[0025] Among them, the limit assembly 200 is installed on the handle 110 of the stapler body 100. When the medical staff presses the firing handle 150, the firing handle 150 can be restricted and fixed through the limit assembly 200, thereby reducing the possibility that the medical staff may experience discomfort in their hands under long-term pressing and be unable to continue pressing the firing handle 150.

[0026] See also Figure 1-Figure 2 A handle 110 is connected to one end of the stapler body 100, an adjusting nut 120 is rotatably installed on one end of the handle 110, a stapler cartridge housing 130 is connected to the other end of the stapler body 100, a stapler support 140 is connected to one end of the stapler cartridge housing 130, and a firing handle 150 is rotatably installed in the stapler body 100.

[0027] In this embodiment, a transparent protective cover 141 is connected to the surface of the anvil 140, and a light bar 142 is installed in the transparent protective cover 141. In specific implementation, the light bar 142 can be used to illuminate the patient's body at multiple angles, which is beneficial for medical staff to have a comprehensive understanding of the patient's internal conditions, thereby making the operation smoother. The light bar 142 can be protected by the transparent protective cover 141, and the light can be avoided from being blocked; a first anti-slip pad 111 is connected to the surface of the handle 110, and a second anti-slip pad 151 is provided on the surface of the firing handle 150. In specific implementation, the first anti-slip pad 111 is provided on the handle 110, and the second anti-slip pad 151 is provided on the firing handle 150, so as to reduce the possibility of the anorectal stapler falling off from the hands of medical staff. It should be noted that the first anti-slip pad 111 and the second anti-slip pad 151 can be made of rubber or silicone.

[0028] See also Figure 1-Figure 4 The limit assembly 200 includes a fixed seat 210 and a plug-in component 220. The fixed seat 210 is mounted on the surface of the handle 110. The plug-in component 220 is slidably arranged in the fixed seat 210. A spring 230 is arranged in the fixed seat 210. The spring 230 is connected to one end of the plug-in component 220. The surface of the firing handle 150 is connected to a card strip 160. A slot 240 corresponding to the card strip 160 is opened on the surface of the fixed seat 210. The plug-in component 220 runs through the card strip 160. In a specific implementation, When the staff holds the handle 110, pulls the connector 220, manually presses the firing handle 150, and inserts the clamping strip 160 into the slot 240 of the fixing seat 210. At this time, the connector 220 can be reset and inserted into the clamping strip 160 through the elastic force of the spring 230, thereby restricting and fixing the clamping strip 160 and the firing handle 150, thereby reducing the possibility that the medical staff may experience discomfort in their hands under long-term pressing and be unable to continue pressing the firing handle 150.

[0029] In this embodiment, a cavity 211 is provided in the fixing seat 210, and the spring 230 is located in the cavity 211. One end of the plug-in component 220 is in contact with the inner wall of the cavity 211. In a specific implementation, the spring 230 and one end of the plug-in component 220 are arranged in the cavity 211, which is beneficial to protecting the spring 230 and the plug-in component 220 and reducing the possibility of the plug-in component 220 being pulled out of the fixing seat 210. The plug-in component 220 includes a rod body 221, a connecting block 222 and an inserting block 223. The rod body 221 and the connecting block 222 are both slidably arranged in the cavity 211, and the rod body 221 is respectively connected to the connecting block 222 and the inserting block 223, and the connecting block 222 is connected to the spring 230. Block 223 passes through the card strip 160. In a specific implementation, by pulling the rod body 221, it drives the connecting block 222 and the insert block 223 to move, the connecting block 222 will compress the spring 230, and the insert block 223 will be pulled out of the card strip 160, and the firing handle 150 will no longer be restricted. When the medical staff presses the firing handle 150, the card strip 160 will be inserted into the slot 240. The elastic force of the spring 230 can reset the rod body 221 and the connecting block 222, thereby driving the insert block 223 to be inserted into the card strip 160, thereby restricting the card strip 160 and reducing the possibility that the medical staff may experience discomfort in their hands under long-term pressing and cannot continue to press the firing handle 150.

[0030] A wear-resistant pad 250 is connected to the side of the connecting block 222, and the wear-resistant pad 250 fits against the inner wall of the cavity 211. In a specific implementation, the wear-resistant pad 250 is arranged on the side of the connecting block 222 to make the wear-resistant pad 250 fit against the inner wall of the cavity 211, thereby reducing the possibility of wear caused by the contact between the connecting block 222 and the inner wall of the cavity 211. It should be noted that the wear-resistant pad 250 can be made of rubber or silicone material; the upper end of the clamping strip 160 is set as an inclined surface, and the lower end of the plug block 223 is set as an inclined surface. In a specific implementation, the upper end of the clamping strip 160 and the lower end of the plug block 223 are set as inclined surfaces, so that the clamping strip 160 can be inserted into the slot 240 by pressing the firing handle 150; a pull block 260 is connected to one end of the rod body 221, and the pull block 260 is located outside the fixing seat 210. In a specific implementation, the pull block 260 is pulled to facilitate the movement of the rod body 221.

[0031] Specifically, the working principle of the multi-angle lighting anorectal stapler is as follows: when in use, the light bar 142 on the anvil seat 140 is used to illuminate the patient's body from multiple angles, which is helpful for medical staff to understand the patient's internal conditions. By holding the handle 110 at one end of the stapler body 100 and pressing the firing handle 150, the card strip 160 is inserted into the slot 240 of the fixing seat 210, and the spring 230 in the cavity 211 drives the connecting block 222 to move. When the rod body 221 is reset, the insert block 223 will be inserted into the card strip 160, thereby restricting and fixing the card strip 160 and the firing handle 150, reducing the possibility that the medical staff may experience discomfort in their hands under long-term pressing and be unable to continue pressing the firing handle 150. By pulling the pull block 260, the rod body 221 drives the connecting block 222 to move, and the insert block 223 will be pulled out of the card strip 160, and the card strip 160 will no longer be restricted, making it easier for the firing handle 150 to move.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
