Expandable heart hemostatic device

Abstract

The invention discloses an expandable heart hemostatic device, and belongs to the field of heart surgery. The expandable heart hemostatic device includes a hemostasis tube, a push rod arranged in thehemostasis tube and movably connected with the hemostasis tube, an unfolding groove formed in the bottom end of the hemostasis tube and coaxially arranged with the hemostasis tube, a push cylinder sleeving at the bottom end of the push rod and slidably connected to the push rod, a hemostatic umbrella arranged on the bottom side of the push rod and an umbrella frame arranged in the hemostatic umbrella and hinged with the hemostatic umbrella and the push cylinder separately; the diameter of the push cylinder is between the diameter of the hemostasis tube and the diameter of the unfolding groove,a first slide rail is arranged on the outer side of the push cylinder in the axis direction, a first sliding block corresponding to the first slide rail is arranged on the inner side of the unfoldinggroove, an umbrella folding rail perpendicular to the first slide rail is arranged on the outer side of the push cylinder in the circumferential direction, and arranged on the side of the bottom endof the first slide rail and communicates with the first slide rail. The hemostatic umbrella of the expandable heart hemostatic device can squeeze and fit the inner wall of a wound more tightly after the wound on the surface of a heart of a patient is stretched, so that the effect of blocking and hemostasis on the surface of the heart of the patient is improved.

Description

technical field [0001] The invention relates to the field of heart surgery, in particular to an expandable heart hemostatic device. Background technique [0002] A large category of heart diseases is manifested by various "defects" or "leaks" inside the heart, which includes not only ventricular septal defects, which account for 20% of all congenital heart diseases, but also a few Paravalvular leak after aortic or mitral prosthetic valve replacement is rare. The current relatively innovative method for treating such diseases is to puncture directly on the surface of the chest skin, and then further puncture the ventricle into the heart through image guidance to complete the closure treatment. But the biggest problem faced in this way is that after the internal blockage of the heart is completed and the catheter is withdrawn, a wound will be formed on the surface of the ventricle to stop bleeding. Since there is only a small wound with a diameter of a few millimeters on the...

[0003] At the same time, doctors often need to temporarily stop bleeding on the patient's heart during heart surgery. The existing hemostatic forceps are all simple to stop bleeding, and the hemostatic forceps cannot be fixed, resulting in poor hemostatic effect and unable to precisely control the hemostatic pressure. , and then can not normally perform cardiac surgery with temporary hemostasis
