Has the advantages that: through rotating the bull stick, the bull stick rotates along with the bull stick is synchronous, because the blade has certain deformability, the situation of perk slightly upwards probably appears in the tool edge department of blade, and the flexible sheet roll-off this moment not only shelters from the blade of roll-off, also plays the effect of pressing the blade simultaneously.
Furthermore, one end of the rotating rod penetrates through the mounting seat, and a knob is fixed at one end of the rotating rod, which extends out of the mounting seat.
Has the advantages that: the knob is arranged to facilitate the medical staff to rotate the rotating rod, thereby adjusting the blade.
Further, the cross section of the upper gland is in an arc shape protruding upwards.
Has the advantages that: set up the gland into the arc and make, go up the gland and only both sides compress tightly on the blade, reduce the area of contact of gland and blade, make the blade easily slide.
Furthermore, the lower pressing plate is in a strip shape, and a plurality of comb teeth distributed at intervals are arranged on the side edge of the lower pressing plate in the length direction.
Has the advantages that: the comb teeth are arranged to prevent the blade from directly contacting the skin of a patient, so that potential safety hazards are increased.
Further, the handle of a knife is hollow structure, is equipped with the disinfection bag in the handle of a knife, and disinfection bag top intercommunication has the drain pipe.
Has the advantages that: through setting up disinfection bag and drain pipe, through the antiseptic solution direction broach department in the drain pipe will disinfect the bag to carry out disinfection treatment to patient's preserved skin department.
Further, a liquid outlet one-way valve is arranged on the liquid outlet pipe.
Has the advantages that: by arranging the valve, the phenomenon that external moisture or other pollutants enter the disinfection bag when the skin preparation knife is not used can be avoided.
Furthermore, a liquid guide groove is formed in the top surface of the mounting seat along the length direction of the lower pressing plate, and the liquid outlet pipe is communicated with the liquid guide groove.
Has the advantages that: the disinfectant discharged from the liquid outlet pipe firstly enters the liquid guide groove, slowly flows to the space between the comb teeth through the liquid guide groove, and then flows to the skin of a patient, so that the skin preparation part of the patient is disinfected.
