However, the embodiments described are not intended to limit the present invention.

[0013] It should be noted that when a component is referred to as being "set on" or "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is referred to as being "fixed to" another component, or "fixedly connected" to another component, the fixing method can be detachable or non-detachable. When a component is considered to be "connected" or "rotatably connected" to another component, it can be directly connected to the other component or there may be an intermediate component. 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.

[0014] 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.

[0015] In this invention, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0016] This application relates to a staple cartridge for a skin suture device. The base plate of the staple cartridge is connected to the upper shell of the staple cartridge via a detachable connection. During the assembly of the staple cartridge, there is no need to use ultrasonic welding equipment, reducing the investment in production equipment. At the same time, the base plate of the staple cartridge is detachable, which facilitates the recycling of the staple cartridge. After recycling and cleaning, the base plate of the staple cartridge can be removed and suture staples can be replenished, thereby realizing the reuse of the staple cartridge, reducing costs, and also reducing the medical costs for patients.

[0017] Figure 1 This is a three-dimensional schematic diagram of the staple cartridge according to an embodiment of this application; the staple cartridge of the assembled skin suture device includes a staple cartridge upper shell 1, with side plates 10 symmetrically arranged on both sides of the lower end of the staple cartridge upper shell 1. A plurality of locking holes 100 are evenly distributed on the side plates 10 along the length direction of the staple cartridge upper shell 1. Specifically, in this embodiment, the side plates are provided with 4 locking holes, which are square and penetrate the inner and outer walls of the side plates. The device also includes a staple cartridge bottom plate 2, with a plurality of locking buckles 20 arranged along the length direction on the surface of the staple cartridge bottom plate 2. The locking buckles 20 are connected to the locking buckles... Corresponding to hole 100, the locking buckle and locking hole cooperate to connect the staple cartridge bottom plate and the staple cartridge upper shell. The locking buckle is assembled and fitted in the locking hole, thereby connecting the staple cartridge plate and the staple cartridge upper shell. The staple cartridge bottom plate is used to fix the various components inside the staple cartridge upper shell. Since the locking hole penetrates the inner and outer walls of the side plate, the locking buckle can be driven to separate from the locking buckle on the outside of the side plate by a corresponding jig, realizing the disassembly of the staple cartridge bottom plate and the staple cartridge upper shell. This achieves non-destructive disassembly, facilitates the recycling and reuse of the staple cartridge, and reduces costs.

[0018] The staple cartridge base plate 2 has guide plates 21 symmetrically arranged along its length in the middle. Guide bosses 210 are provided on the inner sidewalls of the guide plates. The upper surface of the guide bosses is used to support the pusher plate. The two guide plates are used to limit the pusher plate. Furthermore, the structure of the staple cartridge base plate is defined. The two guide side plates first limit the width of the pusher plate. Secondly, the guide bosses support the lower end of the pusher plate and limit its height. Limiting the pusher plate in both directions ensures that the pusher plate can accurately act on the nail feet on both sides after the staple is formed, thus achieving a better pusher effect.

[0019] It also includes a front limiting plate 211 and a rear limiting plate 212. The lower ends of the front limiting plate and the rear limiting plate are connected to the guide boss, and the side ends of the front limiting plate and the rear limiting plate are connected to the guide plate. Furthermore, the front limiting plate and the rear limiting plate are configured to limit the distance of the pusher plate's forward and backward movement.

[0020] Furthermore, a thickened area 220 is provided on the staple cartridge base plate 2 between the two guide bosses 210. The thickened area increases the thickness of the staple cartridge base plate, and the strength of the base plate is also improved accordingly, thereby ensuring the structural strength of the entire staple cartridge after assembly.

[0021] Furthermore, the thickened area 220 of the nail cartridge bottom plate 2 is provided with a number of weight-reducing holes 2201. The weight-reducing holes can reduce the weight of the nail cartridge bottom plate on the one hand, and reduce the amount of material used on the other hand, thereby reducing the material cost of the product. Alternatively, the weight-reducing holes can prevent the formation of long strip-shaped thick material areas, overcome the problem of shrinkage cavities that may occur during injection molding, and ensure the quality of the product.

[0022] Furthermore, a groove 23 corresponding to the locking buckle is provided on the side of the staple cartridge base plate 2. The bottom surface of the groove 23 is flush with the surface of the locking buckle. The groove removes the connection between the surface of the locking buckle and the staple cartridge base plate, reduces the constraint of the staple cartridge base plate on the locking buckle, and allows the locking buckle to have a larger deformation range. This facilitates the assembly between the staple cartridge base plate and the upper shell of the staple cartridge, and also makes disassembly easier in the later disassembly process.

[0023] In summary, this utility model has the following beneficial effects: This application relates to a staple cartridge for a skin suture device. The base plate of the staple cartridge is connected to the upper shell of the staple cartridge via a detachable connection. During the assembly of the staple cartridge, there is no need to use ultrasonic welding equipment, reducing the investment in production equipment. At the same time, the base plate of the staple cartridge is detachable, which facilitates the recycling of the staple cartridge. After recycling and cleaning, the base plate of the staple cartridge can be removed and suture staples can be replenished, thereby realizing the reuse of the staple cartridge, reducing costs, and also reducing the medical costs for patients.

[0024] 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.
