Filed:
Dec 7, 2001
Appl. No.:
10/013207

A61B 1708
US Classification:
606157, 606158, 606205
Abstract:
A clamp has a handle assembly, a gripping assembly having a pair of jaws that can be opened and closed to grip an element, and a shaft assembly. The shaft assembly has a flexible shaft having a proximal end that is operatively coupled to the handle assembly and a distal end that is operatively coupled to the gripping assembly. The shaft assembly also has a rigid element that can be placed in a first position where the rigid element supports the shaft in a manner where the shaft cannot be bent, and in a second position where the shaft can be bent.

Articulating Tool With Improved Tension Member System
US Patent:
7862554, Jan 4, 2011
Filed:
Apr 16, 2007
Appl. No.:
11/787608
Inventors:
David Elias Hegeman - San Jose CA, US

Assignee:
Intuitive Surgical Operations, Inc. - Sunnyvale CA
International Classification:
A61B 1/008
US Classification:
606 1, 600139
Abstract:
The invention provides surgical or diagnostic tools and associated methods that offer improved user control for operating remotely within regions of the body, and improved methods of assembling the tools. In some embodiments these tools include a proximally-located actuator for the operation of a distal end effector, as well as proximally-located actuators for articulational and rotational movements of the end effector. Control mechanisms and methods refine operator control of end effector actuation and of these articulational and rotational movements. The articulation mechanisms comprise pairs of links, one link distal and the other proximal, configured such that movement of a proximal link is transferred to the distal link by way of tension bearing members. Embodiments of the invention include a guide for such tension bearing members that facilitates assembly of the tool. Embodiments also include improved methods for attaching tension bearing members to the links.
Clamp Having Bendable Shaft
US Patent:
7901418, Mar 8, 2011
Filed:
Oct 4, 2003

International Classification:
A61B 17/08
US Classification:
606157
Abstract:
A clamp has a handle assembly, a gripping assembly having a pair of jaws that can be opened and closed to grip an element, and a shaft assembly. The shaft assembly has a flexible shaft having a proximal end that is operatively coupled to the handle assembly and a distal end that is operatively coupled to the gripping assembly. The shaft assembly also has a rigid element that can be placed in a first position where the rigid element supports the shaft in a manner where the shaft cannot be bent, and in a second position where the shaft can be bent.
Tool With Articulation Lock
US Patent:
8100824, Jan 24, 2012
Filed:
Apr 16, 2007
Appl. No.:
11/787543

Assignee:
Intuitive Surgical Operations, Inc. - Sunnyvale CA
International Classification:
A61B 1/00
US Classification:
600141, 600139, 600142, 600146
Abstract:
The invention provides surgical or diagnostic tools and associated methods that offer user control for operating remotely within regions of the body. These tools include a proximally-located actuator for the operation of a distal end effector, as well as proximally-located actuators for articulational and rotational movements of the end effector. Control mechanisms and methods refine operator control of end effector actuation and of these articulational and rotational movements. An articulation lock allows the fixing and releasing of both neutral and articulated configurations of the tool and of consequent placement of the end effector. The tool may also include other features. A multi-state ratchet for end effector actuation provides enablement-disablement options with tactile feedback. A force limiter mechanism protects the end effector and manipulated objects from the harm of potentially excessive force applied by the operator. A rotation lock provides for enablement and disablement of rotatability of the end effector.

International Classification:
A61B017/08
US Classification:
606/151000
Abstract:
A clamp has a handle assembly, a gripping assembly having a pair of jaws that can be opened and closed to grip an element, and a shaft assembly.
