[0028] Two abutment blocks 16 are provided on the upper side of the movable plate 13, buttons 161 are fixed on the upper ends of the two abutment blocks 16, conductive sheets 17 are installed on the front and rear sides of the lower ends of the abutment blocks 16, the switch 15 is installed with electrode sheets 18 matching the conductive sheets 17, and a pressing spring 19 is provided between the lower side of the abutment blocks 16 and the shell 1.

[0029] The two buttons 161 are divided into an electric cutting button and an electric coagulation button; when the electric knife is in use, first the wire of the electric knife is connected to the high-frequency high-voltage current machine. During surgery, when surgical cutting is required, the electric cutting button is pressed, and the electric cutting button moves downward through the abutment block 16 to push the movable plate 13 downward. The downward force can be converted into a horizontal force through the hinge rod 14, so that the electric knife head 12 extends horizontally out of the shell 1. At the same time, the two conductive plates 17 at the bottom of the abutment block 16 are connected to the electrode plate 18 of the switch 15, so as to conduct the circuit between the electric knife head 12 and the high-frequency high-voltage current machine. , surgical cutting work can be carried out. After releasing the electrocuting button, the movable plate 13 is pushed upward and reset under the elastic force of the first spring 131, thereby driving the electric knife head 12 to retract into the shell 1, and the elastic force of the pressing spring 19 can push the abutment block 16 to move upward and reset; when coagulation is needed, press the electrocoagulation button. After the electrocoagulation button is pressed, the corresponding abutment block 16 moves downward, so that the corresponding electrode sheet 18 contacts the conductive sheet 17, and the circuit between the electric knife head 12 and the high-frequency high-voltage current machine is turned on. Similarly, the electric knife head 12 is extended again to carry out electrocoagulation work.

[0030] A blocking assembly is provided in the opening, which includes a receiving groove 2 provided on the lower side of the left end of the shell 1, a blocking block 21 is slidably provided in the receiving groove 2, a second spring 22 is provided between the lower side of the blocking block 2 and the bottom wall of the receiving groove 2, a transversely arranged strip shell 23 is fixed on the left side of the shell 1, a first gear 24 is rotatably installed in the strip shell 23, racks 25 meshing with the first gear 24 are slidably provided on the upper and lower sides of the strip shell 23, the left end of the upper rack 25 is connected to the blocking block 2 by a pull wire, and a push plate 26 is connected to the right end of the lower rack 25, the push plate 26 extends into the shell 1 and abuts against the slide plate 11, a third spring 27 is provided between the right side of the push plate 26 and the right wall of the strip shell 23, and the elastic force of the third spring 27 is greater than the elastic force of the second spring 22.

[0031] When the electric knife head 12 is located inside the housing 1, the elastic force of the second spring 22 pushes the blocking block 2 to move upward to block the opening, thereby preventing foreign matter from entering the housing 1;

[0032] When the electric knife head 12 extends out of the shell 1, the left end of the electric knife head 12 is a short distance away from the opening, and the slide plate 11 drives the electric knife head 12 to slide to the left horizontally. Since the elastic force of the third spring 27 is greater than the elastic force of the second spring 22, the elastic force of the third spring 27 will push the push plate 26 to move to the left, thereby driving the lower rack 26 to move to the left, and driving the upper rack 26 to move to the right through the first gear 24. The blocking block 2 is pulled downward into the storage groove 2 by the pull wire, and the opening of the shell 1 is opened. The electric knife head 12 continues to move to the left and can extend out of the shell 1 through the opening to work.

[0033] An air duct 3 is fixed at the bottom of the shell 1, the left end of the air duct 3 is located at the lower side of the opening, and the right end of the air duct 3 is connected to an external air pump through a hose; when performing surgery, the air pump continues to work to generate suction to remove odor during the operation.

[0034] A circular shell 31 is installed on the left side of the air guide pipe 3. The upper end of the circular shell 31 is connected to the inside of the housing 1 through the air pipe. A partition 32 is rotatably installed at the center of the circular shell 31. A second gear 33 meshing with the upper rack 25 is rotatably installed in the strip shell 23. The second gear 33 is transmission-connected to the partition 32.

[0035] A suction seat 34 is installed at the bottom of the shell 1 . The suction seat 34 is provided with a plurality of suction holes 341 . The suction holes 341 are communicated with the interior of the shell 1 .

[0036] During the operation, the electric knife head 12 extends out of the housing 1, and the partition 32 in the circular case 31 is in a horizontal state. The left end of the airway 3 is connected to the air pump, and the air pump can remove the odor during the operation.

[0037] After the operator releases the button 161, the electric knife head 12 is retracted into the housing 1, and the upper rack 26 slides in the strip housing 23, driving the second gear 33 to rotate, thereby causing the partition 32 to rotate. Figure 5 As shown, the partition 32 is in an inclined state, connecting the air duct 3 with the interior of the shell 1, so that the outside air will be sucked into the interior of the shell 1 through the plurality of suction holes 341, and then enter the air duct 3 from the air pipe and the circular shell 31. In this way, when the operator does not use the electric knife temporarily, the left end of the air duct 3 does not generate suction, and the suction is converted to the suction seat 34 on the lower side. The operator can place the electric knife on the table, and the suction generated by the suction seat 34 can prevent the electric knife from being pulled and falling.

[0038] Furthermore, the electric knife can be placed on a flat vertical surface, such as the side of the operating table or the side of the operating light support arm. The suction force generated by the suction seat 34 can adsorb the entire electric knife, so that the operator can easily place the electric knife in a convenient position during surgery.

[0039] A rubber ring is provided at the bottom of the suction seat 34 to increase the sealing performance between the suction seat 34 and the contact surface, making the electrosurgical knife adsorption more stable.

[0040] A tank body 4 is installed on the right side of the shell 1, a piston 41 is slidably provided in the tank body 4, a connecting rod 42 is connected to the left side of the piston block 41, a push block 43 is fixed to the end of the connecting rod 42, a bevel is processed on the lower side of the push block 43, a push rod 132 abutting against the side wall of the push block 43 is fixed to the movable plate 13, a fourth spring 44 is provided between the push block 43 and the tank body 4, a one-way liquid inlet is provided at the right end of the tank body 4, a liquid storage tank 45 is installed on the right side of the shell 1, the liquid storage tank 45 is connected to the one-way liquid inlet, a one-way liquid storage port is also provided on the right side of the tank body 4, a liquid spray port 46 is provided on the upper side of the left end of the shell 1, and the liquid spray port 46 is connected to the one-way liquid storage port through a liquid channel;

[0041] Disinfectant is stored in the liquid storage tank 45. When the button 161 is pressed downward to extend the electric knife head 12 out of the shell 1, the movable plate 13 moves downward, and the push rod 132 moves to the inclined surface of the push block 43. At this time, the push block 43 is pushed to move by the elastic force of the fourth spring 44, and the piston 41 is driven to move to the left by the connecting rod 42, generating suction to draw the disinfectant in the liquid storage tank 45 into the tank body 4. When the electric knife head 12 is retracted into the shell 1, the movable plate 13 moves upward, pushing the push block 43 to move rightward, and the piston 41 moves rightward in the tank body 4, pushing the disinfectant in the tank body 4 into the liquid spray port 46 for spraying. The disinfectant is then sprayed onto the surface of the electric knife head 12 for disinfection. Therefore, the electric knife head 12 can be initially disinfected each time it is used.

[0042] The liquid spray port 46 is provided by an atomizer, and the sprayed disinfectant can evenly cover the surface of the electric knife head 12;

[0043] At the same time, the air duct 3 is connected to the inside of the shell 1, and the outside air flows in the shell 1, which can quickly dry the disinfectant on the surface of the electric knife head 12.
