Embodiment 1

[0046] figure 1 It is a schematic diagram showing the first perspective stereoscopic structure of the conveying device in Embodiment 1 of the present invention, figure 2 It is a schematic diagram showing the stereoscopic structure of the second viewing angle of the conveying device in Embodiment 1 of the present invention, and image 3 It is a schematic diagram showing the structure of the conveying actuator in Embodiment 1 of the present invention; Embodiment 1 of the present application provides a follow-up conveying actuator, which mainly includes a first tong arm 1, a second tong arm 2, a connecting rod 3, and a joint 4 and two connecting arms 5. The first pliers arm 1 and the second pliers arm 2 forming the jaws are hinged at the front end of the joint 4 in an openable and closable manner, and the connecting rod 3 can be hinged at the root of the jaws to the first jaw. Between the arm 1 and the second pliers arm 2, the connecting rod 3 can be used to controllably open ...

Embodiment 2

[0059] Figure 6 It is a schematic diagram showing the three-dimensional structure of the conveying device in Embodiment 2 of the present invention, Figure 7 It is a structural schematic diagram showing the first viewing angle of the coupling of the conveying device in Embodiment 2 of the present invention, and Figure 8It is a schematic structural diagram showing the second viewing angle of the shaft coupling of the conveying device in the second embodiment of the present invention.

[0060] As shown in the figure, the main difference between the second embodiment of the present application and the first embodiment is that in this embodiment, an omnidirectional joint is used to carry out the free orientation of the actuator, wherein the joint 4 includes a pivot seat 43, a coupling 42 and the interface 41 connected with the connecting rod 6, the pivot seat 43 includes a first pivot seat 433 and a second pivot seat 435, and a connecting shaft can be fixed through the first sh...

Embodiment 3

[0065] Figure 9 It is a schematic structural diagram showing the delivery actuator in Embodiment 3 of the present invention, and Figure 10 It is a schematic structural diagram showing the delivery device in Embodiment 3 of the present invention. As shown in the figure, the main difference between Embodiment 2 of the present application and Embodiment 1 and 2 is that in this embodiment, a set of disc spring joints 61 (or called ball hinge joints) arranged on the connecting rod 6 are used to Carry out the free orientation of actuator, simultaneously by the shape of controller 8 given in this embodiment, can understand a kind of controller shape that can be applied in the actuator of other embodiments of the present application, wherein controller 8 can be a gun grip Bundle. A wrench 81 can be hinged at the front end, and the wrench 81 can be used to connect with the connecting rod 3 through a control line, so as to control the opening or closing of the actuator.

Abstract

It relates to the technical field of medical devices. This application provides a follow-up delivery actuator and an auricle clip delivery device. The follow-up delivery actuator includes a first forceps arm, a second forceps arm, a connecting rod, a joint, and two connecting arms; The first pliers arm and the second pliers arm are hinged at the front end of the joint in an openable and closable manner, and the connecting rod is hinged between the first pliers arm and the second pliers arm, and the first pliers arm and the second pliers arm are opened or closed by the connecting rod. Arm; the two connecting arms are respectively rotatably connected to the front ends of the first tong arm and the second tong arm, and the two connecting arms are respectively connected to both sides of the object to be inserted through a fixing piece. To solve the problem that the delivery device in the prior art is bulky and inconvenient to operate, there is no need to configure a complicated connecting rod holding structure to keep the arm body connected with the object to be placed in parallel, and the follow-up connecting arm is a follow-up It is dynamically connected to the clamp arm, which can freely adapt to the angle and deformation tendency of the clamp arm of the object to be placed, and is better adapted to the object to be inserted.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a follow-up delivery actuator and an auricle clip 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,...
