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
The present invention relates to a kind of human vas anastomat, particularly a kind of human vas anastomat with the ti-ni shape memory alloy material.
Background technology
Vascular anastomosis is a kind of operation form in the surgical clinical, is primarily aimed at wound or people and is the modus operandi of a kind of vascular anastomosis that the rupture of blood vessel that causes exercises.The speed that present conventional sewing method is clinically sewed up is very slow, and blood vessel is involutory bad, thrombosis, the angiostenosis that anastomosis hamartoplasia causes.Especially clinically the identical difficulty that is applied in the minute blood vessel in the microsurgery is bigger.
Summary of the invention
The object of the invention provides a kind of ti-ni shape memory alloy blood vessel anastomat with the Ti-Ni marmem material, the technical problems such as angiostenosis that it has solved, and conventional vascular suture method stitching speed is slow, involutory bad, the thrombosis of blood vessel, anastomosis hamartoplasia cause.
Technical solution of the present invention is:
A kind of ti-ni shape memory alloy blood vessel anastomat, its special character is: shape memory was spiral ti-ni shape memory alloy line 3, is arranged on the semicircle sewing needle of two of ti-ni shape memory alloy line 3 two ends 1, connects two stitching thread 2 of ti-ni shape memory alloy line 3 and two semicircle sewing needles 1 when said blood vessel anastomat comprised 27～33 ℃.
Shape memory was collinear ti-ni shape memory alloy line when above-mentioned stitching thread 2 was 27～33 ℃, and said stitching thread 2 is 60 ° to 90 ° with the angular range of the axis direction of spiral type ti-ni shape memory alloy line 3.
Above-mentioned ti-ni shape memory alloy line 3 and two stitching thread 2 are integral structure, and said two semicircle sewing needles 1 adopt welding manner to be connected with two stitching thread 2.
Above-mentioned ti-ni shape memory alloy line 3 is a helical tubular structure.
Advantage of the present invention is:
1, the present invention utilizes the human vas anastomat of ti-ni shape memory alloy material, and is easy to operate, and suture time is short, can significantly improve the speed of vascular suture.
2, ti-ni shape memory alloy blood vessel anastomat of the present invention; Near " spiral type " support of recovering and expanding into different-diameter under the human body temperature voluntarily, be whole circulus by memorial alloy, play the stent support effect of a machinery; It under the human body temperature condition lasting holding state automatically; Can guarantee the involutory with one heart of blood vessel, make that blood vessel is expert to become cavity, guarantee unobstructed after the vascular anastomosis.
3, ti-ni shape memory alloy blood vessel anastomat of the present invention forms the extruding to the ends of vessels joint, reduces amount of bleeding, impels the blood vessel healing, and operation safety is reliable.
4, ti-ni shape memory alloy blood vessel anastomat of the present invention, unique shape memory function forms lasting automatically the support, can overcome anastomosis, ends of vessels healing back and form the angiostenosis that abnormal pigmentary deposit on the skin trace hypertrophy causes because of hamartoplasia.
5, ti-ni shape memory alloy blood vessel anastomat of the present invention, good biocompatibility can forever be implanted.
6, ti-ni shape memory alloy blood vessel anastomat of the present invention can be applicable to bypass surgery vascular anastomosis and microsurgery vascular anastomosis.

Fig. 3 is the position view of blood vessel anastomat of the present invention in blood vessel;
Wherein: the semicircle sewing needle of 1-, 2-stitching thread, 3-ti-ni shape memory alloy line, 4-blood vessel wall.
The specific embodiment
Ti-ni shape memory alloy blood vessel anastomat of the present invention; Comprise 27～33 ℃ at present shape memory be different-diameter spiral ti-ni shape memory alloy line 3, be arranged on two semicircle sewing needles 1 at ti-ni shape memory alloy line 3 two ends, the two ends of nickel memorial alloy line 3 are connected with two semicircle sewing needles 1 with stitching thread 2 respectively.Ti-ni shape memory alloy line 3 and two stitching thread 2 are integral structure, and two semicircle sewing needles 1 adopt welding manner to be connected with stitching thread 2.Stitching thread 2 is generally straight line, and stitching thread 2 is 60 ° to 90 ° with the angular range of the axis direction of spiral type ti-ni shape memory alloy line 3.
Blood vessel anastomat of the present invention can draw back at normal temperatures, near human body temperature the time, reverts to " spiral type ", is in superelastic.The sewing needle that connects on the stitching thread is used for the stitching of ends of vessels.During stitching; Respectively two sewing needles are thrust the involutory position of ends of vessels, stitching thread is sewed up wearing to interlock around one week of blood vessel continuously, and the extruding that in the straight process of change, forms periphery at stitching thread under the effect of body temperature is involutory; Blood vessel one is all airtight, cut off stitching thread after having sewed up.
Anastomat in the implantable intravascular, memory deformation formation " spiral type " tubular bracket takes place in refresh memory under the human body temperature condition, and blood vessel integral body is strutted.The elasticity tension that on the inwall circumference of blood vessel, is evenly distributed, the all-directional integral support that forms the blood vessel cavity resets, and " spiral type " forms support.The axial shrinkage of " spiral type " is pushed the broken ends of fractured bone of blood vessel, guarantees the stitching of ends of vessels.
Operation principle of the present invention:
Utilize ti-ni shape memory alloy material excellent biological compatibility, have that intensity height, proportion are low, endurance, corrosion-resistant, wear-resistant, nonmagnetic, advantage such as a have no side effect implantable intravascular for a long time.Near under the human body temperature, memorial alloy produces super-elasticity support force and axial tension, and the broken ends of fractured bone of blood vessel is pushed in the contraction of " spiral type ", with two lines ends of vessels is sewed up.
