DETAILED DESCRIPTION
[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0022] like Figure 1As shown, a stapler anvil that is easy to replace includes a stapler body 1 and a mounting assembly 3, a joint head 2 is mounted on the left end of the stapler body 1, a stapler magazine 4 is arranged below the stapler anvil body 304, and a stapler magazine seat 5 is mounted inside the stapler magazine 4, a limit block 6 is mounted on the left end of the stapler magazine 4, and the limit block 6 is arranged in three groups, a rotating knob 7 is mounted on the right end of the stapler body 1, and a device base 8 is mounted on the end of the rotating knob 7, a battery compartment 10 is mounted on the right end of the device base 8, and an anti-slip operating assembly 11 is arranged below the battery compartment 10, and the operating assembly 11 includes a hand A handle 1101 and an anti-skid pad 1102 are provided, and an anti-skid pad 1102 is installed in the middle of the handle 1101. The operation component 11 is provided to facilitate the operation of the device. The anti-skid pad 1102 is made of silicone material, which can increase the friction between the operator's hand and the stapler at the grip of the operator, thereby effectively avoiding slipping during use. A closing rod 12 is provided on the left side of the handle 1101, and a firing button 9 is provided on the left side of the closing rod 12. The anti-skid pad 1102 is made of silicone material, and the anti-skid pad 1102 and the handle 1101 are tightly connected.
[0023] like Figure 2 and Figure 3 As shown, a mounting assembly 3 for facilitating replacement of the anvil is arranged on the outer wall of the joint head 2, and the mounting assembly 3 comprises a connecting piece 301, a threaded hole 302, a fastening bolt 303 and an anvil body 304. A threaded hole 302 is provided at the upper end of the connecting piece 301, and a fastening bolt 303 is provided above the threaded hole 302, and an anvil body 304 is provided at the left end of the connecting piece 301. The installation assembly 3 is provided to facilitate replacement of the anvil. The threaded hole 302 and the fastening bolt 303 in the installation assembly 3 assemble and connect the connecting piece 301 to the joint head 2 by threaded connection. When the anvil is damaged, the connecting piece 301 and the anvil body 304 are disassembled, which can reduce waste of parts and thus reduce waste of resources.
[0024] In summary, the nail anvil that is easy to replace is first based on Figure 1-Figure 3In the structure shown in the figure, the operator holds the handle 1101, the battery compartment 10 can provide power for the stapler, and the anti-skid pad 1102 is made of silicone material, which can increase the friction between the operator's hand and the stapler at the handhold, thereby effectively avoiding slipping during use, enhancing the holding stability during convenient operation, and improving the stabilization effect during operation. Through the coordinated use of the operating handle 1101, the closing rod 12 and the firing button 9, the anvil body 304, the staple cartridge 4 and the staple cartridge seat 5 are overlapped, and the limit block 6 can limit the tissue so that the tissue cannot be separated from the staple cartridge seat 5 when clamped, thereby completing the closing of the device to achieve the anastomosis work. After the anvil is used, the anvil body 304 is prone to damage. By unscrewing the fastening bolt 303 from the threaded hole 302 and removing the connecting piece 301, the anvil can be replaced better, which can reduce the waste of parts and thus reduce the waste of resources.
