Problems solved by technology

[0013] In addition, the aforementioned stereotaxic techniques used in neurosurgery are difficult to apply to operations on other parts of the human body. The main reason is that the position of soft tissues in other parts of the human body is not fixed relative to the surrounding bone tissue, making it difficult to achieve a consistent image space and patient space. Coordinate positioning
Therefore, there is no fixed guide and positioning device for interventional puncture in other parts of the human body to fix the direction of puncture. Usually, real-time CT images are used t

Abstract

The present invention discloses a percutaneous interventional puncture instrument through CT positioning, which is used in the guiding positioning of puncture needle in CT-guided percutaneous interventional surgery or other percutaneous interventional instrument. The device comprises a frame body and a cross bar fixed in the frame body. The cross bar is provided with an angular disk, which is provided with a position pointer. A hole is arranged in the position pointer. The fixing device for the puncture guiding device comprises a fixed block, a fixed bolt, a bolt sleeve and the fixing hole of the puncture guiding device arranged in the sleeve tube. The fixing device for the puncture guiding device is arranged in the hole of position pointer. The present invention is used in guiding positioning of needle in the targeted surgery or other percutaneous interventional instrument. Besides targeted interventional therapy for tumor, the present invention can be used in the treatment process of all CT guided percutaneous punctures requiring fixing needle or other percutaneous interventional instrument in a certain direction.

Description

technical field [0001] The invention is a CT positioning percutaneous interventional puncture instrument, which is used for guiding and positioning a puncture needle or other percutaneously inserted instruments in percutaneous interventional operations. Background technique [0002] A large number of clinical data show that: 70-80% of tumor patients are already in the advanced stage when they are diagnosed, and lose the chance of surgical resection. Traditional radiotherapy and chemotherapy are limited by dosage, so it is difficult to completely inactivate tumor cells, and the therapeutic effect is not satisfactory. In recent years, the development of new targeted ablation therapy technologies such as laser, freezing, radiofrequency, microwave and other physical ablation methods has changed the traditional concept of tumor treatment. Targeted therapy is to deliver a therapeutic probe to the tumor site through percutaneous puncture, and perform ablation therapy on the tumor ...
