The invention discloses a concentric, detachable and freely replaceable multifunctional targeted tumor scalpel used for treating various tumor treatments, which comprises an inner ring
pipe and an inner
pipe that are concentric. The mutual locations of the inner
pipe and the outer ring pipe can be axially adjusted, and the inner pipe can be fixed on a
handle through a connecting bar and can be detached from the outer ring pipe. The invention includes multifunctional applications of
cold therapy,
radio frequency ablation therapy,
microwave ablation therapy, endothermknife therapy,
laser ablation therapy, chemical therapy,
radiation therapy, immunization therapy,
gene therapy,
photodynamic therapy, electrochemotherapy and the like. Meanwhile, the inner pipe of the multifunctional targeted tumor scalpel can also be used as a diagnosis monitoring device, such as a temperature sensor, a
biopsy needle, a micro ultrasonic probe, an
