Abstract
A knob assembly and a circular stapler are provided. The knob assembly includes a knob driver, a knob body, a first cooperating component and a second cooperating component. In a blocking state, the first cooperating component is linked with the second cooperating component; while in an unblocking state, the first cooperating component is not fixedly linked with the second cooperating component. One of the first cooperating component and the second cooperating component is provided at the knob driver and the other one is provided at the knob body. When the knob driver is rotated, if a rotating resistance to the knob body reaches a preset resistance value, the knob assembly cannot transmit larger torque, therefore the knob assembly is in a failure mode, the position of the anvil assembly relative to the cartridge remains unchanged, and the tissues will not be excessively compressed.
