an inner shell nested inside the outer shell, the inner shell and the outer shell slidingly matched, a moving component for pushing the inner shell to slide is provided on the surface of the outer shell, an operating rod is provided inside the inner shell, one end of the operating rod passes through the inner shell and the outer shell in sequence and the connection between the operating rod and the inner shell and the outer shell is all sliding matched, the other end of the operating rod is hinged with a clamping component driven by the operating rod to clamp foreign bodies, a surface of the outer shell close to one end of the clamping component is hinged with a plurality of supporting flaps and the supporting flaps can completely surround the clamping component when in a closed state, the inner walls of the supporting flaps are hinged with a first connecting rod, the middle part of the first connecting rod is hinged with a first hinge seat fixed to one end of the outer shell close to the clamping component, the end of the first connecting rod away from the supporting flap is hinged with a second connecting rod, and the end of the second connecting rod away from the first connecting rod is hinged to the inner shell.

[0007] Principle of the basic solution: The opening and closing of the support flap is controlled by sliding the inner shell. After the support flap reaches the target position, the support flap is controlled to open, and the clamping assembly approaches the foreign object at the same time. Then the clamping assembly is controlled to open and close by the operating lever to clamp the foreign object. After the foreign object is clamped, the inner shell is slid to retract the clamping assembly, and the support flap is closed to wrap the clamping assembly and the clamped foreign object, and then the entire device is taken out to complete the foreign object removal process.

[0008] The above scheme has the following beneficial effects:

[0009] 1. Compared with the prior art, which requires doctors to pay attention to the contact between the foreign body and the throat or the inside of the upper digestive tract and move slowly and pay attention to the position of the foreign body when clamping and removing the foreign body, the present invention, through the opening and closing of the support flap, can not only play a certain supporting and expanding role on the throat or upper digestive tract near the foreign body when clamping the foreign body, so as to facilitate the doctor to operate the clamping assembly to quickly complete the clamping of the foreign body; but also can completely surround the clamping assembly, thereby reducing the accidental damage of the clamping assembly and the foreign body to the surrounding tissues when the device enters and exits the patient's throat or upper digestive tract, thereby improving the efficiency and safety of clamping foreign bodies and reducing the burden on patients.

[0010] 2. This solution is suitable for removing foreign bodies of different sizes and shapes. The clamping assembly can adapt to foreign bodies of different sizes through the opening and closing action of the operating lever. The opening and closing action of the support flap also makes it easier for the device to enter and fix in the target position, thereby improving the applicability of the operation. The design of the sliding and hinged structure also reduces the friction and damage of the device to the inner wall of the throat and upper digestive tract during operation.

[0011] Furthermore, the clamping assembly includes two second hinged seats arranged on one end of the inner shell near the first hinged seat, and the two second hinged seats are symmetrically arranged, two third connecting rods are symmetrically hinged on one end of the operating rod near the second hinged seat, the third connecting rod is hinged to a fourth connecting rod at one end away from the operating rod, the middle part of the fourth connecting rod is hinged on the second hinged seat, the fourth connecting rod is hinged to a clamping claw at one end away from the third connecting rod, the second hinged seat is hinged with a fifth connecting rod, and the end of the fifth connecting rod away from the second hinged seat is respectively connected to the clamping claw.

[0012] Beneficial effects: The clamping assembly is symmetrically arranged. Through the coordinated action of two second hinged seats, two third connecting rods, two fourth connecting rods and two clamping claws, the clamping process is more stable, and the foreign body can be clamped more effectively to prevent it from slipping or being damaged during the removal process. By driving the third connecting rod with the operating rod, the angle between the fourth connecting rod and the clamping claw can be flexibly adjusted, so as to achieve precise control of the clamping force, so that the clamping assembly can adapt to foreign bodies of different sizes and materials, ensuring that no damage is caused to the foreign body or surrounding tissues during the removal process. At the same time, the hinged design of the clamping assembly enables the clamping claw to open and close flexibly to adapt to various complex removal environments, and the hinged connection between the operating rod and the third connecting rod also increases the flexibility of operation, so that the doctor can more accurately control the movement and clamping action of the clamping assembly, so that the doctor can ensure the safe removal of foreign bodies while minimizing the irritation and damage to the patient's throat and upper digestive tract, reducing the patient's pain and discomfort.

[0013] Furthermore, an image collector is embedded in one end of the operating rod close to the clamping claw.

[0014] Beneficial effects: The image collector can capture and transmit images of the surgical site in real time, providing doctors with a clear field of vision. Doctors can accurately determine the location, size and shape of foreign bodies by observing the images, so as to more accurately operate the clamping components for clamping, reducing surgical risks caused by unclear vision or improper operation, and improving the accuracy and success rate of surgery. At the same time, it can help doctors monitor various changes during the operation in real time, such as the movement of foreign bodies, the reaction of surrounding tissues, etc. Once an abnormality is found, the doctor can immediately stop the operation and take appropriate treatment measures to avoid unnecessary damage to the patient.

[0015] Furthermore, a piston is fixedly connected to the operating rod and is slidably matched with the inner wall of the inner shell. The chamber formed by the piston and the inner shell is an inflation chamber, and the outer surface of the support valve is provided with an airbag layer connected to the inflation chamber.

[0016] Beneficial effects: By inflating the inflation cavity, the balloon layer can be expanded to avoid direct contact between the support flap and the inner wall of the throat or upper digestive tract, thereby reducing the risk of wear and damage, protecting the patient's tissue from damage during clamping or expansion, and improving the safety and comfort of treatment; at the same time, it can also increase the contact area and friction between the support flap and the contact surface, improve the stability of clamping or expansion, and make the device less likely to slip or deform during clamping or expansion, ensuring the accuracy and safety of the operation.

[0017] Furthermore, a plurality of teeth are provided on the sides of the two clamping jaws close to each other.

[0018] Beneficial effects: The design of the teeth increases the contact area and friction between the jaws and the foreign body, allowing the jaws to clamp the foreign body more firmly, helping to prevent the foreign body from slipping or moving during the removal process, and improving the stability and safety of the operation. In addition, the teeth can more effectively adapt to the shape and surface features of the foreign body, allowing the jaws to clamp the foreign body more accurately, helping to reduce surgical risks caused by inaccurate clamping and improve the accuracy and success rate of the operation. At the same time, the design of the teeth makes it easier for the jaws to remove the foreign body from the throat or upper digestive tract after clamping it. The teeth can provide additional gripping force, helping doctors or operators to operate the device more easily, reducing surgical time and patient pain.

[0019] Furthermore, the moving component includes a moving through groove which is opened on the surface of the outer shell and away from the supporting petal, and a moving push block which is fixedly connected to the inner shell is arranged inside the moving through groove.

[0020] Beneficial effect: By opening a movable through groove on the surface of the outer shell, the operator can intuitively see and touch the movable push block, and thus conveniently control the movement of the inner shell, the support flap and the clamping claw by pushing or pulling the movable push block, thereby simplifying the operating steps, improving the intuitiveness and convenience of the operation, and enabling the operator to complete the required actions more quickly and accurately.

[0021] Furthermore, the supporting petals are all arc-shaped and when closed, they form a hollow circle at one end away from the operating rod.

[0022] Beneficial effects: The arc-shaped support flaps can better adapt to the shape of the object being clamped or expanded, thereby providing a more uniform and stable clamping or expansion force. When the support flaps are closed, the hollow circles they form can form a continuous, seamless clamping or expansion area, ensuring that the object is firmly clamped or expanded. It also makes it easier for the image collector to collect images of the throat or upper digestive tract when the support flaps are closed.

[0023] Furthermore, all edges of the supporting flap are rounded.

[0024] Beneficial effects: The rounded corners can eliminate the sharp parts of the edge of the support flap, thereby reducing the risk of damage to the clamped or expanded objects and surrounding tissues, reducing irritation and damage to patient tissues during surgery, and improving the safety and comfort of the surgery.

[0025] Furthermore, an auxiliary block is provided at one end of the operating rod away from the supporting flap, and a plurality of auxiliary plates are provided at one end of the housing away from the supporting flap.

[0026] Beneficial effects: The design of the auxiliary block provides doctors with a more stable and comfortable grip point. During the operation, doctors can more easily control the movement and strength of the operating rod, thereby improving the stability and accuracy of the operation. The auxiliary plate can cooperate with the auxiliary block to further provide more support points for doctors to control the movement of the operating rod or the inner shell, thereby enhancing the stability of the operation, making the device more humane and more in line with the doctor's operating habits and needs, thereby improving overall efficiency.

[0027] Furthermore, a method for removing foreign bodies from the throat and upper digestive tract by a foreign body removal device comprises the following steps:

[0028] Step 1: Through observation by an image collector, extend the closed support flap into the patient's throat or upper digestive tract and slowly approach the stuck foreign body;

[0029] Step 2: When the support flap is near the foreign object, the inner shell slides along the outer shell and drives the support flap to open, and the clamping claw approaches the foreign object, and then the operating rod is pulled to open the clamping claw. After reaching the position of the foreign object, the operating rod is pushed to close the clamping claw and clamp the foreign object;

[0030] Step three, after the foreign body is clamped, slide the inner shell so that the clamping claws are close to the outer shell and the supporting flaps are closed and completely surround the clamping claws and the foreign body, and then take out the entire device to complete the foreign body removal process.

[0031] Beneficial effects: Preliminary observation through the image acquisition device ensures that the foreign body and surrounding tissues can be accurately and intuitively seen during the operation, thereby reducing the operational risks. The design of the support flap and the clamping claws can reduce damage to surrounding tissues when clamping foreign bodies, thereby improving the safety of the operation. By sliding the inner shell and pulling / pushing the operating rod, the degree of expansion of the support flap and the opening / closing state of the clamping claws can be flexibly controlled to adapt to foreign bodies of different shapes and sizes, so that doctors can deal with different types of foreign bodies more calmly, thereby improving the efficiency of clamping foreign bodies, reducing the possibility of secondary damage to the throat or upper digestive tract caused by foreign bodies during the process of removing foreign bodies from the throat or upper digestive tract after clamping, and improving the safety and efficiency of the foreign body removal process.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The following is further described in detail through specific implementation methods:

[0043] Embodiment 1:

[0044] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown: a throat and upper digestive tract foreign body removal device, including an outer shell 1, an inner shell 2 is nested inside the outer shell 1, the inner shell 2 and the outer shell 1 are slidably matched, a moving component for pushing the inner shell 2 to slide is provided on the surface of the outer shell 1, an operating rod 6 is provided inside the inner shell 2, and an image collector 17 is embedded in the right end of the operating rod 6 to provide a doctor with a clear view of the patient's throat or upper digestive tract, so that the doctor can accurately judge the position, size and shape of the foreign body by observing the image, so as to more accurately operate the clamping component for clamping, the left end of the operating rod 6 passes through the inner shell 2 and the outer shell 1 in turn, and the connection between the operating rod 6 and the inner shell 2 and the outer shell 1 is all slidably matched, and the right end of the operating rod 6 is hinged with a clamping device driven by the operating rod 6 to clamp the foreign body The surface of the right end of the outer shell 1 is hinged with a plurality of support flaps 10, and the support flaps 10 can completely surround the clamping assembly when they are in a closed state. All edges of the support flaps 10 are rounded to eliminate the sharp parts of the edges of the support flaps 10, reducing the risk of damage to the clamped or expanded object and surrounding tissues. The support flaps 10 are all arc-shaped and the right ends are surrounded by a hollow circle when closed, so as to ensure that when the present invention is inserted into the throat or upper digestive tract of the patient and the support flaps 10 are in a closed state, the image collector 17 can also collect its internal image information through the above hollow circle, which is convenient for the doctor to observe the position between the support flaps 10 and the foreign body in real time, so as to accurately perform subsequent clamping operations, improve efficiency and further enhance safety. The operating rod 6 is integrally formed with a piston 8 that slides with the inner wall of the inner shell 2, and the chamber formed by the piston 8 and the inner shell 2 is an inflation chamber 7. The outer surface of the support flap 10 is bonded with an airbag layer that is connected to the inflation chamber 7.

[0045] The inner wall of the support petal 10 is hinged with a first connecting rod 14, the middle part of the first connecting rod 14 is hinged with a first hinge seat 18 integrally formed at the right end of the outer shell 1, the left end of the first connecting rod 14 is hinged with a second connecting rod 15, and the left end of the second connecting rod 15 is hinged on the inner shell 2.

[0046] The clamping assembly includes two second hinged seats 9 integrally formed at the right end of the inner shell 2, and the two second hinged seats 9 are symmetrically arranged. Two third connecting rods 16 are symmetrically hinged on the right end of the operating rod 6, and the right ends of the third connecting rods 16 are hinged to the fourth connecting rods 13. The middle parts of the fourth connecting rods 13 are respectively hinged on the second hinged seats 9, and the right ends of the fourth connecting rods 13 are hinged to the clamping claws 11. The two clamping claws 11 are each provided with a plurality of teeth 19 on one side close to each other to adapt to the shape and surface characteristics of the foreign matter and to increase the contact area and friction between the clamping claws 11 and the foreign matter, so that the clamping claws 11 can clamp the foreign matter more firmly and accurately, thereby improving the efficiency and safety of the entire foreign matter removal process. The second hinged seats 9 are each hinged with a fifth connecting rod 12, and the right ends of the fifth connecting rods 12 are respectively connected to the clamping claws 11.

[0047] The moving assembly includes a moving through groove which is opened on the surface of the outer shell 1 and is away from the supporting flap 10 , and a moving push block 3 which is integrally formed with the inner shell 2 is arranged inside the moving through groove.

[0048] The left end of the operating rod 6 is integrally formed with an auxiliary block 5, and the left end of the outer shell 1 is integrally formed with a plurality of auxiliary plates 4. In actual operation, the auxiliary block 5 and the auxiliary plates 4 can provide the doctor with more, more stable and more comfortable gripping points, so that during the operation, the doctor can more easily control the movement and strength of the operating rod 6 or the inner shell 2, thereby improving the stability and accuracy of the operation. For example, when the position or strength of the support flap 10 needs to be adjusted quickly, the doctor can rely on the auxiliary block 5 and the auxiliary plate 4 to more quickly adjust the position of the support flap 10 or the inner shell 2.

[0049] The specific implementation process is as follows: First, ensure that the support flap 10 is in a closed state when it is inserted into the patient's throat or upper digestive tract, so as to reduce the damage to the patient's throat or upper digestive tract when the support flap 10 reaches the vicinity of the foreign body. During the movement, the image collector 17 collects real-time internal image information of the throat or upper digestive tract through the hollow circle when the support flap 10 is closed. The doctor can accurately determine the location, size and shape of the foreign body by observing the image, which is convenient for subsequent clamping operations. When the support flap 10 reaches the vicinity of the foreign body, it stops moving, and then the doctor pushes the movable push block 3 to make the inner shell 2 slide along the inner wall of the outer shell 1, thereby driving the second connecting rod 15 hinged to the outer shell 1. Since the second connecting rod 15 is hinged to one end of the first connecting rod 14, and the other end of the first connecting rod 14 is hinged to the inner wall of the support flap 10 and the middle part of the first connecting rod 14 is hinged to the first hinge seat 18, when the inner shell 2 slides along the outer shell 1 toward the clamping jaw 11, the support flap 10 will open to a corresponding degree according to the sliding distance of the inner shell 2. At the same time, due to the friction between the piston 8 and the inner shell 2, when the inner shell 2 slides, it will also drive the clamping jaw 11 to approach the foreign body and extend out of the encirclement of the support flap 10. Then, while limiting the sliding of the inner shell 2, the doctor pulls the operating rod 6 to drive the third connecting rod 16, and the third connecting rod 16 will drive the fourth connecting rod 13 hinged thereto, and the middle part of the fourth connecting rod 13 is hinged on the second hinge seat 9 and the other end is hinged to the clamping jaw 11, and further limiting is performed through the fifth connecting rod 12 hinged on the clamping jaw 11 and the second hinge seat 9, so that during the pulling process of the operating rod 6, a series of connecting rod transmissions are used to separate the distance between the two clamping jaws 11, and then the clamping jaw 11 is brought close to the foreign object, and the operating rod 6 is pushed, and then through the above-mentioned connecting rod transmission, the clamping jaw 11 is closed to complete the clamping of the foreign object. At the same time, when the operating rod 6 is pulled (the clamping jaws 11 are opened), the piston 8 is driven to squeeze the inflation chamber 7 inside the inner shell 2, and the air therein is squeezed into the corresponding airbag layer, which plays a further supporting and protective role; and when the operating rod 6 is pushed (the clamping jaws 11 are closed), the air pressure in the inflation chamber 7 is lower than that in the airbag layer, so that the gas in the airbag layer flows back into the inflation chamber 7, so as to facilitate the subsequent removal of the device.

[0050] After the foreign body is clamped, the push block 3 is slid to return the clamping claw 11 holding the foreign body to its original position, and then the supporting flap 10 is closed through the connecting rod transmission to wrap the clamping claw 11 and the foreign body therein. The doctor then controls the removal speed of the entire device according to the actual situation to complete the removal of foreign bodies in the throat and upper digestive tract.

[0051] Example 2

[0052] The difference from the above embodiment is that a method for removing foreign bodies from the throat and upper digestive tract foreign body removal device comprises the following steps:

[0053] Step 1: Observe the situation in the patient's throat or upper digestive tract through an image acquisition device 17 (such as an endoscope) to determine the location and size of the foreign body, extend the closed support flap 10 (including the clamping claw 11 or other clamping mechanism) into the patient's body through an appropriate path, and slowly and carefully approach the stuck foreign body.

[0054] Step 2: When the support flap 10 reaches the vicinity of the foreign object, the support flap 10 is opened by adjusting the sliding position of the inner shell 2 relative to the outer shell 1 to adapt to the shape and size of the foreign object, and at the same time, the clamping jaw 11 is also driven close to the foreign object. At this time, by pulling the operating rod 6, the clamping jaw 11 is opened to prepare for clamping the foreign object. Once the clamping jaw 11 reaches the foreign object position, by pushing the operating rod 6, the clamping jaw 11 is closed and tightly clamps the foreign object.

[0055] Step three, after confirming that the foreign body is firmly clamped, slide the inner shell 2 to make the jaws 11 and the foreign body close to the outer shell 1. At this time, the support flap 10 closes and completely surrounds the jaws 11 and the foreign body to form a relatively closed space to reduce damage to surrounding tissues. Finally, the entire device (including the support flap 10, the jaws 11 and the foreign body) is removed from the patient's body to complete the foreign body removal process.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
