Kugwiritsa ntchito mankhwala / opaleshoni
Ma Trocars amagwiritsidwa ntchito pachipatala kuti apeze ndi kukhetsa madzi, monga odwala omwe ali ndi pleural effusion kapena ascites. Masiku ano, opaleshoni ya opaleshoni imagwiritsidwa ntchito popanga opaleshoni ya laparoscopic. graspers, etc.kuti achite njira zomwe zakhala zikuchitika mpaka pano popanga zilonda zazikulu zam'mimba, kusintha chisamaliro cha odwala. Ma trocars opangira opaleshoni amagwiritsidwa ntchito kwambiri masiku ano ngati zida za wodwala m'modzi ndipo achokera ku mapangidwe a "magawo atatu" kupita ku "spread-nsonga" yokhala ndi lathyathyathya. mankhwala kapena mankhwala opanda blade kwathunthu.Mapangidwe omalizawa amapereka chitetezo chachikulu cha odwala chifukwa cha njira yomwe amagwiritsidwa ntchito kuti alowemo.Kuyika kwa Trocar kungapangitse chilonda cha perforated ku chiwalo chapansi, zomwe zimayambitsa zovuta zachipatala.Motero, mwachitsanzo, kuyika kwa laparoscopic intraperitoneal trocar Zitha kuyambitsa kuvulala kwam'mimba komwe kumatsogolera ku peritonitis kapena kutuluka magazi chifukwa chovulala kwambiri.
Kuumitsa mtembo
Ma Trocars amagwiritsidwanso ntchito chakumapeto kwa ndondomeko yowumitsa mitembo kuti apereke madzi amadzi am'thupi ndi ziwalo zotsatila m'malo mwa mtsempha wamagazi ndi mankhwala oumitsa. M'malo moyika chubu chozungulira, mpeni wambali zitatu wa trocar classic umagawa khungu lakunja kukhala katatu " mapiko "omwe amatsekedwa mosavuta kutsekedwa mochepa, batani la trocar lingagwiritsidwe ntchito m'malo mwa sutures." Imamangiriridwa ku chubu chofewa chofewa, chomwe nthawi zambiri chimagwirizanitsidwa ndi madzi aspirator, koma aspirator yamadzi yamagetsi ingagwiritsidwe ntchito. Njira yogwiritsira ntchito trocar kuchotsa mpweya, zamadzimadzi, ndi semisolids m'mabowo a thupi ndi ziwalo za dzenje zimatchedwa aspiration.Lowetsani chidacho mainchesi awiri kumanzere kwa thupi (anatomically), mainchesi awiri pamwamba pa navel. Pambuyo pa thoracic, mimba ,ndipo zibowo za m'chiuno zakhala zikulakalaka, woumitsa mitembo amalowetsa m'mimba, m'mimba, ndi fupa la m'chiuno, nthawi zambiri amagwiritsa ntchito trocar yaing'ono yolumikizidwa ndi payipi yolumikizidwa ndi botolo lamadzimadzi amtundu wapamwamba kwambiri. kulola mphamvu yokoka kunyamula lumen fluid kupita ku trocar ndi kulowa mu lumen, syringe yamadzimadzi imakhala ndi kabowo kakang'ono kakang'ono kamene kamayendetsa kayendedwe ka madzi. mokwanira komanso molingana, 1 botolo lamadzimadzimadzimadzimadzimadzimadzimadzimadzi amalimbikitsidwa pamimba ya thoracic ndi 1 vial ya peritoneal cavity.
Ntchito Chowona Zanyama
Trocars amagwiritsidwa ntchito kwambiri ndi veterinarians osati kukhetsa pleural fluid, ascites, kapena kuyambitsa zida panthawi ya opaleshoni ya laparoscopic, komanso pazochitika zachinyama zokhudzana ndi zinyama. Mu agalu, njira yofananira nthawi zambiri imachitidwa kwa odwala omwe ali ndi chapamimba distensible torsion, pomwe trocar yayikulu imalowetsedwa kudzera pakhungu m'mimba kuti ichepetse m'mimba nthawi yomweyo. za zizindikiro zachipatala pa nthawi yowonetsera, izi kawirikawiri zimachitika pambuyo poti chithandizo cha ululu chikutsatiridwa koma musanayambe opaleshoni. Zitha kufunidwa ngati minofu yolumikizana ndi necrotic chifukwa cha ischemia chifukwa cha kugwedezeka / kugwedezeka kwa mitsempha yodyetsa.
