Abstract:
A light-emitting display driver architecture and a method of supplying power and data thereto are disclosed. The driver architecture includes a wire interface with a host controller electrically connected thereto. Further, first and second pixel nodes are connected to the wire interface in parallel. The first and second pixel nodes each include a communication unit, a control unit, a driver, and a light-emitting element. A data signal and a power signal is then transmitted from the host controller through the wire interface, in which data is extracted from the data signal for the first pixel node based upon a fixed unique ID corresponding to the first pixel node.
Abstract:
A light emitting apparatus and a method of displaying an image therewith is disclosed. The light emitting apparatus includes a spine and a rib. The rib is attached to the spine and includes a plurality of alternating nodes and connection links. At least one of the connection links is thinner in cross-section than at least one of the nodes. The light emitting apparatus then further includes a connector to attach multiple light emitting apparatuses together. The light emitting apparatus further includes a plurality of pixels, in which the pixels are configured to receive a data signal and power.
Abstract:
A handle for a surgical instrument is described. The handle comprises a housing for attachment to an outer shaft of a surgical instrument and defining a longitudinal axis. An adjustment member comprises a first bevel gear mounted for rotation about an adjustment axis perpendicular to the longitudinal axis. A second bevel gear is engaged with the first bevel gear and mounted to rotate about an axis parallel to the longitudinal axis. A translatable member is provided for attachment to an inner member of a surgical instrument and is configured to move relative to the housing along the longitudinal axis in response to rotation of the second bevel gear. In one embodiment the handle is for a minimally invasive surgical instrument having a segment string at its distal end. The configuration of the handle allows one handed use. The adjustment member can be operated by the same hand which is holding the handle. A surgical instrument including the handle is also described.
Abstract:
A handle for a surgical instrument is described comprising: a body member for attachment to an outer shaft of a surgical instrument; a rotatable member at least partially disposed within the body member for rotation about a longitudinal axis and comprising a first helical thread formed on an outer surface and a second helical thread; a translatable member for attachment to an inner shaft of a surgical instrument, adapted for movement along the longitudinal axis relative to the rotatable member and having a helical thread engaged with the second helical thread of the rotatable member; a shuttle member disposed around the rotatable member comprising a ratchet mechanism having a pawl for engaging the first helical thread; and an actuation member having a first end pivotally attached to the body member and a second end coupled to the shuttle member. This construction provides greater mechanical advantage and control over movement of the translatable member, and therefore the relative movement of an inner shaft of a surgical instrument attached to the handle.
Abstract:
Control members (200) and (202) extend through segments (3) in a retractor. When a wire (10) is tightened to urge each of the segments (3) to turn, the segments (3) having the weaker control member (200) move first to cause the distal end to turn before the segments (3) having the stronger control members (202) start to turn.
Abstract:
A handle (3) for a surgical instrument, and in particular a handle for use with keyhole surgery, endoscopic and laparoscopic instruments is disclosed. In one embodiment, the present invention provides a handle for a surgical instrument comprising one part with a pivoting or articulated end portion (4b), and a means for indexing the pivoting movement of the end portion. The indexing means allows adjustment of the angle of the end portion together with improved control and tactile feedback to the user. In another aspect, the present invention provides a handle for a surgical instrument comprising one part with a pivoting or articulated end portion, and a means for locking the movement of the end portion. The locking means can be moved between locked and unlocked positions. The end portion can be pivoted or articulated to a desired angle and the locking means moved to a position to prevent movement of the end portion holding it at the desired angle. This improves control and tactile feedback to the user.
Abstract:
An apparatus and method for supplying power to an externally powered device are disclosed herein. The apparatus includes a housing, a power supply unit disposed therein, a first cover and a second cover. The first cover is removably secured to a first end of the housing, and the second cover is removably secured to a second end of the housing. Further, the apparatus is configured to electrically connect to the externally powered device.
Abstract:
A surgical positioning assembly for use with a surgical instrument which has an elongated shaft defining a longitudinal axis, for example a minimally invasive surgical instrument. The positioning assembly comprises: a base member comprising a skin contact surface, wherein the base member defines an opening for the elongated shaft; a rotating assembly configured to rotate relative to the base member about a rotation point located below the skin contact surface wherein the rotating assembly defines an opening for the elongated shaft; and a locking mechanism for locking the position of the positioning assembly on the elongated shaft and for locking the orientation of the rotating assembly relative to the base member. In use, the elongated shaft of the surgical instrument will exert stress on the abdominal wall as the shaft is moved relative to abdominal wall. It has been found that the stress on the abdominal wall is reduced if the rotation point is below the skin of the patent. As a further benefit the reduced stress allows easier movement of the surgical instrument.
Abstract:
A handle (2) for a surgical instrument is described. The handle comprises a housing (4) for attachment to an outer shaft of a surgical instrument and defining a longitudinal axis. An adjustment member (6) comprises a first bevel gear (12) mounted for rotation about an adjustment axis perpendicular to the longitudinal axis. A second bevel gear (26) is engaged with the first bevel gear and mounted to rotate about an axis parallel to the longitudinal axis. A translatable member (36) is provided for attachment to an inner member of a surgical instrument and is configured to move relative to the housing along the longitudinal axis in response to rotation of the second bevel gear. In one embodiment the handle is for a minimally invasive surgical instrument having a segment string at its distal end. The configuration of the handle allows one handed use. The adjustment member can be operated by the same hand which is holding the handle. A surgical retractor instrument (44) including the handle is also described
Abstract:
A surgical instrument includes an elongate portion arranged, in use, to be inserted through a restricted opening into a body, the elongate portion being movable from a first configuration to a second, different configuration in which second configuration two parts of the instrument that are spaced from each other in the first configuration at least partially cross each other in second configuration. In particular the instrument comprises a segmented rod (7), which is initially straight. Segments (3, 32, 35, 36, 38, 40, 42) may be moved such that there is a crossover at two locations.
