DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-6 A nerve recognition early warning electric knife comprises a knife handle 1 and a voltage regulating mechanism, wherein an electric knife head 2 and a drainage tube 5 are arranged at the front end of the knife handle 1, a groove 3 is provided on the knife handle 1, and a control button 4 is provided on the inner wall of the groove 3, a first air bag 6 is provided on the side of the front end outer wall of the drainage tube 5 away from the electric knife head 2, a current releaser 8 is fixedly provided on the outer wall of the first air bag 6, a second air bag 7 corresponding to each other is also provided on the front end outer wall of the drainage tube 5, a pressure sensor 9 is fixedly provided on the outer wall of the second air bag 7, the first air bag 6 and the second air bag 7 are both connected to one end of a connecting tube 10, the connecting tube 10 passes through the drainage tube 5 and is connected to the voltage regulating mechanism, a motor 15 is fixedly provided on the outer wall of the knife handle 1, and a current releaser 8 is fixedly provided on the output shaft of the motor 15 A rotating rod 16 is provided, and the rotating rod 16 is perpendicular to the output shaft of the motor 15. A laser rangefinder 17 is installed at the end of the rotating rod 16. An indicator light 18 is fixedly provided on the outer wall of the motor 15 housing. The pressure regulating mechanism includes an annular groove 13 opened at the rear end of the shank 1, and the annular groove 13 is connected to one end of the connecting pipe 10. An annular piston 12 is inserted in the annular groove 13, and a sleeve 11 is sleeved on the outer side of the annular piston 12. The end of the sleeve 11 is fixedly connected to the annular piston 12 through a fixing plate. A thread is provided on the inner wall of the sleeve 11, and the sleeve 11 is threadedly connected to the rear end of the shank 1. A single-chip microcomputer is installed inside the shank 1, and the single-chip microcomputer is connected to the current releaser 8, the pressure sensor 9, the laser rangefinder 17 and the indicator light 18 through a signal cable.

[0023] Furthermore, the outer wall of the sleeve 11 is wrapped with an anti-slip rubber layer.

[0024] Furthermore, the current of the current releaser 8 is 0.1-30 mA.

[0025] Furthermore, it also includes a protection tube 14, through which the drainage tube 5 and the power line connected to the knife handle 1 pass. The protection tube 14 can protect the drainage tube 5 and the power line connected to the knife handle 1.

[0026] Furthermore, the laser rangefinder 17 is tilted, and the tilt angle of the laser rangefinder 17 is 10°-30°.

[0027] Furthermore, the laser rangefinder 17 faces the front end of the shank 1 .

[0028] Furthermore, the handle 1 is provided with an anti-slip portion, and the anti-slip portion is sleeved with a rubber anti-slip sleeve.

[0029] In this embodiment, when the device is used, after the electric knife head 2 is inserted into the wound, the pressure regulating mechanism is adjusted. The specific adjustment process is: rotating the sleeve 11, so that the annular piston 12 is inserted into the annular groove 13, and then the gas in the annular groove 13 is pressed into the first airbag 6 and the second airbag 7 through the connecting tube 10, so that the first airbag 6 and the second airbag 7 are expanded. At this time, the current releaser 8 and the pressure sensor 9 can be easily contacted with the tissue, and the first airbag 6 and the second airbag 7 have a certain elasticity to avoid secondary damage to the tissue, and then the motor 15 is rotated to excite the The optical rangefinder 17 is aimed at the normal tissue outside the wound, and the electric knife head 2 is slowly moved. When the distance measured by the laser rangefinder 17 changes greatly (greater than 0.5cm-2cm), the current releaser 6 discharges and releases a weak current. When there are nerves near the electric knife head 2, the muscles will tremble, the pressure sensor 9 will be compressed, and the indicator light will light up 18. When there are no nerves near the electric knife head 2, the muscles will not tremble or will tremble slightly, the pressure sensor 9 will not be compressed, and the indicator light will not light up, which will prompt the operator and facilitate the operator's operation.

[0030] The current releaser 8 and the pressure sensor 9 are installed on the airbag, so that after the electric knife head 2 makes a smaller incision, the drainage tube 5 can be inserted. The small incision of the wound is beneficial to the patient's recovery. After the drainage tube 5 is inserted, the airbag is inflated. At this time, the first airbag 6 and the second airbag 7 expand, and the current releaser 8 and the pressure sensor 9 can work normally.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
