The present disclosure relates to an artificial joint integrated management device, and more particularly to an artificial joint integrated management device and application that find an artificial joint suitable for surgery and facilitate the supply of the artificial joint.
Recently, as the history of orthopedic and surgical operations has increased, the frequency of reoperation is increasing. In particular, as more than 30 years have passed since the introduction of joint replacement surgery, the frequency of reoperations gradually increases. These surgeries are characterized by a high degree of difficulty due to a bone loss and a loss of surrounding muscles, and a poor surgical prognosis. When replacing an artificial joint in this reoperation, one of the most important things is to identify a type of artificial joint that was used before. An artificial joint applied to the hip joint consists of a combination of the acetabulum and the femur. In most patients, surgery is completed only by replacing the artificial joint corresponding to the acetabulum, but it is important to identify a type of artificial joint applied to the femur in order to determine the combination between the femur and the acetabulum. However, since all surgical records that have passed 30 years have been discarded, it is very difficult to identify the type of artificial joint, and thus a surgical method is determined by an experience of long-term instrument company employees.
In this case, there is provided a method of comparing one x-ray picture with characteristics of various artificial joints, predicting an artificial joint to be used in surgery, and ordering and using the predicted artificial joint from the vendor.
However, in this case, there is a risk that the surgery will fail because a type of predicted artificial joint is not accurate. In addition, an inventory shortage of the predicted artificial joint causes the use of suboptimal artificial joint or delay in surgery.
One aspect of the present disclosure provides an artificial joint integrated management device and application capable of accurately finding suitable artificial joints required during surgery.
Another aspect of the present disclosure provides an artificial joint integrated management device and application capable of facilitating supply and demand of artificial joints.
In one aspect of the present disclosure, there is provided an artificial joint integrated management device comprising an artificial joint matching unit configured to identify an artificial joint matched to a specific medical image inputted through a machine learning model and provide information on the artificial joint; and an inventory management unit configured to provide information on an inventory status of vendors for selected artificial joints.
The artificial joint matching unit may include a machine learning unit configured to learn a relationship between a plurality of medical images and types of applicable artificial joints based on a database, wherein the database includes the plurality of medical images and data on artificial joints matched to the plurality of medical images; and an artificial joint information providing unit configured to provide information on the artificial joint suitable for the specific medical image based on the machine learning model generated by the machine learning unit.
The artificial joint integrated management device may further comprise a demand information providing unit configured to provide demand status information for the artificial joint.
The inventory management unit may include an inventory status management unit configured to provide an inventory possession status of the vendors for the artificial joint; and a demand status management unit configured to provide a demand status of the vendors for the artificial joint.
The inventory status management unit and the demand status management unit may be configured to be updated.
In another aspect of the present disclosure, there is provided an application stored in a storage medium that selects an artificial joint suitable for a specific medical image and provides an inventory status of selected artificial joints, the application comprising inputting the specific medical image; providing information on the artificial joint suitable for the specific medical image based on a machine learning model, wherein the machine learning model is a machine learned based on a plurality of medical images and data on artificial joints matched to the plurality of medical images; and providing information on an inventory status of a plurality of vendors for the provided artificial joint.
