Embodiment Construction

[0020] The titanium-nickel memory alloy blood vessel stapler of the present invention comprises a helical titanium-nickel memory alloy wire 3 with different diameters and two semicircular suture needles 1 arranged at both ends of the titanium-nickel memory alloy wire 3 at 27-33°C. , the two ends of the nickel memory alloy wire 3 are respectively connected with the suture 2 and two semicircular suture needles 1 . The titanium-nickel memory alloy wire 3 and the two sutures 2 are of an integrated structure, and the two semicircular suture needles 1 and the sutures 2 are connected by welding. The suture 2 is generally a straight line, and the included angle between the suture 2 and the axial direction of the helical titanium-nickel memory alloy wire 3 ranges from 60° to 90°.

[0021] The blood vessel stapler of the present invention can be pulled apart at normal temperature, and returns to a "spiral shape" when it is close to the temperature of the human body, and is in a superela...

Abstract

The invention relates to a blood vessel anastomat made of nickel-titanium memory alloy, comprising a nickel-titanium memory alloy wire with a spiral memory shape at the temperature of 27-33 DEG C, two semicircle sewing needles arranged at the two ends of the nickel-titanium memory alloy wire, and two seams connecting the nickel-titanium memory alloy wire and the two seams of the two semicircle sewing needles. According to the blood vessel anastomat made of the nickel-titanium memory alloy, the technical problems of the conventional blood vessel seaming method that the seaming speed is low, the blood vessel convolution is bad, the blood flow is poor, and hemadostenosis is caused by hyperblastosis of anastomotic are solved. The blood vessel anastomat made of the nickel-titanium memory alloy has the advantages of convenience for operation, short time for seaming, and substantial improvement on the blood vessel seaming speed.

Description

technical field [0001] The invention relates to a human blood vessel stapler, in particular to a human blood vessel stapler made of titanium-nickel memory alloy material. Background technique [0002] Vascular anastomosis is a form of surgery in clinical surgery, which is mainly performed for trauma or artificially caused vascular rupture. At present, the conventional suturing method in clinical practice is very slow in suturing, the blood vessels are not well aligned, the blood flow is not smooth, and the blood vessels are narrowed due to tissue hyperplasia at the anastomosis. Especially the anastomosis of tiny blood vessels clinically applied in microsurgery is more difficult. Contents of the invention [0003] The object of the present invention is to provide a titanium-nickel memory alloy blood vessel stapler made of titanium-nickel shape memory alloy material, which solves the problems of slow suturing speed, poor blood vessel alignment, poor blood flow, and tissue h...
