Friction Transmission With Axial Loading And A Radiolucent Surgical Needle Driver

View page
US Patent:
6400979, Jun 4, 2002
Filed:
Feb 20, 1998
Appl. No.:
09/026669
Inventors:
Dan Stoianovici - Baltimore MD
Louis R. Kavoussi - Lutherville MD
Louis L. Whitcomb - Baltimore MD
Russell H. Taylor - Severna Park MD
Jeffrey A. Cadeddu - Baltimore MD
Roger D. Demaree - Sykesville MD
Stephen A. Basile - Gaithersburg MD
Assignee:
Johns Hopkins University - Baltimore MD
International Classification:
A61B 500
US Classification:
600427, 600429, 600567
Abstract:
A method for performing radiological-image-guided percutaneous surgery with a system which includes a radiological image generating device for generating an image of a target anatomy of a patient, and a needle insertion mechanism disposed adjacent the image generating device and having a needle adapted to be inserted into the patient. The method includes the steps of: determining a needle trajectory of the needle by positioning the image generating device for aligning, in the image generated by the image generating device, a desired skin insertion site of the patient with a target region of the target anatomy; locking the needle in a direction of the needle trajectory; and repositioning the image generating device to obtain a lateral view of the needle trajectory for viewing an insertion depth and path of the needle during its insertion into the patient. Moreover, a motion transmission mechanism includes an output shaft and an output shaft driver which has two rotational components having respective contact faces between which the output shaft is pressed for frictional engagement therewith. The frictional engagement creates a force between the output shaft and the rotational components which is parallel to the rotational axis of the rotational components for allowing the rotational components to impart a translational motion to the output shaft by virtue of their rotational motion.

US Classification:
606129, 600566, 600568
Abstract:
Featured is an apparatus that places or locates a proximal end portion of a penetrating member in a target area of a body. Such an apparatus or needle driver is particularly suited for locating a percutaneous needle in a soft tissue target area of a body particularly a body having inhomogeneous soft tissues. The apparatus includes a first arm that is configured and arranged so as to support a distal portion of the penetrating member and a first drive mechanism that is coupled to the first arm. The first drive mechanism is configured and arranged to move or translate the first arm from an initial position to any of a number of other positions that are spaced from the initial position and correspondingly translate the proximal end portion of the penetrating member. In another embodiment, the first arm also rotatably supports the penetrating member and the apparatus further includes a second drive mechanism coupled to the penetrating member distal portion and which is configured an arranged to rotate the penetrating member about the translational axis.

US Patent:
7621229, Nov 24, 2009
Filed:
Apr 17, 2008
Appl. No.:
12/148226
Inventors:
Andy Bowen - Woods Hole MA, US
Louis Whitcomb - Baltimore MD, US
Dana R. Yoerger - North Falmouth MA, US
Robert McCabe - North Falmouth MA, US
Assignee:
Woods Hole Oceanographic Institution - Woods Hole MA
International Classification:
B63B 21/66
US Classification:
114244, 114312, 114322
Abstract:
Systems for tethering an underwater vehicles using a low strength optical fiber tether. The tether system includes, a mechanical fuse that prevents a high load from acting on and severing the tether that is attached to the underwater vehicle, thus allowing use of far smaller cables than typically used. Upon separation of the fuse, a cable payout system pays out an optical fiber that keeps the underwater vehicle, typically a robotic craft, in communication with the surface vessel. The relatively light weight glass fiber may be reinforced and extended to lengths greater than 40 km allowing deep-sea exploration at depths up to 11,000 m.

International Classification:
A61B 5/00
US Classification:
600411, 600427, 600439, 606 1, 606 41
Abstract:
A device, system, and method for entering a medical device such as a needle into the body inside a medical imager such as a MRI scanner, CT, X-ray fluoroscopy, and ultrasound imaging, from within a body cavity (such as the rectum, vagina, or laparoscopically accessed cavity). A three degree-of-freedom mechanical device translates and rotates inside the cavity and enters a needle into the body, and steers the needle to a target point selected by the user. The device is guided by real-time images from the medical imager. Networked computers process the medical images and enable the clinician to control the motion of the mechanical device that is operated within the imager, outside of the imager or remotely from outside the imager.
