In transnasal endoscopic surgical procedures, the lens of the endoscope often becomes fogged or smeared with mucus or blood. The surgeon has to clean the lens and reintroduce the endoscope multiple times during the surgery, making it a tiring process.
This paper describes an innovative lens irrigation system comprising a modified 16 Fr Foley catheter, a 20 cc or 50 cc syringe filled with warm normal saline (0.9 per cent), and a commercially available intravenous infusion set. The rigid endoscope is introduced into the catheter through the urine draining port. When the lens gets smudged with blood or mucus, the irrigating saline in the syringe is forced through the inflating port.
A clear vision was restored immediately on flushing the syringe. The system did not compromise the operative space or hinder manoeuvrability.
This cost-effective, innovative lens irrigation system saves the time spent in cleaning the lens and enhances operational efficiency, especially in a low-income setting.
在经鼻内镜手术中，内镜镜头经常会被黏液或血液雾化或弄脏。外科医生在手术过程中不得不多次清洁镜头并重新插入内镜，这是一个很累人的过程。
本文介绍了一种创新的镜头冲洗系统，该系统由改良的 16 Fr Foley 导管、充满温生理盐水（0.9%）的 20 cc 或 50 cc 注射器和市售的静脉输液装置组成。刚性内镜通过排尿口插入导管。当镜头被血液或黏液弄脏时，注射器中的冲洗盐水通过充气口被强制冲洗。
冲洗注射器可立即恢复清晰视野。该系统不会影响手术空间或妨碍操作灵活性。
这种具有成本效益的创新镜头冲洗系统节省了清洁镜头的时间，提高了手术效率，尤其是在低收入环境下。
