One of the cylinders is arranged in the moving hole of one of the dust-proof structures in a penetrating manner through the first moving groove, the circular hole is formed in the cylinder, the inner cavity of the circular hole forms the fixed cavity, one of the fixed rods is positioned in the fixed cavity, one of the operation parts is positioned at one end of the cylinder, and one of the clamping discs is positioned at one end, far away from the operation part, of the cylinder and abuts against the side wall of the tool holder at one side of the first moving groove; the other cylinder penetrates through the other moving hole of the dustproof structure through the second moving groove, the circular hole is formed in the cylinder, the inner cavity of the circular hole forms the fixed cavity, the other fixed rod is located in the fixed cavity, the other operation portion is located at one end of the cylinder, and the other clamping disc is located at one end, far away from the operation portion, of the cylinder and abuts against the side wall of the knife handle on one side of the second moving groove. When the scalpel is used, a user slides one of the operation parts with a hand, one of the operation parts drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, the friction line body groove increases the friction between the elastic adsorption film and the scalpel handle, the sticky layer sticks dirt on two sides of the scalpel handle, a plurality of condensed air flows are formed at the outer edge of the refrigerating layer, and the refrigerating layer is propped against the elastic adsorption film through the side wall of the protective layer, so that the two side walls of the scalpel handle can generate tiny water drops while the temperature of the two side walls of the scalpel handle is reduced by the plurality of condensed air flows, and when the stickiness of the sticky layer on the elastic adsorption film is reduced in long-time use of the scalpel, the elastic adsorption film can rub with the scalpel handle through the tiny water drops, thereby achieving the cleaning effect; because the refrigerating layer is arranged in the inner cavity of the protective layer, the protective layer plays a good protective effect on the refrigerating layer, even if the refrigerating layer is broken, refrigerating liquid in the refrigerating layer cannot flow onto the elastic adsorption film, and therefore smooth operation is guaranteed.
For example, in order to facilitate a doctor to switch scalpels of different specifications to scalpels of different specifications according to different wound sizes on an affected part during an operation, the minimally invasive scalpel further includes a second blade 60 and a third blade (not shown), and the second blade and the third blade are used for switching scalpels of different specifications to switch scalpels of different specifications according to different wound sizes on the affected part while cleaning two side walls of the scalpel handle by a user. It can be understood that the dimension of the blade is greater than the dimension of the second blade, the dimension of the second blade is greater than the dimension of the third blade, the second blade and the third blade are both located in the telescopic opening of the handle, the mounting openings (not shown) are respectively opened on the second blade and the third blade, the mounting opening on the second blade corresponds to the first moving groove, the second blade is inserted into the telescopic opening and extends to the first moving groove, at this time, one of the cylinders is sequentially inserted into the mounting opening on the second blade and the moving hole of one of the dust-proof structures through the first moving groove, the mounting opening on the third blade corresponds to the second moving groove, the third blade is inserted into the telescopic opening and extends to the second moving groove, the other cylinder is sequentially arranged in the mounting hole and the other moving hole of the dustproof structure on the third blade in a penetrating mode through the second moving groove, so that when the dustproof structures on two sides of the knife handle clean the two side walls of the knife handle, the scalpels of different specifications are switched to the scalpels of different specifications according to different wound sizes on affected parts. When the scalpel is used, a user slides one of the operation parts with a hand, one of the operation parts drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, the friction line body groove increases friction between the elastic adsorption film and the scalpel handle, the sticky layer adheres dirt on two sides of the scalpel handle, meanwhile, when the operation part drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, the second blade and the third blade stretch out and draw back after stretching, and therefore the user can switch scalpels of different specifications to switch scalpels of different specifications according to different wound sizes on an affected part.

When a user uses the minimally invasive scalpel, the user slides one of the operation parts with a hand, one of the operation parts drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, the friction line body groove increases the friction between the elastic adsorption film and the scalpel handle, the sticky layer sticks dirt on two sides of the scalpel handle, and a plurality of condensed air flows are formed at the outer edge of the refrigerating layer and are propped against the elastic adsorption film through the side wall of the protective layer, so that the two side walls of the scalpel handle can generate fine water drops while the temperature of the two side walls of the scalpel handle is reduced by the plurality of condensed air flows, and when the stickiness of the sticky layer on the elastic adsorption film is reduced after the scalpel is used for a long time, the elastic adsorption film can rub with the scalpel handle through the fine water drops, thereby achieving the cleaning effect; because the refrigerating layer is arranged in the inner cavity of the protective layer, the protective layer plays a good protective effect on the refrigerating layer, even if the refrigerating layer is broken, refrigerating liquid in the refrigerating layer cannot flow onto the elastic adsorption film, and therefore smooth operation is guaranteed.
When the minimally invasive scalpel is further used by a user, the user slides one of the operation parts with a hand, one of the operation parts drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, the friction line body groove increases the friction between the elastic adsorption film and the scalpel handle, the sticky layer adheres to dirt on two sides of the scalpel handle, meanwhile, the operation part drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, and the second blade and the third blade stretch back and forth after stretching, so that the user can switch the scalpels of different specifications to surgical scalpels of different specifications according to different wound sizes on an affected part.
When a user further uses the minimally invasive scalpel, when the operation portion drives the dustproof structure on the cylinder to slide back and forth in the first moving groove or the second moving groove, the first line body and the second line body drive the cylinder in the third moving groove to slide back and forth, so that the adhesive layers on the dust removal structures on two sides of the cylinder are driven to stick dirt on two sides of the fixing portion, the temperature of two side walls of the fixing portion is reduced by the plurality of condensed air flows, meanwhile, two side walls of the fixing portion can also generate fine water drops, even if the viscosity of the adhesive layer on the elastic adsorption film is reduced, the elastic adsorption film can rub with the fixing portion through the friction between the fine water drops, and therefore the cleaning effect is achieved.
The above examples only express embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
