Abstract
The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices and systems with control knobs designed for improved usability and ergonomics. For example, the control knobs of the present disclosure may include surface features for improved gripping, surface features for improved perception of medical device orientation within a patient and/or knobs dimensioned for improved thumb reach and reduced torque.
Claims19
A medical device, comprising:
- a control handle operably attached to a proximal end of a shaft;
- a first control knob rotatably attached to the control handle via a first opening of the first control knob and configured to move a distal end of the shaft in a first direction;
- and
- a second control knob rotatably attached to the control handle via a second opening of the second control knob,
- wherein the first opening is geometrically centered within the first control knob;
- wherein the second opening is geometrically off-center within the second control knob;
- and
- wherein an outer circumference of the first control knob is defined by a plurality of radially outermost points, wherein a first lever arm length extending from the first opening to an end of a first radially outermost point is greater than a second lever arm length extending from the first opening to an end of a second radially outermost point of the plurality of radially outermost points, and wherein a first texture of the first radially outermost point is different from a second texture of the second radially outermost point.
