Method for conducting puncture navigation in CT interventional therapy and puncture navigation device

Abstract

The invention relates to a method for conducting puncture navigation in a CT interventional therapy and a puncture navigation device. The puncture navigation device comprises a microprocessor, a position sensor, a communication module and a direction indicator, and the puncture navigation device is connected with a CT scanning system; the puncture navigation method comprises the steps that the CT scanning system plans a preset needling insertion angle on a CT image and transmits the preset needling insertion angle to the puncture navigation device; the puncture navigation device transmits space angle information of a puncture needle to the CT scanning system and virtually displays the space angel information on the CT image; a space angle of the puncture needle is adjusted by observing the CT image or according to a hint of the direction indicator to enable the space angle of the puncture needle to be overlapped with the preset needling insertion angle; needle insertion is started, and when the needle head of the puncture needle reaches a puncture target point, the CT scanning system conducts scanning again to confirm whether the puncture needle is in position or not. According to the method for conducting puncture navigation in the CT interventional therapy and the puncture navigation device, the puncture accuracy is improved, the puncture complexity is reduced, the number of insertion of the needle is decreased, and pain borne by a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of CT interventional therapy, in particular to a method for puncture navigation in CT interventional therapy and a puncture navigation device. Background technique [0002] At present, in interventional therapy and detection (biopsy), the CT system mainly plays the role of assisting positioning based on CT images and confirming the condition of the lesion and surrounding tissues after puncture. In practice, after confirming human organ lesions through CT scan, the optimal needle insertion point, needle insertion angle and needle insertion depth can be planned according to the CT image. In the actual operation of the puncture, whether the angle of the needle insertion is appropriate depends mainly on the doctor's personal experience and Subjective judgment, the accuracy is poor, and it is rare to achieve the desired effect after one needle insertion, and it often needs repeated attempts and repeated confirmat...

Problems solved by technology

In practice, after confirming human organ lesions through CT scan, the optimal needle insertion point, needle insertion angle and needle insertion depth can be planned according to the CT image. In the actual operation of the puncture, whether the angle of the needle insertion is appropriate depends mainly on the doctor's personal experience and Subjective judgment, poor accuracy, seldom can achieve the desired effect after one needle insertion, and often need repeated attempts and confirmations to get close to the puncture target position

Therefore, multiple CT irradiations and even multiple punctures are required to cause additional damage
