Abstract

The invention discloses a suture-free aorta intubation device. The device comprises an outer sleeve, an inner sleeve, a main body and a surgical blade, wherein a cylindrical boss is arranged at the top in the outer sleeve, the inner sleeve is sleeved in a gap between the inner wall of the outer sleeve and the cylindrical boss, the main body is installed in the inner sleeve, the upper end of the main body abuts against the lower end of the cylindrical boss, and the surgical blade is fixedly mounted on the bottom surface of the cylindrical boss and is positioned in the main body; and two symmetrical strip-shaped holes are formed in the upper end of the outer wall of the outer sleeve, a handle is fixedly arranged at the upper end of the outer wall of the inner sleeve, the handle extends out of the strip-shaped holes and is in a U shape, the main body is composed of a nickel-titanium alloy support and a covering film attached to the surface of the nickel-titanium alloy support, and the main body is in a hollow cylinder shape with the upper portion and the lower portion open. According to the intubation device, the operation steps are simplified, the intubation device is operated by a single person, the main body can be mounted on an artery blood vessel only by three operation steps of stabbing, pulling and drawing, the operation is simple, the efficiency is high, and the safety isgood.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, in particular to a suture-free aortic catheterization device. Background technique [0002] The technique of vascular cannulation in surgical operations, especially the aortic cannulation operation in the establishment of extracorporeal circulation in heart and great vessel surgery, is widely used at home and abroad at present. Superficially suture the adventitia and media on the surface of the aorta. The suture can be covered with Dacron sheet or felt to prevent needle-hole bleeding. The end of the purse string suture is passed through the rubber or plastic sleeve for use, and then an incision is made in the purse bag, and then The arterial cannula is inserted into the incision, and finally the cannula on the suture is tightened and fixed to achieve hemostasis and fixation. [0003] This technology has the following problems in practical application: 1. Incorrect needle ins...
