US Patent:

46325018, Dec 30, 1986

Filed:

Feb 16, 1984

Appl. No.:

6/580657

Inventors:

Paul E. Glynn - Braintree MA

Assignee:

General Scanning, Inc. - Watertown MA

International Classification:

G02B 2610

US Classification:

350 66

Abstract:

A resonant electromechanical oscillator which includes a base portion, a driven portion, a cantilevered sheet-form flexural suspension which spaces the driven portion from the base portion for oscillation about an axis in the plane of the sheet-form suspension, and an electromagnetic drive which includes cooperating portions on the base and driven portions for oscillating the driven portion at a resonant frequency. The ends of the sheet-form suspension are coupled to the base and driven portions with at least one end coupling being adjustable to select the resonant frequency of the oscillator by changing the effective length of the sheet suspension. Fixed surfaces on the base portion limit angular excursion of the driven portion and limit buckling distortion of the sheet-form suspension. Preferred embodiments of the oscillator have a driven portion with a mass in the range of two to ten grams, and withstand impact loads of at least five hundred g's. In particular, a rugged resonant scanner, capable of use in a portable device is shown.

Abstract:

Radiation detection probes for use with remote surgical robots are described. Probes may include a radiation detector (e.g., scintillator) that emits a signal (e.g., light) upon exposure to ionizing radiation originating from a radionuclide located within the body of a patient. In some embodiments, an optical fiber cable extending from a scintillator may transmit the signal to a photomultiplier and/or other signal processor, so as to ultimately provide an indication to an observer as to the potential presence/location of the radionuclide. The radiation detector may be located at a distal end of the probe, arranged to be inserted within the body of a patient during surgery, without any electrical component(s). That is, any electrical component(s) of or connected to the probe remain outside the body of the patient during surgery. The radiation detector may further be able to be inserted within the lumen of a relatively small trocar, e.g., less than 16 mm in diameter, less than 12 mm in diameter, or less than 10 mm in diameter.
