摘要： A battery-powered, modular surgical device includes an electrically powered surgical instrument operable to surgically interface with human tissue and a handle assembly connected to the surgical instrument. The handle assembly has a removable hand grip and a handle body. The hand grip is shaped to permit handling of the surgical device by one hand of an operator, has an upper portion and a cordless internal battery assembly that powers the surgical instrument. The internal battery assembly has at least one energy storage cell. The handle body is operable to removably connect at least the upper portion of the hand grip thereto and create an aseptic seal around at least a portion of the hand grip when connected thereto and electrically couple the internal battery assembly of the hand grip to the surgical instrument and thereby power the surgical instrument for interfacing surgically with the human tissue.

摘要： A circuit for generating a radio-frequency signal for a surgical device is disclosed. The circuit has a voltage regulator that supplies direct current (DC) voltage, a first MOSFET, a second MOSFET, and a MOSFET driver. The MOSFET driver receives the DC voltage supplied from the voltage regulator and has a local oscillator. The local oscillator switches the first MOSFET and the second MOSFET on and off at a frequency generated by the local oscillator. The circuit further includes a transformer connected to the first and second MOSFETs, having a center tap and a main voltage applied at the center tap, and providing an alternating current (AC) output.

摘要： A surgical device assembly includes a vessel-sealing end effector having opposing surfaces engaging tissue when disposed therebetween, at least one of the surfaces having an energy delivering component, and a surgical device handle. The surgical device handle is connected to the end effector and has a switch with a switch-actuation direction in which the switch actuates, an unactuated position at a rest point of the switch, a first actuated position at first distance from the rest point in the switch-actuation direction, a second actuated position at a second distance further from the rest point in the switch-actuation direction than the first distance, and a force required to sustain the first actuated position being less than a force required to enter the second actuated position. The energy delivering component delivers energy when in at least one of the first and second actuated positions.

摘要： A battery-powered, modular surgical device comprising an electrically powered surgical instrument that requires a pre-determined minimum amount of electrical energy to complete a surgical procedure, and a power module assembly that has a battery that powers the surgical instrument and has a current state of electrical charge, and a control circuit that is electrically coupled to the battery and the surgical instrument and has a memory and a microprocessor. The microprocessor determines the current state of electrical charge of the battery, compares the current state of electrical charge to the pre-determined minimum amount of electrical energy, permits the battery to discharge if the current state of electrical charge is above the pre-determined minimum amount of electrical energy, and maintains the battery in a non-discharge state if the current state of electrical charge is below the pre-determined minimum amount of electrical energy.
