Description

Technical Field

[0001] The present invention relates to the technical field of staplers, and in particular to a portable first aid stapler and a use method thereof. Background Art

[0002] A skin stapler is a medical device that replaces manual suturing of epidermal wound tissue after surgery. When in use, the stapler handle is pressed, and the staple pressing plate pushes the staples in the staple storage box to the staple outlet position, and the staple pushing piece pushes the staples out of the staple outlet to connect with the human skin for suture.

[0003] The existing Chinese patent with announcement number CN103431884B discloses an open flat skin suturer, in which a movable handle is rotatably connected to a fixed handle, a nail storage box is fixedly connected to the front end of the fixed handle, a nail feeder is fixedly connected between the fixed handle and the nail storage box, a nail pushing plate is slidably connected between the nail feeder and the nail storage box, the upper surface of the nail pushing plate is connected to the top of the movable handle, and the lower surface is connected to the nail storage box through a compression spring; a nail magazine plate is fixedly connected to the lower end of the nail storage box, an upturned nail blocking plate is provided at the front end of the nail magazine plate, suture nails and nail pressing mechanisms are installed on the upper side of the nail magazine plate, and a cover plate is fixedly connected to the lower end of the nail magazine plate.

[0004] However, the above-mentioned skin stapler has the following disadvantages: 1. The stapler of the stapler is the same as the staplers on the market, and the stapler outlet of the stapler is arranged at the front bottom of the stapler. When in use, the movable handle and the fixed handle are pressed up and down relative to each other, so that the stapler pusher pushes the stapler out of the stapler outlet. When the stapler is pushed out, the two ends of the stapler are bent inwardly by the stapler blocking plate. When medical workers use the stapler to suture the affected area, they often need to hold the stapler by hand, and then use a large clamping force to push out and bend the stapler. However, the above-mentioned stapler adopts a bottom-mounted stapler outlet design, which makes it difficult for the stapler to be pushed out when suturing the affected area. The upper body of the stapler blocks the staple outlet and the eyes of the medical worker, causing the staple outlet to be blocked by the main body of the stapler during suturing. The medical worker needs to lean sideways to observe whether the staples pushed out of the staple outlet are in close contact with the wound, which is rather troublesome. In the case where the pressing force required by the staples themselves is relatively large, long-term sideways work will also make the medical worker feel physically uncomfortable. 2. This stapler is the same as staplers on the market in that multiple staples are laid flat on the same horizontal plane in a staple storage box. The flat-laying staple design results in a small staple storage capacity of the staple storage box, requiring more frequent addition of staples or direct replacement of the stapler loaded with staples. Summary of the invention

[0005] The purpose of the present invention is to provide a portable emergency suturing device, which can provide a clearer visual field and improve the capacity of storing suturing nails when suturing wounds.

[0028] S3: The handle pushes the nail pressing plate through the transmission assembly to cooperate with the bending part to bend the two ends of the suture nail at the nail outlet, thereby suturing the wound;

[0029] S4: After the suture nails at the nail outlet are bent by the nail pressing mechanism and the wound is sutured, the pressing force on the handle is removed to reset the nail pressing plate. At this time, the nail feeding mechanism pushes the suture nails in the storage section to be transported to the nail outlet through the reversing section in sequence, so as to replenish the suture nails at the nail outlet;

[0030] S5: Repeat steps S1-S4 to achieve continuous suturing of the wound.

[0031] In summary, the present invention has the following beneficial effects:
