Skin is special to scrape instrument clearlyTechnical field
The present invention relates to a kind of medicine equipment, more particularly to a kind of skin is special scrapes instrument clearly.
Background technology
Clinically usually need to scrape focus clearly when carrying out skin diseases diagnoses and treatment to patient, existing operation is doctorBusiness personnel hold blade slow scraped finish, and in scale removal process, medical worker needs hand hanging for a long time, take during such operating costPower, also bad grasp, operation difficulty are big for dynamics sometimes.
The content of the invention
The present invention is for deficiency, there is provided a kind of skin simple to operate, easy to use is special to scrape instrument clearly.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of skin is special to scrape clearly instrument, including the link that left and right is correspondingly arranged, and link includes the centre that intermediate, inclined is setBar, it is characterised in that offer lift adjustment chute on intermediate bar along its length respectively, be total in the lift adjustment chute of left and rightLifting rotation locating rod is plugged with activity, and lifting rotation positioning is threaded with the lifting rotation locating rod on the outside of linkNut, lifting rotation locating rod are positioned in the lift adjustment chute of link intermediate bar by lifting rotation location nut, are risenDrop rotational positioning bar is fixedly connected with clear wing along its length；Correspondence is respectively fixedly connected between the link of left and rightThere is connecting plate, spring is fixedly connected with below connecting plate, lower spring end, which rotates against, is provided with roller.
Instrument is scraped according to described skin is special clearly, it is characterised in that the link is " Z " type, and the intermediate bar is located atThe middle part of link, the both ends of intermediate bar are connected to side pole, and it is corresponding that the connecting plate correspondence is fixedly connected on left and rightSide pole between.
Instrument is scraped according to described skin is special clearly, it is characterised in that is fixedly connected with multiple institutes below each connecting plateSpring is stated, each lower spring end rotates against the installation roller.
Instrument is scraped according to described skin is special clearly, it is characterised in that the lower spring end is fixedly connected with support, the rollingWheel is rotated against in support.
Instrument is scraped according to described skin is special clearly, it is characterised in that the support is the U-typed that Open Side Down.
The present invention is set clear wing is aerial, and hand-held connecting plate or link are gently pressed downwards during operation, behaviourMake simply, the hand of medical worker can be loosened, convenient to use beneficial to clear scraping operation.

Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, andIt is non-to be used to limit the scope of the present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of skin is special scrapes instrument, including the link that left and right is correspondingly arranged, link clearlyInclude the intermediate bar 9 of intermediate, inclined setting, lift adjustment chute 8, left and right liter are offered along its length respectively on intermediate bar 9Joint activity is plugged with lifting rotation locating rod 6 in falling tone section chute 8, screw thread in the lifting rotation locating rod 6 on the outside of linkLifting rotation location nut 7 is connected with, lifting rotation locating rod 6 is positioned among link by lifting rotation location nut 7In the lift adjustment chute 8 of bar 9, lifting rotation locating rod 6 is fixedly connected with clear wing 5 along its length；Left and right connectsCorrespondence has been respectively fixedly connected with connecting plate 4 between frame, and connecting plate 4 is fixedly connected with spring 3 below, and the lower end of spring 3 is relativeIt is rotatably installed with roller 1.
In the present embodiment, the link is " Z " type, and the intermediate bar 9 is located at the middle part of link, intermediate bar 9Both ends are connected to side pole 10, and the correspondence of connecting plate 4 is fixedly connected between side pole 10 corresponding to left and right.Each instituteState connecting plate 4 and be fixedly connected with multiple springs 3 below, each lower end of spring 3 rotates against the installation roller 1.It is describedThe lower end of spring 3 is fixedly connected with support 2, and the roller 1 is rotated against in support 2.The support 2 is what Open Side DownU-typed.
