Loading tool for heart valve

Abstract

The invention discloses a loading tool for a heart valve, which comprises a fixed seat, a connecting piece, a buckling piece and a protective tube, the fixed seat and the protective tube are connected at two ends of the connecting piece, and the buckling piece is sleeved at the joint of the connecting piece and the protective tube; a conveyor inlet and outlet is formed in the fixing base, and a sealing piece allowing an external conveyor to enter and exit is arranged at the conveyor inlet and outlet. According to the loading tool, the protection tube is fixed in an embedded mode, namely in a buckling piece mode, glue bonding is not needed, assembling is easy and convenient, meanwhile, the protection tube can be easily removed from the loading tool, the operation time is shortened, and the use experience of a user is enhanced; and popularization and application of the loading tool for the heart valve in the technical field of medical instruments are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a loading tool for heart valves. Background technique [0002] In recent years, there has been increasing interest in prosthetic heart valves that are delivered through blood vessels to the heart's implant site. Compared with conventional heart valve surgery, access to the heart through a sternotomy or other thoracic incision is not required. Complexity, reducing the invasiveness to the patient, and the postoperative recovery time of the patient is also shortened. [0003] For example, to deliver an aortic valve, it can be implanted from the patient's groin region into the femoral artery, through the aortic fork, up the aorta, and finally to the aortic valve in the heart. Usually, before reaching the implantation site for expansion, the artificial valve is crimped to a smaller size by a pre-clamping device, in order to reduce its radial width and not affect its passi...

AI Technical Summary

Problems solved by technology

For example, some loading tools are complex in design and have many parts, which makes their use significantly more difficult and increases the risk of surgery, and the larger size is only suitable for the products that match them, and the versatility of the products is not good.

There are also other loading tools on the market. Although the necessary parts are fixed with glue, it is more convenient during the operation. However, in order to reduce the damage of the loading tool to the blood vessels, the protective tube is generally made of a material with relatively high smoothness. This kind of material is usually glued. It is difficult to bond firmly. Therefore, it has high requirements for process methods and raw materials. In addition, because the product is designed as one, the difficulty of product recycling is greatly increased, which does not conform to the current environmental protection concept.
