Patent number: 11950966Abstract: Surgical tools and assemblies are employed for use in minimally invasive surgical (MIS) procedures. A surgical tool assembly includes a handle assembly and a frame assembly. The handle assembly and frame assembly are designed and constructed to have an articulation input joint and a grounding joint between them. A pitch rotational degree of freedom and a yaw rotational degree of freedom are provided by way of the articulation input joint. The handle assembly is translationally constrained relative to the frame assembly by way of the grounding joint. Intermediate bodies and joints can be provided in certain surgical tool assemblies and architectures.Type: GrantFiled: June 2, 2021Date of Patent: April 9, 2024Assignee: FlexDex, Inc.Inventors: Zachary R. Zimmerman, Gregory Brian Bowles, Deepak Sharma, Matthew P. Weber, Christopher Paul Huang Shu, James Duncan Geiger

Publication number: 20220175441Abstract: Many embodiments of a surgical tool are set forth herein that can be employed for use in minimally invasive surgical procedures and in remote access surgical procedures. The surgical tool has multiple bodies with one or more detachable structural interfaces that can be established between one or more pairs of the bodies. Certain locks, interlocks, and/or joints can be present in the surgical tool and among the bodies in various embodiments in order to provide certain functionalities during use.Type: ApplicationFiled: September 17, 2021Publication date: June 9, 2022Inventors: Matthew P. Weber, Deepak Sharma, Zachary Zimmerman, Shorya Awtar, James Duncan Geiger, James Michael Licht, Srinivas Bidare, Pradeep Akkineni

Publication number: 20210038865Abstract: An example roll handle assembly includes a handle body, a roll body, a closure body, and a shuttle body. The roll body is coupled to the handle body and has a rotational degree of freedom about a roll axis relative to the handle body. The roll body is translationally constrained along the roll axis relative to the handle body. The closure body is coupled to the handle body and has one or more degrees of freedom of motion relative to the handle body. The shuttle body is coupled to the roll body and the closure body, and has a translational degree of freedom along the roll axis relative to the roll body. The shuttle body is rotationally constrained about the roll axis relative to the roll body, and has a rotational degree of freedom about the roll axis relative to the closure body.Type: ApplicationFiled: July 13, 2020Publication date: February 11, 2021Inventors: Deepak Sharma, Gregory Brian Bowles, James Michael Licht, Zachary Zimmerman, Shorya Awtar, James Duncan Geiger

Publication number: 20180289384Abstract: Devices having a handle that provides unlimited roll to an end-effector at the distal end of the device. For example, described herein are medical devices that have an elongate tool frame, an end-effector, and a handle that includes: a first portion, a second portion that rolls relative to the first portion, a push rod within the first portion connected to a control input, and a shuttle body within the second portion that rotates with the second portion but is axially driven by the push rod when the user actuates the control input. The device may include a proximal wrist/forearm attachment allowing one or more degrees of freedom in pitch, yaw or roll about the user's arm. The handle may articulate relative to the tool frame, and this articulation may be transmitted to the end-effector. The end-effector may be a jaw assembly.Type: ApplicationFiled: April 2, 2018Publication date: October 11, 2018Inventors: Gregory Brian BOWLES, James Michael LICHT, Zachary ZIMMERMAN, Shorya AWTAR, Deepak SHARMA, James Duncan GEIGER

Publication number: 20180049842Abstract: Apparatuses and methods for attaching a minimal access tool to a user's boy (e.g., wrist or forearm) so that movements of the user's forearm, wrist, hand and fingers can control movements at a distal end of the minimal access tool. In particular, described herein are forearm attachment devices (which may be used with or integrated into) a minimal access tool including a cuff configured to secure to the user's forearm and a coupling joint configured to connect the cuff to the frame so that the cuff may move relative to the frame with between 1 and 4 degrees of freedom.Type: ApplicationFiled: October 16, 2017Publication date: February 22, 2018Inventors: Gregory Brian BOWLES, James Duncan GEIGER, James Michael LICHT, Shorya AWTAR, Zachary ZIMMERMAN, Deepak SHARMA
