Description

Technical Field

[0001] The utility model relates to a puncture device, in particular to a puncture device with accurate positioning. Background Art

[0002] Tumor puncture is generally performed by inserting a needle into the tumor. The lump is usually seen under B-ultrasound. After positioning, the needle is inserted into the tumor under the guidance of B-ultrasound to perform a tissue biopsy. At the same time, the patient's tumor is located through CT scanning under a CT machine, and a biopsy is performed by puncturing the patient's tumor under the guidance of CT. Therefore, accurate positioning of the tumor puncture device is particularly important.
