Description

Technical Field

[0001] This utility model relates to the field of endoscope auxiliary equipment, specifically to an auxiliary camera mechanism for endoscopes. Background Technology

[0002] Medical endoscope systems are medical devices that integrate medicine, optics, ergonomics, precision mechanics, modern electronics, and computer software to provide doctors with images of the internal anatomical structure of the human body during clinical examination, diagnosis, and treatment. Endoscopic camera systems are known as "the doctor's eyes." The imaging method and quality of the camera system determine the user's experience. Typically, the human eye can perceive a continuous image at a speed between 24 frames per second and 36 frames per second. However, a lower frame rate often results in lower real-time image clarity than static images due to visual persistence.

[0003] Most endoscopic camera systems on the market currently operate at 30, 50, or 60 frames per second (fps). While these fps meet the minimum frame rate that the human eye can perceive, they still lack continuity. This is especially true for rapid movements and smoke-filled scenes during endoscopic surgery. In minimally invasive surgery, instruments often move rapidly, pulling on tissues. At refresh rates of 30 to 60 fps, the trailing effect is more pronounced, resulting in blurred images and even visual fatigue for the user. This may introduce risks during prolonged surgeries.

[0004] According to the existing patent document CN211796357U, an auxiliary camera mechanism for an endoscope and an endoscope are disclosed. The auxiliary camera mechanism is used to be installed on the main tube of the endoscope. The auxiliary camera mechanism includes a connecting component and a camera. The connecting component is used to connect to the main tube of the endoscope, and the camera is disposed on the connecting component. This technical solution is easy to install on the main tube of the endoscope to facilitate real-time monitoring of the area behind the lens, avoiding "accidental damage" to nerves, blood vessels and important structures behind the lens caused by instruments constantly entering and exiting the surgical area. However, although the above technical solution achieves monitoring behind the lens, it cannot achieve lens flipping and defogging during monitoring, which is inconvenient to use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary camera mechanism for endoscopes to solve the problems mentioned in the background art. This utility model has a novel structure. When in use, the cable drives the rotating column to rotate, and the rotating column drives the camera to rotate to achieve the flipping of the lens direction. At the same time as the camera flips, the cleaning block contacts the camera to perform defogging treatment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary camera mechanism for an endoscope, comprising an endoscope, a support tube fixed to the endoscope, an endoscope lens fixedly mounted at one end of the support tube, an auxiliary component movably mounted on the support tube, a cable mounted on the auxiliary component, the auxiliary component including a protective tube, a fixing seat fixed inside the protective tube, an opening in the fixing seat, a limiting wheel movably mounted inside the opening, the support tube movably mounted inside the opening, and the limiting wheel movably mounted on the side of the support tube.

[0007] Furthermore, a support plate is fixed inside the opening, a limit groove is formed on the support plate, and a tension mechanism is fixed inside the limit groove.

[0008] Furthermore, one end of the tension mechanism is fixed with a support column, and one end of the support column is rotatably mounted on a limit wheel.

[0009] Furthermore, the fixing base has mounting holes and cavities respectively, a fixing plate is fixed inside the cavity, and a fixing tube is fixed on the fixing plate.

[0010] Furthermore, a rotating column is rotatably installed inside the fixed tube. The rotating column is connected to one end of the cable. A torque mechanism is fixed on the rotating column, and one end of the torque mechanism is fixed to the fixed tube.

[0011] Furthermore, a sealing ring is fixed on the inner wall of the fixed tube, a camera is fixed at one end of the rotating column, a cleaning block is installed on the side of the camera, and the cleaning block is fixed on the inner wall of the cavity.

[0012] The beneficial effects of this utility model are:

[0013] 1. The auxiliary camera mechanism of this endoscope, when in use, the cable drives the rotating column to rotate, the rotating column drives the camera to rotate to achieve the flipping of the lens direction, and at the same time the camera flips, the cleaning block contacts the camera to perform defogging treatment.

[0014] 2. The auxiliary camera mechanism of this endoscope has a limiting wheel that is clamped onto the support tube by the push of the support column. The support column can only move back and forth on the limiting wheel, thus effectively preventing the lens from becoming blurry when the fixed seat and protective tube rotate on the support tube during use.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: an auxiliary camera mechanism for an endoscope, including an endoscope 1, a support tube 2 fixed on the endoscope 1, an endoscope lens 5 fixedly installed at one end of the support tube 2, an auxiliary component 3 movably installed on the support tube 2, a cable 4 installed on the auxiliary component 3, the auxiliary component 3 including a protective tube 6, a fixing seat 7 fixed inside the protective tube 6, an opening 8 on the fixing seat 7, a limiting wheel 11 movably installed inside the opening 8, the support tube 2 movably installed inside the opening 8, the limiting wheel 11 movably installed on the side of the support tube 2, a support plate 9 fixed inside the opening 8, a limiting groove 19 on the support plate 9, a tension mechanism 20 fixed inside the limiting groove 19, the tension mechanism 20 being a tension spring, the tension spring driving the support column 10 to move inward, the support column 10 clamping and limiting the support tube 2 through the limiting wheel 11.

[0023] In this embodiment, one end of the tension mechanism 20 is fixed with a support column 10, and one end of the support column 10 is rotatably mounted on a limiting wheel 11. The fixed base 7 has a mounting hole 22 and a cavity 21 respectively. A fixed plate 12 is fixed inside the cavity 21, and a fixed tube 13 is fixed on the fixed plate 12. A rotating column 15 is rotatably mounted inside the fixed tube 13. The rotating column 15 is connected to one end of the cable 4. A torque mechanism 14 is fixed on the rotating column 15. One end of the torque mechanism 14 is fixed to the fixed tube 13. A sealing ring 16 is fixed on the inner wall of the fixed tube 13. A camera 17 is fixed to one end of the rotating column 15. A cleaning block 18 is installed on the side of the camera 17. The cleaning block 18 is fixed on the inner wall of the cavity 21. The torque mechanism 14 is a torsion spring. When the rotating column 15 rotates, the torsion spring is compressed. After compression, the torque mechanism 14 drives the rotating column 15 to return to its original position, adjusting the illumination direction of the camera 17.

[0024] In use, the mounting base 7 is fitted onto the endoscope 1 through the opening 8 from one end of the support tube 2. During installation, pressing the protective tube 6 pushes the mounting base 7 to move it. When the mounting base 7 is stationary, the pulling mechanism 20 drives the limiting wheel 11 to simultaneously press inward, limiting the positions of the protective tube 6 and the mounting base 7. The external cable 4 is connected to an external display device, and the image transmitted from the camera 17 is displayed on the display device. In use, the rotating column 15 is rotated by pulling the cable 4. The rotation of the rotating column 15 deforms the torque mechanism 14, causing it to rotate. After the column 15 loses tension, the torque mechanism 14 drives the rotating column 15 to rotate back to its original position. When the rotating column 15 rotates, the camera 17 rotates 180 degrees, changing the shooting position of the camera 17 by 180 degrees. After the position of the camera 17 changes, it can achieve auxiliary shooting from different positions. When the camera 17 rotates, one end of the camera 17 contacts the cleaning block 18. The cleaning block 18 can scrape off the fog generated on the camera 17, which facilitates the clarity of the subsequent shooting. The camera 17 can be used for high refresh rate shooting, adaptive high refresh rate, high frame rate transient, blur recovery and real-time image classification processing.
