Cannulated Headless Compression Screw

Cannulated Screw System cholinga chake ndi kukonza ma fractures, fusions, ndi osteotomies a mafupa akulu ndi ang'onoang'ono ndipo amakhala ndi zomangira ndi zochapira.

Ubwino waukulu wa zomangira zam'madzi ndikuti amatha kuyikidwa pamwamba pa waya wowongolera kapena pini yowongolera.M'mimba mwake pini yowongolera ndi yaying'ono kwambiri kuposa wononga zowombedwa ndipo imatha kuyikidwa molondola pogwiritsa ntchito fluoroscopy m'chipinda chopangira opaleshoni.Kuphatikiza apo, chifukwa cha kukula kwake kochepa, pini yowongolera imatha kubwezeretsedwa kangapo ngati kuli kofunikira kuti ikhazikike bwino popanda kuwonongeka kwakukulu kwa fupa.

Zokhala ndi mainchesi kuyambira ø2.4 mpaka ø7.3, zomangira zamzitini zimaphimba zisonyezo zambiri ndikuwonjezera chitonthozo kwa dotoloyo wokhala ndi ulusi wosiyanasiyana womwe umamulola kusankha zomangira zoyenera za fracture yomwe wapatsidwa.

Zomangira zonse zimawotchedwa kuti zigwiritsidwe ntchito pa waya wowongolera.Chilichonse wononga ndi pang'ono kapena kwathunthu ulusi ntchito cancellous dzino mawonekedwe.Zomangira zam'mafupa zimagwiritsidwa ntchito kwambiri m'chiuno, chiuno, bondo, akakolo, ndi phazi.Kuphulika kwa khosi lachikazi, kusokonezeka kwa mgwirizano wa sacroiliac, mapiri a tibial ndi kuphulika kwa chikazi cha intercondylar, kuphulika kwa calcaneal, fractures ya talar, ankle arthrodesis, subtalar arthrodesis, kupasuka kwa distal femur, ndi humeral, olecranon ntchito.

Zomangira zimawotchedwa kuti zigwiritsidwe ntchito pawaya wolondolera ndipo screw iliyonse imakhala ndi ulusi wochepa kapena wokwanira pogwiritsa ntchito ulusi woletsa.Cannulation imapangidwa kuti izingolowetsa pang'ono pang'onopang'ono percutaneous.Zomangira zomangika pang'ono zitha kugwiritsidwa ntchito kutsekereza chidutswa cha fupa kupita ku china, pomwe fupa lakutali limatengedwa ndi ulusi wa screw ndikukokera pafupi ndi kachidutswa ka cortex kumutu kwa screw.Zomangira zomangika bwino zimapangidwira kuti zigwiritsidwe ntchito kuti zikhazikike zosweka popanda kukanikizana pang'ono podutsa.

Kukwera kwamitengo yazaumoyo ndi njira zolipirira zotsatizana nazo kumabweretsa zosankha zotsika mtengo monga zomangira za cannulated.M'malo ophwanyika osasunthika, zomangira zimatha kupereka zotsatira zachipatala zofanana ndi zosankha zamtengo wapatali.

Amapangidwa kuti achepetse kukwiya kwa minofu yofewa poyerekeza ndi mitu yanthawi zonse.

Self-Tapping screw bit idapangidwa kuti ithandizire kuyika wononga ndipo imatha kuthetsa kufunikira kogogoda nthawi zina.
