An endoscope assembly for endoscopic examination is also disposed on one side of the gripping housing surface. The endoscope assembly includes a connecting hose, a connecting compartment, latches, a movable ball, and a camera. The connecting hose is fixedly disposed on one side of the gripping housing surface, a connecting compartment is fixedly disposed at one end of the connecting hose, and several latches are fixedly disposed at one end of the connecting compartment. A movable ball is movably engaged between the latches, and a camera is fixedly disposed on the surface of the movable ball.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a visual drainage tube assembly and an endoscope. Background Technology

[0002] Visual drainage tube assemblies and endoscopes are essential tools in modern medicine for precise diagnosis and treatment. A visual drainage tube assembly typically consists of a drainage tube, camera, light source, transmission lines, and a display terminal. Its core lies in integrating a miniature camera into the front end of the drainage tube, transmitting real-time images of the body to an external monitor via fiber optic or wireless transmission technology. This allows doctors to directly observe the tissue structure, fluid accumulation, and drainage effect in the drainage area. Endoscopes are inserted into the body through natural cavities (such as the digestive or respiratory tract) or minimally invasive incisions, acquiring images of the body using optical or electronic imaging systems. Modern endoscopes often employ high-definition cameras, narrow-band imaging (NBI), or confocal laser endoscopy (CLE) technology, significantly improving image resolution and diagnostic accuracy.

[0003] Such a visual drainage tube assembly has a much lower imaging effect than an endoscope assembly, but the endoscope is limited by its internal steel wire rope and other structures and cannot install drainage tubes; thus, the visual drainage tube assembly and the endoscope assembly in the existing technology cannot be well integrated.

[0004] However, if the endoscope camera and drainage channel are designed in parallel, the tube diameter is large (≥8mm), which is not suitable for narrow cavities (such as the biliary tract and ventricles in children). If the traditional endoscope and drainage tube are designed separately, two operations are required, which increases the risk of infection and the operation time. Therefore, an improved visual drainage tube assembly and endoscope are needed to address this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a visual drainage tube assembly and an endoscope to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a visual drainage tube assembly and an endoscope, comprising a gripping housing, a grip handle fixedly disposed on one side of the surface of the gripping housing, and an endoscope assembly for endoscopic examination on one side of the surface of the gripping housing. The endoscope assembly includes a connecting hose, a connecting compartment, claws, a movable ball, and a camera. The connecting hose is fixedly disposed on one side of the surface of the gripping housing, a connecting compartment is fixedly disposed at one end of the connecting hose, a plurality of claws are fixedly disposed at one end of the connecting compartment, a movable ball is movably engaged between the claws, a camera is fixedly disposed on the surface of the movable ball, an adjustment mechanism for adjusting the shooting angle of the camera is disposed inside the connecting compartment, and a drainage mechanism for controlling drainage is disposed inside the gripping housing.

[0007] Preferably, the adjustment mechanism includes a fixed plate, a connecting rod, a permanent magnet, a connecting wire, an electromagnet, and a spring. A fixed plate is fixedly installed on one side of the connecting chamber. A connecting rod is fixedly installed on the side of the movable sphere near the fixed plate. A permanent magnet is fixedly installed at one end of the connecting rod. A connecting wire is fixedly installed on one side of the surface of the fixed plate. Electromagnets are fixedly installed around the inner sidewall of the connecting chamber. The connecting wire is electrically connected to four electromagnets in sequence. A spring is fixedly installed between the fixed plate and the permanent magnet. By energizing the electromagnets in the adjustment structure, magnetic force is generated, which attracts the permanent magnet, causing the movable sphere to deflect and thus changing the camera's shooting angle. This device uses magnetic control to tilt the camera. Compared to the traditional method of transmission via steel wire rope, this device can greatly simplify its size, leaving space inside the connecting hose for the drainage hose, thus facilitating drainage. Furthermore, by embedding the drainage hose inside the connecting hose, the diameter of the tube can be significantly reduced, making it easier to insert into the patient's body for convenient use.

[0008] Preferably, a copper tube is fixedly installed on the inner side wall of the connecting compartment. The copper tube in this device can play a certain damping role. Since the movable ball of this device is only fixed by spring tension, the entire movable ball may sway continuously in a small range when vibration occurs. At this time, four electromagnets can be energized simultaneously to generate magnetic force to pull the permanent magnet and make it less likely to sway. At the same time, the copper tube in this device can also play an electromagnetic damping role. When vibration causes the movable ball to tend to move, the magnetic field generated by the permanent magnet will be deflected. In this way, the copper tube will passively cut the magnetic field lines. At this time, an induced current (eddy current) will be generated in the closed copper tube. According to Lenz's law, the magnetic field generated by the induced current will oppose the change of the original magnetic field. That is, the magnetic field generated by the copper tube always opposes the movement of the permanent magnet. This can further prevent the movable ball and camera from shaking due to vibration.

[0009] Preferably, an isolation glass cover is fixedly installed on the surface of the connecting compartment outside the camera, and a supplementary light ring is fixedly installed on the outside of the camera. The isolation glass cover can protect the camera and facilitate the insertion of the device into the patient's stomach, while the light ring outside the camera can provide supplementary lighting, thereby facilitating clear shooting.

[0010] Preferably, the drainage mechanism includes a motor, a conveying chamber, a rotating disk, a squeezing wheel, a pumping hose, and a drainage pipe. A drainage pipe is fixedly installed inside the connecting hose. A motor is fixedly installed on one side of the gripping housing. A conveying chamber is fixedly installed inside the gripping housing. A rotating disk is movably installed in the middle of the inner side of the conveying chamber via a rotating shaft. The power output shaft of the motor is connected to the rotating shaft of the rotating disk. A squeezing wheel is movably installed on the surface of the rotating disk via a rotating shaft. A pumping hose is fixedly engaged with the inner side wall of the conveying chamber. The end of the pumping hose closest to the drainage pipe is fixedly connected to the drainage pipe. This device achieves fluid transport by periodically squeezing and releasing the pumping hose through the squeezing wheel. Its working principle is that the motor drives the rotating disk and squeezing wheel to rotate periodically. When the roller contacts the pumping hose, local pressure causes the cross-sectional area of ​​the pumping hose to shrink, forming a closed fluid chamber, forcing... The fluid inside the chamber moves along the extrusion direction; the instant the roller leaves the pumping hose, the pumping hose quickly returns to its original shape due to its own elasticity, the chamber volume increases sharply, and the internal pressure drops sharply, forming a negative pressure zone. Under the action of the pressure difference, the external fluid is drawn into the pumping hose, filling the void created after the roller is released. This process achieves self-priming through the elastic deformation of the pumping hose, eliminating the need for an additional liquid-priming device, thus achieving the function of drainage. Another advantage of this device is its ease of cleaning. Due to cost considerations, this device cannot be used only once and therefore requires repeated cleaning and disinfection for multiple uses. Cleaning and disinfecting the impeller of a traditional pump body is very troublesome. However, with this device, only the inside of the pumping hose needs cleaning. Each time it is used, only the inner sidewall of the pumping hose needs to be rinsed and disinfected. Thus, this device not only provides excellent drainage but also allows for convenient cleaning, disinfection, and repeated use.

[0011] Preferably, a connecting joint is fixedly provided at the lower end of the grip handle, and the other end of the pumping hose is fixedly connected to the connecting joint. The liquid to be discharged can be drawn in through the pumping hose through the drainage pipe and then discharged through the connecting joint. The connecting joint of this device can be connected to an external storage device.

[0012] Preferably, an air supply pipe is fixedly provided on one side of the grip shell surface. The air supply pipe can conveniently supply air to the inside of the connecting hose, thereby controlling the softness and hardness of the connecting hose so that the connecting hose can be inserted into the target position on the patient's body. The air supply pipe needs to be connected to an external pump body during use.

[0013] Preferably, the gas supply pipe is equipped with a pressure detection device, which can detect the pressure inside the gas supply pipe in real time to prevent excessive pressure.

[0014] Preferably, a control panel is fixedly installed on one side of the upper end of the grip shell, and a control button is fixedly installed on the upper end of the control panel. The control button is electrically connected to the motor and electromagnet. When in use, medical staff use their hands to grip the handle and grip shell to pick up the device, and then their thumb can naturally touch and press the control button. In this way, the motor and electromagnet can be controlled through the control button. Controlling the motor to work can utilize the peristaltic pump for drainage and suction, while controlling the electromagnets to be energized in different directions can generate an attractive force to attract the permanent magnet and cause displacement, thereby driving the camera to deflect the camera angle to improve the endoscopic imaging range of the device. At the same time, the four electromagnets can be controlled by the cross-shaped control button.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention greatly simplifies the size of the device by leaving space inside the connecting hose for the drainage hose, which facilitates drainage work. Furthermore, by embedding the drainage hose inside the connecting hose, the diameter of the tube can be significantly reduced, making it easier to insert into the patient's body for convenient use.

[0017] 2. This invention incorporates damping. Since the movable sphere of this device is only fixed by spring tension, it may sway slightly during vibration. At this time, four electromagnets can be energized simultaneously to generate magnetic force that pulls the permanent magnet, preventing it from swaying. The copper tube in this device also acts as electromagnetic damping. When vibration causes the movable sphere to tend to move, the magnetic field generated by the permanent magnet will deflect, causing the copper tube to passively cut the magnetic field lines. This induces a current (eddy current) in the closed copper tube. According to Lenz's law, the magnetic field generated by the induced current opposes the change in the original magnetic field. Therefore, the magnetic field generated by the copper tube always opposes the movement of the permanent magnet, further preventing swaying of the movable sphere and camera caused by vibration.

[0018] 3. This invention is easy to clean. Due to cost reasons, this device cannot be used once. Therefore, it needs to be cleaned and disinfected repeatedly for multiple uses. If a traditional pump body is used, it is very troublesome to clean and disinfect the impeller part of the pump body. However, the entire pumping device of this device and only the inside of the pumping hose need to be cleaned. Each time it is used, only the inner side wall of the pumping hose needs to be rinsed and disinfected. In this way, this device can not only achieve a good drainage effect, but also be easy to clean, disinfect and reuse.

[0019] 4. The present invention allows for convenient air supply to the connecting hose via an air supply tube, thereby controlling the flexibility of the connecting hose to facilitate insertion into the target position on the patient's body; however, the air supply tube requires an external pump for use.

[0031] 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.

[0032] Please see Figure 1-7 This invention provides a technical solution: a visual drainage tube 20 assembly and an endoscope, including a gripping housing 1, a grip handle 2 fixedly disposed on one side of the surface of the gripping housing 1, and an endoscope assembly for endoscopic examination on one side of the surface of the gripping housing 1. The endoscope assembly includes a connecting hose 3, a connecting chamber 25, claws 4, a movable ball 5, and a camera 6. The connecting hose 3 is fixedly disposed on one side of the surface of the gripping housing 1, a connecting chamber 25 is fixedly disposed at one end of the connecting hose 3, a plurality of claws 4 are fixedly disposed at one end of the connecting chamber 25, a movable ball 5 is movably engaged between the claws 4, a camera 6 is fixedly disposed on the surface of the movable ball 5, an adjustment mechanism for adjusting the shooting angle of the camera 6 is disposed inside the connecting chamber 25, and a drainage mechanism for controlling drainage is disposed inside the gripping housing 1.

[0033] The adjustment mechanism includes a fixed plate 7, a connecting rod 8, a permanent magnet 9, a connecting wire 10, an electromagnet 11, and a spring 12. A fixed plate 7 is fixedly installed on one side of the interior of the connecting chamber 25. A connecting rod 8 is fixedly installed on the side of the movable ball 5 near the fixed plate 7. A permanent magnet is fixedly installed at one end of the connecting rod 8. A connecting wire 10 is fixedly installed on one side of the surface of the fixed plate 7. Electromagnets 11 are fixedly installed around the inner sidewall of the connecting chamber 25. The connecting wire 10 is electrically connected to four electromagnets 11 sequentially. A spring 12 is fixedly installed between the fixed plate 7 and the permanent magnet. By adjusting the electromagnet 11 in the structure to generate magnetic force, the permanent magnet 9 can be attracted, causing the movable ball 5 to deflect, thereby changing the shooting angle of the camera 6. This device uses magnetic control to control the tilt of the camera 6. Compared with the traditional method of transmission by steel wire rope, this device can greatly simplify the size of the device, leaving space inside the connecting hose 3 for the drainage hose, which facilitates the drainage work of this device. Furthermore, by embedding the drainage hose inside the connecting hose 3, the diameter of the tube can be significantly reduced, making it easier to insert into the patient's body for convenient use.

[0034] A copper tube 13 is fixedly installed on the inner side wall of the connecting chamber 25. The copper tube 13 of this device can play a certain damping role. Since the movable ball 5 of this device is only fixed by the spring 12, the entire movable ball 5 may shake continuously in a small range when vibration occurs. At this time, the magnetic force generated by energizing four electromagnets 11 can be used to pull the permanent magnet to make it less likely to shake. At the same time, the copper tube 13 of this device can also play an electromagnetic damping role. When the vibration causes the movable ball 5 to tend to move, the magnetic field generated by the permanent magnet 9 will be deflected. In this way, the copper tube 13 will passively cut the magnetic field lines. At this time, an induced current (eddy current) will be generated in the closed copper tube 13. According to Lenz's law, the magnetic field generated by the induced current will oppose the change of the original magnetic field. That is, the magnetic field generated by the copper tube 13 always opposes the movement of the permanent magnet. This can further prevent the shaking of the movable ball 5 and the camera 6 caused by vibration.

[0035] An isolation glass cover 14 is fixedly installed on the surface of the connecting compartment 25 outside the camera 6, and a supplementary light ring 26 is fixedly installed on the outside of the camera 6. The isolation glass cover 14 can protect the camera 6 and make it easy to insert the device into the patient's stomach, while the light ring outside the camera 6 can provide supplementary light, so that it can be easy to take clear pictures.

[0036] The drainage mechanism includes a motor 15, a conveying chamber 16, a rotating disk 17, a squeezing wheel 18, a pumping hose 19, and a drainage pipe 20. The drainage pipe 20 is fixedly installed inside the connecting hose 3. A motor 15 is fixedly installed on one side of the surface of the gripping housing 1. A conveying chamber 16 is fixedly installed inside the gripping housing 1. A rotating disk 17 is movably installed in the center of the inner side of the conveying chamber 16 via a rotating shaft. The power output shaft of the motor 15 is connected to the rotating shaft of the rotating disk 17. A squeezing roller 18 is movably mounted on the surface of the conveying chamber 16 via a rotating shaft. A pumping hose 19 is fixedly engaged with the inner side wall of the conveying chamber 16. The pumping hose 19 is fixedly connected to the drainage pipe 20 at one end. This device achieves fluid transport by periodically squeezing and releasing the pumping hose 19 through the squeezing roller 18. Its working principle is that the rotating disk 17 and the squeezing roller 18 are driven to rotate periodically by the motor 15. When the roller contacts the pumping hose 19, local pressure causes the pumping hose to be pumped. The cross-sectional area of ​​tube 19 decreases, forming a closed fluid chamber, forcing the fluid inside the chamber to move in the compression direction. The instant the roller leaves the pumping hose 19, the pumping hose 19 quickly returns to its original shape due to its elasticity, causing a sharp increase in the chamber volume and a sudden drop in internal pressure, creating a negative pressure zone. External fluid, under the pressure difference, is drawn into the pumping hose 19, filling the void created by the roller's release. This process achieves self-priming through the elastic deformation of the pumping hose 19, eliminating the need for an additional liquid-priming device, thus achieving a drainage effect. Furthermore, this device offers the advantage of easy cleaning. Due to cost considerations, this device cannot be used only once and requires repeated cleaning and disinfection for multiple uses. Cleaning and disinfecting the impeller of a traditional pump body is very troublesome. However, with this device, only the inside of the pumping hose 19 needs cleaning. Each cleaning only requires rinsing and disinfecting the inner sidewall of the pumping hose 19. Therefore, this device not only provides excellent drainage but also facilitates cleaning, disinfection, and repeated use.

[0037] The lower end of the grip handle 2 is fixedly provided with a connecting joint 21, and the other end of the pumping hose 19 is fixedly connected to the connecting joint 21. The liquid to be discharged can be drawn in through the drainage pipe 20 via the pumping hose 19 and then discharged through the connecting joint 21. The connecting joint 21 of this device can be connected to an external storage device.

[0038] An air supply pipe 22 is fixedly provided on one side of the surface of the grip shell 1. Air can be conveniently supplied to the inside of the connecting hose 3 through the air supply pipe 22, thereby controlling the softness and hardness of the connecting hose 3 so that the connecting hose 3 can be inserted into the target position of the patient's body. However, the air supply pipe 22 needs to be connected to an external pump body when in use.

[0039] The gas supply pipe 22 is equipped with a pressure detection device, which can detect the pressure inside the gas supply pipe 22 in real time to prevent excessive pressure.

[0040] A control panel 23 is fixedly installed on one side of the upper end of the grip shell 1. A control button 24 is fixedly installed on the upper end of the control panel 23. The control button 24 is electrically connected to the motor 15 and the electromagnet 11. When in use, medical staff use their hands to grip the handle 2 and the grip shell 1 to pick up the device. Then, their thumb can naturally touch and press the control button 24. In this way, the motor 15 and the electromagnet 11 can be controlled by the control button 24. Controlling the motor 15 to work can use the peristaltic pump to perform drainage and suction. Controlling the electromagnet 11 to be energized in different directions can generate an attractive force to attract the permanent magnet 9 and cause it to move, thereby driving the camera 6 to deflect the camera angle to improve the endoscopic imaging range of the device. At the same time, the four electromagnets 11 can be controlled by the cross-shaped control button 24.

[0041] Working principle: When using this device, the connecting hose 3 and the connecting chamber 25 can serve as drainage and endoscopy. When the device is in use, the electromagnet 11 is energized to generate magnetic force, which can attract the permanent magnet 9, causing the movable ball 5 to deflect and thus change the shooting angle of the camera 6. This device uses magnetic control to control the tilt of the camera 6. Compared with the traditional method of transmission by steel wire rope, this device can greatly simplify the size of the device, leaving space inside the connecting hose 3 for the drainage hose, which facilitates the drainage work of this device. Furthermore, by embedding the drainage hose inside the connecting hose 3, the diameter of the tube can be significantly reduced, making it easier to insert into the patient's body for use.

[0042] Meanwhile, this device is equipped with damping. Since the movable ball 5 is only fixed by the spring 12, it may sway slightly when vibration occurs. At this time, the four electromagnets 11 can be energized to generate magnetic force to pull the permanent magnet and prevent it from swaying. The copper tube 13 of this device can also play the role of electromagnetic damping. When the vibration causes the movable ball 5 to tend to move, the magnetic field generated by the permanent magnet 9 will be deflected. The copper tube 13 will passively cut the magnetic field lines. At this time, an induced current (eddy current) will be generated in the closed copper tube 13. According to Lenz's law, the magnetic field generated by the induced current will oppose the change of the original magnetic field. That is, the magnetic field generated by the copper tube 13 always opposes the movement of the permanent magnet. This can further prevent the swaying of the movable ball 5 and the camera 6 caused by vibration.

[0043] When it is necessary to drain the accumulated fluid from the patient's body, the motor 15 drives the rotating disk 17 and the squeezing roller 18 to rotate periodically. When the roller contacts the pumping hose 19, the local compression causes the cross-sectional area of ​​the pumping hose 19 to shrink, forming a closed fluid chamber, forcing the fluid in the chamber to move in the squeezing direction. The instant the roller leaves the pumping hose 19, the pumping hose 19 quickly returns to its original shape due to its own elasticity, the volume of the chamber increases sharply, and the internal pressure drops sharply, forming a negative pressure zone. Under the action of the pressure difference, the external fluid is sucked into the pumping hose 19 to fill the void created after the roller is released. This process is facilitated by the elasticity of the pumping hose 19. The device achieves self-priming by deformation, eliminating the need for an additional liquid-priming device, thus effectively draining fluid. Another advantage is its ease of cleaning. Due to cost considerations, this device cannot be used only once and requires repeated cleaning and disinfection. Cleaning and disinfecting the impeller of a traditional pump is very cumbersome. However, with this device, only the inside of the pumping hose 19 needs cleaning. Each time it is used, only the inner sidewall of the pumping hose 19 needs to be rinsed and disinfected. Therefore, this device provides excellent drainage while also being easy to clean, disinfect, and reuse.

[0044] Finally, this device can conveniently supply air to the connecting hose 3 through the air supply pipe 22, thereby controlling the softness and hardness of the connecting hose 3 so that the connecting hose 3 can be easily inserted into the target position on the patient's body; however, the air supply pipe 22 requires an external pump body for use.

[0045] Preferred, such as Figure 8 , Figure 9 , Figure 10As shown, a first balloon 27 and a second balloon 28 are provided at the end of the connecting chamber 25. The second balloon 28 is located near the edge of the isolation glass cover 14. An extended balloon 29 is integrally formed on the first balloon 27 facing the isolation glass cover 14. The extended balloon 29 is fixedly connected to the connecting chamber 25 by a liner 30. In this embodiment, the liner 30 is axially arranged, and there are two liner 30s evenly distributed around the circumference of the connecting chamber 25. Of course, there can also be three, four, or even more liner 30s evenly distributed around the circumference of the connecting chamber 25. The second balloon 28 is fixedly disposed on the outer side of the connecting chamber 25, and the second balloon 28 is located below the extended balloon 29. There are multiple second balloons 28, and the second balloons 28 are disposed in the space between adjacent liner 30s and the space between the extended balloon 29 and the connecting chamber 25. The second balloon 28 is located near the isolation glass cover 14. One end of the device is fixedly provided with an installation plate 31, and a shape memory metal strip 32 is fixedly provided on the installation plate 31. A scraper 33 is fixedly provided at the end of the shape memory metal strip 32. The shape memory metal strip 32 has a rebound force that bends toward the isolation glass cover 14. The scraper 33 has an arc-shaped structure. During the expansion of the second balloon 28, the scraper 33 is always in contact with the isolation glass cover 14. Two air supply pipes are provided inside the connecting chamber 25 to supply air to the first balloon 27, the second balloon 28 and the extended balloon 29. Since the extended balloon 29 is connected to the first balloon 27, one air supply pipe can supply air to the first balloon 27 and the extended balloon 29 at the same time, and the other air supply pipe supplies air to the second balloon 28. The air supply pipes supplying air to and deflating the balloons are existing technologies. Their specific structure and working principle are not the focus of protection of this application, so they will not be described in detail.

[0046] During use, when positioning is required, simply inflate the first balloon 27 to prop it up and press against the inner wall of the cavity for positioning. When cleaning the isolation glass cover 14 is required, the synergistic effect of the first balloon 27 and the extended balloon 29 enables precise control of the expansion direction of the second balloon 28: when the second balloon 28 inflates, the first balloon 27 and the extended balloon 29 form a physical constraint through the circumferentially distributed axial liner 30, forcing the second balloon 28 to expand only in the direction of the isolation glass cover, avoiding lateral deviation. At the same time, the memory metal strip 32 fixed to the front end of the second balloon 28, due to its preset rebound force towards the glass cover, drives the arc-shaped scraper 33 to always be tightly attached to the surface of the glass cover. Combined with the directional expansion thrust of the second balloon 28, a dual effect of elastic pre-tightening and mechanical pushing is formed, allowing the scraper 33 to slide dynamically along the convex curvature, thoroughly removing stains.
