Description

Invenţia se referă la medicină, în special la oftalmologie. The invention relates to medicine, in particular to ophthalmology.

Este cunoscut dispozitivul pentru tratamentul cataractei senile, care include o seringă cu ac rectiliniu cu o lungime de 12 mm [1]. The device for the treatment of senile cataract is known, which includes a syringe with a straight needle with a length of 12 mm [1].

Este cunoscută metoda extracţiei extracapsulare a cataractei senile, care include următoarele etape tradiţionale: anestezie topică şi aseptizare obişnuită a câmpului operator, anestezie regională, aplicarea blefarostatului, fixarea muşchiului rect superior, incizia conjunctivei de la limb (orele 10°°…14°°), deschiderea camerei anterioare la ora 11°°, efectuarea capsulorexisului anterior prin introducerea separată a aerului steril şi a colorantului, formarea inciziei limbale (orele 10°°…14°°), luxarea nucleului în camera anterioară, înlăturarea acestuia în întregime, lavajul maselor cristaliniene, introducerea viscoprotectorului în camera anterioară, implantarea cristalinului artificial. Suturarea în surget a inciziei limbale. Suturarea separată a conjunctivei la orele 10°° şi 14°°. Subconjunctival se administrează un preparat steroid şi un antibiotic. Ulterior se aplică un pansament steril aseptic [2]. The method of extracapsular extraction of senile cataract is known, which includes the following traditional steps: topical anesthesia and usual asepsis of the operating field, regional anesthesia, application of blepharostat, fixation of the superior rectus muscle, incision of the conjunctiva at the limbus (10°°…14°°), opening of the anterior chamber at 11°°, performing anterior capsulorhexis by separately introducing sterile air and dye, forming the limbal incision (10°°…14°°), dislocation of the nucleus into the anterior chamber, its complete removal, lavage of the lens masses, introduction of viscoprotector into the anterior chamber, implantation of the artificial lens. Sudden suturing of the limbal incision. Separate suturing of the conjunctiva at 10°° and 14°°. A steroid preparation and an antibiotic are administered subconjunctivally. Subsequently, an aseptic sterile dressing is applied [2].

Dezavantajele constau în faptul că dispozitivul şi metoda cunoscută necesită efectuarea unei incizii penetrante la nivelul limbului de 2…3 mm, prin care uneori se scurge conţinutul camerei anterioare cu inclavarea în plagă a irisului. The disadvantages are that the known device and method require a penetrating incision at the limbus level of 2…3 mm, through which the contents of the anterior chamber sometimes leak, trapping the iris in the wound.

Problema pe care o rezolvă invenţia solicitată constă în elaborarea unui dispozitiv şi a unei metode de tratament al cataractei senile mai eficiente, care ar permite păstrarea conţinutului camerei anterioare cu poziţionarea corectă a irisului în timpul puncţiei limbale şi ar asigura efectuarea marcajului capsulei anterioare cristaliniene într-o singură etapă. The problem solved by the claimed invention consists in developing a more efficient device and method for treating senile cataract, which would allow preserving the contents of the anterior chamber with the correct positioning of the iris during limbal puncture and would ensure marking of the anterior lens capsule in a single step.

Esenţa invenţiei constă în aceea că dispozitivul pentru tratamentul cataractei senile include o seringă cu ac executat din două segmente unite sub un unghi de 90º, segmentul proximal are lungimea de 5 mm, iar cel distal - de 7 mm. Metoda de tratament al cataractei senile constă în aceea că se efectuează anestezia locală şi regională, se fixează muşchiul rect superior, se efectuează o incizie a conjuctivei la nivelul limbului, ce corespunde orelor 1000…1400, se efectuează puncţia camerei anterioare la nivelul limbului, ce corespunde orei 1100, cu ajutorul dispozitivului menţionat şi se introduc 0,3 ml de aer steril sub capsula cristalinului, apoi se marchează capsula anterioară a cristalinului prin introducerea a 0,2 ml de albastru de metilen, se efectuează o incizie circulară la nivelul limbului, ce corespunde orelor 1000…1300, se înlătură nucleul cristalinului, se efectuează lavajul maselor cristaliniene, se implantează cristalinul artificial, se suturează ţesuturile pe straturi, iar în spaţiul subconjunctival se introduce un antibiotic şi un remediu corticosteroid. The essence of the invention is that the device for the treatment of senile cataract includes a syringe with a needle made of two segments joined at an angle of 90º, the proximal segment has a length of 5 mm, and the distal one - 7 mm. The method of treatment of senile cataract consists in performing local and regional anesthesia, fixing the superior rectus muscle, making an incision of the conjunctiva at the level of the limbus, corresponding to 1000…1400 hours, performing a puncture of the anterior chamber at the level of the limbus, corresponding to 1100 hours, using the aforementioned device and introducing 0.3 ml of sterile air under the lens capsule, then marking the anterior lens capsule by introducing 0.2 ml of methylene blue, making a circular incision at the level of the limbus, corresponding to 1000…1300 hours, removing the lens nucleus, washing the lens masses, implanting the artificial lens, suturing the tissues in layers, and introducing an antibiotic and a corticosteroid remedy into the subconjunctival space.

Avantajele invenţiei propuse constau în aceea că utilizarea dispozitivului menţionat, încărcat în prealabil cu colorant - albastru de metilen şi aer steril, permite perforarea camerei anterioare, fără a efectua în prealabil o incizie limbală, fapt care deseori contribuie la evacuarea conţinutului camerei anterioare cu inclavarea în plagă a irisului, şi păstrarea profunzimii camerei anterioare folosind concomitent combinaţia aer steril şi colorant, de asemenea se efectuează cu uşurinţă marcajul capsulei anterioare cristaliniene. The advantages of the proposed invention consist in the fact that the use of the aforementioned device, previously loaded with dye - methylene blue and sterile air, allows the perforation of the anterior chamber, without previously performing a limbal incision, which often contributes to the evacuation of the contents of the anterior chamber with the iris being wedged in the wound, and preserving the depth of the anterior chamber using the combination of sterile air and dye, also easily marking the anterior lens capsule.

Rezultatul tehnic al invenţiei constă în abordul miniinvaziv, operativ şi eficace, păstrarea conţinutului camerei anterioare cu poziţionarea corectă a irisului în timpul puncţiei limbale cu dispozitivul menţionat, ceea ce permite într-o singură etapă (cu ajutorul combinaţiei de aer steril şi colorant) de a efectua şi marcajul capsulei anterioare cristaliniene. The technical result of the invention consists in the mini-invasive, operative and effective approach, preserving the contents of the anterior chamber with the correct positioning of the iris during the limbal puncture with the mentioned device, which allows in a single step (using the combination of sterile air and dye) to also perform the marking of the anterior lens capsule.

Invenţia se explică cu ajutorul figurii, care reprezintă imaginea generală: (1- piston; 2 - tub; 3 - ac). The invention is explained with the help of the figure, which represents the general image: (1- piston; 2 - tube; 3 - needle).
