New R&D dhizaini

MIS | Technological Upgrade - Technological Advantages - Post-operative Results | czmeditech

Iyo Minimally Invasive Spine System (MIS) inyanzvi yemazuva ano inogonesa kurapwa kwakanyatso kuburikidza nediki diki remamiriro ezvinhu senge herniated discs uye spinal stenosis.

Tsanangudzo itsva yekugadzira

Minimally invasive zvakanakira

Minimized trauma

Diki dhizaini:

Yakajairika incision ingori 1-2 cm, inoderedza kubviswa kwemhasuru uye kukuvara kwematishu akapfava.

Precision Positioning tekinoroji:

Kuvandudzwa kwechokwadi chekuisa kuiswa nekufamba kwemukati (semuenzaniso O-ruoko, 3D-C-ruoko) kana rubatsiro rwerobhoti (semuenzaniso Mazor X, Globus Medical).

Yakaderedzwa intraoperative kubuda ropa:

minimally invasive access tekinoroji inoderedza njodzi yekukuvara kwevascular, kunyanya kune vakwegura kana varwere vane comorbid.

Kukurumidza postoperative kupora

Kugara kwenguva pfupi muchipatara:

varwere vazhinji vanoburitswa 24-48 maawa mushure mekuvhiyiwa, zvichienzaniswa ne3-5 mazuva ekuvhiyiwa kwechinyakare.

Kufamba kwekutanga:

Kusanyanya kurwadziwa uye kuchengetedzwa kwemhasuru kuri nani kunobvumira varwere kudzokera kumabasa avo ezuva nezuva nekukurumidza.

Biomechanical optimization

Zvitsva zvekushandisa:

eg 3D yakadhindwa titanium alloys, PEEK (polyether ether ketone) zvinhu kuti zviwane modulus ye elasticity pedyo neyo bone uye kuderedza kushungurudzika masking.

Dynamic kudzikamisa masisitimu:

mamwe ma implants (eg Dynesys, Coflex) inochengetedza kufamba kwemusana uye kuderedza njodzi yekuderera kwechikamu chepedyo.

Zviratidzo zvakawedzerwa

Kuvhara zvakasiyana-siyana zvepinal pathologies zvakadai se degenerative disc chirwere, lumbar spinal stenosis, mild spondylolisthesis uye vertebral fractures.

临床案列

Aya anotevera ndeaya anomiririra nyaya dzekutsvagisa mumakore achangopfuura:

1. Randomized controlled trial ye lumbar spine fusion (TLIF)

Dhizaini yekudzidza:

anotarisira multicenter RCT (2022) achienzanisa MIS-TLIF (zvishoma invasive) ine yakavhurika TLIF.

Saizi yemuenzaniso

120 varwere vane single-segment degenerative lumbar spine chirwere.

Mhinduro:

Nguva yekuvhiya:

kureba zvishoma muboka reMIS (kureva 150 min vs. 130 min), asi 60% kushoma kubuda ropa (<100 ml vs. 250 ml).

Postoperative kurwadziwa:

50% kuderedza muVAS zvikoro 1 vhiki mushure mekushanda muboka reMIS, hapana musiyano mukuru pakati pemapoka maviri mushure memwedzi ye3.

Fusion rate:

1 gore postoperative CT yakaratidza> 90% fusion rate mumapoka maviri.

Zvinetso:

Chiyero chetachiona 2% muboka reMIS vs. 8% muboka rakashama.

2. Kudzidza kwenguva refu kwekutevera kweiyo dynamic stabilization system (Coflex)

Dhizaini yekudzidza:

European 5-gore yekutevera yekudzidza (2021) kuongorora Coflex implantation yekurapa lumbar spinal stenosis.

Saizi yemuenzaniso

80 varwere.

mhedzisiro:

Kuvandudza kushanda:

iyo ODI (dysfunction index) yakadzikira kubva pamakumi mana neshanu mapoinzi kusvika pamakumi maviri pamakore mashanu.

CHIKAMU CHEMUVAKIDZANO KUDZIDZWA:

Chete 12% yevarwere vakagadzira matambudziko echikamu chepedyo, zvakanyanya kuderera kupfuura kusanganiswa kwakajairwa (~ 30%).

Reoperation rate:

yakawedzera 5-gore reoperation mwero we8%, kunyanya nekuda kwekudyara kusunungura (4%) kana chiratidzo chekudzoka.

3. Kudzidza kwakawanda kwemarobhoti-anobatsira MIS kudyara

Dhizaini yekudzidza:

retrospective chidzidzo chakaburitswa muna 2023 kuongorora mhedzisiro yeMIS screw kuiswa neMazor robhoti rubatsiro.

Saizi yemuenzaniso

500 screw placements (thoracolumbar musana).

Mhinduro:

Precision:

98.6% yescrew positions yaigutsa (Gertzbein-Robbins grading A/B).

Zvinetso:

nerve midzi kukuvara mwero 0.4% zvichienzaniswa ne3-5% yezvakajairwa freehand kuiswa.

Kuti uwane rumwe ruzivo rwechigadzirwa uye ruzivo, ndapota taura nesu!
