Abstract

The invention relates to a clamping device and a suturing device. The clamping device of the present invention includes a sheath assembly and a clamping assembly. The sheath assembly includes an inner tube and an outer tube. The outer tube is sheathed on the outside of the inner tube and can move axially relative to the inner tube. The clamping assembly and the inner tube The distal end is connected or the clamping assembly is arranged at a position close to the distal end of the inner tube, and the clamping assembly includes a first clamping unit and a second clamping unit oppositely arranged, the first clamping unit and the second clamping unit There is an included angle between the clamping units, and the size of the included angle can be adjusted. According to the suturing device of the present invention, the clamping process of the septum secondary or the septum primary can be effectively completed, and subsequent operations are facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a clamping 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 a...
