Humeral Stem - Precision{0}}engineered Solutions rau Lub xub pwg Arthroplasty & Kho
Tsim los kho lub xub pwg nyom, kev ruaj ntseg, thiab tus neeg mob lub neej zoo, peb Humeral Stem system muab ntau yam ntawm precision-crafted implants rau thawj, kho, thiab complex lub xub pwg arthroplasty. Kev tsim kho nrog cov khoom siv siab heev thiab cov qauv tsim qauv anatomical, cov stems no ua kom zoo tshaj plaws osseointegration, rotational stability, thiab ntev -cov txiaj ntsig kev kho mob, hloov mus rau ntau tus neeg mob anatomies thiab kev xav tau kev phais.
Core Zoo
Advanced Material ScienceForged cobalt-chromium-molybdenum (CoCrMo) alloy rau cemented stems muaj qhov tshwj xeeb qaug zog tiv thaiv thiab biocompatibility, thaum cementless xaiv siv titanium alloy nrog Ti / HA dual- txheej txheej (500 ± 80μm) lossis 420μm (500μm) pores) los txhawb kev kho cov kab mob lom thiab ntev - lub sij hawm osseointegration.
Anatomical & Functional Design
Tri-tapered geometry: Muab kev ntxhov siab sib npaug thoob plaws lub humerus, txo cov kev ntxhov siab tiv thaiv thiab cov pob txha resorption thaum txhim kho kev sib hloov.
Matrix qhov loj me: Proximal/distal dimension sib xyaw ua ke (piv txwv li, #1–#7 qia qhov ntau thiab tsawg, 9–15mm distal diameters) phim ntau yam medullary canals kom haum haum.
Polished mos txwv tswv yim: Txo qhov kev ntxhov siab tsawg, txo qis qhov mob ntawm tus ncej puab, thiab pab txhawb kev cog qoob loo.
Cemented & Cementless Flexibility
Cemented stems:High- polished nto txo cov cement mantle kev sib txhuam thiab qaug zog puas tsuaj; spaced hlaws kom zoo li cement faib rau tam sim ntawd stability.
Cementless stems:Porous coatings (Ti / HA los yog titanium hlaws) muab ib tug scaffold rau pob txha ingrowth; tag nrho los yog qhov kev xaiv kev pab them nqi kho mob kom haum rau cov pob txha zoo sib txawv.
Revision & Complex Case SolutionsRevision stems feature short offset distances to address soft tissue scarring or contracture from before surgery, with 180mm ncaj (tsawg kawg ntawm cov pob txha) thiab 230mm nkhaus (medullary compromise) kev xaiv los hloov kho cov pob txha uas nws kim heev.
Modular Compatibility Seamlessly integrates nrog modular lub taub hau thiab bearing systems (hlau, ceramic, XPE liners) rau ob qho tib si anatomic tag nrho lub xub pwg arthroplasty (TSA) thiab rov qab xub pwg arthroplasty (RSA), streamlining phais workflows thiab expanding kev kho mob versatility.

Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov txawv ntawm cov cemented thiab cementless humeral stems, thiab kuv yuav xaiv qhov zoo rau kuv tus neeg mob li cas?
A: Cemented stems (forged CoCrMo, polished nto) muab kev ruaj ntseg tam sim ntawm cement fixation, ua rau lawv zoo tagnrho rau cov neeg mob uas muaj pob txha tsis zoo lossis pob txha pob txha. Cementless stems (Ti/HA los yog titanium hlaws coatings) txhawb ntev -lub sij hawm lom osseointegration, zoo dua haum rau cov hluas, active cov neeg mob nrog cov pob txha zoo. Qhov kev xaiv nyob ntawm cov pob txha zoo, cov neeg mob hnub nyoog, theem kev ua haujlwm, thiab kev nyiam ntawm tus kws phais.
Q: Cov qia humeral puas tuaj yeem siv rau hauv cov txheej txheem anatomic thiab thim rov qab lub xub pwg arthroplasty?
A: Yog. Peb qhov system tau sib xws nrog ob qho tib si anatomic tag nrho lub xub pwg arthroplasty (TSA) thiab rov qab lub xub pwg arthroplasty (RSA) teeb tsa. Lub modular tsim seamlessly integrates nrog coj glenoid Cheebtsam thiab bearing systems (hlau, ceramic, XPE) kom tau raws li cov kev xav tau ntawm txhua txoj kev.
Q: Yuav ua li cas tri-tapered tsim ntawm humeral qia txhim kho qhov tshwm sim?
A: Lub tri-tapered geometry faib kev ntxhov siab sib npaug thoob plaws hauv lub humerus, txo cov kev ntxhov siab tiv thaiv thiab cov pob txha zoo sib xws. Nws kuj tseem txhim kho kev sib hloov ruaj khov thaum cog thiab tom qab- ua haujlwm, txo qis micromotion thiab txhawb osseointegration. Rau cov cemented stems, qhov kev tsim no pab ua kom cov cement mantle rau cov khoom sib xws.
Q: Cov kev xaiv twg muaj rau kev kho mob nrog cov pob txha loj humeral?
A: Peb cov kev hloov kho humeral stems yog tsim rau cov teeb meem nyuaj: lub 230mm nkhaus qia haum rau medullary pob txha poob thiab anatomical variations, thaum tag nrho cov titanium plasma spray txheej txhawb kev kho mob lom nyob rau hauv cov pob txha puas. Modular Cheebtsam kuj tso cai rau proximal augmentation los yog distal fixation los daws qhov tsis xws luag.
Q: Puas yog humeral stems sib xws nrog tus qauv xub pwg arthroplasty instruments?
A: Yog. Lub kaw lus yog tsim los ua haujlwm nrog cov qauv orthopedic lub xub pwg nyom (reamers, broaches, impactors). Lub matrix sizing ua kom muaj kev sib raug zoo nrog cov cuab yeej uas twb muaj lawm, txo qhov kev xav tau ntawm cov cuab yeej tshwj xeeb thiab ua kom cov kev ua haujlwm ntawm kev phais.
