Aitrocar(okanye i-trocar) sisixhobo sonyango okanye sonyango lwezilwanyana esiquka i-awl (esenokuba yintsimbi okanye iplastiki enencam etsolo okanye engeyo-bladed), i-cannula (isiseko esiyityhubhu engenanto), kunye netywina.Ngexesha lotyando lwelaparoscopy, itrocar ifakwe kwisisu.I-trocar isebenza njenge-portal yokubekwa okulandelayo kwezinye izixhobo ezifana ne-graspers, scissors, staplers, njl.I-trocar ivumela igesi okanye ulwelo ukuba lubaleke kwizitho zangaphakathi.
I-Etymology
Igama elithi trocar, i-trochar engaqhelekanga eqhelekileyo ukusuka kwi-French trocart, i-trois-quarts (ikota ezintathu), ukusuka kwi-trois "ezintathu" kunye ne-carre "icala, umphezulu wesixhobo", okokuqala kubhalwe kwiDictionary of Arts and Sciences, 1694, nguThomas Cornell, umntakwabo Pierre Cornell.
Usetyenziso
Ukusetyenziswa kwezonyango/ngotyando
I-Trocars isetyenziselwa unyango ukufumana kunye nokukhupha i-accumulations ye-fluid, njengakwizigulane ezine-pleural effusion okanye i-ascites. graspers, etc.ukwenza iinkqubo ukuza kuthi ga ngoku ngokwenza amanxeba esisu esikhulu, ukuguqula ukhathalelo lwesigulane.Iitrocars zotyando zisetyenziswa kakhulu namhlanje njengezixhobo zesigulana esinye kwaye ziye zavela kuyilo lwe "point-three" ukuya kwi-"spread-tip" enamacangca acwecwe iimveliso okanye iimveliso ezingenasiphako ngokupheleleyo.Uyilo lokugqibela lunikeza ukhuseleko olukhulu lwesigulane ngenxa yobuchule obusetyenziselwa ukuzifaka.Ukufakwa kweTrocar kunokubangela ukuba inxeba le-perforated puncture kwilungu elingaphantsi, elikhokelela kwiingxaki zonyango.Ngoko, umzekelo, ukufakwa kwe-laparoscopic intraperitoneal trocar kunokubangela ukwenzakala emathunjini okukhokelela kwi-peritonitis okanye ukopha kwingozi enkulu yenqanawa.
Ukuqhola isidumbu
IiTrocars zikwasetyenziswa ngasekupheleni kwenkqubo yokuqholwa kwesidumbu ukubonelela ngamanzi olwelo lomzimba kunye namalungu emva kokutshintshwa komthambo wegazi ngeekhemikhali zokuqholwa. Endaweni yokufaka ityhubhu engqukuva, imela enamacala amathathu yetrocar yahlula ulusu lube luthathu " amaphiko"athi emva koko atyhutyhwe ngokulula avale ngendlela engathandekiyo, iqhosha letrocar linokusetyenziswa endaweni ye-sutures.Incanyathiselwe kwiThubhu ethambileyo efunxayo, edla ngokuqhagamshelwa kwi-aspirator yamanzi, kodwa i-aspirator yamanzi yombane nayo ingasetyenziswa. Inkqubo yokusebenzisa i-trocar ukususa iigesi, ulwelo, kunye ne-semisolids kwimingxuma yomzimba kunye namalungu angenanto ibizwa ngokuba yi-aspiration. ,kwaye imingxuma ye-pelvic iye yanqwenelwa, umqholi ufaka i-thoracic, isisu, kunye ne-pelvic cavities, ngokuqhelekileyo usebenzisa i-trocar encinci edityaniswe ngumbhobho oqhagamshelwe kwibhotile ye-high-index cavity fluid.Ibhotile ibanjwe phezulu emoyeni ukuya vumela ubunzima bokuthwala i-lumen fluid ukuya kwi-trocar kunye ne-lumen, isirinji yamanzi inomngxuma omncinci wokulawula ukuhamba kwamanzi. ngokwaneleyo kwaye ngokulinganayo, i-1 i-vial ye-cavity fluid iyacetyiswa kwi-thoracic cavity kunye ne-1 vial ye-peritoneal cavity.
Ukusetyenziswa kwezilwanyana
IiTrocars zisetyenziswa kakhulu ngoogqirha bezilwanyana kungekuphela nje ukukhupha ulwelo lwe-pleural, i-ascites, okanye ukwazisa izixhobo ngexesha lotyando lwe-laparoscopic, kodwa nakwiimeko ezibukhali zezilwanyana. Kwizinja, inkqubo efanayo idla ngokusetyenziswa kwizigulane ezine-gastric distensible torsion, apho i-trocar enkulu ifakwe ngesikhumba esiswini ukuze ithobe ngokukhawuleza isisu. iimpawu zeklinikhi ngexesha lokubonisa, oku ngokuqhelekileyo kwenziwa emva kokulawulwa kweentlungu kodwa ngaphambi kokuba u-anesthesia jikelele. kunokufuneka ukuba izicubu ezinxulumene ne-necrotic ngenxa ye-ischemia ngenxa ye-torsion / avulsion ye-vasculature yokutya.
