摘要： A biological forceps device is disclosed for the taking of tissue samples from a body. The biopsy forceps device comprises a flexible main coil having a distal end which is stiffer than the majority of the coil, a pair of opposed jaws hingedly disposed on the distal end of the coil, and an actuator having a distal end coupled to the hingedly disposed jaws for effecting articulation of the jaws. Preferably, shrink wrap tubing is placed on the distal end of the coil and acts as the stiffening agent thereof. A stiffer distal end permits the practitioner to press the jaws deeper into the tissue and reduces the jump experienced at the distal end when the coils go from a state of tension (jaws open) to a state of compression (jaws closed), so that a better sample can be obtained.

摘要： A method of maintaining a constant movement of a cutting blade of an ultrasonic waveguide includes providing an ultrasonic transducer operable to convert a received motional current into a movement of a cutting blade of an ultrasonic waveguide, a measurement circuit connected in a parallel configuration with the ultrasonic transducer, and a variable power source operable to supply current through a set of connection points to the parallel configuration and thereby create the motional current in the ultrasonic transducer. Current is supplied through a set of connection points of the parallel configuration with the variable power source to, thereby, create the motional current in the ultrasonic transducer and the motional current is regulated with a current controller by varying an output of the power source, thereby maintaining a substantially constant rate of movement of the cutting blade across a variety of cutting loads.

摘要： A surgical stapling instrument includes a handle having a stapler-closing device. A surgical stapling end effector is connected to the handle and has a pair of opposing stapling surfaces. At least one of the stapling surfaces is operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween. At least one variable member is operable to receive the compressive force applied to the tissue and to exhibit at least one of mechanical and electrical change associated with the received compressive force. The change influences a surgical procedure on the compressed tissue.

摘要： An electrically powered surgical instrument includes a surgical end effector having a surgical procedure effecting actuation assembly. A handle is coupled with the end effector. An electric motor is disposed within a shell of the handle and has power terminals and a drive train actuating the assembly when the motor is supplied with power. A break-before-make power supply switch at the handle selectively controls supply of power to the motor. A post-termination braking circuit electrically short-circuits the power terminals when the switch does not supply power to the motor. A method for post-termination braking of an electrical motor utilizes the permanent magnetic field of the motor to counteract an inertia-induced over-stroke characteristic of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power to the motor.

摘要： A method for delivering RF energy to living tissue includes the steps of extending a guidewire to a tissue treatment site in a body. A controllable stiffness catheter is provided with a stiffness device having non-metallic properties and a temperature-changing device. The stiffness device is in a stiff state below a given temperature and in a soft state above the given temperature. While supplying power to the temperature-changing device, the catheter is threaded along the guidewire up to the treatment site in the soft state. Power is removed from the temperature-changing device to alter the non-metallic properties of the stiffness device and directly result in a change of the stiffness device to the stiff state without straightening the catheter. The RF energy supply device is physically contacted with the treatment site and RF energy is delivered to the treatment site from the RF energy supply device.
