Or unload that division operation is unskilled, easily lead to the situation of blade cutting user's both hands, occurs often in clinical position, cause patient
Sharp instrument incised injury there will be severe band blood blade cutting patient manipulator and cause infectious disease exposure etc., and being brought to patient need not
The damage wanted and pain.
Utility model content
The utility model is intended to provide a kind of dismountable scalpel, not easy damaged operator, avoids injury from sharp utensil, and solid
Ledger-plate impetus is clear, and fixed effect is good, and charge and discharge operations are easy.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of dismountable scalpel, including handle of a knife and disposable blade are provided with through-hole on the disposable blade, described
Handle of a knife includes preceding handle of a knife and rear handle of a knife, and preceding handle of a knife and rear handle of a knife one end are flexibly connected, and preceding handle of a knife and the rear handle of a knife other end pass through card
Button connection；Blade positioning plate is connected after described at the top of handle of a knife, the center of blade positioning plate inner surface is equipped with positioning column, described fixed
Position column is vertical with blade positioning plate, and blade positioning plate is parallel with handle of a knife；Inside after described at the top of handle of a knife is provided with blade fixing groove,
Inside at the top of preceding handle of a knife is equipped with blade fixed block, and the disposable blade passes through blade fixing groove, blade fixed block and positioning
Column is fixed on handle of a knife.
Preferably, the blade positioning plate inner surface is flushed with rear handle of a knife inner surface.
Preferably, the through-hole internal diameter is equal with positioning column outer diameter.
Preferably, the width of the disposable blade is 0.5cm, and through-hole internal diameter is 0.3cm.
Preferably, the disposable blade is parallel with handle of a knife.
Preferably, the edge of the handle of a knife and blade positioning plate carries out blunt processing.
Preferably, the flexible connection of the preceding handle of a knife and rear handle of a knife is hinge connection.
The scalpel of the utility model, using rotation fixing cutter slice structure and retractable double leaf blade structure, in use,
Disposable blade is mutually fitted by through-hole with the positioning column of knife handle head end, and rotation makes blade enter to after parallel with blade
In fixing groove, blade can be such that fixed block is acted on fixing groove, realize that the tail end of blade is fixed again by the clamping of front and back handle of a knife,
To realize that circular hole region in the middle part of blade and tail portion, the region for entering handle of a knife is double fixed, therefore it is errorless to can guarantee that blade is fixed；This
Utility model uses blade folding bi-lobate structure, double leaf blade can be lockked after closure, to fixed blade tail end, fixed effect
It is more preferably reliable, interim card slippage, injury from sharp utensil risk smaller.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 be preceding Knife handle structure schematic diagram,
Fig. 3 is rear Knife handle structure schematic diagram.
Fig. 4 is to implement illustration.
