femoral artery puncture and suturing device

Abstract

The invention provides a femoral artery puncture suture device. The installing end of a needle pushing tube is installed in the middle of an arc-shaped puncture needle. Two ends of a suture line are respectively fixed to two ends of the arc-shaped puncture needle. The middle of the suture line is fixed to the operating end of the needle pushing tube. The arc-shaped puncture needle is made from memory alloy. The arc-shaped puncture needle is arranged in a catheter sheath, and needle points at two ends are in inward stress-compressed shapes. When the needle pushing tube pushes the arc-shaped puncture needle output of the catheter sheath, the needle points at the two ends of the arc-shaped puncture needle are outwards released to be in memory shapes. The arc-shaped puncture needle of the femoral artery puncture suture device is put in a femoral artery puncture port by using the memory alloy and penetrates out from inside to outside, the suture line penetrates out, accordingly inner diaphragm floating caused by artery atherosclerotic plaque lifting due to threading from outside to inside is avoided, interlayer and secondary thrombosis formation possibly occurred under blood impact is avoided, and accordingly the complication of arterial occlusion is avoided.

Description

technical field [0001] The present invention relates to a needle holder or a needle or a bag of suturing materials for suturing wounds, in particular to a femoral artery puncture and suturing device. Background technique [0002] The more common method of interventional therapy is to puncture the skin at the root of the thigh, insert a special catheter into the femoral artery, and then insert it into the abdominal aorta. After the arterial interventional therapy, the above wound needs to be sutured. Most suturing operations rely on vascular surgeons to perform manual pressure or press high-pressure gauze to stop bleeding, which greatly wastes the working time of vascular surgeons, and if the manual manual pressure is a little careless, the blood will spurt due to the pressure of the artery. out of the body. The existing blood vessel suturing device is mainly based on needle and thread suture, and the principle is similar to ordinary suturing needles, but because all operati...

[0002] The more common method of interventional therapy is to puncture the skin at the root of the thigh, insert a special catheter into the femoral artery, and then insert it into the abdominal aorta. After the arterial interventional therapy, the above wound needs to be sutured. Most suturing operations rely on vascular surgeons to perform manual pressure or press high-pressure gauze to stop bleeding, which greatly wastes the working time of vascular surgeons, and if the manual manual pressure is a little careless, the blood will spurt due to the pressure of the artery. outside the body

The existing blood vessel suturing device is mainly based on needle and thread suture, the principle is similar to that of ordinary suture needles, but since all operations need to be completed in the body, and two sets of devices are required to complete the operation, the operation is more cumbersome

And the existing suturing device all needs to run the needle from the outside to the inside, and in the process of running the needle from the outside to the inside, if figure 1 As shown, it is easy to lift the atherosclerotic plaque to form a floating intima sheet, which is likely to form dissection and secondary thrombosis under the impact of blood flow, resulting in arterial occlusion
