Compression device for artificial valve replacement device

Abstract

The invention discloses a compression device for an artificial valve replacement device. The compression device comprises at least two clamp unit blocks; and the clamp unit blocks are inserted in a staggered way and are connected with each other in sequence through a comb structure and enclose a scaling channel. The compression device further comprises a guide structure for leading all the clamp unit blocks to fold towards the center of the scaling channel. According to the invention, when the artificial valve replacement device is placed in the scaling channel, the inner wall of the scaling channel props against the peripheral wall of the artificial valve replacement device; and when the clamp unit blocks are folded towards the center of the scaling channel under the action of outside force, the inner wall of the scaling channel simultaneously applies the force directing to the central direction of the scaling channel onto the peripheral wall of the artificial valve replacement device. The compression device has the beneficial effects that the manufacturing cost is low, the cleaning is convenient due to simple structure, and the requirements for operation sanitation during use can be completely satisfied, therefore, the production and maintenance costs are reduced, and the expense shifted to consumers is reduced.

Description

technical field [0001] The invention relates to a compression device, in particular to a compression device of an artificial valve replacement device. Background technique [0002] When the patient's own heart valve is mutated due to congenital or acquired diseases, causing the valve to fail to open and close normally, it will affect healthy life and even life. The variation of the heart valve can be divided into insufficiency and insufficiency, both of which can cause increased heart load. Whether the heart can still work normally under this load is the main basis for deciding whether the human heart valve should be replaced. And when the patient needs to change the valve, the existing method is to adopt surgical operation to change the valve. The doctor will open the chest for the patient and stop the heart, and connect it to the extracorporeal cardiopulmonary circulation system. Then open the patient's heart to remove the diseased heart valve, then suture the artificial ...

Problems solved by technology

The device has a complex structure and high manufacturing cost. Because of its complex structure, it is difficult to clean and sterilize, so it is required to be used for one-time use, which undoubtedly causes a great burden to the patient; As a result, it is impossible to use a simple cooling method (such as a flat plate with an ice-water mixture) to perform martensitic phase transformation treatment on the nickel-titanium memory alloy stent, so that the stent becomes soft at low temperature and then compressed, such as letting the stent in austenite Compressed in contrast, it will generate several times the radial support force, which will make loading difficult and easily cause sheath damage
