Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a visual drainage tube assembly and an endoscope. Background Art

[0002] Visual drainage tube assemblies and endoscopes are important tools for precise diagnosis and treatment in modern medicine. Visual drainage tube assemblies are usually composed of a drainage tube, a camera, a light source, a transmission line, and a display terminal. The core of this technology is to integrate a miniature camera into the front end of the drainage tube, and transmit the in vivo images to an external display in real time through optical fiber or wireless transmission technology, so that doctors can visually observe the tissue structure, fluid accumulation, and drainage effect of the drainage area. The endoscope enters the body through the body's natural cavities (such as the digestive tract, respiratory tract) or minimally invasive incisions, and uses optical or electronic imaging systems to obtain in vivo images. Modern endoscopes mostly use high-definition cameras, narrow-band imaging (NBI), or confocal laser microendoscopy (CLE) technology to significantly improve image resolution and diagnostic accuracy.

[0003] The imaging effect of such a visual drainage tube assembly is far inferior to that of an endoscope assembly, but the endoscope is limited by the internal wire rope and other structures and cannot be installed with a drainage tube; thus, the visual drainage tube assembly and the endoscope assembly in the prior art cannot be well combined;

[0004] However, if the endoscope camera and the drainage channel are designed in parallel, the tube diameter will be larger (≥8mm), which is not suitable for narrow cavities (such as children's bile duct and ventricles); if the traditional endoscope and drainage tube are designed separately, two operations are required, increasing the risk of infection and operation time; therefore, to address this problem, an improved visual drainage tube assembly and endoscope are needed. Summary of the Invention

[0005] The object of the present invention is to provide a visual drainage tube assembly and an endoscope to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a visual drainage tube assembly and an endoscope, comprising a holding shell, a holding handle fixedly provided on one side of the surface of the holding shell, an endoscope assembly for endoscopic inspection on one side of the surface of the holding shell, the endoscope assembly comprising a connecting hose, a connecting bin, a clamping claw, a movable sphere, and a camera, a connecting hose fixedly provided on one side of the surface of the holding shell, a connecting bin fixedly provided on one end of the connecting hose, a plurality of clamping claws fixedly provided on one end of the connecting bin, a movable sphere movably engaged between the clamping claws, a camera fixedly provided on the surface of the movable sphere, an adjustment mechanism for adjusting the shooting angle of the camera provided inside the connecting bin, and a drainage mechanism for controlling drainage provided inside the holding shell.

[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 provided on one side of the interior of the connecting chamber, a connecting rod is fixedly provided on the side of the movable sphere close to the fixed plate, a permanent magnet is fixedly provided on one end of the connecting rod, a connecting wire is fixedly provided on one side of the surface of the fixed plate, electromagnets are fixedly provided around the inner side wall of the connecting chamber, the connecting wires are electrically connected to four electromagnets in sequence, and a spring is fixedly provided between the fixed plate and the permanent magnet; magnetic force is generated by energizing the electromagnets in the adjustment structure, so that the permanent magnet can be adsorbed, so that the movable sphere is deflected, thereby changing the shooting angle of the camera, and the present device uses magnetic control to control the tilt of the camera. Compared with the traditional method of transmission through a steel wire rope, the present device can greatly simplify the volume of the device, leaving the space inside the connecting hose for the drainage hose, so that the drainage work of the present device can be facilitated, and the drainage hose is built into the connecting hose, which can significantly reduce the diameter of the pipeline, so that it can be easily inserted into the patient's body for easy use.

[0008] Preferably, a copper tube is fixedly provided on the inner side wall of the connecting bin. The copper tube of the device can play a certain damping role. Since the movable sphere of the device is only fixed by spring pulling, the entire movable sphere may shake continuously in a small range when vibration occurs. At this time, four electromagnets can be energized at the same time to generate magnetic force to pull the permanent magnet so that it is not easy to shake. At the same time, the copper tube of the device can also play the role of electromagnetic damping; when the vibration causes the movable sphere to tend to move, the magnetic field generated by the permanent magnet will be deflected, so the copper tube will passively cut the magnetic lines of force, and 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 hinder the change of the original magnetic field, that is, the magnetic field generated by the copper tube always hinders the movement of the permanent magnet, which can further prevent the shaking of the movable sphere and the camera caused by vibration.

[0009] Preferably, an isolation glass cover is fixedly provided on the surface of the connecting chamber on the outside of the camera, and a fill light ring is fixedly provided 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. The light ring on the outside of the camera can provide fill light, thereby facilitating clear shooting.

[0010] Preferably, the drainage mechanism includes a motor, a delivery bin, a rotating disk, an extrusion wheel, a pumping hose, and a drainage tube, the drainage tube is fixedly provided inside the connecting hose, the motor is fixedly provided on one side of the surface of the gripping shell, the delivery bin is fixedly provided inside the gripping shell, the middle part of the inner side of the delivery bin is movably provided with a rotating disk through a rotating shaft, the power output shaft end of the motor is transmission-connected with the rotating shaft where the rotating disk is located, the surface of the rotating disk is movably provided with an extrusion wheel through a rotating shaft, the inner side wall of the delivery bin is fixedly engaged with a pumping hose, the pumping hose, one end of the pumping hose close to the drainage tube is fixedly connected to the drainage tube, the device realizes fluid delivery by periodically squeezing and releasing the pumping hose through the extrusion wheel, and its working principle is that the motor drives the rotating disk and the extrusion wheel to rotate periodically. When the roller contacts the pumping hose, the local pressure causes the cross-sectional area of ​​the pumping hose to shrink, forming a closed fluid chamber, forcing The fluid in the chamber moves along the extrusion direction; the moment the roller leaves the pumping hose, the pumping hose quickly returns to its original shape by relying on its own elasticity, the chamber volume increases sharply, the internal pressure drops sharply to form a negative pressure area, and the external fluid is sucked into the pumping hose under the action of the pressure difference to fill the space created after the roller is released. This process realizes the self-priming function through the elastic deformation of the pumping hose, and no additional liquid-guiding device is required, which can play a drainage role. At the same time, this device has another advantage when used, that is, it is easy to clean. Due to the cost reasons of this device, it cannot be used once, so it needs to be repeatedly cleaned and disinfected for multiple uses. If a traditional pump body is used for drainage, it is very troublesome to clean and disinfect the impeller part of the pump body. The entire pumping device of this device and only the inside of the pumping hose need to be cleaned. Each time it is cleaned and used, it is only necessary to rinse and disinfect the inner side wall of the pumping hose. In this way, this device can not only play a good drainage effect, but also be easy to clean, disinfect and use repeatedly.

[0011] Preferably, a connecting joint is fixedly provided at the lower end of the holding handle, and the other end of the pumping hose is fixedly connected to the connecting joint. The liquid to be discharged can be sucked into the drainage tube through the pumping hose 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 surface of the gripping shell, through which air can be conveniently supplied to the inside of the connecting hose, thereby controlling the softness and hardness of the connecting hose to facilitate the insertion of the connecting hose into the target position of the patient's body; and the air supply pipe needs to be connected to an external pump body when in use.

[0013] Preferably, a pressure detection device is provided inside the air supply pipe, and the pressure condition inside the air supply pipe can be detected in real time by the pressure detection device to prevent the pressure from being too high.

[0014] Preferably, a control panel is fixedly provided on one side of the upper end of the holding shell, and a control button is fixedly provided on the upper end of the control panel. The control button is electrically connected to the motor and the electromagnet. When in use, the medical staff holds the handle and the holding shell with their hands to pick up the device, and then the thumb can naturally touch and press the control button. In this way, the motor and the electromagnet can be controlled by the control button. The peristaltic pump can be used to control the motor to perform drainage and suction, and the electromagnet can be energized in different directions to generate attraction for adsorbing the permanent magnet to displace, thereby driving the camera to deflect the camera angle to increase the endoscopic shooting range of the device. At the same time, four electromagnets are provided, which can be controlled by the cross-key control button.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention greatly simplifies the volume of the device, leaving the space inside the connecting hose for the drainage hose, thereby facilitating the drainage work of the device, and the drainage hose is built into the connecting hose, which can significantly reduce the diameter of the pipe, thereby making it easy to insert into the patient's body for use.

[0017] 2. The present invention is provided with damping. Since the movable sphere of the device is only fixed by spring pulling, the entire movable sphere may shake continuously in a small range when vibration occurs. At this time, four electromagnets can be energized at the same time to generate magnetic force to pull the permanent magnet so that it is not easy to shake. At the same time, the copper tube of the device can also play the role of electromagnetic damping; when the vibration causes the movable sphere to tend to move, the magnetic field generated by the permanent magnet will be deflected, so the copper tube will passively cut the magnetic lines of force, and 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 hinder the change of the original magnetic field, that is, the magnetic field generated by the copper tube always hinders the movement of the permanent magnet, which can further prevent the shaking of the movable sphere and the camera caused by vibration.

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

[0019] 4. The present invention can conveniently supply air to the interior of the connecting hose through the air supply pipe, thereby controlling the softness and hardness of the connecting hose to facilitate the insertion of the connecting hose into the target position of the patient's body; and the air supply pipe needs to be connected to an external pump body when in use.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-7 The present invention provides a technical solution: a visual drainage tube 20 assembly and an endoscope, comprising a gripping shell 1, a gripping handle 2 being fixedly provided on one side of the surface of the gripping shell 1, an endoscope assembly for endoscopic inspection being provided on one side of the surface of the gripping shell 1, the endoscope assembly comprising a connecting hose 3, a connecting bin 25, a clamping claw 4, a movable sphere 5, and a camera 6, a connecting hose 3 being fixedly provided on one side of the surface of the gripping shell 1, a connecting bin 25 being fixedly provided on one end of the connecting hose 3, a plurality of clamping claws 4 being fixedly provided on one end of the connecting bin 25, a movable sphere 5 being movably engaged between the clamping claws 4, a camera 6 being fixedly provided on the surface of the movable sphere 5, an adjustment mechanism for adjusting the shooting angle of the camera 6 being provided inside the connecting bin 25, and a drainage mechanism for controlling drainage being provided inside the gripping shell 1.

[0033] The adjusting 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 provided on one side of the interior of the connecting chamber 25. A connecting rod 8 is fixedly provided on the side of the movable sphere 5 close to the fixed plate 7. A permanent magnet is fixedly provided on one end of the connecting rod 8. A connecting wire 10 is fixedly provided on one side of the surface of the fixed plate 7. Electromagnets 11 are fixedly provided around the inner side wall of the connecting chamber 25. The connecting wire 10 is electrically connected to the four electromagnets 11 in sequence. A spring 12 is fixedly provided between the fixed plate 7 and the permanent magnet. By energizing the electromagnet 11 in the adjustment structure to generate magnetic force, the permanent magnet 9 can be attracted, thereby causing the movable sphere 5 to deflect, thereby changing the shooting angle of the camera 6. The present device uses magnetic control to control the tilt of the camera 6. Compared with the traditional method of transmission through a steel wire rope, the present device can greatly simplify the volume of the device, leaving the space inside the connecting hose 3 for the drainage hose, thereby facilitating the drainage work of the device. Moreover, the drainage hose is built into the connecting hose 3, which can significantly reduce the diameter of the pipe, thereby facilitating insertion into the patient's body for easy use.

[0034] A copper tube 13 is fixedly provided on the inner side wall of the connecting compartment 25. The copper tube 13 of this device can play a certain damping role. Since the movable sphere 5 of this device is only fixed by pulling by the spring 12, the entire movable sphere 5 may shake continuously in a small range when vibration occurs. At this time, the four electromagnets 11 can be energized at the same time to generate magnetic force to pull the permanent magnet so that it is not easy to shake. At the same time, the copper tube 13 of this device can also play the role of electromagnetic damping; when the vibration causes the movable sphere 5 to have a tendency to move, the magnetic field generated by the permanent magnet 9 will be deflected, so that the copper tube 13 will passively cut the magnetic lines of force. At this time, 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 hinder the change of the original magnetic field, that is, the magnetic field generated by the copper tube 13 always hinders the movement of the permanent magnet, which can further prevent the shaking of the movable sphere 5 and the camera 6 caused by vibration;

[0035] The surface of the connecting chamber 25 is fixedly provided with an isolation glass cover 14 on the outside of the camera 6, and a fill light ring 26 is fixedly provided on the outside of the camera 6. The isolation glass cover 14 can protect the camera 6 and facilitate the insertion of the device into the patient's stomach, while the light ring on the outside of the camera 6 can provide fill light, so that clear pictures can be taken.

[0036] The drainage mechanism includes a motor 15, a delivery bin 16, a rotating disk 17, an extrusion wheel 18, a pumping hose 19, and a drainage tube 20. The drainage tube 20 is fixedly provided inside the connecting hose 3. The motor 15 is fixedly provided on one side of the surface of the grip shell 1. The delivery bin 16 is fixedly provided inside the grip shell 1. The middle part of the inner side of the delivery bin 16 is movably provided with a rotating disk 17 through a rotating shaft. The power output shaft end of the motor 15 is connected to the rotating shaft where the rotating disk 17 is located. The rotating disk The surface of the delivery chamber 16 is provided with an extrusion wheel 18 through a rotating shaft, and the inner side wall of the delivery chamber 16 is fixedly engaged with a pumping hose 19. The pumping hose 19 is fixedly connected to the drainage tube 20 at one end thereof. The device realizes fluid delivery by periodically squeezing and releasing the pumping hose 19 through the extrusion wheel 18. The working principle of the device is that the rotating disk 17 and the extrusion wheel 18 are periodically rotated by the motor 15. When the roller contacts the pumping hose 19, local pressure causes the pumping hose 19 to be pumped. The cross-sectional area of ​​the tube 19 is reduced, forming a closed fluid chamber, forcing the fluid in the chamber to move in the extrusion direction; the moment the roller leaves the pumping hose 19, the pumping hose 19 quickly returns to its original shape by relying on its own elasticity, the chamber volume increases sharply, the internal pressure drops sharply to form a negative pressure area, and the external fluid is sucked into the pumping hose 19 under the action of the pressure difference, filling the space created after the roller is released. This process realizes the self-priming function through the elastic deformation of the pumping hose 19, and no additional liquid-guiding device is required, which can play a drainage role; at the same time, the use of this device has another advantage, that is, it is easy to clean. Due to the cost reasons of this device, it cannot be used once, so it needs to be repeatedly cleaned and disinfected for multiple uses. If a traditional pump body is used for drainage, the cleaning and disinfection of the impeller part of the pump body is very troublesome, while the entire pumping device of the device and only the inside of the pumping hose 19 need to be cleaned. Each time it is cleaned and used, it is only necessary to rinse and disinfect the inner side wall of the pumping hose 19. In this way, the device can not only play a good drainage effect, but also be convenient for cleaning and disinfection and repeated use;

[0037] A connecting joint 21 is fixedly provided at the lower end of the gripping handle 2, and the other end of the pumping hose 19 is fixedly connected to the connecting joint 21. The liquid to be discharged can be sucked in through the drainage tube 20 through the pumping hose 19 and then discharged through the connecting joint 21. The connecting joint 21 of the 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, through which air can be conveniently supplied to the interior of the connecting hose 3, thereby controlling the softness and hardness of the connecting hose 3 to facilitate the insertion of the connecting hose 3 into the target position of the patient's body; and the air supply pipe 22 needs to be connected to an external pump body when in use;

[0039] The air supply pipe 22 is provided with a pressure detection device, which can detect the pressure inside the air supply pipe 22 in real time to prevent the pressure from being too high.

[0040] A control panel 23 is fixedly provided on one side of the upper end of the holding shell 1, and a control button 24 is fixedly provided 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, the medical staff holds the handle 2 and the holding shell 1 with their hands to pick up the device, and then the 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. The peristaltic pump can be used to perform drainage and suction by controlling the operation of the motor 15, and the electromagnet 11 can be energized in different directions to generate attraction for adsorbing the permanent magnet 9 to displace, thereby driving the camera 6 to deflect the camera angle to increase the endoscopic shooting range of the device. At the same time, the electromagnet 11 is provided with four control buttons 24 with a cross key for control.

[0041] Working principle: When using this device, the connecting hose 3 and the connecting chamber 25 of this device can play the role of drainage and endoscopy. When using this device, the electromagnet 11 is energized to generate magnetic force, which can attract the permanent magnet 9, thereby causing the movable sphere 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 through a steel wire rope, this device can greatly simplify the volume of the device, leaving the space inside the connecting hose 3 for the drainage hose, thereby facilitating the drainage work of this device, and the drainage hose is built into the connecting hose 3, which can significantly reduce the diameter of the pipe, so that it can be easily inserted into the patient's body for easy use;

[0042] At the same time, the device is provided with damping when in use. Since the movable sphere 5 of the device is only fixed by pulling by the spring 12, the entire movable sphere 5 may shake continuously in a small range when vibration occurs. At this time, the four electromagnets 11 can be energized at the same time to generate magnetic force to pull the permanent magnet so that it is not easy to shake. At the same time, the copper tube 13 of the device can also play the role of electromagnetic damping; when the vibration causes the movable sphere 5 to have a tendency to move, the magnetic field generated by the permanent magnet 9 will be deflected, so that the copper tube 13 will passively cut the magnetic lines of force. At this time, 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 hinder the change of the original magnetic field, that is, the magnetic field generated by the copper tube 13 always hinders the movement of the permanent magnet, which can further prevent the shaking of the movable sphere 5 and the camera 6 caused by vibration;

[0043] When it is necessary to drain and suck out the accumulated fluid in the patient's body, the motor 15 drives the rotating disk 17 and the squeezing wheel 18 to rotate periodically. When the roller contacts the pumping hose 19, the local pressure 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 along the squeezing direction; the moment the roller leaves the pumping hose 19, the pumping hose 19 quickly returns to its original shape by relying on its own elasticity, the chamber volume increases sharply, the internal pressure drops sharply to form a negative pressure area, and the external fluid is sucked into the pumping hose 19 under the action of the pressure difference to fill the space created after the roller is released. This process is achieved through the elasticity of the pumping hose 19. The deformation realizes the self-priming function, and no additional liquid-guiding device is required, so it can play a drainage role. At the same time, the device has another advantage when used, that is, it is easy to clean. Due to the cost of the device, it cannot be used once, so it needs to be repeatedly cleaned and disinfected for multiple uses. If a traditional pump body is used for drainage, the cleaning and disinfection of the impeller part of the pump body is very troublesome. The entire pumping device and only the inside of the pumping hose 19 of the device need to be cleaned. Each time it is cleaned and used, it is only necessary to rinse and disinfect the inner side wall of the pumping hose 19. In this way, the device can not only play a good drainage effect, but also be easy to clean and disinfect and use repeatedly.

[0044] Finally, the device can conveniently supply air to the inside of the connecting hose 3 through the air supply pipe 22, so as to control the hardness of the connecting hose 3 to facilitate the insertion of the connecting hose 3 into the target position of the patient's body; and the air supply pipe 22 needs to be connected to an external pump body when in use.

[0045] Preferably, 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 provided near the edge of the isolating glass cover 14. The first balloon 27 is integrally provided with an extension balloon 29 facing the isolating glass cover 14. The extension balloon 29 is fixedly connected to the connecting chamber 25 by a lining wall 30. In this embodiment, the lining wall 30 is axially arranged. There are two lining walls 30 uniformly distributed in the circumference of the connecting chamber 25. Of course, there can also be three, four or even more lining walls 30 uniformly distributed in the circumference of the connecting chamber 25. The second balloon 28 is fixedly provided on the outer side surface of the connecting chamber 25. The second balloon 28 is located below the extension balloon 29. There are multiple second balloons 28, and the second balloon 28 is provided in the space between the adjacent lining walls 30 and the extension balloon 29 and the connecting chamber 25; when the second balloon 28 is close to the isolating glass cover 14 A mounting plate 31 is fixedly provided at one end, and a memory metal strip 32 is fixedly provided on the mounting plate 31. A scraper 33 is fixedly provided at the end of the memory metal strip 32. The memory metal strip 32 has a resilience force that bends toward the isolation glass cover 14. The scraper 33 is 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 of the air supply pipes 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 pipe supplying and deflating the balloons belongs to the prior art. Its 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, it is only necessary to inflate the first balloon 27 so that the first balloon 27 is propped up and pressed against the inner wall of the cavity for positioning; when the isolation glass cover 14 needs to be cleaned, the first balloon 27 and the outer balloon 29 work together to achieve precise control of the expansion direction of the second balloon 28: when the second balloon 28 is inflated, the first balloon 27 and the outer balloon 29 form a physical constraint through the circumferentially uniformly distributed axial lining wall 30, forcing the second balloon 28 to expand only in the direction of the isolation glass cover to avoid lateral deviation; at the same time, the memory metal strip 32 fixed at the front end of the second balloon 28 drives the arc-shaped scraper 33 to always closely fit the surface of the glass cover due to its preset rebound force towards 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, so that the scraper 33 slides dynamically along the convex curvature to completely remove stains.
