Abstract

The limiting device comprises a sheath tube assembly and a limiting support, the sheath tube assembly comprises an inner tube and an outer tube, the outer tube is arranged outside the inner tube in a sleeving mode and can axially move relative to the inner tube, the near end of the limiting support is connected with the inner tube, and a first part of the far end of the limiting support is turned outwards or bent outwards towards the near end of the limiting support in a natural state; the second part is expanded outwards in the radial direction, and the limiting bracket is accommodated in an accommodating space formed by the inner pipe and the outer pipe in an elastic deformation manner under the extrusion of the outer pipe. According to the limiting device, the primary septum and the secondary septum can be effectively prevented from shifting in the puncturing or suturing process, so that the accuracy after puncturing or suturing is effectively guaranteed, and the success rate of rehabilitation of a patient is increased. The invention further provides a suturing device.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a limiting device and a suturing device. Background technique [0002] The foramen ovale is a physiological channel in the embryonic stage of the atrial septum of the heart. The fetus has no pulmonary circulation, and oxygenated blood from the umbilical cord flows from the fetal right atrium through the foramen ovale to the left atrium. After birth, with the establishment of pulmonary circulation, the left atrial pressure increases, the secondary septum and primary septum approach each other, adhere and fuse, and gradually form a permanent atrial septum. However, there are still some people who have not merged, forming a patent foramen ovale (PFO). [0003] In most cases, the pressure of the left atrium of the human heart is greater than that of the right atrium, and the PFO is in a closed state. In certain circumstances, the PFO channel can be pushed apart...
