BEST MODE FOR CARRYING OUT THE INVENTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings. 1 to 5, the present invention includes a needle card 1 and a grooved card 5 which are used in pair with each other, and the needle card 1 is placed inside the longitudinal slit 11 of the blood vessel. The slotted card 5 is fastened to the outer wall of the blood vessel 10 opposite to the needle card 1. The needle card 1 is provided with a plurality of needles 2 at both ends of the longitudinal slit 11 of the blood vessel 10, and the needles 2 are longitudinally spaced. Arranged, the grooved card 5 is provided with two rows of longitudinal through holes 6 at positions opposite to the needle 2 provided on the needle card 1.

[0022] In the present invention, referring to FIG. 1 and FIG. 2, the needle card 1 is provided with a pull wire 3, which is a strip structure fixed on the top of the needle card 1. Referring to Figure 3 and Figure 4, the top of the slotted card 5 is provided with a cable fixing mechanism 7 which is a strip card which is laid and fixed on the top of the slotted card 5, the strip card The upper jaw is provided with a slot 8 extending longitudinally and through the body of the slotted card 5, the slot 8 being used in conjunction with the cable 3 provided on the card 1 for the card, and the cable 3 is passed through the slot 8 of the cable fixing mechanism 7 and After tightening, the needle card 1 and the slotted card 5 can be pressed together. As a further improvement, in order to prevent the cable 3 from being slid out of the slot 8 of the cable fixing mechanism 7, a plurality of lateral anti-slip grooves 4 are provided on the side of the ribbon structure of the cable 3, and the anti-slip groove 4 The corresponding through-wire fixing mechanism 7 and the notch 8 of the slotted card 5 are provided with hooks 9 whose ends are upwardly provided. When the pull wire 3 passes up through the notch 8吋, the pull wire 3 is easily penetrated because its penetration direction is compliant with the hook ₉ . When the cable 3 is tightened, since the cable 3 is reversed from the sliding direction of the slot 8 and the hook 9 is provided, the horizontal anti-skid slot 4 on the cable 3 is caught on the hook 9, so that the tightened cable 3 is difficult to be tightened. Slide out. This structural arrangement ensures that the inner and outer portions of the blood vessel 10 can be fastened and locked after the pull wire 3 is cut.

[0023] Of course, in the present invention, the anti-slip groove 4 and the hook 9 having the locking function are provided on the wire 3 and the notch 8, and can also be disposed on both sides of the wire 3, and are disposed on the wire fixing mechanism 7 and the belt. The two sides of the notch 8 of the slot card 5, or any existing method of locking effect, are not limited to the manner in which the anti-slip groove 4 and the hook 9 are provided on the one side of the present invention.

6 is a schematic view of a process of use, showing a longitudinal slit 11 of a blood vessel to be sutured. After using the 吋, after the end of the vascular end, the needle card 1 is directly placed into the vascular cavity with the help of the microsurgical instrument placing the handle 12, and the parts to be sutured on both sides are hooked with the fine needle 2 Then, the push wheel 13 placed on the handle 12 is pushed, and the slotted card 5 placed at the end of the handle 12 is fastened to the outer wall of the longitudinal slit 11 of the blood vessel 10 until the needle card 1 and the slotted card 5 are respectively set. Some fine needles 2 and through holes 6 are fixed and fixed inside and outside the longitudinal slit 11. Then, the wire 3 is tightened, the inner and outer portions of the blood vessel 10 are fastened and locked, and the wire 3 is cut. Then, the next needle card 1 is placed, and the operation is repeated in the order from the distal end to the proximal end, and the needle card 1 and the grooved card 5 used in pairs are arranged in the inner wall of the longitudinal incision 11 of the blood vessel 10 until the blood vessel is sutured. Finally, the longitudinal incision 11 of the internal carotid artery is closed. Referring to FIG. 5 and FIG. 7, the needled card 1 and the extravascular grooved card 5 in the longitudinal slit 11 of the suture are arranged in groups, and are all stacked, which can ensure that the whole device can be inside and outside the blood vessel 10. Completely closing the vascular end, in the operation of sutured longitudinal incision 11 such as carotid endarterectomy, can also play a role in guiding the direction of blood flow. The needle card 1 and the slotted card 5 in the utility model are all absorbable biological products, and can be absorbed by the human body after the operation. At the same time, the card with the needle card and the slotted card of the utility model can be bent according to the curvature of the blood vessel wall, and can be applied to the end-end anastomosis of the remaining large blood vessels after the arc curvature and the bending direction are changed, thereby expanding the utility model. The scope of application is not described herein by way of example.

It should be understood that the specific embodiments of the present invention are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, which is obvious to those skilled in the art. The modifications are also within the scope of the present invention. .
