Abstract
A support stand (10) for a minimally invasive surgical instrument (12), comprising first and second scissored arms (22 and 24) intersecting each other at an arm pivot (54); and an instrument holder (20) for holding the minimally invasive surgical instrument (12), the instrument holder (20) being supported by the first and second arms (22 and 24); wherein the first and second arms (22 and 24) are selectively pivotable relative to each other about the arm pivot (54) and wherein the arm pivot (54) is selectively movable along the first and second arms (22 and 24).
Core Innovation
The invention is a support stand for a minimally invasive surgical instrument. First and second arms intersect at an arm pivot and support an instrument holder. The arms are selectively pivotable relative to each other, and the arm pivot is selectively movable along the arms, allowing the holder’s position and orientation relative to the base to be adjusted.
The arm pivot has locked, rotatable, and free-moving configurations. In the locked configuration, the arms are pivotally fixed relative to each other and the pivot is fixed along them; in the other configurations, the arms can pivot, with the pivot either fixed or movable along the arms. The problem being solved is not explicitly described in patent.
Claims Coverage
The two independent claims cover support stands with intersecting arms, an instrument holder, and an arm pivot configurable for locking, pivoting, and movement along the arms. Two inventive features distinguish the independent claims by the pivot’s location in the rotatable configuration.
Support stand with a pivot fixed along both arms
The first and second arms support an instrument holder and are selectively pivotable relative to each other about an arm pivot that is selectively movable along both arms. In the locked configuration, the arms are pivotally fixed relative to each other and the pivot is fixed along the arms; in the rotatable configuration, the arms are pivotable and the pivot is fixed along both arms; in the free moving configuration, the arms are pivotable and the pivot is movable along both arms.
Support stand with a pivot fixed along one arm
The first and second arms support an instrument holder and are selectively pivotable relative to each other about an arm pivot that is selectively movable along both arms. In the locked configuration, the arms are pivotally fixed relative to each other and the pivot is fixed along the arms; in the rotatable configuration, the arms are pivotable and the pivot is fixed along one arm; in the free moving configuration, the arms are pivotable and the pivot is movable along both arms.
Both independent claims cover a support stand with a holder supported by intersecting arms and an arm pivot with locked, rotatable, and free moving configurations. They differ in whether the pivot is fixed along both arms or one arm in the rotatable configuration.
