  • Patent number: 8052609
    Abstract: A connectorized ultrasound probe includes a distal section that is configured for insertion into a patient's body and a proximal section configured to interface the distal section with an ultrasound system. The distal section is easily attachable and detachable from the proximal section using at least one set of connectors. When connected, a user-operated actuator located on the proximal section controls the bending of the distal section, and the ultrasound system sends driving signals to and receives return signals from the ultrasound transducer via the proximal section. This arrangement is particularly advantageous for long term monitoring, because the disconnectability of the proximal section makes it possible to leave the distal section in place in the patient for longer periods of time without undue discomfort. In some preferred embodiments, the mechanical interface is made before the electrical interface when the distal section is connected to the proximal section.

    Abstract: Disclosed herein is a portable endoscope and kit for performing multiple medical procedures. The portable endoscope comprises a detachable operator control section assembly and one of multiple detachable and interchangeable flexible insertion shaft assemblies with a flexible distal end. The proximal end of a detachable and interchangeable flexible insertion shaft assembly is detachably connected to the detachable operator control section assembly. The detachable and interchangeable flexible insertion shaft assembly accommodates principal cable wires, proxy cable wires, an optical imaging system, and an illumination system. An internal cable wire control system integrated with the detachable operator control section assembly utilizes an adaptable drive transmission system for controlling the orientation and angular position of the flexible distal end using the principal cable wires or the proxy cable wires. The proxy cable wires may be engaged in an event of failure of the principal cable wires.

  • Patent number: 7510524
    Abstract: The illumination system is a cannula comprising a transparent or semitransparent material capable of carrying light from the proximal end of the cannula to the distal end of the cannula, thereby illuminating a surgical field. The surgical field is thus illuminated through components that do not occupy space that may otherwise by used for optics and or surgical tools. The illumination source may be optically coupled with the cannula at any appropriate location. The cannula comprises a sterilizable polymer which functions as a waveguide. A waveguide is a material medium that confines and guides light. When in use, the light source connected to the hub provides light which may be guided to the distal end of the cannula or any other suitable location. Thus, the sheath provides structure-guided illumination resulting in the illumination of the surgical site.
