It should be noted that the handle is not necessary in the present technical solution, and the working principle of the present invention is preferably described in detail only in the present embodiment, so that the detailed structure thereof will not be described herein. In other embodiments, a snap ring or the like may be used to fasten the first left and second left needle pushers 20 and 21, and the first right and second right needle pushers 30 and 31, respectively.
The working principle is as follows:
as shown in fig. 3-6, two ends of the central unit 1 sleeved with the left needle pusher and the right needle pusher are respectively butted into two segments of broken blood vessels 5, at this time, the blood vessels 5 are respectively sleeved on the left butt-joint part 12 and the right butt-joint part 13, the opening of the left needle-threading slot 10 on the left butt-joint part 12 and the opening of the right needle-threading slot 11 on the right butt-joint part 13 are both covered by the corresponding blood vessels 5, at this time, the left needle pusher and the right needle pusher are driven by the handle to slide towards the middle part, wherein the inner surface of the left conical cavity 22 in the left needle pusher is butted with the crown part of the left suture needle 14, the inner surface of the right conical cavity 32 in the right needle pusher is butted with the crown part of the right suture needle 15, and with the continuous relative movement of the left pusher and the right pusher, the left suture needle 14 and the right suture needle 15 are gradually pushed into the left needle-threading slot 10 and the right needle-threading slot 11 by the action of the respective corresponding inner surfaces, the needle point parts of the two sections of broken blood vessels 5 gradually butt joint together and are sutured by pulling the two ends of the suture thread 4 slowly to finish the anastomosis of the blood vessels 5.
The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
