Amatwi yamatwi akoreshwa muguhuza hose umuyoboro cyangwa bikwiye. Bafite icyuma gisohoka nk'ugutwi, niyo mpamvu izina ryabo. Impande z'ugutwi zifatanijwe hamwe kugirango zizenguruke impeta izengurutse hose kugirango uyifate mu mwanya.
Yubatswe mubyuma bidafite ingese, izi clamp zirwanya ruswa kandi ntizishobora kubora. Igishushanyo cyihariye cya cochlear gitanga imbaraga zikomeye zo kwagura ubushuhe bufasha kugumya hose neza.
Izi clamps ni ugutwi kumwe kandi ikubiyemo ubunini umunani busanzwe, harimo 6-7mm, 7-8.7mm, 8.8-10.5mm, 10.3-12.8mm, 12.8-15.3mm, 15.3-18.5mm, 17.8-21.0mm, 20.3-23.5mm. Amatwi yamatwi akoreshwa cyane mumasuka hamwe nu miyoboro ya pulasitike, kandi ikora neza cyane iyo bigeze kumazu yimashini zibinyobwa, ubwato, moto, ibinyabiziga, ndetse ninganda.

Nibikoresho byukuri bidafite intambwe bikozwe mubyuma bidafite ingese birinda ingese. Ifite igishushanyo cyoroshye cya 360 ° idafite intambwe bivuze ko nta ntambwe cyangwa icyuho kizengurutse imbere. Ibi bituma kashe yibanze hamwe na bande yayo ifunganye. Ifite kandi umurongo wihariye udasanzwe ugabanya ibyago byo kwangirika kubice bya hose bifatirwa.

Ruswa-Irwanya, ibyo bisobanuro bihanitse byamatwi bitagira intambwe ya clamps yubatswe kuva 304 ibyuma bidafite ingese kandi ntibishobora kubora kuburyo ari byiza kubikoresha igihe kirekire. Imbaraga ziyongereye zemerera gukoreshwa mugushiraho umurongo watypes ya clamps nkuko pincers zishobora kongera imbaraga zo gufatira. Izi clamps zikora cyane mugusana imiyoboro hamwe na sisitemu yo gukoresha amazi.

Ntabwo ibyo byuma byakozwe gusa kuva 304 ibyuma bitagira umwanda, ariko kandi birwanya ingese no kwangirika. Bashoboye gufunga byihuse kubishushanyo mbonera byabo byorohereza indishyi zo kwagura ubushyuhe. Biroroshye gukoresha kuva bafite ubushobozi bwa magnetique bwo kubifata mumwanya.
