Abstract
Description
Technical Field
[0001] This invention relates to the field of mobile frames, and more particularly to a mobile frame for orthopedic arthroscopy. Background Technology
[0002] An arthroscopy is a rod-shaped optical instrument, approximately 5 mm in diameter, used to observe the internal structures of a joint and is an endoscope for diagnosing and treating joint diseases. This instrument has been widely used since 1970. An arthroscopy has a lens at the end of a thin tube. When this tube is inserted into the joint, the internal structures are displayed on a monitor. Therefore, the internal structures of the joint can be directly observed. Arthroscopy is not only used for disease diagnosis but has also been widely used for the treatment of joint diseases. Arthroscopic surgery is a minimally invasive procedure, initially applied primarily to the knee joint, and later extended to the hip, shoulder, ankle, elbow, and small joints such as the fingers.
[0003] The power supply for arthroscopy is typically mounted on a dedicated mobile frame. Existing frames generally have 3 to 6 layers. The necessary equipment is placed on the frame, and after connecting the equipment and power supply, the existing frames are all multi-layered. When changing instruments, medical staff need to bend over. Bending over can easily damage the sterile area during surgery, increases the difficulty of the surgeon's work, and sometimes one hand is performing surgery while the other needs to retrieve instruments; bending over can easily cause body movement, affecting the surgical outcome.
[0004] Therefore, it is necessary to invent a movable frame for orthopedic arthroscopy to solve the above problems. Summary of the Invention
