[0028] The present utility model relates to a preferred embodiment of a plug-in beak.

[0029] Please refer to Figure 1 and Figure 4 , the plug-in beak includes a beak body 100, and the beak body 100 is connected to the end of the anvil 200 in a plug-in manner.

[0030] In an exemplary embodiment, as Figure 2 shown, the distal end of the beak body 100 has an extension part 120, and the proximal end of the beak body is obliquely cut to form a first guiding inclined surface 110, and a plug-in buckle 130 is arranged on the first guiding inclined surface 110.

[0031] As Figure 3As shown, the end of the staple cartridge 200 is beveled to form a second guiding bevel surface 210, on which there is a plugging port 220, and an inner card slot 230 for accommodating the plugging buckle 130 is arranged at the end of the staple cartridge 200.

[0032] During installation, the plugging buckle 130 moves through the plugging port 220 and inserts into the inner card slot 230 of the staple cartridge 200 to realize the quick connection and fixation between the eagle beak body 100 and the staple cartridge 200.

[0033] Furthermore, the second guiding bevel surface 210 at the end of the staple cartridge 200 is arranged to be capable of fittingly engaging with the first guiding bevel surface 110 at the proximal end of the eagle beak body 100. Through the cooperation of the two guiding bevel surfaces, it can be ensured that during the connection process between the eagle beak body 100 and the staple cartridge 200, the plugging buckle 130 on the eagle beak body 100 can quickly slide to the position of the plugging port 220 for plugging, completing the quick engagement between the eagle beak body 100 and the staple cartridge 200.

[0034] As an optional implementation manner of the present utility model, the extension part 120 and the plugging buckle 130 of the eagle beak body 100 are integrally formed.

[0035] In an exemplary embodiment, the extension part 120 is arranged to be inclined, and the inclination angle of the extension part 120 is 10 - 20°, which can adapt to narrow blood vessels and tissue spaces, providing the possibility for surgical operations at narrow positions.

[0036] In an exemplary embodiment, the plugging buckle 130 includes a first support body 131 and a second support body 132 extending outward from the first guiding bevel surface 110, and the first support body 131 and the second support body 132 are arranged at an angle, respectively extending obliquely upward and obliquely downward.

[0037] Furthermore, the end of the first support body 131 has an upward protruding engaging protrusion 133, and the end of the second support body 132 has a downward protruding engaging protrusion 134.

[0038] As an optional implementation manner of the present utility model, the inner card slot 230 includes a guiding slot 231 and a clamping slot 232. The guiding slot 231 is arranged to be capable of accommodating the first support body 131 and the second support body 132, and the clamping slot 232 is arranged to be capable of accommodating the engaging protrusion 133 and the engaging protrusion 134.

[0039] Furthermore, as Figure 5As shown, an abutting surface 135 is formed at the connection between the first support body 131 and the first engaging protrusion 133, an abutting surface 136 is formed at the connection between the second support body 132 and the second engaging protrusion 134, a abutting position 233 is formed at the connection between the guiding slot 231 and the clamping slot 232, and the abutting surface 135 and the abutting surface 136 respectively abut against the upper and lower sides of the abutting position 233.

[0040] As an optional implementation manner of the present utility model, the eagle beak body 100 is made of an elastic material or a soft material, which can deform when the eagle beak body 100 is connected to the anvil 200 until the plug-in buckle 130 is completely inserted into the inner card slot 230 of the anvil 200.

[0041] The present utility model also relates to a stapler, including the plug-in eagle beak described above, and the plug-in eagle beak is detachably connected to the end of the anvil.

[0042] The installation process of the plug-in eagle beak and the anvil is as follows:

[0043] When the eagle beak body 100 moves towards the end of the anvil 200, the whole plug-in buckle 130 moves forward through the plug-in port 220. At this time, the first engaging protrusion 133 and the second engaging protrusion 134 will be compressed and deformed, and the first engaging protrusion 133 and the second engaging protrusion 134 drive the first support body 131 and the second support body 132 to continue to move forward through the guiding slot.

[0044] Until the first engaging protrusion 133 and the second engaging protrusion 134 fall into the clamping slot 232. At this time, the abutting surface 135 and the abutting surface 136 respectively abut against the upper and lower sides of the abutting position 233, and the connection and installation of the eagle beak body 100 and the anvil 200 are completed.

[0045] The beneficial effects of the plug-in eagle beak and the stapler of the present utility model are:

[0046] The eagle beak body can be directly plugged in and unplugged, and the installation operation with the anvil is more rapid and smooth, realizing the detachable and rapid connection between the eagle beak and the anvil, realizing the rapid disassembly and assembly in different scenarios, and improving the flexibility and practicability of the stapler.

[0047] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
