Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a percutaneous tissue puncture guide plate and a construction method thereof.
Background
Clinically, the pelvic tumor aspiration biopsy operation is an important link for definite diagnosis and operation plan formulation, and has great significance for guiding subsequent treatment. For tumors with large volume and shallow position in the pelvis, the needle biopsy is simpler. However, most tumors in the pelvic region are deep, the anatomical site is complex (e.g., deep in acetabulum and ilium), the surrounding important blood vessels and nerves are adjacent, percutaneous precise needle biopsy is not easy, and precise preoperative planning and operation are often required.
For such biopsy procedures, it is currently often necessary to assist with imaging procedures. The biopsy under X-ray fluoroscopy cannot accurately locate a tumor in a pelvic region because it is difficult to provide three-dimensional spatial information of a lesion. The CT guided needle biopsy operation is mostly used for lesions with deep lesions and small range or lesions close to the vascular nerve bundle. Its disadvantages include the possibility to guide the puncture only in a limited scanning section, limiting the biopsy path; the radiation dose is larger; the operation is not flexible when the patient with fat physique and the region such as pelvis are punctured due to the limitation of the CT examination coil. MRI has the advantages of high soft tissue contrast ratio, multi-plane imaging, accurate positioning, no radiation and the like, but the clinical application of MRI is limited because of the lack of corresponding specific matching instruments for guiding bone biopsy. Other imaging technologies are still in the exploration stage, have high requirements on imaging equipment, and are difficult to popularize clinically.
