[0002] An arthroscope is a rod-shaped optical instrument for observing the internal structure of a joint. It is an endoscope used to diagnose and treat joint diseases. The arthroscope has a lens at the end of a thin tube. When the thin tube is inserted into the joint, the internal structure of the joint will be displayed on the monitor, allowing the doctor to clearly understand the specific condition of the patient's joint for diagnosis and surgery.

[0003] During arthroscopic surgery, the doctor usually holds the arthroscope in one hand and other contracting instruments in the other hand to perform surgery on the patient. It is difficult to perform surgery with one hand, which is not conducive to the doctor performing surgery on the patient. Moreover, when observing the joints with the arthroscope, it is easy for the arthroscope to rub and collide with the patient's joints. It is also difficult to make subtle adjustments to the arthroscope to observe different positions of the joints, which is not conducive to the operation. In addition, as the operation progresses, the patient's joints cannot be further fixed during the adjustment of the arthroscope. If the patient moves, the operation may go wrong.

Since the threaded block 9 cannot rotate, the threaded block 9 moves up and down under the action of the thread when the threaded rod 6 rotates, driving the mounting frame 10 and the arthroscope 3 to move together, so that the arthroscope 3 is moved to the patient's joint to observe the damaged part of the joint, so as to facilitate the doctor to perform surgery. Moreover, the arthroscope 3 is mounted on the mounting frame 10 without the need to be held, thus freeing one hand of the doctor, so that the doctor can perform surgery more conveniently.

When the connecting ratchet 710 rotates, the ratchet of the connecting ratchet 710 squeezes the corresponding connecting ratchet 79 to make it move under force. As the connecting ratchet 710 rotates continuously, the connecting ratchet 79 is also always in a state of force, and when the connecting ratchet 79 moves under force, it drives the connecting ring 78 to rotate, so that the connecting shaft 72 rotates accordingly, and the rotation of the connecting shaft 72 causes the connecting roller 73 to rotate, tightens the fixing belt 13 to the connecting roller 73, and further fixes the fixing belt 13 and the patient's thigh; During the rotation of the threaded rod 6, under the action of the second belt transmission structure 77, the fixed worm 76 will rotate accordingly, so that the fixed worm wheel 75 meshing with the fixed worm 76 rotates, so that the rotating shaft 74 fixedly connected to the fixed worm wheel 75 rotates, driving the connecting ratchet 710 installed on the rotating shaft 74 to rotate, tightening the fixing belt 13 onto the connecting roller 73, so that the fixing belt 13 is further tightened, and the fixing belt 13 and the patient's thigh are further fixed; The connecting ratchet 710 is installed on both sides of the rotating shaft 74, and the connecting ratchet 710 on both sides is installed oppositely, that is, the ratchet directions of the connecting ratchet 710 on both sides are opposite, and the installation direction of the corresponding connecting ratchet 79 is also opposite to the rotation direction of the one-way bearing, so when the connecting ratchet 710 rotates forward or reverse, the connecting ratchet 710 and the corresponding connecting ratchet 79 are in a meshing state; A first belt rotating structure 8 is installed between the threaded rod 6 and the arthroscope 3, and the rotating wheel 1 of the first belt rotating structure 8 is slidably connected to the arthroscope 3, and the rotating wheel 2 of the first belt rotating structure 8 is rotatably connected to the threaded block 9, to ensure that the belt transmission structure 8 will not have movement interference when the mounting frame 10 and the arthroscope 3 move, a groove is opened on the rotating wheel 2, and an adjusting rod 16 is slidably connected to the groove, the adjusting rod 16 passes through the inner wall of the groove and is fixedly connected to a connecting block 17, and a sliding groove 11 matching the connecting block 17 is opened on the side wall of the threaded rod 6, the adjusting rod 16 is adjusted to move the connecting block 17, and the connecting block 17 is inserted into the sliding groove 11, at this time, the rotation of the threaded rod 6 can drive the rotating wheel 2 to rotate, thereby rotating the first belt rotating structure 8, driving the arthroscope 3 to rotate, and adjusting the angle of the arthroscope 3; One side of the support plate 1 is fixedly connected to the fixed bracket 2, and the other side of the support plate 1 is connected to the fixed bracket 2 in an arc-shaped sliding manner. The patient's thigh is placed on the side where the support plate 1 is fixedly connected to the fixed bracket 2, and the calf is placed on the other side. At the same time, the support plate 1 fixedly connected to the fixed bracket 2 is rotatably connected to the mounting shaft, and the support plate 1 on the other side is fixedly connected to the mounting shaft. Therefore, the rotation of the mounting shaft will drive the support plate 1 on the other side to rotate, that is, the support plate 1 used to support the calf rotates; A fixing slot 14 is formed at the top of the thread block 9, and a fixing tooth 15 matching the fixing slot 14 is fixedly connected to the side wall of the mounting frame 10. The mounting frame 10 and the thread block 9 are fixedly connected together through the fixing slot 14 and the fixing tooth 15. The mounting frame 10 can be separated by lifting it upwards. The fixing belt 13 is made of an elastic belt; a rotating knob is rotatably connected to the support plate 1, and the rotating knob is fixedly connected to the mounting shaft. Rotating the rotating knob can rotate the mounting shaft, thereby driving the support plate 1 slidingly connected to the fixed bracket 2 to rotate, and adjusting the angle between the support plates 1. According to the different joint injuries of the patient, the angle of fixation of the patient's legs is adjusted.

[0017] In the present invention, the rotating knob is first turned to rotate the mounting shaft, thereby driving the support plate 1 slidably connected to the fixed bracket 2 to rotate, and the angle between the support plates 1 is adjusted. According to different joint injuries of the patient, the angle of fixation of the patient's leg is adjusted to facilitate the support of the patient's leg by the support plate 1. Then, the patient's thigh is placed on the support plate 1 on one side, and the calf is placed on the support plate 1 on the other side. The patient's thigh and calf are fixed by the fixing belt 13, and then the mounting frame 10 and the arthroscope 3 are lifted, and the arthroscope 3 is rotated to move to the position of the joint, and then the mounting frame 10 and the threaded block 9 are fixedly connected together through the fixing slot 14 and the fixing tooth 15. At this time, the movement of the threaded block 9 can drive the mounting frame 10 and the arthroscope 3 to move; The rotating block 5 is rotated to rotate the threaded rod 6. Since the threaded block 9 cannot rotate, the threaded block 9 will move up and down when the threaded rod 6 rotates under the action of the thread, driving the mounting frame 10 and the arthroscope 3 to move together, so that the arthroscope 3 is moved to the patient's joint to observe the damaged part of the joint, so as to facilitate the doctor to perform surgery. At the same time, the arthroscope 3 can be adjusted by the threaded rod 6 and other structures, so that the arthroscope 3 can be moved slightly, and the moving distance is more accurate than when it is manually held, and it is not easy to cause friction and collision between the arthroscope 3 and the patient's joint, so that the arthroscope 3 and the patient's joint are protected. Moreover, the arthroscope 3 is installed on the mounting frame 10 without the need to be held by hand, thereby freeing one hand of the doctor, so that the doctor can perform surgery more conveniently. At the same time, during the rotation of the threaded rod 6, under the action of the second belt transmission structure 77, the fixed worm 76 will rotate accordingly, so that the fixed worm wheel 75 meshing with the fixed worm 76 rotates, so that the rotating shaft 74 fixedly connected to the fixed worm wheel 75 rotates, driving the connecting ratchet 710 installed on the rotating shaft 74 to rotate, tightening the fixing belt 13 onto the connecting roller 73, so that the fixing belt 13 is further tightened, and the fixing belt 13 and the patient's thigh are further fixed, so as to avoid the patient's thigh from moving and being injured when the arthroscope 3 is adjusted during the operation; In addition, the adjusting rod 16 is moved to move the connecting block 17 so that the connecting block 17 is inserted into the sliding slot 11. At this time, the rotation of the threaded rod 6 can drive the rotating wheel 2 to rotate, thereby rotating the first belt rotating structure 8, driving the arthroscope 3 to rotate, and adjusting the angle of the arthroscope 3. Since the moving distance of one circle of the thread is very small, the moving distance can be ignored when adjusting the angle of the arthroscope 3. After adjusting the angle of the arthroscope 3, other positions of the joint can be observed, which is beneficial to the doctor's surgery.
