Description

Invenţia se referă la medicină, şi anume la chirurgie, şi poate fi utilizată pentru fluidizarea şi aspiraţia conţinutului chistului hidatic în tratamentul echinococozei hepatice. The invention relates to medicine, namely to surgery, and can be used for fluidization and aspiration of the contents of the hydatid cyst in the treatment of hepatic echinococcosis.

Este cunoscut procedeul şi dispozitivul de fluidizare a conţinutului chistului hidatic hepatic pe cale mecanică. Procedeul de fluidizare constă în introducerea în interiorul chistului hidatic a unei tije fixate într-un dispozitiv de tip mixer, pe capătul tijei fiind articulată o paletă rabatabilă. Tija dispozitivului este antrenată în mişcare de rotaţie cu o viteză de 500...1000 rot/min, pe o durată de 3...5 min, astfel că paleta rabatabilă realizează fragmentarea mecanică şi fluidizarea conţinutului chistic, facilitând evacuarea acestuia în exteriorul cavităţii peritoneale, cu ajutorul unui mijloc de aspiraţie. În chirurgia laparoscopică, ghidarea tijei rotative a dispozitivului de fluidizare se face cu ajutorul unui trocar adecvat. Dispozitivul de fluidizare este compus dintr-o tijă rotativă, antrenată în mişcare de rotaţie, printr-un manşon elastic, de un ansamblu motoreductor acţionat electric. Pe capătul distal al tijei rotative este articulată o paletă rabatabilă care, sub acţiunea forţelor centrifuge, se distanţează la diferite unghiuri, realizând fragmentarea mecanică şi fluidizarea conţinutului chistului hidatic [1]. The process and device for fluidizing the contents of the hepatic hydatid cyst mechanically are known. The fluidization process consists in introducing a rod fixed in a mixer-type device into the hydatid cyst, a folding blade being articulated on the end of the rod. The rod of the device is driven into rotation at a speed of 500...1000 rpm, for a duration of 3...5 min, so that the folding blade performs the mechanical fragmentation and fluidization of the cystic content, facilitating its evacuation outside the peritoneal cavity, with the help of a suction means. In laparoscopic surgery, the rotating rod of the fluidization device is guided using an appropriate trocar. The fluidization device is composed of a rotating rod, driven into rotation, through an elastic sleeve, by an electrically driven gearmotor assembly. A folding blade is articulated on the distal end of the rotating rod which, under the action of centrifugal forces, moves apart at different angles, achieving mechanical fragmentation and fluidization of the hydatid cyst contents [1].

Dezavantajele procedeului constau în aceea că extremitatea distală care penetrează membrana conjunctivă a chistului este ascuţită, astfel este posibilă doar omogenizarea jumătăţii superioare a chistului, iar forţarea dispozitivului poate duce la lezarea fundului cavităţii hidatice, unde sunt localizate elemente bilio-vasculare cu lezarea lor şi provocarea unor complicaţii postoperatorii. The disadvantages of the procedure are that the distal extremity that penetrates the cyst's conjunctival membrane is sharp, thus only the upper half of the cyst can be homogenized, and forcing the device can lead to damage to the bottom of the hydatid cavity, where biliovascular elements are located, damaging them and causing postoperative complications.

Problema pe care o rezolvă invenţia constă în elaborarea unui procedeu de omogenizare a masei intrachistice în întregime, fără lezare de structuri bilio-vasculare cu scop de profilaxie a complicaţiilor postoperatorii. The problem solved by the invention consists in developing a process for homogenizing the entire intracystic mass, without damaging the biliovascular structures, with the aim of preventing postoperative complications.

Esenţa invenţiei constă în efectuarea abordului laparoscopic cu introducerea dispozitivului optic şi instalarea pneumoperitoneului, după care se determină localizarea chistului hidatic, în peretele abdominal în proiecţia chistului se efectuează un abord suplimentar, prin care se introduce un tub de ghidare până la poziţionarea capătului pe capsula chistului, în tubul menţionat se introduce un alt tub cu capătul lucrativ ascuţit sub un unghi de 45°, se perforează chistul, apoi cu ajutorul unui dispozitiv de aspiraţie conectat la tubul extern prin intermediul unor racorduri se absoarbe lichidul hidatic. În tubul intern se introduce un tocător electric cu un ajutaj din lamele spiralate şi se fragmentează membranele hidatice cu viteza de 500...1000 rot./min, timp de 3...5 min, până la omogenizare, se aspiră conţinutul chistic, după care se prelucrează cavitatea restantă. The essence of the invention consists in performing a laparoscopic approach with the introduction of the optical device and the installation of pneumoperitoneum, after which the location of the hydatid cyst is determined, an additional approach is performed in the abdominal wall in the projection of the cyst, through which a guide tube is inserted until the end is positioned on the cyst capsule, another tube with a sharp, lucrative end at an angle of 45° is inserted into the said tube, the cyst is perforated, then with the help of a suction device connected to the external tube by means of connections, the hydatid fluid is absorbed. An electric chopper with a nozzle made of spiral blades is inserted into the internal tube and the hydatid membranes are fragmented at a speed of 500...1000 rpm, for 3...5 min, until homogenization, the cystic content is aspirated, after which the remaining cavity is processed.

Rezultatul constă în omogenizarea totală a membranelor chistului hidatic hepatic, fără lezarea vaselor şi ducturilor biliare deschise în cavitatea reziduală. Procedeul revendicat poate fi folosit în toate cazurile de intervenţie chirurgicală pe cale laparoscopică la ficat cu echinococoză, cu evitarea desiminării abdominale. The result is the total homogenization of the membranes of the hepatic hydatid cyst, without damaging the vessels and bile ducts open in the residual cavity. The claimed process can be used in all cases of laparoscopic surgical intervention on the liver with echinococcosis, avoiding abdominal dissection.

Metoda revendicată se explică prin figurile 1-2, care reprezintă: The claimed method is explained by figures 1-2, which represent:

- fig. 1, amplasarea tocătorului în cavitatea chistului hidatic; - Fig. 1, placement of the chopper in the hydatid cyst cavity;

Procedeul se efectuează în modul următor. The procedure is carried out in the following way.

După spitalizarea pacientului, se efectuează examenele clinice şi paraclinice cu stabilirea localizării chistului hidatic hepatic. Se efectuează anestezie generală şi prelucrarea câmpului operator, apoi se efectuează intervenţia prin abord laparoscopic cu introducerea dispozitivului optic şi instalarea pneumoperitoneului, după care se determină localizarea chistului hidatic, în peretele abdominal în proiecţia chistului se efectuează un abord suplimentar, prin care se introduce un tub de ghidare până la poziţionarea capătului pe capsula chistului, în tubul menţionat se introduce un alt tub cu capătul lucrativ ascuţit sub un unghi de 45°, se perforează chistul, apoi cu ajutorul unui dispozitiv de aspiraţie conectat la tubul extern prin intermediul unor racorduri se absoarbe lichidul hidatic. În tubul intern se introduce un tocător electric cu un ajutaj din lamele spiralate şi se fragmentează membranele hidatice cu viteza de 500...1000 rot./min, timp de 3...5 min, până la omogenizare, se aspiră conţinutul chistic, după care se prelucrează cavitatea restantă. După efectuarea procedeului revendicat, cavitatea restantă poate fi supusă intervenţiei de marsupializare cu lichidarea ei. After the patient is hospitalized, clinical and paraclinical examinations are performed to determine the location of the hepatic hydatid cyst. General anesthesia and preparation of the surgical field are performed, then the intervention is performed through a laparoscopic approach with the introduction of the optical device and the installation of pneumoperitoneum, after which the location of the hydatid cyst is determined, an additional approach is performed in the abdominal wall in the projection of the cyst, through which a guide tube is inserted until the end is positioned on the cyst capsule, another tube with a sharp, lucrative end is inserted into the aforementioned tube at an angle of 45°, the cyst is perforated, then with the help of a suction device connected to the external tube by means of connections, the hydatid fluid is absorbed. An electric chopper with a spiral blade nozzle is inserted into the internal tube and the hydatid membranes are fragmented at a speed of 500...1000 rpm for 3...5 min until homogenized, the cystic content is aspirated, after which the remaining cavity is processed. After performing the claimed procedure, the remaining cavity can be subjected to marsupialization intervention with its liquidation.
