D.O.R.C. MICRO DIATHERMY SYSTEM Section 1 Introduction The D.O.R.C. Micro Diathermy System is designed primarily for retinal detachment procedures (scleral diathermy and release of subretinal fluid). The instrument is also used for glaucoma procedures (cryclo diathermy and cauterization of lips of sclerotomy). The destruction of skin and intraocular tumors, hemostasis, epilation and trichiasis.
D.O.R.C. MICRO DIATHERMY SYSTEM Section 2 General Instructions. Standard components of the Micro Diathermy System.. The standard components of the Micro Diathermy system are: - Ophthalmic diathermy 13.56 MHz complete with power cord and foot switch. - Diathermy with transillumination. - Under water diathermy for both vitreous and anterior chamber surgery.
D.O.R.C. MICRO DIATHERMY SYSTEM Operating instructions. Check if the electrical supply the unit needs is correct (at the back-side). Plug the unit into the AC source outlet. C.1. Assembling accessories : The electrodes (1102-1111) are inserted into the handle assembly (1101) after unscrewing the chuck cap approximately one-half turn counterclockwise.
D.O.R.C. MICRO DIATHERMY SYSTEM Theory of operation Diathermy is used in operations for retinal detachment to produce a burn of the pigment epithelium. This burn is obtained by the applications of localized RF current on the sclera. A. Why High Frequency 13.56 MHz Power ? The following consideration resulted in the selection of the 13.56 MHz : Clinical tests have established that this frequency produces optimum burns of the pigment epithelium with the least possible damage to adjacent tissue such as the sclera and choroid.
