The utility model provides an
oral cavity inspectoscope capable of being manually controlled to bend and deflect, which solves the problem that the traditional
oral cavity inspectoscope with a straight rod
handle is difficult to quickly adjust to a proper observation angle when a medical operator examines, and adopts the technical scheme that the
oral cavity inspectoscope comprises a
handle and an observation mirror, two rows of
helical-tooth-shaped convex blocks are symmetrically arranged on the two sides of the rib plate, the outer ends of the convex blocks are narrow, and the roots of the convex blocks are wide; symmetrical sliding grooves are formed in the two sides of the middle section of the
handle, sliding blocks are arranged in the sliding grooves in the two sides respectively, the sliding blocks are connected with a traction cable, and the traction cable sequentially penetrates through the two rows of oblique-tooth-shaped protruding blocks to be connected with an observation mirror. The protruding block is provided with a
push button on the outer side of the handle. When a medical operator holds the handle main rod and keeps still, the
push button is pushed by fingers, the
deflection angle of the observation mirror is adjusted, fine adjustment is carried out, the fine state of teeth is observed, examination is facilitated, gestures are flexibly moved and applied, and the treatment efficiency is greatly improved.
