Tremor Detection for Accuracy Enhancement in Microsurgeries Using Inertial Sensor
نویسندگان
چکیده
Physiological tremor is inherent in all humans. During surgeries accuracy of the hand held instrument also varies due to surgeons hand tremor and it and reduces surgeons capability to accurately manipulate instrument. This may cause irreversible damages to the small and delicate organs. Thus active cancellation of this tremor will improve manipulation accuracy in surgeries. In this paper we propose a simple algorithm for tremor measurement using low cost inertial sensor. Tool displacement due to tremor motion is estimated which further can be used for active cancellation of tremor.

Sensing Physiological Tremor in a Hand-held Microsurgical Instrument
INTRODUCTION Physiological tremor is an involuntary, approximately rhythmic and roughly sinusoidal movement [1]. It is inherent in all humans. The characteristics of physiological tremor are highly dependent on the body parts [2]. For instance, the frequency of tremor in the elbow ranges from 3 to 5 Hz while it ranges from 8 to 12 Hz in the wrist. Physiological tremor is benign for everyday tas...

A novel geometry for enhancing the sensitivity of intensity modulated refractometric fiber optic sensor for detection of adulteration level in diesel by kerosene is proposed. In this multimode plastic optical fiber is uncladded for specific length and bent into S shape. This geometry is simulated and analyzed using Beam Propagation Method in Beam prop RSOFT software. When sensor is immersed in ...
متن کاملQuantitative Assessment of Parkinsonian Tremor Based on an Inertial Measurement Unit
Quantitative assessment of parkinsonian tremor based on inertial sensors can provide reliable feedback on the effect of medication. In this regard, the features of parkinsonian tremor and its unique properties such as motor fluctuations and dyskinesia are taken into account. Least-square-estimation models are used to assess the severities of rest, postural, and action tremors. In addition, a ti...
متن کاملAdaptive band-pass filter (ABPF) for tremor extraction from inertial sensor data
Cancelling pathological tremor in everyday living activities may be possible with functional electrical stimulation (FES). One such feasible FES system with feedback from inertial sensors would rely on tremor estimates in real time. We present an adaptive band-pass filter (ABPF) that estimates tremor from volitional hand movement with zero-phase lag. The proposed algorithm is simple and easy to...
