Embodiment 1

[0041] Please refer to figure 1 , which is a schematic structural diagram of a pericardial endoscope according to an embodiment of the present invention. Such as figure 1 As shown, the pericardial endoscope 1 includes: a catheter 10; an endoscope assembly 11 connected to one end of the catheter 10 and an expansion balloon 12, and the expansion balloon 12 is located outside the endoscope assembly 11; A control handle 13 connected to the other end of the catheter 10 , the control handle 13 includes a filling device 131 capable of filling the inflation balloon 12 .

[0042] In the embodiment of the present application, the catheter 10 includes a first catheter 101 and a second catheter 102 connected to the first catheter 101, wherein the first catheter 101 is a deflectable structure, and the endoscope assembly 11 And the expansion balloon 12 is connected with the first catheter 101 . Here, the first catheter 101 is designed as a deflectable structure, which facilitates the end...

Embodiment 2

[0050] Please refer to image 3 , which is a structural schematic diagram of a lasso device according to an embodiment of the present invention. Such as image 3 As shown, in the embodiment of the present application, the noose device 2 includes: a noose structure 20; a noose catheter 21 connected to the noose structure 20; and an operating handle 22 connected to the noose catheter 21 , the operating handle 22 controls the tension of the noose structure 20 and controls the noose structure 20 to disengage from the noose catheter 21; wherein, the noose structure 20 adopts a cable tie structure.

[0051] Specifically, please refer to Figure 4a with Figure 4b ,in, Figure 4a is a schematic diagram of the cable tie structure of the embodiment of the present invention; Figure 4b It is another schematic diagram of the cable tie structure of the embodiment of the present invention. Here, two common cable tie configurations are shown. Specifically, such as Figure 4a As show...

Embodiment 3

[0057] The third embodiment provides a system for closing the left atrial appendage of the heart. The system for closing the left atrial appendage of the heart includes a pericardial endoscope; a lasso device; and a clamping device; wherein, the pericardial endoscope is used to confirm the position of the left atrial appendage , the clamping device is used to fix the left atrial appendage, and the lasso device is used to block the left atrial appendage. Wherein, the pericardial endoscope may refer to the structure in the first embodiment, and the lasso device may refer to the structure in the second embodiment, which will not be repeated in this embodiment.

Abstract

The invention provides a pericardium endoscope, a lasso device and a heart left aurcle closing system which are simple in instrumental design, low in cost, and low in operating requirement. Particularly, when left aurcle closing operating is carried out, the pericardium endoscope enters a pericardial cavity through pericardiopuncture. After an expanding saccule is inflated and expanded, observing is carried out, and the position of the left aurcle is confirmed. A clamping device also enters the pericardial cavity through the pericardiopuncture. The pericardium endoscope is utilized to obtain an observing image, clamping is carried out on the left aurcle, and the left aurcle is fixed. After clamping is fixed, the lasso structure is sleeved with the clamping device, enters the pericardial cavity and is sleeved with the left aurcle. An operating handle controls the lasso structure to be fastened and to be separated from a lasso guiding pipe, and closing/blocking operating of the left aurcle can be completed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pericardial endoscope, a lasso device and a heart left atrial appendage closing system. Background technique [0002] There are two main methods for the treatment of atrial fibrillation. One is to restore sinus rhythm, such as catheter ablation, and the other is to control the heart rate combined with the prevention of thrombosis. Among them, the embolism caused by atrial fibrillation mainly originates from the left atrial appendage; even if the sinus rhythm is restored after treatment, the left atrial appendage is stunned, and thrombus may still form again. Therefore, occlusion of the left atrial appendage can greatly reduce the risk of stroke. [0003] At present, the left atrial appendage is mainly blocked by intracardiac intervention, such as PLAATO system, Amplatzer system and Watchman system. These LAA occlusion devices all enter the right atrium through the...
