An electrically operated surgical instrument includes a surgical end effector having an actuation assembly effecting a surgical procedure when actuated and a handle connected to the end effector for actuating the assembly. A part of the assembly moves between start and fully actuated positions. The handle has a self-contained power supply and a drive assembly disposed entirely within the handle. The drive assembly has an electrically powered motor and a controller electrically connected to the power supply and to the motor. The controller selectively operates the motor. A transmission mechanically connects the motor to the moving part and selectively displaces the moving part anywhere between the start and fully extended positions when the motor is operated. A manual release is mechanically coupled to the transmission to selectively interrupt the transmission and, during interruption, displaces the moving part towards the start position independent of motor operation.

A cutting and stapling device for use as an attachment to an electromechanical device driver comprises an upper jaw and a lower jaw which separate and close against one another in a continuously parallel alignment. The upper jaw includes a series of staple guides corresponding to one or more staples in a removable staple tray disposed within a lower jaw, whereby a blade and wedge having a threaded bore travel upon a matching threaded shaft in a channel disposed in the lower jaw below the staple tray, such that rotation of the threaded shaft causes movement of the wedge through the channel while a sloped surface of the wedge contacts the staples to push the staples against the staples guides, closing the staples.

A system and method for monitoring vital signs and capturing data from a patient remotely using radiotelemetry techniques. The system is characterized by a cordless, disposable sensor band with sensors form measuring full waveform ECG, full waveform respiration, skin temperature, and motion, and transmission circuitry for the detection and transmission of vital signs data of the patient. A small signal transfer unit that can either be worn by the patient, e.g., on his or her belt, or positioned nearby receives data from the sensor band, which it then forwards by e.g., radio transmission to a base station that can be located up to 60 meters away. The base station receives data transmissions from the signal transfer unit and is designed to connect to conventional phone lines for transferring the collected data to a remote monitoring station. The base station may also capture additional clinical data, such as blood pressure data, and to perform data checks. Patient safety is enhanced by the ability of the base station to compare clinical data, e.g., ECG, against given profiles and to mark events when appropriate or when the base station is programmed to do so. Such events are indicated to the physician and could be indicated to the patient by reverse transmission to the signal transfer unit. A remote monitoring station allows the presentation and review of data (including events) forwarded by the sensor band. ECG analysis software and a user-friendly graphical user interface are provided to remotely analyze the transmitted data and to permit system maintenance and upkeep. The system of the invention has useful application to the collection of patient clinical data during drug trials and medical testing for regulatory approvals as well as management of patients with chronic diseases.
