[0021] See also Figures 1 to 4 A detachable beak assembly of an anvil seat includes a buckle 1 and a beak 2. The buckle 1 has a connecting protrusion 11, and the beak 2 has a mounting hole 21 that matches the connecting protrusion 11. The connecting protrusion 11 is inserted into the mounting hole 21 so that the buckle 1 and the beak 2 are rotatably connected. The connecting protrusion 11 is a cylindrical structure, and the connecting protrusion 11 is located at the front end of the buckle 1 and exposed to the anvil seat 3. During installation, the buckle 1 and the beak 2 are first connected to ensure that the connecting protrusion 11 enters the inside of the mounting hole 21. Since the connecting protrusion 11 and the mounting hole 21 are movably matched, the buckle 1 can be rotated relative to the beak 2, so that the beak 2 can be installed on the anvil seat 3.

[0022] The beak 2 has a step structure, and the mounting holes 21 are located on both sides of the step structure. The front end of the buckle 1 corresponds to the step structure, and after the beak 2 and the buckle 1 are connected, the outer sides of the beak 2 and the buckle 1 are in a flat and aligned state.

[0023] The rear of the eagle beak 2 is also provided with a plug-in column 22, which is inserted into the slot 31 of the anvil seat 3. The cross-section of the plug-in column 22 and the slot 31 is a cross-shaped structure. The plug-in column 22 is arranged axially. After the eagle beak 2 and the buckle 1 are assembled, the plug-in column 22 is matched with the socket, and the plug-in column 22 is inserted into the slot 31 axially, and the eagle beak 2 and the anvil seat 3 are connected.

[0024] The outer end surface of the anvil seat 3 is provided with a mounting groove 32, and the buckle 1 is embedded in the mounting groove 32 and the front end extends out of the anvil seat 3. The buckle 1 is snapped onto the anvil seat 3. At this time, the beak 2 and the anvil seat 3 are still not fastened, and the buckle 1 needs to be connected to the anvil seat 3, so as to achieve axial connection between the beak 2 and the anvil seat 3. The buckle 1 can be rotated relative to the beak 2, and the buckle 1 is rotated to embed the buckle 1 into the mounting groove 32 of the anvil seat 3 to complete the connection between the buckle 1 and the mounting groove 32, so that the buckle 1 can be used as an intermediate connecting piece to fix the beak 2 and the anvil seat 3, and the assembly can be completed quickly.

[0025] Since the inner side protrusion of the buckle 1 is engaged with the anvil seat 3, when it is necessary to remove the olecranon 2, it is only necessary to press the inner side of the buckle 1 to very conveniently separate the buckle 1 from the anvil seat 3, and then remove the olecranon 2. The above-mentioned disassembly and assembly structure is very convenient, which can reduce the time during the operation and ensure the smooth progress of the operation.

[0026] The above-mentioned anvil adopts an existing conventional structure and can be reasonably selected according to surgical needs. The specific structure of the anvil and the connection structure between the anvil and the stapler are not described in detail.

[0027] Different from the prior art, the detachable olecranon assembly of the anvil of the utility model can be individually disassembled and replaced according to needs, avoiding the need to replace the entire anvil structure during surgery. It has a simple structure, is easy to operate, and reduces surgery time.

[0028] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
