Description

Endoscopic surgical instrument

The present invention relates to an endoscopic surgical instrument, and more particularly to an inventor of an endoscopic surgical instrument capable of stopping bleeding immediately during a surgical procedure without hindering surgery.

According to the common arthritis, there are two types: the first one is rheumatoid arthritis that may occur in any age group, and the second is degenerative arthritis mainly occurring in the elderly; and the joints are caused by long-term inflammation. Destruction with wear and tear, early joint trauma, may also cause degenerative arthritis after several years.

Most joints are mainly active. These joints have a synovial membrane as a cushion. When the joint is active, in order to avoid damage caused by chronic friction, synovial fluid can lubricate and protect the joint in the joint cavity. There is also a protective cartilage in the middle of the bone. Healthy cartilage allows the bone to slide relative to the other bone, and absorbs the impact energy brought about by physical movement to protect the joint from injury. However, after suffering from arthritis, the original protective function is lost, the synovial membrane in the joint becomes thicker, the lubrication is reduced, and the joint activity is deteriorated. Another reason is that the reduction of the joint fluid cavity also causes lubrication. cut back. In addition, the surface layer of the cartilage ruptures and is worn away, so that the bones located under the damaged cartilage rub against each other, causing joint pain, swelling, and loss of mobility. Inflamed conditions in these joints can cause joint pain and inconvenience.

The treatment of arthritis is mainly divided into two stages, the first is to reduce the pain and stiffness of the joints, and then to slow down the progress of the disease. There are many methods and drugs for treating arthritis, such as physical therapy, analgesics, non-steroidal anti-inflammatory agents (NSAIDs), hyaluronic acid injections [for degenerative arthritis], and for severely damaged joints, surgery can be considered. Such as arthroscopic procedures and even total artificial joint replacement surgery. Surgical treatment is mainly for the treatment of patients with obvious joint deformation, poor joint stability or joint damage. Commonly used surgical methods include arthroscopic resection, cartilage repair, tendon ligament repair or reconstruction, bone correction resection, and the like.
