Abstract

Relates to the technical field of medical instruments, and provides a conveying actuator and a conveying device. The conveying actuator comprises a first arm body, a second arm body and joints, and the first arm body is hinged to the second arm body through the joints, so that the first arm body and the second arm body are close to each other to be in a clamping state or far away from each other to be in an opening state;the first arm body comprises a first positioning groove located in the inner side edge, and the second arm body comprises a second positioning groove located in the inner side edge; the first positioning groove and the second positioning groove are arranged in an aligned manner, and the first positioning groove and the second positioning groove are respectively used for accommodating one side of an object to be placed; the first arm body and the second arm body are further fixed to the corresponding side edges of the object to be placed through fixing pieces respectively. In this way, smoothness in the feeding process can be guaranteed to the maximum extent through the small front end size, operation and control convenience is guaranteed through matched assembly of positioning grooves and the clamping arms, the operation difficulty is lowered, and finally the overall risk of the operation is lowered.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a delivery actuator and a delivery device. Background technique [0002] Atrial fibrillation is one of the most common clinical arrhythmias. The consequences of stroke caused by atrial fibrillation are very serious, and the mortality rate and disability rate can reach 70%. For patients with valvular atrial fibrillation, 57% of atrial thrombi originated from the left atrial appendage, and for patients with non-valvular atrial fibrillation, 90% of left atrial thrombi originated from the left atrial appendage. Even after restoration of sinus rhythm, left atrial appendage contraction stuns, there is still the possibility of re-thrombosis. [0003] At present, there are three main methods to prevent ischemic stroke in AF clinically. One method is to take anticoagulant drugs, such as warfarin, but the use of warfarin has a certain risk of bleeding, and requires frequent m...
