Patent foramen ovale suture device and use method thereof

Abstract

The invention relates to a patent foramen ovale suture device and a use method thereof. The patent foramen ovale suture device comprises an outer pipe and an inner pipe, wherein the inner pipe can slide in the outer pipe, a suture line penetrating groove is formed at a center of the inner pipe, two traction needle grooves are symmetrically formed in the inner pipe, the top ends of the traction needle grooves are arc-shaped, guiding blocks are arranged on an end portion of the inner pipe, the edges of the guiding blocks are arc-shaped, and are aligned with the traction needle grooves, elastic traction needles are arranged in the traction needle grooves, the elastic traction needles can slide along the traction needle grooves and the edges of the guiding blocks, clamping holes correspondingto the elastic traction needles are formed in portions, corresponding to the guiding blocks, on an end surface of the outer pipe, line hooks are arranged in the clamping holes, and suture lines are arranged on the elastic traction needles. The patent foramen ovale suture device is used for minimally-invasive surgery suture when a foramen ovale in a heart is patent, and the situation that in a cardiography state of the heart, suture line positions are vague, so that operation is difficult can be avoided, so that the surgery efficiency is effectively improved.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to a patent foramen ovale suturing device and a method for using the same. Background technique: [0002] The foramen ovale is a small hole between the left and right atrial septum in the heart. It usually closes in the first year after birth. If the foramen ovale is still not closed in children older than 3 years old, it is called a patent foramen ovale. In adults, 20%~ 25% of the foramen ovale was not completely closed. Patent foramen ovale is the most common congenital heart abnormality in adults. The existing treatment methods generally use closure surgery to place a large metal occluder in the body, but since the occluder is mostly made of metal Preparation, long-term implantation of the heart may cause the occluder to gradually corrode and release toxic substances due to the corrosion of blood and the friction caused by the beating of the heart, which may increase th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a patent foramen ovale suturing device and its use method, which are used for the suturing operation of patent foramen ovale, and solve the difficulty in hooking the metal suture with the traction needle in the existing suture operation, resulting in difficult operation. And metal sutures are easy to send out alarms in security check occasions, which is not easy to be accepted by patients
