A Novel Discretely Actuated Steerable Probe for Percutaneous Procedures
نویسندگان
چکیده
Innovative Technology To improve steering precision in needles as well as hollow, flexible cannula, researchers at the University of Maryland have introduced discrete actuators along the length of the probing device. The probe (needle or cannula) can be bent in the required direction in real-time, allowing more areas of the body tissues to be targeted with greater accuracy. A shape memory alloy (SMA) based actuator would be well-suited for the device, with the potential for multiple actuators used at different locations along the probe. Electro-active polymer actuators might also be used. Probe steering can be done in real-time under several imaging modalities, including, but not limited to, Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and ultrasound imaging.

Design and Implementation of a New Discretely-Actuated Manipulator
This paper presents a new 3-D design of a discretely-actuated robot manipulator powered by binary actuators. Binary actuators have two stable states, which are, for example, closed (0) and open (1). Major benefits of this kind of discretely-actuated manipulator are repeatability, relatively low cost, and no need for feedback control. In addition, hyper-redundancy allows tasks to be performed ev...
متن کاملNumerical convolution on the Euclidean group with applications to workspace generation
In this work, the concept of a convolution product of real-valued functions on the Special Euclidean group, SE(D) (which describes all rigid body motions in D-dimensional Euclidean space), is applied to the determination of workspaces of discretely actuated manipulators. These manipulators have a finite number of joint states. If a discretely actuated manipulator consists of P actuated modules,...
متن کاملLaparoscopic Manipulation of a Probe-based Confocal Laser Endomicroscope Using a Steerable Intravascular Catheter
Probe-based confocal laser endomicroscopy is an emerging imaging modality that enables visualization of histologic details during endoscopy and surgery. A method of guiding the probe with millimeter accuracy is required to enable imaging in all regions of the abdomen accessed during laparoscopy. On the basis of a porcine model of laparoscopic liver resection, we report our experience of using a...
متن کاملA New Inverse Kinematic Algorithm for Discretely Actuated Hyper-redundant Manipulators
The term discretely actuated hyperredundant manipulator is applied to a kind of manipulators which consists of serially connected modules. Such modules are composed of discretely actuated joints having finite stable states. Since the previous studies have rarely offered satisfactory results regarding the problem of inverse kinematics of discretely actuated hyper-redundant manipulators, the pres...
متن کاملInverse Kinematics of Discretely Actuated Hyper - RedundantManipulators Using Workspace
Hyper-redundant manipulators present an alternative to conventional 6 DOF manipulators for inspection , space, and medical applications. The additional degrees of freedom facilitate obstacle avoidance and allow tasks to be performed even if some of the actu-ators fail. In this paper we consider hyper-redundant manipulators that are actuated discretely, e.g. using two-state actuators or motors w...
