Technical Field

The invention relates to the technical field of dental surgical instruments, in particular to a connecting structure on a multifunctional curette.

Background

Curettes, also known as tooth curettes, are common dental instruments used in oral surgery to remove tooth debris, or to scrape away granulomas, cysts, diseased tissues in the alveolus, and broken bones. The prior curette consists of an excavating spoon (a curette or a curette blade) at two ends and a curette handle between the two ends, wherein the excavating spoon and the curette handle on one part of the curette are molded together, and a plurality of curettes are required to be provided because of various specifications of the excavating spoons; the other part of the curette can be detached from the curette handle, and then only one or two curette handles and the curettes of various types are needed, but the replacement and installation of the curette are troublesome in the existing detachable curette.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a connecting structure on a multifunctional curette, which is convenient for realizing replacement and assembly between a spoon digging part and a curette handle on the curette.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a connecting structure on a multifunctional curet comprises a round-rod-shaped handle, studs are respectively formed on two end faces of the handle, insertion holes extending to the handle are formed in the side end faces of the studs, each insertion hole comprises an outer hole and an inner hole, and a conical guide hole is formed between the outer hole and the inner hole; the double-screw bolt at two ends of the handle is screwed with a cap, a central hole is formed on the cap, a shaft sleeve communicated with the central hole is formed on the bottom surface of the inner side of the cap, the shaft sleeve is inserted in the outer hole of the double-screw bolt and is formed with a conical pressing sleeve, a plurality of cutting grooves are formed on the pressing sleeve, and the cutting grooves divide the pressing sleeve into a plurality of arc sheets;

the two ends of the handle are provided with curettes, each curette comprises a cylindrical plug, the plug is inserted into an inner hole of the handle, an insertion rod is formed on the plug, the insertion rod is inserted into a shaft sleeve and a central hole of the cap and extends out of the cap to form a special-shaped rod, and an excavating spoon is formed on the special-shaped rod; the outer wall of the pressing sleeve on the cap cover presses against the inner wall of the guide hole of the handle, and the side end face of the pressing sleeve presses against the end face of the plug.

Preferably, the stud on the handle is longer than the cap.

Preferably, the diameter of the outer hole on the handle is larger than that of the inner hole, and the diameter of the inner hole is equal to the diameter of the plug on the curette.

Preferably, the conical angle of the outer wall of the pressing sleeve on the cap cover is equal to the conical angle of the inner wall of the guide hole on the handle.

Preferably, the diameter of the plug on the curette is smaller than the diameter of the central hole on the cap.

Preferably, the cap is provided with at least three cutting grooves which are uniformly distributed in an annular shape around the central axis of the cap, the central axis of the insertion rod on the curette is coincided with the central axis of the plug, and the central axis of the plug, the central axis of the cap and the central axis of the handle are coincided.

Preferably, a plurality of first anti-skid lugs are formed on the outer wall of the cap, a plurality of second anti-skid lugs are formed on the outer walls of the two ends of the handle, and the second anti-skid lugs or the first anti-skid lugs are uniformly distributed on the handle or the cap in an annular shape.

Preferably, the diameter of the outer wall of the shaft sleeve on the cap is smaller than the diameter of the outer hole on the handle.

The invention has the beneficial effects that: the replacement and the assembly between the upper digging spoon part of the curette and the curette handle are conveniently realized.
