Surgical Instrument

摘要

In order to further develop a surgical instrument with an energy-driven operating device, an energy storage device as well as a control device for driving the operating device as required and supplying it with energy from the energy storage device such that an optimum utilization of the capacity of the energy storage device is achieved without any risk for the surgeon or the patient, in particular in view of the different energy requirements of the individual operating processes, it is suggested that when a predetermined state of residual charge of the energy storage device is reached and/or it is fallen below for the first time the control device make its residual charge available for returning the tool into a rest position.

主权项

1. Surgical instrument, comprising:
an energy-driven operating device, an energy storage device, and a control device for supplying the operating device with energy from the energy storage device, wherein
the operating device comprises a tool, the tool having an end or operating position and a rest position,the control device supplies the operating device with energy as required for operating the tool,when a state of charge of the energy storage device has either reached a predetermined state of a residual charge or has fallen below the predetermined state of the residual charge for a first time, the control device makes the residual charge available for returning the tool into the rest position,the energy storage device comprises a gas cartridge,the control device comprises a monitoring unit for detecting the state of charge of the energy storage device,the monitoring unit comprises a pneumatically actuatable valve allowing activation of the tool of the operating device and, where applicable, a transfer of the tool of the operating device from the rest position into the end or operating position as long as the state of charge of the gas cartridge is above the predetermined state of residual charge.
