At this time, the staff can align the two U-shaped clamps 13 with the tissue part that needs to be cut and stapled, and then stop applying pressure to the clamping assembly. After the clamping assembly loses strength, the spring 1 automatically rebounds and drives the first connecting rod 11 and the second connecting rod 12 to move closer again. The two U-shaped clamps 13 move closer to each other and clamp and fix the tissue part that needs to be cut and stapled. Finally, the staff can use the clamping of the two U-shaped clamps 13 to cut and staple the patient's tissue. In this step, the U-shaped clamp 13 is set to clamp the patient's component part to help better position the laparoscopic linear cutting stapler. The clamping force is kept constant by the spring 1, the first connecting rod 11 and the second connecting rod 12 to avoid additional damage to the patient's component, which is beneficial to improving the accuracy of the laparoscopic linear cutting stapler and reducing additional damage to the patient.

[0022] The protective component includes a medical plastic clip 2, on the side wall of which multiple groups of buckles 21 are fixed, and each two corresponding buckles 21 form a group. The side wall of the U-shaped clamp 13 corresponds to the multiple groups of buckles 21 and is provided with a slot 22.

[0023] The medical plastic clip 2 is fixed to the opposite sides of the two U-shaped clamps 13 by means of the buckle 21 and the slot 22, thereby replacing the opposite sides of the two U-shaped clamps 13. With the help of the patient's diseased tissue, the staff can replace the medical plastic clip 2 according to the tissue characteristics of the patient's diseased tissue to adapt to the tissue characteristics. This step protects the patient's diseased tissue by setting the medical plastic clip 2, avoids direct contact of hard components with the patient's tissue, and is beneficial to protecting the patient's diseased tissue and reducing secondary injuries.

[0024] Wherein, the clamping assembly includes a first movable rod 3, a fixed shaft 32 is fixedly connected to the side wall of the first movable rod 3, the fixed shaft 32 is rotatably connected to the second movable rod 31, and the second movable rod 31 is arranged parallel to the first movable rod 3, and the end of the second movable rod 31 away from the spring 1 is fixedly connected to an additional rod 33.

[0025] By applying a gripping force to the second movable rod 31 and the fixed shaft 32, the two U-shaped clamps 13 are moved away from each other, thereby clamping the patient's tissue part, and the fixed shaft 32 is close to the setting position of the spring 1 to increase the torque. In this step, by setting the first movable rod 3 and the second movable rod 31, a force is applied to the spring 1 to control the relative position of the two U-shaped clamps 13, thereby avoiding the problem that the spring 1 is not easy to deform, which is beneficial for the staff to control the accuracy of the position of the U-shaped clamp 13.

[0026] Among them, the limiting assembly includes a limiting block 4, which is fixed to the side wall of the first movable rod 3, and a buffer gasket 41 is provided at the top of the second movable rod 31 corresponding to the limiting block 4, and the buffer gasket 41 is connected to the second movable rod 31 through two plastic screws 42.

[0027] The limit block 4 fixedly connected to the top of the first movable rod 3 first contacts the buffer gasket 41 fixedly connected to the top of the second movable rod 31, and the two are squeezed against each other to limit the angle between the first movable rod 3 and the second movable rod 31. The staff can open the plastic screw 42 to replace or clean the buffer gasket 41 to ensure the safe operation of the limit block 4. This step limits the angle between the first movable rod 3 and the second movable rod 31 by setting the limit block 4 and the buffer gasket 41 to prevent the spring 1 from detaching from between the first movable rod 3 and the second movable rod 31, thereby ensuring the normal operation of the spring 1 and improving the stability of the device.

[0028] The fixing assembly includes a medical plastic sleeve 5 , a fixing block 51 is fixedly connected to the outer side of the medical plastic sleeve 5 , and two fixing blocks 51 are fixedly connected to the inner side walls of the first movable rod 3 and the second movable rod 31 , respectively.

[0029] The medical plastic sleeve 5 and the fixed block 51 are used to bear the force of the first movable rod 3 and the second movable rod 31, and the force is transmitted to the spring 1, so that the two U-shaped clamps 13 are finally moved away from each other. The fixing assembly is fixed by means of the fixing block 51 and the clamping assembly, and the first connecting rod 11 and the second connecting rod 12 are protected by means of the medical plastic sleeve 5. In this step, the first connecting rod 11 and the second connecting rod 12 are fixed by setting the fixing block 51, and the first connecting rod 11 and the second connecting rod 12 are protected by means of the medical plastic sleeve 5, which is beneficial to reduce the deformation of the first connecting rod 11 and the second connecting rod 12 and extend the accuracy and service life of the device.

[0030] A medical plastic ring 6 is fixedly connected to the outer wall of the first connecting rod 11 , and a medical plastic ring 6 is fixedly connected to the outer wall of the second connecting rod 12 .

[0031] The two medical plastic rings 6 are used to apply a force to the first connecting rod 11 and the second connecting rod 12, so that the two U-shaped clamps 13 move away from each other. After the two U-shaped clamps 13 move away from each other, the first connecting rod 11 and the second connecting rod 12 near the spring 1 move closer to each other. At this time, the staff can take out the spring 1 from between the first movable rod 3 and the second movable rod 31 and replace it. In this step, the two medical plastic rings 6 are provided to facilitate the staff to take out the spring 1, avoid the scenario where the spring 1 is difficult to replace after being damaged, and facilitate the long-term and effective operation of the device.

[0032] The anti-skid assembly includes a hollow rod 7 , and an anti-skid sleeve 71 is fixedly connected to the outer wall of the hollow rod 7 .

[0033] The hollow rod 7 is used to apply gripping force to the first movable rod 3 and the second movable rod 31, and the two anti-slip sleeves 71 increase friction force by means of their own surface texture. This step prevents the device from slipping by providing the hollow rod 7 and the anti-slip sleeves 71, which is beneficial to improving the clamping accuracy of the device.

[0034] The working principle and use process of the present invention:

[0035] The clamping assembly transmits the force to the spring 1 by squeezing the fixing assembly. As the spring 1 is stressed, the first connecting rod 11 and the second connecting rod 12 are affected by the force and move away from each other. After the first connecting rod 11 and the second connecting rod 12 move away from each other, the two U-shaped clamps 13 move away from each other. At this time, the staff can align the two U-shaped clamps 13 with the tissue part that needs to be cut with the stapler, and then stop applying pressure to the clamping assembly. After the clamping assembly loses its force, the spring 1 automatically rebounds and drives the first connecting rod 11 and the second connecting rod 12 to move closer again. The two U-shaped clamps 13 move closer to each other and clamp and fix the tissue part that needs to be cut with the stapler. Finally, the staff can use the clamping of the two U-shaped clamps 13 to The patient's tissue is cut and anastomosed, and the medical plastic clip 2 fixes itself on the opposite sides of the two U-shaped clamps 13 through the buckle 21 and the slot 22, thereby replacing the opposite sides of the two U-shaped clamps 13. With the help of the patient's diseased tissue, the staff can replace the medical plastic clip 2 according to the tissue characteristics of the patient's lesions, so as to adapt to the tissue characteristics. The staff can apply a gripping force to the second movable rod 31 and the fixed shaft 32 to move the two U-shaped clamps 13 away from each other, and then clamp the patient's tissue part, with the help of the fixed shaft 32 approaching the setting position of the spring 1, increasing the torque, and when the angle between the first movable rod 3 and the second movable rod 31 is too large, it is easy to cause the spring 1 to fall off. Whenever the first movable rod 3 and the second movable rod 31 are aligned, the spring 1 will fall off easily. The angle between the two movable rods 31 is too large, and the limit block 4 fixedly connected to the top of the first movable rod 3 first contacts the buffer gasket 41 fixedly connected to the top of the second movable rod 31, and the two are squeezed against each other to limit the angle between the first movable rod 3 and the second movable rod 31. The staff can open the plastic screw 42 to replace or clean the buffer gasket 41, thereby ensuring the safe operation of the limit block 4. The medical plastic sleeve 5 and the fixing block 51 receive the force between the first movable rod 3 and the second movable rod 31, and transmit the force to the spring 1, so as to finally make the two U-shaped clamps 13 move away from each other. The fixing assembly is fixed to the clamping assembly with the help of the fixing block 51, and the first connecting rod 11 and the second connecting rod 12 are fixed with the help of the medical plastic sleeve 5. A medical plastic ring 6 is fixedly connected to the outer wall of the first connecting rod 11 for protection, and a medical plastic ring 6 is fixedly connected to the outer wall of the second connecting rod 12. During operation, the staff can use the two medical plastic rings 6 to apply a force to the first connecting rod 11 and the second connecting rod 12 to move the two U-shaped clamps 13 away from each other. After the two U-shaped clamps 13 move away from each other, the first connecting rod 11 and the second connecting rod 12 are close to the spring 1. At this time, the staff can take out the spring 1 from between the first movable rod 3 and the second movable rod 31 and replace it. The staff can use the hollow rod 7 to apply a grip to the first movable rod 3 and the second movable rod 31, and the two anti-slip sleeves 71 increase the friction force with the help of their own surface texture.
