Description

Ventricular therapeutic apparatus

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a ventricular therapy instrument.

Background

The ventricles (ventricles) are the two cavities below the interior of the heart, called the "left ventricle" on the left and the "right ventricle" on the right. The wall thickness of the ventricle and the muscles are developed. Wherein the left ventricle has thicker walls than the right ventricle, the muscles are more developed, and the root cause of heart failure is left ventricular dysfunction.

Patent number CN202122445183.6 discloses a diastolic assist device having an elastic spring structure; the elastic spring structure consists of an upper supporting spring wire, a lower supporting spring wire and a plurality of main spring wires connected between the upper supporting spring wire and the lower supporting spring wire, wherein the main spring wires protrude outwards relative to the upper supporting spring wire and the lower supporting spring wire, and the overall shape of the elastic spring structure in a natural state is similar to the shape of a left ventricle of a heart; the elastic spring structure contracts and stores elastic energy when being extruded by external force, and outwards rebounds to tend to be in a natural state when the external force disappears. The instrument made of the spring wire can be compressed to be implanted into a ventricle through a small incision of the ventricle wall, so that the heart wound during operation can be reduced, the damage to a patient is reduced, and the recovery period of the patient is shortened; the upper and lower support spring wires are outwards bent to store elastic energy when the main spring wire is pressed, and rebound along with the main spring wire when the main spring wire rebounds, so that the auxiliary strengthening effect can be achieved, and the main spring wire can be supported.

When the auxiliary heart diastole instrument is used, the structure is complex, the net structure of the auxiliary heart diastole instrument needs to be wholly implanted into a ventricle, and the auxiliary heart diastole instrument cannot be independently supported aiming at a problem part, so that the application provides a heart chamber treatment instrument for supporting a heart chamber.
