Background
Arthroscopic technology originated in japan at the beginning of the 20 th century and was developed in countries such as the united states long after the 70's of the 20 th century. Arthroscopes have revolutionized the diagnosis and treatment of intra-articular diseases over the past decades and are now widely used clinically as a routine diagnostic and treatment means in osteoarticular surgery. The arthroscope can directly observe pathological changes compared with other examinations, has obvious superiority in a motion system, operates in a very small area and a channel under the condition of slightly interfering with the structure and the function of healthy tissues, inspects hidden parts which cannot be observed under the condition of direct vision, has strong direct vision and small wound, avoids the adhesion of a joint sliding device to the maximum extent, and is beneficial to the rapid recovery of the function. Currently, arthroscopic techniques are applied to a plurality of clinical aspects, mainly including diagnosis and treatment of meniscus injury, anterior and posterior cruciate ligament rupture, articular cartilage injury, intra-articular loose bodies, osteoarthritis and other diseases.
The joint cavity is a closed cavity gap formed by connecting joint surfaces at two ends of the joint capsule. The human joint clearance itself is narrow, which brings great operation difficulty to the arthroscopic surgery operator. At present, when the arthroscopic operation is carried out, the joint cavity gap is expanded by the pressure of liquid to obtain an operation space, but a good operation visual field is not obtained. In addition, the joint clearance of children is obviously narrower than that of adults, and becomes one of the biggest technical bottlenecks restricting the arthroscopic surgery of children and teenagers.
At present, various methods are clinically adopted to try to increase the joint clearance, a certain effect is achieved, but more clinical application problems still exist, and effective popularization cannot be achieved. The methods and disadvantages of attempting to increase joint space are mainly: a limb traction apparatus: complicated installation, traction injury, skin crush injury and other complications; (II) manual traction by an assistant: the persistence is difficult, and the labor is consumed; (III) intraoperative body position transformation: frequent transformation is required and the effect is limited.
