Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an interventional delivery device for a occluder. Background Art

[0002] An occluder is a minimally invasive medical device used to treat cardiac structural abnormalities or defects, such as congenital heart diseases (atrial septal defect, ventricular septal defect) and acquired cardiac problems (left atrial appendage occlusion), etc. Its main principle is to deliver the occluder along the blood vessel into the cardiac defect site through an interventional operation, and after deployment, it is fixed at the lesion site to block abnormal blood flow or control thrombus movement.

[0003] After the occluder is delivered into the patient's body, when releasing the occluder, it is rather cumbersome and the occluder cannot be released quickly. For this reason, we propose an interventional delivery device for an occluder. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an interventional delivery device for an occluder, which overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above object, the present invention provides the following technical solution: An interventional delivery device for an occluder, including a cylinder body, an extension cylinder is fixedly installed at the bottom of the cylinder body, a movable column is movably arranged inside the extension cylinder, an annular groove and a vertical groove are formed in the inner wall of the extension cylinder corresponding to the movable column, a fixing ring is fixedly installed outside one end of the movable column close to the connecting block, and the fixing ring abuts against the side wall of the extension cylinder.

[0006] In a preferred example of the present invention, it can be further configured that: a rotating rod is arranged at one end of the movable column far from the extension cylinder, a movable plate is sleeved on the rotating rod, the movable plate abuts against the inner wall of the cylinder body, a movable rod is arranged at the top of the movable plate, a connecting disc is arranged at the top of the movable rod, and the rotating rod penetrates through the movable rod and extends to the top of the connecting disc and is sleeved with a knob.

[0007] In a preferred example of the present invention, it can be further configured that: the annular groove and the vertical groove are communicated with each other, convex blocks are uniformly arranged on the outer ring of the fixing ring, the convex blocks all extend into the annular groove, and the width of the convex block is the same as the width of the vertical groove.

[0008] In a preferred example of the present invention, it can be further configured that: a connecting block is arranged at the bottom end of the movable column, and a blocking block is connected through the connecting block, and a groove is formed in the bottom of the extension cylinder corresponding to the blocking block.

[0009] In a preferred example of the present invention, it can be further configured that: the side wall of the movable column abuts against the inner wall of the extension cylinder, and an installation ring is arranged at the top of the extension cylinder at the annular groove.

[0010] Advantages of the present invention: By providing a vertical groove and an annular groove, the present invention rotates the rotating rod to drive the fixed ring and the convex blocks provided outside the fixed ring to rotate in the annular groove. When rotating above the vertical groove, the movable rod is pulled to drive the movable column to retract, prompting the sealing block to separate from the connecting block, thereby releasing the sealing block, which is convenient and fast and reduces the operation time.
