Technical Field
[0001] This invention belongs to the field of medical device technology, and in particular relates to a magnetic induction object retrieval device. Background Technology
[0002] The high incidence of urinary system diseases: With population aging and changes in lifestyle, the incidence of urinary system diseases (such as kidney stones, ureteral stones, hydronephrosis, etc.) is increasing year by year. These diseases not only affect patients' daily lives but may also damage kidney function. The widespread use of ureteral stents has effectively alleviated the pain and complications caused by these diseases. Ureteral stent removal surgery generally refers to cystoscopic stent removal. The entire procedure is simple and minimally invasive. The specific steps are as follows: First, the tip of the cystoscope is lubricated and inserted into the urethra to enter the bladder. Forceps are inserted through the cystoscope into the patient's body.

Detailed Implementation
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.
[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0033] This invention provides a magnetic induction object retrieval device, such as... Figure 1-10 As shown, the magnetic induction retrieval device includes: a tube removal system host 1; a tube removal device body 2 connected to the tube removal system host 1 via a data cable 3, the tube removal device body 2 consisting of a handle, a Luer connector 36, a tube body 4, and a sensor head 5, the tube body 4 and the Luer connector 36 being mounted on the handle, the sensor head 5 being mounted at one end of the tube body 4 and used to extract the ureteral stent from the body through the sensor head 5, the sensor head 5 being bent; and a sterilization box 6 installed at the bottom of the tube removal system host 1 for sterilizing the tube removal device body 2.
[0034] In this embodiment, the tube exciter body 2 is connected to the tube excision system host 1 via a data cable 3. The doctor inserts the tube body 4 (the end with the sensor head 5) into the patient's body, facing the position of the ureteral stent. By turning the handle, the doctor can change the direction of the tube body 4 to more accurately position the sensor head 5 near the ureteral stent. The sensor head 5 is designed to attract the ureteral stent. Once the head contacts and attracts the stent, the sensor will send a signal to the tube excision system host 1.
[0035] The operating screen of the main unit 1 of the tube removal system will display the attraction status between the sensor and the ureteral stent, providing real-time feedback to the doctor. Based on the information on the screen, the doctor will slowly pull the tube 4 outward to remove the ureteral stent from the body through the sensor head 5.
[0036] After the tube is removed, the tube remover body 2 is placed in the sterilization box 6 for sterilization and disinfection for future use. The sensor head 5 is bent, which helps to better locate and attract the ureteral stent in the complex internal environment. The sensor provides real-time feedback on the attraction between the tube remover and the ureteral stent, allowing doctors to more accurately judge the timing and force of tube removal, reduce operational errors, and improve surgical safety. Compared with traditional cystoscopic tube removal, this system uses the sensor head 5 to attract the stent, eliminating the need for direct clamping of the stent, reducing trauma and pain during the operation, and improving patient comfort. At the same time, doctors only need to turn the handle to adjust the direction of the tube body 4 and observe the feedback on the operation screen to perform the tube removal operation, reducing the difficulty and complexity of the operation. The tube remover body 2 can be placed in the sterilization box 6 for sterilization and disinfection, ensuring the hygiene and safety of the surgical instruments and reducing the risk of cross-infection.
[0037] In a further preferred embodiment of the present invention, a switch 7 and a protective sleeve 8 are respectively provided on both sides of the host 1 of the tube removal system. The protective sleeve 8 is used to protect the plug interface that is compatible with the data cable 3. A battery cover 9 is provided on the back of the host 1 of the tube removal system.
[0038] In this embodiment, before performing surgery, the doctor needs to turn on switch 7 to start the tube removal system host 1 for subsequent operations and monitoring. When the data cable 3 is not inserted into the tube removal system host 1, the protective sleeve 8 covers the connector to prevent dust, moisture, and other impurities from entering the connector and causing poor contact or damage. The back of the tube removal system host 1 has a battery cover 9 for installing and replacing the battery. The tube removal system host 1 requires battery power to ensure its normal operation. When the battery power is low, the doctor can open the battery cover 9, remove the old battery, and replace it with a new one to ensure the smooth progress of the surgery.
[0039] In a further preferred embodiment of the present invention, a disinfection mechanism is provided inside the disinfection box 6. The disinfection mechanism includes: a mounting plate 10 slidably disposed inside the disinfection box 6, the mounting plate 10 having an annular opening; an annular drain pipe 11 fixedly installed inside the annular opening for rinsing the pipe body 4 and the sensor magnetic head 5; an annular cleaning brush 12 disposed on one side of the mounting plate 10 for washing the pipe body 4 and the sensor magnetic head 5; an ultraviolet disinfection lamp 13 fixedly installed on the top of the inner wall of the disinfection box 6; and a driving mechanism disposed inside the disinfection box 6 for driving the mounting plate 10 to move.
[0040] In this embodiment, when the exciter body 2 is placed into the disinfection chamber 6 and passes through the annular opening, the annular drain pipe 11 can spray disinfectant or clean water to initially rinse the tube body 4 and sensor head 5, removing residual dirt and bloodstains. The annular cleaning brush 12 is made of soft material, such as sponge or rubber, to ensure that it will not damage the tube body 4 and sensor head 5 during the washing process. When the mounting plate 10 moves, the annular cleaning brush 12 will contact and scrub the tube body 4 and sensor head 5 to further remove dirt. Ultraviolet disinfection is an effective sterilization method that can destroy the DNA structure of bacteria, thereby achieving the purpose of sterilization. When the exciter body 2 is placed into the disinfection chamber 6 and exposed to the ultraviolet disinfection lamp 13, the ultraviolet light will penetrate the gaps between the tube body 4 and sensor head 5 to thoroughly disinfect the inside. Through the rinsing of the annular drain pipe 11 and the scrubbing of the annular cleaning brush 12, dirt and bloodstains on the exciter body 2 (especially the tube body 4 and sensor head 5) can be thoroughly removed, providing a good foundation for subsequent ultraviolet disinfection. The irradiation of the ultraviolet disinfection lamp 13 can further kill bacteria and ensure the hygiene and safety of the tube puller body 2. The design of the drive mechanism allows the mounting plate 10 to move automatically, thereby driving the annular drain pipe 11 and the annular cleaning brush 12 to rinse and scrub the tube puller body 2. This reduces the difficulty and complexity of manual operation and improves the automation of the disinfection process.
[0041] In a further preferred embodiment of the present invention, the driving mechanism includes: a one-way screw 14 rotatably installed inside the disinfection box 6, the one-way screw 14 being threadedly connected to the mounting plate 10; a small motor 15 fixedly installed on one side of the disinfection box 6, the output shaft of the small motor 15 being fixedly connected to the one-way screw 14; and a guide rod 16 fixedly installed inside the disinfection box 6 for guiding the mounting plate 10, the guide rod 16 being slidably connected to the mounting plate 10.
[0042] In this embodiment, when the small motor 15 rotates at a constant speed, the one-way screw 14 will rotate at a constant speed. Since the one-way screw 14 is threadedly connected to the mounting plate 10, the mounting plate 10 will move left and right in the disinfection box 6 at a constant speed. The movement of the mounting plate 10 will drive the annular drain pipe 11 and the annular cleaning brush 12 to rinse and clean the pipe body 4 and the sensor magnetic head 5. Since the movement of the mounting plate 10 is uniform, the rinsing and brushing of the pipe body 4 and sensor head 5 by the annular drain pipe 11 and the annular cleaning brush 12 is also uniform. Uniform rinsing and brushing ensures that dirt and bloodstains on the pipe body 4 and sensor head 5 are removed evenly, avoiding the problem of incomplete or over-cleaning caused by uneven speed. The design of the guide rod 16 ensures that the mounting plate 10 maintains stability and linear movement during movement, avoiding the problem of uneven rinsing and brushing or damage to the equipment caused by shaking or tilting. The small motor 15 rotates at a constant speed, reducing energy consumption and noise generation, making the entire disinfection process more energy-efficient and environmentally friendly.
[0043] In a further preferred embodiment of the present invention, an inclined plate 25 is fixedly installed on the bottom of the inner wall of the disinfection box 6, and a reflector 26 for reflecting ultraviolet rays is installed on the inclined plate 25. An annular groove is opened on one side of the mounting plate 10, and an annular limiting plate 32 is fixedly installed on one side of the annular cleaning brush 12. The annular limiting plate 32 is connected to the annular groove.
[0044] In this embodiment, the surface of the reflector 26 is specially treated to efficiently reflect ultraviolet rays, allowing the ultraviolet rays to penetrate deeper into the gaps and hard-to-reach areas of the tube puller body 2, thereby achieving all-round disinfection of the exterior of the tube puller body 2. The design of the annular limiting plate 32 restricts the movement range of the annular cleaning brush 12 on the mounting plate 10, ensuring that the annular cleaning brush 12 always maintains contact with the tube body 4 and the sensor magnetic head 5 during the washing process, thus improving the washing effect. Through the combination of the inclined plate 25 and the reflector 26, the ultraviolet rays can penetrate deeper into the gaps and hard-to-reach areas of the tube puller body 2, thereby improving the ultraviolet disinfection effect.
[0045] In a further preferred embodiment of the present invention, a water tank 17 is installed on the disinfection box 6. The water tank 17 is L-shaped and covers the left side and bottom of the disinfection box 6. A micro water pump 18 is installed inside the water tank 17. A connecting pipe 19 is installed on the output end of the micro water pump 18. The connecting pipe 19 passes through one side of the disinfection box 6 and is fixedly connected to the annular drain pipe 11. A set of guide rollers 20 for guiding the connecting pipe 19 is fixedly installed on one side of the disinfection box 6. The set of guide rollers 20 is located inside the water tank 17.
[0046] In this embodiment, when the micro water pump 18 is started, liquid enters the annular drain pipe 11 through the connecting pipe 19 and is sprayed out from the nozzle of the annular drain pipe 11 to rinse the pipe body 4 and the sensor head 5. The guide roller 20 is used to guide the connecting pipe 19 to maintain a certain degree of curvature and stability within the water tank 17. The micro water pump 18 pumps the liquid in the water tank 17 into the annular drain pipe 11, achieving rapid rinsing of the pipe body 4 and the sensor head 5. This greatly improves rinsing efficiency and shortens disinfection time.
[0047] The micro water pump 18 is started and stopped by the control system, which further saves water resources. The design of the guide roller 20 ensures that the connecting pipe 19 maintains a certain degree of curvature and stability in the water tank 17, avoiding damage or leakage caused by excessive bending of the connecting pipe 19. This enhances the stability and reliability of the equipment. The water tank 17 is L-shaped and wraps around the left side and bottom of the disinfection box 6, making the layout of the entire disinfection system more compact and reasonable, thus effectively saving space.
[0048] In a further preferred embodiment of the present invention, a rotating rod 21 is rotatably mounted on one side of the mounting plate 10. A first bevel gear 22 is fixedly sleeved on one end of the rotating rod 21 and on the annular cleaning brush 12. The two first bevel gears 22 mesh with each other. A drive gear 23 is fixedly sleeved on the other end of the rotating rod 21. A rack 24 is fixedly mounted on one side of the inner wall of the disinfection box 6. The rack 24 meshes with the drive gear 23.
[0049] In this embodiment, when the mounting plate 10 slides inside the disinfection box 6, the driving gear 23 rotates along the rack 24 due to the meshing of the driving gear 23 and the rack 24. Since the driving gear 23 is fixedly connected to the rotating rod 21, the rotating rod 21 also rotates synchronously. The rotation of the rotating rod 21 drives the annular cleaning brush 12 to rotate through the meshing of the first bevel gear 22, thereby realizing the cleaning operation of the annular cleaning brush 12 on the tube body 4 and the sensor magnetic head 5. Through the rotation of the annular cleaning brush 12, dirt and bloodstains on the tube body 4 and the sensor magnetic head 5 can be removed more effectively, improving the cleaning effect. Through the meshing of the gear and rack, the synchronous rotation of the annular cleaning brush 12 is realized when the mounting plate 10 slides, without the need for an additional drive device, thus improving the automation level of the equipment.
[0050] In a further preferred embodiment of the present invention, an operation port is provided on one side of the disinfection box 6, and a cover plate 33 is hinged inside the operation port. A sealing ring for sealing the connection gap between the cover plate 33 and the operation port is fitted on the cover plate 33.
[0051] In this embodiment, when it is necessary to pick up or place the extubator body 2, medical personnel open the cover 33 and operate through the operating port. After the operation is completed, the cover 33 is closed, and the sealing ring will fit tightly against the connection between the operating port and the cover 33, forming an effective seal to prevent external contaminants from entering the disinfection box 6. By adding the sealing ring, it can be ensured that when the cover 33 is closed, there will be no leakage at the connection between the operating port and the cover 33, thereby improving the sealing performance of the disinfection box 6. Through the combination of the cover 33 and the sealing ring, external contaminants can be effectively prevented from entering the disinfection box 6, ensuring the purity and safety of the disinfection process, and also preventing the disinfectant solution from overflowing from the operating port after use.
[0052] In a further preferred embodiment of the present invention, a transparent bracket 37 for supporting the tube puller body 2 is fixedly installed on the bottom of the inner wall of the disinfection box 6, and a connecting plate 34 is fixedly installed on one side of the cover plate 33. The bottom of the connecting plate 34 is inclined, and the connecting plate 34 is located above the body of the tube puller body 2.
[0053] In this embodiment, when cleaning and disinfecting the tube extractor body 2 using the disinfection box 6, the tube extractor body 2 is first placed on the transparent bracket 37, and then the cover 33 is closed. At this time, the connecting plate 34 will be located above the tube extractor body 2 and limit its movement. During the cleaning and disinfection process, the transparent bracket 37 and the connecting plate 34 together ensure the stability and safety of the tube extractor body 2, preventing it from falling or moving. Through the combined design of the transparent bracket 37 and the connecting plate 34, the tube extractor body 2 remains stable during the cleaning and disinfection process and will not fall off the transparent bracket 37, ensuring the cleaning and disinfection effect. The inclined design of the connecting plate 34 can effectively limit the movement of the tube extractor body 2.
[0054] In a further preferred embodiment of the present invention, a locking block 35 is rotatably installed on one side of the disinfection box 6, and the locking block 35 is rotatably in contact with one side of the cover plate 33. Two baffles for limiting the sliding length of the mounting plate 10 are fixedly sleeved on the one-way screw 14.
[0055] In this embodiment, when it is necessary to close the cover 33, the user pushes the cover 33 toward the disinfection box 6 until one side of the cover 33 rotates into contact with the locking block 35. At this time, the locking block 35 provides resistance, making it difficult for the cover 33 to be opened, thereby locking the cover 33. During the sliding process of the mounting plate 10, the baffle rotates together with the one-way screw 14. When the mounting plate 10 slides to the predetermined position, the baffle limits the mounting plate 10, thereby preventing the mounting plate 10 from continuing to slide. In this way, the baffle plays a limiting role, ensuring that the sliding length of the mounting plate 10 is within the predetermined range. The addition of the locking block 35 and the baffle improves the stability of the disinfection box 6 and the mounting plate 10. The locking block 35 ensures the stability of the cover 33 when closed, while the baffle prevents the mounting plate 10 from exceeding the predetermined range during sliding. The locking mechanism of the locking block 35 prevents the cover 33 from being accidentally opened, thus avoiding potential contamination and danger. The limiting function of the baffle ensures that the mounting plate 10 will not collide with other components inside the disinfection chamber 6 during sliding, guaranteeing the safety of the equipment.
[0056] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:
[0057] In another embodiment of the present invention, one end of the one-way screw 14 extends into the water tank 17, and a connecting rod 27 is rotatably installed on one side of the disinfection box 6. A second bevel gear 28 is fixedly sleeved on one end of both the connecting rod 27 and the one-way screw 14. The two second bevel gears 28 mesh with each other. A sprocket 29 is fixedly sleeved on both the connecting rod 27 and any one of the guide rollers 20. A chain 30 is sleeved on the two sprockets 29. The chain 30 meshes with the two sprockets 29.
[0058] In this embodiment, when the one-way screw 14 rotates under the drive of the small motor 15, it will drive the second bevel gear 28 fixedly sleeved with it to rotate. The rotating second bevel gear 28 will drive another second bevel gear 28 meshing with it to rotate, thereby driving the connecting rod 27 to rotate. The rotating connecting rod 27 will drive the guide roller 20 connected to it to rotate through the meshing action of the sprocket 29 and the chain 30.
[0059] When the mounting plate 10 slides closer to the micro water pump 18 under the drive of the one-way screw 14, the rotation of the guide roller 20 will move a section of the connecting pipe 19 into the water tank 17 so that the micro water pump 18 can draw disinfectant from the water tank 17. When the mounting plate 10 slides away from the micro water pump 18, the guide roller 20 will continue to rotate due to the meshing of the chain 30 and the sprocket 29, thereby releasing the connecting pipe 19 and allowing it to slide into the disinfection box 6 through the notch on one side of the disinfection box 6, ensuring a stable connection between the annular drain pipe 11 and the connecting pipe 19. By adding components such as the connecting rod 27, the second bevel gear 28, the sprocket 29, and the chain 30, the one-way screw 14 can drive the mounting plate 10 to slide while also driving the guide roller 20 to rotate, thereby realizing the automatic entry and exit control of the connecting pipe 19 and effectively improving the automation level of the equipment.
[0060] In another embodiment of the present invention, a connecting gear 31 is fixedly sleeved on the output rod of a group of guide rollers 20, and two connecting gears 31 mesh with each other. An anti-slip pad is sleeved on a group of guide rollers 20.
[0061] In this embodiment, when the unidirectional screw 14 rotates and drives the guide roller 20 (referred to as the "driving roller") connected to it to rotate, the connecting gear 31 on the driving roller will rotate accordingly. The rotating connecting gear 31 will drive the connecting gear 31 on the other guide roller 20 (referred to as the "driven roller") to rotate through meshing, thereby driving the driven roller to rotate synchronously. In this way, the two guide rollers 20 achieve synchronous rotation, so that the entry and exit of the connecting pipe 19 can be controlled synchronously.
[0062] The anti-slip pad increases the friction between the guide roller 20 and the connecting pipe 19, thereby improving the stability and accuracy of the guide. At the same time, the anti-slip pad can also reduce the wear between the guide roller 20 and the connecting pipe 19 to a certain extent.
[0063] In summary, compared with related technologies, this tube removal system allows for adjustment of the tube bend direction by rotating the tube removal handle, and the screen of the main unit displays whether the tip of the tube removal device has adhered to the ureteral stent, which can intuitively assist doctors in completing the surgery.
[0064] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the invention.
