Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an adjustable endoscope probe for pediatric gastrointestinal examinations. Background Art

[0002] In the field of pediatric medicine, gastrointestinal examinations are one of the important means for diagnosing children's digestive system diseases. Traditional gastrointestinal examination equipment, such as endoscopes, although can meet clinical needs to a certain extent, still has many deficiencies in the actual operation process. Especially for pediatric patients, these problems are particularly prominent.

[0003] First of all, most of the existing endoscope probes adopt a fixed design, and the orientation of their cameras cannot be flexibly adjusted. During gastrointestinal examinations, doctors often need to insert and remove the probe multiple times to obtain observation images from different angles, which not only increases the operation difficulty and time cost of the examination, but also may bring additional pain and discomfort to pediatric patients. Especially when examining complex structures or hidden parts, the fixed-orientation camera often fails to meet the comprehensive and detailed observation requirements.

[0004] Secondly, during the use of the endoscope probe, its lens is easily contaminated by the liquid, secretions or food residues in the digestive tract, resulting in a decrease in image clarity and affecting the doctor's diagnostic judgment. For pediatric patients, due to their relatively narrow and sensitive digestive tracts, the situation of lens contamination is more likely to occur.

[0005] Finally, pediatric patients are more sensitive to temperature. When the cold endoscope probe is inserted into the digestive tract, it is extremely likely to cause fear, nervousness and discomfort in the patient, and may even lead to non-cooperation or interruption during the examination. The existing endoscope probes lack a structure for temperature adjustment and cannot be preheated or adjusted according to the actual needs of the patient, thus limiting their application in pediatric gastrointestinal examinations. Summary of the Invention

[0006] The purpose of the present invention is to provide an adjustable endoscope probe for pediatric gastrointestinal examinations, which can preheat the endoscope probe part before gastrointestinal examinations and enter the patient's body at a relatively comfortable temperature to reduce discomfort. During the examination, it can adjust the orientation of the camera part on the side of the probe according to the needs to closely observe the states of different positions in different parts of the digestive tract, and can also wipe the camera part to prevent body fluids and residues in the digestive tract from covering the camera part and affecting the examination.

[0026] The probe assembly and regulation assembly of the present invention can wipe the imaging part according to requirements during the examination, so as to avoid the body fluids and residues in the digestive tract covering the imaging part and affecting the examination; during the examination process, if the imaging part on the side of the endoscope probe is covered and the shooting is unclear, by reversely rotating the rotation part of the holding assembly, the whole of the shooting assembly rotates reversely. At this time, the limiting part of the positioning assembly will fix the outer shell of the shooting assembly, and only let the inner ring part of the shooting assembly rotate, so that the shooting part of the shooting assembly will continuously rub the inner wall of its outer shell part for wiping. After the examination is completed, the outer shell of the shooting part can be removed for cleaning to avoid affecting subsequent examinations. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0047] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present invention. The "in a preferred embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0048] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions of length, width and depth should be included.

[0049] Please refer to the attached Figures 1 to 15 As shown, this embodiment provides an adjustable endoscope probe for pediatric digestive tract examination, including a main body assembly 10. The main body assembly 10 includes a holding assembly 11, and a hose 12 is fixedly connected below the holding assembly 11;

[0050] A probe assembly 20, the probe assembly 20 includes a long tube assembly 21 provided at the bottom end of the hose 12, a photographing assembly 22 is provided at the bottom end of the long tube assembly 21, and a positioning assembly 23 is provided in the inner cavity of the photographing assembly 22;

[0051] A regulation assembly 30, the regulation assembly 30 includes an energy supply assembly 31 provided in the inner cavity of the long tube assembly 21, and a driving assembly 32 is provided below the energy supply assembly 31;

[0052] Among them, before the digestive tract examination, the long tube assembly 21 is connected to hot water to preheat the probe. After the long tube assembly 21 and the hose 12 enter the patient's body, the photographing assembly 22 is used to photograph the situation inside the digestive tract;

[0053] The photographing assembly 22 is divided into two states. In the first state: the driving assembly 32 drives the energy supply assembly 31 to rotate forward along the inner cavity of the long tube assembly 21, and then drives the photographing assembly 22 to rotate forward to adjust the orientation;

[0054] In the second state: the driving assembly 32 drives the photographing assembly 22 to rotate in the reverse direction. At this time, a part of the outer edge of the photographing assembly 22 will be blocked by the positioning assembly 23, so that only the inner part of the photographing assembly 22 rotates and rubs the inner cavity of the outer edge part for wiping.

[0055] In this embodiment, before endoscopy, hot water is introduced into the long tube assembly 21 for preheating to reduce patient discomfort and improve the examination efficiency. After the long tube assembly 21 and the flexible tube 12 enter the patient's body, the imaging assembly 22 starts to work. By means of the imaging component arranged therein, high-definition images of the inner wall of the digestive tract can be captured to ensure a full-range observation of the digestive tract from different angles. During the examination, if the imaging component is blocked by body fluids or residues, the wiping of the camera can be achieved through the coordinated operation of the power supply component 31 and the driving component 32 in the regulation component 30. By pulling the driving component 32 to operate, the power supply component 31 is driven to rotate in the reverse direction, and then the imaging assembly 22 is driven to rotate in the reverse direction. At this time, the limiting part of the positioning component 23 will fix the outer shell of the imaging assembly 22, and only allow the inner ring part of the imaging assembly 22 to rotate. In this way, the imaging part of the imaging assembly 22 will continuously rub the inner wall of its outer shell part for wiping, so as to remove the blocking object and restore a clear imaging field of view. When the imaging assembly 22 is driven to rotate forward, its inner ring part and outer shell part will rotate together, so that the imaging part can capture different orientations of the digestive tract, improving the rigor of the examination. After the examination is completed, the outer shell of the imaging assembly 22 can be disassembled for thorough cleaning and disinfection to ensure the hygiene of the probe assembly 20 and prepare for the next examination.

[0056] Secondly, please refer to again Figures 1 to 3 、 Figures 9 to 10 The holding assembly 11 includes a handle 111. A plurality of rotary handles 112 are hinged to the top of the handle 111. An inlet 113 and a drain 114 are respectively formed on the right side of the handle 111.

[0057] The long tube assembly 21 includes a tube body 211 fixedly connected to the bottom end of the flexible tube 12. A heat conducting tube 212 is fixedly connected to the inner cavity of the tube body 211. The top end of the heat conducting tube 212 communicates with a water inlet pipe 213, and the bottom end of the heat conducting tube 212 communicates with a drain pipe 214. The water inlet pipe 213 and the drain pipe 214 penetrate through the flexible tube 12 and communicate with the inlet 113 and the drain 114 respectively.

[0058] It should be noted that the heat conducting tube 212 is a flexible tube, and the first half of the tube body 211 is a hard material structure. And a component for driving its bending is arranged in the inner cavity of the tube body 211, and the specific position is set above the power supply component 31 in the inner cavity of the tube body 211. And the component for driving the bending is driven to operate through the rotary handle 112 (not shown in the figure, which is a common technical structure in the prior art and will not be described in detail here).

[0059] In this embodiment, before the inspection, warm water is added into the water inlet 113 through an external water pump. At this time, the warm water enters the heat conduction tube 212 through the water inlet pipe 213 and circulates inside, and then is discharged through the drain pipe 214 and the drain port 114, so that the warm water continuously circulates in the heat conduction tube 212 until the outer surface of the tube body 211 reaches a temperature close to that of the human body, thereby preheating the endoscope probe before use and avoiding discomfort to the patient caused by the too low temperature of the probe.

[0060] Secondly, please refer to Figures 3 to 8 again. The photographing assembly 22 includes a top head 221 rotatably connected to the bottom end of the tube body 211. A first camera 222 is fixedly installed on the bottom surface of the top head 221. A second camera 223 is fixedly installed on the outer edge of the top head 221. A sleeve 224 is rotatably connected between the outer edge of the top head 221 and the tube body 211. A wiping plate 225 is fixedly connected to the inner cavity of the sleeve 224. A plurality of magnetic attraction plates 226 are fixedly connected to the inner ring of the bottom surface of the tube body 211.

[0061] The positioning assembly 23 includes a first positioning groove 231 opened on the outer edge of the top head 221. A first positioning block 232 is hinged to the middle of the inner ring of the sleeve 224. The outer ring of the bottom of the first positioning block 232 is movably sleeved in the inner cavity of the first positioning groove 231. A second positioning block 233 is hinged to the outer ring of the bottom end of the tube body 211. Pressure spring pieces 234 are fixedly connected to the bottom surfaces of the first positioning block 232 and the second positioning block 233. The two pressure spring pieces 234 are respectively fixedly connected to the bottom of the inner cavity of the sleeve 224 and the bottom of the inner cavity of the tube body 211. A second positioning groove 235 is opened at the top of the inner ring of the sleeve 224. The outer ring of the top of the second positioning block 233 is movably sleeved in the inner cavity of the second positioning groove 235.

[0062] A plurality of sets of the second positioning block 233 and the second positioning groove 235 are provided and evenly distributed on the inner ring of the sleeve 224 and the outer edge of the tube body 211.

[0063] Magnetic attraction plates 226 are also provided on the inner ring of the top of the top head 221, and the magnetic attraction plates 226 on the top head 221 are adapted to the magnetic attraction plates 226 at the bottom of the tube body 211.

[0064] It should be noted that a plurality of sets of channels and lighting devices are provided at the bottom of the top head 221, including a channel for flushing liquid and a channel for inserting a micro operating device (this is a common structure in the prior art and will not be described in detail here).

[0065] The orientations of the first positioning block 232 and the second positioning block 233 are opposite. When the top head 221 rotates forward, the first positioning block 232 drives the sleeve 224 to rotate. At this time, the second positioning block 233 will be pushed into the tube body 211 to avoid affecting its rotation. When rotating in the reverse direction, the first positioning block 232 will be pushed inside the sleeve 224, and the second positioning block 233 will block the sleeve 224 from moving, resulting in a relative rotational movement state between the sleeve 224 and the top head 221, facilitating the top head 221 to contact the wiping plate 225.

[0066] In addition, since the position of the second positioning block 233 is fixed, when wiping, the sleeve 224 needs to be reset first to avoid the rotation of the sleeve 224 during wiping, which affects the wiping effect.

[0067] A soft airbag ring is provided on the outer circumference of the bottom end of the sleeve 224 to reduce the foreign body sensation when contacting the patient's digestive tract. When disassembling the sleeve 224, the first positioning block 232 needs to be retracted by rotating the sleeve 224 forward first, and then the second positioning block 233 needs to be retracted by rotating the sleeve 224 in the reverse direction. The sleeve 224 cannot be removed by only rotating forward or in the reverse direction, which is convenient for subsequent cleaning and also avoids accidents caused by the sleeve 224 being left in the patient's body.

[0068] In this embodiment, after the tube body 211 and the flexible tube 12 enter the patient's body, the first camera 222 and the second camera 223 start to capture images. Since the bottom of the top head 221 is designed with a lighting device, sufficient light can be provided even in the dark of the digestive tract to ensure the clarity of the images. The first camera 222 and the second camera 223 shoot from different angles, enabling the doctor to obtain a comprehensive view of the inner wall of the digestive tract. When more detailed observation of a specific area is required, the driving assembly 32 can be used to drive the energy supply assembly 31 and the top head 221 to rotate forward. At this time, the top head 221 and the sleeve 224 will rotate together, causing the second camera 223 to rotate and adjust its orientation to capture the inner wall of the digestive tract in different orientations. When rotating forward, the second positioning block 233 will be pressed into the inner cavity of the tube body 211 by the sleeve 224 rotating forward to avoid affecting its rotation, while the first positioning block 232 will protrude, enabling the top head 221 to drive the sleeve 224 to rotate together. During the inspection process, if the second camera 223 is blocked, the reverse rotation function of the energy supply assembly 31 and the driving assembly 32 can be used. At this time, the first positioning block 232 will be pushed inside the sleeve 224 by the top head 221 rotating in the reverse direction, and the second positioning block 233 will be pushed by the compression spring piece 234 to rotate outward, blocking the sleeve 224 from moving, resulting in a relative rotational movement state between the sleeve 224 and the top head 221, causing the second camera 223 to contact the wiping plate 225 and wipe off the body fluid attached to its surface, restoring a clear view.

[0069] Secondly, please refer to again Figures 11 to 15, the energy supply component 31 includes a rotating shaft rod 311 fixedly connected to the top end of the top head 221. The bottom of the inner cavity of the pipe body 211 is electrically connected to a power supply head 312. The outer ring of the power supply head 312 is electrically connected to the inner cavity at the top end of the rotating shaft rod 311. A gear ring 313 is fixedly connected to the outer ring at the top end of the rotating shaft rod 311;

[0070] The driving component 32 includes a gear 321 rotatably connected to the middle of the inner cavity of the pipe body 211. The outer ring of the gear 321 meshes with the outer ring of the gear ring 313. An arc-shaped groove 322 is provided in the inner ring of the gear 321. Square blocks 323 are slidably connected to both the upper and lower sides of the inner cavity of the pipe body 211. A sliding rod 324 is fixedly connected between the square blocks 323. The sliding rod 324 is slidably connected to the inner ring of the gear 321. A spiral strip 325 is fixedly connected to the outer ring of the sliding rod 324. The outer ring of the spiral strip 325 is slidably connected to the outer ring of the arc-shaped groove 322. A spring 326 is fixedly connected to the top of the square block 323 at the top. The top end of the spring 326 is fixedly connected to the top of the inner cavity of the pipe body 211. Pulling ropes 327 are fixedly connected to the mutually remote sides of the upper and lower groups of square blocks 323. The pulling ropes 327 pass through the pipe body 211 and the flexible hose 12 and are fixedly connected to the bottom of the rotary handle 112;

[0071] The power supply head 312 is a contact power supply device, and a device for receiving power adapted to it is provided in the inner cavity of the rotating shaft rod 311.

[0072] It should be noted that a raised circular ring is provided in the middle of the inner cavity of the pipe body 211, and the inner ring of the gear 321 is rotatably connected to the outer edge of the circular ring through a bearing, aiming to prevent the gear 321 from falling off and improve the smoothness of rotation;

[0073] The pulling rope 327 is an annular rope, and its two ends are respectively fixed to the middle of the upper and lower square blocks 323, aiming to control the forward and reverse operation of the pulling rope 327 by rotating the rotary handle 112 forward and backward, which is convenient for operation.

[0074] In this embodiment, during daily operation, the power supply head 312 supplies energy to the top head 221 through the rotating shaft rod 311, which is convenient for the normal use of the device. When it is necessary to drive the top head 221 to rotate, the rotary handle 112 is rotated to drive the pulling rope 327 to move. At this time, the pulling rope 327 drives the square blocks 323 and the sliding rod 324 to slide in the inner cavity of the pipe body 211, so that the spiral strip 325 passes through the arc-shaped groove 322, and the gear 321 is driven to rotate by the curvature of its surface. Then, the gear ring 313 and the rotating shaft rod 311 are driven to rotate by the gear 321, so that the top head 221 rotates, realizing the convenient driving of the top head 221 and facilitating the wiping and orientation adjustment work operation.

[0075] The working principle of the present invention is as follows: Before the examination, warm water is added into the water inlet 113, and the warm water enters the heat conduction tube 212 through the water inlet pipe 213 and circulates continuously until the outer surface of the tube body 211 reaches a temperature close to that of the human body, so as to avoid discomfort caused to the patient due to the too low temperature of the probe. After the tube body 211 and the hose 12 enter the patient's body, the first camera 222 and the second camera 223 start to capture images and shoot from different angles respectively, so that the doctor can obtain a comprehensive view of the inner wall of the digestive tract. At this time, the power supply head 312 supplies energy to the top head 221 through the rotating shaft rod 311 to facilitate the normal use of the device. When it is necessary to drive the top head 221 to rotate, the driving handle 112 is rotated to drive the pull rope 327 to move. At this time, the pull rope 327 drives the square block 323 and the sliding rod 324 to slide in the inner cavity of the tube body 211, so that the spiral strip 325 passes through the arc groove 322, and the gear 321 is driven to rotate by the radian of its surface, and the driving gear ring 313 and the rotating shaft rod 311 rotate, so that the top head 221 rotates. If the top head 221 rotates forward, the second positioning block 233 will be pressed into the inner cavity of the tube body 211 by the forwardly rotating sleeve 224 to avoid affecting its rotation, while the first positioning block 232 will protrude, so that the top head 221 can drive the sleeve 224 to rotate together. When the second camera 223 is blocked, the top head 221 can be driven to rotate in the reverse direction. At this time, the first positioning block 232 will be pushed into the inside of the sleeve 224 by the reversely rotating top head 221, while the second positioning block 233 will be pushed by the compression spring piece 234 to rotate outwards to block the sleeve 224 from moving, resulting in a relative rotational movement state between the sleeve 224 and the top head 221, so that the second camera 223 contacts the wiping plate 225 and wipes off the body fluid attached to its surface, restoring a clear vision.
