[0005] The working section is half to one third of the length of handle section.

[0006] The root of working section is fixed by thread connection with working section connecting seat.

[0007] The handle section is connected with extension rod at rear part.

[0008] The distance between the steering wheel and the driving wheel is 10-15 cm.

[0009] The utility model discloses a have's advantage and beneficial effect is: the utility model discloses handle section utilizes the square tubular shell inside setting has the front end steering wheel and the driving wheel of rear part, sets up the towrope between the support plate of two sides round sheet of steering wheel and driving wheel through the support, and the steering wheel utilizes towrope to drive the rotation of steering wheel, can drive the steering wheel rotation through the arc direction rotation of the push handle left and right direction of driving wheel, and drive the curved hook needle end connected in left and right direction steering of work section connecting seat, thereby can form the steering dental probe. Therefore, the medical treatment operator can control the steering dental probe steering through the finger push handle of driving wheel when checking the oral cavity and dental of patient, avoids blocking the observation field of medical treatment operator, and the convenient check, nimble movement uses the gesture, and the efficiency of treatment is greatly improved.
