Description

Technical Field

[0001] The utility model relates to the technical field related to medical instruments, in particular to a detachable cone head for a bone torture cone. Background Art

[0002] As people's demand for exercise increases, the number of patients with knee osteoarthritis is increasing. Among these patients, patients with early symptoms of osteoarthritis account for a large proportion. The knee cartilage damage of such patients is mostly I° or II° in terms of imaging manifestations and arthroscopic examination results, and there is no severe large-area cartilage defect. Therefore, arthroscopic subchondral bone microfracture technology can often be used for treatment to promote local cartilage repair and healing. Under arthroscopy, the instrument provides rotational power through the motor handle to drive the cone head with a limited position into the defective cartilage area, causing bleeding in the tissue of the cartilage area. During treatment, the cone head will collide with the bone, which will inevitably cause damage. After the damage, replacing the entire device will cause a lot of consumption.
