Description

Medical orthopedics is clinical with episome extractor

Technical Field

The utility model relates to a trip body extractor technical field especially relates to a clinical trip body extractor of using of medical orthopedics.

Background

The free form is also known as: in the joint of the articular rat, in the knee or elbow and other joints, the convex surface of some pressure epiphyses can be subjected to ischemic necrosis and denudation under the repeated action of external force, and can be dissociated in the joint, so that the articular rat is called as denudation osteochondritis (articular episome). In addition, the free body undergoes synovium metaplasia, and chondrocytes or osteocytes can be formed for continuous growth. The episome moves within the joint, also known as an arthritic mouse.

Because the episome is very strong in the free nature of the aquatic, therefore when ordinary operating forceps are close to the episome, can cause the episome to move because of the vibrations that the operating forceps move and bring, make the episome move out of the field of vision of arthroscope, difficult quilt is cliied, and when taking out the small episome, need take out the extractor and reinsert repeatedly, cause the repeated misery to the patient, for this reason we propose a clinical episome extractor of medical orthopedics, solve the above-mentioned problem.
