Jason Alan Hill - Loveland OH, US

Assignee:

Cilag GmbH International - Zug

International Classification:

A61B 34/00
A61B 34/37

Abstract:

A robotic surgical tool includes an elongate shaft extendable through a handle, a drive cable extending along a portion of the shaft, and an actuation system housed within the handle and including an input stack having first and second ends. The input stack includes a drive input arranged at the first end, and an accumulator arranged between the first and second ends and including a differential body defining upper and lower redirect surfaces, and a redirect feature offset from the upper and lower redirect surfaces, wherein the drive cable is threaded through the upper and lower redirect surfaces and the redirect feature, and wherein actuating the actuation system rotates the input stack and thereby acts on the drive cable to cause one or more operations of the surgical tool.

B25J 9/10
B25J 15/00
B25J 15/04

Abstract:

A robotic surgical tool includes a handle having a plurality of drive inputs rotatably mounted thereto, an elongate shaft extending through the handle and having an end effector arranged at a distal end thereof, and a plurality of drive members extending along the shaft to the end effector. A plurality of input stacks are arranged within the handle and operatively coupled to the plurality of drive inputs such that actuation of the plurality of drive inputs rotates the plurality of input stacks. Each input stack includes a drive member engagement device that locates and captures a corresponding one of the plurality of drive members at the handle upon rotation of the input stack.

International Classification:

A61B 34/30
A61B 34/00
A61B 17/32

Abstract:

A robotic surgical tool includes a handle providing a first drive input and a second drive input, an elongate shaft extendable through the handle and having an end effector arranged at a distal end thereof, and a rack extending along a portion of the shaft and operatively coupled to a knife located at the end effector. Actuation of the first drive input transitions the rack between a locked configuration, where the rack is locked to the shaft, and a released configuration, where the rack is released from the shaft. Actuation of the second drive input with the rack in the locked configuration drives the rack and causes z-axis translation of the shaft through the handle. Actuation of the second drive input with the rack in the released configuration drives the rack relative to the shaft and thereby advances or retracts the knife at the end effector.

A61B 17/072
A61B 17/29

Abstract:

A robotic surgical tool includes an elongate shaft, an end effector arranged at a distal end of the shaft and including opposing first and second jaws, an articulable wrist that interposes the end effector and the distal end, the wrist including an articulation joint pivotable about an axis and a linkage mounted to the first and second jaws, a distal wedge positioned distal to the articulation joint and within a central portion of the wrist, and an electrical conductor extending through the wrist and to an electrode located at the end effector, wherein the distal wedge guides the electrical conductor to the electrode.

Assignee:

Ethicon LLC - Guaynabo PR

International Classification:

A61B 34/30

Abstract:

A robotic surgical tool includes an elongate shaft, an end effector arranged at a distal end of the shaft and including opposing first and second jaws, and an articulable wrist that interposes the end effector and the distal end, the wrist including a linkage providing one or more lateral arms receivable within a corresponding one or more grooves defined in the first and second jaws, wherein mounting the linkage to the first and second jaws at the corresponding one or more groove generates a jaw pivot where the first and second jaws pivot between open and closed positions.

Abstract:

A robotic surgical tool includes an elongate shaft extendable through a handle that provides a drive input, an actuation system housed within the handle and operatively coupled to the drive input such that actuation of the drive input operates the actuation system, a rocker bar system arranged at a proximal end of the shaft and actuatable to articulate an end effector at a distal end of the shaft, and first and second drive cables extending along a portion of the shaft, each drive cable having a proximal end anchored to the shaft proximal to the handle and a distal end anchored to the shaft distal to the handle, wherein the drive cables are threaded through portions of the actuation and rocker bar systems such that operation of the actuation system acts on the drive cables and thereby actuates the rocker bar system to articulate the end effector.
