Endoscope assemblies having working channels with reduced bending and stretching resistance
InactiveUS7056284B2Reduce bending and stretching resistanceReduce tensionSurgeryVaccination/ovulation diagnosticsAxial forceEngineering
Apparatus and methods for endoscope assemblies having working channels with reduced bending and stretching resistance are disclosed. In one embodiment, an endoscope assembly includes a sheath having a body portion adapted to at least partially encapsulate an endoscopic insertion tube, and a working channel attached to the body portion and extending along at least a portion of the body portion. The working channel includes a component for reducing the resistance of the assembly to bending and stretching. In alternate aspects, the working channel may include a cut, a gap, a sliding portion, or an expansion section. Endoscope assemblies having a working channel in accordance with the invention advantageously reduce the articulation and stretching resistance of the assembly during articulation of the endoscope assembly. Also, because the axial forces (tension and compression) within the working channel are reduced, the working channel can be fabricated out of a relatively hard, inelastic material, thereby reducing the friction within the working channel and improving the physician's ability to perform a medical procedure.

A portable augmented motor-sensory interface (“PAMI”) system for “tele-controlled” surgery includes a PAMI tele-controller and a portable PAMI medical field unit positioned at a different, distant location and configured for wireless communications with the tele-controller. (“Tele-control” refers to electronically translating and / or transmitting a physician's actions over a long distance.) The field unit has a surgical module, including robotic effectors / arms, configured for carrying out medical procedures, and a video sensor boom for electronically viewing a wound site. The tele-controller has a user interface with input controls and a display that outputs sensory information relating to the patient and field unit. For treating a patient, the field unit is deployed next to the patient and a communications link is established to the tele-controller. A physician at the tele-controller receives sensory input from the field unit through the user interface display, and manipulates the input controls for tele-controlling the surgical module.

Method for tracking and reporting usage events to determine when preventive maintenance is due for a medical robotic system
A medical robotic system comprises a number of components that may be monitored to determine their preventive maintenance needs by recording usage-related information for the monitored components into associated non-volatile memories. When usage of the component exceeds a specified usage threshold, the system displays a warning message on its display screen to have preventive maintenance performed for the component. If the usage continues without such maintenance and exceeds a higher usage threshold, the system displays an error message on its display screen and the system transitions into an error state during which medical procedures are not allowed to be performed. The usage-related information may also be communicated to a remote computer which gathers and processes usage-related information from a number of medical robotic systems to estimate resource requirements for timely performing preventive maintenance on the medical robotic systems, and anticipated service revenues from such maintenance.

Medical robotic system with coupled control modes
In a coupled control mode, the surgeon directly controls movement of an associated slave manipulator with an input device while indirectly controlling movement of one or more non-associated slave manipulators, in response to commanded motion of the directly controlled slave manipulator, to achieve a secondary objective. By automatically performing secondary tasks through coupled control modes, the system's usability is enhanced by reducing the surgeon's need to switch to another direct mode to manually achieve the desired secondary objective. Thus, coupled control modes allow the surgeon to better focus on performing medical procedures and to pay less attention to managing the system.

InactiveUS6939346B2Finer granularity of controlMinimize overshootThermometers using electric/magnetic elementsUsing electrical meansThermal energyMedicine
A thermal energy controller system useful in medical procedures includes a controller coupled to a probe, and a thermal element to vary probe temperature. The controller includes memory storing a non-continuous algorithm that permits user-selectable settings for various probe types such that controller operation is self-modifying in response to the selected probe setting. Probe output power Pout is constant in one mode to rapidly enable probe temperature to come within a threshold of a target temperature. The controller can then vary Pout dynamically using a proportional-integral-derivative (PID) algorithm Pout=Kp·P+Ki·I+Kd·D, where feedback loop coefficients Kp, Ki, Kd can vary dynamically depending upon magnitude of an error function e(t) representing the difference between a user-set desired target temperature and sensed probe temperature. Advantageously, target temperature can be rapidly attained without overshoot, allowing the probe system to be especially effective in arthroscopic tissue treatment.
