Description

[0001] MEDICAL ARTHROSCOPY AND CANNULA THEREFOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical arthroscope and a cannula for the same, and more particularly, to a medical arthroscope and a cannula for inserting the same into a joint, .

Generally, the knee joint refers to a joint formed by the femur, the tibia, and the patella adjacent to the knee, and the knee joint is referred to in orthopedic surgery .

These knee joints are both the left and right sides of the human body, and are the key joints that play an important role in supporting the weight of the human body and exercising the legs such as walking and running through the joints.

In addition, the knee joint is the most vulnerable joint because it is frequently used, has a lot of room for crowdedness, is affected by various diseases, is unstable in its bony structure, .

Particularly, since the knee joint is used for almost every activity of the bridge and plays a very important role, if the joint is in trouble, the patient is greatly restricted in daily life.

These knee joint lesions are more difficult to diagnose than other joints. The reason for this is that simple radiographies can not diagnose ligament injuries or rupture of the cartilage.

However, MRI (Magnetic Resonance Imaging) test has been helpful in the accurate diagnosis of soft tissue injuries of ligament, paralyzed cartilage, and knee joint. However, the cost of testing is high, Its use is limited.

Therefore, a technique using arthroscopy based on an endoscopic device has been developed through research and development to diagnose accurate lesion of the knee at a low cost, and the development of arthroscope has revolutionized diagnosis and treatment of the knee come.

According to these arthroscopes, it is possible to perform all kinds of operations within the joint through several small holes without cutting the joints, as well as performing an accurate diagnosis by inserting it into the joint and looking directly at the lesion in the joint.

For example, knee arthroplasty using arthroscopy can be used for loose body removal, meniscectomy or meniscal repair, synovectomy, reconstruction of cruciate ligament, ligaments, and the like.

Because these arthroscopes do not incise joints, there are many advantages such as less pain after surgery, faster recovery of joint motion, fewer surgical complications, and reduced cost of treatment. In addition to knee joints, The use thereof is gradually increasing.

These arthroscopes can be used for special imaging (CT, MRI) by inserting an arthroscope equipped with a special small camera into the joint using a small-diameter hole without cutting the affected part during the procedure and then observing the inside of the joint through a monitor Even if the lesion is not detected, and at the same time allows the surgeon to perform the operation.

However, according to the conventional arthroscope as described above, since the camera for photographing the operation site and the monitor for displaying the image are connected to each other through a cable, the degree of freedom of movement of the arthroscope is reduced.

In particular, according to the conventional arthroscope, as the tip of a cannula on which a lens of a camera is mounted is opened, blood or soft tissues flow into the cannula during surgery to cover the camera lens, The entire view is blocked.

Furthermore, there is a disadvantage that the lens and the camera are damaged through contact with blood or soft tissues flowing into the cannula.

In addition, according to the conventional arthroscope, since the distal end of the cannula is opened and the camera lens and the camera and the operation site communicate directly with the inside of the joint, the operation part is infected through the lens and the camera, .

Furthermore, high-pressure sterilization is frequently performed at a high temperature in order to prevent such infection at the time of the procedure, and such frequent high-pressure sterilization disadvantageously adversely affects the lens and the camera, resulting in shortening the overall durability of the arthroscope.

Furthermore, since conventional arthroscopic diagnosis and procedures require the insertion of a coarse arthroscope into the joint through the skin and joints, general anesthesia or spinal anesthesia must be performed in the receiving room, Loss occurs.

Accordingly, the research and development aiming at providing the arthroscope to provide the convenience of the operation while preventing the arthroscopic function, the infectious accident occurring during the procedure, and the quicker and more accurate explanation to the patient, As well.

 The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.
