Three-dimensional rapid capture device and manufacturing method thereof

Abstract

The invention relates to a rapid capture device of a three-dimensional structure. Compared with an existing two-dimensional plane loop capture device, the three-dimensional rapid capture device has the advantages that due to the fact that the three-dimensional structural design is adopted, the space where capture can be conducted is greatly expanded and a leap from the two-dimensional plane to the three-dimensional structure is achieved. The three-dimensional rapid capture device comprises a handle, a capture rod and a capture sleeve. One end of the capture rod is connected with the handle and the other end of the capture rod is connected with the capture sleeve. The capture sleeve comprises at least three spiral capture wires, wherein the two ends of each capture wire are connected with the two ends of another capture wire respectively. When the capture sleeve is used, the capture wires face one another and are expanded in a spiral mode, so that a three-dimensional network space is formed. The three-dimensional rapid capture device is applied to a congenital heart disease cardiac transcatheter closure operation and other transcatheter interventional therapy (such as an arterial aneurysm operation) and is used for rapidly capturing guidewires to establish a conveying track.

Description

[0001] Technical field [0002] The present invention involves the field of medical device, especially in a three -dimensional fast arrest in congenital heart disease and other managing intervention treatment (such as aneurysms)method. [0003] Background technique [0004] Interventional therapy is currently widely used in the medical treatment of the human body. Because of its fast and practical, it is very popular with doctors.If the congenital heart disease is required to be involved in the sealing surgery, a special arrest device needs to establish a guide silk track for the conveyor blocking device in the human body.The capture device is used to treat the septal defect in the treatment of the skin, and the capture of the capture in the surgery of the arterial catheter to establish a dynamic vein orbit.Take a look figure 2 The left side of the middle, the general capture contains the PTFE sleeve, nickel titanium silk, and the arrest cover. figure 2 It can be seen that the ar...

Problems solved by technology

However, many of the catchers currently used are imported products, and the high price makes it difficult for patients to bear, which makes it difficult for many hospitals to use them once. Instead, they are sterilized and then used again. Strict sterilization takes a long time. Time, very complicated procedures, theoretically feasible, but in reality it is difficult to do, which brings the possibility of cross-infection of patients
