The invention discloses an ultra-long-distance submarine cable laying device and method, and relates to the technical field of submarine cable laying, the ultra-long-distance submarine cable laying device comprises a base, the bottom of the base is connected with anchoring supporting legs, the upper part of the base is connected with a submarine cable clamping mechanism used for clamping a submarine cable, and the submarine cable clamping mechanism is connected with a sliding block; the sliding block is slidably connected with a sliding rod parallel to the axis of the submarine cable, the base is assembled and connected with a counter-force frame at the rear end of the sliding rod, the counter-force frame is connected with a hydraulic push rod, the output end of the hydraulic push rod is connected with the submarine cable clamping mechanism, and the submarine cable clamping mechanism is driven by the hydraulic push rod to do linear reciprocating motion along the sliding rod; the submarine cable clamping mechanism is used for clamping the submarine cable in the pushing construction process, and then continuous and uniform axial pushing force is applied to the submarine cable through the hydraulic push rod and forms a forward pulling-backward pushing synergistic effect with land side dragging force; the risks of cable stretching, armored layer offset, insulating layer damage and the like caused by too large dragging force are effectively relieved.

A suturing device for surgical operation and a suturing method thereof, comprising a suturing forceps and a suturing needle arranged at the front of the suturing forceps; the material of the suturing needle is nickel-titanium memory alloy material; the suturing forceps drives the suturing needle to complete the suturing operation. The phase change temperature of the suturing needle is 40 degrees Celsius-60 degrees Celsius; the suturing needle is in a straight state before being heated for use, and after being injected with 40 degrees Celsius-60 degrees Celsius warm water for heating, the front end of the suturing needle changes into the shape of a surgical suturing needle. Combined with other structures, it effectively avoids the defects in the prior art that the suturing operation is subject to spatial limitations, making it inconvenient to suturing with bare hands or needle forceps, the hand cannot penetrate deeply into some places, the suturing is not reliable or the suturing is not in place, which affects the surgical effect, is more unfavorable for postoperative recovery, and places with small space are prone to secondary injuries due to accidental contact of instruments.
