摘要： An electrosurgical bipolar forceps for sealing is disclosed. The forceps includes one or more shaft members having an end effector assembly disposed at the distal end. The end effector assembly includes two jaw members movable from a first position to a closed position wherein the jaw members cooperate to grasp tissue at constant pressure. Each of the jaw members includes an electrically conductive sealing plate connected to a first energy source which communicates electrosurgical energy through the tissue held therebetween. The electrosurgical energy is communicated at constant voltage. The electrically conductive sealing plates are operably connected to sensor circuitry which is configured to measure initial tissue impedance and transmit an initial impedance value to a controller. The controller determines the constant pressure and the constant voltage to be applied to the tissue based on the initial impedance value.

摘要： To provide a tracheostomy tube which can be easily attached to and detached from an incision site and in which sputum or the like does not readily longer, a tracheostomy tube A includes a lumen body 10 having an airway securing lumen 10b, a connector section 11 formed at the base end portion of the lumen body 10, and a cuff 13 which is formed on the outer circumference of the tip end portion of the lumen body 10 and which can be expanded and contracted. A circumferential wall 10a of the lumen body 10 defines a cuff-expanding lumen 15 which puts the surface portion of the connector section 11 in communication with the inside of the cuff 13. it also defines a suction lumen 14 allowing the surface portion of the connector section 11 to communicate with the surface portion of the lumen body 10. A coating layer exhibiting surface lubricity in moisture is formed on the surface of the tracheostomy tube A and the inner surface of the lumen body 10 in which the airway securing lumen 10b is formed.
