Embodiment 1

[0032] Please refer to Figure 1 to Figure 5 , this embodiment provides a left atrial appendage suturing device, the suturing device works under the real-time monitoring of intracardiac ultrasound, including a delivery sheath 1 and an operating handle 2, the operating handle 2 is connected with a delivery assembly, and the delivery assembly can Through the delivery sheath 1, the delivery assembly includes a plurality of strip-shaped delivery members 10, one end of each delivery member 10 is connected to an operating handle 2, so that the bending and bending of each delivery member 10 can be independently controlled by the operating handle 2. telescopic, the conveying member 10 is provided with a suture thread 20, and the end of the suture thread 20 is connected with a suture hook 21, and the suture hook 21 is located at the end of the corresponding conveying member 10; Auxiliary gap 3, the auxiliary gap 3 communicates with the mouth of the left atrial appendage and the outside...

Embodiment 2

[0042] Please refer to Example 1 on the basis of Figure 6 to Figure 10 , this embodiment provides a left atrial appendage suturing device, which is a further optimization of embodiment 1, the difference between this embodiment and embodiment 1 is only:

[0043] The beam mouth assembly includes a beam mouth ring 30 and a booster 31, the beam mouth ring 30 is hooped outside the conveying assembly, and the booster 31 is used to push the beam mouth ring 30 along the length direction of the conveying assembly move. By setting the beam mouth ring 30, the beam mouth ring 30 has elasticity and self-shrinkage performance, and it is pushed to the left atrial appendage by the booster 31, and it falls from the outer wall of the delivery member 10 to the outer wall of the suture wire 20, so that the self-shrinkage will The suture thread 20 is tightened so as to avoid the steps of pulling the string and pulling the string in Embodiment 1.

[0044] It should be noted that the beam mouth r...

Abstract

The invention discloses a left auricle suturing device for transfemoral vein approach interventional operation and application thereof, the left auricle suturing device is used for suturing a left auricle opening and preventing cerebral infarction caused by atrial fibrillation, and belongs to the technical field of minimally invasive intervention.The left auricle suturing device comprises a conveying sheath and an operating handle, the operating handle is connected with a conveying assembly, and the conveying sheath penetrates through the atrial septum through a femoral vein approach to reach the left auricle opening; the conveying assembly reaches the mouth of the left auricle through the conveying sheath and comprises a strip-shaped conveying piece, one end of the strip-shaped conveying piece is connected with the operating handle so that the conveying piece can be independently controlled to bend and stretch out and draw back through the operating handle, a suture wire is arranged in the conveying piece, the end of the suture wire is connected with a suture hook, and the suture hook is located at the end of the corresponding conveying piece. The left auricle mouth suture is completed without a thoracotomy, and no implant is left in the body after the suture material is degraded; the operation is carried out under real-time monitoring of ultrasound in the heart cavity, accurate operation of the operation can be achieved, and complications are reduced.

Description

technical field [0001] The application belongs to the technical field of interventional minimally invasive suturing, and in particular relates to a left atrial appendage suturing device and application for interventional surgery via femoral vein approach. Background technique [0002] At present, the complication of cerebral infarction caused by atrial fibrillation has been widely concerned and paid attention to by clinicians. The cause of this complication is left atrial appendage thrombus. The left atrial appendage is a long, narrow, curved blind-end structure that extends forward and downward along the anterior wall of the left atrium (LA). Due to its blind-end structure, when atrial fibrillation occurs, the atrium loses its function and beats irregularly. The blood tends to form a vortex at the mouth of the left atrial appendage, resulting in slow blood flow in the left atrial appendage and the formation of thrombus. The thrombus falls off and leads to complications such...
