A new multipurpose, low cost, ordinary flashlight drycell (1.5V) operated drill has been designed for conjunctival and corneal scrapings [Figure - 1].
| Description|| |
The motor and battery are enclosed in a two-piece plastic body. The motor is fixed in the anterior segment and is a sealed unit except for the metallic plate attached posteriorly for battery contact while the shaft projects out anteriorly, like a pencil, to engage the head. The posterior plastic case, enclosing the cell can be opened by unthreading. Hence the cell can be replaced as and when desired. [Figure - 2].
The head is engaged on the motor-shaft, projecting out. Various types of heads i.e, fine pointed, serrated and of nylon bristles (brush) have been designed to suit the particular need. [Figure - 3]. It is operated by a switch. After having fixed the head, motor is switched-on to revolve it rapidly. It is advanced towards the eye like, a pencil.
The effect of drilling depends upon the nature of head and the force applied on the tissue. The effect remains confined to a localised area only. The eye ball should preferably be fixed at the time of operation.
| Utility|| |
Nicholas et al for the first time used an electric drill for corneal rust removal and found it very useful in large deeply infiltrated tissues. As compared to an electric one, this has many additional advantages of being handy, portable, inexpensive and can be used in the out patients department or even bed side.
The instrument has been found very useful in scraping the corneal rusts, slough from ulcers, band shaped degenerations, conjunctival follicles and Bitot's spots. The head being metallic (except of nylon bristles), is easily sterilizable, The instrument is inexpensive (costing approx. Rs. 40/- only) ; and various other indigeneous heads can be prepared and fitted as per need. A more powerful one can be operated by two cells (3 volts).
