  • Patent number: 10758297
    Abstract: A surgical instrument has an end effector disposed on an elongate shaft end, the shaft projecting from a handle. The end effector grasps, cuts, and seals and/or coagulates tissue, and one of the operations is controlled by a rotatable drive shaft contained within the elongate shaft. The drive shaft moves longitudinally within the elongate shaft to move the end effector between a first and second condition. The instrument may have a further component such as a cutting blade arranged to move longitudinally within the drive shaft. The drive shaft is provided with apertures so as to reduce the surface area of the drive shaft and hence the friction between either the drive shaft and the elongate shaft and/or the drive shaft and the cutting blade, whilst at the same time providing channels through the drive shaft through which fluid can drain.

  • Patent number: 10413348
    Abstract: An arrangement having a device for providing high-frequency voltage UApp for contact coagulation of the biological tissue. The device is equipped to operate with a high voltage that is normally not suitable for contact coagulation, but otherwise used for spark coagulation, for example, more than 400V at the beginning of the contact coagulation. During the operation of the generator the tissue impedance Z is monitored. This can occur by means of continuously measuring the voltage UApp of the flowing current IApp and the phasing ? between the voltage and the flowing current. Using both, the measuring unit continuously determines the tissue impedance Z. A minimum detector is provided to determine if an impedance minimum Zmin has passed through and if such is found, to induce the generator control to reduce the voltage UApp delivered by the device to a value that avoids spark generation as well as desiccation of the tissue.

  • Patent number: 10111701
    Abstract: A bipolar electrosurgical forceps device having a handle at the proximal end and forceps jaws at the distal end is described. These two ends are connected via an elongated tubular section that houses the actuating member for controlling the motion of the forceps at the distal end relative to the motion of the proximal handle. A dovetail member connects the forceps to a shaft that is slidably disposed in the tubular section at the distal end of the device, where the tubular section constrains the motion of the two jaws perpendicular relative to the axial direction. A coupling member is attached to the actuating member where drive slots interact with the drive pins on the forceps, whereby squeezing the handle causes the desired relative parallel opening or closing motion of the forceps jaws.
