[0064] Consistent with the first embodiment, the apical cuff 1 includes a sewing ring 11 and a flexible skirt 12 sleeved on the outer periphery of the sewing ring 11 for sewing to the apex of the heart. The back cover 21 of the blood pump body 1 is also provided with a sunken groove 22 and a sliding table 26 , and the gap between the sliding table 26 and the back cover 21 is a guide groove 25 . The rear cover 21 is provided with a locking piece sinking groove 27 inwardly, and the inner circle of the locking piece sinking groove 27 is a wedge-shaped guiding portion 271 .

[0065] The difference is that if Figure 11-13 As shown, the rear cover 21 of the blood pump body 2 is provided with two locking pieces 30 that can only move radially. The locking pieces 30 include an arc segment 36, and the two ends of the arc segment 36 are respectively It is a straight line segment 37 , and the straight line segment 37 movably extends into the guide groove 25 .

Abstract

The invention discloses a left ventricle auxiliary blood pump, which comprises a cardiac apex sleevelet and a blood pump body fixedly connected with the cardiac apex sleevelet, wherein the cardiac apex sleevelet comprises a suture ring and a flexible skirt edge which is sleeved at the periphery of the suture ring; the suture ring comprises a suture ring inner hole and a convex edge which is convexly arranged in the radial direction; the blood pump body comprises an inlet pipe; the inlet pipe is convexly arranged on a rear cover of the blood pump body; a peripheral ring slot is formed between the convex edge and the flexible skirt edge; a sliding sheet which can only move in the radial direction relative to the blood pump body is arranged on the rear cover of the blood pump body and is stretched into the peripheral ring slot in a movable way; the convex edge is positioned between the sliding sheet and the bottom surface of a settling tank; and the cardiac apex sleevelet and the blood pump body are relatively axially fixed. In the invention, the sliding sheet is used for fixing the cardiac apex sleevelet and the blood pump, so that the cardiac apex sleevelet can be more conveniently and reliably connected with the blood pump; simultaneously, the axial dimension of the inlet pipe of the blood pump is reduced, so that the implantation of the left ventricle auxiliary blood pump in a pleural cavity is facilitated without damages to a diaphragm, and the success rate of a surgery is greatly improved.

Description

technical field [0001] The invention relates to a left ventricular auxiliary blood pump, in particular to a connection structure between the left ventricular auxiliary pump and the heart, and belongs to the technical field of medical devices. Background technique [0002] The left ventricular auxiliary blood pump has its inlet connected to the apex of the heart, and its outlet connected to the arterial blood vessel. The connection between the heart and arteries is located in the chest cavity. There is a layer of diaphragm between the chest cavity and abdominal cavity. The diaphragm is also called the respiratory muscle. When the diaphragm descends, the volume of the chest cavity expands to help inhalation; when it relaxes, the diaphragm rises and returns to its original position, and the volume of the chest cavity decreases to help exhalation. Another function of the diaphragm is to separate the chest cavity from the abdominal cavity. The diaphragm itself is impermeable. ...
