  • Patent number: 8845667
    Abstract: A surgical tool such as a grasper or a pair of surgical scissors includes a hinge portion that spans between a handle proximal portion and a distal working portion to communicate mechanical actions of the handle proximal portion to the distal working portion. A programmable rotary module is coupled to the hinge portion and includes a sensor, an actuator, and a controller. The sensor, actuator, and controller may be enclosed in a common housing. The sensor measures rotation of the distal working portion and the actuator generates haptic effects to the proximal handle portion. A controller is electrically connected to the sensor and to the actuator. The controller receives the rotation measurements from the sensor and, based upon the rotation measurements, outputs a control signal to the actuator relating to the generation of haptic effects. The haptic effects may include force sensations such as detents and barriers.

  • Publication number: 20140171999
    Abstract: A retaining member for a surgical instrument insert is described. The instrument insert includes a retaining member which is free to move along the shaft before the insert is attached to the handle. The retaining member comprises a resilient member integrally formed with the retaining member. The resilient member can engage the surgical instrument insert shaft and act to prevent the retaining member falling off before the insert is attached to the handle. Because the resilient member is integrally formed the cost of manufacture is reduced. In another embodiment, a surgical instrument insert is provided wherein a proximal portion of the outer shaft is manufactured from an insulating material. The insulating material can be cheaper than the aluminum conventionally used. As a further advantage this also reduces the risk of electric shock and bums when used in an electrically live environment.
