US 2022/0022988 A1 · USER INTERFACE DEVICE HAVING FINGER CLUTCH

Abstract

User interface devices for manipulating a robotic surgical tool in a surgical robotic system are described. A user interface device can include a device housing having a gripping surface symmetrically disposed about a central axis. The gripping surface can include a surface of revolution about the central axis. A tracking sensor can be mounted within the device housing to generate spatial state signals in response to movement of the device housing. The spatial state signals can be used to control motion of robotic system actuators. A finger clutch can be disposed at an end of the device housing, and can generate a clutch signal in response to a touch by a user. The clutch signal can be used to pause the motion of the robotic system actuators. Other embodiments are also described and claimed.

Dependent claims

A user interface device for manipulating a surgical tool in a surgical robotic system, comprising:

a device housing having a gripping surface, wherein the gripping surface is radially symmetric about an axis of symmetry;
a tracking sensor in the device housing, wherein the tracking sensor is configured to generate a plurality of spatial state signals tracking movement of the device housing in six degrees of freedom to control motion of the surgical tool;
and
a finger clutch having a touch-sensitive surface facing radially outward from the axis of symmetry, wherein the finger clutch is configured to, when touched, generate a clutch signal to cause one or more processors of the surgical robotic system to pause motion of the surgical tool regardless of the plurality of spatial state signals.
