Description

Technical field:

[0001] The utility model relates to the field of auxiliary treatment of bone cysts, in particular to a drug treatment device for bone cysts. Background technology:

[0002] Bone cysts usually refer to simple bone cysts, which are benign tumors common in children and adolescents. They often occur in the metaphysis of long bones such as the femur and humerus. They have an insidious onset, localized lesions, and a high recurrence rate. Injecting hormones such as methylprednisolone acetate into the cyst cavity is a common way to treat bone cysts. Compared with traditional open surgery to scrape the cyst wall, this method has the advantages of less trauma and less cost. However, the recurrence rate of bone cysts after hormone injection treatment is high, and multiple surgical punctures are usually required for multiple courses of hormone injections, which increases the surgical pain and family burden of patients with recurrent or prolonged lesions.

[0003] The current hormone treatment of bone cysts needs to be improved due to the disadvantage of repeated surgical puncture. It is necessary to invent a device with less trauma and repeated drainage and injection to improve the current hormone treatment mode of bone cysts and to create a precedent for the application of similar technologies in bone tumor basin diseases. Therefore, a drug treatment device for bone cysts is proposed. Utility model content:
