Abstract

The lens blade is for use in cataract operations and incorporates a diamond incision point and an internal channel with a Luer cone. It makes post-operative disinfection of the insrument using successive disinfectants, together with drying in cold air possible without breakage of the blade point.

PHACO-MESPHACO-KNIFE

Beschrijving 5Description 5

Phaco-mes met diamanten mesje en inwendig kanaal met luer-conus. Het inwendig kanaal, in combinatie met de luer-conus, maakt post-operatief desinfecteren van het 10 instrument met achtereenvolgens desinfectans, aquadest en alcohol en het drogen met koude lucht mogelijk zonder dat het mesje afbreekt. Dit afbreken blijkt veelvuldig op te treden wanneer een phaco-mes wordt gedesinfecteerd volgens de voor de meeste chirurgische instrumenten gangbare methode: dit is de reden voor het gebruik van stalen disposables, terwijl oogchirurgen beroepshalve de voorkeur geven 15 aan een phaco-mes uit diamant. Het phaco-mes uit diamant kan naar verwachting minstens 500 maal worden gebruikt.Phaco knife with diamond blade and internal channel with luer cone. The internal channel, in combination with the luer cone, allows post-operative disinfection of the instrument with successive disinfectant, aquadest and alcohol and drying with cold air without the blade breaking off. This degradation appears to occur frequently when a phaco knife is disinfected by the method common to most surgical instruments: this is the reason for the use of steel disposables, while eye surgeons prefer a diamond phaco knife for professional reasons. The diamond phaco blade is expected to be usable at least 500 times.

Het phaco-mes wordt in de oogchirurgie toegepast bij cataract-operaties voor de noodzakelijke incisie onder het hoornvlies. Bij oogchirurgen bestaat een algemene 5 voorkeur voor een diamanten mesje, omdat bij gebruik daarvan de incisie gladder blijft dan bij gebruik van een stalen mes. Een gladde incisie geneest sneller en probleemlozer, met minder kans op postoperatief littekenweefsel, en maakt bovendien kostbare en tijdrovende hechtingen overbodig. Diamanten phaco-messen kunnen echter niet op de voor de meeste andere chirurgische instrumenten 10 gebruikelijke manier worden gedesinfecteerd, omdat bij deze werkwijze de mespunt veelvuldig zou afbreken. Van het standpunt van kostenbewaking bezien ligt daarom de huidige keuze voor het stalen disposable phaco-mes voor de hand. Het door Kuijpers Instruments ontwikkelde phaco-mes met diamanten punt kenmerkt 15 zich door een inwendig kanaal in combinatie met een luer-conus. Deze combinatie maakt desinfecteren van het mes met achtereenvolgens desinfectans, aquadest en alcohol, alsmede het drogen met koude lucht mogelijk volgens het principe van irrigatie en aspiratie bij het gebruik van naalden. Dit maakt handmatig desinfecteren van het phaco-mes, met het daaraan inherente 20 breukrisico, overbodig. Daardoor wordt toepassing van het phaco-mes met diamanten punt — dat, zoals reeds opgemerkt, de voorkeur van oogchirurgen geniet — in de praktijk haalbaar. De prijs van het hier beschreven phaco-mes is ongeveer het honderdvoudige van het thans gebruikelijke type met stalen mespunt, maar het kan naar verwachting 500 tot 600 maal worden gebruikt. In feite is de uiteindelijke 25 kostenbesparing groter, omdat disposable chirurgische instrumenten risicodragend afval zijn dat hoge verwerkingskosten met zich meebrengt. Op diamantmessen mag weliswaar geen ultrasone desinfectie worden toegepast (wegens lostrillen van het mesje), maar desinfecteren met vloeistoffen door het inwendig kanaal dat het door Kuijpers Instruments ontwikkelde phaco-mes kenmerkt, maakt ultrasone reiniging 30 overbodig.The phaco knife is used in eye surgery in cataract operations for the necessary incision under the cornea. Eye surgeons have a general preference for a diamond blade because the incision remains smoother when using it than when using a steel blade. A smooth incision heals faster and more smoothly, with less chance of postoperative scar tissue, and also eliminates the need for costly and time-consuming sutures. However, diamond phaco knives cannot be disinfected in the manner customary for most other surgical instruments, because the knife tip would frequently break off in this method. From the point of view of cost control, the current choice for the disposable steel phaco knife is therefore obvious. The phaco knife with diamond tip developed by Kuijpers Instruments is characterized by an internal channel in combination with a luer cone. This combination allows disinfection of the blade with successive disinfectant, aquadest and alcohol, as well as drying with cold air according to the principle of irrigation and aspiration when using needles. This makes manual disinfection of the phaco knife, with the inherent breakage risk, unnecessary. This makes the use of the diamond-tipped phaco knife - which, as already noted, is preferred by eye surgeons - practically feasible. The price of the phaco knife described here is about a hundredfold of the currently common steel knife tip type, but it is expected to be used 500 to 600 times. In fact, the ultimate cost savings are greater, because disposable surgical instruments are high-risk wastes that incur high processing costs. Although ultrasonic disinfection may not be applied to diamond knives (due to vibration of the blade), disinfection with liquids through the internal channel that characterizes the phaco knife developed by Kuijpers Instruments makes ultrasonic cleaning unnecessary.
