[0002] Anastomosis devices are typically divided into two parts: the main body and the staple cartridge assembly. The main body is the actuating mechanism, which performs operations such as clamping tissue, firing and cutting for anastomosis, and repositioning. The staple cartridge assembly is the direct operating component for anastomosing tissue, including the staple cartridge assembly and the staple seat assembly. The staple cartridge assembly is used to hold the staples for suturing tissue, and the staple seat assembly is used for staple shaping to better anastomose tissue.

[0003] like Figures 1-3 As shown, existing anvil assemblies generally include a connected abutment plate 10' and a bracket 20'. Due to inconsistencies in stapler models from different manufacturers and variations in the surgical tissue environment, the structures of anvil assemblies often differ. For example, some manufacturers produce anvil assemblies with a flat front end, while others produce those with a beveled front end or other structures. In actual production, if stapler component suppliers fail to accurately obtain market information and mass-produce a certain type of anvil assembly, it can easily lead to product inventory backlog. Therefore, how to avoid product inventory backlog is an urgent problem to be solved.

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0028] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0029] Combination Figure 4 and Figure 5 As shown, a detachable anvil assembly of the present invention is a preferred embodiment, consisting of a general body 10 and replaceable parts 20. In the actual production process, the replaceable parts 20 with different structures can be replaced according to actual needs. For example, according to market demand, the replaceable parts 20 in the produced anvil assembly can be replaced with other structures to meet market demand, thereby avoiding the backlog of product inventory.

[0030] Specifically, such as Figure 4As shown, the detachable anvil assembly includes a universal body 10 and a replaceable component 20, which is detachably connected to the universal body 10. The universal body 10 has several anvil grooves 12 configured to compress and deform the staples. Simultaneously, one end of the universal body 10 has a first mounting portion 11, and the replaceable component 20 has a second mounting portion 21 that cooperates with the first mounting portion 11. With the cooperation of the first mounting portion 11 and the second mounting portion 21, the replaceable component 20 can be detachably connected to the universal body 10, facilitating the replacement of different structures of the replaceable component 20 according to actual needs. The detachable anvil assembly of this invention, through its detachable structural design, allows for the replacement of the replaceable component 20 according to market demand, thereby avoiding product inventory buildup.

[0031] In this embodiment, as Figure 5 As shown, the first mounting part 11 preferably has a plug-in groove, and the second mounting part 21 preferably has a protrusion that can be inserted into the plug-in groove. The engagement of the plug-in groove and the protrusion allows for a detachable connection between the replaceable component 20 and the universal body 10. Of course, in other embodiments, the first mounting part 11 may also employ other structures, as long as they enable a detachable connection between the two.

[0032] like Figure 6 As shown, the universal body 10 includes a backing plate 10a and a bracket 10b. The backing plate 10a has a first end face and a second end face disposed opposite each other in its thickness direction. The first end face has a plurality of anvil grooves 12 for compressing and deforming the staples. The bracket 10b is located on one side of the second end face of the backing plate 10a and is connected to the backing plate 10a. The connection between the backing plate 10a and the bracket 10b forms the aforementioned insertion groove.

[0033] In this embodiment, combined with Figure 5 and Figure 6 As shown, the bracket 10b and the backing plate 10a are connected by welding. Using welding makes the connection between the two more stable.

[0034] Furthermore, the insertion groove formed after the abutment plate 10a and the bracket 10b are connected can not only accommodate the replaceable component 20, but also hold other components, such as a cutting blade. In a specific implementation, the abutment plate 10a is also provided with an opening 13 for the cutting blade to move, and the opening 13 extends along the length of the abutment plate 10a. When the cutting blade is assembled into the insertion groove, it can move under the action of the opening 13 to cut the tissue.

[0035] Furthermore, such as Figure 6As shown, the bracket 10b includes an arc-shaped portion, that is, the bracket 10b is arc-shaped when viewed in cross-section. When the abutment 10a is connected to the bracket 10b, an arc-shaped insertion groove can be formed under the action of the arc-shaped portion, so as to facilitate detachable connection with the replaceable component 20.

[0036] like Figure 7 As shown, the replaceable component 20 includes a body, and the protrusion (i.e., the first mounting portion 21) extends outward from the body. Furthermore, the replaceable component 20 can adopt different structures according to actual needs, such as... Figure 4 and Figure 5 As shown, the body of the replaceable component 20 includes a bevel 22. In the direction away from the universal body 10 (e.g., Figure 5 (From left to right), the inclined surface 22 gradually moves away from the anvil groove 12 (e.g.) Figure 5 The slope is from top to bottom. By using the slope 22, it is easier for the anvil assembly to enter the tissue.

[0037] Of course, in other embodiments, the replaceable component 20 may also include a plane. When the replaceable component 20 is connected to the universal body 10, this plane may be coplanar with the surface of the abutment 10a, that is, the plane of the body and the first end face of the abutment 10a are coplanar. This coplanar arrangement facilitates the movement of the abutment assembly.

[0038] In some embodiments, the universal body 10 and the replaceable component 20 can be installed and welded together as needed for the device.

[0039] A preferred embodiment of this utility model provides a detachable anvil assembly, comprising a universal body 10 and replaceable components 20. Since the universal body 10 has a universal structure, suitable replaceable components 20 can be selected and installed on the universal body 10 structure, avoiding inventory buildup of the entire anvil assembly.

[0040] In addition, for the anvil assembly that already has inventory, its front end can be cut to form the universal body 10 described in this utility model, and the appropriate replaceable part 20 described in this utility model can be assembled according to actual needs. On the one hand, material costs can be saved, and on the other hand, extensive welding processes can be avoided (because the universal body 10 and the replaceable part 20 are assembled and connected, or only the connection part is welded after assembly, reducing welding steps), which greatly saves production time.

[0041] This utility model also discloses a nail box assembly, including the aforementioned detachable nail seat assembly, which can avoid product inventory backlog.

[0042] This utility model also discloses a stapler, including a main body and the aforementioned stapler assembly. The stapler assembly is connected to the main body, and the main body can control the stapler assembly to perform tasks such as cutting and suturing tissue. This stapler can also avoid the accumulation of product inventory.

[0043] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
