Mashandiro Anoita Dental Handpieces

Mazino emaoko — anowanzozivikanwa semadhiri emazino — maturusi akakosha mukurapa mazino kwemazuva ano. Vanoita kuti vanachiremba vemazino vabvise kuora, kuumba mazino, kudzoreredza, uye kuita makiriniki akasiyana siyana nemazvo. Kunyange zvazvo zvingaratidzika zviri nyore kubva kunze,mazino handpiecessanganisira huinjiniya hwakaoma. Ichi chinyorwa chinotsanangura mashandiro anoita mazino emaoko, zvikamu zvawo zvikuru, uye mutsauko pakati pemhando dzakasiyana.

1. Basic Principle yeKushanda

Pakati pepakati, mazino handpiece anoshandurasimba(air pressure kana magetsi) kupindahigh-speed rotational kufambaanoshandiswa kuruka zviridzwa zvinonzikudzidza. Kutenderera uku kunobvumira vanachiremba vemazino kucheka enamel, dentin, kana prosthetic zvinhu zvakanaka uye zvisina njodzi.

Zvichienderana nemuenzaniso, handpiece inogona kushanda nekumhanya kubva:

• High-speed handpieces: 200,000–450,000 rpm

• Low-speed handpieces: 5,000-40,000 rpm

2. Zvikamu Zvikuru zveDental Handpiece

1. Kunobva Simba

Dental handpieces anowanzo shandisa:

• Maturbine anofambiswa nemhepo
  Inofambiswa nemhepo yakamanikidzwa inounzwa kuburikidza nechikamu chemazino. Mhepo inotenderera diki turbine rotor, ichigadzira kumhanya kwakanyanya.

• Magetsi emagetsi
  Shandisa micromotor yemagetsi kupa torque inowirirana pakumhanya kwakasiyana.

2. Turbine kana Motor

• Air-turbine handpiecesine rotor ine mashizha. Apo mhepo inoyerera, rotor inotenderera nokukurumidza.

• Magetsi handpiecesshandisa mota diki inotenderedza bur zvakananga.

3. Musoro uye Chuck System

Iyi ndiyo chikamu chinobatwa bur.
Thechuckmichina (push-bhatani kana wrench type) inochengetedza bur zvakasimba panguva yekushanda.

4. Bearings

Yepamusoro-chaiyo ceramic kana simbi mabhengi anotsigira kutenderera kweturbine, kuderedza kukweshera uye kuve nechokwadi chekutenderera kwakatsetseka pakumhanya kwakanyanya.

5. Kutonhodza uye Kupfapfaidza Mvura

Kudzivirira kupisa uye kudzivirira matishu, amvura spray systeminotonhorera mazino pamusoro panguva yekucheka.
High-speed handpieces inowanzoratidza atsaya katatu kana kuwanda-pfapfaidzadhizaini yekutonhora kunoshanda.

6. Fiber Optic kana LED Chiedza

Zvigadzirwa zvemazuva ano zvinowanzobatanidza kuvhenekera kwakavakirwa, zvichipa maonero akajeka enzvimbo yekushanda.

3. Mashandiro eHandpieces Yepamusoro-soro Anoshanda

High-speed handpieces inonyanya kuvimba nayoair-turbine simba:

1. Mhepo yakadzvanywa inopinda muhandpiece kuburikidza nemhepo chubhu.

2. Mhepo inorova mashizha eturbine, zvichiita kuti rotor itenderere.

3. Rotor's shaft yakabatana kune bur, iyo inotenderera nekumhanya kwakanyanya.

4. Chipfapfaidzo chemvura chinotonhodza buri nepamusoro pemazino.

5. Exhaust mhepo inobuda kuburikidza nematanho akasarudzwa.

Zvakanakira:

• Kumhanya kwakanyanya

• Yakareruka uye diki kugadzira musoro

• Smooth kucheka kunyatsoshanda

Kuganhurirwa:

• Yakaderera torque kana ichienzaniswa nemagetsi masisitimu

• Inogona kumira pasi pekumanikidzwa kukuru

4. Mashandiro Akaderera-Speed ​​Handpieces Anoshanda

Low-speed handpieces anowanzo shandisamota dzemagetsikanainjini dzemhepo.
Panzvimbo peiyo turbine, ivo vanovimba negiya masisitimu ekufambisa kutenderera kwekufamba.

Inoshandiswa ku:

• Kupukuta

• Kupedza

• Caries kubviswa

• Kugadzirisa mazino anobviswa

Ivo vanopa yakakwira torque asi yakaderera kumhanya, ichiita kuti ive yakakodzera kune yakanaka uye yakatetepa mabasa.

5. Kuchengetedza uye Kurarama Hurefu

Kugadzirisa kwakakodzera kunovimbisa kushanda kwemaoko uye kusimba. Izvi zvinosanganisira:

• Lubricationisati yaitwa sterilization

• Kuchenesazvikamu zvemukati

• Sterilizationmune autoclave

• Regular replacement ofma bearingsuyeO-mhete

Mahandpiece anochengetedzwa zvakanaka anovimbisa kushanda kwakapfava, hupenyu hurefu, uye kunyaradzwa kwemurwere kuri nani.

Dental handpieces chikamu chakakosha chemazuva ano dentistry, kubatanidza advanced mechanic engineering nekuita zvinoshanda. Ingave inofambiswa nemhepo kana yemagetsi, inomhanya-mhanya kana yakaderera-kumhanya, chinangwa chavo chinoramba chiri chimwe chete: kubatsira vanachiremba vemazino kuti vanyatsoita maitiro emazino nemazvo. Kunzwisisa mashandiro avanoita kunopa nzwisiso yakakosha mukuomarara kuseri kwechishandiso icho varwere vazhinji vanoona asi vasingambo nzwisise.
