Description
Technical field
The present invention relates to a kind of scalpel, specifically a kind of electronic rotary-cut safe operating knife, belong to medical instruments field.
Background technology
Scalpel is equipment more commonly used in surgical operation, is mainly used in cutting illing skin tissue.Conventional at present
Scalpel structure is that knife blade is arranged on handle of a knife, and applying the hand-held handle of a knife of patient can operate, but in practical operation use
It was found that there is a series of problems in this scalpel：First, knife blade is directly exposed to outer, is applied patient and is easy to be accidentally injured；Its
Secondary, because skin histology has certain hardness and toughness, using such routine operation knife, in incised tissue, precision is very
Difference, it is even more very difficult to be especially intended to position the skin incision for cutting out certain size, therefore for the skill requirement of operator
It is very high；It is very not round and smooth in addition, the knife-edge cut is uneven, be unfavorable for the quick healing of postoperative skin, to doctor and
Patient brings very big psychological burden.
The content of the invention
In view of the above-mentioned problems of the prior art, it is an object of the invention to provide it is a kind of it is safe to use, being capable of quick essence
Cut skin or other tough and tensile tissues accurately, the edge of a knife that can ensure to cut it is round and smooth it is regular, beneficial to postoperation recovery, so as to mitigate doctor
Suffer from the electronic rotary-cut safe operating knife of psychological burden.
To achieve the above object, the technical solution adopted by the present invention is：A kind of electronic rotary-cut safe operating knife, including handle
Portion and include circular knife and protective cover installed in the cutter head portion of handle portion front end, the cutter head portion, the circular knife passes through fastening
Bolt is fixed on the end of a rotating shaft, and the output shaft of the other end of rotating shaft and a motor is linked together, and the motor is arranged on
In the accommodating cavity of handle portion；The protective cover is arranged on accommodating cavity front end and covers circular knife.
The protective cover of the present invention covers circular knife to avoid surprisingly hurting sb.'s feelings, as the present invention's in the form of being covered using half
One preferable scheme, the protective cover is cylindrical shape, and the cover body front end side of protective cover is pressed flat, the side of circular knife
The groove of blade correspondence position from pressed flat stretches out.When cutting tissue, handle portion is held, circular knife is cut skin, now
Pressed flat is attached to skin surface, can avoid cutting too deep；In addition the hand that operator holds handle portion has stable impetus,
Cut direction is more conducively controlled, finally cuts out the edge of a knife of depth desired and length.
Further, in addition to an active lock pivot pin, the active lock pivot pin passes through accommodating chamber outer wall and deep from outside
Enter in accommodating cavity, the rotating shaft is provided with the pin shaft hole being engaged with active lock pivot pin.Active lock pivot pin is set effectively to keep away
Any rotation of rotating shaft, facilitates the demolition and maintenance of device when free of demolition.
Motor directly can be powered by external power source, it is preferred that in order to increase portability, the motor is supplied by battery
Electricity, battery are located in accommodating cavity, and anode is connected by the positive pole of power switch and motor, and the negative pole of motor is connected to
The negative pole of battery, the power switch are located at accommodating housing surface.
Preferably, the battery is rechargeable battery, and battery is by housing the charging inlet and outside that cavity rear end is set
Charger connects.
Preferably, the edge of a knife path that observation is cut when operating for convenience, the protective cover are made up of transparent plastic.Due to
The edge of a knife situation of incision can be understood at any time by transparent protective cover, further increase the precise degrees of operation.
Preferably, the motor is variable speed electric motors, particularly.Rotary circle can be changed simultaneously by changing the rotary speed of variable speed electric motors, particularly
The velocity of rotation of shape blade, so as to adaptability adjustment to cut the skin histology of different hardness and toughness.
Preferably, the other end of the rotating shaft is connected together by the output shaft of shaft coupling and motor.
During operation, circular shear blade is driven by motor to be rotated at a high speed, and blade is protected with protective cover, protects operator not
Accidentally injured by blade；Operator blade need to only be applied light and handy pressure can easily incised tissue, can also therefore will be more
Notice be absorbed in adjustment and grasp blade direction, so as to improve cut skin histology precision, it is easy to control
Cut skin depth and knife edge length；Due to using the adjustable rotary circular blade of rotating speed so that knife-edge is more flat
It is sliding, avoid the edge of a knife from being in the presence of uneven.
The present invention is easy to use, and blade need to only be placed in the tissue surface that will be cut open by operator, you can light and handy, accurate
Really, rapidly incised tissue, realization are precisely controlled incision size, cut out the round and smooth regular edge of a knife, and actual use confirms that its is obvious
The efficiency and surgical quality of operation are improved, it is more exquisite compared with coventional scalpel, and more light safety is operated, significantly reduce
Doctor and the psychological burden of patient.
