The invention relates to a handheld assembly of an electric surgical instrument and the electric surgical instrument. The handheld assembly of the electric surgical instrument comprises a power assembly, a driving assembly, a switching assembly, a first power output assembly, a second power output assembly, a control circuit and a casing part, wherein the switching assembly comprises a shaft, a first gear, a second motor, a transmission rod and a switching meshing part; and the switching meshing part enables the switching assembly to be in a first output mode or a second output mode. The handheld assembly of the electric surgical instrument realizes swing rotation, occlusion and percussion of a screw bin assembly through a first motor with high power. The complexity of the structure of theelectric surgical instrument is reduced and the cost is saved. Meanwhile, the output modes are switched through a second motor with low power, and an insurance structure for preventing mis-percussionis formed by setting an initial driving state.

The invention belongs to the technical field of slope protection, and particularly relates to a hexagonal block slope protection brick, a slope protection assembly applying the same and a slope protection system. The lower part of one side surface of a block body of the hexagonal block slope protection brick protrudes outwards to form a lower protrusion, the upper part of the lower protrusion correspondingly forms an upper inserting groove, the lower part of the other side surface adjacent to the side surface is recessed inwards to enable the upper part of the side surface to form an upper eave, and the lower part, recessed inwards, below the upper eave correspondingly forms a lower inserting groove; the upper eave or the lower protrusion is arranged on the opposite surface of the side surface where the lower protrusion is located, and the lower protrusion or the upper eave is arranged on the opposite surface of the side surface where the upper eave is located; and the groove length directions of the lower inserting groove and the upper inserting groove extend in the side length direction of the side where the current inserting groove of a parallel hexagon is located. Every two adjacent hexagonal block slope protection bricks can be combined to form the slope protection assembly, and all the slope protection assemblies can be combined to form the slope protection system. According to the hexagonal block slope protection brick, the slope protection assembly applying the same and the slope protection system, through the cooperation between the hexagonal block slope protectionbricks, the anti-sinking, anti-warping, anti-sliding and anti-scouring functions of the hexagonal block slope protection brick, the slope protection assembly and even the whole slope protection system are realized.

The invention provides a nail cartridge for an intracavity cutting anastomat, and the nail cartridge for the intracavity cutting anastomat solves the technical problems of poor anastomosis effect, more bleeding and high surgery risk in the existing ail cartridge for the intracavity cutting anastomat; the nail cartridge for the intracavity cutting anastomat is provided with a nail cartridge body, the nail cartridge body is provided with a cutting slot and suture nail slots, the nail cartridge body is also provided with a first tissue contacting surface and a second tissue contacting surface, wherein the first tissue contacting surface is located in the middle of the nail cartridge body in transverse direction, the second tissue contacting surface is located on the outside of the first tissue contacting surface; the second tissue contacting surface is higher than the first tissue contacting surface by 0.35mm, the suture nail slots are arranged in the first tissue contacting surface and the second tissue contacting surface, and the nail cartridge for the intracavity cutting anastomat can be widely used for intracavity cutting anastomats.

The invention relates to a variable-section engine body stitching bolt structure. The variable-section engine body stitching bolt structure comprises a bolt locking sleeve, a variable-section screw, an upper crankcase and a lower crankcase. The bolt locking sleeve is provided with an inner hexagonal nut, a polished shaft assembled with the upper crankcase and a threaded blind hole. The variable-section screw is provided with an upper outer thread, a lower outer thread, a small-diameter polished rod, a large-diameter polished rod, clamping faces, transition arcs and transition fillets. A variable-section through hole is formed in the upper crankcase, and a threaded blind hole is formed in the lower crankcase. The variable-section screw is tightly screwed and assembled on the lower crankcase through a thread. The upper crankcase is installed on the lower crankcase so that the variable-section screw can be put in the through hole of the upper crankcase. The bolt locking sleeve is assembled in the through hole of the upper crankcase and is tightly screwed with the variable-section screw rod through a thread. By means of the variable-section engine body stitching bolt structure, reliability of an engine body can be obviously improved on the premise that structural arrangement of the engine body is met.
