Surgical device
A medical instrument comprising: (A) a first joint comprising a first member and a second member, the first member configured to be repositionable with respect to the second member in an X-Y plane; (B) a second joint operatively coupled to the first joint, the second joint comprising a third member and a fourth member, the third member configured to be repositionable with respect to the fourth member in a Y-Z plane perpendicular to the X-Y plane; and, (C) a controller operatively coupled to the first joint and the second joint, the controller including a first control configured to direct repositioning of at least one of the first member and the second member, and a second control configured to direct repositioning of at least one of the third member and the fourth member.
1 . A medical instrument controller comprising:
a hand-held control including a plurality of controls at least partially received within a housing;
the plurality of controls comprises:
a first wheel rotationally repositionable with respect to the housing, the first wheel is operatively coupled to a first wire extending beyond the housing so that rotation of the first wheel in a first direction increases a length of the first wire within the housing, and rotation of the first wheel in a second direction, opposite the first direction, decreases the length of the first wire within the housing;
a second wheel rotationally repositionable with respect to the housing, the second wheel is operatively coupled to a second wire extending beyond the housing so that rotation of the second wheel in a first bearing increases a length of the second wire within the housing, and rotation of the second wheel in a second bearing, opposite the first bearing, decreases the length of the second wire within the housing; and,
a handle repositionably mounted to the housing, the handle being operatively coupled to a third wire extending beyond the housing so that repositioning the repositionable handle with respect to the housing causes repositioning of the third wire with respect to the housing;
wherein each of the first wheel and the second wheel are predominantly situated within a common interior cavity delineated by the housing; and,
wherein the handle includes an arcuate shape configured to match an arcuate shape of an underside of the housing.
2 . A medical instrument controller comprising:
a hand-held control including a plurality of controls at least partially received within a housing;
the plurality of controls comprises:
a first wheel rotationally repositionable with respect to the housing, the first wheel is operatively coupled to a first wire extending beyond the housing so that rotation of the first wheel in a first direction increases a length of the first wire within the housing, and rotation of the first wheel in a second direction, opposite the first direction, decreases the length of the first wire within the housing;
a second wheel rotationally repositionable with respect to the housing, the second wheel is operatively coupled to a second wire extending beyond the housing so that rotation of the second wheel in a first bearing increases a length of the second wire within the housing, and rotation of the second wheel in a second bearing, opposite the first bearing, decreases the length of the second wire within the housing; and,
a handle repositionably mounted to the housing, the handle being operatively coupled to a third wire extending beyond the housing so that repositioning the repositionable handle with respect to the housing causes repositioning of the third wire with respect to the housing;
wherein the first wheel and the second wheel are rotationally repositionable around a common axis;
wherein the first wheel is configured to rotate independent of the second wheel.
