Rotary device for a vascular closure device and vascular closure device

Abstract

The utility model discloses a kind of rotating device and blood vessel closure for blood vessel closure, including handle, jaw sleeve and jaw assembly, jaw sleeve proximal end is inserted and connected in handle inner cavity, distal end is connected with jaw assembly, first printed circuit board assembly that jaw sleeve proximal end is equipped with can rotate synchronously with jaw assembly, at least two circles of guide ring are equipped thereon, second printed circuit board assembly is further equipped in handle inner cavity, and spring needle that cooperates with guide ring is equipped thereon, when jaw sleeve moves along axial direction, first printed circuit board assembly is moved relative to second printed circuit board assembly, make guide ring and spring needle contact or separate and realize the conduction or disconnection of circuit.By the above mode, the utility model can realize the 360 ° unrestricted rotation of jaw assembly and jaw sleeve, it is smooth and simple to operate, and stability is strong, effectively improve surgical efficiency;Ensure jaw and circuit to be disconnected when not excited, avoid burning normal tissue around blood vessel, guarantee surgical safety.
