Ai-trocar(noma i-trocar) iwumshini wezokwelapha noma wezilwane ohlanganisa i-awl (okungaba yinsimbi noma ipulasitiki enesihloko esicijile noma esingena-bladed), i-cannula (okuyisisekelo iyishubhu elingenalutho), kanye nophawu.Ngesikhathi sokuhlinzwa kwe-laparoscopic, i-trocar ifakwa esiswini.I-trocar isebenza njengengosi yokubekwa okulandelayo kwezinye izinsimbi ezifana ne-graspers,scissors,staplers,njll.I-trocar iphinde ivumele igesi noma uketshezi ukuthi luphume ezithweni zangaphakathi.
I-Etymology
Igama elithi trocar, i-trochar engavamile kakhulu lisuka ku-French trocart,trois-quarts (izingxenye ezintathu kwezine), lisuka ku-trois "ezintathu" kanye ne-carre "uhlangothi, ubuso bensimbi", okokuqala kwaqoshwa Ku-Dictionary of Arts and Sciences, 1694, nguThomas Cornell, umfowabo kaPierre Cornell.
Izinhlelo zokusebenza
Ukusetshenziswa kwezokwelapha/ngokuhlinzwa
Ama-Trocars asetshenziswa ngokwezokwelapha ukuthola nokukhipha ukunqwabelana koketshezi, njengasezigulini ezinokukhishwa kwe-pleural noma ama-ascites. Ezikhathini zanamuhla, ama-trocars okuhlinzwa asetshenziselwa ukwenza ukuhlinzwa kwe-laparoscopic. graspers, njll.ukwenza izinqubo ezizenziwe kuze kube manje ngokwenza izimbobo ezinkulu zesisu, ukuguqula ukunakekelwa kwesiguli.Ama-trocars okuhlinzwa asetshenziswa kakhulu namuhla njengamathuluzi esiguli esisodwa futhi ashintshile kusukela kumiklamo "yamaphuzu amathathu" ukuya "ku-spread-tip" enamahlombe ayisicaba imikhiqizo noma imikhiqizo engenasici ngokuphelele.Umklamo wokugcina unikeza ukuphepha okukhulu kwesiguli ngenxa yenqubo esetshenziselwa ukuzifaka.Ukufaka i-Trocar kungabangela inxeba lokubhoboza elinembobo esithweni esingaphansi, okuholela ezinkingeni zezokwelapha.Ngakho, isibonelo, ukufakwa kwe-laparoscopy intraperitoneal trocar kungabangela ukulimala kwamathumbu okuholela ku-peritonitis noma ukopha ngenxa yokulimala okukhulu komkhumbi.
Ukugqumisa
Ama-Trocars abuye asetshenziswe ngasekupheleni kwenqubo yokugqumisa ukuze anikeze ukugeleza koketshezi lomzimba nezitho zomzimba kulandela ukushintshwa kwemithambo yegazi ngamakhemikhali agqumisayo. Esikhundleni sokufaka ishubhu eliyindilinga, ummese onamacala amathathu we-trocar yakudala uhlukanisa isikhumba sangaphandle sibe kathathu " amaphiko"abe esesuthulwa kalula avalwe ngendlela engathandeki, inkinobho ye-trocar ingasetshenziswa esikhundleni se-sutures.Ixhunywe kwi-Tube ethambile emuncayo, evamise ukuxhunywa ku-aspirator yamanzi, kodwa i-aspirator yamanzi kagesi ingasetshenziswa. inqubo yokusebenzisa i-trocar ukukhipha amagesi, uketshezi, kanye nama-semisolids emigodini yomzimba nezitho ezingenalutho ibizwa ngokuthi i-aspiration. Faka ithuluzi ngamayintshi amabili ohlangothini lwesobunxele lomzimba (ngokwe-anatomically), amayintshi amabili ngaphezu kwenkaba.Ngemva kwesifuba, isisu ,futhi imigodi ye-pelvic iye yashiswa, umgqumisi ufaka imbobo yesifuba, yesisu, ne-pelvic, ngokuvamile esebenzisa i-trocar encane exhunywe ngepayipi elixhunywe ebhodleleni loketshezi olunenkomba ephezulu. vumela amandla adonsela phansi athwale uketshezi lwe-lumen lukhuphukele phezulu ku-trocar lungene kulume, isirinji yoketshezi inembobo encane yesithupha ukuze ilawule ukugeleza koketshezi.I-antiseptic ihambisa i-trocar ngendlela efanayo njengoba yenza lapho ifisa umgodi ukusabalalisa ikhemikhali. ngokwanele futhi ngokulinganayo, i-vial engu-1 yoketshezi lwe-cavity iyanconywa emgodini wesifuba kanye ne-vial engu-1 yomgodi we-peritoneal.
Ukusetshenziswa kwezilwane
Ama-Trocars asetshenziswa kakhulu odokotela bezilwane hhayi kuphela ukukhipha uketshezi lwe-pleural, ama-ascites, noma ukwethula izinsimbi ngesikhathi sokuhlinzwa kwe-laparoscopic, kodwa nasezimeni ezibucayi eziqondene nesilwane. Ezinjeni, inqubo efanayo ivame ukwenziwa ezigulini ezine-gastric distensible torsion, lapho i-trocar ene-bore enkulu ifakwa esikhumbeni esiswini ukuze iqede ngokushesha isisu. Kuye ngobunzima wezimpawu zomtholampilo ngesikhathi sokwethulwa, lokhu kuvame ukwenziwa ngemva kokuqaliswa kokuphathwa kobuhlungu kodwa ngaphambi kokubulala izinzwa okuvamile.Ukuphathwa kokuhlinzwa okuqondile kwakuhlanganisa ukubekwa kabusha kwe-anatomical kwesisu kanye nobende, okulandelwa yi-gastropexy engakwesokudla.Kuya ngobunzima, i-gastrectomy eyingxenye kanye/noma i-splenectomy. kungase kudingeke uma izicubu ezihambisanayo zine-necrotic ngenxa ye-ischemia ngenxa yokuqunjelwa/ukuvuvuka kwemithambo yokuphakela.
