The invention belongs to the technical field of surgical instruments, and particularly relates to a surgical operation blood vessel suturing device convenient to hold, which comprises a shell, a thread pushing rod, a threading assembly and a thread cutting assembly, the thread pushing rod is provided with a thread hole for a suture thread to penetrate in and out, the threading assembly comprises a connecting rod fixedly mounted on the shell, and a thread cutting assembly is arranged on the connecting rod; the wire pushing rod is mounted at the end part of the connecting rod; the cover plate is rotationally mounted on the wire pushing rod, and the cover plate and the wire pushing rod are combined to form a cylindrical structure with a hemispherical end part; through the arrangement of the threading assembly, threading does not need to be conducted by depending on a traditional stay wire rod, threading positioning can be completed only through the simple steps of opening the cover plate, embedding a suture line and closing the cover plate, repeated disassembly and assembly and precise insertion operation of the stay wire rod are omitted, the operation step of single-time suture is greatly reduced, handheld operation is facilitated, and the operation efficiency is improved. The device is especially suitable for multi-vessel suturing scenes, and the operation burden of doctors is remarkably reduced.
