Featured is a robot and a needle delivery apparatus. Such a robot comprises a plurality of actuators coupled to control locating any of number of intervention specific medical devices such as intervention specific needle injectors. Such a robot is usable with image guided interventions using any of a number of types of medical imaging devices or apparatuses including MRI. The end-effector can include an automated low needle delivery apparatus that is configured for dose radiation seed brachytherapy injection. Also featured is an automated seed magazine for delivering seeds to such an needle delivery apparatus adapted for brachytherapy seed injection.

A stepper motor suitable for use in a medical imaging environment has (a) a cylindrical central gear having an external surface with circumferentially distributed and radially directed teeth, (b) a shaft for mounting the central gear such that it is constrained to move in rotational motion about its centerline, (c) a cylindrical hoop gear having a bore with an internal surface having circumferentially distributed and radially directed teeth, (d) level arm crank mechanisms for mounting the hoop gear such that it is constrained to move in translational-circular motion about the central gear's centerline, wherein this central gear is further configured to fit within the hoop gear's bore in such a manner that a plurality of the central gear and hoop gear teeth intermesh and cooperate so that the planetary movement of the hoop gear causes the central gear to rotate, and (e) piston mechanisms for applying a fluid pressure driven force to specified points on the hoop gear so as to cause its movement.

Pneumatic stepper motor

A method for remotely monitoring a patient. The method includes generating and transmitting input commands to the robot from a remote station. The remote station may include a personal computer that is operated by a doctor. The input commands can move the robot so that a video image and sounds of the patient can be captured by a robot camera and microphone, respectively, and transmitted back to the remote station. The robot may also have a monitor and a speaker to allow for two-way videoconferencing between the patient and a doctor at the remote station. The robot can move from room to room so that a doctor can make 'patient rounds' within a medical facility. The system thus allows a doctor visit patients from a remote location, thereby improving the frequency of visits and the quality of medical care. REEXAMINATION RESULTS The questions raised in reexamination proceeding No. 90/012,069, filed Dec. 22, 2011, have been considered, and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e) forreexaminations, or the reexamination certificate required by 35 U.S.C. 316 as provided in 37 CFR 1.997(e) forreexaminations.

Apparatus and method for patient rounding with a remote controlled robot

A training and/or evaluating device is provided particularly useful in performing laparoscopic procedures, radiological procedures, and precise surgeries that simulates the structure and dynamic motion of the corresponding anatomical structure on which the procedure takes place. The device includes an outer housing, which may be designed to mimic the body wall, in which one or more organs are located. Motion of the organ(s), as a result of respiration, pulmonary action, circulation, digestion and other factors present in a live body, is simulated in the device so as to provide accurate dynamic motion of the organs during a procedure.

Device and method for medical training and evaluation

A system and method for CT guided instrument targeting including a radiolucent instrument driver; a robot and a control box. The robot includes a robotic module that positions the radiolucent driver about two directions coincident a predetermined point. The control device is connected to the robot and the radiolucent instrument driver. The control driver sends a robot control signal to the robot that causes the robotic module to place the radiolucent instrument driver in a desired orientation with respect to the predetermined point. After the radiolucent instrument driver is in the desired orientation, the control device sends a driver control signal to the radiolucent instrument driver that causes the radiolucent driver to insert a medical instrument or device through the predetermined point to a location proximate a target point in a patient.

Robot for computed tomography interventions

A method and system for laser based instrument registration. The system includes an operating table coupled with a robot holding an instrument, and CT scanner. The CT scanner has first and second laser markers. The method includes moving the robot to align the instrument in a first position wherein a tip of the instrument is disposed within a first laser plane created by the first laser marker. Then, the robot moves the instrument to a second position wherein the entire instrument is disposed within the first laser plane. Coordinate data of the robot in the second position is obtained. Image data of a first slice is obtained from the CT scanner. The registration data is calculated based on the coordinate data and the image data.

System and method for laser based computed tomography and magnetic resonance registration

A method for remotely monitoring a patient. The method includes generating and transmitting input commands to the robot from a remote station. The remote station may include a personal computer that is operated by a doctor. The input commands can move the robot so that a video image and sounds of the patient can be captured by a robot camera and microphone, respectively, and transmitted back to the remote station. The robot may also have a monitor and a speaker to allow for two-way videoconferencing between the patient and a doctor at the remote station.

A motor suitable for use in a medical imaging environment has (a) a cylindrical outer gear having a bore with a centerline and an internal surface with circumferentially distributed and radially directed teeth, (b) a means for mounting this outer gear such that it is constrained to move in rotational motion about its centerline, (c) a cylindrical planetary gear having a bore and an external surface having circumferentially distributed and radially directed teeth, (d) a means located within the planetary gear bore for applying a fluid pressure driven force to cause it to move in translational-circular motion about the outer gear's centerline, and (e) wherein the teeth of these gears are configured so as to cooperate such that the translational-circular motion of the planetary gear causes the rotational movement of the outer gear.

Planetary motor

A motor suitable for use in a medical imaging environment has (a) a centrally located means for actuating a radial wave, (b) a deformable flexspline having an inner surface and a toothed outer surface with a first specified number of teeth, and (c) a circular spline having a toothed inner surface with a second specified number of teeth which is different than the first specified number of teeth in the flexspline, wherein the actuation means is operable so that the action of its radial wave causes at least one of the flexspline teeth to engage at a point the toothed side of the circular spline in such a manner that an engagement point passes as a wave around the inner perimeter of the circular spine, with the movement of this engagement point causing the flexspline to rotate around its central axis.

A ball-worm transmission is provided which replaces the sliding friction of the classic worm mechanism with the rolling friction of spherical balls. The ball-worm transmission assembly includes a worm which defines a recirculation path, and a gear coupled to the worm via a plurality of spherical balls. The gear includes a plurality of teeth each having a thickness in a central plane of the gear and a lesser thickness towards both sides of the gear, so that a gap is defined between the teeth is larger towards both sides of the gear than in the central plane of the gear.

A remote center of motion robotic system including a base unit and a plurality of linking units. The base unit is rotatable about a first axis. The plurality of linking units are coupled with one another. At least two of the linking units are kept parallel to each another during motion. The plurality of linking units are coupled with that base unit at a first end. The plurality of linking units are rotatable about a second axis by changing an angle between each of the plurality of links.
