The pressing plate is connected and by blade pressing on tool apron with tool apron；A protective plate is additionally provided between the blade and pressing plate, it is described
The side opposite with the blade of blade extends outward to form comb teeth on protective plate, and side of the blade beyond protective plate is simultaneously located at
Below comb teeth.
As further improvement to above-mentioned technical proposal, the length of the comb teeth is 1.0mm-3.0mm, the blade end
Holding the distance apart from comb teeth end is 0.5mm-2.0mm.
As further improvement to above-mentioned technical proposal, distance of the blade end apart from comb teeth end is 1.0mm.
As further improvement to above-mentioned technical proposal, the upper surface of the tool apron is equipped at least two vertical limits
Column is equipped with limit hole corresponding with limited post on the protective plate and blade, and the limited post penetrates limit hole.
As further improvement to above-mentioned technical proposal, the quantity of the limited post is two and is symmetrical arranged.
As further improvement to above-mentioned technical proposal, the limited post and tool apron are integrally formed.
As further improvement to above-mentioned technical proposal, the lower surface of the pressing plate is equipped with a vertical screw rod, described
Connecting hole corresponding with screw rod is equipped on protective plate and blade, the tool apron and handle are equipped with screw hole corresponding with screw rod,
The screw rod is threadedly coupled after passing through connecting hole with screw hole.
As further improvement to above-mentioned technical proposal, the outer surface of the handle is equipped with non-slip texture flexible.
By above disclosure, the utility model has following advantageous effects:
The safety-type preparation skin knife of the utility model, due to being provided with protective plate, the side of protective plate between blade and pressing plate
Along comb teeth is extended outward to form, the blade of blade beyond the side of protective plate and is located at below comb teeth, thus conventional in use,
Comb teeth has been isolated blade and patient skin, and comb teeth is directly contacted with patient skin when use, and blade then will not be with patient skin
It directly contacts, injured patient's skin can be effectively prevent, improved the safety of use；In addition, passing through clinical operation doctor's
Practical operation empirical evidence, the part hair not struck off will not influence the operation such as surgical instrument and suture, mesh sheet, the utility model
The advantages outweigh the disadvantages, is conducive to promote and apply in medical field, has the effect of positive, meet society need, with stronger reality
The property used.
