Abstract

The invention relates to the technical field of medical instruments, and provides a conveying actuator and a conveying device. The conveying actuator comprises a clamp body, a joint and a steering knuckle, the clamp body is arranged at the front end of the actuator in an openable and closable mode through the joint, the steering knuckle is connected between the front end of a connecting rod and the rear end of the joint, and the steering knuckle is a universal connecting piece so as to adjust the pointing direction of the joint in all directions. 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 the 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...
