Abstract
Description
Technical Field
[0001] This utility model relates to an endoscope driving structure, and particularly to an endoscope driving structure and an endoscope. Background Technology
[0002] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It comprises an image sensor, optical lens, light source illumination, and mechanical devices, and is widely used in industries such as manufacturing and medicine.
[0003] Currently, in the domestic industrial endoscope field, the driving methods are divided into two categories: electric drive and manual drive with a steering mechanism at the front end of the endoscope. In electric drive, the traction wire (such as tungsten wire, steel wire, etc.) in the endoscope is connected to the rudder, and a connecting pin, usually a welded pin, protrudes at the connection point.
[0004] There are some drawbacks in its use, mainly including: 1. If there is insufficient space around the servo when it is turning, the welding pin may get stuck, or even the entire servo disc and the servo may get stuck at the same time, causing the servo to burn out and the equipment to be damaged. 2. The distance the servo motor pulls the traction wire is related to the diameter of the servo disc. In long-distance pipelines, a larger diameter servo disc is required, making it difficult to reduce the size of the servo disc. 3. Since the servo motor directly drives the steer wheel to rotate, it is impossible to feel whether the front steering mechanism is stuck when turning. If the servo motor continues to rotate, the connecting pin of the traction wire (such as the welding pin) may fall off, causing the head end to be unable to turn. 4. Once the endoscope tubing is welded to the steering wheel adapter, it is difficult to remove it for maintenance, which greatly increases the cost of later maintenance. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide an endoscope driving structure and an endoscope, which solves the problems of easy damage and difficult maintenance of existing driving structures.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0017] Example 1 like Figure 1-5 As shown, this embodiment provides an endoscope driving structure, including a servo motor 4 and a servo disk 5, wherein the servo motor 4 is used to drive the servo disk 5; The rudder disk 5 has mounting slots 501, with two mounting slots 501 formed by openings 502. Rudder disk adapters 9 are respectively installed in the two mounting slots 501, and the two rudder disk adapters 9 are arranged in a cross configuration through the reasonable layout of the openings 502. During the rotation of the rudder disk 5, when one rudder disk adapter 9 pulls the traction wire 12, the other rudder disk adapter 9 can effectively avoid motion interference and avoid jamming.
[0018] Specifically, in this embodiment, both mounting slots 501 are provided with steering wheel adapters 9, wherein the two steering wheel adapters 9 are arranged crosswise. When one of the traction wire fixing seats 6 pulls the traction wire 12, the other traction wire fixing seat 6 can be avoided from blocking its movement, thus avoiding interference. Each steering wheel adapter 9 is equipped with a traction wire fixing seat 6, which is used to connect the traction wire 12.
[0019] Specifically, the traction wire fixing seat 6 is connected to the traction wire 12 via the connecting pin 7, wherein the end of the traction wire 12 is installed inside the clamp tube 8.
[0020] The clamp tube 8 is used to fix the traction wire 12, and is mounted on the traction wire fixing seat 6. The cross-section of the clamp tube 8 includes polygons and circles, preferably hexagons, which can achieve a stable fixation of the traction wire 12. The clamp tube 8 is used to fix the traction wire 12, and is mounted on the traction wire fixing seat 6 to achieve a firm fixation of the traction wire by mechanical clamping. The cross-section of the clamp tube 8 includes polygons and circles, preferably hexagons. This polygonal cross-section design can effectively enhance the clamping force and prevent the traction wire from slipping or loosening under force. With the setting of the clamp tube, even if the connecting pin 7 is accidentally dislodged, the traction wire 12 can still be kept fixed by the clamp tube 8, thereby avoiding equipment damage or steering failure caused by loosening of the traction wire, and significantly improving the reliability and safety of the endoscope drive structure.
[0021] like Figure 4-5 As shown, the cross-section of the mounting groove 501 has an arc-shaped segment 5011, and the radius of curvature of the arc-shaped segment gradually increases along its extension direction, which can effectively increase the traction distance to cope with the pulling operation of large-sized traction wires. The motion trajectory of the steering disk adapter 9 in the groove is optimized. When the steering disk 5 rotates clockwise or counterclockwise, the change in depth of the mounting groove 501 causes the steering disk adapter 9 to generate a corresponding linear displacement, thereby effectively increasing the pulling stroke of the traction wire 12. This involute groove structure is particularly suitable for long-distance pipeline operation, which can ensure sufficient traction stroke and adapt to the pulling requirements of large-sized traction wires through the change in groove depth. It achieves a longer traction distance without increasing the size of the steering disk, improving the adaptability and reliability of endoscope steering control.
[0022] Specifically, when the servo motor 4 receives a control signal and starts working, its output shaft drives the servo disk 5 to rotate. The servo disk 5 is provided with two mounting slots 501 formed through the opening 502, and servo disk adapters 9 are respectively installed in these two mounting slots 501, which are arranged in a cross manner. During the rotation of the rudder disk 5, the special structural design of the mounting groove 501 plays a crucial role. The cross-section of the mounting groove 501 has an arc-shaped segment, and the radius of curvature of this arc-shaped segment gradually increases along its extension direction. This involute groove structure optimizes the movement trajectory of the rudder disk adapter 9 within the groove. When the rudder disk 5 rotates clockwise or counterclockwise, the change in depth of the mounting groove 501 causes the rudder disk adapter 9 to generate a corresponding linear displacement, thereby effectively increasing the pulling stroke of the traction wire 12. The traction wire fixing seat 6 installed on the rudder disk adapter 9 is connected to the traction wire 12 via a connecting pin 7. The end of the traction wire 12 is installed inside a clamp tube 8, which is fixed to the traction wire fixing seat 6. Its cross-section adopts a polygonal design (preferably hexagonal), and the traction wire 12 is firmly fixed by mechanical clamping. This double fixing structure ensures that even if the connecting pin 7 accidentally falls off, the traction wire 12 can still remain fixed by the clamp tube 8, avoiding equipment damage. Throughout the operation, the two intersecting steering wheel adapters 9 move in coordination without interfering with each other within their respective mounting slots 501, achieving smooth pulling of the traction wire 12. This design is particularly suitable for long-distance pipeline operations, ensuring sufficient traction stroke while effectively avoiding motion interference, thus improving the accuracy and reliability of endoscope steering control.
[0023] Example 2 like Figure 1-5 As shown, this embodiment provides an endoscope having the drive structure of Embodiment 1. The traction wire 12 of the drive structure passes through the spring tube 15, wherein the spring tube 15 is mounted on the spring tube support 13.
[0024] Furthermore, it also includes an upper cover 2 and a lower cover 14 of the support body, wherein a spring tube support 13 is installed between the upper cover 2 and the lower cover 14 of the support body; an optical fiber 1 is also installed on the upper cover 2 of the support body.
[0025] Its outer casing has heat dissipation blocks 3 to meet heat dissipation requirements.
[0026] This invention uses a clamping tube to fix the traction wire, ensuring that the traction wire remains fixed even if the connecting pin falls off, thus preventing equipment damage; the mounting groove has varying depths, allowing for the pulling of longer traction wires.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
