[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0031] Example 1:

[0032] like Figure 1-Figure 5 As shown, a staple cartridge assembly rotation control and adjustment mechanism is provided inside the housing 4 of the electric laparoscopic stapler and is used to control the forward or reverse rotation of the staple cartridge assembly 5, and is characterized in that it includes:

[0033] The forward rotation switch 1 is located inside the housing 4 and is provided with a forward rotation contact 101. Pressing the forward rotation contact 101 can turn on the forward rotation switch 1, and the staple cartridge assembly 5 rotates forward.

[0034] The reversing switch 2 is located inside the housing 4 and is provided with a reversing contact 201. Pressing the reversing contact 201 can turn on the reversing switch 2, and the staple cartridge assembly 5 is reversed.

[0035] And a control mechanism 3, which includes an operating member 301 slidably set on the shell 4, a forward rotation link 302 connected to the operating member 301 and hinged to the shell 4, and a reverse rotation link 303 hinged to the shell 4, one end of the reverse rotation link 303 is a first pressing part 3031 for pressing the reverse rotation contact 201 to reverse the nail magazine assembly 5, and the other end is a driving part 3032, the forward rotation link 302 is provided with a second pressing part 3021 for pressing the forward rotation contact 101 to make the nail magazine assembly 5 forward, and a pressing part 3022 for pressing down the driving part 3032 to make the first pressing part 3031 press the reverse rotation contact 201.

[0036] When the operating member 301 is pushed upward, the operating member 301 drives the forward rotation link 302 to rotate clockwise around its hinge point, and the second pressing portion 3021 presses the forward rotation contact 101. At this time, the forward rotation switch 1 is turned on, and the staple cartridge assembly 5 rotates forward.

[0037] When the operating member 301 is pushed downward, the operating member 301 drives the forward rotation link 302 to rotate counterclockwise around its hinge point, and the pressing portion 3022 presses down the driving portion 3032 to make the reverse rotation link 303 rotate clockwise around its hinge point. The first pressing portion 3031 presses the reverse contact 201. At this time, the reverse switch 2 is turned on, and the nail magazine assembly 5 reverses.

[0038] In some examples, the forward rotation link 302 also includes a first link 3023, a second link 3024 and a third link 3025 connected end to end, which form a triangular structure, and the overall structure is more stable; the intersection of the first link 3023 and the second link 3024 is hinged to the shell 4, and the intersection of the first link 3023 and the third link 3025 is connected to the operating member 301, and the upper side of the intersection of the second link 3024 and the third link 3025 is provided with the above-mentioned second pressing portion 3021, and the lower side is provided with the above-mentioned pressing portion 3022.

[0039] In some examples, there are two operating members 301 and both are slidably arranged on both sides of the shell 4, one operating member 301 is connected to the forward rotation connecting rod 302, and the other operating member 301 is connected to the swing arm 304, and a connecting rod 305 is provided between the swing arm 304 and the forward rotation connecting rod 302; the operating members 301 on both sides are linked by the connecting rod 305, so that the surgeon can control the rotation of the nail magazine assembly 5 from both sides during the operation, thereby improving the convenience of operation.

[0040] In some examples, the operating member 301 includes a slider 3011 arranged on the outside of the shell 4 and an insertion rod 3012 extending into the shell 4 and connected to the forward rotation connecting rod 302. The forward rotation connecting rod 302 is provided with a socket for inserting the insertion rod 3012, and the shell 4 is provided with an arc-shaped groove for sliding the insertion rod 3012. The movement trajectory of the operating member 301 can be limited by the arc-shaped groove; the operator drives the insertion rod 3012 to move by pushing the operating member 301 located on the outside, and the insertion rod 3012 drives the forward rotation connecting rod 302 to rotate in a clockwise direction or a counterclockwise direction.

[0041] In some examples, the slider 3011 gradually bends outward from the middle to both sides, and the surface area of the slider 3011 gradually increases from the middle to both sides to form an "8" shape structure. When the operator's fingers push from the middle to both sides, the outward-bent sides can limit the fingers to prevent them from falling out during the pushing process.

[0042] In some examples, the insertion rod 3012 has two protrusions 3013 radially protruding from one end close to the slider 3011 , and the two are symmetrically arranged. The side of the forward rotation connecting rod 302 close to the operating member 301 is provided with a slot 3026 for inserting the protrusion 3013 .

[0043] In some examples, the shell 4 is provided with a limit block 401 for limiting the reversal link 303, and the limit block 401 is provided with a limit slope 4011. The upper side of the first pressing portion 3031 is an arc surface that cooperates with the reversal contact 201, and the lower side is a plane that cooperates with the limit slope 4011.

[0044] In some examples, the surface of the slider 3011 is formed with a plurality of anti-slip protrusions 3014 arranged at intervals to increase the friction between the operator's fingers and the slider 3011 to prevent the fingers from slipping.

[0045] Working principle:

[0046] When the operating member 301 is pushed upward, the operating member 301 drives the forward rotation link 302 to rotate clockwise around its hinge point, and the second pressing portion 3021 presses the forward rotation contact 101. At this time, the forward rotation switch 1 is turned on, and the staple cartridge assembly 5 rotates forward.

[0047] When the operating member 301 is pushed downward, the operating member 301 drives the forward rotation link 302 to rotate counterclockwise around its hinge point, and the pressing portion 3022 presses down the driving portion 3032 to make the reverse rotation link 303 rotate clockwise around its hinge point. The first pressing portion 3031 presses the reverse contact 201. At this time, the reverse switch 2 is turned on, and the nail magazine assembly 5 reverses.

[0048] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
