ABSTRACT:
An instrument for direct current electrical therapy of hemorrhoidal lesions or the like in a patient consists of a D.C. electric generator, a grounding pad, a probe with distal tip for penetration of a lesion, and a handpiece for support of the probe and control of the level of current. The probe has a base and at least one electrode terminating in the distal tip. The handpiece has a lower handle to be gripped by a physician. The probe base is coupled to the handpiece, with the probe axis at an obtuse angle to the lower handle axis, the angle selected to allow a physician to hold the instrument without extended abnormal wrist flexure. Disposed generally above the lower handle is a front panel visible to the physician when the probe tip is penetrated into a lesion. The front panel includes a display of conditions disposed generally the line of sight of a physician with the probe tip. Controls for the level of current are disposed to allow a physician to operate the controls with digits of a hand gripping the handle.
