Description

Technical Field

[0001] The utility model relates to the technical field of suturing devices, in particular to a portable first-aid suturing device. Background Art

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

[0003] The existing Chinese patent with announcement number CN103431884B discloses an open flat skin suture device, 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 by 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 staples and a nail pressing mechanism 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 suture device has the following disadvantages: 1. The stapler is the same as the staplers on the market, and the staple outlet of the stapler is arranged at the bottom of the front end 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 staple outlet. When the stapler is pushed out, the two ends of the stapler are bent inward by the stapler blocking plate. When medical workers use the stapler to suture the affected area, they often need to hold the stapler in their hands and then use a large clamping force to push out and bend the stapler. However, the above-mentioned stapler adopts a bottom-mounted staple outlet design, which makes it difficult to suture the affected area. The upper body of the stapler is blocked between the staple outlet and the eyes of the medical worker, resulting in the staple outlet being 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 contact with the wound, which is rather troublesome. In the case that the staples themselves require a large pressing force, long-term sideways work will also make the medical worker feel physically uncomfortable. 2. This stapler, like staplers on the market, adopts the method of laying multiple staples flat on the same horizontal surface in the 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 filled with staples.
