[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0022] like Figure 1 As shown, this utility model provides an arthroscopic device with a multi-angle adjustable lens, including a housing 1, an angle adjustment device 2 fixedly connected to the front of the housing 1, a housing 3 fixedly connected to the rear of the housing 1, and an observation device 4 fixedly connected to the rear of the housing 3. This device achieves dynamic adjustment of the lens angle and precise control of the irrigation and aspiration position through the linkage of the angle adjustment device 2, the transmission mechanism of the housing 1 and the housing 3, the camera module 42 and the fluid pipeline system, thus solving the problems of limited field of view and insufficient irrigation and aspiration flexibility of traditional arthroscopy.
[0023] like Figure 2 As shown, this utility model provides a technical solution: the angle adjustment device 2 includes a rotating base 21 and a silicone sleeve 25. A base 26 is rotatably connected to the rear of the rotating base 21. Two hinge bases 22 are fixedly connected inside the rotating base 21. The two hinge bases 22 are symmetrically distributed on the left and right sides of the rotating base 21. The hinge base 22 on the right side of the rotating base 21 is rotatably connected to a connecting rod 1 23, and the hinge base 22 on the left side of the rotating base 21 is rotatably connected to a connecting rod 3 27. The other ends of the connecting rod 3 27 and the connecting rod 1 23 are respectively rotatably connected to a connecting rod 4 28 and a connecting rod 2. 24. The front and rear ends of the silicone sleeve 25 are fixedly connected to the rotating seat 21 and the base 26 respectively. The rear end of the base 26 is fixedly connected to the housing 1. The slider 29 is connected to the connecting rod 24. When the rotating handle 210 is turned to the left, the rotating handle 210 will drive the slider 212 to move backward. At the same time, the slider 212 will pull the rotating seat 21 to the left through the connecting rod 4 28, the connecting rod 3 27 and the connected hinge base 22. Meanwhile, the rotating seat 21 will pull the connecting rod 24 through the hinge base 22 on the other side and the connecting rod 1 23, thereby causing the slider 29 to slide forward.
[0024] like Figure 3 As shown, this utility model provides a technical solution: a fixed base 41 is fixedly connected inside the rotating base 21. A camera module 42 and a beam guide 45 are fixedly connected inside the fixed base 41. A fixed base 41 and an infusion tube 46 are fixedly connected to the right side of the camera module 42 and the beam guide 45, respectively. The camera module 42 and the beam guide 45 are located on the upper and lower sides of the connecting rod 23, respectively. A fixed base 44 is fixedly connected inside the housing 1. The fixed base 44 is fixedly connected to the camera module 42, the suction tube 43, the beam guide 45, and the infusion tube 46. The fixed base 44 is slidably connected to the connecting rod 24 and the connecting rod 48. When observing into the joint, the beam guide connector at the rear of the housing 23 is connected to an external cold light source. The light is transmitted to the front end of the rotating base 21 through the beam guide 45, illuminating the inside of the joint cavity. At the same time, the camera module fixed inside the rotating base 21 collects real-time images and transmits them to an external display through the signal interface at the rear of the housing 23, realizing visualization of the structure under the microscope.
[0025] like Figure 4As shown, this utility model provides a technical solution: a fixed base 47 is fixedly connected to the rear of the housing 1, and the fixed base 47 is slidably connected to the connecting rod 28 and the connecting rod 24. Two guide rails 213 are fixedly connected inside the housing 23, and the two guide rails 213 are symmetrically distributed on the left and right sides of the housing 23. The guide rail 213 on the left side of the housing 23 is slidably connected to the connecting rod 28 and a slider 212 is slidably connected above it. The guide rail 213 on the right side of the housing 23 is slidably connected to the connecting rod 24 and a slider 29 is slidably connected above the connecting rod 24. Slider 212 and slider 29 are fixedly connected to the connecting rod 28 and the connecting rod 24, respectively. A gear 211 is rotatably connected between slider 29 and slider 212 in the housing 23, and a rotating handle 210 is rotatably connected to its outer side. 211 and the rotating handle 210 are fixedly connected. The inner sides of slider 1 29 and slider 2 212 are both fixedly connected to racks and mesh with gear 211. The bottom of housing 2 3 is fixedly connected to a beam guide connector and fixedly connected to the end of beam guide 45. The fixed base 47 is fixedly connected to camera module 42, suction tube 43, beam guide 45 and infusion tube 46. When the rotating handle 210 is turned to the right, gear 211 rotates clockwise, driving slider 1 29 to move backward. Through connecting rod 24 and connecting rod 23, the rotating base 21 is pulled to the right. Slider 2 212 moves forward and disengages from gear meshing. The rotating base 21 deflects to the right to achieve right-side field of view. When the rotating handle 210 is reset, the racks of slider 1 29 and slider 2 212 mesh with gear 211. The rotating base 21 is in the middle position and the field of view is facing forward.
[0026] like Figure 5 As shown, this utility model provides a technical solution: a fixed base 48 is fixedly connected to the rear of the housing 2 3, and two quick-connect pipe joints 49 are fixedly connected to the rear of the fixed base 5 48. The ends of the suction pipe 43 and the infusion pipe 46 are respectively fixedly connected to one quick-connect pipe joint 49. The end of the camera module 42 extends out of the fixed base 5 48. In use, the ends of the infusion pipe 46 and the suction pipe 43 are connected to an external infusion pump and a negative pressure suction device through the quick-connect pipe joints 49. The infusion pipe 46 and the suction pipe 43 will rotate synchronously with the rotating base 21. When the rotating base deflects to the left / right, the opening direction of the front end of the infusion pipe 46 and the suction pipe 43 is adjusted accordingly to achieve directional infusion and suction.
[0027] The working principle of this arthroscopic device with a multi-angle adjustable lens will be explained in detail below.
[0028] like Figure 1-5As shown, gear 211 inside housing 210 is fixedly connected to rotating handle 210. The racks on the inner sides of slider 1 29 and slider 2 212 mesh with gear 211. The rotating handle drives the gear to rotate, causing slider 1 29 and slider 2 212 to slide in the opposite direction along guide rail 1 213. At the same time, slider 1 29 is connected to connecting rod 24, and slider 2 212 is connected to connecting rod 4 28. The two form a four-bar linkage with connecting rod 1 23 and connecting rod 3 27 on both sides of rotating base 21 through hinge base 22. When rotating handle 210 is turned to the left, gear 211 rotates counterclockwise. When the rotating handle 210 is turned to the right, the gear 211 rotates clockwise, driving slider 212 to move backward. This, in turn, pulls the rotating base 21 to the left via connecting rods 28 and 27. Simultaneously, slider 29 moves forward and disengages from the gear, preventing gear jamming due to the speed difference between the two sliders. The rotating base 21 drives the front-end camera module 42 and the irrigation / suction pipe to rotate to the left, enabling left-side field of view. When the rotating handle 210 is turned to the right, gear 211 rotates clockwise, driving slider 29 to move backward. This, in turn, pulls the rotating base 21 to the right via connecting rods 24 and 23. 2. Moving forward disengages the gear, and the rotating seat 21 deflects to the right, enabling right-side viewing. When the rotating handle 210 returns to its original position, the racks of slider 1 29 and slider 2 212 engage with gear 211, placing the rotating seat 21 in the neutral position with the field of view facing forward. When observing the joint interior, the beam guide connector at the rear of housing 2 3 connects to an external cold light source. Light is transmitted through beam guide 45 to the front end of the rotating seat 21, illuminating the joint cavity. Simultaneously, the camera module fixed inside the rotating seat 21 acquires real-time images, which are transmitted to the external light source via the signal interface at the rear of housing 2 3. The display screen enables visualization of the microscopic structure. Then, the ends of the infusion tube 46 and the suction tube 43 are connected to the external infusion pump and the negative pressure suction device through the quick-connect fitting 49. The infusion tube 46 and the suction tube 43 will rotate synchronously with the rotating seat 21. When the rotating seat deflects to the left or right, the opening direction of the front end of the infusion tube 46 and the suction tube 43 will be adjusted accordingly to achieve directional infusion and suction. The fixed seat 3 44 and the fixed seat 47 ensure that the infusion tube 46 and the suction tube 43 remain stable during the angle adjustment process, and avoid the infusion tube 46 and the suction tube 43 from twisting or falling off due to rotation.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
