Description

Cartilage puncture auxiliary device

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to cartilage puncture auxiliary device.

Background

The cartilage puncture has wide orthopedic clinical significance, and the puncture needle penetrates into a body cavity to extract secretion, or injects gas or contrast agent into the body cavity to perform contrast examination, or injects medicaments into the body cavity, so that the application range is wide. Taking contrast agent as an example, it is a new technique in modern imaging diagnosis for diagnosing bone and cartilage tumors. The puncture biopsy of the skin and bone is an important diagnosis method for the diseases of the system, and the technology is developed on the basis of the puncture biopsy of the bone. Bone punch biopsy (needle biopsy), also known as core biopsy.

For example, CT guided biopsy for bone diseases, its application and accuracy analysis, percutaneous biopsy for bone tissue aspiration, and its significance in disease diagnosis and treatment. A summary analysis was performed on 137 cases of CT guided bone biopsy. The puncture rate of the lesion is 100 percent, and the pathological result of the needle biopsy is clearly diagnosed in 122 cases, while the diagnosis is not clear or misdiagnosed in 15 cases. The total diagnosis accuracy of the puncture biopsy is 89.0%, wherein the diagnosis accuracy of the metastatic cancer, the primary malignant tumor and the benign lesion is 95.8%, 85.7% and 85.1% respectively. The percutaneous bone tissue aspiration biopsy under the guidance of CT has small wound, high diagnosis accuracy and few complications, is a safe and effective diagnosis method, and has important significance for guiding treatment.
