摘要： A surgical safety apparatus for use in connection with an energizable surgical device prevents inadvertent activation of a surgical tool. The energizable surgical device may include an electrosurgical system, a laser scalpel, an ultrasonic aspirator, and combinations thereof. An activation circuit is in connection with the source of energy and in connection with the handpiece. The activation circuit has two states: the first state disconnects the source of energy from the handpiece, the second state connects the source of energy to the handpiece. A sensing element is connected to the activation circuit. The sensing element signals the activation circuit to convert the activation circuit from the first state to the second state. The activation circuit may remain in the second state for a preestablished period of time followed by a reversion to the first state. The activation circuit may include a relay which may be connected to operate accessories including smoke evacuators, lights, videos or irrigators. The sensing element may be disposed to sense the proximity of the surgical tool to the surgical site. The sensing element may be disposed to sense a voice command. The sensing element can monitor the activations of an electrical switch associated with the surgical tool. If the sensing element detected a specified timed pattern of activations of the electrical switch, for example a double click, then the sensing element would signal the activation circuit to convert to the second state.

摘要： A clamping force mechanism for use with electrosurgery allow a user to seal and/or join patient's particular vascular tissue; the mechanism is elongate with user and patient ends. An actuator is at the user end and the effectors are at the patient end. Each effector has a face of an area to contact the particular vascular tissue. A lost motion connection transfers user actuation to the effectors to hold a predetermined clamping force during electrosurgical tissue sealing. A yielding member in the loss motion connection clamps the particular tissue between the faces with a predetermined force. The yielding member is a spring, slip clutch or hydraulic coupling possibly near the actuator. An active electrode is carried on one end effector and a return electrode contacts the tissue so an electrosurgical energy supply connected thereacross delivers energy therebetween. A feedback circuit responds to parameters of energy delivered to tissue. A temperature sensor on one face and an impedance monitor respond to energy delivered. A control applies energy to held tissue to seal and/or join it.

摘要： A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy through tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.

摘要： Electrosurgical energy is used in combination with a surgical tool to seal vessels and vascular tissue of a patient. One of the important advances of the present system is that it can effectively seal vessels of a patient without leaving any foreign material in the body of the patient. The present system is also capable of sealing vessels as large as ten millimeters in diameter. Another advantage of the present system is that the surgeon can visually inspect the integrity of the seal. The invention works with a combination of pressure and controlled application of electrosurgical energy to achieve the desired result. A surgical tool is used to grasp and apply an appropriate amount of closure force to the tissue of the patient. The tool is capable of conducting electrosurgical energy to the tissue concurrently with the application of the closure force. A method for sealing vessels and vascular tissue of a patient includes the steps of applying pressure to the vessels and other tissues of the patient; applying a first level of electrosurgical power to the vessels and other tissue sufficient to melt proteins in the tissue; applying a second level of electrosurgical power to the vessels and other tissue sufficient to cause desiccation without charring; reducing the electrosurgical power substantially to zero for a length of time sufficient to allow the vessels and other tissues to cool into a new compressed form; and relieving the pressure on the tissue.
