Patent Description:
Among many surgeries requiring precise operations, how to enable a medical instrument to be in a stable state relative to a living body has always been a medical difficulty. For example, a cardiac surgery is performed on a beating heart all the time since the heart is unable to suspend during the surgery, which greatly increases the surgical difficulty. <CIT> discloses a clinical puncture guidance positioning and fixing device, which includes an annular suction type suction cup, a supporting disk, a rotating disk and an arc-shaped arm.

In a specific operation, a doctor is difficult to achieve cardiac puncture and infusion of compounds after puncture since the heart is beating.

How to make the operation of the puncture needle, an endoscope and other operation instruments on the heart more stable has become a difficulty.

In view of this, it is necessary to provide a puncture adsorption mechanism for the above technical problems, which may enable an adsorption device to be stably connected to a viable tissue and facilitate a stable operation of a surgical instrument on a surface of the viable tissue.
