Abstract:
An electrosurgical device comprising: forceps including: (i) a first working arm having a contact surface and (ii) a second working arm having a contact surface; wherein the forceps has a first electrical configuration where the contact surface of the first working arm and the contact surface of the second working arm are substantially opposite each other so that the contact surfaces of the forceps can be used to grip an item between the working arms and so that the forceps is configured to deliver a first therapy current through the first working arm, the second working arm, or both; and wherein the forceps has second electrical configuration where the contact surface of the first working arm and the contact surface of the second working arm are askew relative to each other and an electrode edge is formed on at least one side of the forceps so that a second therapy current extends from the electrode edge.
Abstract:
An electrosurgical system comprising: a handpiece including: a first power connector; a second power connector; and one or more moveable members having a first position and a second position; and an activation circuit having a first switch state and a second switch state, wherein the activation circuit in the first switch state does not allow either a first electrosurgical therapy signal or a second electrosurgical therapy signal to exit the handpiece; wherein when the activation circuit is in the second switch state and the one or more moveable members are in the first position the activation circuit allows the first electrosurgical therapy signal to exit the handpiece so that a first therapy current extends between the first power connector and the second power connector, and wherein when the activation circuit is in the second switch state and the one or more moveable members are in the second position the activation circuit allows the second electrosurgical therapy signal to exit the handpiece so that a second therapy current extends between the first power connector and the second power connector.
Abstract:
A blade assembly comprising: a tip including two or more tubes, wherein the two or more tubes include at least: an outer tube and an inner tube; and a mechanical enclosure including: a locking spline having a longitudinal axis; and a slide lock; wherein the slide lock slides along the longitudinal axis of the locking spline and over the locking spline forming a locked state so that rotational movement of the locking spline, around the longitudinal axis of the locking spline, is prevented; and wherein the outer tube is coupled to the locking spline so that rotational movement of the outer tube, around the longitudinal axis of the locking spline, is prevented during the locked state.
Abstract:
An interchangeable tip comprising: a stylet; a blade module including: an enclosure that electrically connects, signally connects, or both the interchangeable tip to a power source, a signal source, or both; and blade circuitry having: one or more control buttons, one or more switches, or both for controlling operation one or more functions of the interchangeable tip.
Abstract:
A medical instrument comprising a flexible, filamentous shaft slideably disposed in a sheath, the instrument including an electronic imaging system comprising an image sensor carried on a distal end portion of the instrument. The shaft may be used as a guidewire for a complementary guided device, or it may be used to carry a functional element for performing a procedure at a target site in a patient's body. In other embodiments, the present invention contemplates a flexible sheath, preferably having a simple tubular construction, with an electronic imaging system at its distal end. The sheath is adapted to slideably receive a shaft, preferably a filamentous shaft, that closely fits the sheath. The shaft carries functional element at its distal end. The instruments according to the present invention may include one or more filaments along their length for deflecting an insertable portion of the instrument.
Abstract:
A medical device for debridement can include an elongate housing, a shaft extending through the housing and distally therefrom, a drive to manipulate the cutter, and a collapsible handle than can to couple with the housing. An elongate grip of the handle can turn aft and be at least partially disposed in the elongate housing for use of the device with pen grip. The elongate grip of the handle can turn fore and extend distally from the housing for use of the device with pistol grip.
Abstract:
An endoscopy system can include or use an endoscopic overtube, sized and shaped for insertion into a patient esophagus towards a patient duodenum. The overtube can include and access lumen providing an inner diameter to receive and pass a cholangioscope therethrough. The distal portion of the overtube can include or use a side port sized and shaped to permit lateral exit of a distal portion of the cholangioscope. Also, the overtube can include a ramp arranged to re-direct the distal portion of the cholangioscope from a longitudinal direction in the access lumen toward the lateral exit of the side port.
Abstract:
A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.
Abstract:
An endoscope system can include a control handle, a primary scope, an auxiliary scope, and a guide. The primary scope can extend from the control handle to a distal portion and can be configured for insertion into a passage of a patient, the primary scope can define a working channel extending therethrough. The auxiliary scope can be located at least partially within the working channel and can be movable to extend from the primary scope. The guide can be extendable from the distal portion of the primary scope to guide extension of the auxiliary scope from the primary scope.
Abstract:
Medical devices, such as forceps including a handpiece having a housing and an inner shaft that extends out of the handpiece along a longitudinal axis to transfer motion to an end effector. The inner shaft being rotatable with respect to the handpiece. An outer shaft that is rotatable with respect to the housing is loated around the inner shaft. The medical device further including an end effector coupled to the inner shaft and the outer shaft. The outer shaft rotationally constrained to the inner shaft at a first longitudinal location and at a second longitudinal location.
