[0025] Example 1

[0026] like Figure 1-2 As shown, this embodiment proposes a non-stick surgical electric knife of tungsten-rhenium alloy, including a containing box 1, the interior of the containing box 1 is set as a cavity, a vertical gear 2 is fixedly connected to the interior of the cavity of the containing box 1, the vertical gear 2 rotates with the outer central gear 201, a protrusion 203 is sleeved on the outer side of the central gear 201, the bottom end of the protrusion 203 is pressed against the push rod 202, an arc groove is opened at the front end of the containing box 1, a slip ring 304 is fitted inside the arc groove of the containing box 1, a sliding block 303 is slidably connected inside the slip ring 304, the sliding block 303 is pushed to press against the protrusion 203, and then the central gear 201 is pushed to slide downward along the vertical gear 2.

[0027] In this embodiment, the push rod 202 sleeved on the outside of the protrusion 203 presses against the blade 6 at the bottom and slides downward. At this time, the blade 6 slides out from the inside of the cleaning pen cap 5. When the patient needs to be treated, the negative electrode plate 7 is attached to the patient's body, and the cutting button 301 is pressed to treat the patient.

[0028] Example 2

[0029] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the top end of the storage box 1 is fixedly connected with a connection socket 3, the bottom end of the storage box 1 is fixedly connected with a handle 4, the outer side of the handle 4 is provided with textures, the handle 4 is configured to be made of anti-slip material, the inside of the handle 4 is provided with a square groove, the inside of the square groove of the handle 4 is slidably connected with a blade 6, the top end of the blade 6 is fixedly connected with a push rod 202, the inside of the handle 4 is provided with a cavity, and the handle 4 is made of anti-slip material, which is more convenient during use, the top end of the blade 6 is configured to be a flat sheet, and the bottom end of the blade 6 is configured to be an arc-shaped blade portion and a rectangular blade portion, and the arc-shaped blade portion and the rectangular blade portion are integrally formed. The blade 6 slides out from the inside of the cleaning pen cap 5. When the patient needs to be treated, the negative plate 7 is attached to the patient's body, and the cutting button 301 is pressed. The top of the protective sticker 501 is attached with a fixing seat 601, and the inside of the fixing seat 601 is rotatably connected with a brush 602. The outer side of the brush 602 is rotatably connected to the blade 6. There are two groups of fixing seats 601 and brushes 602, and they are evenly arranged on both sides of the blade 6. The front end of the accommodating box 1 is fixedly connected with a hemostasis button 302, and the bottom end of the hemostasis button 302 is provided with a cutting button 301. At this time, the blade 6 reacts with the negative plate 7, and the current forms a closed loop. At this time, the electric knife can achieve cutting.

[0030] In this embodiment, the bottom end of the blade 6 is configured as an arc-shaped blade portion and a rectangular blade portion, and the arc-shaped blade portion and the rectangular blade portion are integrally formed, which is convenient for medical personnel to adjust the required cutting position without frequently turning the arm to adapt to incisions in different positions and directions, and impurities on the outside of the blade 6 are blocked by the square groove at the bottom end of the cleaning pen cap 5, so that the blade 6 is scraped clean, which is convenient for the next use of the blade 6.

[0031] The working principle of this utility model:

[0032] First, the staff member holds the outer side of the storage box 1 and holds the handle 4 with his hand. When the length of the blade 6 needs to be adjusted, the sliding block 303 inside the slip ring 304 is pressed and slid downward. At this time, the sliding block 303 presses against the internal protrusion 203 and slides downward. At this time, the protrusion 203 drives the central gear 201 fixed and welded on the outside to slide downward. At this time, the central gear 201 meshes with the vertical gear 2 on the outside and rotates downward. At this time, the push rod 202 sleeved on the outside of the protrusion 203 presses against the blade 6 at the bottom and slides downward. At this time, the blade 6 slides out from the inside of the cleaning pen cap 5. When it is necessary to treat the patient, the negative plate 7 is attached to the patient's body and the cutting button 301 is pressed. At this time, the blade 6 reacts with the negative plate 7, and the current forms a closed loop. At this time, the electric knife can achieve cutting, which is convenient for separating the lesion. When it is necessary to coagulate the blood clot, only the hemostasis button 302 needs to be pressed. At this time, the blood is coagulated, which is convenient for the operation of the lower part.

[0033] When the blade 6 is used for a long time, there is dirt and skin tissue on the outside of the blade 6. At this time, the sliding block 303 is pushed upward, and the sliding block 303 synchronously lifts the blade 6. At this time, the blade 6 passes through the inside of the cleaning pen cap 5. At this time, the fixing seat 601 at the top of the cleaning pen cap 5 drives the brush 602 on the outside to rub the blade 6, and then the blade 6 is scraped clean. At this time, the impurities on the outside of the blade 6 are blocked by the square groove at the bottom of the cleaning pen cap 5, and then the blade 6 is scraped clean, which is convenient for the next use of the blade 6.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
