Abstract
A surgical instrument comprising a node rotatably mounted within a restraining structure at the distal end of a shaft. The node can be rotated allowing manipulation and orientation of a surgical tool extending from the node at the distal end of the shaft through control remote from the distal end of the shaft. Cameras may also be located at the distal end of the shaft allowing stereoscopic imaging to be conveyed to an operator.
Claims21
An instrument comprising a node rotatably mounted within a restraining structure at the distal end of a shaft, wherein a surgical tool extends from the node and the node can be rotated allowing manipulation and orientation of the surgical tool at the distal end of the shaft through control remote from the distal end of the shaft, and comprising a channel for the removal of plaque from a blood vessel, and at least one camera, and further comprising a tool for removal of plaque from a blood vessel.
An instrument comprising:
- (i) a node at the distal end of a first shaft, wherein a surgical tool can be inserted through the node allowing manipulation and orientation of the tool at the distal end of the first shaft through control remote from the distal end of the first shaft;
- (ii) a plurality of cameras located at the distal end of the first shaft positioned so that they can convey a stereoscopic image to an operator;
- (iii) a source of light or other electromagnetic radiation;
- and
- (iv) an inner second shaft connected to a balloon, which inner second shaft is extendable relative to the first shaft.
An instrument comprising a node at the distal end of a shaft, wherein a surgical tool can be inserted through the node and the node can be rotated allowing manipulation and orientation of the surgical tool at the distal end of the shaft through control remote from the distal end of the shaft, and comprising a channel for the deployment of an intraluminally deployed device, and including at least one intraluminally deployed device.
