Description

Technical Field

[0001] The utility model belongs to the technical field of loose body removal medical equipment, in particular to a loose body removal device for clinical orthopedics. Background Art

[0002] Loose bodies refer to movable cartilage or osteochondral fragments in joints. In joints such as the knee or elbow, the convex surface of certain pressure epiphyses may undergo ischemic necrosis and exfoliation under repeated external forces, becoming free in the joint. They detach from their original positions and move back and forth in the joint, causing pain, swelling, and locking. In orthopedic clinics, surgery is required to clean loose bodies in the fossa. Two small incisions are made at the joint, and the arthroscope enters the joint through one incision. Physiological saline flows into the joint capsule along the cannula of the arthroscope, expanding the joint space. At the same time, the camera on the arthroscope clearly reflects the situation in the joint on the monitor, and then the grasper is extended into the joint through another incision to remove the loose body, allowing medical staff to accurately remove the loose body.

[0003] Currently, when removing loose bodies, most of them are oval in shape and have a relatively smooth surface, so when medical staff try to grasp them, the loose bodies will move around and are difficult to clamp. In addition, there is bone effusion and saline in the joints, so the grasper is more likely to slip when in contact with the loose body, increasing the difficulty of the operation. If the grasping fails, some bones may be touched, causing secondary damage. Utility Model Content
