[0002] The electrosurgical pen is an electrosurgical device that replaces mechanical scalpels for tissue cutting and is widely used in surgical operations. The electrosurgical pen generates a high-frequency high-voltage current at the end of the electrode to heat the body tissue when it comes into contact with the body, thereby separating and coagulating the body tissue, thereby achieving the purpose of cutting and hemostasis. It has the advantages of rapid hemostasis, less bleeding, prevention of bacterial infection, and good postoperative healing of patients. The existing electrosurgical pen consists of a power supply, a power cord, a handle, and an electrode connected to the handle. The electrode, the power cord, and the power plug are connected in sequence, and the electrode head is sheet-shaped.

[0003] During surgery, when the electrosurgical pen contacts the skin, a lot of heat is generated, thus generating smoke, which not only pollutes the environment, but also affects the health of patients and doctors.

[0031] Reference Figure 1 and Figure 2 According to the utility model, an anti-entanglement smoking electric knife pen includes a handle 100, a smoking assembly and an electric knife assembly. The handle 100 is provided with a smoking channel 101. The two ends of the handle 100 are respectively provided with a first opening 102 and a second opening 103 connected to the smoking channel 101. The inner wall of the smoking channel 101 is provided with an installation cavity 104. The two ends of the installation cavity 104 are respectively connected to the first opening 102 and the smoking channel 101; the smoking assembly includes a first smoking pipe 210, a second smoking pipe 220 and a connector 230. One end of the first smoking pipe 210 is installed in the second opening 103 and connected to the smoking channel 101. The other end is connected to the second smoking pipe 220 through the connector 230, and the second smoking pipe 220 is connected to a suction fan; the electric knife assembly includes an electrode 310, a control circuit board 320, and a power cord 330, the control circuit board 320 is arranged in the installation cavity 104, one end of the electrode 310 is electrically connected to the control circuit board 320, the other end of the electrode 310 extends out of the first opening 102, one end of the power cord 330 is electrically connected to the control circuit board 320, the other end of the power cord 330 extends into the first smoking pipe 210 and extends along the first smoking pipe 210 to the connector 230, the other end of the power cord 330 passes through the connector 230 and is connected to a power plug 340.

[0032] Specifically, when the anti-entanglement smoking electric knife pen provided by the embodiment of the utility model is in use, the doctor holds the handle 100 and controls the electrode 310 to generate current through the control circuit board 320, thereby cutting or stopping bleeding on the patient's body tissue, wherein the handle 100 is provided with a straight-through smoking channel 101, so that the smoke generated during the operation can be sucked away by the suction fan through the smoking pipe in time, which is conducive to the smooth progress of the operation and ensures the health of the doctor and the patient. By routing the power cord 330 along the first smoking pipe 210, the power cord 330 will not be entangled with the first smoking pipe 210, and the power cord 330 will not come into contact with the doctor's arm, which is convenient for the doctor to operate the handle 100, which is conducive to the smooth progress of the operation. On the other hand, the power cord 330 passing through the connector 230 can be fixed in position by the connector 230, reducing the possibility of the power cord 330 shaking left and right and causing entanglement, which is conducive to the smooth progress of the operation.

[0033] Reference Figure 3According to some embodiments of the present invention, the connector 230 has a first end 231 and a second end 232 that are connected to each other, the first smoking tube 210 is connected to the first end 231, the second smoking tube 220 is connected to the second end 232, the outer diameter of the first end 231 is smaller than the second end 232, one end of the power cord 330 is close to the outer wall of one side of the first end 231 and extends to the outside of the first smoking tube 210, and the first smoking tube 210 wraps the first end 231 and the power cord 330 at the same time.

[0034] Specifically, when the power cord 330 is in close contact with the outer wall of the first end portion 231, the sum of the diameter of the power cord 330 and the outer diameter of the first end portion 231 is smaller than the inner diameter of the first smoking tube 210, so that when the first smoking tube 210 wraps the first end portion 231 and the power cord 330 at the same time, the power cord 330 is forced to squeeze the first end portion 231, so that the two ends of the power cord 330 are respectively in close contact with the first end portion 231 and the first smoking tube 210, thereby firmly fixing the position of the power cord 330 and achieving a good sealing effect to prevent smoke from being discharged from the connection between the connector 230 and the power cord 330. Furthermore, in order to improve the sealing effect, in some embodiments, a sealing member can be provided at the connection between the connector 230 and the power cord 330 to improve the sealing effect.
