睑板腺显微探针和睑板腺灌洗注药针的研制与临床应用

The research and clinical application of meibomian gland microprobe and meibomian gland lavage injection needle

目的研制一款适合门诊裂隙灯显微镜下睑板腺探通的睑板腺显微探针及睑板腺灌洗注药针。方法用7号注射针头，去除针锋，从针座插入0．16min×35mm／0．2min×35mm的针灸针至针管穿出，外露4．5mm，剪除针灸针柄固定于针管内，外露针芯作75°转折制成睑板腺探针，睑板腺扩张探针。用4号皮试针头除去针锋将前端管径缩小，研磨呈锥形钝头注药针。结果睑板腺阻塞的患者经睑缘清洁、局部表麻后于裂隙灯显微镜下均能顺利完成睑板腺探查疏通、探查扩张，睑板腺微量灌洗注药的临床要求。结论作者研制的睑板腺显微探针、睑板腺灌洗注药针是一款适合门诊裂隙灯显微镜下进行睑板腺探查、扩张、注药的器械，完全能满足各级医院需求及应用。

Objective To develop a Meibomian Gland Microprobe and a Lavage Injection Needle suitable for Meibomian Gland Probing under slit lamps. Methods The front of the 7th needle was removed. A size of 0.16×35/0.2×35 acupuncture needle from the needle file was inserted with 4.5mm exposed. The acupuncture needle handle was cut off and fixed it to the needle tube. 75° of the exposed needle core was turned to make a meibomian gland probe. The pinhead of the 4th skin-test needle was removed and then reduced the front inner size of the tube, grinding into a tapered blunt injection needle. Results For the patients with meibomian gland obstruction, after cleaning and local anesthesia to the eye lid, dredge was accomplished successfully, expansion and injection lavage to the meibomian glands under slit lamp. Conclusions The Meibomian gland Microprobe and meibomian gland lavage injection needle can work very well for Meibomian Gland Probing and dredging under slit lamps in clinics which will be a good method fulfill the clinical demands.
