Description

Technical Field

[0001] This utility model relates to the field of anorectal examination endoscope technology, and in particular to an easily adjustable anorectal examination endoscope. Background Technology

[0002] The incidence of anorectal diseases is on the rise globally, and accurate diagnosis is crucial for developing effective treatment plans and promoting patient recovery. As an important instrument for doctors to diagnose anorectal diseases, the performance of the anorectal endoscope directly affects the accuracy and efficiency of diagnosis.

[0003] Due to the complex physiological structure of the anorectal region, including numerous bends and folds, existing examination endoscopes cannot flexibly and comprehensively cover these areas, leading to blind spots in observation. Some minute lesions or early-stage lesions may go undetected because they are in these blind spots, delaying early diagnosis and potentially causing patients to miss the optimal treatment window, seriously impacting their health. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an easily adjustable anorectal examination endoscope, thereby solving the technical problem that existing anorectal examination endoscopes have significant limitations in the adjustment of the observation angle.

[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: An easily adjustable anorectal examination endoscope, comprising: a cylindrical body; a sphere rotatably mounted at one end of the cylindrical body; a camera mounted at the end of the sphere away from the cylindrical body; an axial adjustment block rotatably mounted at the other end of the cylindrical body, the axial adjustment block being used to control the rotation of the sphere along the axial centerline of the cylindrical body; two connecting ropes, one end of which is connected to the sphere, the connecting ropes being used to control the illumination direction of the camera on the sphere to gradually rotate towards the outer periphery of the cylindrical body, wherein the surface of the cylindrical body is finely ground and polished to reduce friction on the intestine. The sphere is made of ceramic material with an extremely smooth surface, which can flexibly change the angle during rotation without causing damage to the intestinal wall; the camera is a high-definition medical miniature camera with an automatic dimming function, which can adjust the brightness according to different lighting conditions in the anorectal cavity to ensure clear imaging; the axial adjustment block is connected to the cylindrical body through a high-precision ball bearing, making the rotation both smooth and precise; the connecting ropes are made of high-strength, corrosion-resistant medical-grade aramid fiber rope, which has good flexibility and can adapt to complex extension and retraction movements.

[0006] In a further embodiment, a connecting rod is connected at one end to an axial adjusting block; a connecting block is connected at one end to the other end of the connecting rod, and the other end is slidably connected to a ball; the connecting rod and the connecting block are used to transmit the rotational force of the axial adjusting block to the ball, wherein the connecting rod is made of lightweight and high-strength titanium alloy, which reduces the overall weight while ensuring structural strength; the sliding connection between the connecting block and the ball adopts a dovetail groove and slider form, the dovetail groove design can effectively prevent the connecting block from shifting during sliding, ensuring the stability of the connection; the connecting rod and the axial adjusting block are connected by a tightly fitting spline, which can efficiently transmit torque, so that the rotational force of the axial adjusting block can be accurately transmitted to the ball.

[0007] In a further embodiment, a retractor is rotatably mounted within an axial adjustment block. One end of the retractor passes through the axial adjustment block, and the other end of the retractor is connected to two connecting ropes. The retractor is used to retract the connecting ropes. The retractor is made of high-strength polycarbonate material, which has good wear resistance and corrosion resistance. The surface of the retractor is machined with threaded grooves to ensure a tight fit with the connecting ropes and prevent slippage. The retractor is mounted within the axial adjustment block via two deep groove ball bearings, making its rotation more flexible and smooth. The portion of the retractor extending beyond the axial adjustment block is provided with anti-slip textures for easy connection to external operating components.

[0008] In a further embodiment, an adjustment knob is connected to one end of the retractor. The adjustment knob is used to control the rotation of the retractor. The adjustment knob adopts an ergonomic design and is covered with anti-slip rubber for easy operation by the doctor. The adjustment knob and the retractor are connected by a flat key to ensure that the two rotate synchronously and achieve precise control. The adjustment knob is equipped with a scale, and the scale on the scale is calibrated according to the rotation angle of the retractor and the length of the connecting rope, so that the doctor can intuitively understand the adjustment status.

[0009] In a further embodiment, there are two storage slots, each used to store two connecting ropes. The inner surface of each storage slot is smooth and has a soft rubber pad to prevent the connecting ropes from being scratched during storage and release. The storage slots are designed in a spiral shape to match the winding shape of the connecting ropes, which can effectively reduce the tangling of the connecting ropes. The two storage slots are symmetrically distributed within the axial adjustment block to ensure structural balance.

[0010] In another embodiment, the winding rod passes through two storage slots, with the winding rod passing through the center of both slots. Positioning sleeves are provided at both ends of the storage slots. These positioning sleeves are made of copper alloy, which has good wear resistance and self-lubricating properties, reducing friction between the winding rod and the storage slots and ensuring smooth rotation of the winding rod. The positioning sleeves are interference-fitted with the storage slots to ensure a secure installation.

[0011] In a further embodiment, the connection points of the two connecting ropes on the sphere are symmetrical along the axial centerline of the connecting rod. The connection points of the two connecting ropes on the sphere are fixed by special metal connectors. The connectors are bonded to the sphere with high-strength adhesive and mechanically reinforced to ensure a firm and reliable connection. The connection points are symmetrically distributed along the axial centerline of the connecting rod, so that the sphere can maintain uniform force when subjected to the tension of the connecting ropes, thus achieving stable rotation.

[0012] In a further embodiment, the two connecting ropes are wound clockwise and counterclockwise in the winding direction of the winding rod, respectively.

[0013] In another embodiment, the connecting rod is provided with multiple limiting blocks for positioning the connecting rope. These limiting blocks are made of rubber, which provides good elasticity and wear resistance. The limiting blocks are U-shaped to tightly wrap around the connecting rope, preventing it from shifting or tangling during movement. The limiting blocks are fixed to the connecting rod via slots, making installation and disassembly convenient, and facilitating maintenance and replacement.

[0014] Compared with existing technologies, this application has the following technical advantages:

[0015] The axial adjustment block, connecting rod, connecting block, sphere, connecting rope, winding rod, and adjustment knob work together to achieve flexible and omnidirectional adjustment of the examination endoscope's observation angle. The axial adjustment block is rotatably mounted at the other end of the cylinder, and the rotational force is transmitted to the sphere, which is rotatably mounted at one end of the cylinder, through the connecting rod and connecting block. The adjustment knob connects to the winding rod, controlling its rotation. The winding rod then winds up the two connecting ropes connected to the sphere, and the connection positions of the two connecting ropes on the sphere are symmetrical along the axial center line of the connecting rod, with the winding directions being clockwise and counterclockwise, respectively. In actual use, doctors can easily adjust the angle of the examination endoscope to comprehensively observe the inside of the anorectal cavity, effectively reducing blind spots and improving the accuracy of the examination.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Example:

[0024] like Figures 1 to 4 This application discloses an easily adjustable anorectal examination endoscope, comprising: a cylindrical body 1; a sphere 2 rotatably disposed at one end of the cylindrical body 1; a camera 3 mounted at the end of the sphere 2 away from the cylindrical body 1; an axial adjustment block 4 rotatably disposed at the other end of the cylindrical body 1, the axial adjustment block 4 being used to control the rotation of the sphere 2 along the axial centerline of the cylindrical body 1; and two connecting ropes 6, one end of which is connected to the sphere 2, the connecting ropes 6 being used to control the illumination direction of the camera 3 on the sphere 2 to gradually rotate towards the periphery of the cylindrical body 1.

[0025] By adopting the above technical solution, the layout of the basic structure of the detection endoscope and the preliminary angle adjustment function are realized; the cylinder 1 serves as the main supporting component, the sphere 2 can rotate so that the camera 3 can change its orientation, the axial adjustment block 4 controls the sphere 2 to rotate along the axial center line of the cylinder 1, and the two connecting ropes 6 control the sphere 2 to rotate towards the outer periphery of the cylinder 1, which provides a basis for multi-angle observation of the inside of the anorectal cavity and expands the observation range.

[0026] See Figure 4 This application also includes a connecting rod 402, one end of which is connected to the axial adjustment block 4; and a connecting block 4021, one end of which is connected to the other end of the connecting rod 402, and the other end of which is slidably connected to the ball 2. The connecting rod 402 and the connecting block 4021 are used to transmit the rotational force of the axial adjustment block 4 to the ball 2. By setting the connecting rod 402, the rotational force of the axial adjustment block 4 is effectively transmitted; the connecting rod 402 and the connecting block 4021 transmit the rotational force of the axial adjustment block 4 to the ball 2, so that the doctor can accurately control the rotation of the ball 2 by operating the axial adjustment block 4, ensuring the continuity and stability of the adjustment, and allowing the camera 3 to change the observation angle according to the doctor's intention.

[0027] See Figure 3This application also includes a winding rod 501, rotatably mounted within the axial adjustment block 4. One end of the winding rod 501 passes through the axial adjustment block 4, and the other end of the winding rod 501 is connected to the two connecting ropes 6. The winding rod 501 is used to wind up the connecting ropes 6. By setting up the winding rod 501, the winding function of the connecting ropes 6 is realized; the winding rod 501 is rotatably mounted within the axial adjustment block 4 and connected to the connecting ropes 6. By winding up the connecting ropes 6, the length of the connecting ropes 6 can be changed, thereby driving the ball 2 to rotate, and further precisely controlling the observation angle of the camera 3.

[0028] See Figure 3 This application also includes an adjustment knob 5, connected to one end of the take-up rod 501, which is used to control the rotation of the take-up rod 501. By setting the adjustment knob 5, convenient control of the rotation of the take-up rod 501 is achieved; the adjustment knob 5 is connected to one end of the take-up rod 501, and the doctor can easily control the rotation of the take-up rod 501 by turning the adjustment knob 5, which is simple and direct to operate and improves the efficiency and accuracy of adjustment.

[0029] See Figure 3 This application also includes two storage slots 401, each used to store one of the two connecting ropes 6. By providing the storage slots 401, the connecting ropes 6 are stored in an orderly manner. The two storage slots 401 respectively store the two connecting ropes 6, preventing them from becoming tangled or confused during adjustment, ensuring smooth winding and unwinding, and making the adjustment function of the camera 3 more stable and reliable.

[0030] See Figure 3 The retractor 501 of this application passes through the two storage slots 401 to achieve effective management of the winding of the connecting rope 6. The retractor 501 passes through the two storage slots 401 so that the retractor 501 can simultaneously wind up or release the two connecting ropes 6 when rotating, ensuring the coordinated work of the two connecting ropes 6 and providing a guarantee for the precise rotation of the sphere 2.

[0031] See Figure 4 In this application, the connection positions of the two connecting ropes 6 on the sphere 2 are symmetrical along the axial center line of the connecting rod 402. By adopting the above technical solution, the symmetry and stability of the rotation of the sphere 2 are achieved; the connection positions of the two connecting ropes 6 on the sphere 2 are symmetrical along the axial center line of the connecting rod 402, so that when the connecting ropes 6 are wound or released, the sphere 2 can be evenly stressed, avoiding tilting or shaking, and ensuring the stability and accuracy of the viewing angle adjustment of the camera 3.

[0032] See Figure 3In this application, the two connecting ropes 6 are wound clockwise and counterclockwise in the winding direction of the winding rod 501, respectively. By adopting the above technical solution, the sphere 2 can rotate flexibly in both directions. The two connecting ropes 6 are wound clockwise and counterclockwise in the winding direction of the winding rod 501. By controlling the rotation direction of the winding rod 501, the two connecting ropes 6 can be tightened or loosened respectively, thereby realizing the rotation of the sphere 2 in different directions and further expanding the observation angle range of the camera 3. It also includes a locking component (not shown), which is slidably mounted on the adjusting knob 5. The cylinder 1 is provided with a locking groove, and the locking component is provided with multiple protrusions along its circumference. The locking component locks the winding rod 501 by sliding along the axial direction of the adjusting knob 5 so that the protrusions on it engage with the locking groove. The locking component cannot rotate relative to the adjusting knob 5, so that when the locking component is fixed, the adjusting knob 5 is also fixed.

[0033] See Figure 3 and Figure 4 The connecting rod 402 of this application is provided with multiple limiting blocks for limiting the position of the connecting rope 6. By adopting the above technical solution, the position of the connecting rope 6 is precisely limited; the multiple limiting blocks on the connecting rod 402 limit the position of the connecting rope 6, preventing the connecting rope 6 from deviating from the normal track during movement, ensuring the stability and accuracy of the connecting rope 6 during winding and release, thereby improving the accuracy of the angle adjustment of the camera 3.

[0034] The working principle of this application is as follows: During use, the doctor first holds the cylinder 1 and carefully inserts one end of the ball 2, which is equipped with the camera 3, into the patient's rectum; then, the doctor turns the adjustment knob 5, which drives the winding rod 501 to rotate within the axial adjustment block 4; the winding rod 501 is connected to two connecting ropes 6 and passes through two storage slots 401 for storing the connecting ropes 6 respectively. When the winding rod 501 rotates, the two connecting ropes 6 are wound up and down in clockwise and counterclockwise directions respectively; since one end of the connecting rope 6 is symmetrically connected to the ball 2, as the connecting rope 6 is wound up and down, the ball 2 begins to move outward from the cylinder 1. The camera 3 rotates flexibly, allowing the doctor to observe the inside of the rectum from different angles. If further adjustment of the observation angle is needed, the doctor rotates the axial adjustment block 4, and its rotational force is transmitted to the connecting block 4021 through the connecting rod 402 connected to it. The connecting block 4021 is slidably connected to the ball 2, thereby causing the ball 2 to rotate along the axial center line of the cylinder 1, so that the camera 3 can observe different axial positions inside the rectum. During the entire operation, the limiting block on the connecting rod 402 limits the position of the connecting rope 6, ensuring that the connecting rope 6 works normally and helping the doctor to comprehensively and clearly examine the condition of the rectum.
