The terms "vertical," "horizontal," "left," "right," "upper," "lower," and similar expressions used are for illustrative purposes only and do not represent the only possible implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] In this invention, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0028] This application relates to a skin suture device, specifically a fixing structure between the suture plate and the suture cartridge housing. This fixing structure can pre-fix the suture plate, ensuring a stable and reliable connection between the suture plate and the suture cartridge housing before the suture cartridge base plate is installed. This allows for better support of the installed components and overcomes the potential problems of fixing the suture plate solely with the suture cartridge base plate in the prior art.

[0029] See Figure 1As shown, the staple plate fixing structure of the skin suture device includes a staple cartridge housing 1, with a mounting groove 10 on the bottom surface of the staple cartridge housing 1. Symmetrical support surfaces 100 are provided on both sides of the mounting groove 10, and multiple positioning posts 101 are arranged along the length direction on the support surfaces 100. It also includes a staple plate 2, with grooves 20 formed on both sides along the length direction of the staple plate 2.

[0030] The front end of the nail cartridge housing 1 is symmetrically provided with mounting holes 11 that extend to the support surface. A groove 1010 is provided on the surface of the positioning post 101 near the mounting hole 11. The groove 1010 is flush with the support surface 100. It also includes a plug plate 3. The plug plate 3 is provided with a plug rod 30 that mates with the mounting hole 11. The edge of the groove 20 of the nail plate 2 is embedded in the groove 1010 of the positioning post. The end of the plug rod 30 is exposed on the support surface and the side wall of the plug rod 30 abuts against the end face of the nail plate.

[0031] This invention improves the staple cartridge of a skin suture device. The edge of the staple plate's groove is embedded into the slot of the positioning post, achieving a limiting position perpendicular to the slot direction. Then, the end of the insertion rod abuts against the end face of the staple plate. Since the insertion rod, after being assembled with the mounting hole, can only move along the axis of the mounting hole, the insertion rod abuts against the end face of the staple plate, further locking the staple plate in the slot embedding direction. After this locking mechanism, a stable and reliable connection is formed between the staple plate and the staple cartridge housing. All components installed between the staple plate and the staple cartridge housing are effectively fixed, facilitating the subsequent assembly of other components and preventing components from easily detaching during production transfer.

[0032] Furthermore, the front end of the nail plate 2 is provided with a relief notch 21, and the side wall of the insertion rod 30 abuts against the wall surface of the relief notch 21. The relief notch forms two right-angled relief notch walls, and the side wall of the insertion rod abuts against the two relief notches at the same time, thereby positioning the nail plate in two directions and ensuring the positioning accuracy between the nail plate and the nail cartridge housing.

[0033] The mounting holes 11 are located on both sides of the forming plate 12 of the staple cartridge housing. The staple cartridge housing 1 has symmetrically formed first supporting slopes 13 for supporting the lower end of the insert plate. The surface used to support the lower end of the insert plate is designed with slopes. When the lower end of the insert plate is attached to the first supporting slope, the insert plate is parallel to the forming plate, which can better guide the movement of the staple forming plate.

[0034] Positioning side plates 31 extend rearward from both ends of the plug plate 3 along its length. The nail cartridge housing 1 is provided with a second supporting surface 14 that supports the bottom surface of the positioning side plates 31. The extended positioning side plates position the plug plate in the width direction and also enhance the structural strength of the plug plate and other accessories connected to it. At the same time, the bottom surface of the positioning side plates fits into the second supporting surface to form multiple positioning fulcrums, thereby improving the overall load-bearing capacity of the plug plate.

[0035] The nail cartridge housing 1 located next to the first supporting inclined surface 13 is provided with a supporting step surface 15. The surface of the plug plate 3 is provided with a set of supporting plates 32. The side wall of the supporting plate 32 abuts against the side wall of the supporting step surface, and the bottom wall of the supporting plate abuts against the bottom surface of the supporting step surface.

[0036] Furthermore, the upper end of the plug plate 3 is provided with an inclined plate 33, which is used to press against the surface of the molding plate and guide the molding plate.

[0037] In summary, this utility model has the following beneficial effects:

[0038] This invention improves the staple cartridge of a skin suture device. The edge of the staple plate's groove is embedded into the slot of the positioning post, achieving a limiting position perpendicular to the slot direction. Then, the end of the insertion rod abuts against the end face of the staple plate. Since the insertion rod, after being assembled with the mounting hole, can only move along the axis of the mounting hole, the insertion rod abuts against the end face of the staple plate, further locking the staple plate in the slot embedding direction. After this locking mechanism, a stable and reliable connection is formed between the staple plate and the staple cartridge housing. All components installed between the staple plate and the staple cartridge housing are effectively fixed, facilitating the subsequent assembly of other components and preventing components from easily detaching during production transfer.

[0039] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
