Femur Intramedullary Nail System
PFNA
PFNA ndi mtundu watsopano wa proximal femoral fixation system, kachitidwe katsopano komanso kabwino ka PFN (proximal femoral nail), aliyense amatengera zabwino za PFN yoyambirira, ali ndi mawonekedwe ofanana a biotechnological, ndipo ali ndi zatsopano pamapangidwe apadera kuti apangitse kukonza bwino komanso zosavuta kugwira ntchito.
γ-II Interlocking Intramedullary Nail
Mbali yachipatala ya 5 ° imalola kuyika pamwamba pa trochanter yaikulu (m'mimba mwake ndi 16.0mm)
Mapangidwe a Lateral flattening amathandizira kuyikako ndikuchepetsa kupsinjika kwa lateral cortical bone.
130 collodiaphysial angle (CCD)
Mapangidwe a nsonga ya elastic groove
Chotsani kuyikako
Chepetsani kupsinjika maganizo
Mapangidwe opindika atali amalepheretsa nsonga ya msomali kupita ku fupa la cortical
Chepetsani kukana kuyika komanso kuchuluka kwa ululu
Lag screw
Kuyika kwa screw lag kumatha kupereka kuphatikizika kwabwino kwa fupa la cancellous
Nsonga yotakata pamwamba imapatsa anangula bwino
Makamaka odwala osteoporotic
Anti-rotational ndi kukhazikika kumatheka ndi chinthu chimodzi chokha
Locking bolt
kapangidwe ka ulusi kawiri kuti muchepetse nthawi yogwira ntchito
End Cap
0/5/10/15mm kutalika Ndi kutalika koyenera kuti mutulutse

Mtengo wa FNS
Kwa kuphulika kwa khosi lachikazi (AOtype31-B), kuphatikizapo basilar, transcervical, ndi subcapital fractures
Kuchokera pamalingaliro a biomechanical, femoral neck dynamic cross misomali dongosolo ndi njira yothandiza yochizira kusakhazikika kwa khosi lachikazi.Izi zikuyimira ubwino wa ma implants omwe sali ochepa kwambiri.Kukhazikika kwake kumafanana ndi kachitidwe ka DHS ndipo ndikwabwino kuposa Hollow screw.
Zamgulu Detils
Anti-rotation screw
Kuchepetsa Kukula kwa Incision Chifukwa cha kukula kwake kwa implant, FNS imalola kuyika kosavuta - ngakhale kudzera pang'ono.
Kukhazikika kwabwino kwambiri
Msomali waukulu ndi zomangira zotsutsana ndi kuzungulira zimasungidwa mokhazikika ndi zotsekera zotsekera, zomwe zimatha kuteteza bwino kugwa kwa varus, kufupikitsa khosi lachikazi kapena kufupikitsa mwendo.
Kupanikizika kwa intraoperative
Chifukwa msomali waukulu ndi zotchinga zotsutsana ndi kuzungulira zimatsekedwa palimodzi, zonse zimatha kukakamizidwa mwamphamvu, mtunda ndi 20mm, ndipo malowo amasungidwa panja kuti apewe kukhumudwa komwe kumabwera chifukwa cha kukweza kwakunja kumlingo wina.
Yaing'ono implantation Space
Poyerekeza ndi zomangira zolimba za m'chiuno ndi zomangira zopanda kanthu, FNS ili ndi mawonekedwe apadera olowera m'mbale, omwe amachepetsa kutulutsa.Ndipo kamangidwe ka mbaleyo ndi kokongola, kulola kuikidwa ndi kang'ono kakang'ono kopanda kuwonongeka kwa minofu yofewa.
