    Abstract: A combined electrocoagulator-suction instrument useful for coagulating bleeding capillaries and veins within a surgical field and for sucking out blood and other liquids from the field either during, before or after the coagulation procedure. An elongate body of electrically non-conductive material is formed with a main flow passage terminating at one end of the body in a nipple for connecting the passage to a vacuum source. A second passage through the body receives an electrical conductor connected to an electro-surgical generator, the end of the conductor passing through the second passage and having its bared end bent back to extend into the interior of the first passage. An open ended metal tube has one end formed to be inserted into the main passage at the end opposite to said nipple, the tube being mechanically seated within the passage in electrical contact with the bared wire end. An electrically non-conductive sheath surrounds all of the exposed surface of the tube with the exception of a short section at the opposite end or tip. A branch passage extends through the wall of the body to communicate with the main passage at a location intermediate the ends of the main passage, the opposite end of the branch passage opening at the exterior of the body at a vent opening which can be fully or partially covered by the surgeon''s finger to regulate the degree of suction within the main flow passage. The vent opening is offset from the location at which the branch passage communicates with the main passage in an upstream direction with respect to the direction of flow of fluid through the main passage.

    Abstract: PROBLEM TO BE SOLVED: To measure the connecting state of pressure given to a transcutaneous passage to a user's peritoneal cavity, to put it in the concrete, to measure the openability of the passage. SOLUTION: The supply and output tube 13 of gaseous argon supplies prescribed measuring gas. A duct 16 with the gas of some volume selectively distributes measuring gas to a passage within a body cavity. This gaseous argon supply and output tube periodically connects a passage and the duct 16 to the body cavity to allow the pressure transducer 17 of the duct 16 to generate a signal. A circuit tests a signal that the pressure and the back pressure of a tube is balanced. A signal monitor 20 stores the pressure of the body cavity before connecting the converter of the duct 16 to a measured and supplied gas, and compares the stored pressure with the back pressure. A plurality of orifices supply a specific gas stream for a hand set and a valve to make the function of the stream to balance with the measured and supplied gas.

    Abstract: PURPOSE: To achieve simplification of handling a tubular body by equipping the interior side of the tunnel with at least one of the resonance member inside the tunnel and with a fin extending radially in relation to the axis, and forming a longitudinal length hole which forms a concentric tunnel along the axis. CONSTITUTION: A tubular body 1 equipped with a fin extending radially has a longitudinal length hole which forms a central tunnel 8 having a concentric cross section with the axis of the tubular body. The tubular body forming a transducer contains 36 pieces of strip having a V-shaped cross section about 6.7cm long and the diameter of the tunnel 8 is determined to be large enough to accommodate the connection unit. Further, each strip which forms the fin is soldered or welded to a face ring 6 at its close and to a face ring 7 at its remote end, respectively. The transducer is equipped with the central tunnel 8 which accommodates connecting member 2 crossing the screw at the close end where the connecting part is connected to the transducer by putting the close end of the screw in the female screw of the face ring 6.

    Abstract: PURPOSE: To monitor a feedback electrode with low reaction with an electrosurgical knife current interference when monitoring is continued during an electrosurgical knife operation by adding the patient himself to the monitor of the continuity of a patient feedback circuit. CONSTITUTION: An electrosurgical knife generator 10 includes a known high-frequency oscillator 12 and an output amplifier 14 which generates an electrosurgical knife current. The electrosurgical knife current is fed back to the generator via a split feedback electrode 18 consisting of electrodes 20, 22 and two pieces of patient conductor cables 24 consisting of lead wires 26, 28. The primary winding 40 of a transformer 38 is connected to a patient impedance detecting circuit 42. The current is impressed to a threshold circuit to determine whether the impedance is within a range meeting the patient's physiological characteristics or not. This patient impedance detecting circuit 42 processes the voltage appearing between the conductors 20 and 22 so as to output EREM which is the magnitude of the impedance between the electrodes 20 and 22. This current is fed back to the circuit 42 by passing the electrode 20, the patient and through the electrode 22 and the conductor 28.
