When the blade motor drives the winding roller 81 to rotate, the electrode needle 6 is movably arranged through the perforation 7 under the guiding action of the winding displacement cylinder 82. When the rotating plate 12 drives the winding roller 81 and the winding drum 82 to turn over, one end of the winding drum 82, which is far away from the winding roller 81, is always positioned in the installation drum 5.
After the electrode needles 6 are inserted into the tumor tissue to complete the high-temperature killing treatment of tumor cells, the tips of the electrode needles 6 are positioned at one side of the cutter head 2 far away from the hand-held part; the cutter head 2 is started to discharge and cut the tissue at the edge of the tumor tissue, and the electric knife is gradually moved along the cutting direction along with the cutting of the cutter head 2, so that the electric knife extends into the tissue. As the electric knife moves, the contact of the plurality of electrode needles 6 with the tumor tissue causes the rotation plate 12 to rotate within the mounting cylinder 5.
In order to avoid the diffusion of tumor cells caused when the cutter head 2 cuts the tissue which is not subjected to tumor ablation as far as possible, referring to fig. 2 and 3, a power-off assembly 13 for controlling the power-off of the cutter head 2 is arranged on the rotating plate 12, the power-off assembly 13 comprises a pressing block 131 fixedly arranged on the rotating plate 12 and a power-off contact 132 movably contacted with the pressing block 131, the pressing block 131 is fixedly arranged on the end face of the rotating plate 12, which is close to one side of the cutter head 2, and the pressing block 131 is arranged on one side of the rotating plate 12, which is far away from the perforation 7, the power-off contact 132 is arranged on the bottom wall in the mounting cylinder 5, and the power-off contact 132 is arranged on one side of the rotating shaft 20, which is far away from the perforation 7. The electrode needles 6 are inserted into tumor tissues, and the electrode needles 6 do not extend continuously any more along with the gradual extension of the electrotome cutter head 2 into the tissues, at the moment, the contact of the electrode needles 6 with the tumor tissues enables the rotating plate 12 to rotate in the mounting cylinder 5, one side of the rotating plate 12, which is close to the perforation 7, moves in a direction away from the cutter head 2, and one side of the rotating plate 12, which is far from the perforation 7, moves in a direction towards the cutter head 2; when the tool bit 2 of the electrotome is pushed by an operator to extend into the same height as the tip of the electrode needle 6, the rotating plate 12 is turned to the maximum angle, and the pressing block 131 and the power-off contact 132 are pressed at the moment, so that the discharge of the tool bit 2 is blocked, and the diffusion of tumor cells caused by continuous cutting of the tool bit 2 is effectively avoided.
In order to enable the rotating plate 12 to automatically reset after the electrode needle 6 is extracted from the tissue, referring to fig. 2 and 3, a reset piece 14 for driving the rotating plate 12 to reset is further arranged on the rotating plate 12, the reset piece 14 is specifically a tension spring, the tension spring is located on one side of the rotating plate 12 close to the through hole 7, one end of the tension spring is welded with the rotating plate 12, and the other end of the tension spring is welded with the inner bottom wall of the mounting cylinder 5. When the electrode needle 6 is pulled out of the tissue and wound into the mounting cylinder 5, the tension spring is recovered to be long, so that the rotating plate 12 is turned to an initial state, and the pressing block 131 is not contacted with the power-off contact 132 any more, so that the control key drives the cutter head 2 to cut in a discharging mode and the cutting is not blocked any more.

With the rotation of the rotating plate 12, the capillary tube is always in a relaxed state.
When the cutter head 2 discharges to cut tissues, the suction pump is started, negative pressure is formed on the side wall of the mounting cylinder 5 at the penetrating mounting position of the smoke suction pipe 151, so that a part of smoke generated by cutting the cutter head 2 is quickly sucked into the smoke suction pipe 151, and the purpose of quickly removing the smoke is achieved. Meanwhile, negative pressure is formed at the end of the winding displacement tube 82, one end of the winding displacement tube 82 far away from the perforation 7 can absorb the smoke of the other part, and one end of the winding displacement tube 82 close to the perforation 7 can absorb tissues, so that when the cutter head 2 is cut, the adsorption action of the winding displacement tube 82 and the tissues and the plug-in action of the electrode needle 6 and the tissues drive the rotating plate 12 to synchronously rotate along with the stretching of the cutter head 2, and when the cutter head 2 stretches into the same height as the tip of the electrode needle 6, the pressing block 131 is abutted with the power-off contact 132, and the cutter head 2 is controlled to stop cutting.
The implementation principle of the medical high-frequency electrotome provided by the embodiment of the application is as follows: when the tumor tissue is cut, the cutter head 2 is abutted against skin tissue at one side of the tumor tissue, then a forward button is pressed, the forward button drives the roller 81 to rotate through the power piece 83, so that three electrode needles 6 extend out of the perforation 7 under the guiding action of the wire arranging barrel 82 and are inserted into the tumor tissue from the edge of the tumor tissue, and when the tip of each electrode needle 6 is positioned at one side of the cutter head 2 far away from the handheld part, the roller 81 is stopped from being driven to rotate; then the electrode needle 6 is driven to discharge by the discharge button, so that the electrode needle 6 kills tumor cells at the edge of tumor tissue at high temperature.
After the ablation of the tumor cells is completed, the electrode needle 6 is stopped from being started to discharge, the cutter head 2 is driven to discharge by the control key, the cutter head 2 cuts the tissue at the edge of the tumor tissue, and meanwhile, the adsorption component is driven to start by the suction key; the smoke generated by cutting the cutter head 2 is sucked by the smoke sucking pipe 151 and the sucking pipe 153, and the edge of tumor tissue is sucked at the end part of the wire arranging barrel 82, so that the rotating plate 12 rotates in the mounting barrel 5 along with the cutting of the cutter head 2, and the tension spring is stretched; when the tool bit 2 of the electrotome moves to the same height as the tip of the electrode needle 6, the rotating plate 12 is turned to the maximum angle, at the moment, the tension spring stretches, the pressing block 131 is pressed with the power-off contact 132, so that the discharge of the tool bit 2 is blocked, at the moment, the tool bit 2 does not cut tissues any more, and the control key and the air suction key are released, so that the tool bit 2 is only abutted in the cut tissues.
Then the electrode needle 6 is pulled out from tumor tissues and wound in the mounting cylinder 5 by pressing the reverse button, and the rotating plate 12 is reset under the action of the tension spring; the electrode needle 6 is then reinserted into the tumour tissue, where the electrode needle 6 is inserted deeper than the first insertion.
