Description

A single-head scaler for dental surgery

Technical field:

The invention relates to the technical field of surgical instruments and equipment, in particular to a single-head scaler for dental surgery.

Background technique:

When carrying out scaling operation to gingivitis, periodontitis etc. in the existing dental operation, calculus and bacterial plaque etc. on the root surface in the periodontal pocket are scraped with scaler, and existing scaler is generally in The handle is directly formed with a curettage head. Generally, after one person uses it, the curettage device needs to be replaced. Although the curettage head must be replaced, the handle can actually be used many times, so waste is generated.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a single-head scaler for dental surgery, which has a detachable installation connection part, and a scaler head is directly formed on the installation connection part, so that it can be used directly after one use. The installation connection part is replaced without replacing the handle body, which saves environmental protection and improves the use time of the handle.

The scheme that the present invention solves described technical problem is:

A single-head scaler for dental surgery, comprising a handle body, the left end of the handle body is formed with a head connection hole, one end of the installation connection part is formed with a scaling head, and the other end of the installation connection part is formed with a mounting rod, The installation rod is inserted into the corresponding head connecting hole. There are multiple radial screw holes formed on the installation rod. The double-headed ball plunger is screwed in the radial screw hole. The two spheres are nested in the concave holes formed on the inner wall of the head connection hole;

The outer wall of the right end of the handle body has an external thread, the extension sleeve is screwed into the external thread, the outer wall of the right end of the extension sleeve is formed with an external connecting thread, and the positioning support sleeve is screwed in the external connecting thread.

An elastic non-slip silicone sleeve is fixed on the outer wall of the handle body.

The left end of the handle body is formed with an annular groove, the elastic sealing ring is nested in the annular groove, and the end surface of the installation connecting part with the installation rod is pressed against the elastic sealing ring.

The installation connection part is a conical block.

A scraping head is formed at the end of the small-diameter end of the installation connection part, and a mounting rod is formed at the middle of the end part of the large-diameter end of the installation connection part.

The outstanding effect of the present invention is: compared with the prior art, it has a detachable installation connection part, and a scraping head is directly formed on the installation connection part, so that the installation connection part can be directly replaced after one use without changing the handle The main body saves environmental protection and improves the use time of the handle.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is a partial enlarged view of the present invention.

Detailed ways:

Embodiment, as shown in Fig. 1 to Fig. 2, a kind of single-head scaler for dental operation includes a handle body 10, the left end of the handle body 10 is formed with a head connection hole 13, and one end of the connection part 14 is installed A scraping head 15 is formed, and a mounting rod 141 is formed at the other end of the mounting connection part 14. The mounting rod 141 is inserted into the corresponding head connection hole 13, and a plurality of radial screw holes 142 are formed on the mounting rod 141. , the double-headed ball plunger 143 is screwed in the radial threaded through hole 142, and the two balls of the double-headed ball plunger 143 are nested in the concave hole 131 formed on the inner wall of the head connection hole 13 ;

The outer wall of the right end of the handle body 10 has an external thread 101, the extension sleeve body 12 is screwed into the external thread 101, the outer wall of the right end of the extension sleeve body 12 is formed with an external connecting thread 121, and the positioning support sleeve 122 is screwed on the external connecting thread 121 middle.

Furthermore, an elastic non-slip silicone sleeve 16 is fixed on the outer wall of the handle body 10 .

Furthermore, the left end of the handle body 10 is formed with an annular groove 17, and the elastic sealing ring 18 is nested in the annular groove 17, and the installation connection part 14 has an end surface of the installation rod 141 pressed against the elastic sealing ring 18 superior.

Furthermore, the installation connection part 14 is a conical block.

Furthermore, the small-diameter end of the installation connection part 14 is formed with a scraping head 15 , and the middle part of the large-diameter end of the installation connection part 14 is formed with an installation rod 141 .

When this embodiment is in use, after the scraping head 15 is used up, its installation connection part 14 can be pulled out directly from the handle body 10, and the double-headed ball plunger 143 can be removed to replace the new installation connection part 14 It is very convenient to screw the removed double-headed ball plunger 143 into the installation rod 141 of the new installation connection part 14, and insert it into the corresponding head connection hole 13 for snap connection.

And because the grip handle body 10 is generally a pen-holding grip, the length of the grip can be increased by screwing the extension sleeve 12, which is convenient for people with big hands to grip, and the positioning support sleeve 122 that is screwed makes the grip The thumb and forefinger of the holding hand can be pressed against the positioning support sleeve 122 to realize support and improve the holding effect.

Finally, the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical fields can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the category of the present invention, and the scope of patent protection of the present invention should be defined by the claims.
