Description

Suture head for patent foramen ovale suture operation Technical Field The invention belongs to the technical field of patent foramen ovale suturing, and particularly relates to a suturing head for patent foramen ovale suturing operation. Background The patent foramen ovale is generally closed in 1 st year after birth, if the patent foramen ovale of the infant older than 3 years is still not closed, the patent foramen ovale is not closed, and 20% -25% of the adult foramen ovale is not fully closed. Patent foramen ovale is the most common congenital heart abnormality in adults today. Many researches in recent years show that close connection exists between patent foramen ovale and cerebral apoplexy patients with unknown causes, and aiming at etiology treatment, the patent foramen ovale of high-risk groups is closed, so that the incidence rate of patients is expected to be reduced. In addition, patent foramen ovale has also been found to be associated with the onset of decompression sickness, migraine, and the like, and closure of the foramen ovale may be beneficial to such patients. At present, a plugging operation is mostly adopted, namely a plugging instrument is operated, one plugging umbrella is respectively arranged at two sides of an oval foramen, the volume of the plugging umbrella is large, and because the structure in a heart is complex, and the plugging device is arranged in the heart, a plurality of patients are not easy to accept, and the occurrence risk of complications can be increased in the near term and the long term. Disclosure of Invention The present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a suture head for a patent foramen ovale suturing operation. The invention discloses a suturing head for a patent foramen ovale suturing operation, which is characterized by comprising an outer tube, a swinging rod and two needle tubes, wherein a mounting frame is arranged at the first end of the outer tube, the swinging rod is rotatably arranged on the mounting frame, a driving rod is arranged in the outer tube and used for enabling a person to pull one end far away from the swinging rod so as to rotate the swinging rod, two penetrating channels are symmetrically formed at the two ends of the swinging rod, suturing buckles are respectively arranged in the two penetrating channels, the two suturing buckles are connected through a connecting wire, the middle part of the connecting wire is connected with a pull wire, the two needle tubes are symmetrically arranged at two sides of the inner part of the outer tube, pushing rods are respectively arranged in tube cavities of the two needle tubes, insertion tips are respectively arranged at one ends of the two needle tubes far away from the insertion tips, the two pushing rods are connected with second pushing rods respectively extending from the two needle tubes, after the needle tubes penetrate through the penetrating channels, the two buckling buckles are respectively arranged in the two penetrating channels, and the side walls of the two needle tubes are respectively provided with a groove for being communicated with the side walls of the two needle tubes, which are arranged close to the driving rods, and the side walls of the two needle tubes are respectively provided with the rotating channels, and the side walls of the needle tubes are respectively provided with the rotating channels. The invention has the working principle that the driving rod, the first push rod, the second push rod and the stay wire are all provided with the operation ends extending from the second end of the outer tube, when the device is used, the outer tube is conveyed to the position of an atrium through the root of a thigh of a patient through the catheter insertion sheath, the swinging rod and the outer tube are positioned on the same straight line, then the device is positioned to the position of an oval hole by means of radiography observation, a worker pulls the driving rod to rotate and expand the swinging rod, so that two ends of the swinging rod are respectively aligned with diaphragms on two sides of the oval hole, then the worker pushes the first push rod, the two needle tubes extend from the outer tube and penetrate through the penetrating channel, then push the second push rod to push the two push rods until the two suture buckles are pushed out of the two needle tubes respectively, then the push rods and the needle tube are pulled back into the outer tube through the first push rod and the second push rod, the two suture buckles are positioned on the other side of the diaphragms, the two suture buckles can be pulled to be pulled together to drive the diaphragms on two sides of the oval hole, the connection parts of the connecting wire and the stay wire can be pre-tied, after the two buckles are pushed, the two suture buckles can be finally completed, and the minimally i
