摘要:
An inflatable restraint module mounting mechanism is disclosed for use in mounting an inflatable restraint module to a support structure such as the hub portion of a steering wheel or a dashboard, on a vehicle. The inflatable restraint module is provided with a plurality of pin members which are adapted to pass through and be retained within apertures in a support plate. The pin members are slidable through the apertures and include clip members for engaging the support plate to thereby retain the restraint module on the support plate. The clip members are formed of a resilient material whereby the clip members are adapted to bias locking members radially outwardly for engaging the support plate and to prevent the pin members from separating from the apertures.

A motor vehicle steering wheel having a structural frame including a metal hub, a metal rim, a hollow, thin-walled metal tube having opposite distal ends rigidly connected to the rim, and a thick-walled metal sleeve disposed around a center portion of the metal tube. The metal sleeve and the center portion of the metal tube are squeezed concurrently such that each defines an oval shape in cross section in a plane perpendicular to a longitudinal centerline of the metal tube and the metal tube is mechanically interlocked with the metal sleeve. The metal sleeve is resistance welded to the metal hub whereby the metal tube on opposite sides of the metal sleeve defines a pair of low mass, hollow spokes of the structural frame and the sleeve defines a pair of spoke bases whereat the spokes are rigidly connected to the hub.

An inflatable restraint module mounting mechanism is disclosed for use in mounting an inflatable restraint module to a support structure such as the hub portion of a steering wheel. The inflatable restraint module is provided with a plurality of mounting members which are adapted to pass through and be retained within apertures in a support plate. The mounting members each include a slot for receiving a spring which traverses across the apertures of the support plate. The slots are preferably sized such that the mounting members are supported for limited movement in a direction longitudinal of the mounting members to permit actuation of a horn circuit. In addition, the springs are movable in a lateral direction to facilitate insertion of the mounting members through the apertures in the support plate.

A surgical instrument includes a handpiece having a user input feature and a user feedback feature. A shaft assembly extends distally from the handpiece. An end effector is disposed at a distal end of the shaft assembly. The end effector includes an active feature responsive to actuation of the user input feature. The active feature is operable to operate on tissue in response to actuation of the user input feature. The user feedback feature is operable to provide feedback to the user that indicates information relating to operation of the end effector. The feedback may include haptic, visual, and/or auditory feedback.

Various embodiments of surgical robot control systems are disclosed. In one example embodiment, the surgical robot control system comprises a housing. A controller is located within the housing and is coupled to a socket. The socket receives a handheld surgical user interface therein to control a surgical instrument. The surgical instrument is connected to the surgical robot and comprises an end effector and a mechanical interface to manipulate the end effector. The mechanical interface is coupled to the controller. At least one sensor is coupled to the controller and the socket to convert movement of the handheld surgical user interface into electrical signals corresponding to the movement of the surgical instrument. At least one feedback device is coupled to the controller to provide feedback to a user. The feedback is associated with a predetermined function of the surgical instrument.

Tissue manipulation devices are disclosed. In various forms, the devices include tissue manipulation arms that are arranged in a position suitable to enable the device to be inserted into the colon then, upon application of at least one actuation motion thereto, at least some of the tissue manipulation arms are moved to deployed positions wherein they contact corresponding portions of the colon to thereby expand the colon. Various devices are actuatable by various forms of actuation forces. In various embodiments, the tissue manipulation arms may be movable along corresponding axes that are transverse to an insertion axis and may also be rotated about the insertion axis as well as be moved in directions that are substantially parallel to the insertion axis.

Circular stapling instruments and anvil assemblies. The anvil assemblies may have collapsible anvil support members that may be inserted through an opening in a patient and then expanded to be attached to an anvil plate assembly that has a staple-forming surface thereon. The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed.

An ultrasonic surgical instrument includes a reusable handle assembly and a removable and disposable transmission assembly. The handle assembly includes a trigger, a housing having a distal aperture formed in a distal end of the housing, a button disposed on a top surface of the housing, and a biasing member in communication with the button. The transmission assembly includes a proximal shaft, a rotator knob having a coupling feature, a distal shaft assembly extending distally from the proximal shaft, and an end effector at the distal end of the distal shaft assembly. The biasing member of the handle assembly is adjustably coupled to the coupling feature of the transmission assembly. Another version includes a movable yoke configured to engage an inner tube of the transmission assembly. Yet another version includes a waveguide of the transmission assembly non-threadably coupled to a transducer via a biasing force.

An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.
