Microprocessor Controlled Muscle Stimulation

Identifying the striated muscle during the surgical treatment of high and low anorectal malformation is an important requirement in Posterior sagittal anorectoplasty technique in surgery. It needs an electronic device that drives pulsated current intensities to allow transcutaneous stimulation at high current intensities and direct muscle stimulation at low current intensities. This paper reports the development of a programmable muscle stimulator capable of driving the required current intensity of pulsating nature into the muscle of the patient as programmed by the surgeon. The set current intensity does not vary with the changed muscle impedances seen by the probes while injecting the currents.
