Inventors:

- Brighton MI, US
Zachary R. Zimmerman - Northville MI, US
Christopher Paul Huang Shu - Ann Arbor MI, US

International Classification:

A61B 17/29

Abstract:

Surgical tools and assemblies are employed for use in minimally invasive surgical (MIS) procedures. A handheld surgical tool assembly includes a handle assembly and a frame assembly, among other possible components. Intermediate bodies and joints are provided in certain handheld surgical tool assemblies and architectures. A yaw rotational degree of freedom is furnished between certain intermediate bodies, and a pitch rotational degree of freedom is furnished between certain intermediate bodies. Amid use, a mechanical advantage generated about the yaw rotational degree of freedom is unequal to a mechanical advantage generated about the pitch rotational degree of freedom.

Abstract:

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.
