Plate track and the needle holder of real-time adjustment angle replace changeless template needle track in the prior art, can be at any time according in art
Actual conditions change adjustment puncture needle angle, and can with spininess, multi-angle, in real time it is non-co-planar.
(2) device, which is applied single-handedly to puncture relative to doctor, can reduce operating difficulty, operating time, CT when reducing operation
Scanning validation number reduces suffered roentgen dose X in patient's art simultaneously, reduces young doctors minimally-invasive treatment learning cycle, opens rapidly
Exhibition industry is engaged in.
(3) the guiding puncture equipment that device application has application to clinic at present relatively has registration, repeats profit
It is low with, cost, flexibly, more pin punctures and the angles and positions that puncture needle be adjusted flexibly can be changed according to lesions position, can
With according to the non-co-planar puncture of the real-time spininess of actual conditions in treatment plan and art.
