CROSSTALK REDUCING HANDLE FOR SURGICAL ARTICULATED INSTRUMENTS

摘要

The present invention relates to a bodily invasive steerable device (100) having a proximal (201) and distal (205) end comprising a steering mechanism (50) having a proximal bending part (202), a distal bending part (204), and an intermediate part (203) disposed between the proximal bending part (202) and the distal bending part (204) configured mechanically to transmit forces applied at the proximal end (201) to the distal end (205). The steering is mechanism configured such that the distal bending part (204) moves responsive to movements of the proximal bending part (202). The device also comprises a handle (206) coupled to the proximal bending part (202) to effect manual bending. The handle (206) comprises at least one grip member (210) that extends distally (205), at least over the proximal terminal end (171) of the proximal bending part (202).

1. A bodily-invasive steerable device (100) having a proximal (201) and distal (205) end comprising:
i) a steering mechanism (50) having
a proximal bending part (202),a distal bending part (204), andan intermediate part (203) disposed between the proximal bending part (202) and the distal bending part (204) configured mechanically to transmit forces applied at the proximal end (201) to the distal end (205), the steering mechanism configured such that the distal bending pa (204) moves responsive to movements of the proximal bending part (202), and ii) a handle (206) coupled to the proximal bending part (202) to effect manual bending; wherein
the handle (206) comprises at least one grip member (210) that extends distally (205), at least over the proximal terminal end (171) of the proximal bending part (202),the distal bending part (204) is configured for movement in at least two different intersecting planes, andthe device (100) is further provided with an end effector at the distal end of the distal bending part (204) wherein the steering mechanism (50) is configured such that the end effector is rotationally fixed in relation to the distal bending part (204), and the end effector is rotatable when the distal bending part (204) is in a bent position, by a complementary rotation of the proximal bending part (202).
