Description

A cartilage puncture aid device

technical field

The utility model belongs to the field of medical equipment, in particular to a cartilage puncture auxiliary device.

Background technique

Cartilage puncture has a wide range of orthopedic clinical significance. The puncture needle is inserted into the body cavity to extract secretions, or inject gas or contrast agent into the body cavity for contrast examination, or inject drugs into the body cavity. The device has a wide range of applications. Taking contrast agent as an example, many new technologies in modern imaging diagnosis are used in the diagnosis of bone and cartilage tumors. Bone biopsy is an important diagnostic method for this systemic disease, and this technique is developed on the basis of bone biopsy. Bone biopsy (needlebiopsy), also known as core biopsy.

For example, "Application and Accuracy Analysis of CT-Guided Needle Biopsy in the Diagnosis of Bone Diseases", the practicability of percutaneous bone biopsy and its significance for disease diagnosis and treatment. A total of 137 cases of CT-guided bone biopsy were analyzed. The puncture rate of the lesions was 100%, 122 cases were diagnosed clearly by the biopsy results, and 15 cases were not clearly diagnosed or misdiagnosed. The overall diagnostic accuracy of needle biopsy was 89.0%, and the diagnostic accuracy of metastatic carcinoma, primary malignant tumor and benign lesions were 95.8%, 85.7% and 85.1%, respectively. CT-guided percutaneous bone biopsy is a safe and effective diagnostic method with less trauma, high diagnostic accuracy and fewer complications, which is of great significance for guiding treatment.

Therefore, it is necessary to design a special aid for cartilage puncture.
