Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a portable endoscope. Background Technology

[0002] With the improvement of living standards and life expectancy, colorectal cancer has become one of the most common malignant tumors, making colorectal cancer screening very important.

[0003] Currently, colonoscopy is commonly used for colorectal cancer screening. However, due to its high cost, invasiveness, complex bowel preparation, and high risk of complications, many patients are reluctant to undergo colonoscopy. Furthermore, the simplest method, digital rectal examination, is limited by the length of the doctor's fingers, leading to missed diagnoses, and its over-reliance on the doctor's tactile judgment results in misdiagnosis. Traditional rigid rectoscopes, with their straight, non-bendable shape, easily miss lesions around the anus. Their large diameter and discomfort, along with the risk of anal enlargement affecting sphincter function, make them unsuitable for early rectal cancer screening. Given the needs of a large population, current medical devices for colorectal cancer screening are highly invasive, complex to use, and have low applicability, making them unsuitable for use in areas with limited medical resources.

[0079] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0080] The present invention is described herein with respect to structural embodiments and methods. It should be understood that this is not intended to limit the invention to the specific disclosed embodiments; the invention can be practiced using other features, elements, methods, and embodiments. Similar elements in different embodiments are typically designated with similar numbers.

[0082] like Figure 1 As shown in the figure, an embodiment of the present invention proposes a portable endoscope, including a handheld mechanism 1, a probe mechanism 2 and a drive mechanism 4.

[0083] like Figure 2 and Figure 3 As shown, the detection mechanism 2 is mounted on the handheld mechanism 1 and includes an insertion tube 21 and a camera 22. The interior of the insertion tube 21 is a cavity and is configured to bend and extend into the cavity; the camera 22 is mounted at the end of the insertion tube 21 away from the handheld mechanism 1 and is suitable for acquiring image information.

[0084] like Figure 4 and Figure 5As shown, the drive mechanism 4 includes two pairs of drive wires 41, a positioning plate 42, elastic tubes 43, and a drive assembly 44. The ends of the two pairs of drive wires 41 are respectively connected to the four equal parts of the end of the insertion tube 21; the positioning plate 42 is mounted on the handheld mechanism 1, and the two pairs of drive wires 41 pass through the positioning plate 42 and are spaced apart; multiple elastic tubes 43 are respectively sleeved on the outside of each drive wire 41 and installed between the positioning plate 42 and the end of the insertion tube 21 to tension the insertion tube 21; the drive assembly 44 is mounted on the handheld mechanism 1 and located on the side of the positioning plate 42 away from the insertion tube 21, and is configured to increase or decrease the length of the two pairs of drive wires 41 located between the positioning plate 42 and the end of the insertion tube 21, and the length changes of the two opposing drive wires 41 in the radial direction are opposite, causing the end of the insertion tube 21 to bend.

[0085] According to the portable endoscope disclosed herein, during use, the operator holds the holding mechanism 1 and operates the drive assembly 44, causing the portions of two radially opposite drive wires 41 located between the positioning plate 42 and the end of the insertion tube 21 to lengthen or shorten. The lengthening amount of one drive wire 41 is equal to the shortening amount of the other drive wire 41. The elastic tube 43 tensions the insertion tube 21, thereby causing the end of the insertion tube 21 to bend, thus changing the area where the camera 22 acquires image information. It is minimally invasive, portable, easy to operate, and the position of the camera 22 can be easily changed. It has high applicability and is suitable for remote and rural areas lacking medical resources, which is beneficial to meeting the needs of a large population and popularizing colorectal cancer screening.

[0086] In one exemplary embodiment, such as Figure 1 and Figure 5 As shown, the handheld mechanism 1 includes a first housing and a second housing, which are fastened together by bolts or clips to form a housing structure with an internal cavity.

[0087] In one exemplary embodiment, such as Figure 2 and Figure 3 As shown, the detection mechanism 2 includes an insertion tube 21 and a camera 22. The interior of the insertion tube 21 is hollow and is configured to bend and extend into an internal lumen, such as the rectum.

[0088] Specifically, such as Figure 4As shown, the diameter of the insertion tube 21 is 4mm-8mm, for example, 4mm, 6mm, 8mm, and the length is 100mm-180mm, for example, 100mm, 120mm, 140mm, 160mm, 180mm. The insertion tube 21 includes a connecting tube 211, a bending portion 212, and a protective tube 213. The connecting tube 211 is installed on the handheld mechanism 1 and communicates with the cavity of the handheld mechanism 1; the bending portion 212 is connected to the end of the connecting tube 211 away from the handheld mechanism 1, so as to bend under the drive of the driving mechanism 4; the protective tube 213 is installed at the end of the bending portion 212 away from the connecting tube 211, and the camera 22 is installed at the end of the protective tube 213, which is suitable for acquiring image information.

[0089] In one exemplary embodiment, the bending portion 212 includes a snake-bone tube 2121, a metal mesh 2122, and a rubber tube 2123. The snake-bone tube 2121 is connected between the connecting tube 211 and the protective tube 213 to allow the bending portion 212 to bend; the metal mesh 2122 is sleeved over the snake-bone tube 2121 to enhance its toughness and load-bearing capacity; the rubber tube 2123 is sleeved over the metal mesh 2122 and covers the connection points of the snake-bone tube 2121 with the connecting tube 211 and the protective tube 213 respectively, to strengthen the protection of the metal mesh 2122. The rubber tube 2123 is elastic and smooth, which enhances the sealing of the connection points of the snake-bone tube 2121 with the connecting tube 211 and the protective tube 213, while improving the comfort of use and reducing the sense of intrusion.

[0090] In one exemplary embodiment, such as Figure 5 As shown, the drive mechanism 4 includes two pairs of drive wires 41, a positioning plate 42, an elastic tube 43, and a drive assembly 44. The ends of the two pairs of drive wires 41 are respectively connected to the quarter positions of the ends of the snake tube 2121; the positioning plate 42 is installed on the handheld mechanism 1, and the two pairs of drive wires 41 can slide through the positioning plate 42 and are spaced apart; the elastic tube 43 is sleeved on the drive wires 41. In this embodiment, the elastic tube 43 is a spring tube, installed between the positioning plate 42 and the end of the insertion tube 21. The elastic tube 43 is in a compressed state and pushes the insertion tube 21 away from the positioning plate 42 by elastic force to tension the insertion tube 21; the drive assembly 44 is installed on the handheld mechanism 1 and is located on the side of the positioning plate 42 away from the insertion tube 21. It is configured to increase or decrease the length of the two pairs of drive wires 41 located between the ends of the positioning plate 42 and the insertion tube 21, and the length changes of the two opposing drive wires 41 in the radial direction are opposite, causing the end of the insertion tube 21 to bend.

[0091] Figure 6 This is a partial cross-sectional perspective view of the drive assembly of a portable endoscope according to an embodiment of the present invention. Figure 7 This is a cross-sectional schematic diagram of the winding wheel of a portable endoscope according to an embodiment of the present invention.

[0092] In one exemplary embodiment, such as Figure 5 and Figure 6 As shown, the drive assembly 44 includes a first operating assembly and a second operating assembly. Both the first and second operating assemblies are rotatably mounted on the handheld mechanism 1. Two pairs of drive wires 41 are respectively mounted on the first and second operating assemblies, so that under the rotational drive of the first and / or second operating assemblies, the two drive wires 41 arranged opposite each other in the radial direction elongate or shorten proportionally, causing the end of the insertion tube 21 to bend.

[0093] Specifically, such as Figure 5 and Figure 6 As shown, the first operating component includes a long shaft section 441, a first operating wheel 442, and two first winding wheels 443. The first end of the long shaft section 441 passes through the hand-held mechanism 1 and extends into the inner cavity of the hand-held mechanism 1. The first end of the long shaft section 441 located inside the hand-held mechanism 1 is rotatably mounted on the hand-held mechanism 1. The first operating wheel 442 is located outside the hand-held mechanism 1 and is mounted on the second end of the long shaft section 441 to drive the long shaft section 441 to rotate. The two first winding wheels 443 are sleeved on the long shaft section 441 near the first end, and the circumferential surfaces of the two first winding wheels 443 are provided with first threaded grooves 4431 with opposite helical directions. The first threaded grooves 4431 are suitable for mounting a pair of oppositely arranged drive wires 41.

[0094] like Figure 5 and Figure 6 As shown, the second operating component includes a second operating wheel 445, a bushing section 444, and two second winding wheels 446. The second operating wheel 445 is located outside the handheld mechanism 1 and is rotatably mounted inside the first operating wheel 442; the bushing section 444 is rotatably sleeved outside the long shaft section 441 and is installed between the second operating wheel 445 and the first winding wheel 443, so that the bushing section 444 can be driven to rotate relative to the long shaft section 441 by operating the second operating wheel 445; the two second winding wheels 446 are sleeved on the bushing section 444, and the circumferential surfaces of the two second winding wheels 446 are provided with second threaded grooves 4461 with opposite helical directions, the second threaded grooves 4461 being suitable for installing another pair of oppositely arranged drive wires 41.

[0095] In one exemplary embodiment, such as Figure 7 As shown, tensioning holes 448 are provided on the side walls of the first winding wheel 443 and the second winding wheel 446. The tensioning holes 448 are suitable for inserting a wrench to adjust the initial posture of the end of the insertion tube 21 by rotating the first winding wheel 443 and / or the second winding wheel 446. The initial state is when the bent part 212 and the connecting tube 211 are in a straight line.

[0096] In one exemplary embodiment, such as Figure 7As shown, both first winding wheels 443 and two second winding wheels 446 are threadedly connected with set screws 447. The set screws 447 are configured to pass through the first winding wheels 443 and the second winding wheels 446 and abut against the bushing section 444 and the long shaft section 441 respectively, so as to prevent the first winding wheels 443 and the second winding wheels 446 from rotating relative to the bushing section 444 and the long shaft section 441 respectively.

[0097] According to an embodiment of this disclosure, during assembly, the ends of two pairs of drive wires 41 are respectively installed at the quarter points of the snake tube 2121. The two pairs of drive wires 41 slidably pass through the positioning plate 42. One pair of drive wires 41, with one end away from the snake tube 2121, is wound around the first thread groove 4431 of the two first winding wheels 443. The other pair of drive wires 41, with one end away from the snake tube 2121, is wound around the second thread groove 4461 of the two second winding wheels 446. The operator inserts a wrench into the tensioning hole 448 to apply force to the first winding wheels 443 and the second winding wheels 446, so that the first winding wheels 443 and the second winding wheels 446 rotate relative to the long shaft section 441 and the bushing section 444, respectively, to tension the drive wires 41 wound on the first winding wheels 443 and the second winding wheels 446. After the drive wire 41 is tensioned, the set screw 447 is rotated, causing the set screw 447 to abut against the long shaft section 441 and the bushing section 444, thereby fixing the first winding wheel 443 and the second winding wheel 446 relative to the long shaft section 441 and the bushing section 444. The assembly operation is convenient.

[0098] When the operating drive mechanism 4 bends the bending section 212, the first operating wheel 442 is rotated, thereby driving the long shaft section 441 and the first winding wheel 443 to rotate. Since the first thread grooves 4431 of the two first winding wheels 443 have opposite spiral directions, the portions of the two driving wires 41 opposite each other in the radial direction of the snake tube 2121 located between the positioning plate 42 and the end of the insertion tube 21 are lengthened or shortened respectively, and the amount of change is the same, thereby causing the snake tube 2121 to bend in the plane formed by a pair of driving wires 41. The second operating wheel 445 is rotated, thereby driving the bushing section 444 and the second winding wheel 446 to rotate, thereby causing the snake tube 2121 to bend in the plane formed by another pair of driving wires 41, thereby adjusting the range of image information acquired by the camera 22. It is portable, easy to operate, and easy to change the position of the camera 22. It has high applicability and is suitable for remote and rural areas with scarce medical resources, which is beneficial to meeting the needs of a large population and popularizing colorectal cancer screening.

[0099] Figure 8 This is a schematic diagram of the installation of the display mechanism of a portable endoscope according to an embodiment of the present invention.

[0100] In one exemplary embodiment, such as Figure 8As shown, the handheld mechanism 1 is also provided with a display mechanism 3, including a display 31 and a clamping mechanism. The display 31 is placed on the placement platform of the handheld mechanism 1. In this embodiment, the display 31 is a mobile phone, but the display 31 can also be a tablet or the like. The display 31 receives image information acquired from the camera 22 and displays the image information. The clamping mechanism is movably mounted on the handheld mechanism 1 and is suitable for mounting the display 31 on the handheld mechanism 1.

[0101] Specifically, such as Figure 8 As shown, the handheld mechanism 1 is provided with a guide block 11, and the clamping mechanism includes a clamping part 32 and an elastic element 33. In this embodiment, the elastic element 33 is a spring, and the block slides within the slide groove 321. The clamping part 32 is slidably mounted on the handheld mechanism 1. The elastic element 33 is installed between the bottom of the slide groove 321 of the clamping part 32 and the guide block 11 of the handheld mechanism 1. The clamping part 32 is provided with a slide groove 321 directly opposite the guide block 11, so that the guide is configured to drive the clamping part 32 to move toward the placement table, so as to clamp the display 31 between the clamping part 32 and the placement table.

[0102] According to an embodiment of this disclosure, the operator pulls the clamping part 32 away from the placement platform of the handheld mechanism 1, and the elastic member 33 is continuously compressed. Then, the display 31 is placed on the placement platform of the handheld mechanism 1, the external force on the clamping part 32 is released, the elastic member 33 extends, and the clamping part 32 moves towards the placement platform of the handheld mechanism 1, thereby clamping the display 31.

[0103] Figure 9 This is a cross-sectional schematic diagram of the handheld mechanism of a portable endoscope according to an embodiment of the present invention.

[0104] In one exemplary embodiment, such as Figure 1 and Figure 9 As shown, the display 31 and the camera 22 are connected either wired or wirelessly. In this embodiment, the display 31 and the camera 22 are connected wirelessly. The handheld mechanism 1 is equipped with a wireless signal module 5, which includes a power supply 51, a wireless signal transmitting chip 52, and a start button 53. The power supply 51 is installed in the inner cavity of the handheld mechanism 1 to provide power; the wireless signal transmitting chip 52 is electrically connected to the power supply 51 and is used to receive image information acquired from the camera 22, so that the display 31 can acquire and display the image information; the start button 53 is installed in the handheld mechanism 1 and is electrically connected to the wireless signal transmitting chip 52 to control the wireless signal transmitting chip 52 to turn on or off.

[0105] According to the embodiments of this disclosure, after the operator clamps the display 31 onto the placement table of the clamping part 32 and the handheld mechanism 1, the insertion tube 21 is inserted into the natural cavity of the human body. The position of the camera 22 is adjusted by operating the drive mechanism 4 as needed. The image information acquired by the camera 22 is transmitted to the display 31 and displayed through the wireless signal module 5. The operation is simple, the position of the camera 22 can be easily changed and the image information can be displayed. It is portable and suitable for remote and rural areas with scarce medical resources.

[0106] In one exemplary embodiment, such as Figure 3 and Figure 9 As shown, the portable endoscope also includes an illumination mechanism 6, which includes a control button 61, an auxiliary light 62, and a light intensity adjustment chip 63. The control button 61 is mounted on the handheld mechanism 1; the auxiliary light 62 is mounted on the camera 22, and multiple auxiliary lights 62 are arranged around the camera 22 to make the light uniform; the light intensity adjustment chip 63 is electrically connected to the power supply unit 51, and the light intensity adjustment chip 63 is electrically connected to the control button 61 and the auxiliary light 62 in sequence, and adjusts the light intensity of the auxiliary light 62 under the drive of the control button 61.

[0107] According to the embodiments of this disclosure, when the camera 22 is in the environment of the human body's natural cavity to acquire image information, when the ambient light is dim, the operation control button 61 adjusts the light intensity adjustment chip 63 to adjust the light intensity of the auxiliary lamp 62 and improve the illumination. When there is a lot of body fluid in the human body's natural cavity, a reflection phenomenon will occur, resulting in a large area of ​​white light in the acquired image. At this time, it is necessary to operate the control button 61 to adjust the light intensity adjustment chip 63 to reduce the light intensity of the auxiliary lamp 62, so as to facilitate the adjustment of the light intensity, improve the ambient light, and acquire clear image information.

[0108] Figure 10 This is a three-dimensional schematic diagram of the inflation mechanism of a portable endoscope according to an embodiment of the present invention.

[0109] In one exemplary embodiment, such as Figure 1 and Figure 10 As shown, the portable endoscope also includes an inflation mechanism 7, which includes an air supply tube 71, an air bladder 72, and a one-way valve 73. One end of the air supply tube 71 extends into the cavity inside the insertion tube 21 and communicates with the outside of the insertion tube 21 through the through hole 2131 of the insertion tube 21. The other end extends to the handheld mechanism 1 and passes through the handheld mechanism 1 and is located outside the handheld mechanism 1. The air bladder 72 is connected and disposed at the end of the air supply tube 71 away from the insertion tube 21. The one-way valve 73 is installed between the air supply tube 71 and the air bladder 72.

[0110] According to an embodiment of this disclosure, the operator holds the airbag 72 and continuously squeezes it, so that the inflated gas enters the gas delivery tube 71 through the one-way valve 73 and is delivered along the gas delivery tube 71 to the end of the insertion tube 21. Then the gas enters the human body natural cavity through the through hole 2131 of the insertion tube 21, thereby inflating the human body natural cavity, filling the human body natural cavity, relaxing the mucosa, and reducing missed diagnoses.

[0111] According to the portable endoscope disclosed herein, during use, the operator holds the holding mechanism 1 and operates the drive assembly 44, causing the portions of two radially opposite drive wires 41 located between the positioning plate 42 and the end of the insertion tube 21 to lengthen or shorten. The lengthening amount of one drive wire 41 is equal to the shortening amount of the other drive wire 41. The elastic tube 43 tensions the insertion tube 21, thereby bending the end of the insertion tube 21 and changing the area where the camera 22 acquires image information. The operation is simple. The inflation mechanism 7 inflates the body's natural cavities, making them full. The illumination mechanism 6 adjusts the ambient light of the camera 22 to facilitate the acquisition of clear images. Subsequently, the display 31 receives and displays the image information acquired by the camera 22, completing the screening. The portable endoscope is minimally invasive, portable, easy to operate, and allows for easy repositioning of the camera 22. It has high applicability and is suitable for remote and rural areas lacking medical resources, thus meeting the needs of a broad population and promoting colorectal cancer screening.

[0112] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
