1. A surgical instrument, comprising: a handle assembly, the handle assembly comprising: a housing having a proximal end and a distal end, wherein the housing comprises a proximal opening at the proximal end of the housing and a distal opening at the distal end of the housing, and wherein a longitudinal axis passes through the distal opening and the proximal opening;a handle extending downwardly from the housing away from the longitudinal axis, the handle comprising a proximal contact surface, and a saddle surface positioned between the proximal contact surface and the housing; anda stabilization tail extending proximally from the handle and the housing;at least one distal instrument control;a yoke to translate an actuating member;a trigger, comprising: a first flange including a distally directed end, wherein the distally directed end is coupled to the yoke; anda second flange including a proximally directed end, wherein the proximally directed end is coupled to the handle assembly at a pivot point, wherein the pivot point has been positioned such that as the trigger pivots about the pivot point from an open position away from the handle to a closed position towards the handle a spread angle defined between a control finger location on one of the at least one distal instrument control and a trigger finger location on the trigger increases slightly, and wherein a linkage couples the yoke to the pivot point such that as the trigger pivots about the pivot point the yoke translates along the longitudinal axis; anda trigger hook fixedly coupled to the trigger to move with the trigger relative to the handle from the open position to the closed position, wherein the trigger and the trigger hook define an aperture therebetween. 2. The surgical instrument of claim 1, wherein the at least one distal instrument control comprises a distal rotation knob coupled to the housing at the distal opening, wherein the distal rotation knob comprising comprises a plurality of flutes. 3. The surgical instrument of claim 2, wherein the distal rotation knob comprises a resilient material. 4. The surgical instrument of claim 1, wherein the at least one distal instrument control comprises a distally-facing switch assembly comprising a toggle switch pivotably coupled to the distal end of the housing. 5. The surgical instrument of claim 1, wherein the proximal contact surface is defined by a first radius measured from a first reference point, the saddle surface is defined by a second radius measured from a second reference point, and the stabilization tail is defined by a third radius measured from a third reference point. 6. A surgical instrument, comprising: a handle assembly, the handle assembly comprising: a housing having a proximal end and a distal end, wherein the housing comprises a proximal opening at the proximal end of the housing and a distal opening at the distal end of the housing, and wherein a longitudinal axis passes through the distal opening and the proximal opening;a handle extending downwardly from the housing away from the longitudinal axis, the handle comprising a proximal contact surface, and a saddle surface positioned between the proximal contact surface and the housing; anda stabilization tail extending proximally from the handle and the housing;at least one distal instrument control comprising a distal rotation knob coupled to the housing at the distal opening, wherein the distal rotation knob is rotatable about the longitudinal axis;a yoke to translate an actuating member;a trigger, comprising: a first flange extending distally at an angle relative to the longitudinal axis, wherein the first flange is coupled to the yoke; anda second flange extending proximally at an angle relative to the longitudinal axis, wherein the second flange is coupled to the handle assembly at a pivot, wherein a location of the pivot has been selected such that as the trigger pivots about the pivot from an open position away from the handle to a closed position towards the handle an increase in a spread angle defined between a control finger location on one of the at least one distal instrument control and a trigger finger location on the trigger is minimized, and wherein a linkage couples the yoke to the pivot such that as the trigger pivots about the pivot the yoke translates along the longitudinal axis; anda trigger hook fixedly coupled to the trigger to move with the trigger relative to the handle from the open position to the closed position, wherein the trigger and the trigger hook define an aperture therebetween. 7. The surgical instrument of claim 6, wherein the distal rotation knob comprises a resilient material. 8. The surgical instrument of claim 6, wherein the at least one distal instrument control comprises a toggle switch pivotably coupled to the distal end of the handle assembly. 9. The surgical instrument of claim 6, wherein the proximal contact surface is defined by a first radius measured from a first reference point, the saddle surface is defined by a second radius measured from a second reference point, and the stabilization tail is defined by a third radius measured from a third reference point. 10. The surgical instrument of claim 6, wherein the saddle surface defines a first reference point along a second longitudinal axis parallel to the longitudinal axis, wherein the aperture defines a second reference point comprising the trigger finger location on the trigger, wherein the second reference point is located along a first vector having a first length d4 measured from the first reference point to the second reference point, and wherein the second reference point is located at a first angle φ4 measured between the first vector and the second longitudinal axis. 11. The surgical instrument of claim 10, wherein the first angle φ4 slightly increases as the trigger is pivotably rotated from a fully open position to a fully closed position. 12. The surgical instrument of claim 10, wherein the at least one distal instrument control comprises a toggle switch pivotably coupled to a distal portion of the housing between the distal opening and the trigger, and wherein the toggle switch comprises a first projecting knob defining a third reference point comprising the control finger location on the first projecting knob of the toggle switch. 13.
