[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Reference Figures 1 to 8As shown, an embodiment of the present invention is a nail magazine assembly with a detachable eagle's beak, comprising: an anvil bracket 100, an anvil 200, a nail magazine bracket 300, a nail magazine 400, and an eagle's beak 500. The anvil 200 is made of metal, and one end of the anvil 200 is fixedly connected to the anvil bracket 100. The connection method between the anvil 200 and the anvil bracket 100 is the existing technology, so it will not be described in detail. The nail magazine bracket 300 is hinged to the anvil bracket 100; the connection method between the nail magazine bracket 300 and the anvil bracket 100 is the existing technology, so it will not be described in detail. The nail magazine 400 is installed on the nail magazine bracket 300; a first clamping portion is provided at one end of the nail magazine 400 away from the anvil bracket 100. A second clamping portion is provided at one end of the anvil 200 away from the anvil bracket 100. The olecranon 500 is made of plastic and has a first position where it is snap-fitted to the end of the anvil 200 away from the anvil support 100, and a second position where it is snap-fitted to the end of the staple cartridge 400 away from the anvil support 100. The olecranon 500 can be installed on either the anvil 200 or the staple cartridge 400, depending on surgical needs and the surgeon's usage habits, providing greater flexibility during use. In some special cases, the olecranon 500 can be installed on both the anvil 200 and the staple cartridge 400 simultaneously for operation. However, when the olecranon 500 is installed on both the anvil 200 and the staple cartridge 400 simultaneously, interference between the two olecranons 500 occurs during clamping, making anastomosis impossible. However, the two olecranons 500 can help the surgeon better perform blunt dissection of tissue during surgery, effectively improving the flexibility of using the olecranon 500. Moreover, only the production design of the existing nail magazine 400 needs to be modified, and the nail seat 200, the nail seat bracket 100, and the nail magazine bracket 300 do not need to be modified, which is conducive to reducing manufacturing costs.

[0040] Reference Figure 3 As shown, it can be understood that the side of the nail magazine 400 close to the nail seat 200 is an arc surface. When the nail magazine 400 and the nail seat 200 clamp the tissue, the outer tissue is squeezed less than the inner tissue. Under the premise of ensuring the hemostatic effect of suture, excessive squeezing of the tissue can be avoided, so that the tissue near the suture can still maintain good blood supply, which is beneficial to the patient's postoperative recovery.

[0041] Reference Figure 6As shown, it is understood that the hawk's beak 500 includes a large end and a small end, forming a certain angle between the large end and the small end, and the large end is larger than the small end. The large end of the hawk's beak 500 is provided with a mounting hole 510, which extends in the same direction as the large end of the hawk's beak 500. The mounting hole 510 is provided with a mounting post 511, which is located at the center of the mounting hole 510 and extends in the same direction as the mounting hole 510. The mounting post 511 is connected to the mounting post 511, and the number of the mounting posts 512 can be one or more. The more the number of the mounting posts 512, the more stable the connection between the mounting posts 512 and the groove, but the more difficult it is to disassemble. Therefore, the number of the mounting posts 512 needs to be reasonably selected according to the hardness of the material of the hawk's beak 500. The end of the anvil 200 away from the anvil bracket 100 is provided with a first insertion hole 210 extending along the length of the anvil 200. The sidewall of the first insertion hole 210 is provided with a first groove 211. The number of the first grooves 211 matches the position and number of the clips 512. When the beak 500 is in the first position, the end of the anvil 200 away from the anvil bracket 100 is embedded in the mounting hole 510, the mounting post 511 is embedded in the first insertion hole 210, and the clips 512 are embedded in the first groove 211. The clips 512 embedded in the first groove 211 prevent the beak 500 from being separated from the anvil 200, while the mounting post 511 embedded in the first insertion hole 210 can serve as a limiter. The insertion of one end of the anvil 200 into the mounting hole 510 also serves as a limiter, making the beak 500 more stable and preventing it from shaking during operation.

[0042] Reference Figure 3 、 Figure 4 As shown, it can be understood that the end of the nail magazine 400 away from the anvil bracket 100 is provided with a second insertion hole 410 extending along the length of the nail magazine 400. A second groove 411 is formed on the side wall of the second insertion hole 410. The size and shape of the second insertion hole 410 and the second groove 411 are equal to those of the first insertion hole 210 and the first groove 211. When the groin 500 is in the second position, the end of the nail magazine 400 away from the anvil bracket 100 is inserted into the mounting hole 510, the mounting post 511 is inserted into the second insertion hole 410, and the buckle 512 is inserted into the second groove 411. The insertion of the buckle 512 into the second groove 411 prevents the groin 500 from being separated from the nail magazine 400, while the insertion of the mounting post 511 into the second insertion hole 410 can serve as a limiter. The insertion of one end of the nail magazine 400 into the mounting hole 510 also serves as a limiter, making the groin 500 more stable and preventing it from shaking during operation.

[0043] Reference Figure 4As shown, it can be understood that an annular groove 420 is initially provided on the staple cartridge 400 for the sidewall of the olecranon 500 to fit into. The size of the annular groove 420 matches the size of the sidewall of the large end of the olecranon 500. Since the size of the staple cartridge 400 is larger than that of the anvil 200, the annular groove 420 can be provided on the staple cartridge 400 to limit the olecranon 500, making the connection between the olecranon 500 and the staple cartridge 400 more stable than the connection between the anvil 200 and the staple cartridge 400.

[0044] Reference Figure 4 and Figure 5 As shown, it can be understood that the first socket 210 and the second socket 410 are both cross-shaped, and the shape of the mounting post 511 matches the first socket 210. The first socket 210, the second socket 410, and the mounting post 511 are all configured in a cross shape, which can enhance the stability of the cooperation between the first socket 210 and the mounting post 511, and can enhance the stability of the cooperation between the second socket 410 and the mounting post 511, making the mounting post 511 less likely to shake during operation.

[0045] Reference Figure 5 As shown, it can be understood that the first insertion hole 210 is connected to the side of the anvil 200 near the nail magazine 400. The nail magazine 400 is connected to a cutting knife, which is partially inserted into the first insertion hole 210 and can slide along the extension direction of the first insertion hole 210. The first insertion hole 210 can guide the moving cutting knife and also allow the mounting post 511 on the hawk beak 500 to be inserted into the first insertion hole 210 to fix the hawk beak 500.

[0046] Reference Figure 5 As shown, it is understood that the first groove 211 is defined on the side of the first insertion hole 210 away from the staple cartridge 400, and the second groove 411 is defined on the side of the second insertion hole 410 away from the anvil 200. It is foreseeable that, for ease of processing, the first groove 211 may be provided only on the side of the first insertion hole 210 away from the staple cartridge 400. Because the first groove 211 is defined on the side of the first insertion hole 210 away from the staple cartridge 400, a drill is typically used during hole processing. The drill is inserted through the opening of the first insertion hole 210 on the side of the anvil 200 closer to the staple cartridge 400 to facilitate the processing of the first groove 211. Since the staple cartridge 400 is typically injection molded, the annular groove 420 and the second groove 411 of the second insertion hole 410 can be directly formed by injection molding of the staple cartridge 400.

[0047] Reference Figure 1 and Figure 2As shown, it can be understood that the angle of the bend of the olecranon 500 matches the shape of the end of the staple cartridge 400 away from the anvil support 100, and the shape of the end of the staple cartridge 400 away from the anvil support 100 matches the angle of the bend of the olecranon 500. The end of the staple cartridge 400 away from the anvil support 100 and the end of the anvil 200 away from the anvil support 100 are both configured as inclined surfaces to cooperate with the olecranon 500 in manipulating tissue.

[0048] Reference Figure 8 As shown, it can be understood that the shape of the bottom wall of the mounting hole 510 matches the shape of the end of the anvil 200 away from the anvil bracket 100. The end of the anvil 200 away from the anvil bracket 100 is provided with a chamfer. In order to improve the stability of the connection between the hawk beak 500 and the anvil 200, the shape of the bottom wall of the mounting hole 510 is set to completely fit the anvil 200.

[0049] Usage steps: To install the beak 500 on the anvil 200, align the anvil 200 with the mounting hole 510 on the beak 500, insert the mounting post 511 into the first insertion hole 210, and insert the buckle 512 into the first groove 211 to secure the beak 500 to the anvil 200. To remove the beak 500 from the anvil 200, the operator pulls out the beak 500 to separate it from the anvil 200. To install the beak 500 on the nail magazine 400, align the nail magazine 400 with the mounting hole 510 on the beak 500, and insert the mounting post 511 into the second insertion hole 410, and insert the buckle 512 into the second groove 411 to secure the beak 500 to the nail magazine 400. The steps of removing the olecranon 500 from the nail magazine 400 are as follows: the operator pulls out the olecranon 500 to separate the olecranon 500 from the nail magazine 400 .

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
