摘要

A medical system generally comprises a camera head, a beam, and a guide sheath. The camera head is connected to the beam which is bendable in a first direction and resists bending in a second direction opposite the first direction. The guide sheath slidably receives the beam, the beam extending through a distal end of the guide sheath such that the camera head projects from the distal end of the guide sheath. The guide sheath includes first and second sheath portions, and in an operative configuration the first sheath portion is angled relative to the second sheath portion to define a first bend. The beam is oriented relative to the guide sheath such that, as the beam is slid relative to guide sheath, the beam bends in the first direction through the first bend, and a projecting portion of the beam resists bending in the second direction.

主权项

1. A medical system for use intracorporeally to assist in surgical procedures beneath a tissue layer, the system comprising:
a camera; a beam having a distal end attached to the camera, the beam including a plurality of links connected together for relative rotation between adjacent links, the links structured such that, when adjacent links are in a straight linear configuration, the adjacent links may rotate relative to each other in a first direction and cannot substantially rotate relative to each other in a second direction opposite the first direction; a guide sheath slidably receiving the beam, the beam extending through a distal end of the guide sheath such that the camera projects from the distal end of the guide sheath, the guide sheath including a first sheath portion defining a first axis and a second sheath portion defining a second axis, the guide sheath having an operative configuration wherein the first sheath portion is angled relative to the second sheath portion to define a first bend; and the beam oriented relative to the guide sheath such that, as the beam is slid relative to guide sheath, the beam bends in the first direction through the first bend, and a projecting portion of the beam projecting from the distal end of the guide sheath resists bending in the second direction.
