Background technology
Existing fine steel needle, the pull needle for particularly penetrating big bone are long.Big bone (example is penetrated in fine steel needle
Such as：Arm bone or thigh bone) after, one part can be exposed at outside human body., it is necessary to which fine steel needle is taken out after fracture portions recovery.
Since a part of fine steel needle is exposed, causes to be contaminated thereon, when it is extracted out again, human body can be again passed through,
The needle body of pollution can cause wound infection, and disinfection becomes very complicated, also increases the pain of patient.China Patent No. for this
ZL201120026199.7, the document of entitled " Split skeletal traction pin " disclose a kind of split type fine steel needle.The bone
Pull needle is divided into two sections, they are connected together by screw thread, forms a complete fine steel needle.Needing to take out Bone traction
When pin, therefrom separated two sections of needle bodies can be extracted out from human body.Fine steel needle is exposed at the part outside human body, will not be again
Through human body.Therefore the needle construction can reduce wound infection as far as possible.
Due to very long in Bone traction process, needle body passes through human body for a long time, and needle body exposes the ground that human body parts have a common boundary with human body
Side is very easy to infection, it is therefore desirable to periodically disinfection, and carry out necessary wrapping protective treatment.Wrapping up safeguard procedures is typically
Wound circumference is wrapped in gauze and ethanol for disinfection.But alcohol is readily volatilized, cause Disinfection Effect not lasting, the time is somewhat long
A bit, effect is just deteriorated, and is easy to cause wound infection.So the gauze for often replacing wound is generally required, it is very cumbersome.And
Alcohol is excessively used, it is also possible to wound skin allergy can be caused, increase the pain of patient.
Utility model content
The utility model is directed to the problem of existing, there is provided a kind of electronic sterilization covering device of fine steel needle, in bone
Pull needle at wound in use, to sterilizing, to reduce wound from extraneous germ contamination.
The technical solution that the utility model is proposed with regard to above-mentioned technical problem is as follows：
A kind of electronic sterilization covering device of fine steel needle, it includes：For the inner sleeve being sleeved on fine steel needle and it is located at interior
Shell outside set；Inner sleeve is the pipe sleeve for having through hole, and circuit module is equipped between inner sleeve and shell；Circuit module includes substrate,
Substrate is set on the outside of inner sleeve, and ultraviolet LED lamp is equipped with substrate；Transparent panel is equipped with the surface of ultraviolet LED lamp, thoroughly
Bright panel is put in being set in.
Preferably：The transparent panel is collector lens.Collector lens can make ultraviolet light focus more on wound circumference.
Preferably：Reflector is equipped with the transparent panel outer sheath, the light of white is scribbled in the reflecting surface of reflector
Catalyst coating.Coating material is preferably the nano-titanium oxide photocatalyst material of white.White coating photocatalyst coating can be anti-
Ultraviolet is penetrated, and the ultraviolet that can be used without being mapped to wound is sterilized on coating, is formed in wound circumference low close
Bacterium environment is spent, further improves the microenvironment of wound circumference.
Preferably：Protrusion is equipped with the inside of the inner sleeve.Protrusion can be point-like or strip.

The beneficial effect brought of technical solution that the utility model embodiment provides is：
Compared with prior art, the article of the invention can be sleeved on fine steel needle, positioned at human body exposed portion.It is ultraviolet
The light direction of light faces wound direction, it can kill wound and neighbouring bacterium.Due to causing wound sense
The bacterium of dye both generally is from the air ambient outside human body, and the technology of the invention can form one in wound circumference
Isolated area, activated bacterial are not easy to access wound.On wound dressing after alcohol gauze, even if alcohol vapors away completely, effect
Ultraviolet light in gauze outer surface can farthest kill the various bacteriums to dissociate onto gauze, and then prevent bacterium from going deep into
Wound.With the killing to the bacterium near wound from ultraviolet light of the invention, timing or watt level control can be used
Mode carry out quantitative sterilization processing, to reduce infringement of the ultraviolet to human body.It can be reduced using the invention and hindered
Using the dosage for the chemicals sterilized at mouthful, it is new to avoid the problem that excessive chemicals infiltration human body causes.
