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

Embodiment 1

[0047] Embodiment 1: a kind of occluder for paravalvular leak, such as Figure 2-6 As shown, it includes a front-end umbrella tray, a rear-end umbrella tray and a support body. The support body includes a support sleeve 202, a support inner rod 203, and two movable end bodies 201; the support inner rod 203 is rotationally connected with the support sleeve 202, and supports The two ends of the inner rod 203 respectively protrude from the two ends of the support sleeve 202; the movable end body 201 is provided with a rotation adjustment groove 206, a placement groove, and an adjustment through hole 214 which are connected in turn and run through the two ends of the movable end body 201, and the adjustment through An annular groove 215 is arranged on the inner wall ring of the hole 214, and at least one arc groove 211 is arranged in the annular groove 215; The limit baffle plate 213 that is movably connected; the support inner rod 203 is threadedly matched with the rotating sleev...

Embodiment 2

[0057] Embodiment 2: a kind of interface adjusting device, such as Figure 5 and Figure 7 As shown, the device can be used in conjunction with the occluder described in the embodiment, including a rotating adjustment body 301 and a lifting adjustment body 305; one end of the rotating adjustment body 301 is provided with a connecting sleeve 302, and the other side is provided with a socket for accommodating lifting The receiving groove 303 of the adjusting body 305 is movably connected with the control rod 307 connected with the lifting adjusting body 305 in the connecting sleeve 302 . When the polygonal rotation adjustment body 301 is used to control the rotation of the above-mentioned polygonal rotation adjustment groove 206, the lifting adjustment body 305 is placed in the accommodation groove 303, and under the restriction of the accommodation groove 303, the elevation adjustment body 305 is synchronized with the rotation adjustment body 301 Rotation; when the rotation ad...

Abstract

The invention discloses an occluder and an interface adjustment device for paravalvular leakage, and relates to the technical field of medical devices. The key points of the technical scheme are: a support body includes a support sleeve, a support inner rod and a movable end body; the support inner rod It is rotatably connected with the support sleeve; the movable end body is provided with a rotation adjustment groove, a placement groove, and an adjustment through hole, and the inner wall ring of the adjustment through hole is provided with an annular groove, and an arc groove is arranged in the annular groove; the rotation in the annular groove The rotating sleeve is connected, and the outer wall of the rotating sleeve is provided with a limit baffle; the supporting inner rod is threadedly matched with the rotating sleeve, and the end of the supporting inner rod is connected with an adjusting body, and the adjusting main body is provided with a lifting adjustment slot; the front umbrella plate, the rear umbrella The disks each include a first umbrella disk and a second umbrella disk; the first umbrella disk is fixedly connected to the supporting sleeve, and the second umbrella disk is fixedly connected to the corresponding movable end body. The present invention can effectively reduce the maximum length of the front-end umbrella disk and the rear-end umbrella disk, so that the occluder for paravalvular leakage can be transported conveniently and efficiently in the 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...
