Abstract:
A surgical apparatus includes a housing, a test port retainer, a pressure test chamber, and an image capture assembly. The housing includes a pressure test port. The test port retainer includes a test port retainer housing, a probe seal, and a liquid exclusion barrier. In one aspect, the test port retainer also includes a hydrophobic membrane mounted within the test port retainer housing. The pressure test chamber includes a manifold and a central tube. The first end of the central tube is affixed to the image capture assembly to form a pressure seal, and the second end of the central tube is coupled to the test port retainer so that the pressure test port communicates with the interior volume of the central tube through the test port retainer.
Abstract:
Vision systems on catheters, cannulas, or similar devices with guiding lumens include receptors distributed in annular areas around respective lumens. Each of the receptors has a field of view covering only a portion of an object environment, and the field of view of each of the receptors overlaps with at least one of the fields of view of the other receptors. A processing system can receive image data from the receptors of the vision systems and combine the image data to construct a visual representation of the object environment.
Abstract:
A connector system employs an electromechanical connector to connect to a complementary electromechanical connector on an electronic device in a medical system. A shroud surrounds the electromechanical connector and is conductive and shaped to provide a thermal contact to the electronic device. A shielded cable can be electrically coupled to the electromechanical connector and extending through an opening in the shroud, and an electromagnetic shield attaches to the shroud and surrounds the portion of the shielded cable extending from the shroud. A mechanical lock may be included with a spring to press the shroud against the electronic device when the mechanical lock engages the electronic device.
Abstract:
In one embodiment, an endoscopic camera for a robotic surgical system includes a stereo camera module mounted to a robotic arm of a patient side cart. The optical and electro-optic components of the camera module are hermetically sealed within a first housing. Signals from an electro-optic component travel through traces in a ceramic substrate forming one side of the hermetically sealed first housing. A second housing surrounds the first housing and optical fibers are dispersed between the housings to provide lighting in a body cavity. The camera module may be sterilized by an autoclave.

Abstract:
An endoscopic system includes a shaft comprising a proximal end portion and a distal end portion; a sensor system; a floating ground element electrically coupled to the sensor system; a power regulator electrically coupled to a power transmission line and to the floating ground element, the power regulator configured to convert ground-referenced power received from an earth ground referenced power source into floating ground element referenced power and to output the floating ground element referenced power through the power transmission line; and a circuit enclosure at least partially enclosing a transceiver circuit and the power regulator, the circuit enclosure being electrically coupled with the floating ground element.
Abstract:
An endoscopic system for sensing one or more characteristics at an environment of a worksite comprises a shaft comprising a proximal end portion and a distal end portion; an electrically active sensor system comprising a sensor positioned to sense at least one characteristic of an environment in which the distal end portion of the shaft is located; an electrical power transmission line electrically coupled to the sensor and extending along the shaft, the electrical power transmission line configured to transmit power to the sensor; and a floating ground element electrically isolated from an earth ground and operably coupled to the electrically active sensor system. An overall capacitance between the electrical power transmission line and the floating ground element is greater than an overall capacitance between the floating ground element and earth ground.
Abstract:
An endoscope control system comprises one or more sensors located in a headrest and configured to detect an input at the headrest. The one or more sensors include at least one of an array of pressure sensors positioned adjacent to a forehead rest surface, a joystick controller mounted in the headrest, or a slip plate mounted to the headrest. The endoscope control system further comprises an endoscope control module configured to receive one or more sensor signals from the sensors indicating movement of the headrest or pressure applied to the headrest and providing an indication of intended movement of an image provided by an endoscope. The endoscope control system further comprises an endoscope manipulation module configured to receive the indication of intended movement from the endoscope control module and generate one or more actuation signals to activate one or more actuators configured to cause the intended movement of the image.
Abstract:
In one embodiment, a minimally invasive surgical system includes a patient side manipulator, a hermetically sealed endoscopic camera instrument, a vision cart, and a monitor. The patient side manipulator has a robotic arm. The endoscopic camera instrument has a housing at a proximal end to couple to the robotic arm. The endoscopic camera instrument further has a hermetically sealed camera sensor at a distal end, a shaft coupled to the housing, and a wristed joint coupled between the shaft and the camera sensor. The vision cart has a camera control unit coupled in communication with the hermetically sealed camera sensor to capture the images of the surgical site. The monitor is coupled in communication with the camera control unit to display the captured images of the surgical site.
Abstract:
Control of the endoscope in a surgical system is described. In some embodiments, the endoscope can be controlled by movement of the surgeon's head or face at a surgeon's console. In some embodiments, the endoscope can be controlled using sensors integrated with a surgeon's headrest mounted on the surgeon's console.
