Technical Field

The invention relates to the technical field of medical auxiliary equipment, in particular to a medical free body extractor for orthopedics clinic.

Background

In joints such as knee or elbow, the convex surface of some pressure epiphyses can be subjected to ischemic necrosis and exfoliation under the repeated action of external force, and the episome is called exfoliative osteochondritis (articular episome). In addition, the free body undergoes synovium metaplasia, and chondrocytes or osteocytes can be formed for continuous growth. In addition, the loose body of the knee joint often has the joint interlocking phenomenon, and the small loose body is clamped between the joint surfaces, so the sudden joint interlocking phenomenon occurs. When present, the patient can experience severe pain and the interlock position is often not fixed. The patient may experience joint swelling, fluid accumulation, and weakness of the knee due to mechanical stimulation of the periosteum, or may touch the movable mass due to free body migrating to the superficial area. In addition, when the interlock is unlocked, the patient may hear or feel a loud sound, a wrong feeling, or some may kneel and fall, and therefore, the free body needs to be taken out of the joint.

Because the episome is very strong in the aquatic episome, consequently when ordinary operating forceps were close to the episome, can arouse the swimming of episome because of the vibrations that the operating forceps removed the bring, make the episome shift out in the field of vision of arthroscope, difficult quilt is cliied, and when taking out little episome, take out the extractor reinsertion repeatedly, cause the misery to patient, consequently, how to improve the episome extractor of prior art, become the technical problem that technical staff in the field had a great deal of solution.
