Problems solved by technology

[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

Embodiment Construction

[0024] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] according to Figure 1-9 Shown, as an example, is a femoral artery puncture needle. Including the casing 1, the catheter sheath 2 is fixed in the casing 1. The installation end of the push needle tube 3 and the middle part of the arc-shaped puncture needle 4 can be fixed into an integral structure by existing connection methods such as threaded connection. The operating end of the needle pusher tube 3 is provided with a trigger hole 301 , the suture 5 is a polypropylene suture, and the midd...

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...
