[0002] A surgical smoke knife, also known as a smoke-producing electric knife or an electric knife with an aspirator function, is a medical device widely used in surgical operations. This device combines the functions of a high-frequency scalpel and an aspirator, aiming to improve surgical efficiency, reduce intraoperative bleeding, maintain a clear surgical field of view, and protect medical staff from the hazards of surgical smoke. In the prior art, when a scalpel is used for clinical surgery, the surgical site structure is narrow and a large amount of smoke is generated, which obstructs the doctor's field of view during surgery and causes a series of problems such as long surgery time. In order to ensure a clear field of view during the operation, the doctor needs to use a smoke knife to absorb smoke, tissue debris, blood stains and other waste during the operation, and it can also flush the wound surface. During the manufacturing process of the smoking knife, the blade of the smoking knife needs to be assembled with the bellows through equipment. The blade of the smoking knife is connected to the bellows through a special-shaped tube, thereby ensuring the sealing between the blade and the bellows. At the same time, the bellows will not bend during the use of the smoking knife, resulting in the inability to discharge impurities such as smoke. In addition, the blade body of the smoking knife must also be assembled with the knife cap during the installation process, so as to strengthen the structure of the blade body and ensure the sealing of the blade body.

[0023] like Figure 1-Figure 2 As shown, a smoking knife blade assembly device includes an assembly platform 1, on which is provided a fixing seat 2 and a driving mechanism 3 arranged corresponding to the end of the fixing seat 2; the fixing seat 2 is formed with a connecting mounting groove 201 and an assembly groove 203, and a limiting groove 202 is formed at the connection between the mounting groove 201 and the assembly groove 203; the driving mechanism 3 includes a push rod 303 and a driving cylinder 301 for driving the push rod 303, and the push rod 303 is arranged corresponding to the assembly groove 203.

[0024] Furthermore, the fixing seat 2 and the driving mechanism 3 are arranged on the assembly platform 1 along the length direction of the assembly platform 1, the fixing seat 2 is located on the moving end of the driving mechanism 3, the blade cap 401 is sleeved on the blade body 4, the blade body 4 and the blade cap 401 are placed integrally in the fixing seat 2, specifically the blade body 4 is located in the installation groove 201 and the assembly groove 203, and the blade cap 401 is located in the limiting groove 202, and the limiting groove 202 is used to limit the blade cap 401, and the driving cylinder 301 controls the push rod 303 to push the blade body 4 to move, and then the blade cap 401 is assembled on the blade body 4, which improves the assembly efficiency and reduces the production cost. At the same time, the limiting groove 202 is used to limit the blade cap 401, ensuring that the blade cap 401 will not move during the movement of the blade body 4, thereby improving the assembly accuracy and ensuring the sealing of the blade body 4.

[0025] The mounting groove 201 and the assembly groove 203 are arranged along the length direction of the fixing seat 2, and the mounting groove 201 and the assembly groove 203 respectively pass through the opposite ends of the fixing seat 2. Furthermore, the mounting groove 201 and the assembly groove 203 are formed on the upper surface of the fixing seat 2, and the mounting groove 201, the assembly groove 203 and the positioning hole 501 are coaxially arranged. In addition, a positioning seat 5 is provided at the end of the fixing seat 2, and a positioning hole 501 connected to the assembly groove 203 is formed on the positioning seat 5. The positioning hole 501 is arranged along the thickness direction of the positioning seat 5, and the positioning hole 501 passes through the positioning seat 5. At the same time, the positioning hole 501 and the assembly groove 203 are coaxially arranged, which ensures the coaxiality of the positioning hole 501 and the assembly groove 203, thereby ensuring the accuracy of the push rod 303 when pushing the blade body 4 and the blade cap 401 for assembly.

[0026] The size of the limiting groove 202 is larger than the size of the installation groove 201, and the blade cap 401 is set in the limiting groove 202. Furthermore, the blade cap 401 is limited by the limiting groove 202. Specifically, the width of the limiting groove 202 is larger than the width of the installation groove 201. During the movement of the blade body 4, since the blade cap 401 is in the limiting groove 202, the blade cap 401 cannot move, thereby enabling the blade body 4 and the blade cap 401 to be assembled, and the assembly accuracy is guaranteed.

[0027] The radial dimension of the mounting groove 201 is smaller than the radial dimension of the assembly groove 203, and the mounting groove 201 is adapted to the end of the blade body 4. Furthermore, the mounting groove 201 is located on the end away from the driving mechanism 3, most of the main body of the blade body 4 is located in the assembly groove 203, and the end of the blade body 4 is located in the mounting groove 201. At the same time, the diameter of the end of the blade body 4 is smaller than the diameter of the main body of the blade body 4. When the blade body 4 moves, the moving position of the blade body 4 is restricted by the mounting groove 201, thereby avoiding excessive assembly of the blade body 4 and the blade cap 401, and further avoiding damage to the blade cap 401. In addition, the limiting groove 202 is arranged at the connection between the mounting groove 201 and the assembly groove 203, which is used to limit the movement of the blade cap 401, further ensuring the assembly quality of the blade body 4 and the blade cap 401.

[0028] The output end of the driving cylinder 301 is connected to the moving block 302, and the moving block 302 moves toward the fixed base 2. Furthermore, a clamping groove 3021 is formed on the moving block 302, and the end of the push rod 303 is provided with a clamping portion 3031 that is clamped with the clamping groove 3021. Specifically, the clamping groove 3021 is arranged on the side facing the fixed base 2, and the clamping groove 3021 is a T-shaped structure. The clamping portion 3031 at the end of the push rod 303 is a T-shaped block that is adapted to the clamping groove 3021. The T-shaped block is clamped in the clamping groove 3021, and the moving block 302 is driven to move by the driving cylinder 301, thereby driving the push rod 303 to move.

[0029] In addition, the push rod 303 is coaxially arranged with the positioning hole 501, and one end of the push rod 303 is located in the positioning hole 501, and one end of the push rod 303 is slidably connected to the positioning hole 501, and the push rod 303 is guided under the action of the positioning hole 501, thereby ensuring that the push rod 303 is always on the same axis as the assembly groove 203 during the movement process, ensuring the coaxiality of the blade body 4 and the blade cap 401 when the push rod 303 pushes the blade body 4 to move, thereby ensuring the assembly accuracy of the blade body 4 and the blade cap 401.
