A video endoscope system includes a reusable control cabinet and an endoscope that is connectable thereto. The endoscope may be used with a single patient and then disposed. The endoscope includes an illumination mechanism, an image sensor, and an elongate shaft having one or more lumens located therein. An articulation joint at the distal end of the endoscope allows the distal end to be oriented by the actuators in the control cabinet or actuators in a control handle of the endoscope. Fluidics, electrical, navigation, image, display and data entry controls are integrated into the system along with other accessories.

Fluid manifold for endoscope system

Ultrasonic blade coupler comprising a blade element composed of a material selected from aluminum and titanium rendered sharpenable by a surface hardening treatment. The blade coupler exhibits improved acoustical properties with reduced energy consumption.

Titanium alloy blade coupler coated with nickel-chrome for ultrasonic

A delivery system for attaching and detaching an ultrasonic surgical blade/coupler and an acoustical mount. An adaptor sleeve receives and encapsulates the blade to avoid accidents resulting from the sharp blade edge. A cylindrical member receives the sleeve and a ratcheting mechanism is provided between the adaptor and member to facilitate rotation of the adaptor and coupler upon rotation of the member up to a predetermined torque, ensuring threaded connection between the coupler and acoustical mount sufficient for transmission of ultrasonic energy. To remove the blade/coupler, the member is rotated in the opposite direction, whereby unlimited torque may be applied through the ratchet mechanism to unthread the coupler from the mount.

Apparatus and methods for attaching and detaching an ultrasonic actuated

A delivery system for attaching and detaching an ultrasonic surgical blade/coupler and an acoustical mount. An adaptor sleeve receives and encapsulates the blade to avoid accidents resulting from the sharp edge of the blade. In a two-piece embodiment hereof, a cylindrical member receives the sleeve and a ratcheting mechanism is provided between the adaptor and member to facilitate rotation of the adaptor and coupler upon rotation of the member up to a predetermined torque, ensuring threaded connection between the coupler and acoustical mount sufficient for transmission of ultrasonic energy. To remove the blade/coupler, the member is rotated in the opposite direction, whereby unlimited torque may be applied through the ratchet mechanism to unthread the coupler from the mount. In a one-piece embodiment hereof, the adaptor integrally carries an element pivotal for movement about an axis parallel to the axis of the sleeve to engage one or the other of projections on the adaptor flange to rotate the adaptor in either direction. In one direction, the element slips past the projection at a predetermined magnitude of torque.

This connection system has particular application to releasably securing a flexible catheter to a rigid portal outlet stem received in the catheter lumen. The system includes a radial enlargement on the outlet stem and a retainer sleeve having a tubular distal segment which encircles the catheter at a location adjacent to the free end of the stem therein and a proximal segment which is composed of a pair of mirror image, hinged together, semicylindrical clamping sections, one of which is an integral extension of the distal sleeve segment and the other of which can be moved between open and closed positions so as to enable the sections to clamp around the stem enlargement and a segment of the catheter encircling the stem. A locking ring snugly encircles the sleeve and is slidable therealong between a locking position wherein it tightly engages around the sleeve clamping sections and an unlocking position wherein it encircles the distal sleeve segment. The system assures a secure, fluid-tight connection of the catheter to the stem and provides strain relief for the catheter.
