The invention aims to solve the problem of difficulty in accurate positioning and guiding during puncture in the prior art, and discloses a multi-point puncture positioning
mechanism based on
liver cancer radio frequency ablation. The mechanism comprises a guide rod, a protective layer, a supporting plate, an anti-slip layer, a pull ring, a baffle plate, a first spiral spring, a sliding rod, a clamp plate, a guide plate, a connecting block, a sliding block, a second spiral spring, a guide frame, a clamping plate, a positioning plate, a base, universal wheels, a supporting rod, a connecting rod, a holding ring, a
lantern ring, a first fastening screw, a second fastening screw, an inner ring, an outer ring, a positioning rod, a mounting plate, a first
laser lamp, a second
laser lamp, a
whiteboard, a fixing plate and a guide groove. The multi-point puncture positioning mechanism reasonably utilizes the cooperation of the first spiral spring and the second spiral spring to realize the pulling of the clamp plate on the
skin of the obese patient, so that the loose proud
flesh is supported tightly, and then accurate puncture is easier to be carried out during the puncture is carried out;and by combining the positioning and the guiding of the first
laser lamp and the second laser lamp, it is convenient for the mechanism to carry out accurate puncture on the patient, and the mechanismmeets the social requirements.
