Problems solved by technology

Although the occluder for the treatment of paravalvular leakage has been improved from the design direction of reducing the width and extending the length, which effectively solves the incidence of complications after heart valve replacement, but its too long structure is transported during interventional treatment through a catheter. Difficulty, prolonged operation time

Abstract

The invention discloses a plugging device for perivalvular leakage and a connector adjusting device, and relates to the technical field of medical instruments. According to the technical scheme, the plugging device is characterized in that a supporting body comprises a supporting sleeve, a supporting inner rod and a movable end body; the supporting inner rod is rotationally connected with the supporting sleeve; a rotary adjusting groove, a containing groove and an adjusting through hole are formed in the movable end body, an annular groove is annularly formed in the inner wall of the adjusting through hole, and an arc-shaped groove is formed in the annular groove; a rotary sleeve is rotationally connected into the annular groove, and a limiting baffle is arranged on the outer wall of the rotary sleeve; the supporting inner rod is in threaded fit with the rotary sleeve, the end of the supporting inner rod is connected with an adjusting body, and the adjusting body is provided with a lifting adjusting groove; a front end umbrella disc and a rear end umbrella disc each comprise a first umbrella disc and a second umbrella disc; and the first umbrella discs are fixedly connected with the supporting sleeve, and the second umbrella discs are fixedly connected with the corresponding movable end body. The maximum length of the front end umbrella disc and the maximum length of the rear end umbrella disc can be effectively reduced, so that the plugging device for perivalvular leakage is convenient and efficient to convey in a catheter.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, to an occluder and an interface adjustment device for paravalvular leakage. Background technique [0002] At present, the traditional methods of using occluder to treat ventricular septal defect (VSD), atrial septal defect (ASD) and patent ductus arteriosus (PDA) include surgical operation and medical intervention. On the one hand, traditional surgical operations require central or lateral thoracotomy, and require extracorporeal circulation. The incision is long (15-20cm), the trauma is large, the operation time is long, and it takes 2-3 hours at the fastest, and the postoperative pain is severe. , Slow recovery, long hospital stay, obvious skin scars, affecting appearance. On the other hand, medical intervention mainly uses a small catheter to make an 8-10 mm incision through the root of the thigh, and the occluder is accurately placed in the defect or defect in t...
